Subject: drm/connector: Split out orientation quirk detection (v2)

Not every platform needs quirk detection for panel orientation, so
split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.

Hans de Goede (changes in v2):

Rename the function from drm_connector_init_panel_orientation_property
to drm_connector_set_panel_orientation[_with_quirk] and pass in the
panel-orientation to set.

Beside the rename, also make the function set the passed in value
only once, if the value was set before (to a value other then
DRM_MODE_PANEL_ORIENTATION_UNKNOWN) make any further set calls a no-op.

This change is preparation for allowing the user to override the
panel-orientation for any connector from the kernel commandline.
When the panel-orientation is overridden this way, then we must ignore
the panel-orientation detection done by the driver.

Subject: drm: panel: fix excessive stack usage in td028ttec1_prepare

With gcc -O3 in combination with the structleak plug, the compiler can
inline very aggressively, leading to rather large stack usage:

drivers/gpu/drm/panel/panel-tpo-td028ttec1.c: In function 'td028ttec1_prepare':
drivers/gpu/drm/panel/panel-tpo-td028ttec1.c:233:1: error: the frame size of 2768 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
 }

Marking jbt_reg_write_*() as noinline avoids the case where
multiple instances of this function get inlined into the same
stack frame and each one adds a copy of 'tx_buf'.

The compiler is clearly making some bad decisions here, but I
did not open a new bug report as this only happens in combination
with the structleak plugin.

This fixes mmtom ("init/Kconfig: enable -O3 for all arches")

Subject: drm/drm_panel: fix export of drm_panel_of_backlight, try #3

Making this IS_REACHABLE() was still wrong, as that just determines
whether the lower-level backlight code would be reachable from the panel
driver. However, with CONFIG_DRM=y and CONFIG_BACKLIGHT_CLASS_DEVICE=m,
the drm_panel_of_backlight is left out of drm_panel.o but the condition
tells the driver that it is there, leading to multiple link errors such as

ERROR: "drm_panel_of_backlight" [drivers/gpu/drm/panel/panel-sitronix-st7701.ko] undefined!
ERROR: "drm_panel_of_backlight" [drivers/gpu/drm/panel/panel-sharp-ls043t1le01.ko] undefined!
ERROR: "drm_panel_of_backlight" [drivers/gpu/drm/panel/panel-seiko-43wvf1g.ko] undefined!

ERROR: "drm_panel_of_backlight" [drivers/gpu/drm/panel/panel-osd-osd101t2587-53ts.ko] undefined!

Change the condition to check for whether the function was actually part
of the drm module. This version of the patch survived a few hundred
randconfig builds, so I have a good feeling this might be the last
one for the export.

Subject: drm/i915/pmu: Correct the rc6 offset upon enabling

The rc6 residency starts ticking from 0 from BIOS POST, but the kernel
starts measuring the time from its boot. If we start measuruing
I915_PMU_RC6_RESIDENCY while the GT is idle, we start our sampling from
0 and then upon first activity (park/unpark) add in all the rc6
residency since boot. After the first park with the sampler engaged, the
sleep/active counters are aligned.

v2: With a wakeref to be sure

Subject: drm/i915/gt: Clear rc6 residency trackers across suspend

On suspend, the rc6 residency counters (stored in HW registers) will be
lost and cleared. However, we keep track of the rc6 residency to provide
a continuous 64b sampling, and if we see the HW value go backwards, we
assume it overflowed and add on 32b/40b -- an interesting artifact when
sampling across suspend.

Subject: drm/i915/guc: Introduce CT_ERROR

We should start using dev variants of error logging and
to simplify that introduce helper macro that will do any
necessary conversions to obtain pointer to device struct.

Subject: drm/i915/gem: Take local vma references for the parser

Take and hold a reference to each of the vma (and their objects) as we
process them with the cmdparser. This stops them being freed during the
work if the GEM execbuf is interrupted and the request we expected to
keep the objects alive is incomplete.

Subject: drm/i915: Make a copy of the ggtt view for slave plane
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever
it is present. We copy that from the master plane to the slave plane,
but we fail to copy the corresponding ggtt view. Thus when it comes time
to pin the slave plane's fb we use some stale ggtt view left over from
the last time the plane was used as a non-slave plane. If that previous
use involved 90/270 degree rotation or remapping we'll try to shuffle
the pages of the new fb around accordingingly. However the new
fb may be backed by a bo with less pages than what the ggtt view
rotation/remapped info requires, and so we we trip a GEM_BUG().

Steps to reproduce on icl:
1. plane 1: whatever
   plane 6: largish !NV12 fb + 90 degree rotation
2. plane 1: smallish NV12 fb
   plane 6: make invisible so it gets slaved to plane 1
3. GEM_BUG()

Subject: drm/i915/selftests: Add a mock i915_vma to the mock_ring

Add a i915_vma to the mock_engine/mock_ring so that the core code can
always assume the presence of ring->vma.

Fixes: 8ccfc20a7d56 ("drm/i915/gt: Mark ring->vma as active while pinned")

Subject: drm/i915/dp/tgl+: Update combo phy vswing tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TGL has now a table for RBR and HBR and another table for HBR2 over
combo phys. The HBR2 one has some small changes comparing to the ICL
one, so adding two new tables and adding a function to return TGL
combo phy tables.

v2:
- reordered the tgl_combo_phy_ddi_translations_dp_hbr2 to reduce diff
(Matt)
- removed definition of rates, kept using raw number(Jani and Ville)
- changed code to use icl_get_combo_buf_trans() for non-DP as those
are equal between TGL and ICL(Matt)

Subject: drm: Add getfb2 ioctl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

getfb2 allows us to pass multiple planes and modifiers, just like addfb2
over addfb.

Changes since v2:
 - add privilege checks from getfb1 since handles should only be
   returned to master/root

Changes since v1:
 - unused modifiers set to 0 instead of DRM_FORMAT_MOD_INVALID
 - update ioctl number

Subject: drm/i915/gen11: Add additional pcode status values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I don't think we've ever hit these new error codes, but they're
documented in the gen11 pcode document, so we might as well add them to
the handler.

Subject: drm/i915/params: add i915 parameters to debugfs

Add a debugfs subdirectory i915_params with all the i915 module
parameters. This is a first step, with lots of boilerplate, and not much
benefit yet.

This will result in a new device specific debugfs directory at
/sys/kernel/debug/dri/<N>/i915_params duplicating the module specific
sysfs directory at /sys/module/i915/parameters/. Going forward, all
users of the parameters should use the debugfs, with the module
parameters being phased out.

Add debugfs permissions to I915_PARAMS_FOR_EACH(). This duplicates the
mode with module parameter sysfs, but the goal is to make the module
parameters read-only initial values for device specific parameters.

0 mode will bypass debugfs creation. Use it for verbose_state_checks
which will need special attention in follow-up work.

Subject: drm/i915/params: support bool values for int and uint params

It's not uncommon for us to switch param types between bools and ints,
often having otherwise bool semantics but -1 value for platform
default. Allow bool values (such as YyNn) for ints.

Subject: drm/i915/gt: Use the BIT when checking the flags, not the index

In converting over to using set_bit()/test_bit(), when manually
inspecting the rq->fence.flags, we need to use BIT().

Subject: drm/i915/fbc: Move the plane state check into the fbc functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of dealing with the presence/absence of the primary
plane in the higher level pre/post plane update code let's
move all that into the fbc code itself. Now the higher level
code doesn't have to think about FBC details anymore.

fbc_supported() is just a pointless wrapper for HAS_FBC(). Get
rid of it. In places where we're operating on a specific plane
we can replace this with a plane->has_fbc check to avoid
doing anything for crtcs that don't even support fbc.

Subject: fbdev: potential information leak in do_fb_ioctl()

The "fix" struct has a 2 byte hole after ->ywrapstep and the
"fix = info->fix;" assignment doesn't necessarily clear it.  It depends
on the compiler.  The solution is just to replace the assignment with an
memcpy().

Subject: OMAP: DSS2: remove non-zero check on variable r

Variable r is being initialized to zero, so the check of a non-zero
rv is redundant and can be removed.

It appears that the previous case statements set r to be -EINVAL
and the "Fallthrough" comment afterwards suggested it was going
to fall through to this non-zero check but won't because of the
break statement. Remove the confusion by removing the Fallthrough
comment too.

Subject: pxa168fb: fix release function mismatch in probe failure

The driver uses kfree() to release the resource allocated by
framebuffer_alloc(), which does not match.
Use framebuffer_release() instead to fix it.

Subject: fbcon: Adjust indentation in set_con2fb_map

Clang warns:

../drivers/video/fbdev/core/fbcon.c:915:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
        return err;

here
        if (!search_fb_in_map(info_idx))
        ^
1 warning generated.

This warning occurs because there is a space before the tab on this
line. This happens on several lines in this function; normalize them
so that the indentation is consistent with the Linux kernel coding
style and clang no longer warns.

This warning was introduced before the beginning of git history so no
fixes tab.

Fix up inconsistent usage of upper and lowercase letters in "Exynos"

"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with

The lowercase "Exynos" name is promoted by its manufacturer Samsung

Subject: fbdev: remove object duplication in Makefile

The objects in $(fb-objs) $(fb-y) $(fb-m) are linked to fb.ko .

This line adds $(fb-y) to fb-objs, so the objects from $(fb-y) are
listed twice as the dependency of the module.

It works because Kbuild trims the duplicated objects from linking,
but there is no good reason to have this line.

Subject: drm/i915/execlists: Leave resetting ring to intel_ring

We need to allow concurrent intel_context_unpin, which means avoiding
doing destructive operations like intel_ring_reset(). This was already
fixed for intel_ring_unpin() in commit 0725d9a31869 ("drm/i915/gt: Make
intel_ring_unpin() safe for concurrent pint"), but I overlooked that
execlists_context_unpin() also made the same mistake.

Reported-by: Matthew Brost <matthew.brost@intel.com>
Fixes: 841350223816 ("drm/i915/gt: Drop mutex serialisation between context pin/unpin")

Subject: drm/i915: Keep track of request among the scheduling lists

If we keep track of when the i915_request.sched.link is on the HW
runlist, or in the priority queue we can simplify our interactions with
the request (such as during rescheduling). This also simplifies the next
patch where we introduce a new in-between list, for requests that are
ready but neither on the run list or in the queue.

v2: Update i915_sched_node.link explanation for current usage where it
is a link on both the queue and on the runlists.

From 32ff621fd74496f0c33644125fb69ff175859b1f Mon Sep 17 00:00:00 2001
From: Chris Wilson <chris@chris-wilson.co.uk>
Date: Thu, 16 Jan 2020 18:47:53 +0000
Subject: drm/i915/gt: Allow temporary suspension of inflight requests

In order to support out-of-line error capture, we need to remove the
active request from HW and put it to one side while a worker compresses
and stores all the details associated with that request. (As that
compression may take an arbitrary user-controlled amount of time, we
want to let the engine continue running on other workloads while the
hanging request is dumped.) Not only do we need to remove the active
request, but we also have to remove its context and all requests that
were dependent on it (both in flight, queued and future submission).

Finally once the capture is complete, we need to be able to resubmit the
request and its dependents and allow them to execute.

v2: Replace stack recursion with a simple list.
v3: Check all the parents, not just the first, when searching for a
stuck ancestor!

Subject: drm/i915/execlists: Offline error capture

Currently, we skip error capture upon forced preemption. We apply forced
preemption when there is a higher priority request that should be
running but is being blocked, and we skip inline error capture so that
the preemption request is not further delayed by a user controlled
capture -- extending the denial of service.

However, preemption reset is also used for heartbeats and regular GPU
hangs. By skipping the error capture, we remove the ability to debug GPU
hangs.

In order to capture the error without delaying the preemption request
further, we can do an out-of-line capture by removing the guilty request
from the execution queue and scheduling a worker to dump that request.
When removing a request, we need to remove the entire context and all
descendants from the execution queue, so that they do not jump past.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/738

From: Lyude Paul <lyude@redhat.com>

Subject: drm/i915: Fix eDP DPCD aux max backlight calculations

Max backlight value for the panel was being calculated using byte
count i.e. 0xffff if 2 bytes are supported for backlight brightness
and 0xff if 1 byte is supported. However, EDP_PWMGEN_BIT_COUNT
determines the number of active control bits used for the brightness
setting. Thus, even if the panel uses 2 byte setting, it might not use
all the control bits. Thus, max backlight should be set based on the
value of EDP_PWMGEN_BIT_COUNT instead of assuming 65535 or 255.

Additionally, EDP_PWMGEN_BIT_COUNT was being updated based on the VBT
frequency which results in a different max backlight value. Thus,
setting of EDP_PWMGEN_BIT_COUNT is moved to setup phase instead of
enable so that max backlight can be calculated correctly. Only the
frequency divider is set during the enable phase using the value of
EDP_PWMGEN_BIT_COUNT.

This is based off the original patch series from Furquan Shaikh
<furquan@google.com>:

https://patchwork.freedesktop.org/patch/317255/?series=62326&rev=3

Changes since original patch:
* Remove unused intel_dp variable in intel_dp_aux_setup_backlight()
* Fix checkpatch issues
* Make sure that we rewrite the pwmgen bit count whenever we bring the
  panel out of D3 mode

v2 by Jani:
* rebase
* fix readb return value check

Subject: drm/i915: Assume 100% brightness when not in DPCD control mode

Currently we always determine the initial panel brightness level by
simply reading the value from DP_EDP_BACKLIGHT_BRIGHTNESS_MSB/LSB. This
seems wrong though, because if the panel is not currently in DPCD
control mode there's not really any reason why there would be any
brightness value programmed in the first place.

This appears to be the case on the Lenovo ThinkPad X1 Extreme 2nd
Generation, where the default value in these registers is always 0 on
boot despite the fact the panel runs at max brightness by default.
Getting the initial brightness value correct here is important as well,
since the panel on this laptop doesn't behave well if it's ever put into
DPCD control mode while the brightness level is programmed to 0.

So, let's fix this by checking what the current backlight control mode
is before reading the brightness level. If it's in DPCD control mode, we
return the programmed brightness level. Otherwise we assume 100%
brightness and return the highest possible brightness level. This also
prevents us from accidentally programming a brightness level of 0.

This is one of the many fixes that gets backlight controls working on
the ThinkPad X1 Extreme 2nd Generation with optional 4K AMOLED screen.

Subject: drm/i915: Fix DPCD register order in intel_dp_aux_enable_backlight()

For eDP panels, it appears it's expected that so long as the panel is in
DPCD control mode that the brightness value is never set to 0. Instead,
if the desired effect is to set the panel's backlight to 0 we're
expected to simply turn off the backlight through the
DP_EDP_DISPLAY_CONTROL_REGISTER.

We already do the latter correctly in intel_dp_aux_disable_backlight().
But, we make the mistake of writing the DPCD registers in the wrong
order when enabling the backlight in intel_dp_aux_enable_backlight()
since we currently enable the backlight through
DP_EDP_DISPLAY_CONTROL_REGISTER before writing the brightness level. On
the X1 Extreme 2nd Generation, this appears to have the potential of
confusing the panel in such a way that further attempts to set the
brightness don't actually change the backlight as expected and leave it
off. Presumably, this happens because the incorrect register writing
order briefly leaves the panel with DPCD mode enabled and a 0 brightness
level set.

So, reverse the order we write the DPCD registers when enabling the
panel backlight so that we write the brightness value first, and enable
the backlight second. This fix appears to be the final bit needed to get
the backlight on the ThinkPad X1 Extreme 2nd Generation's AMOLED screen
working.

Subject: drm/i915: Auto detect DPCD backlight support by default

Turns out we actually already have some companies, such as Lenovo,
shipping machines with AMOLED screens that don't allow controlling the
backlight through the usual PWM interface and only allow controlling it
through the standard EDP DPCD interface. One example of one of these
laptops is the X1 Extreme 2nd Generation.

Since we've got systems that need this turned on by default now to have
backlight controls working out of the box, let's start auto-detecting it
for systems by default based on what the VBT tells us. We do this by
changing the default value for the enable_dpcd_backlight module param
from 0 to -1.

Subject: drm/i915/gt: Report the currently active execlists request

Since commit 22b7a426bbe1 ("drm/i915/execlists: Preempt-to-busy"), we
prune the engine->active.requests list prior to preemption, thus
removing the trace of the currently executing request. If that request
hangs rather than be preempted, we conclude that no active request was
on the GPU. Fortunately, this only impacts our debugging, and not our
means of hang detection or recovery.

v2: Use from to check the current iterator before continuing, and report
active as NULL if the current request is already completed.

Auo,kd101n80-45na's connector is same as boe,tv101wum-nl6.
The most codes can be reuse.
So auo,kd101n80-45na and boe,tv101wum-nl6 use one driver file.
Add the different parts in driver data.

Subject: drm/i915/userptr: add user_size limit check

Don't allow a mismatch between obj->base.size/vma->size and the actual
number of pages for the backing store, which is limited to INT_MAX
pages.

v2: document what are missing before we can safely drop the limit check

Subject: drm/i915/userptr: fix size calculation

If we create a rather large userptr object(e.g 1ULL << 32) we might
shift past the type-width of num_pages: (int)num_pages << PAGE_SHIFT,
resulting in a totally bogus sg_table, which fortunately will eventually
manifest as:

gen8_ppgtt_insert_huge:463 GEM_BUG_ON(iter->sg->length < page_size)
kernel BUG at drivers/gpu/drm/i915/gt/gen8_ppgtt.c:463!

v2: more unsigned long
    prefer I915_GTT_PAGE_SIZE

Subject: Revert "drm/dp_mst: Remove VCPI while disabling topology mgr"

This reverts commit 64e62bdf04ab8529f45ed0a85122c703035dec3a.

This commit ends up causing some lockdep splats due to trying to grab the
payload lock while holding the mgr's lock:

The proper fix for this is probably cleanup the VCPI allocations when we're
enabling the topology, or on the first payload allocation. For now though,
let's just revert.

Subject: dt-bindings: display: sitronix,st7735r: Add Okaya RH128128T

Document support for the Okaya RH128128T display, which is a 128x128
1.44" TFT display driven by a Sitronix ST7715R TFT Controller/Driver.
It can be found on e.g. the Renesas YRSK-LCD-PMOD extension board, which
comes with various Renesas development kits (e.g. Renesas Starter Kit+
for RZ/A1H[1]).

ST7715R and ST7735R are very similar.  Their major difference is that
the former is restricted to displays of up to 132x132 pixels, while the
latter supports displays up to 132x162 pixels.

Subject: drm/mipi_dbi: Add support for display offsets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the resolution of the TFT display is smaller than the maximum
resolution supported by the display controller, the display may be
connected to the driver output arrays with a horizontal and/or vertical
offset, leading to a shifted image.

Add support for specifying these offsets.

Subject: drm: tiny: st7735r: Prepare for adding support for more displays

Currently the st7735r driver supports only a single display panel.
Prepare for adding support for other display panels by factoring out the
display-specific parameters in struct st7735r_cfg.

For now, the following parameters can be configured:
  - Display resolution,
  - Horizontal/vertical display offsets,
  - Read-write versus read-only controllers,
  - RGB versus BGR color component ordering.

Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to
st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really
specific to the Jianda JD-T18003-T01 display anymore.

Add support for the Okaya RH128128T display to the st7735r driver on
DT-enabled systems.

The RH128128T is a 128x128 1.44" TFT display driven by a Sitronix
ST7715R TFT Controller/Driver.  The latter is very similar to the
ST7735R, and can be handled by the existing st7735r driver.

Subject: drm/i915: Align engine->uabi_class/instance with i915_drm.h

In our ABI we have defined I915_ENGINE_CLASS_INVALID_NONE and
I915_ENGINE_CLASS_INVALID_VIRTUAL as negative values which creates
implicit coupling with type widths used in, also ABI, struct
i915_engine_class_instance.

One place where we export engine->uabi_class
I915_ENGINE_CLASS_INVALID_VIRTUAL is from our our tracepoints. Because the
type of the former is u8 in contrast to u16 defined in the ABI, 254 will
be returned instead of 65534 which userspace would legitimately expect.

Another place is I915_CONTEXT_PARAM_ENGINES.

Therefore we need to align the type used to store engine ABI class and
instance.

v2:
 * Update the commit message mentioning get_engines and cc stable.

Subject: drm/i915: Fix post-fastset modeset check for port sync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The post-fastset "does anyone still need a full modeset?" for
port sync looks busted. The outer loop bails out of a full modeset
is still needed by the current crtc, and then we skip forcing
a full modeset on the related crtcs. That's totally the opposite
of what we want.

The MST path has the logic mostly the other way around so it
looks correct. To fix the port sync case let's follow the MST
logic for both. So, if the current crtc already needs a modeset
we do nothing. otherwise we check if any of the related crtcs
needs a modeset, and if so we force a full modeset for the
current crtc.

And while at let's change the else if to a plain if to so
we don't have needless coupling between the MST and port sync
checks.

Subject: drm/i915: Clear most of crtc state when disabling the crtc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently we don't call intel_crtc_prepare_cleared_state() for crtcs
that are going to be entirely disabled (uapi.enable==false). That
means such crtcs will leave stale junk lying around in their states
and we have to sprinkle hw.enable checks all over before we can
look at the states. Let's change that a bit so that we aways do
the state clearing, even for fully disabled crtcs.

Note that we still keep some parts of the old state (see
intel_crtc_prepare_cleared_state() for the details) so probably
can't trust things 100% when hw.enable==false. But at least there's
less chance now that we end up looking at stale junk.

Subject: drm/i915: Prefer to use the pipe to index the ddb entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's use the pipe rather than the silly 'i' iterator from
for_each_oldnew_intel_crtc_in_state() for indexing the ddb
entries array. Maybe one day we can assume c99 and hide the
'i' entirely from sight.

sync_mode_slaves_mask is a bitmask so use PIPE_CONF_CHECK_X() for it

The strings we want to print to the on stack buffers should
be no more than
8 * 3 + strlen("(GET_SCALED_HDTV_RESOLUTION_SUPPORT)") + 1 = 61
bytes. So let's shrink the buffers down to 64 bytes.

Also switch the BUG_ON()s to WARN_ON()s if I made a mistake in
my arithmentic.

Subject: drm/i915/sdvo: Consolidate SDVO HDMI force_dvi handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the force_dvi check to a single function that can be called from
both mode validation and compute_config(). Note that currently we
don't call it from mode validation, but that will change soon.

Subject: drm/i915/gem: Store mmap_offsets in an rbtree rather than a plain
 list

Currently we create a new mmap_offset for every call to
mmap_offset_ioctl. This exposes ourselves to an abusive client that may
simply create new mmap_offsets ad infinitum, which will exhaust physical
memory and the virtual address space. In addition to the exhaustion, a
very long linear list of mmap_offsets causes other clients using the
object to incur long list walks -- these long lists can also be
generated by simply having many clients generate their own mmap_offset.

However, we can simply use the drm_vma_node itself to manage the file
association (allow/revoke) dropping our need to keep an mmo per-file.
Then if we keep a small rbtree of per-type mmap_offsets, we can lookup
duplicate requests quickly.

Subject: drm/i915/bios: check DDI port presence based on child device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Report port presence based on port presence in VBT alone, relaxing the
requirements on supported encoders (DP, DVI, or HDMI). The goal is to
make future changes easier, however there is a small risk of reporting
more ports present than before in case of dubious VBT.

Regarding the current callers of intel_bios_is_port_present(), the
potential issue might be caused by DVO_PORT_CRT being identified as port
E in dvo_port_to_port(). Hopefully no VBT has that on SKL+ which support
DP/DVI/HDMI on port E; the current CRT init code on HSW/BDW does not
care.

It's easy to confuse the drm_connector->encoder (legacy state
adjusted during modeset) and intel_connector->encoder (the statically
(sans. MST) attached encoder of the connector). For the latter
let's use intel_attached_encoder() consistently.

Subject: drm/i915/hdcp: Clean up local variables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Eliminate the inconsistencies in the hdcp code local variables:
- use dev_priv over dev
- use to_i915() instead of dev->dev_private
- initialize variables when declaring them
- a bit of declaration suffling to appease ocd

Subject: drm/panfrost: Remove core stack power management

Explicit management of the GPU's core stacks is only necessary in the
case of a broken integration with the PDC. Since there are no known
platforms which have such a broken integration let's remove the explicit
control from the driver since this apparently causes problems on other
platforms and will have a small performance penality.

The out of tree mali_kbase driver contains this text regarding
controlling the core stack (CONFIGMALI_CORESTACK):

  Enabling this feature on supported GPUs will let the driver powering
  on/off the GPU core stack independently without involving the Power
  Domain Controller. This should only be enabled on platforms which
  integration of the PDC to the Mali GPU is known to be problematic.
  This feature is currently only supported on t-Six and t-HEx GPUs.

  If unsure, say N.

Subject: drm/panfrost: Prefix interrupt handlers' names

Currently, the interrupt lines requested by Panfrost
use unmeaningful names, which adds some obscurity
to interrupt introspection (i.e. any tool based
on procfs' interrupts file).

In order to improve this, prefix each requested
interrupt with the module name: panfrost-{gpu,job,mmu}.

Subject: drm/i915: Don't use VBT for detecting DPCD backlight controls

Despite the fact that the VBT appears to have a field for specifying
that a system is equipped with a panel that supports standard VESA
backlight controls over the DP AUX channel, so far every system we've
spotted DPCD backlight control support on doesn't actually set this
field correctly and all have it set to INTEL_BACKLIGHT_DISPLAY_DDI.

While we don't know the exact reason for this VBT misuse, talking with
some vendors indicated that there's a good number of laptop panels out
there that supposedly support both PWM backlight controls and DPCD
backlight controls as a workaround until Intel supports DPCD backlight
controls across platforms universally. This being said, the X1 Extreme
2nd Gen that I have here (note that Lenovo is not the hardware vendor
that informed us of this) PWM backlight controls are advertised, but
only DPCD controls actually function. I'm going to make an educated
guess here and say that on systems like this one, it's likely that PWM
backlight controls might have been intended to work but were never
really tested by QA.

Since we really need backlights to work without any extra module
parameters, let's take the risk here and rely on the standard DPCD caps
to tell us whether AUX backlight controls are supported or not. We still
check the VBT, just so we can print a debugging message on systems that
advertise DPCD backlight support on the panel but not in the VBT.

Changes since v3:
* Print a debugging message if we enable DPCD backlight control on a
  device which doesn't report DPCD backlight controls in it's VBT,
  instead of warning on custom panel backlight interfaces.

Subject: drm/i915: Clear the GGTT_WRITE bit on unbinding the vma

While we do flush writes to the vma before unbinding (to make sure they
go through the right detiling register), we may also be concurrently
poking at the GGTT_WRITE bit from set-domain, as we mark all GGTT vma
associated with an object. We know this is for another vma, as we
are currently unbinding this one -- so if this vma will be reused, it
will be refaulted and have its dirty bit set before the next write.

Subject: drm/print: introduce new struct drm_device based WARN* macros

Add new struct drm_device based WARN* macros. These are modeled after
the core kernel device based WARN* macros. These would be preferred
over the regular WARN* macros, where possible.

These macros include device information in the backtrace, so we know
what device the warnings originate from.

Knowing the device specific information in the backtrace would be
helpful in development all around.

Subject: drm/i915/display: Make WARN* drm specific where encoder ptr is
 available

Drm specific drm_WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where intel_encoder struct pointer is available.

The conversion was done automatically with below coccinelle semantic
patch.

Subject: drm/i915/gem: Make WARN* drm specific where drm_priv ptr is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915: Make WARN* drm specific where drm_priv ptr is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915: Make WARN* drm specific where uncore or stream ptr is
 available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where intel_uncore/i915_perf_stream  struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/gt: Include a tell-tale for engine parking

We have two trace messages that rely on the function name for
distinction. However, if gcc inlines the function, the two traces end up
with the same function name and are indistinguishable. Add a different
message to each to clarify which one we hit, i.e. which phase of engine
parking we are processing.

Subject: drm/i915/execlists: Take a reference while capturing the guilty
 request

Thanks to preempt-to-busy, we leave the request on the HW as we submit
the preemption request. This means that the request may complete at any
moment as we process HW events, and in particular the request may be
retired as we are planning to capture it for a preemption timeout.

Be more careful while obtaining the request to capture after a
preemption timeout, and check to see if it completed before we were able
to put it on the on-hold list. If we do see it did complete just before
we capture the request, proclaim the preemption-timeout a false positive
and pardon the reset as we should hit an arbitration point momentarily
and so be able to process the preemption.

Note that even after we move the request to be on hold it may be retired
(as the reset to stop the HW comes after), so we do require to hold our
own reference as we work on the request for capture (and all of the
peeking at state within the request needs to be carefully protected).

Subject: drm/i915/execlists: Reclaim the hanging virtual request

If we encounter a hang on a virtual engine, as we process the hang the
request may already have been moved back to the virtual engine (we are
processing the hang on the physical engine). We need to reclaim the
request from the virtual engine so that the locking is consistent and
local to the real engine on which we will hold the request for error
state capturing.

v2: Pull the reclamation into execlists_hold() and assert that cannot be
called from outside of the reset (i.e. with the tasklet disabled).
v3: Added selftest
v4: Drop the reference owned by the virtual engine

Subject: drm/i915: Mark the removal of the i915_request from the sched.link

Keep the rq->fence.flags consistent with the status of the
rq->sched.link, and clear the associated bits when decoupling the link
on retirement (as we may wish to inspect those flags independent of
other state).

Subject: drm/i915/gem: Convert vm idr to xarray

Replace the vm_idr + vm_idr_mutex to an XArray. The XArray data
structure is now used to implement IDRs, and provides its own locking.
We can simply remove the IDR wrapper and in the process also remove our
extra mutex.

Subject: drm/i915: Clear old hw.fb & co. from slave plane's state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's do the intel_plane_copy_uapi_to_hw_state() before we bail out
due to both old and new uapi.crtc being NULL. This will drop the
reference to the old hw.fb for planes that are transitioning from
being a slave plane to simply being disabled.

Subject: drm/i915: Stop looking at plane->state in intel_prepare_plane_fb()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switch over to using explicit old/new planes states instead of
digging the old state out via plane->state. The main issue is that
plane->state will point to the uapi state which we generally don't
even want to look at.

Also it sets a bad example as using plane->state during commit_tail()
would be a bug. Here we're still holding the modeset locks so it's

Subject: drm/i915: Balance prepare_fb/cleanup_fb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

intel_prepare_plane_fb() bails early if there is no fb (or rather
no obj, which is the same thing). intel_cleanup_plane_fb() does not.
This means the steps performed by intel_cleanup_plane_fb() aren't
balanced with with what was done intel_prepare_plane_fb() if there
is no fb for the plane. These hooks get called for every plane in
the state regardless of whether they have an fb or not.

Add a matching null obj check to intel_cleanup_plane_fb() to restore
the balance.

Note that intel_cleanup_plane_fb() has sufficient protections
already in place that the imbalance doesn't cause any real problems.
But having things be in balance seems nicer anyway, and might help
avoid some surprises in the future.

Subject: drm/i915: Cleanup properly if the implicit fence setup fails
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We've already pinned the vma and fence by the time we try to
deal with implicit fencing. Properly unpin the vma and fence
if the fence setup fails instead of just bailing straight out
from .prepare_fb(). As can be expected
drm_atomic_helper_prepare_planes() will not call .cleanup_fb()
for the plane whose .prepare_fb() failed so we must do the
cleanup ourself.

v2: Rebase

Subject: drm/dp_mst: Fix clearing payload state on topology disable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The issues caused by:

commit 64e62bdf04ab ("drm/dp_mst: Remove VCPI while disabling topology
mgr")

Prompted me to take a closer look at how we clear the payload state in
general when disabling the topology, and it turns out there's actually
two subtle issues here.

The first is that we're not grabbing &mgr.payload_lock when clearing the
payloads in drm_dp_mst_topology_mgr_set_mst(). Seeing as the canonical
lock order is &mgr.payload_lock -> &mgr.lock (because we always want
&mgr.lock to be the inner-most lock so topology validation always
works), this makes perfect sense. It also means that -technically- there
could be racing between someone calling
drm_dp_mst_topology_mgr_set_mst() to disable the topology, along with a
modeset occurring that's modifying the payload state at the same time.

The second is the more obvious issue that Wayne Lin discovered, that
we're not clearing proposed_payloads when disabling the topology.

I actually can't see any obvious places where the racing caused by the
first issue would break something, and it could be that some of our
higher-level locks already prevent this by happenstance, but better safe
then sorry. So, let's make it so that drm_dp_mst_topology_mgr_set_mst()
first grabs &mgr.payload_lock followed by &mgr.lock so that we never
race when modifying the payload state. Then, we also clear
proposed_payloads to fix the original issue of enabling a new topology
with a dirty payload state. This doesn't clear any of the drm_dp_vcpi
structures, but those are getting destroyed along with the ports anyway.

Changes since v1:
* Use sizeof(mgr->payloads[0])/sizeof(mgr->proposed_vcpis[0]) instead -

Subject: drm/i915: add display engine uncore helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add convenience helpers for the most common uncore operations with
struct drm_i915_private * as context rather than struct intel_uncore *.

The goal is to replace all instances of I915_READ(),
I915_POSTING_READ(), I915_WRITE(), I915_READ_FW(), and I915_WRITE_FW()
in display/ with these, to finally be able to get rid of the implicit
dev_priv local parameter use.

The idea is that any non-u32 reads or writes are special enough that
they can use the intel_uncore_* functions directly.

v2:
- rename the file intel_de.h
- move intel_de_wait_for_* there too
- also add de fw helpers

Subject: drm/i915/bios: convert to struct drm_device logging macros.

This replaces the printk based logging macros with the struct drm_device
based logging macros.
This conversion was achieved using the following coccinelle script that
transforms based on the existence of a struct drm_i915_private device:

Subject: drm/i915/audio: convert to struct drm_device logging macros.

Converts the printk based logging macros in i915/display/intel_audio.c
to the struct drm_device based logging macros.
This transformation was achieved using the following coccinelle script
that matches the existence of the struct drm_i915_private device:

From f5df7369d5438917a679562d57d19b31ea70ada2 Mon Sep 17 00:00:00 2001
From: Rob Herring <robh@kernel.org>

Subject: dt-bindings: display: Convert a bunch of panels to DT schema

Convert all the 'simple' panels which match the constraints of the
common panel-simple.yaml schema. This conversion is based on how the
panels are documented. Some may turn out to be more complex once the
schema is applied to actual dts files.

Subject: dt-bindings: restrict properties for sitronix,st7735r

David Lechner noticed (paraphrased):
- not all properties from panel-common are applicable.
- missing optional rotation and backlight properties

Fix this by listing all allowed properties,
and do not allow other properties.

Subject: drm/i915/gem: Prevent NULL pointer dereference on missing ctx->vm

If the ctx->vm is freed before we can acquire a local reference to it,
we proceed to call i915_vm_put(NULL), which is invalid.

Subject: drm/i915: Check activity on i915_vma after confirming pin_count==0

Only assert that the i915_vma is now idle if and only if no other pins
are present. If another user has the i915_vma pinned, they may submit
more work to the i915_vma skipping the vm->mutex used to serialise the
unbind. We need to wait again, if we want to continue and unbind this
vma.

However, if we own the i915_vma (we hold the vm->mutex for the unbind
and the pin_count is 0), we can assert that the vma remains idle as we
unbind.

Subject: drm/i915: Wait on vma activity before taking the mutex

Optimistically wait for the prior vma activity before taking the mutex
to minimise the mutex hold time while unbinding. We will then verify the
vma is idle with a second wait under the mutex to ensure it is safe to
unbind.

Subject: drm/i915/dsi: Ensure that the ACPI adapter lookup overrides the bus
 num

Remove the i2c_bus_num >= 0 check from the adapter lookup function
as this would prevent ACPI bus number override. This check was mainly
there to return early if the bus number has already been found but we
anyway return in the next line if the slave address does not match.

Subject: drm: Release filp before global lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The file is not part of the global drm resource and can be released
prior to take the global mutex to drop the open_count (and potentially
close) the drm device. As the global mutex is indeed global, not only
within the device but across devices, a slow file release mechanism can
bottleneck the entire system.

However, inside drm_close_helper() there are a number of dev->driver
callbacks that take the drm_device as the first parameter... Worryingly
some of those callbacks may be (implicitly) depending on the global
mutex.

v2: Drop the debug message for the open-count, it's included with the
drm_file_free() debug message -- and for good measure make that up as
reading outside of the mutex.

v3: Separate the calling of the filp cleanup outside of
drm_global_mutex into a new drm_release_noglobal() hook, so that we can
phase the transition. drm/savage relies on the global mutex, and there
may be more, so be cautious.

Subject: drm: Avoid drm_global_mutex for simple inc/dec of dev->open_count
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since drm_global_mutex is a true global mutex across devices, we don't
want to acquire it unless absolutely necessary. For maintaining the
device local open_count, we can use atomic operations on the counter
itself, except when making the transition to/from 0. Here, we tackle the
easy portion of delaying acquiring the drm_global_mutex for the final
release by using atomic_dec_and_mutex_lock(), leaving the global
serialisation across the device opens.

Subject: drm/i915/dc3co: Avoid full modeset when EXITLINE needs to be changed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A recent change in BSpec allow us to change EXTLINE while transcoder
is enabled so this allow us to change it even when doing the first
fastset after taking over previous hardware state set by BIOS.
BIOS don't enable PSR, so if sink supports PSR it will be enabled on
the first fastset, so moving the EXTLINE compute and set to PSR flows
allow us to simplfy a bunch of code.

This will save a lot of time in all the IGT tests that uses CRC, as
when PSR2 is enabled CRCs are not generated, so we switch to PSR1, so
the previous code would compute dc3co_exitline=0 causing a full
modeset that would shutdown pipe, enable and train link.

v2: only programming EXTLINE when DC3CO is enabled

Subject: drm/i915/ehl: Ensure that the DDI selection MUX is programmed
 correctly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Perhaps in some cases the BIOS/GOP or other firmware may turn on
PHY A but may not program the MUX correctly. Therefore, re-program
PHY A if it is determined after reading the VBT that the value
programmed for the MUX bit does not match the expected value.

Subject: drm/i915/gt: Flush engine parking before release

Due to the asynchronous nature of releasing our wakerefs, we can signal
the main GT wakeref as complete before the individual engines have
cleared their own wakerefs. During shutdown we assert that the engines
are indeed parked before we release them, but for this to be always true
we need to flush their workers as well.

Subject: drm/i915/gt: Poison GTT scratch pages

Using a clear page for scratch means that we have relatively benign
errors in case it is accidentally used, but that can be rather too
benign for debugging. If we poison the scratch, ideally it quickly
results in an obvious error.

v2: Set each page individually just in case we are using highmem for our
scratch page.
v3: Pick a new scratch register as MI_STORE_REGISTER_MEM does not work
with GPR0 on gen7, unbelievably.
v4: Haswell still considers 3DPRIM a privileged register!

Subject: drm/i915/guc: Don't GEM_BUG_ON on corrupted H2G CTB

We should never BUG_ON on any corruption in CTB descriptor as
data there can be also modified by the GuC. Instead we can
use flag "is_in_error" to indicate that we will not process
any further messages over this CTB (until reset).

Subject: drm/panel: Fix boe,tv101wum-n53 htotal timing

The datasheet suggests 60 for tHFP, so let's adjust the number
accordingly.

This also makes the framerate be 60Hz as intended:
159916.0 * 1000 / ((1200 + 80 + 24 + 60)*(1920 + 20 + 4 + 10))
=> 60.00 Hz

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add new drm_core_check_all_features() function to check for a mask of
features. All features in the mask are required.

Redefine existing drm_core_check_feature() in terms of this function,
using the drm_driver_feature enum for the parameter.

v3:
- add drm_core_check_all_features() (Thomas)

v2:
- fix kernel-doc (Ville)
- add an extra variable for clarity (Ville)

Use drm_core_check_all_features() to ensure both the driver features and
the per-device driver features are taken into account when registering
debugfs files.

v3:
- files[i].driver_features == 0 actually means "don't care"

v2:
- use drm_core_check_all_features()

Subject: drm/i915/display: conversion to new struct drm_device logging macros.

This patch converts various instances of the printk based logging macros
in drm/i915/display/intel_display.c to the new struct drm_device based
logging macros.
In some instances, this involves extracting the struct drm_i915_private
device from various intel types and using it in the macros.

v2: use correct variable name in assignment over variable type.

Subject: drm/i915/dsi: conversion to struct drm_device log macros.

This converts the more straightforward instances of the printk based
logging macros with the struct drm_device based logging macros.
This transformation was achieved using coccinelle and the following
script for matching an existing struct drm_i915_private device:
@rule1@

}

New checkpatch warnings were fixed manually.

Subject: drm/i915/power: convert to struct drm_device macros in
 display/intel_display_power.c

Converts various instances of the printk based logging macros in
i915/display/intel_display_power.c to the struct drm_device based
logging macros using the following coccinelle script:

Subject: drm/i915/dp: conversion to struct drm_device logging macros.

This converts various instances of printk based logging macros in
i915/display/intel_dp.c with the new struct drm_device based logging
macros using the following coccinelle script:

}

New checkpatch warnings were fixed manually.

v2: fix merge conflict with new changes in file.

Subject: drm/i915/opregion: conversion to struct drm_device logging macros.

This converts various instances of the printk based logging macros in
i915/display/intel_opregion.c with the new struct drm_device based
logging macros using the following coccinelle script:

Subject: drm/i915/hdcp: conversion to struct drm_device based logging macros.

Converts various instances of the printk based logging macros in
i915/display/intel_hdcp.c with the struct drm_device based macros using
coccinelle. The script matches based on the existence of an existing
struct drm_i915_private device:

First pass of conversion to the new struct drm_based device logging

the following coccinelle script that transforms based on the existence
of a straightforward struct drm_i915_private device:

From d0bf45822c9969d4209137fe0e3a6425991daf56 Mon Sep 17 00:00:00 2001
From: Wambui Karuga <wambui.karugax@gmail.com>
Date: Wed, 22 Jan 2020 15:57:50 +0300
Subject: drm/i915/gem: manual conversion to struct drm_device logging macros.

Convert most of the remaining uses of the printk based logging macros to
the new struct drm_device based logging macros in drm/i915/gem.
This also involves extracting the struct drm_i915_private device
from various types, and using it in the various macros.

Subject: drm/i915: Remove 'prefault_disable' modparam

The 'prefault_disable' modparam was used by IGT to prevent a few
prefaulting operations to make fault handling under struct_mutex more
prominent. With the removal of struct_mutex, this is not as important
any more and we have almost completely stopped using the parameter. The
remaining use in execbuf is now immaterial and can be dropped without
affecting coverage.

We must re-address the idea of fault injection though.

Subject: drm/i915: Fix inconsistance between pfit.enable and scaler freeing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Despite that during hw readout we seem to have scalers assigned
to pipes, then call atomic_setup_scalers, at the commit stage in
skl_update_scaler there is a check, that if we have fb src and
dest of same size, we stage freeing of that scaler.

However we don't update pfit.enabled flag then, which makes
the state inconsistent, which in turn triggers a WARN_ON
in skl_pfit_enable, because we have pfit enabled,
but no assigned scaler.

To me this looks weird that we kind of do the decision
to use or not use the scaler at skl_update_scaler stage
but not in intel_atomic_setup_scalers, moreover
not updating the whole state consistently.

This fix is to not free the scaler if we have pfit.enabled
flag set, so that the state is now consistent
and the warnings are gone.

v2: - Put pfit.enable check into crtc specific place

Subject: drm/i915: Fix modeset locks in sanitize_watermarks()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We've added more internal things that use modeset locks and
thus we need to be prepared for intel_atomic_check() grabbing
more locks than what our initial drm_modeset_lock_all_ctx()
took. So we're missing the backoff handling here.

Also drm_atomic_helper_duplicate_state() works against us
by clearing state->acquire_ctx in anticipation of
drm_atomic_helper_commit_duplicated_state() being used to
commit the state.

We could probably just reset acquire_ctx back, but instead
let's just rewrite the whole thing without using either of
those "helpers". There's also no need to add any connectors
to the state here since we just want the new watermarks
which don't depend on connectors.

Subject: drm/lima: support heap buffer creation

heap buffer is used as output of GP and input of PP for
Mali Utgard GPU. Size of heap buffer depends on the task
so is a runtime variable.

Previously we just create a large enough buffer as heap
buffer. Now we add a heap buffer type to be able to
increase the backup memory dynamically when GP fail due
to lack of heap memory.

Subject: drm/i915/audio: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/cdclk: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/color: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/crt: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/dpio_phy: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/dpll_mgr: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/dp_mst: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

Subject: drm/i915/fbc: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/gmbus: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/lpe_audio: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/panel: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/sdvo: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/tv: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915: Tighten atomicity of i915_active_acquire vs
 i915_active_release

As we use a mutex to serialise the first acquire (as it may be a lengthy
operation), but only an atomic decrement for the release, we have to
be careful in case a second thread races and completes both
acquire/release as the first finishes its acquire.

Thread A			Thread B
i915_active_acquire		i915_active_acquire
  atomic_read() == 0		  atomic_read() == 0
  mutex_lock()			  mutex_lock()
				  atomic_read() == 0
				    ref->active();
				  atomic_inc()
				  mutex_unlock()
  atomic_read() == 1
				i915_active_release
				  atomic_dec_and_test() -> 0
				    ref->retire()
  atomic_inc() -> 1
  mutex_unlock()

So thread A has acquired the ref->active_count but since the ref was
still active at the time, it did not initialise it. By switching the
check inside the mutex to an atomic increment only if already active, we
close the race.

The aux ch is used for more than DDC, so let's give it a better
name. For maximum ease let's include both the AUX ch identifier
and the port identifier (for cases where the VBT has redefined
the relationship of the two).

Subject: drm/tidss: New driver for TI Keystone platform Display SubSystem

This patch adds a new DRM driver for Texas Instruments DSS IPs used on
Texas Instruments Keystone K2G, AM65x, and J721e SoCs. The new DSS IP is
a major change to the older DSS IP versions, which are supported by
the omapdrm driver. While on higher level the Keystone DSS resembles
the older DSS versions, the registers are completely different and the
internal pipelines differ a lot.

DSS IP found on K2G is an "ultra-light" version, and has only a single
plane and a single output. The K3 DSS IPs are found on AM65x and J721E
SoCs. AM65x DSS has two video ports, one full video plane, and another
"lite" plane without scaling support. J721E has 4 video ports, 2 video
planes and 2 lite planes. AM65x DSS has also an integrated OLDI (LVDS)
output.

Version history:

v2: - rebased on top of drm-next-2019-11-27
    - sort all include lines in all files
    - remove all include <drm/drmP.h>
    - remove select "select VIDEOMODE_HELPERS"
    - call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no
      to call it in new modeset case as it is also called in vp_enable())
    - change probe sequence and drm_device allocation (follow example in
      drm_drv.c)
    - use __maybe_unused instead of #ifdef for pm functions
    - remove "struct drm_fbdev_cma *fbdev;" from driver data
    - check panel connector type before connecting it

v3: no change

v4: no change

v5: - remove fifo underflow irq handling, it is not an error and
      it should be used for debug purposes only
    - memory tuning, prefetch plane fifo up to high-threshold value to
      minimize possibility of underflows.

v6: - Check CTM and gamma support from dispc_features when creating crtc
    - Implement CTM support for k2g and fix k3 CTM implementation
    - Remove gamma property persistence and always write color properties
      in a new modeset

v7: - Fix checkpatch.pl --strict issues
    - Rebase on top of drm-misc-next-2020-01-10

v8: - Remove idle debug prints from dispc_init()
    - Add Reviewed-by: Benoit Parrot <bparrot@ti.com>

v9: - Rename dispc_write_irqenable() to dispc_set_irqenable() to avoid
      conflict exported omapfb function with same name

+	  SoCs released with DSS. Each with somewhat different version
+	  of it. The SoCs are 66AK2Gx, AM65x, and J721E. Set this to Y
+	  or M to add display support for TI Keystone family
+	  platforms.

Subject: drm/i915/pipe_crc: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/sprite: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/vdsc: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/vlv_dsi: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/vlv_dsi_pll: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/gt: Acquire ce->active before ce->pin_count/ce->pin_mutex

Similar to commit ac0e331a628b ("drm/i915: Tighten atomicity of
i915_active_acquire vs i915_active_release") we have the same race of
trying to pin the context underneath a mutex while allowing the
decrement to be atomic outside of that mutex. This leads to the problem
where two threads may simultaneously try to pin the context and the
second not notice that they needed to repin the context.

Subject: drm/i915: Skip capturing errors from internal contexts

We don't want to report errors on the internal contexts to userspace,
suppressing their own, so treat them as simulated errors. These mostly
arise inside selftests and so are simulated anyway. For the rest, we can
rely on the normal debug channels in CI.

Subject: drm/i915/gt: Reorganise gen8+ interrupt handler

We always use a deferred bottom-half (either tasklet or irq_work) for
processing the response to an interrupt which means we can recombine the
GT irq ack+handler into one. This simplicity is important in later
patches as we will need to handle and then ack multiple interrupt levels
before acking the GT and master interrupts.

Subject: drm/i915/gt: Lift set-wedged engine dumping out of user paths

The user (e.g. gem_eio) can manipulate the driver into wedging itself,
allowing the user to trigger voluminous logging of inconsequential
details. If we lift the dump to direct calls to intel_gt_set_wedged(),
out of the intel_reset failure handling, we keep the detail logging for
what we expect are true HW or test failures without being tricked.

Subject: drm/todo: Add item for the plane->atomic_check confusion

It's frankly a mess, and the confusion around plane_state->crtc/fb
that I fixed up in this series is the least of the problems. Add a
todo as a future note of how this could be done a lot better, and with
a lot less driver confusion.

+Improve plane atomic_check helpers
+----------------------------------
+
+Aside from the clipped coordinates right above there's a few suboptimal things
+with the current helpers:
+
+- drm_plane_helper_funcs->atomic_check gets called for enabled or disabled
+  planes. At best this seems to confuse drivers, worst it means they blow up
+  when the plane is disabled without the CRTC. The only special handling is
+  resetting values in the plane state structures, which instead should be moved
+  into the drm_plane_funcs->atomic_duplicate_state functions.
+
+- Once that's done, helpers could stop calling ->atomic_check for disabled
+  planes.
+
+- Then we could go through all the drivers and remove the more-or-less confused
+  checks for plane_state->fb and plane_state->crtc.

Don't confuse the poor developer by writing a negative value as a very
large positive, as the flow of requests is already complex enough.

Subject: drm/auth: Drop master_create/destroy hooks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

vmwgfx stopped using them.

With the drm device model that we've slowly evolved over the past few
years master status essentially controls access to display resources,
and nothing else. Since that's a pure access permission check drivers
should have no need at all to track additional state on a per file
basis.

Aside: For cleanup and restoring kernel-internal clients the grand
plan is to move everyone over to drm_client and
drm_master_internal_acquire/release, like the generic fbdev code
already does. That should get rid of most ->lastclose implementations,
and I think also subsumes any processing vmwgfx does in
master_set/drop.

Subject: drm/i915/icl_dsi: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/combo_phy: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/ddi: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

From: Jani Nikula <jani.nikula@intel.com>
Date: Mon, 27 Jan 2020 20:26:06 +0200
Subject: drm/i915/display: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register

Subject: drm/i915/display_power: use intel_de_*() functions for register
 access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Subject: drm/i915/dp: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/hdcp: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:

Subject: drm/i915/psr: use intel_de_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

We've long had the more generic /dev/drm_dp_auxN devices for the same
purpose. Drop the redundant and limited DPCD debugfs file.

Subject: drm/i915/execlist: Mark up racy read of execlists->pending[0]

We write to execlists->pending[0] in process_csb() to acknowledge the
completion of the ESLP update, outside of the main spinlock. When we
check the current status of the previous submission in
__execlists_submission_tasklet() we should therefore use READ_ONCE() to
reflect and document the unsynchronized read.

Subject: drm/i915/gt: Hook up CS_MASTER_ERROR_INTERRUPT

Now that we have offline error capture and can reset an engine from
inside an atomic context while also preserving the GPU state for
post-mortem analysis, it is time to handle error interrupts thrown by
the command parser.

This provides a much, much faster mechanism for us to detect known
problems than using heartbeats/hangchecks, and also provides a mechanism
for when those are disabled. However, it is limited to problems the HW
can detect in the CS and so not a complete solution for detecting lockups.

Subject: drm/i915/execlists: Ignore discrepancies in pending[] across resets

When we reset the engine, we first remove the guilty request from the
active list. If it so happens that there is a pending preemption event
to process before we handle the reset, when we inspect that event we
find ourselves a little confused as we have bent the rules slightly to
perform the reset.

Just ignore any discrepancies inside reset, we know we'll start again
from scratch afterwards.

Subject: drm: Initialize struct drm_crtc_state.no_vblank from device settings

At the end of a commit, atomic helpers can generate a fake VBLANK event
automatically. Originally implemented for writeback connectors, the
functionality can be used by any driver and/or hardware without proper
VBLANK interrupt.

The patch updates the documentation to make this behaviour official:
settings struct drm_crtc_state.no_vblank to true enables automatic
generation of fake VBLANK events.

The new interface drm_dev_has_vblank() returns true if vblanking has
been initialized for a device, or false otherwise. Atomic helpers use
this function when initializing no_vblank in the CRTC state in
drm_atomic_helper_check_modeset(). If vblanking has been initialized
for a device, no_blank is disabled. Otherwise it's enabled. Hence,
atomic helpers will automatically send out fake VBLANK events with any
driver that did not initialize vblanking.

v5:
	* more precise documentation and commit message
v4:
	* replace drm_crtc_has_vblank() with drm_dev_has_vblank()
	* add drm_dev_has_vblank() in this patch
	* move driver changes into separate patches
v3:
	* squash all related changes patches into this patch

Subject: drm/xen: Explicitly disable automatic sending of vblank event

The atomic helpers automatically send out fake VBLANK events if no
vblanking has been initialized. This would apply to xen, but xen has
its own vblank logic. To avoid interfering with the atomic helpers,
disable automatic vblank events explicitly.

Subject: drm/i915/gt: Skip global serialisation of clear_range for bxt vtd

VT'd on Broxton and on Braswell require serialisation of GGTT updates.
However, it seems to only be required for insertion, so drop the
complication and heavyweight stop_machine() for clears. The range will
be serialised again before use.

Subject: drm/i915/gt: Rename i915_gem_restore_ggtt_mappings() for its new
 placement

The i915_ggtt now sits beneath gt/ outside of the auspices of gem/ and
should be given a fresh name to reflect that. We also want to give it a
name that reflects its role in the system suspend/resume, with the
intention of pulling together all the GGTT operations (e.g. restoring
the fence registers once they are pulled under gt/intel_ggtt_detiler.c)

Subject: drm/i915: Use the async worker to avoid reclaim tainting the
 ggtt->mutex

On Braswell and Broxton (also known as Valleyview and Apollolake), we
need to serialise updates of the GGTT using the big stop_machine()
hammer. This has the side effect of appearing to lockdep as a possible
reclaim (since it uses the cpuhp mutex and that is tainted by per-cpu
allocations). However, we want to use vm->mutex (including ggtt->mutex)
from within the shrinker and so must avoid such possible taints. For this
purpose, we introduced the asynchronous vma binding and we can apply it
to the PIN_GLOBAL so long as take care to add the necessary waits for
the worker afterwards.

Subject: drm/i915: move pipe, pch and vblank enable to encoders on DDI
 platforms

To allow better flexibility for encoder specific code, push
intel_enable_pipe(), lpt_pch_enable() and intel_crtc_vblank_on() down to
the encoders from hsw_crtc_enable().

There's slight duplication, but also more clarity with the reduced
conditional statements.

Subject: drm/i915/dsi: Enable ICL DSI transcoder as part of encoder->enable

Enable the dsi transcoder, panel and backlight as part of
encoder->enable and not encoder->pre_enable. We need to have pipe src
size, among other things, set before enabling the transcoder, to avoid
FIFO underruns and possibly other issues.

v2 by Jani:
- Rebase on the crtc enable sequence update

Let's store the normal and IPS linetime watermarks individually,
and while at it we'll pimp the register definitions as well.

v2: Deal with gvt

From 751465913f045a1120188ec91ed46d90ea5fd539 Mon Sep 17 00:00:00 2001
From: Boris Brezillon <boris.brezillon@collabora.com>

Subject: drm/bridge: Add a drm_bridge_state object

One of the last remaining objects to not have its atomic state.

This is being motivated by our attempt to support runtime bus-format
negotiation between elements of the bridge chain.
This patch just paves the road for such a feature by adding a new
drm_bridge_state object inheriting from drm_private_obj so we can
re-use some of the existing state initialization/tracking logic.

v10:
* Add changelog to the commit message

v9:
* Clarify the fact that the bridge->atomic_reset() and
  {connector,plane,crtc,...}->reset() semantics are different
* Move the drm_atomic_private_obj_init() call back to
  drm_bridge_attach()
* Check the presence of ->atomic_duplicate_state instead of
  ->atomic_reset in drm_atomic_add_encoder_bridges()
* Fix copy&paste errors in the atomic bridge state helpers doc
* Add A-b/R-b tags

v8:
* Move bridge state helpers out of the CONFIG_DEBUGFS section

v7:
* Move helpers, struct-defs, ... to atomic helper files to avoid the
  drm -> drm_kms_helper -> drm circular dep
* Stop providing default implementation for atomic state reset,
  duplicate and destroy hooks (has to do with the helper/core split)
* Drop all R-b/T-b as helpers have now be moved to other places

v6:
* Made helpers private, removed doc and moved them to satisfy dependencies
* Renamed helpers to _default_

v5:
* Re-introduced the helpers from v4

v4:
* Fix the doc
* Kill default helpers (inlined)
* Fix drm_atomic_get_bridge_state() to check for an ERR_PTR()
* Add Neil's R-b

v3:
* No changes

v2:
* Use drm_for_each_bridge_in_chain()
* Rename helpers to be more consistent with the rest of the DRM API
* Improve/fix the doc

Subject: drm/bridge: Patch atomic hooks to take a drm_bridge_state

This way the drm_bridge_funcs interface is consistent with the rest of
the subsystem.

The drivers implementing those hooks are patched too.

v10:
* Add changelog to the commit message

v8 -> v9:
* No changes

v7:
* Adjust things to the bridge_state changes

v6:
* Also fixed rcar-du/rcar_lvds.c same as analogix/analogix_dp_core.c

v5:
* No changes

v4:
* Rename func params into old_bridge_state
* Add Laurent's Rb

v3:
* Old state clarification moved to a separate patch

v2:
* Pass the old bridge state

From 5061b8a969f7cd40f8d81f76e22a5e4fb13d6665 Mon Sep 17 00:00:00 2001

Subject: drm/bridge: Add an ->atomic_check() hook

So that bridge drivers have a way to check/reject an atomic operation.
The drm_atomic_bridge_chain_check() (which is just a wrapper around
the ->atomic_check() hook) is called in place of
drm_bridge_chain_mode_fixup() (when ->atomic_check() is not implemented,
the core falls back on ->mode_fixup(), so the behavior should stay
the same for existing bridge drivers).

v10:
* Add changelog to the commit message

v8 -> v9:
* No changes

v7:
* Fix a NULL pointer dereference

v5 -> v6:
* No changes

v4:
* Add R-bs

v3:
* No changes

v2:
* Clarify the fact that ->atomic_check() is replacing ->mode_fixup()

Subject: drm/i915: Move linetime wms into the crtc state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The linetime watermarks really have very little in common with the
plane watermarks. It looks to be cleaner to simply track them in
the crtc_state and program them from the normal modeset/fastset
paths.

The only dark cloud comes from the fact that the register is
still supposedly single buffered. So in theory it might still
need some form of two stage programming. Note that even though
HSW/BDWhave two stage programming we never computed any special
intermediate values for the linetime watermarks, and on SKL+
we don't even have the two stage stuff plugged in since everything
else is double buffered. So let's assume it's all fine and
continue doing what we've been doing.

Actually on HSW/BDW the value should not even change without
a full modeset since it doesn't account for pfit downscaling.
Thus only fastboot might be affected. But on SKL+ the pfit
scaling factor is take into consideration so the value may
change during any fastset.

As a bonus we'll plug this thing into the state
checker/dump now.

v2: Rebase due to bigjoiner prep
v2: Only compute ips linetime for IPS capable pipes.
    Bspec says the register values is ignored for other
    pipes, but in fact it can't even be written so the
    state checker becomes unhappy if we don't compute
    it as zero.

Subject: drm/i915: Move more cdclk state handling into the cdclk code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the initial setup of state->{cdclk,min_cdclk[],min_voltage_level[]}
into intel_modeset_calc_cdclk(), and we'll move the counterparts into
intel_cdclk_swap_state(). This encapsulates the cdclk state much better.

Subject: drm/i915: Collect more cdclk state under the same roof
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the min_cdclk[] and min_voltage_level[] arrays under the
rest of the cdclk state. And while at it provide a simple
helper (intel_cdclk_clear_state()) to clear the state during
the ww_mutex backoff dance.

intel_cdclk_needs_cd2x_update() is named rather confusingly.
We don't have to do a cd2x update, rather we are allowed to
do one (as opposed to a full PLL reprogramming with its heavy
handed modeset). So let's rename the function to
intel_cdclk_can_cd2x_update().

I want to have a higher level cdclk state object so let's rename
the current lower level thing to cdclk_config (because I lack
imagination).

Subject: drm/i915: Simplify intel_set_cdclk_{pre,post}_plane_update() calling
 convention
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move all the old vs. new state shenanigans
into intel_set_cdclk_{pre,post}_plane_update() so that the caller
doesn't need to know any of it.

Subject: drm/i915: Extract intel_cdclk_state
MIME-Version: 1.0

Use the same structure to store the cdclk state in both
intel_atomic_state and dev_priv. First step towards proper
old vs. new cdclk states.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To make life less confusing let's swap() the entire cdclk state
rather than swapping some parts, copying other parts, and leaving
the rest just as is.

Give the cdclk init/uninit functions a _hw suffix to make
it clear they are about initializing the actual hardware.
I'll be wanting to to add a intel_cdclk_init() which is
purely initializing software structures.

Subject: drm/i915: Introduce better global state handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Our current global state handling is pretty ad-hoc. Let's try to
make it better by imitating the standard drm core private object
approach.

The reason why we don't want to directly use the private objects
is locking; Each private object has its own lock so if we
introduce any global private objects we get serialized by that
single lock across all pipes. The global state apporoach instead
uses a read/write lock type of approach where each individual
crtc lock counts as a read lock, and grabbing all the crtc locks
allows one write access.

Subject: drm/i915: Convert bandwidth state to global state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we have the more formal global state thing let's
use if for memory bandwidth tracking. No real difference
to the current private object usage since we already
tried to avoid taking the single serializing lock needlessly.
But since we're going to roll the global state out to more
things probably a good idea to unify the approaches a bit.

Subject: drm/i915: Introduce intel_calc_active_pipes()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extract a small helper to compute the active pipes bitmask
based on the old bitmask + the crtcs in the atomic state.
I want to decouple the cdclk state entirely from the current
global state so I want to track the active pipes also inside
the (to be introduced) full cdclk state.

Subject: drm/i915: Convert cdclk to global state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's convert cdclk_state to be a proper global state. That allows
us to use the regular atomic old vs. new state accessor, hopefully
making the code less confusing.

We do have to deal with a few more error cases in case the cdclk
state duplication fails. But so be it.

v2: Fix new plane min_cdclk vs. old crtc min_cdclk check

Subject: drm/i915: Store active_pipes bitmask in cdclk state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's add a copy of the active_pipes bitmask into the cdclk_state.
While this is duplicating a bit of information we may already
have elsewhere, I think it's worth it to decopule the cdclk stuff
from whatever else wants to use that bitmask. Also we want to get
rid of all the old ad-hoc global state which is what the current
bitmask is, so this removes one obstacle.

The one extra thing we have to remember is write locking the cdclk
state whenever the bitmask changes.

Subject: drm/i915/gem: Require per-engine reset support for non-persistent
 contexts

To enable non-persistent contexts, we require a means of cancelling any
inflight work from that context. This is first done "gracefully" by
using preemption to kick the active context off the engine, and then
forcefully by resetting the engine if it is active. If we are unable to
reset the engine to remove hostile userspace, we should not allow
userspace to opt into using non-persistent contexts.

If the per-engine reset fails, we still do a full GPU reset, but that is
rare and usually indicative of much deeper issues. The damage is already
done. However, the goal of the interface to allow long running compute
jobs without causing collateral damage elsewhere, and if we are unable
to support that we should make that known by not providing the
interface (and falsely pretending we can).

Subject: drm/i915/gt: Also use async bind for PIN_USER into bsw/bxt ggtt

In the rare cases where we are using the global GGTT for execution in
the selftests, we have marked them with PIN_USER knowing that they will
be bound as PIN_GLOBAL as well. However, we need to catch the extra flag
in deciding to use the async worker for such binds as well.

If the heartbeat fires in the middle of the preempt-hang test, it
consumes our forced hang disrupting the test.

Subject: drm/bridge: Add the necessary bits to support bus format negotiation

drm_bridge_state is extended to describe the input and output bus
configurations. These bus configurations are exposed through the
drm_bus_cfg struct which encodes the configuration of a physical
bus between two components in an output pipeline, usually between
two bridges, an encoder and a bridge, or a bridge and a connector.

The bus configuration is stored in drm_bridge_state separately for
the input and output buses, as seen from the point of view of each
bridge. The bus configuration of a bridge output is usually identical
to the configuration of the next bridge's input, but may differ if
the signals are modified between the two bridges, for instance by an
inverter on the board. The input and output configurations of a
bridge may differ if the bridge modifies the signals internally,
for instance by performing format conversion, or*modifying signals
polarities.

Bus format negotiation is automated by the core, drivers just have
to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they
want to take part to this negotiation. Negotiation happens in reverse
order, starting from the last element of the chain (the one directly
connected to the display) up to the first element of the chain (the one
connected to the encoder).
During this negotiation all supported formats are tested until we find
one that works, meaning that the formats array should be in decreasing
preference order (assuming the driver has a preference order).

Note that the bus format negotiation works even if some elements in the
chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks.
In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets
the previous bridge element decide what to do (most of the time, bridge
drivers will pick a default bus format or extract this piece of
information from somewhere else, like a FW property).

v10:
* Add changelog to the commit message

v9:
* No changes

v8:
* Fix a test in drm_atomic_bridge_chain_select_bus_fmts() (Reported by
  Jonas)

v7:
* Adapt the code to deal with the fact that not all bridges in the
  chain have a bridge state

v5 -> v6:
* No changes

v4:
* Enhance the doc
* Fix typos
* Rename some parameters/fields
* Reword the commit message

v3:
* Fix the commit message (Reported by Laurent)
* Document the fact that bus formats should not be directly modified by
  drivers (Suggested by Laurent)
* Document the fact that format order matters (Suggested by Laurent)
* Propagate bus flags by default
* Document the fact that drivers can tweak bus flags if needed
* Let ->atomic_get_{output,input}_bus_fmts() allocate the bus format
  array (Suggested by Laurent)
* Add a drm_atomic_helper_bridge_propagate_bus_fmt()
* Mandate that bridge drivers return accurate input_fmts even if they
  are known to be the first element in the bridge chain

v2:
* Rework things to support more complex use cases

Subject: drm/imx: pd: Use bus format/flags provided by the bridge when
 available

Now that bridges can expose the bus format/flags they expect, we can
use those instead of the relying on the display_info provided by the
connector (which is only valid if the encoder is directly connected
to bridge element driving the panel/display).

We also explicitly expose the bus formats supported by our encoder by
filling encoder->output_bus_caps with proper info.

v10:
* Add changelog to the commit message
* Use kmalloc() instead of kcalloc()
* Add a dev_warn() when unsupported flags are requested

v8 -> v9:
* No changes

v7:
* Add an imx_pd_format_supported() helper (suggested by Philipp)
* Simplify imx_pd_bridge_atomic_get_output_bus_fmts() (suggested by Philipp)
* Simplify imx_pd_bridge_atomic_get_input_bus_fmts()
* Explicitly set the duplicate/destro_state() and reset() hooks

v4 -> v6:
* Patch was not part of the series

v3 (all suggested by Philipp):
* Adjust to match core changes
* Propagate output format to input format
* Pick a default value when output_fmt = _FIXED
* Add missing BGR888 and GBR888 fmts to imx_pd_bus_fmts[]

v2:
* Adjust things to match the new bus-format negotiation infra

Subject: drm/i915: extract engine WA programming to common resume function

The workarounds are a common "feature" across gens and submission
mechanisms and we already call the other WA related functions from
common engine ones (<setup/cleanup>_common), so it makes sense to
do the same with WA application. Medium-term, This will help us
reduce the duplication once the GuC resume function is added, but short
term it will also allow us to use the workaround lists for pre-gen8
engine workarounds.

Subject: drm/i915: Move ringbuffer WAs to engine workaround list

Now that intel_engine_apply_workarounds is called on all gens, we can
use the engine workaround lists for pre-gen8 workarounds as well to be
consistent in the way we handle and dump the WAs.

v2: Ignore the sanity check of MI_MODE on Broadwater, for whatever reason
it is not sticking.

Take a reference to the previous exclusive fence on the i915_active, as
we wish to add an await to it in the caller (and so must prevent it from
being freed until we have completed that task).

Subject: drm/i915: Initialise basic fence before acquiring seqno

Inside the intel_timeline_get_seqno(), we currently track the retirement
of the old cachelines by listening to the new request. This requires
that the new request is ready to be used and so requires a minimum bit
of initialisation prior to getting the new seqno.

Subject: drm/i915/gt: Warn about the hidden i915_vma_pin in timeline_get_seqno

On seqno rollover, we need to allocate ourselves a new cacheline. This
might incur grabbing a new page and pinning it into the GGTT, with some
rather unfortunate lockdep implications.

To avoid a mutex, and more specifically pinning in the GGTT from inside
the kernel context being used to flush the GGTT in emergencies, we will
likely need to lift the next-cacheline allocation to a pre-reservation.

Subject: drm/i915/display/dpll_mgr: Make WARN* drm specific where drm_device
 ptr is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/hdmi: Make WARN* drm specific where drm_device ptr
 is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch.

Subject: drm/i915/vlv_dsi_pll: conversion to struct drm_device logging macros.

Convert the printk based logging macros to the new struct drm_device
based logging macros in i915/display/vlv_dsi_pll.c using the following
coccinelle script that matches based on the existence of a drm_i915_private
device:

Subject: drm/i915/vlv_dsi: conversion to drm_device based logging macros.

Converts the printk based logging macros to the struct drm_device based
logging macros in i915/display/vlv_dsi.c.
This was done using the following coccinelle script that transforms
based on the existence of a drm_i915_private device pointer.

drm_device based logging macros in i915/display/intel_quirks.c using the
following coccinelle script that transforms based on the existence of a
struct drm_i915_private device:

From 6db07ce48887ac0da32aa244d3c2c77bfa70cf8d Mon Sep 17 00:00:00 2001
From: Wambui Karuga <wambui.karugax@gmail.com>
Date: Fri, 31 Jan 2020 12:34:13 +0300
Subject: drm/i915/debugfs: conversion to drm_device based logging macros.

Manual conversion of printk based logging macros to the struct
drm_device based logging macros in i915/i915_debugfs.c.
Also involves extracting the struct drm_i915_private device from various
intel types to use in the macros.

This does not convert various instances of the DRM_DEBUG macro due to
the lack of an analogous struct drm_device based logging macro.

Subject: drm/i915/cmd_parser: conversion to struct drm_device logging macros.

Manually convert printk based drm logging macros to the struct
drm_device based logging macros in i915/i915_cmd_parser.c.
This also involves extracting the drm_i915_private device from various
intel types for use in the macros.

Instances of the DRM_DEBUG macro are not converted due to the lack of a
similar struct drm_device based logging macro.

To write to the DISPLAY_PHY_CONTROL requires holding the powerwells,
which during early resume we have not yet acquired until later in
intel_display_power_init_hw(). So compute the initial chv_phy_control,
but leave the HW unset until we first acquire the powerwell.

Subject: drm/stm: ltdc: add number of interrupts

The number of interrupts depends on the ltdc version.
Don't try to get interrupt which not exist, avoiding
kernel warning messages.

drm_pci_alloc and drm_pci_free are just very thin wrappers around
dma_alloc_coherent, with a note that we should be removing them.
Furthermore since

    page-flags: define PG_reserved behavior on compound pages

    As far as I can see there's no users of PG_reserved on compound pages.
    Let's use PF_NO_COMPOUND here.

drm_pci_alloc has been declared broken since it mixes GFP_COMP and
SetPageReserved. Avoid this conflict by weaning ourselves off using the
abstraction and using the dma functions directly.

Subject: drm/i915: Introduce intel_connector_hpd_pin()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplify the hotplug code connector->encoder->hpd_pin handling
by introducing a helper for exactly this purpose.

In the helper we can neatly deal with the potential lack of an
attached encoder on fresh MST connectors leaving the rest of the
hpd code oblivious to such details.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's make sure encoder->hpd_pin and connector->polled are mirror
images of each other (when we want to use polling). The other
potentially polled connectors (sdvo and tv) already get this right.

Also nuke the redundant force_hotplug_required initialization
(the thing is kzalloc()ed).

The current rc6 threshold is larger than the evaluation interval on
Ivybridge; it never enters rc6. Remove the special casing so it behaves
like the other gen6/gen7, and we see rc6 residencies before we manually
park the system.

differently. In particular, since

    page-flags: define PG_reserved behavior on compound pages

    As far as I can see there's no users of PG_reserved on compound pages.
    Let's use PF_NO_COMPOUND here.

it has been illegal to combine GFP_COMP with SetPageReserved, so lets
stop doing both and leave the dma layer to its own devices.

From: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com>
Date: Thu, 12 Dec 2019 16:00:01 -0500
Subject: drm/amd/display: update psp interface header

[Why]
We need to support SRM(System Renewability Message)
As per hdcp spec (5.Renewability) SRM needs to be storage in a non-volatile
memory.

PSP owns the checking of SRM but doesn't have the ability to store it in a
non-volatile memory. So we need the kernel driver to facilitate it using the
interface provided by PSP

[How]
Add the interface to the header file, so the driver can use them

Subject: drm/i915/hdcp: move update pipe code to hdcp

The DDI encoder code shouln't have to know about the guts of
HDCP. Abstract the pipe update code to a new intel_hdcp_update_pipe() in
intel_hdcp.c. No functional changes.

Subject: drm/i915/display: Explicitly cleanup initial_plane_config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I am about to stuff more objects into the plane_config and would like to
have it clean up after itself. Move the current framebuffer release into
a common function so it can be extended with the new object with
relative ease.

Subject: drm/i915/display: Be explicit in handling the preallocated vma
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As only the display codes tries to pin its preallocated framebuffer into
an exact location in the GGTT, remove the convenience function and make
the pin management explicit in the display code. Then throughout the
display management, we track the framebuffer and its plane->vma; with
less single purpose code and ready for first class i915_vma.

In doing so, this should fix the BUG_ON(vma->pages) on fi-kbl-soraka.

Subject: drm/i915: Remove skl_ddl_allocation struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current consensus that it is redundant as
we already have skl_ddb_values struct out there,
also this struct contains only single member
which makes it unnecessary.

v2: As dirty_pipes soon going to be nuked away
    from skl_ddb_values, evacuating enabled_slices
    to safer in dev_priv.

v3: Changed "enabled_slices" to be "enabled_dbuf_slices_num"
    (Matt Roper)

v4: - Wrapped the line getting number of dbuf slices(Matt Roper)
    - Removed indeed redundant skl_ddb_values declaration(Matt Roper)

Subject: drm/i915: Move dbuf slice update to proper place
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current DBuf slices update wasn't done in proper
place, especially its "post" part, which should
disable those only once vblank had passed and
all other changes are committed.

v2: Fix to use dev_priv and intel_atomic_state
    instead of skl_ddb_values
    (to be nuked in Villes patch)

v3: Renamed "enabled_slices" to "enabled_dbuf_slices_num"
    (Matt Roper)

v4: - Rebase against drm-tip.
    - Move post_update closer to optimize_watermarks,
      to prevent unneeded noise from underrun reporting
      (Ville Syrjälä)

Subject: drm/i915: Update dbuf slices only with full modeset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During full modeset, global state(i.e dev_priv) is protected
by locking the crtcs in state, otherwise global state is not
serialized. Also if it is not a full modeset, we anyway
don't need to change DBuf slice configuration as Pipe configuration
doesn't change.

Subject: drm/i915: Introduce parameterized DBUF_CTL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now start using parameterized DBUF_CTL instead
of hardcoded, this would allow shorter access
functions when reading or storing entire state.

Tried to implement it in a MMIO_PIPE manner, however
DBUF_CTL1 address is higher than DBUF_CTL2, which
implies that we have to now subtract from base
rather than add.

v2: - Removed unneeded DBUF_CTL_DIST and DBUF_CTL_ADDR
      macros. Started to use _PICK construct as suggested
      by Matt Roper.

v3: - _DBUF_CTL_S* to DBUF_CTL_S*, changed X to "slice"
      in macro(Ville Syrjälä)
    - Introduced enum for enumerating DBUF slices(Ville Syrjälä)

Subject: drm/i915: Manipulate DBuf slices properly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Start manipulating DBuf slices as a mask,
but not as a total number, as current approach
doesn't give us full control on all combinations
of slices, which we might need(like enabling S2
only can't enabled by setting enabled_slices=1).

Removed wrong code from intel_get_ddb_size as
it doesn't match to BSpec. For now still just
use DBuf slice until proper algorithm is implemented.

Other minor code refactoring to get prepared
for major DBuf assignment changes landed:
- As now enabled slices contain a mask
  we still need some value which should
  reflect how much DBuf slices are supported
  by the platform, now device info contains
  num_supported_dbuf_slices.
- Removed unneeded assertion as we are now
  manipulating slices in a more proper way.

v2: Start using enabled_slices in dev_priv

v3: "enabled_slices" is now "enabled_dbuf_slices_mask",
    as this now sits in dev_priv independently.

v4: - Fixed debug print formatting to hex(Matt Roper)
    - Optimized dbuf slice updates to be used only
      if slice union is different from current conf(Matt Roper)
    - Fixed some functions to be static(Matt Roper)
    - Created a parameterized version for DBUF_CTL to
      simplify DBuf programming cycle(Matt Roper)
    - Removed unrequred field from GEN10_FEATURES(Matt Roper)

v5: - Removed redundant programming dbuf slices helper(Ville Syrjälä)
    - Started to use parameterized loop for hw readout to get slices
      (Ville Syrjälä)
    - Added back assertion checking amount of DBUF slices enabled
      after DC states 5/6 transition, also added new assertion
      as starting from ICL DMC seems to restore the last DBuf
      power state set, rather than power up all dbuf slices
      as assertion was previously expecting(Ville Syrjälä)

v6: - Now using enum for DBuf slices in this patch (Ville Syrjälä)
    - Removed gen11_assert_dbuf_enabled and put gen9_assert_dbuf_enabled
      back, as we really need to have a single unified assert here
      however currently enabling always slice 1 is enforced by BSpec,
      so we will have to OR enabled slices mask with 1 in order
      to be consistent with BSpec, that way we can unify that
      assertion and against the actual state from the driver, but
      not some hardcoded value.(concluded with Ville)
    - Remove parameterized DBUF_CTL version, to extract it to another
      patch.(Ville Syrjälä)
v7:
    - Removed unneeded hardcoded return value for older gens from
      intel_enabled_dbuf_slices_mask - this now is handled in a
      unified manner since device info anyway returns max dbuf slices
      as 1 for older platforms(Matthew Roper)
    - Now using INTEL_INFO(dev_priv)->num_supported_dbuf_slices instead
      of intel_dbuf_max_slices function as it is trivial(Matthew Roper)

v8: - Fixed icl_dbuf_disable to disable all dbufs still(Ville Syrjälä)

v9: - Renamed _DBUF_CTL_S to DBUF_CTL_S(Ville Syrjälä)
    - Now using power_domain mutex to protect from race condition, which
      can occur because intel_dbuf_slices_update might be running in
      parallel to gen9_dc_off_power_well_enable being called from
      intel_dp_detect for instance, which causes assertion triggered by
      race condition, as gen9_assert_dbuf_enabled might preempt this
      when registers were already updated, while dev_priv was not.

From ff2cd8635e41e0cb375ae2ad1ec05728fcd56c49 Mon Sep 17 00:00:00 2001
From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>
Date: Mon, 3 Feb 2020 01:06:30 +0200
Subject: drm/i915: Correctly map DBUF slices to pipes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added proper DBuf slice mapping to correspondent
pipes, depending on pipe configuration as stated
in BSpec.

v2:
    - Remove unneeded braces
    - Stop using macro for DBuf assignments as
      it seems to reduce readability.

v3: Start using enabled slices mask in dev_priv

v4: Renamed "enabled_slices" used in dev_priv
    to "enabled_dbuf_slices_mask"(Matt Roper)

v5: - Removed redundant parameters from
      intel_get_ddb_size function.(Matt Roper)
    - Made i915_possible_dbuf_slices static(Matt Roper)
    - Renamed total_width into total_width_in_range
      so that it now reflects that this is not
      a total pipe width but the one in current
      dbuf slice allowed range for pipe.(Matt Roper)
    - Removed 4th pipe for ICL in DBuf assignment
      table(Matt Roper)
    - Fixed wrong DBuf slice in DBuf table for TGL
      (Matt Roper)
    - Added comment regarding why we currently not
      using pipe ratio for DBuf assignment for ICL

v6: - Changed u32 to unsigned int in
      icl_get_first_dbuf_slice_offset function signature
      (Ville Syrjälä)
    - Changed also u32 to u8 in dbuf slice mask structure
      (Ville Syrjälä)
    - Switched from DBUF_S1_BIT to enum + explicit
      BIT(DBUF_S1) access(Ville Syrjälä)
    - Switched to named initializers in DBuf assignment
      arrays(Ville Syrjälä)
    - DBuf assignment arrays now use autogeneration tool
      from
      https://patchwork.freedesktop.org/series/70493/
      to avoid typos.
    - Renamed i915_find_pipe_conf to *_compute_dbuf_slices
      (Ville Syrjälä)
    - Changed platforms ordering in skl_compute_dbuf_slices
      to be from newest to oldest(Ville Syrjälä)

v7: - Now ORing assigned DBuf slice config always with DBUF_S1
      because slice 1 has to be constantly powered on.
      (Ville Syrjälä)

v8: - Added pipe_name for neater printing(Ville Syrjälä)
    - Renamed width_before_pipe to width_before_pipe_in_range,
      to better reflect that now all the calculations are happening
      inside DBuf range allowed by current pipe configuration mask
      (Ville Syrjälä)
    - Shortened FIXME comment message, regarding constant ORing with
      DBUF_S1(Ville Syrjälä)
    - Added .dbuf_mask named initializer to pipe assignment array
      (Ville Syrjälä)
    - Edited pipe assignment array to use only single DBuf slice
      for gen11 single pipe configurations, until "pipe ratio"
      thing is finally sorted out(Ville Syrjälä)
    - Removed unused parameter crtc_state for now(Ville Syrjälä)
      from icl/tgl_compute_dbuf_slices function

We have been using '-1' to mean the maximum i915.reset level in the

error, and instead of setting the default reset mechanism in igt,
we have been disabling reset!

Subject: drm/i915: Flush execution tasklets before checking request status

Rather than flushing the submission tasklets just before we sleep, flush
before we check the request status. Ideally this gives us a moment to
process the tasklets after sleeping just before we timeout.

v2: Compromise by pushing the flush prior to the timeout, but after the
check on completion so that we do not further delay the ready client.

Subject: drm/vram: Add helpers to validate a display mode's memory
 requirements

Devices with low amount of dedicated video memory may not be able
to use all possible display modes, as the framebuffers may not fit
into VRAM. The new helper function drm_vram_helper_mode_valid()
implements a simple test to sort out all display modes that can
not be used in any case. Drivers should call this function from
struct drm_mode_config_funcs.mode_valid.

The functionality was originally implemented by the ast driver, which
is being converted as well.

v2:
	* WARN_ON if VRAM memory manager has not been initialized
	* documentation fixes
	* unexported drm_vram_helper_mode_valid_internal()

Subject: drm/virtio: remove incorrect ENOSPC check

The handling of virtqueue_add_sgs ENOSPC error is incorrect because
it can result in out-of-order virtqueue_add_sgs and break fences.
We never get ENOSPC anyway because the caller waits until there is
enough space (the other caller that did not wait was removed in
commit 32d6c2c5b522 ("drm/virtio: Rewrite virtio_gpu_queue_ctrl_buffer
using fenced version.")).  Remove the incorrect and unnecessary error
path.

This also adds a WARN_ON(ret) until we properly handle errors.

Subject: drm/virtio: move the check for vqs_ready earlier

When vqs_ready is false, vq should be considered invalid and we
should not check vq->num_free.  After this change, a fenced command
queued before the vqs are ready will have fence id 0 and will be
considered done.

It becomes clear that virtio_gpu_queue_fenced_ctrl_buffer should be
responsible for setting up sgs and virtio_gpu_queue_ctrl_sgs should
be responsible for queuing sgs.

Subject: drm/amd/display: Add sysfs interface for set/get srm

[Why]
PSP doesn't have the ability to store SRM in a non-volatile memory.  And since
the kernel cannot write to the storage directly, we need usermode to facilitate
this

As per spec the SRM needs to be persistent so this interface is to be
called by the usermode anytime the system goes down/powers on

*boot/resume: load from storage
*shutdown/suspend: save to storage

[How]
Provide a sysfs interface so that the usermode can set/get srm at the right times

save to storage: call "cat /sys/class/drm/card0/device/hdcp_srm > file" after boot and resume
	-driver calls psp_get_srm() to get the stored srm and outputs it

load from storage: call "cat file > /sys/class/drm/card0/device/hdcp_srm" before shutdown and suspend
	-driver reads the file from sysfs and calls psp_set_srm() to send the SRM to PSP

v2:
-update commit description
-add comment about sysfs file handling in the code

v3:
- squash in use after free fix (Dan Carpenter)

+/* NOTE: From the usermodes prospective you only need to call write *ONCE*, the kernel

+ *
+ * call: "cat file > /sys/class/drm/card0/device/hdcp_srm" from usermode no matter what the size is
+ *
+ * The kernel can only send PAGE_SIZE at once and since MAX_SRM_FILE(5120) > PAGE_SIZE(4096),
+ * srm_data_write can be called multiple times.
+ *
+ * sysfs interface doesn't tell us the size we will get so we are sending partial SRMs to psp and on
+ * the last call we will send the full SRM. PSP will fail on every call before the last.
+ *
+ * This means we don't know if the SRM is good until the last call. And because of this limitation we
+ * cannot throw errors early as it will stop the kernel from writing to sysfs
+ *
+ * Example 1:
+ * 	Good SRM size = 5096
+ * 	first call to write 4096 -> PSP fails
+ * 	Second call to write 1000 -> PSP Pass -> SRM is set

+ * Solution?:
+ * 	1: Parse the SRM? -> It is signed so we don't know the EOF

+ * Easy Solution:

+ * |   Why it works:      |

+ * PSP will only update its srm if its older than the one we are trying to load.

+ *
+ * 	-if we try to "1. SET" a newer version PSP will accept it and we can "2. GET" the
+ * 	same(newer) version back and save it

Subject: drm/amd/display: Load srm before enabling HDCP

[Why]
we need to load SRM before we start HDCP. Because for S3 case the sysfs call will be
after we have already enabled HDCP, so we might not be using the latest SRM

[How]
Set srm before starting HDCP.

Subject: drm/amdgpu: move xgmi init/fini to xgmi_add/remove_device call (v2)

For sriov, psp ip block has to be initialized before
ih block for the dynamic register programming interface
that needed for vf ih ring buffer. On the other hand,
current psp ip block hw_init function will initialize
xgmi session which actaully depends on interrupt to
return session context. This results an empty xgmi ta
session id and later failures on all the xgmi ta cmd
invoked from vf. xgmi ta session initialization has to
be done after ih ip block hw_init call.

to unify xgmi session init/fini for both bare-metal
sriov virtualization use scenario, move xgmi ta init
to xgmi_add_device call, and accordingly terminate xgmi
ta session in xgmi_remove_device call.

The existing suspend/resume sequence will not be changed.

v2: squash in return fix from Nirmoy

Subject: drm/amd/display: Fix psr static frames calculation

[Why]
Driver crash with psr feature enabled due to divide-by-zero error.
This is a regression after rework to calculate static screen frame
number entry time.

[How]
Correct order of operations to avoid divide-by-zero.

Subject: drm/amd/display: Do not set optimized_require to false after plane
 disable

[WHY]
The optimized_require flag is needed to set watermarks and clocks lower
in certain conditions. This flag is set to true and then set to false
while programming front end in dcn20.

[HOW]
Do not set the flag to false while disabling plane.

Subject: drm/amd/display: Split program front end part that occur outside lock

[Why]
Eventually want to lock at a higher level in stack.
To do this, we need to be able to isolate the parts that need to be done
after pipe unlock.

[How]
Split out programming that is done post unlock.

Subject: drm/amd/display: Add GPINT handler interface

[Why]
The General Purpose Interrupt is used on the DMCUB to pass lightweight
commands via a register to the DMCUB.

This is limited to 32-bit command and 32-bit response.

This will be used for shutting down the firmware in a clean manner.

[How]
Add the command IDs and the data register to correctly format
the commands.

Add the interface functions to dmub_srv for sending and receiving the
commands.

Subject: drm/amd/display: Wait for clean shutdown in DMCUB reset

[Why]
The DMCUB may be currently executing commands when the reset is
triggered.

Before issuing a reset we should first wait for the DMCUB to finish
its work.

[How]
Send the GPINT command for halting the firmware before reset.

Get the ack for the command then wait for the scratch register to
become the correct value.

We want this to take under ~40us or so at most before we force reset
to cover PHY delay sequence max time.

Each register read will be at least ~1-3us so don't bother using udelay.

Subject: drm/amd/display: Fix GSL acquire

[Why]
After locking refactor GSL is not acquired properly
resulting in immediate flip issues.

[How]
Do not copy old GSL state anymore since GSL is acquired
earlier now.

Subject: drm/amd/display: Use dcfclk to populate watermark ranges

[WHY & HOW]
Previously drain clk was unconstrained and fill clk was constrained on fclk.
We want to change it to fill clk unconstrained and drain clock constrained
to dcfclk.

Subject: drm/amd/display: Check engine is not NULL before acquiring

[Why]
Engine can be NULL in some cases, so we must not acquire it.

[How]
Check for NULL engine before acquiring.

Subject: drm/amd/display: decouple global lock out of pipe control lock

[why]
hwss should not guess what type of pipe lock is needed.
The caller of the lock function should know
the right type of pipe lock.
Decouple the setup of global lock outside of pipe control lock
logic.

Subject: drm/amd/display: fix inputting clk lvl into dml for RN

[Why]
Previous logic is only good for 15W parts. Other configuration
need a smarter logic to match clk levels with pp table in the fuse.

[How]
Cache all 8 DPM level's clock data, find lvl that match each pstate
in the pp table and build input into DML base on that

[Why]
hyperV flag should be passed from dm to DC, and override the
nv12 flip workaround flag.

[How]
Add flag to phy address config struct and pass the value in dm.

[WHY & HOW]
Having watermark ranges saved inside clk_mgr to be
available for debug at all times would be useful.
Add it to the clk_mgr_internal struct for reference.
Only populated for Renoir, unused for other asics.

[WHY]
enum dc_log_type has more than 32 entries. User cannot set larger entries,
like LOG_DSC. Logs from LOG_GAMMA_DEBUG where being printed even though
flag was not enabled, because dal_logger_should_log check erroneously
passed.

[HOW]
Change struct dal_logger.mask and struct dc_init_data.mask to uint64_t.

Subject: drm/amd/display: Add DMUB tracebuffer debugfs

[Why]
The DMUB tracebuffer is useful for understanding DMCUB execution state.

[How]
Add a "show" attribute debugfs so we can loop through the buffer
and print the entries.

The structs for the entry format are defined in the debugfs since
the tracebuffer header no longer exists in the DMUB service.

Subject: drm/amd/display: fix workaround for incorrect double buffer register
 for DLG ADL and TTU

[Why]
these registers should have been double buffered. SW workaround we will have SW program the more aggressive (lower) values
whenever we are upating this register, so we will not have underflow at expense of less optimzal request pattern.

[How]
there is a driver bug where we don't check for 0, which is uninitialzed HW default.  since 0 is smaller than any value we need to program,
driver end up with not programming these registers

Subject: drm/amd/display: Add initialitions for PLL2 clock source

[Why]
Starting from 14nm, the PLL is built into the PHY and the PLL is mapped
to PHY on 1 to 1 basis. In the code, the DP port is mapped to a PLL that was not
initialized. This causes DP to HDMI dongle to not light up the display.

[How]
Initializations added for PLL2 when creating resources.

Subject: drm/amd/display: turn off the mst hub before we do detection

[why]
not turning off the mst hub before detection on reboot
causes us to not be able to light up displays with mst hook

[how]
on hw init, see if any displays are lit up. if so, turn them off

Subject: drm/amdkfd: Add queue information to sysfs

Provide compute queues information in sysfs under /sys/class/kfd/kfd/proc.
The format is /sys/class/kfd/kfd/proc/<pid>/queues/<queue id>/XX where
XX are size, type, and gpuid three files to represent queue size, queue
type, and the GPU this queue uses. <queue id> folder and files underneath
are generated when a queue is created. They are removed when the queue is
destroyed.

Subject: drm/amd/display: Fix wrongly passed static prefix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, gcc spews a warning as:
  drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_hubbub.c: In function ‘hubbub1_verify_allow_pstate_change_high’:
  ./include/drm/drm_print.h:316:2: warning: ‘debug_data’ may be used uninitialized in this function [-Wmaybe-uninitialized]

This is because the code checks against a static value although it's
basically a constant and guaranteed to be set.

This patch changes the type prefix from static to const for addressing
the compile warning above and also for letting the compiler optimize
better.

Always prime the page table registers before starting the ring. Even
though we will update these to the per-context page tables during
dispatch, it is prudent to ensure that the registers always point to a
valid PD.

Subject: drm/i915/display: Set TRANS_DDI_MODE_SELECT to default value when
 clearing DDI select
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TGL is suffering of timeouts and fifo underruns when disabling
transcoder in MST mode, this is fixed by set TRANS_DDI_MODE_SELECT to
0(HDMI mode) when clearing DDI select.

Although BSpec disable sequence don't require this step, it is a
harmless change and it is also done by Windows driver.
Anyhow HW team was notified about that but it can take some time to
documentation to be updated.

A case that always lead to those issues is:
- do a modeset enabling pipe A and pipe B in the same MST stream
leaving A as master
- disable pipe A, promote B as master doing a full modeset in A
- enable pipe A, changing the master transcoder back to A(doing a
full modeset in B)
- Pow: underruns and timeouts

The transcoders involved will only work again when complete disabled
and their power wells turned off causing a reset in their registers.

v2: Setting TRANS_DDI_MODE_SELECT to default when clearing DDI select
not anymore when disabling TRANS_DDI, both work but this one looks
more safe. (Ville comment)

Subject: drm/i915/selftests: drop igt_ppgtt_exhaust_huge

We already have tests that exhaustively exercise the most interesting
page-size combinations, along with tests that offer randomisation, and
so we should already be testing objects(local, system) with a varying
mix of page-sizes, which leaves igt_ppgtt_exhaust_huge providing not
much in terms of extra coverage.

Subject: drm/virtio: fix ring free check

If the virtio device supports indirect ring descriptors we need only one
ring entry for the whole command.  Take that into account when checking
whenever the virtqueue has enough free entries for our command.

Subject: drm/i915/gt: Prevent queuing retire workers on the virtual engine

Virtual engines are fleeting. They carry a reference count and may be freed
when their last request is retired. This makes them unsuitable for the
task of housing engine->retire.work so assert that it is not used.

Tvrtko tracked down an instance where we did indeed violate this rule.
In virtual_submit_request, we flush a completed request directly with
__i915_request_submit and this causes us to queue that request on the
veng's breadcrumb list and signal it. Leading us down a path where we
should not attach the retire.

which is us consuming a partially initialised new waiter in

Subject: Revert "drm/i915: Don't use VBT for detecting DPCD backlight
 controls"

This reverts commit d2a4bb6f8bc8cf2d788adf7e59b5b52fe3a3333c.

So, turns out that this ended up just breaking things. While many
laptops incorrectly advertise themselves as supporting PWM backlight
controls, they actually will only work with DPCD backlight controls.
Unfortunately, it also seems there are a number of systems which
advertise DPCD backlight controls in their eDP DPCD but don't actually
support them. Talking with some laptop manufacturers has shown it might
be possible to probe this support via the EDID (!?!?) but I haven't been
able to confirm that this would work on any other manufacturer's
systems.

So in the mean time, we'll just revert this commit for now and go back
to the old way of doing things.

Subject: drm/i915/gt: Protect execlists_hold/unhold from new waiters

As we may add new waiters to a request as it is being run, we need to
mark the list iteration as being safe for concurrent addition.

v2: Mika spotted that we used the same trick for signalers_list, so warn
the compiler about the lockless walk there as well.

Subject: drm/amdgpu/sriov Don't send msg when smu suspend

For sriov and pp_onevf_mode, do not send message to set smu
status, because smu doesn't support these messages under VF.

Besides, it should skip smu_suspend when pp_onevf_mode is disabled.

Subject: amdgpu: Prevent build errors regarding soft/hard-float FP ABI tags

On PowerPC, the compiler will tag object files with whether they
use hard or soft float FP ABI and whether they use 64 or 128-bit
long double ABI. On systems with 64-bit long double ABI, a tag
will get emitted whenever a double is used, as on those systems
a long double is the same as a double. This will prevent linkage
as other files are being compiled with hard-float.

On ppc64, this code will never actually get used for the time
being, as the only currently existing hardware using it are the
Renoir APUs. Therefore, until this is testable and can be fixed
properly, at least make sure the build will not fail.

Subject: drm/amdgpu: fix amdgpu pmu to use hwc->config instead of hwc->conf

hwc->conf was designated specifically for AMD APU IOMMU purposes.  This
could cause problems in performance and/or function since APU IOMMU
implementation is elsewhere.  Also hwc->conf and hwc->config are
different members of an anonymous union so hwc->conf aliases as
hw->last_tag.

Subject: drm/i915/gt: Use the kernel_context to measure the breadcrumb size

We set up a dummy ring in order to measure the size we require for our
breadcrumb emission, so that we don't have to manually count dwords! We
can pass in the kernel_context to use for this so that if required it is
known for the breadcrumb emitter, and we can reuse some details from the
kernel_context to reduce the number of temporaries we have to mock.

SIMD16 with Src0 scalar might conflict between Src1/Src2 and cause
GRF read issue. Workaround this issue by setting bit 14 in 0xe4f4
which will disable early read/src swap of Src0.

Subject: drm/i915/execlists: Always force a context reload when rewinding
 RING_TAIL

If we rewind the RING_TAIL on a context, due to a preemption event, we
must force the context restore for the RING_TAIL update to be properly
handled. Rather than note which preemption events may cause us to rewind
the tail, compare the new request's tail with the previously submitted
RING_TAIL, as it turns out that timeslicing was causing unexpected
rewinds.

Subject: drm/i915: Never allow userptr into the new mapping types

Commit 4f2a572eda67 ("drm/i915/userptr: Never allow userptr into the
mappable GGTT") made I915_GEM_MMAP_GTT IOCTLs to fail when attempted
on a userptr object in order to protect from a lockdep splat.  Later
on, new mapping types were introduced by commit cc662126b413
("drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET").  Those new mapping
types suffer from the same lockdep splat issue but they now succeed
when tried on top of a userptr object.  Fix it.

v2: Don't play with the -ENODEV driver response (Chris)

Subject: drm/i915: Remove lite restore defines

We have switched from tail manipulation to forced context restore
to implement WaIdleLiteRestore. Remove the old defines and comments.

Note: we still do emit the WA tail, and use it as our first attempt to
avoid forcing a full-restore instead of a lite-restore, we just have a
much stronger backup mechanism for repeated preemptions.

Subject: dt-bindings: one file of all simple DSI panels

To complement panel-simple.yaml, create panel-simple-dsi.yaml.
panel-simple-dsi-yaml are for all simple DSP panels with a single
power-supply and optional backlight / enable GPIO.

Migrate panasonic,vvx10f034n00 over to the new file.

The objectives with one file for all the simple DSI panels are:
    - Make it simpler to add bindings for simple DSI panels
    - Keep the number of bindings file lower
    - Keep the binding documentation for simple DSI panels more consistent

Subject: drm/i915/gt: Fix hold/unhold recursion

In eliminating the recursion from walking the tree of signalers/waiters
for processing the hold/unhold operations, a crucial error crept in
where we looked at the parent request and not the list element when
processing the list.

Brown paper bag, much?

Subject: drm/i915/execlists: Ignore tracek for nop process_csb

Recording the frequent inspection of CSB head/tail when there is
expected to be no update adds noise to the debug trace. (Not entirely
useless, but since we know the sequence of function calls, we can
surmise the function was called -- so redundant.)

Subject: drm/tiny/repaper: Make driver OF-independent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is one OF call in the driver that limits its area of use.
Replace it to generic device_get_match_data() and get rid of OF dependency.

While here, cast SPI driver data to certain enumerator type.

Subject: drm/bridge: Add tc358768 driver

Add basic support for the Toshiba TC358768 RGB to DSI bridge.
Not all the features of the TC358768 is implemented by the initial driver:
MIPI_DSI_MODE_VIDEO and MIPI_DSI_FMT_RGB888 is only supported and tested.

Only write is implemented for mipi_dsi_host_ops.transfer.

Subject: drm/bridge: sii902x: Select SND_SOC_HDMI_CODEC if SND_SOC is
 configured

To enable HDMI audio the SND_SOC_HDMI_CODEC needs to be
configured. Enable HDMI audio by selecting SND_SOC_HDMI_CODEC if
SND_SOC is configured. SND_SOC_HDMI_CODEC has no config menu entry and
should be selected automatically by the drivers using it.

Subject: drm/virtio: move virtio_gpu_mem_entry initialization to new function

Introduce new virtio_gpu_object_shmem_init() helper function which will
create the virtio_gpu_mem_entry array, containing the backing storage
information for the host.  For the most path this just moves code from
virtio_gpu_object_attach().

Subject: drm/i915/selftests: Drop live_preempt_hang

live_preempt_hang's use of hang injection has been superseded by
live_preempt_reset's use of an non-preemptible spinner. The latter does
not require intrusive hacks into the code.

Subject: drm/i915/dc3co: Add description of how it works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a basic description about how DC3CO works to help people not
familiar with it.

While at it, I also improved the delayed work handle and function
names and removed a debug message that is ambiguous and not much
useful, no changes in behavior here.

Voltage level depends not only on the cdclk, but also on the DDI clock.
Last time the bspec voltage level table for EHL was updated, we only
updated the cdclk requirements, but forgot to account for the new port
clock criteria.

Subject: drm/i915/selftests: Trim blitter block size

Reduce the amount of work we do to verify client blt correctness as
currently our 0.5s subtests takes about 15s on slower devices!

v2: Grow the maximum block size until we run out of time

Subject: drm/i915: Skip CPU synchronisation on dmabuf attachments

dma-bufs are device coherent, with explicit CPU synchronisation provided
via the begin/end cpu access ioctls. As the coherency of the dma-buf is
explicitly defined to be under user control, flushing any caches on
attach/detach of the dma-buf is additional work that doesn't aide the
user in the slightest.

Subject: drm/qxl: reorder calls in qxl_device_fini().

Reorder calls in qxl_device_fini().  Cleaning up gem & ttm
might trigger qxl commands, so we should do that before
releaseing command rings.

Subject: drm/i915/gt: Avoid resetting ring->head outside of its timeline mutex

We manipulate ring->head while active in i915_request_retire underneath
the timeline manipulation. We cannot rely on a stable ring->head outside
of the timeline->mutex, in particular while setting up the context for
resume and reset.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1126
Fixes: 0881954965e3 ("drm/i915: Introduce intel_context.pin_mutex for pin management")
Fixes: e5dadff4b093 ("drm/i915: Protect request retirement with timeline->mutex")

Subject: drm/i915/dp_link_training: convert to drm_device based logging
 macros.

Converts various instances of the printk based drm logging macros to the
struct drm_device based logging macros in
i915/display/intel_dp_link_training.c.
This also involves extracting the drm_i915_private device pointer from
the intel_dp type to use in the various macros.

Subject: drm/i915/dpll_mgr: convert to drm_device based logging macros.

Conversion of instances of printk based drm logging macros to the struct
drm_device based logging macros in i915/display/intel_dpll_mgr.c.
This also involves extracting the struct drm_i915_private device pointer
from various intel types to use in the drm_device based macros.

Note that this converts DRM_DEBUG_DRIVER to drm_dbg().

Subject: drm/i915/combo_phy: convert to struct drm_device logging macros.

Conversion of the printk based drm logging macros to the struct
drm_device based logging macros in i915/display/intel_combo_phy.c.
This transformation was achieved using the following coccinelle script
that matches based on the existence of a drm_i915_private device
pointer:

}

This converts DRM_DEBUG/DRM_DEBUG_DRIVER to drm_dbg().
New checkpatch warnings were addressed manually.

Subject: drm/i915/dsi_vbt: convert to drm_device based logging macros.

Convert various instances of the printk based drm logging macros to the
struct drm_device based logging macros in i915/display/intel_dsi_vbt.c.
This also involves extracting the drm_i915_private device from the
intel_dsi type for use in the logging macros.

This converts DRM_DEBUG/DRM_DEBUG_DRIVER to drm_dbg().

Subject: drm/ttm: refine ghost BO resv criteria
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ghost BOs need to stick with the resv object only when the origin is imported.

This is a low hanging fruit to avoid OOM situations on evictions.

Subject: drm/i915/dpio_phy: convert to drm_device based logging macros.

Conversion of the printk based logging macros to the struct drm_device
based logging macros in i915/display/intel_dpio_phy.c.
This was achieved using the following coccinelle semantic patch that
matches based on the existence of a drm_i915_private device:
@@
identifier fn, T;
@@

fn(...,struct drm_i915_private *T,...) {

}

Note that this converts both DRM_DEBUG/DRM_DEBUG_DRIVER to drm_dbg().
Checkpatch warnings were fixed manually.

Subject: drm/fbdev-helper: don't force restores
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead check for master status, in case we've raced.

This is the last exception to the general rule that we restore fbcon
only when there's no master active. Compositors are supposed to drop
their master status before they switch to a different console back to
text mode (or just switch to text mode directly, without a vt switch).

This is known to break some subtests of kms_fbcon_fbt in igt, but they're
just wrong - it does a graphics/text mode switch for the vt without
updating the master status.

Also add a comment to the drm_client->restore hook that this is expected
going forward from all clients (there's currently just one).

v2: Also drop the force in pan_display

v3: Restore the _force to pan_display, this actually means _locked in that
path. Spotted by Noralf.

Subject: drm/client: Rename _force to _locked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Plus extend the kerneldoc a bit to explain how this should be used.
With the previous patch to drop the force restore the main user of
this function is not emphasis on the "I hold the internal master lock
already" aspect, so rename the function to match.

Suggested by Noralf.

Subject: drm: Push drm_global_mutex locking in drm_open

We want to only take the BKL on crap drivers, but to know whether
we have a crap driver we first need to look it up. Split this shuffle
out from the main BKL-disabling patch, for more clarity. Historical
aside: When the kernel-wide BKL was removed, it was replaced by
drm_global_mutex within the scope of the drm subsystem hence why these
two things are (almost) interchangeable as concepts here.

Since the minors are refcounted drm_minor_acquire is purely internal
and this does not have a driver visible effect.

v2: Push the locking even further into drm_open(), suggested by Chris.
This gives us more symmetry with drm_release(), and maybe a futuer
avenue where we make drm_global_mutex locking (partially) opt-in like
with drm_release_noglobal().

v3:
- Actually push this stuff correctly, don't unlock twice (Chris)
- Fix typo on commit message, plus explain why BKL = drm_global_mutex

Subject: drm: Nerf drm_global_mutex BKL for good drivers

This catches the majority of drivers (unfortunately not if we take
users into account, because all the big drivers have at least a
lastclose hook).

With the prep patches out of the way all drm state is fully protected
and either prevents or can deal with the races from dropping the BKL
around open/close. The only thing left to audit are the various driver
hooks - by keeping the BKL around if any of them are set we have a
very simple cop-out!

Note that one of the biggest prep pieces to get here was making
dev->open_count atomic, which was done in

commit 7e13ad896484a0165a68197a2e64091ea28c9602
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Fri Jan 24 13:01:07 2020 +0000

    drm: Avoid drm_global_mutex for simple inc/dec of dev->open_count

v2:
- Rebase and fix locking in drm_open() (Chris)
- Indentation fix in drm_release
- Typo fix in the commit message (Sam)

Subject: drm/i915/selftests: Relax timeout for error-interrupt reset
 processing

We can not require that the system process a tasklet in reasonable time
(thanks be to ksoftirqd), but we can insist that having waited
sufficiently for the error interrupt to have been raised and having
kicked the tasklet, the reset has begun and the request will be marked
as in error (if not already completed).

Subject: drm/irq: remove check on dev->dev_private

There is no real reason to require drivers to set and use
dev->dev_private. Indeed, the current recommendation, as documented in
drm_device.h, is to embed struct drm_device in the per-device struct
instead of using dev_private.

Remove the requirement for dev_private to have been set to indicate
driver initialization.

For background, quoting Daniel Vetter:

Now there might be some hilarious races this papers over, but:

- Proper drivers should only call drm_dev_register once everything is
  set up, including this stuff here. No race possible with anything else
  really.

- Slightly more wobbly drivers, including the legacy ones, all use
  drm_global_mutex. This was the former BKL, which means that it was
  impossible for soeone to go through the load/unload/reload (between
  lastclose and firstopen) paths and also run the ioctl. But the ioctl
  had to be made unlocked because blocking there killed X:

	 commit 8f4ff2b06afcd6f151868474a432c603057eaf56
	 Author: Ilija Hadzic <ihadzic@research.bell-labs.com>
	 Date:   Mon Oct 31 17:46:18 2011 -0400

	     drm: do not sleep on vblank while holding a mutex

  The even more legacy DRM_CONTROL ioctl stayed fully locked. But the
  file open/close paths are still fully locked, and that's the only
  place legacy drivers should call drm_irq_install/uninstall, so should
  all still be fully ordered and protected and happy.

Subject: drm/amdgpu/sriov set driver_table address in VF

With the recent patch to unify VRAM address for driver
table(a83f82e). VF cannot dump table info any more because
SMU_MSG_SetDriverDramAddrHigh/Low were deleted in the
function of smu_update_table.

Therefore, VF also needs to set driver_table address
in smu_hw_init to fix this regression issue.

Subject: drm/amdgpu: limit GDS clearing workaround in cold boot sequence

GDS clear workaround will cause gfx failure in suspend/resume case.

[   98.679559] [drm:amdgpu_device_ip_late_init [amdgpu]] *ERROR* late_init of IP block <gfx_v9_0> failed -110
[   98.679561] PM: dpm_run_callback(): pci_pm_resume+0x0/0xa0 returns -110
[   98.679562] PM: Device 0000:03:00.0 failed to resume async: error -110

As this workaround is specific to the HW bug of GDS's ECC error
existing in cold boot up, so bypass this workaround in suspend/
resume case after booting up.

Subject: drm/amd/display: Hookup psr set version call

[Why]
Set version is currently not called.

[How]
Add call to set version from copy settings. This
should be the only time this is called as the eDP
caps should never change.

Subject: drm/amd/display: Add backlight support via AUX

Several modern displays support HDR/OLED panel, and one of the
interesting changes provided by this technology is the new approach for
handling backlight. More precisely, in the traditional way, we use PWM
to manage display backlight; however, with HDR/OLED we begin to use DP
Aux channel for adjusting the backlight.

This patch, enable the backlight control in HDR/OLED display via DP Aux.

Subject: drm/amd/display: Toggle VSR button cause system crash

[Why]
in dcn10_apply_ctx_for_surface(), if we hit !top_pipe_to_program,
pipe_ctx->update_flags could not get cleared.

[How]
Moved clearing pipe_ctx->update_flags logic before if
(!top_pipe_to_program) to gurantee pipe_ctx->update_flags get cleared.

Subject: drm/amd/display: add odm split logic to scaling calculations

Currently odm scaling calculations are only done when adding initial
odm pipe. Any scaling re-calculations will mess up odm because of this.

This change resolves the problem by updating scaling split logic to
handle odm.

Subject: drm/amd/display: Don't map ATOM_ENABLE to ATOM_INIT

[Why]
In DCN hardware sequencer we do actually call ATOM_INIT correctly per
pipe. The workaround is not necessary for command table offloading.

[How]
Drop the workaround since it's not needed.

Subject: drm/amd/display: Use fb_base/fb_offset if available for translation

[Why]
In the case where we do have these passed in then we should be using
these instead of the registers - those are only programmed when booting
the adapter as primary.

[How]
Check if fb_base/fb_offset are non-zero. The value of 0 is invalid
for fb_base but is valid for fb_offset on dGPU.

Programming DPPCLK to the same value currently set may cause
underflow while playing video in certain conditions.

Only program DPPCLK if clock is not the same as the
previous value programmed.

Subject: drm/i915: Disable use of hwsp_cacheline for kernel_context

Currently on execlists, we use a local hwsp for the kernel_context,
rather than the engine's HWSP, as this is the default for execlists.
However, seqno wrap requires allocating a new HWSP cacheline, and may
require pinning a new HWSP page in the GGTT. This operation requiring
pinning in the GGTT is not allowed within the kernel_context timeline,
as doing so may require re-entering the kernel_context in order to evict
from the GGTT. As we want to avoid requiring a new HWSP for the
kernel_context, we can use the permanently pinned engine's HWSP instead.
However to do so we must prevent the use of semaphores reading the
kernel_context's HWSP, as the use of semaphores do not support rollover
onto the same cacheline. Fortunately, the kernel_context is mostly
isolated, so unlikely to give benefit to semaphores.

Accidentally removed the 'ret=0' initialization, and thus
we're potentially looking at some stack garbage here.

The whole 'ret = do_stuff; if (!ret) do_other_stuff;' pattern
confuses my brain so let's replace it with the standard
immediate return thing.

Subject: drm/i915/gem: Don't leak non-persistent requests on changing engines

If we have a set of active engines marked as being non-persistent, we
lose track of those if the user replaces those engines with
I915_CONTEXT_PARAM_ENGINES. As part of our uABI contract is that
non-persistent requests are terminated if they are no longer being
tracked by the user's context (in order to prevent a lost request
causing an untracked and so unstoppable GPU hang), we need to apply the
same context cancellation upon changing engines.

v2: Track stale engines[] so we only reap at context closure.
v3: Tvrtko spotted races with closing contexts and set-engines, so add a
veneer of kill-everything paranoia to clean up after losing a race.

Fixes: a0e047156cde ("drm/i915/gem: Make context persistence optional")

Subject: drm/bochs: add drm_driver.release callback.

Call bochs_unload via drm_driver.release to make sure we release stuff
when it is safe to do so.  Use drm_dev_{enter,exit,unplug} to avoid
touching hardware after device removal.  Tidy up here and there.

v4: add changelog.
v3: use drm_dev_*().
v2: move hardware deinit to pci_remove().

Subject: drm/virtio: add drm_driver.release callback.

Split virtio_gpu_deinit(), move the drm shutdown and release to
virtio_gpu_release().  Drop vqs_ready variable, instead use
drm_dev_{enter,exit,unplug} to avoid touching hardware after
device removal.  Tidy up here and there.

v4: add changelog.
v3: use drm_dev_*().

Subject: drm/i915: Poison rings after use

On retiring the request, we should not re-use these elements in the ring
(at least not until we fill the ringbuffer and knowingly reuse the space).
Leave behind some poison to (hopefully) trap ourselves if we make a
mistake.

Subject: drm/ttm: rework BO delayed delete. v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch reworks the whole delayed deletion of BOs which aren't idle.

Instead of having two counters for the BO structure we resurrect the BO
when we find that a deleted BO is not idle yet.

This has many advantages, especially that we don't need to
increment/decrement the BOs reference counter any more when it
moves on the LRUs.

v2: remove duplicate ttm_tt_destroy, fix holde lock for LRU move

Subject: drm/ttm: replace dma_resv object on deleted BOs v3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When non-imported BOs are resurrected for delayed delete we replace
the dma_resv object to allow for easy reclaiming of the resources.

v2: move that to ttm_bo_individualize_resv
v3: add a comment to explain what's going on

Subject: drm/amdgpu: Fix missing error check in suspend

amdgpu_device_suspend might return an error code since it can be called
from both runtime and system suspend flows. Add the missing return code
in case of a failure.

Subject: drm/amdkfd: show warning when kfd is locked

During system suspend the kfd driver aquires a lock that prohibits
further kfd actions unless the gpu is resumed. This adds some info which
can be useful while debugging.

Subject: drm/amdkfd: refactor runtime pm for baco

So far the kfd driver implemented same routines for runtime and system
wide suspend and resume (s2idle or mem). During system wide suspend the
kfd aquires an atomic lock that prevents any more user processes to
create queues and interact with kfd driver and amd gpu. This mechanism
created problem when amdgpu device is runtime suspended with BACO
enabled. Any application that relies on kfd driver fails to load because
the driver reports a locked kfd device since gpu is runtime suspended.

However, in an ideal case, when gpu is runtime  suspended the kfd driver
should be able to:

 - auto resume amdgpu driver whenever a client requests compute service
 - prevent runtime suspend for amdgpu  while kfd is in use

This change refactors the amdgpu and amdkfd drivers to support BACO and
runtime power management.

Subject: drm/amdgpu/runpm: enable runpm on baco capable VI+ asics

Seems to work reliably on VI+ except for a few so enable runpm barring
those where baco for runtime power management is not supported.

[rajneesh] Picked https://patchwork.freedesktop.org/patch/335402/ to
enable runtime pm with baco for kfd. Also fixed a checkpatch warning and
added extra checks for VEGA20 and ARCTURUS.

[Why]
PSP added a new return code for revoked receivers (SRM). We need to
handle that so we don't retry hdcp

This is already being handled on windows

[How]
Add the enums to psp interface header and handle them.

Subject: drm/amd/display: no hdcp retry if bksv or ksv list is revoked

[why]
According to the specs when bksv or ksv list fails SRM check,
HDCP TX should abort hdcp immediately.
However with the current code HDCP will be reattampt upto 4 times.

[how]
Add the logic that stop HDCP retry if bksv or ksv list
is revoked.

 programming

[why]
HDCP DTM needs to be aware of the upto date display topology
information in order to validate hardware consistency.

[how]
update HDCP DTM on update_stream_config call.

Subject: drm/powerplay: Ratelimit PP_ASSERT warnings

In certain situations the message could be reported dozens-to-hundreds of
times, based on how often the function is called.
E.g. If MCLK DPM, any calls to get/set MCLK will result in a failure
message, potentially flooding dmesg. Ratelimit the warnings to avoid
this flood.

Subject: drm/amdgpu/display move get_num_odm_splits() into dc_resource.c

It's used by more than just DCN2.0.  Fixes missing symbol when
amdgpu is built without DCN support.

These two things were in one function.  Split into two.  This looks
like it's duplicating some code, but don't worry.  This is is just in
preparation for future changes.

This is intended to have zero functional change and will just make
future patches easier to understand.

Subject: drm/bridge: ti-sn65dsi86: zero is never greater than an unsigned int

When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to
start at index 0 which always contains the value 0.  0 is not a valid
link rate.

This change should have no real effect but is a small cleanup.

Subject: drm/bridge: ti-sn65dsi86: Don't use MIPI variables for DP link

The ti-sn65dsi86 is a bridge from MIPI to DP and thus has two links:
the MIPI link and the DP link.  The two links do not need to have the
same format or number of lanes.  Stop using MIPI variables when
talking about the DP link.

This has zero functional change because:
* currently we are hardcoding the MIPI link as unpacked RGB888 which
  requires 24 bits and currently we are not changing the DP link rate
  from the bridge's default of 8 bits per pixel.
* currently we are hardcoding both the MIPI and DP as being 4 lanes.

This is all in prep for fixing some of the above.

Subject: drm/bridge: ti-sn65dsi86: Config number of DP lanes Mo' Betta

The driver used to say that the value to program into bridge register
0x93 was dp_lanes - 1.  Looking at the datasheet for the bridge, this
is wrong.  The data sheet says:
* 1 = 1 lane
* 2 = 2 lanes
* 3 = 4 lanes

A more proper way to express this encoding is min(dp_lanes, 3).

At the moment this change has zero effect because we've hardcoded the
number of DP lanes to 4.  ...and (4 - 1) == min(4, 3).  How fortunate!
...but soon we'll stop hardcoding the number of lanes.

Subject: drm/bridge: ti-sn65dsi86: Use 18-bit DP if we can

The current bridge driver always forced us to use 24 bits per pixel
over the DP link.  This is a waste if you are hooked up to a panel
that only supports 6 bits per color or fewer, since in that case you
can run at 18 bits per pixel and thus end up at a lower DP clock rate.

Let's support this.

While at it, let's clean up the math in the function to avoid rounding
errors (and round in the correct direction when we have to round).
Numbers are sufficiently small (because mode->clock is in kHz) that we
don't need to worry about integer overflow.

Subject: drm/bridge: ti-sn65dsi86: Group DP link training bits in a function

We'll re-organize the ti_sn_bridge_enable() function a bit to group
together all the parts relating to link training and split them into a
sub-function.  This is not intended to have any functional change and
is in preparation for trying link training several times at different
rates.  One small side effect here is that if link training fails
we'll now leave the DP PLL disabled, but that seems like a sane thing
to do.

until we run out of rates to try.  Basically the algorithm here is to
start at the link rate that is the theoretical minimum and then slowly
bump up until we run out of rates or hit the max rate of the sink.  We
query the sink using a DPCD read.

This is, in fact, important in practice.  Specifically at least one
panel hooked up to the bridge (AUO B116XAK01) had a theoretical min
rate more than 1.62 GHz (if run at 24 bpp) and fails to train at the
next rate (2.16 GHz).  It would train at 2.7 GHz, though.

Subject: drm/bridge: ti-sn65dsi86: Avoid invalid rates

Based on work by Bjorn Andersson <bjorn.andersson@linaro.org>,
Jeffrey Hugo <jeffrey.l.hugo@gmail.com>, and
Rob Clark <robdclark@chromium.org>.

Let's read the SUPPORTED_LINK_RATES and/or MAX_LINK_RATE (depending on
the eDP version of the sink) to figure out what eDP rates are
supported and pick the ideal one.

NOTE: I have only personally tested this code on eDP panels that are
1.3 or older.  Code reading SUPPORTED_LINK_RATES for DP 1.4+ was
tested by hacking the code to pretend that a table was there.

Subject: drm/qxl: replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertenly introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Lockdep says we can't call vmemdup() while having objects reserved
because it needs the mmap semaphore.  So reorder the calls reserve
the objects later.

VBLANK interrupts can be disabled immediately or with a delay, where the

get_vblank_timestamp and enabling vblank_disable_immediate in struct
drm_device. Simplify the code in preparation of the removal of struct
drm_device.get_vblank_timestamp.

Subject: drm: Add get_scanout_position() to struct drm_crtc_helper_funcs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new callback get_scanout_position() reads the current location
of the scanout process. The operation is currently located in struct
drm_driver, but really belongs to the CRTC. Drivers will be converted
in separate patches.

To help with the conversion, the timestamp calculation has been
moved from drm_calc_vbltimestamp_from_scanoutpos() to
drm_crtc_vblank_helper_get_vblank_timestamp_internal(). The helper
function supports the new and old interface of get_scanout_position().
drm_calc_vbltimestamp_from_scanoutpos() remains as a wrapper around
the new function.

Callback functions return the scanout position from the CRTC. The
legacy version of the interface receives the device and pipe index,
the modern version receives a pointer to the CRTC. We keep the
legacy version until all drivers have been converted.

v4:
	* 80-character line fixes
v3:
	* refactor drm_calc_vbltimestamp_from_scanoutpos() to minimize
	  code duplication
	* define types for get_scanout_position() callbacks
v2:
	* fix logical op in drm_calc_vbltimestamp_from_scanoutpos()

From 7fe3f0d15aac6c98a97e6d7086f5a6b7bc4ccae4 Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>

Subject: drm: Add get_vblank_timestamp() to struct drm_crtc_funcs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The callback get_vblank_timestamp() is currently located in struct
drm_driver, but really belongs into struct drm_crtc_funcs. Add an
equivalent there. Driver will be converted in separate patches.

The default implementation is drm_calc_vbltimestamp_from_scanoutpos().
The patch adds drm_crtc_vblank_helper_get_vblank_timestamp(), which is
an implementation for the CRTC callback.

v4:
	* more readable code for setting high_prec (Ville, Jani)
v3:
	* use refactored timestamp calculation to minimize duplicated code
	* do more checks for crtc != NULL to support legacy drivers
v2:
	* rename helper to drm_crtc_vblank_helper_get_vblank_timestamp()
	* replace drm_calc_vbltimestamp_from_scanoutpos() with
	  drm_crtc_vblank_helper_get_vblank_timestamp() in docs

Subject: drm/amdgpu: Convert to struct
 drm_crtc_helper_funcs.get_scanout_position()

The callback struct drm_driver.get_scanout_position() is deprecated in
favor of struct drm_crtc_helper_funcs.get_scanout_position(). Convert
amdgpu over.

Subject: drm/amdgpu: Convert to CRTC VBLANK callbacks

VBLANK callbacks in struct drm_driver are deprecated in favor of
their equivalents in struct drm_crtc_funcs. Convert amdgpu over.

v2:
	* don't wrap existing functions; change signature instead

From 4bbffbf3c19a517625104fd7161c4c23d631351e Mon Sep 17 00:00:00 2001

Subject: drm/i915: Convert to CRTC VBLANK callbacks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VBLANK callbacks in struct drm_driver are deprecated in favor of their
equivalents in struct drm_crtc_funcs. Convert i915 over.

The callback struct drm_driver.get_scanout_position() is deprecated
in favor of struct drm_crtc_helper_funcs.get_scanout_position().
i915 doesn't use CRTC helpers. Instead pass i915's implementation of
get_scanout_position() to DRM core's
drm_crtc_vblank_helper_get_vblank_timestamp_internal().

v3:
	* rename dcrtc to _crtc
	* use intel_ prefix for i915_crtc_get_vblank_timestamp()
	* update for drm_crtc_vblank_helper_get_vblank_timestamp_internal()
v2:
	* use DRM's implementation of get_vblank_timestamp()
	* simplify function names

Subject: drm/vc4: Convert to struct
 drm_crtc_helper_funcs.get_scanout_position()

The callback struct drm_driver.get_scanout_position() is deprecated in
favor of struct drm_crtc_helper_funcs.get_scanout_position(). Convert vc4
over.

Subject: drm: Clean-up VBLANK-related callbacks in struct drm_driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All non-legacy users of VBLANK functions in struct drm_driver have been
converted to use the respective interfaces in struct drm_crtc_funcs. The
remaining users of VBLANK callbacks in struct drm_driver are legacy drivers
with userspace modesetting.

All users of struct drm_driver.get_scanout_position() have been
converted to the respective CRTC helper function. Remove the callback
from struct drm_driver.

There are no users left of get_vblank_timestamp(), so the callback is
being removed. The other VBLANK callbacks are being moved to the legacy
section at the end of struct drm_driver.

Also removed is drm_calc_vbltimestamp_from_scanoutpos(). Callers of this
function have been converted to use the CRTC instead.

v4:
	* more readable code for setting high_prec (Ville, Jani)
v2:
	* merge with removal of struct drm_driver.get_scanout_position()
	* remove drm_calc_vbltimestamp_from_scanoutpos()

Subject: drm: Remove legacy version of get_scanout_position()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The legacy version of get_scanout_position() was only useful while
drivers still used drm_driver.get_scanout_position(). With no such
drivers left, the related typedef and code can be removed

Subject: drm/i915/selftests: Exercise timeslice rewinding

Originally, I did not expect having to rewind a context upon
timeslicing: the point was to replace the executing context with a
non-executing one! However, given a second context that depends on
requests from the first, we may have to split the requests along the
first context to execute the second, causing us to partially replay the
first context and so have to rewind its RING_TAIL.

Subject: drm/i915/hdmi: prefer to_i915() over drm->dev_private to get at i915

drm->dev_private is to be avoided. Use to_i915() on the struct
drm_device pointer instead. Rename the affected local dev_priv variables
to i915 while at it.

Subject: drm/i915: register vga switcheroo later, unregister earlier
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move vga switcheroo and dsm handler register later in
i915_driver_register(), and unregister in i915_driver_unregister(). The
dsm handler unregister is a nop, and is only added for completeness.

My unsubstantiated suspicion is that the vga switcheroo state change
would not work as early as we register the hooks currently. In any case
exposing the interfaces to the world only after we've got everything set
up seems prudent.

Also replace the error handling in vga switcheroo register with a simple
error message. This is done at the same time due to lack of error
propagation from i915_driver_register().

Subject: drm: Add support for DP 1.4 Compliance edid corruption test

Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate
real CRC value of the last edid data block, and write it back.
Current edid CRC calculates routine adds the last CRC byte,
and check if non-zero.

This behavior is not accurate; actually, we need to return
the actual CRC value when corruption is detected.
This commit changes this issue by returning the calculated CRC,
and initiate the required sequence.

Change since v7
- Fix for CI.CHECKPATCH

Change since v6
- Add return check

Change since v5
- Obtain real CRC value before dumping bad edid

Change since v4
- Fix for CI.CHECKPATCH

Change since v3
- Fix a minor typo.

Change since v2
- Rewrite checksum computation routine to avoid duplicated code.
- Rename to avoid confusion.

Change since v1
- Have separate routine for returning real CRC.

Subject: drm/virtio: fix error check

The >= compare op must happen in cpu byte order, doing it in
little endian fails on big endian machines like s390.

Subject: drm/i915: split out display debugfs to a separate file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The i915_debugfs.c has grown more than a little unwieldy. Split out the
display related debugfs code to a file of its own under display/,
initialized with a separate call. No functional changes.

v2:
- Also moved i915_frontbuffer_tracking, i915_gem_framebuffer,
  i915_power_domain_info, i915_dmc_info, i915_ipc_status (Ville)

Subject: drm/sun4i: dsi: Use NULL to signify "no panel"

The continued use of an ERR_PTR to signify "no panel" outside of
sun6i_dsi_attach is confusing because it is a double negative. Because
the connector always reports itself as connected, there is also the
possibility of sending an ERR_PTR to drm_panel_get_modes(), which would
crash.

Solve both of these by only storing the panel pointer if it is valid.

Subject: drm/sun4i: dsi: Allow binding the host without a panel

Currently, the DSI host blocks binding the display pipeline until the
panel is available. This unnecessarily prevents other display outpus
from working, and adds logspam to dmesg when the panel driver is built
as a module (the component master is unsuccessfully brought up several
times during boot).

Flip the dependency, instead requiring the host to be bound before the
panel is attached. The panel driver provides no functionality outside of
the display pipeline anyway.

Since the panel is now probed after the DRM connector, we need a hotplug
event to turn on the connector after the panel is attached.

This has the added benefit of fixing panel module removal/insertion.
Previously, the panel would be turned off when its module was removed.
But because the connector state was hardcoded, nothing knew to turn the
panel back on when it was re-attached. Now, with hotplug events
available, the connector state will follow the panel module state, and
the panel will be re-enabled properly.

Subject: drm/sun4i: dsi: Remove incorrect use of runtime PM

The driver currently uses runtime PM to perform some of the module
initialization and cleanup. This has three problems:

1) There is no Kconfig dependency on CONFIG_PM, so if runtime PM is
   disabled, the driver will not work at all, since the module will
   never be initialized.

2) The driver does not ensure that the device is suspended when
   sun6i_dsi_probe() fails or when sun6i_dsi_remove() is called. It
   simply disables runtime PM. From the docs of pm_runtime_disable():

      The device can be either active or suspended after its runtime PM
      has been disabled.

   And indeed, the device will likely still be active if sun6i_dsi_probe
   fails. For example, if the panel driver is not yet loaded, we have
   the following sequence:

   sun6i_dsi_probe()
      pm_runtime_enable()
      mipi_dsi_host_register()
         of_mipi_dsi_device_add(child)
            ...device_add()...
               __device_attach()
                 pm_runtime_get_sync(dev->parent) -> Causes resume
                 bus_for_each_drv()
                    __device_attach_driver() -> No match for panel
                 pm_runtime_put(dev->parent) -> Async idle request
      component_add()
         __component_add()
            try_to_bring_up_masters()
               try_to_bring_up_master()
                  sun4i_drv_bind()
                     component_bind_all()
                        component_bind()
                           sun6i_dsi_bind() -> Fails with -EPROBE_DEFER
      mipi_dsi_host_unregister()
      pm_runtime_disable()
         __pm_runtime_disable()
            __pm_runtime_barrier() -> Idle request is still pending
               cancel_work_sync()  -> DSI host is *not* suspended!

   Since the device is not suspended, the clock and regulator are never
   disabled. The imbalance causes a WARN at devres free time.

3) The driver relies on being suspended when sun6i_dsi_encoder_enable()
   is called. The resume callback has a comment that says:

      Some part of it can only be done once we get a number of
      lanes, see sun6i_dsi_inst_init

   And then part of the resume callback only runs if dsi->device is not
   NULL (that is, if sun6i_dsi_attach() has been called). However, as
   the above call graph shows, the resume callback is guaranteed to be
   called before sun6i_dsi_attach(); it is called before child devices
   get their drivers attached.

   Therefore, part of the controller initialization will only run if the
   device is suspended between the calls to mipi_dsi_host_register() and
   component_add() (which ends up calling sun6i_dsi_encoder_enable()).
   Again, as shown by the above call graph, this is not the case. It
   appears that the controller happens to work because it is still
   initialized by the bootloader.

   Because the connector is hardcoded to always be connected, the
   device's runtime PM reference is not dropped until system suspend,
   when sun4i_drv_drm_sys_suspend() ends up calling
   sun6i_dsi_encoder_disable(). However, that is done as a system sleep
   PM hook, and at that point the system PM core has already taken
   another runtime PM reference, so sun6i_dsi_runtime_suspend() is
   not called. Likewise, by the time the PM core releases its reference,
   sun4i_drv_drm_sys_resume() has already re-enabled the encoder.

   So after system suspend and resume, we have *still never called*
   sun6i_dsi_inst_init(), and now that the rest of the display pipeline
   has been reset, the DSI host is unable to communicate with the panel,
   causing VBLANK timeouts.

Fix all of these issues by inlining the runtime PM hooks into the
encoder enable/disable functions, which are guaranteed to run after a
panel is attached. This allows sun6i_dsi_inst_init() to be called
unconditionally. Furthermore, this causes the hardware to be turned off
during system suspend and reinitialized on resume, which was not
happening before.

Subject: drm/print: Delete a few unused shouting macros

We want to go over to the new lowercase ones, encourage that a bit
more.

v2: Remove the accidentally included hunk from some WIP branch this
was based on (Jani&Sam).

Subject: drm/edid: Check the number of detailed timing descriptors in the CEA
 ext block
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CEA-861 says :
"d = offset for the byte following the reserved data block.
 If no data is provided in the reserved data block, then d=4.
 If no DTDs are provided, then d=0."

So let's not look for DTDs when d==0. In fact let's just make that
<4 since those values would just mean that he DTDs overlap the block
header. And let's also check that d isn't so big as to declare
the descriptors to live past the block end, although the code
does already survive that case as we'd just end up with a negative
number of descriptors and the loop would not do anything.

Subject: drm/edid: Don't accept any old garbage as a display descriptor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently we assume any 18 byte descriptor to be a display descritor
if only the tag byte matches the expected value. But for detailed
timing descriptors that same byte is just the lower 8 bits of
hblank, and as such can match any display descriptor tag. To
properly validate that the 18 byte descriptor is in fact a
display descriptor we must also examine bytes 0-2 (just byte 1
should actually suffice but the spec does say that bytes 0 and
2 must also always be zero for display descriptors so we check
those too).

Unlike Allen's original proposed patch to just fix is_rb() we
roll this out across the board to fix everything.

After much head scratching I managed to convince myself that
for_each_displayid_db() has already done the bounds checks for
the DispID CEA data block. Which is why we don't need to repeat
them in cea_db_offsets(). To avoid having to go through that
pain again in the future add a comment which explains this fact.

Subject: drm/edid: Add a FIXME about DispID CEA data block revision
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I don't understand what the DispID CEA data block revision
means. The spec doesn't say. I guess some DispID must have
a value of >= 3 in there or else we generally wouldn't
even parse the CEA data blocks. Or does all this code
actually not do anything?

Subject: drm/i915: Ensure no conflicts with BIOS when updating Dbuf

TGL BIOS seems to enable both DBuf slices ocasionally, depending
how many displays are connected, while i915 according to BSpec
was powering on S1 DBuf slice, until a modeset was done.

This was causing a brief flash during the boot as we were
disabling slice, previously used by BIOS with that.

To prevent this, now we are ensuring tht we are enabling
_at least_ one slice, but if there are more, let's not
power them off.

Subject: drm/i915/dsc: force full modeset whenever DSC is enabled at probe

We lack full state readout of DSC config, which may lead to DSC enable
using a config that's all zeros, failing spectacularly. Force full
modeset and thus compute config at probe to get a sane state, until we
implement DSC state readout. Any fastset that did appear to work with
DSC at probe, worked by coincidence. [1] is an example of a change that
triggered the issue on TGL DSI DSC.

Subject: drm/i915: Force state->modeset=true when distrust_bios_wm==true
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently when we load the driver we set distrust_bios_wm=true, which
will cause active_pipe_changes to get flagged even when we're not
toggling any pipes on/off. The reason being that we want to fully
redistribute the dbuf among the active pipes and ignore whatever
state the firmware left behind.

Unfortunately when the code flags active_pipe_changes it doesn't
set state->modeset to true, which means the hardware dbuf state
won't actually get updated. Hence the hardware and software
states go out of sync, which can result in planes trying to use a
disabled dbuf slice. Suprisingly that only seems to corrupt the
display rather than making the whole display engine keel over.

Let's fix this for now by flagging state->modeset whenever
distrust_bios_wm is set.

Eventually we'll likely want to rip out all of this mess and
introduce proper statye tracking for dbuf. But that requires
more work. Toss in a FIXME to that effect.

There was one reference in drm_crtc_helper.c,
which checked if the value was not NULL.
As it was never assigned this check could be dropped.

Subject: drm/pl111: Support Integrator IM-PD1 module

The last in-kernel user of the old framebuffer driver is the
IM-PD1 module for the Integrator/AP. Let's implement support for
this remaining user so we can migrate the last user over to
DRM and delete the old FB driver.

On the Integrator/AP the IM-PD1 system controller will exist
alongside the common Integrator system controller so make
sure to do a special lookup for the IM-PD1 syscon and make it
take precedence if found.

Tested on the Integrator/AP with the IM-PD1 mounted.

Subject: drm/i915: Track hw reported context runtime

GPU saves accumulated context runtime (in CS timestamp units) in PPHWSP
which will be useful for us in cases when we are not able to track context
busyness ourselves (like with GuC). Keep a copy of this in struct
intel_context from where it can be easily read even if the context is not
pinned.

v2:
 (Chris)
 * Do not store pphwsp address in intel_context.
 * Log CS wrap-around.
 * Simplify calculation by relying on integer wraparound.
v3:
 * Include total/avg in traces and error state for debugging

Subject: drm/i915: Avoid potential division-by-zero in computing CS timestamp
 period

Since we use a HW readback or estimation of the CS timestamp frequency,
sometimes it may result in 0. Avoid the division-by-zero in computing
its reciprocal, the timestamp period.

Subject: drm/lima: fix recovering from PLBU out of memory

It looks like on PLBU_OUT_OF_MEM interrupt we need to resume from where we
stopped, i.e. new PLBU heap start is old end. Also update end address
in GP frame to grow heap on 2nd and subsequent out of memory interrupts.

Fixes: 2081e8dcf1ee ("drm/lima: recover task by enlarging heap buffer")

- * Save all Gunit registers that may be lost after a D3 and a subsequent
- * S0i[R123] transition. The list of registers needing a save/restore is
- * defined in the VLV2_S0IXRegs document. This documents marks all Gunit
- * registers in the following way:
- * - Driver: saved/restored by the driver
- * - Punit : saved/restored by the Punit firmware
- * - No, w/o marking: no need to save/restore, since the register is R/O or
- *                    used internally by the HW in a way that doesn't depend
- *                    keeping the content across a suspend/resume.
- * - Debug : used for debugging
- *
- * We save/restore all registers marked with 'Driver', with the following
- * exceptions:
- * - Registers out of use, including also registers marked with 'Debug'.
- *   These have no effect on the driver's operation, so we don't save/restore
- *   them to reduce the overhead.
- * - Registers that are fully setup by an initialization function called from
- *   the resume path. For example many clock gating and RPS/RC6 registers.
- * - Registers that provide the right functionality with their reset defaults.
- *
- * TODO: Except for registers that based on the above 3 criteria can be safely
- * ignored, we save/restore all others, practically treating the HW context as
- * a black-box for the driver. Further investigation is needed to reduce the
- * saved/restored registers even further, by following the same 3 criteria.

+ * - No, w/o marking: no need to save/restore, since the register is R/O or

+ *                    keeping the content across a suspend/resume.
+ * - Debug : used for debugging
+ *
+ * We save/restore all registers marked with 'Driver', with the following
+ * exceptions:
+ * - Registers out of use, including also registers marked with 'Debug'.
+ *   These have no effect on the driver's operation, so we don't save/restore
+ *   them to reduce the overhead.
+ * - Registers that are fully setup by an initialization function called from
+ *   the resume path. For example many clock gating and RPS/RC6 registers.
+ * - Registers that provide the right functionality with their reset defaults.
+ *
+ * TODO: Except for registers that based on the above 3 criteria can be safely

Subject: drm/i915/gt: Rearrange code to silence compiler

Without selftests enabled, I915_SELFTEST_ONLY becomes a dummy,
generating a bare '0'. This causes the compiler to complain about a
useless line, and while we could use I915_SELFTEST_DECLARE instead, it
is a bit messier. Move the selftest-only code to a helper and make that
conditional on having selftests enabled.

Subject: drm/virtio: rework notification for better batching

Drop the virtio_gpu_{disable,enable}_notify().  Add a new
virtio_gpu_notify() call instead, which must be called whenever
the driver wants make sure the host is notified needed.

Drop automatic notification from command submission.  Add
virtio_gpu_notify() calls after each command query instead.
This allows more fine-grained control over host notification
and can move around the notify calls in subsequent patches to
batch command submissions. With this in place it is also
possible to make notification optional for userspace ioctls.

Page flip batching goes away (temporarely).

v3:
 - move batching to separate patches.
v2:
 - rebase to latest drm-misc-next.
 - use "if (!atomic_read())".
 - add review & test tags.

call virtio_gpu_notify() to make sure the host has seen everything
we've submitted.

Subject: drm/virtio: batch display query

Move virtio_gpu_notify() to higher-level functions for
virtio_gpu_cmd_get_display_info() and virtio_gpu_cmd_get_edids().

virtio_gpu_config_changed_work_func() and virtio_gpu_init() will
batch commands and notify only once per update

Subject: drm/i915/gem: use spinlock_t instead of struct spinlock

spinlock_t is one case where the typedef is to be preferred over struct
spinlock.

Subject: drm/i915: split intel_modeset_driver_remove() to pre/post irq
 uninstall
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split intel_modeset_driver_remove() to two, the part with working irqs
before irq uninstall, and the part after irq uninstall. Move
irq_unintall() closer to the layer it belongs.

The error path in i915_driver_modeset_probe() looks obviously weird
after this, but remains as good or broken as it ever was. No functional
changes.

Subject: drm/i915/gt: Refactor l3cc/mocs availability

On dgfx, we only use l3cc and not mocs, but we share the table
containing both register definitions with Tigerlake. This confuses our
selftest that verifies that both sets of registers do contain the values
in our tables after various events (idling, reset, activity etc).

When constructing the table of register definitions, also include the
flags for which registers are valid so that information is computed
centrally and available to all callers.

Read the rawclk_freq during runtime info probing, prior to its first use
in computing the CS timestamp frequency. Then store it in the runtime
info, and include it in the debug printouts.

Subject: drm/i915/selftests: Mark GPR checking more hostile

Currently, we check that a new context has a clear set of general
purpose registers. Add a little bit of hostility by preempting our new
context and re-poisoning the GPR to ensure that there is no context
leakage from preemption.

Subject: drm/amd/display: Don't take the address of skip_scdc_overwrite in
 dc_link_detect_helper

Clang warns:

../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:980:36:
warning: address of 'sink->edid_caps.panel_patch.skip_scdc_overwrite'

1 warning generated.

This is probably not what was intended so remove the address of
operator, which matches how skip_scdc_overwrite is handled in the rest
of the driver.

While we're here, drop an extra newline after this if block.

Subject: drm/i915: Introduce encoder->compute_config_late()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add an optional secondary encoder state compute hook. This gets
called after the normak .compute_config() has been called for
all the encoders in the state. Thus in the new hook we can rely
on all derived state populated by .compute_config() to be already
set up. Should be useful for MST and port sync master/slave
transcoder selection.

Subject: drm/i915/dp: Compute port sync crtc states post compute_config()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch pushes out the computation of master and slave
transcoders in crtc states after encoder's compute_config hook.
This ensures that the assigned master slave crtcs have exact same
mode and timings which is a requirement for Port sync mode
to be enabled.

v3:
* Make crtc_state const, remove crtc state NULL init (Ville)
v2:
* Correct indentation
* Rename to intel_ddi_port_sync_transcoders (Ville)
* remove unwanted debug (Ville)

From 06d63c48dd30b968d2a56e3ece02d6b635cf369a Mon Sep 17 00:00:00 2001
From: Julian Stecklina <julian.stecklina@cyberus-technology.de>

Subject: drm/i915/gvt: make gvt oblivious of kvmgt data structures

Instead of defining KVMGT per-device state in struct intel_vgpu
directly, add an indirection. This makes the GVT code oblivious of
what state KVMGT needs to keep.

The intention here is to eventually make it possible to build
hypervisor backends for the mediator, without having to touch the
mediator itself. This is a first step.

v2:
- rebased onto gvt-staging (no conflicts)

Subject: drm/i915/gt: Protect signaler walk with RCU

While we know that the waiters cannot disappear as we walk our list
(only that they might be added), the same cannot be said for our
signalers as they may be completed by the HW and retired as we process
this request. Ergo we need to use rcu to protect the list iteration and
remember to mark up the list_del_rcu.

v2: Mark the deps as safe-for-rcu

Fixes: 793c22617367 ("drm/i915/gt: Protect execlists_hold/unhold from new waiters")
Fixes: 32ff621fd744 ("drm/i915/gt: Allow temporary suspension of inflight requests")

Timing controllers on A20 are not equivalent: tcon0 on A20 supports
LVDS output and tcon1 does not. Separate the capabilities by
introducing independent set of quirks for each of the tcons.

Subject: drm/i915/debugfs: Pass guc_log struct to i915_guc_log_info

The log struct is the only thing the function needs (apart from
the seq_file), so we can pass just that instead of the whole dev_priv.

v2: Split this change to its own patch (Michal)

In a follow up patch we will rely on the fact that the status always
moves away from "SELECTED" after the fetch is attempted to decide what
to do with the GuC.

Subject: drm/i915/uc: autogenerate uC checker functions

We want to map uC-level checks to GuC/HuC-level ones. The mapping from
the uC state to the GuC/HuC one follows the same pattern for all the
functions:

 uc_xxx_guc() -> guc_is_yyy()

So we can easily use a macro to autogenerate the functions via macros by
passing in the 2 mapped states.

Subject: drm/i915/uc: Improve tracking of uC init status

To be able to setup GuC submission functions during engine init we need
to commit to using GuC as soon as possible.
Currently, the only thing that can stop us from using the
microcontrollers once we've fetched the blobs is a fundamental
error (e.g. OOM); given that if we hit such an error we can't really
fall-back to anything, we can "officialize" the FW fetching completion
as the moment at which we're committing to using GuC.

To better differentiate this case, the uses_guc check, which indicates
that GuC is supported and was selected in modparam, is renamed to
wants_guc and a new uses_guc is introduced to represent the case were
we're committed to using the GuC. Note that uses_guc does still not imply
that the blob is actually loaded on the HW (is_running is the check for
that). Also, since we need to have attempted the fetch for the result
of uses_guc to be meaningful, we need to make sure we've moved away
from INTEL_UC_FIRMWARE_SELECTED.

All the GuC changes have been mirrored on the HuC for coherency.

v2: split fetch return changes and new macros to their own patches,
    support HuC only if GuC is wanted, improve "used" state
    description (Michal)

v3: s/wants_huc/uses_huc in uc_init_wopcm

Subject: drm/i915/uc: Abort early on uc_init failure

Now that we can differentiate wants vs uses GuC/HuC, intel_uc_init is
restricted to running only if we have successfully fetched the required
blob(s) and are committed to using the microcontroller(s).
The only remaining thing that can go wrong in uc_init is the allocation
of GuC/HuC related objects; if we get such a failure better to bail out
immediately instead of wedging later, like we do for e.g.
intel_engines_init, since without objects we can't use the HW, including
not being able to attempt the firmware load.

While at it, remove the unneeded fw_cleanup call (this is handled
outside of gt_init) and add a probe failure injection point for testing.
Also, update the logs for <g/h>uc_init failures to probe_failure() since
they will cause the driver load to fail.

Subject: drm/i915/uc: consolidate firmware cleanup

We are quite trigger happy in cleaning up the firmware blobs, as we do
so from several error/fini paths in GuC/HuC/uC code. We do have the
__uc_cleanup_firmwares cleanup function, which unwinds
__uc_fetch_firmwares and is already called both from the error path of
gem_init and from gem_driver_release, so let's stop cleaning up from
all the other paths.

The fact that we're not cleaning the firmware immediately means that
we can't consider firmware availability as an indication of
initialization success. A "LOADABLE" status has been added to
indicate that the initialization was successful, to be used to
selectively load HuC only if HuC init has completed (HuC init failure
is not considered a fatal error).

v2: s/ready_to_load/loadable (Michal), only run guc/huc_fini if the
    fw is in loadable state

We have a nice little helper to compute a single LUT entry

complete the set.

No point in looping over all connectors for each hpd pin. Just loop
over each connector first and deal with each one's hpd pin. Then
loop over all the hpd pins to mark them as enabled again.

Subject: drm/i915: Mark all HPD capabled connectors as such
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently we only set the DRM_CONNECTOR_POLL_{DISCONNECT,CONNECT}
bits in intel_connector->polled (the base setting), leading to
some confusing looking code to reset drm_connector->polled
(the actual setting) to DRM_CONNECTOR_POLL_HPD. Let's set
intel_connector->polled = DRM_CONNECTOR_POLL_HPD for all hpd
capable connectors, and then we don't need so many special
cases in the hotplug code.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have to write quite a few registers when programming the
pipe scaler. Let's use intel_de_write_fw() for these to reduce
the lockdep overhead a bit. All plane registers (including plane
scaler) already do this.

We already had a few accidental intel_de_write_fw() in there.

Subject: drm/i915: Program MBUS with rmw during initialization

It wasn't terribly clear from the bspec's wording, but after discussion
with the hardware folks, it turns out that we need to preserve the
pre-existing contents of the MBUS ABOX control register when
initializing a few specific bits.

Subject: drm/i915/tgl: Program MBUS_ABOX{1,2}_CTL during display init

On gen11 we only needed to program MBus credits into MBUS_ABOX_CTL
during display initialization, but on gen12 we're now supposed to
program the same values into MBUS_ABOX1_CTL and MBUS_ABOX2_CTL as well.

v2:
 - Program registers with rmw to preserve contents of unrelated bits.
 - Switch to the new display uncore helpers.

Subject: drm/i915/perf: conversion to struct drm_device based logging macros.

Manual conversion of instances of printk based drm logging macros to the
struct drm_device based logging macros in i915/i915_perf.c.
Also involves extraction of the struct drm_i915_private device from
various intel types for use in the macros.

Instances of the DRM_DEBUG printk macro were not converted due to the
lack of an analogous struct drm_device based logging macro.

v2: remove instances of DRM_DEBUG that were converted.

Subject: drm/i915/pmu: Avoid using globals for PMU events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Attempting to bind / unbind module from devices where we have both
integrated and discreete GPU handled by i915, will cause us to try and
double free the global state, hitting null ptr deref in free_event_attributes.

Let's move it to i915_pmu.

Subject: drm/i915: Check that the vma hasn't been closed before we insert it

As there is a delay before we pin a vma, there is an opportunity for
another thread to have closed the vm and its vma (including us).
Check as soon as we acquire the vm->mutex and know the vm/vma is stable.

Upon unregistering the user interface, we mark the GPU as wedged to
ensure we push no new work to the GPU, and to flush all current work
from the GPU. Move this call to the GT backend.

Subject: drm/panel: simple: fix osd070t1718_19ts sync drive edge

The panel datasheet says that the panel samples at falling edge, but
does not say anything about h/v sync signals. Testing shows that if the
sync signals are driven on falling edge, the picture on the panel will
be slightly shifted right.

Setting sync drive edge to the same as data drive edge fixes this issue.

Pair the irq install and uninstall in the same layer. There are no
functional changes in the happy day scenario. The cleanup paths are
currently a mess though.

Note that modeset probe pre-irq + post-irq install are matched by
modeset driver remove pre-irq + post-irq uninstall, together, but not
independently. They are not symmetric pairs.

v2: don't add a new probe failure point here

Subject: drm/i915: Distribute switch variables for initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.

To avoid these problems, move such variables into the "case" where
they're used or lift them up into the main function body.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is
readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/ddi: Make WARN* drm specific where drm_device ptr is
 available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/display: Make WARN* drm specific where drm_device
 ptr is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/power: Make WARN* drm specific where drm_priv ptr is
 available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is
readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/dp: Make WARN* drm specific where drm_device ptr is
 available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/display/hdcp: Make WARN* drm specific where drm_priv ptr is
 available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is
readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Subject: drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is
readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Restore the previous WARN_ON(cond) so that we don't complain about poor
old Cherryview.

Subject: drm/i915: fix header test with GCOV

$(CC) with $(CFLAGS_GCOV) assumes the output filename with .gcno suffix
appended is writable. This is not the case when the output filename is
/dev/null:

  HDRTEST drivers/gpu/drm/i915/display/intel_frontbuffer.h
/dev/null:1:0: error: cannot open /dev/null.gcno
  HDRTEST drivers/gpu/drm/i915/display/intel_ddi.h
/dev/null:1:0: error: cannot open /dev/null.gcno
make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:
drivers/gpu/drm/i915/display/intel_ddi.hdrtest] Error 1
make[5]: *** Waiting for unfinished jobs....
make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:
drivers/gpu/drm/i915/display/intel_frontbuffer.hdrtest] Error 1

Filter out $(CFLAGS_GVOC) from the header test $(c_flags) as they don't
make sense here anyway.

Subject: drm/i915/psr: Force PSR probe only after full initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 60c6a14b489b ("drm/i915/display: Force the state compute phase
once to enable PSR") was forcing the state compute too earlier
causing errors because not everything was initialized, so here
moving to the end of i915_driver_modeset_probe() when the display is
all initialized.

Also fixing the place where it disarm the force probe as during the
atomic check phase errors could happen like the ones due locking and
it would cause PSR to never be enabled if that happens.
Leaving the disarm to the atomic commit phase, intel_psr_enable() or
intel_psr_update() will be called even if the current state do not
allow PSR to be enabled.

v2: Check if intel_dp is null in intel_psr_force_mode_changed_set()
v3: Check intel_dp before get dev_priv
v4:
- renamed intel_psr_force_mode_changed_set() to
intel_psr_set_force_mode_changed()
- removed the set parameter from intel_psr_set_force_mode_changed()
- not calling intel_psr_set_force_mode_changed() from
intel_psr_enable/update(), directly setting it after the same checks
that intel_psr_set_force_mode_changed() does
- moved intel_psr_set_force_mode_changed() arm call to
i915_driver_modeset_probe() as it is a better for a PSR call, all the
functions calls happening between the old and the new function call
will cause issue

Subject: drm/virtio: factor out context create hypercall

We currently create an OpenGL context when opening the DRM fd
if 3D is available.

We may need other context types (VK,..) in the future, and the plan
is to have explicit initialization for that.

For explicit initialization to work, we need to factor out
virtio_gpu_create_context from driver initialization.

v2: Move context handle initialization too (olv)
v6: Remove redundant 3D check (emil.velikov)

Subject: drm/bridge: panel: Propagate bus format/flags

Propagate bus format/flags so that the previous bridge element in the
chain knows which input format the panel bridge expects.

v11:
* Fix a typo in the subject
* Update the commit message so it's readable by itself

v10:
* Add changelog to the commit message

v8 -> v9:
* No changes

v7:
* Set atomic state hooks explicitly

v4 -> v6:
* Not part of the series

v3:
* Adjust things to match the new bus-format negotiation approach
* Use drm_atomic_helper_bridge_propagate_bus_fmt
* Don't implement ->atomic_check() (the core now takes care of bus
  flags propagation)

v2:
* Adjust things to match the new bus-format negotiation approach

1)
we shouldn't load PSP kdb and sys/sos for VF, they are
supposed to be handled by hypervisor

2)
ih reroute doesn't work on VF thus we should avoid calling
it, besides VF should not use those PSP register sets for PF

3)
shouldn't load SMU ucode under SRIOV, otherwise PSP would report
error

some os preemption path is messed up with world switch preemption

fix:
cleanup those logics so os preemption not mixed with world switch

this patch is a general fix for issues comes from SRIOV MCBP, but
there is still UMD side issues not resovlved yet, so this patch
cannot fix all world switch bug.

Subject: drm/amdgpu: Improve Vega20 XGMI TLB flush workaround
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using a heavy-weight TLB flush once is not sufficient. Concurrent
memory accesses in the same TLB cache line can re-populate TLB entries
from stale texture cache (TC) entries while the heavy-weight TLB
flush is in progress. To fix this race condition, perform another TLB
flush after the heavy-weight one, when TC is known to be clean.

Move the workaround into the low-level TLB flushing functions. This way
they apply to amdgpu as well, and KIQ-based TLB flush only needs to
synchronize once.

Subject: drm/amd/display: Add aconnector condition check for dpcd read

[Why]
core_link_read_dpcd() will invoke dm_helpers_dp_read_dpcd(),
which needs to read dpcd info with the help of aconnector.
If aconnector (dc->links[i]->prev) is NULL, then dpcd status
 cannot be read.

As a result, dpcd read fails and a line of error will be
printed out in dmesg.log as:
"*ERROR* Failed to found connector for link!"

[How]
Make sure that aconnector (dc->links[i]->prev) is not NULL,
then read dpcd status.

Subject: drm/amd/display: update scaling filters

Currently there is a minor error in scaling filter coefficients
caused by truncation to fit the HW registers.This error accummulates
with increased taps, but has gone unnoticed due to vast majority of
scaling being done with only 4 taps.

Scaling filters are now updated using HW team's filter generator
which has quantization error minimization built in.

Subject: drm/amd/display: Update TX masks correctly

[Why]
Bugs occur when TX interrupt comes in when no USB-C on board.

[How]
Check PHY for USB-C before enabling TX interrupt in DMCU FW.

Subject: drm/amd/display: Disable PG on NV12

[Why]
According to HW team, PG is dropped for NV12, but programming
the registers will still cause power to be consumed, so don't
program for NV12.

[How]
Set function pointer to NULL if NV12

Subject: drm/amd/display: Wait for DMCUB to finish loading before executing
 commands

[Why]
When we execute the first command for ASIC_INIT for command table
offloading we can hit a timing scenario such that the interrupts
for the inbox wptr haven't been enabled yet and the first command
is ignored until the second command is sent.

[How]
This happens when either the SCRATCH0 is already the correct status
code or autoload check is unsupported.

Clear SCRATCH0 during reset.

Also ensure that we don't accidentally reset the ASIC again in case
of a hang by clearing GPINT while we're at it.

Subject: drm/amd/display: Don't ask PSP to load DMCUB for backdoor load

[Why]
If we're doing backdoor load then do it entirely ourselves without
invoking any of the frontdoor path to avoid potential issues with
outdated tOS.

[How]
Check the load type and don't pass it to base if we don't want it
loaded.

Subject: drm/amd/display: do not force UCLK DPM to stay at highest state
 during display off in DCN2

[Why]
Add optimization to allow pstate change support when all displays
are off in DCN2.

[How]
Add clk_mgr_helper_get_active_plane_cnt() to sum plane_count for all
valid stream_status[].  If plane_count is 0, then there are no active
or virtual streams present. Use plane_count == 0 as extra condition to
enable p_state_change_support in dcn2_update_clocks().

1. evict_vmids() logic was fixed;
2. Added boundary check for add_ptb_to_table() and
   clear_entry_from_vmid_table() to avoid crash caused by array out of
   boundary;
3. For mod_vmid_get_for_ptb(), vimd is changed from unsigned to signed
   due to vimd is signed.

[Why]
Currently DAL programs negative slope for the last point of output
transfer function curve.

[How]
Applying a check for the last PWL point for RGB values not to be
smaller than previous. If smaller, initialize the last point values
to a sum of previous PWL value and previous PWL delta;

Subject: drm/amd/display: Add DMUB firmware state debugfs

[Why]
Firmware state helps to debug sequence issues and hangs for DMCUB
commands and we don't have an easy mechanism to dump it from the driver.

[How]
Add a debugfs entry to dump the current firmware state.
Example usage:

cat /sys/kernel/debug/dri/0/amdgpu_dm_dmub_fw_state

Subject: drm/amd/display: Workaround required for link training reliability

[Why]
A software workaround is required for all vendor-built cards on platform.

[How]
When performing DP link training, we must send TPS1 before DPCD:100h is
written with the proper bit rate value. This change must be applies in
ALL cases when LT happens.

Subject: drm/amd/display: Monitor patch to delay setting ignore MSA bit

[Why]
Some displays clear ignore MSA bit on mode change, which cause
blackscreen when programming variable vtotals. Ignore MSA bit needs
programming needs to be delayed or re-set to be retained.

[How]
Create patch to delay programming ignore MSA bit after unblanking
stream.

Subject: drm/amd/display: Fix RV2 Variant Detection

[WHY]
RV2 and variants are indistinguishable by hw internal rev alone, need to
be distinguishable in order to correctly set max vlevel.  Previous
detection change incorrectly checked for hw internal rev.

[HOW]
Use pci revision to check if RV2 or low power variant Correct a few
overlapping ASICREV range checks

Subject: drm/amd/display: Update TTU properly

[Why]
We need to update TTU properly if DRAMClockChangeWatermark changes. If
TTU < DRAMClockChangeWatermark, we pstate won't be allowed and we will
hang in some PSR cases.

[How]
Update TTU if DramClockChangeWatermark value increases (only if TTU was
dependent on the watermark value on the DRAMClockChangeWatermark value
in the first place).

From 89e94bc57429305e089f149a6e7083e5f36f39c4 Mon Sep 17 00:00:00 2001

Subject: drm/amd/display: optimize prgoram wm and clks

[Why]
In some display configuration like 1080P monitor playing a 1080P video,
if user use ALT+F4 to exit Movie and TV, there is a chance clocks are
same only water mark changed. Current clock optimization machanism will
result in water mark keeps high after exit Movie and TV app.

[How]
Return if watermark need to be optimized when doing program watermark,
perform the optimization after.

Subject: drm/amd/display: Make clock table struct more accessible

[WHY]
Currently clock table struct is very far down in the bounding box struct
making it hard to find while debugging, especially when using the
dal3dbgext.

[HOW]
Move it up so it is the first struct defined, and therefore much easier
to find and access.

Subject: drm/amd/display: Temporarily disable stutter on MPO transition

[Why]
Underflow sometimes occurs during transition into MPO with stutter
enabled.

[How]
When transitioning into MPO, disable stutter. Re-enable stutter within
one frame.

Subject: drm/amd/display: limit display clock to 100MHz to avoid FIFO error

[Why]
when changing display clock, SMU need to use power up DFS and use
DENTIST to ramp DFS DID to switch target frequency before switching back
to bypass.

[How]
fixed the minimum display clock to 100MHz, it's W/A the same with PCO.

Subject: drm/i915: Flush idle barriers when waiting

If we do find ourselves with an idle barrier inside our active while
waiting, attempt to flush it by emitting a pulse using the kernel
context.

No good reason why we must always use a static ringsize, so let
userspace select one during construction.

Subject: drm/i915/gem: Honour O_NONBLOCK before throttling execbuf submissions

Check the user's flags on the struct file before deciding whether or not
to stall before submitting a request. This allows us to reasonably
cheaply honour O_NONBLOCK without checking at more critical phases
during request submission.

Subject: drm/panfrost: Add support for multiple regulators

Some GPUs, namely, the bifrost/g72 part on MT8183, have a second
regulator for their SRAM, let's add support for that.

We extend the framework in a generic manner so that we could
support more than 2 regulators, if required.

Subject: drm/panfrost: Add support for multiple power domains

When there is a single power domain per device, the core will
ensure the power domain is switched on (so it is technically
equivalent to having not power domain specified at all).

However, when there are multiple domains, as in MT8183 Bifrost
GPU, we need to handle them in driver code.

Subject: drm/i915: split intel_modeset_init() to pre/post irq install
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split inte_modeset_init() to parts before and after irq install, to
facilitate further cleanup. The error paths are a mess, otherwise no
functional changes.

Subject: drm/connector: Add helper to get a connector type name

drm_connector.c contains a map of connector types (DRM_MODE_CONNECTOR_*)
to name strings, but doesn't expose it. This leads to drivers having to
store a similar map.

Add a new drm_get_connector_type_name() helper function that return a
name string for a connector type.

The drm_display_info structure contains many fields related to HDMI

shall be treated as an HDMI sink or a DVI sink. Add such a flag, and
populate it according to section 8.3.3 ("DVI/HDMI Device

Subject: drm/bridge: Add connector-related bridge operations and data

To support implementation of DRM connectors on top of DRM bridges
instead of by bridges, the drm_bridge needs to expose new operations and
data:

- Output detection, hot-plug notification, mode retrieval and EDID
  retrieval operations
- Bitmask of supported operations
- Bridge output type
- I2C adapter for DDC access

Add and document these.

Three new bridge helper functions are also added to handle hot plug
notification in a way that is as transparent as possible for the
bridges.

+ * - The connector-related operations support implementing a &drm_connector

+ *   requires all operations of the &drm_connector to be handled by a single
+ *   bridge, which doesn't always match the hardware architecture.
+ *
+ *   To simplify bridge drivers and make the connector implementation more
+ *   flexible, a new model allows bridges to unconditionally skip creation of
+ *   &drm_connector and instead expose &drm_bridge_funcs operations to support
+ *   an externally-implemented &drm_connector. Those operations are
+ *   &drm_bridge_funcs.detect, &drm_bridge_funcs.get_modes,

+ *   the features that the bridge hardware support. For instance, if a bridge
+ *   supports reading EDID, the &drm_bridge_funcs.get_edid shall be
+ *   implemented. This however doesn't mean that the DDC lines are wired to the
+ *   bridge on a particular platform, as they could also be connected to an I2C
+ *   controller of the SoC. Support for the connector-related operations on the
+ *   running platform is reported through the &drm_bridge.ops flags. Bridge
+ *   drivers shall detect which operations they can support on the platform
+ *   (usually this information is provided by ACPI or DT), and set the
+ *   &drm_bridge.ops flags for all supported operations. A flag shall only be
+ *   set if the corresponding &drm_bridge_funcs operation is implemented, but
+ *   an implemented operation doesn't necessarily imply that the corresponding
+ *   flag will be set. Display drivers shall use the &drm_bridge.ops flags to
+ *   decide which bridge to delegate a connector operation to. This mechanism
+ *   allows providing a single static const &drm_bridge_funcs instance in
+ *   bridge drivers, improving security by storing function pointers in

Subject: drm/bridge: Add interlace_allowed flag to drm_bridge

In preparation for a connector creation helper based on a chain of
bridges, add a flag to the drm_bridge structure to report support for
interlaced modes. This will be used to set the connector's
interlace_allowed flag.

Subject: drm/bridge: Extend bridge API to disable connector creation

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:

- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.

- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.

- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).

In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).

Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.

The change is based on the following semantic patch, with manual review
and edits.

Subject: drm/bridge: dumb-vga-dac: Rename internal symbols to simple-bridge

The dumb-vga-dac driver is a simple DRM bridge driver for simple VGA
DACs that don't require configuration. Other non-VGA bridges fall in a
similar category, and would benefit from a common driver. Prepare for
this by renaming the internal symbols from dumb-vga-dac to
simple-bridge.

Subject: drm/bridge: simple-bridge: Add support for non-VGA bridges

Create a new simple_bridge_info structure that stores information about
the bridge model, and store the bridge timings in there, along with the
connector type. Use that new structure for of_device_id data. This
enables support for non-VGA bridges.

Subject: drm/bridge: Add bridge driver for display connectors

Display connectors are modelled in DT as a device node, but have so far
been handled manually in several bridge drivers. This resulted in
duplicate code in several bridge drivers, with slightly different (and
thus confusing) logics.

In order to fix this, implement a bridge driver for display connectors.
The driver centralises logic for the DVI, HDMI, VGAn composite and
S-video connectors and exposes corresponding bridge operations.

This driver in itself doesn't solve the issue completely, changes in
bridge and display controller drivers are needed to make use of the new
connector driver.

Subject: drm/bridge: tfp410: Replace manual connector handling with bridge

Now that a driver is available for display connectors, replace the
manual connector handling code with usage of the DRM bridge API. The
tfp410 driver doesn't deal with the display connector directly anymore,
but still delegates drm_connector operations to the next bridge. This
brings us one step closer to having the tfp410 driver handling the
TFP410 only.

Subject: drm/bridge: tfp410: Allow operation without drm_connector

The tfp410 driver can operate as part of a pipeline where the
drm_connector is created by the display controller. Enable this mode of
operation by skipping creation of a drm_connector internally.

Subject: drm: Add helper to create a connector for a chain of bridges

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:

- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.

- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.

- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).

In order to solve these issues, ownership of the connector needs to be
moved to the display controller driver.

To avoid code duplication in display controller drivers, add a new
helper to create and manage a DRM connector backed by a chain of
bridges. All connector operations are delegating to the appropriate
bridge in the chain.

+/**
+ * DOC: overview
+ *
+ * The DRM bridge connector helper object provides a DRM connector
+ * implementation that wraps a chain of &struct drm_bridge. The connector
+ * operations are fully implemented based on the operations of the bridges in
+ * the chain, and don't require any intervention from the display controller
+ * driver at runtime.
+ *
+ * To use the helper, display controller drivers create a bridge connector with
+ * a call to drm_bridge_connector_init(). This associates the newly created
+ * connector with the chain of bridges passed to the function and registers it
+ * with the DRM device. At that point the connector becomes fully usable, no
+ * further operation is needed.
+ *
+ * The DRM bridge connector operations are implemented based on the operations
+ * provided by the bridges in the chain. Each connector operation is delegated
+ * to the bridge closest to the connector (at the end of the chain) that
+ * provides the relevant functionality.
+ *
+ * To make use of this helper, all bridges in the chain shall report bridge
+ * operation flags (&drm_bridge->ops) and bridge output type
+ * (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach
+ * flag (none of the bridges shall create a DRM connector directly).

Subject: drm/omap: dss: Cleanup DSS ports on initialisation failure

When the DSS initialises its output DPI and SDI ports, failures don't
clean up previous successfully initialised ports. This can lead to
resource leak or memory corruption. Fix it.

Replace the manual panel handling code by a drm_panel_bridge. This
simplifies the driver and allows all components in the display pipeline
to be treated as bridges, paving the way to generic connector handling.

Subject: drm/omap: dss: Fix output next device lookup in DT

The DSS core looks up the next device connected to an output by
traversing the OF graph. It currently hardcodes the local port number to
0, which breaks any output with a different port number (SDI on OMAP3
and any DPI output but the first one). Fix this by repurposing the
currently unused of_ports bitmask in omap_dss_device with an of_port
output port number, and use it to traverse the OF graph.

Subject: drm/omap: Add infrastructure to support drm_bridge local to DSS
 outputs

In order to support drm_bridge-based pipeline, the internal HDMI
encoders will need to expose the EDID read operation through the
drm_bridge API, and thus to expose a drm_bridge instance corresponding
to the encoder. The HDMI encoders are however handled as omap_dss_device
instances, which conflicts with this requirement.

In order to move forward with the drm_bridge transition, add support for
creating drm_bridge instances local to DSS outputs. If a local bridge is
passed to the omapdss_device_init_output() function, it is used as the
first bridge in the chain, and the omap_dss_device.next_bridge field is
set to the next bridge for the use of the internal encoders' bridges.

Subject: drm/omap: dss: Make omap_dss_device_ops optional

As part of the move to drm_bridge ops, the dssdev ops will become empty
for some of the internal encoders. Make them optional in the driver to
allow them to be removed completely, easing the transition.

Subject: drm/omap: hdmi4: Rework EDID read to isolate data read

In preparation of adding DRM bridge support to the hdmi4 encoder code,
rework the EDID read to isolate data read.

The hdmi_read_edid() function is the main entry point. It performs all
initialisation steps required prior to reading the EDID (such as
ensuring the device is powered on), as well as corresponding cleanup
steps afterwards. EDID read itself is handled by hdmi_read_edid_data()
that calls the hdmi4_core_ddc_read() function to read individual blocks.

This new code architecture will allow reusing hdmi_read_edid() and
hdmi4_core_ddc_read() for the drm_bridge EDID read implementation, while
swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid()
function.

Subject: drm/omap: hdmi5: Rework EDID read to isolate data read

In preparation of adding DRM bridge support to the hdmi5 encoder code,
rework the EDID read to isolate data read.

The hdmi_read_edid() function is the main entry point. It performs all
initialisation steps required prior to reading the EDID (such as
ensuring the device is powered on), as well as corresponding cleanup
steps afterwards. EDID read itself is handled by hdmi_read_edid_data()
that calls the hdmi5_core_ddc_read() function to read individual blocks.

This new code architecture will allow reusing hdmi_read_edid() and
hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while
swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid()
function.

Subject: drm/omap: hdmi4: Register a drm_bridge for EDID read

In order to integrate with a chain of drm_bridge, the internal HDMI4
encoder has to expose the EDID read operation through the drm_bridge
API. Register a bridge at initialisation time to do so.

For the time being make the next bridge in the chain optional as the
HDMI output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.

Subject: drm/omap: hdmi5: Register a drm_bridge for EDID read

In order to integrate with a chain of drm_bridge, the internal HDMI5
encoder has to expose the EDID read operation through the drm_bridge
API. Register a bridge at initialisation time to do so.

For the time being make the next bridge in the chain optional as the
HDMI output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.

Subject: drm/omap: hdmi4: Move mode set, enable and disable operations to
 bridge

Move the omap_dss_device .set_timings(), .enable() and .disable()
operations to the drm_bridge functions. As the drm_bridge for the HDMI
encoder is unconditionally registered and attached, those operations
will be called at the appropriate time.

The omapdss device .set_infoframe() and .set_hdmi_mode() operations have
no equivalent in drm_bridge. Thir content is thus moved to the bridge
.enable() operation as the data they store is not needed before the HDMI
encoder gets enabled.

Subject: drm/omap: venc: Register a drm_bridge

In order to integrate with a chain of drm_bridge, the internal VENC
encoder has to expose the mode valid, fixup and set, the enable and
disable and the get modes operations through the drm_bridge API.
Register a bridge at initialisation time to do so.

Most of those operations are removed from the omap_dss_device as they
are now called through the drm_bridge API by the DRM atomic helpers. The
only exception is the .get_modes() operation that is still invoked
through the omap_dss_device-based pipeline.

For the time being make the next bridge in the chain optional as the
VENC output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.

Subject: drm/omap: Create connector for bridges

Use the drm_bridge_connector helper to create a connector for pipelines
that use drm_bridge. This allows splitting connector operations across
multiple bridges when necessary, instead of having the last bridge in
the chain creating the connector and handling all connector operations
internally.

Subject: drm/omap: Switch the HDMI and VENC outputs to drm_bridge

The TPD12S015, OPA362 and analog and HDMI connectors are now supported
by DRM bridge drivers, and the omapdrm HDMI and VENC outputs can be
handled through the drm_bridge API. Switch the outputs to drm_bridge by
making the next bridge mandatory and removing the related
omapdrm-specific display drivers.

From 75fb968b83d0530e2be2cb51e90b7bc849dd433b Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Wed, 26 Feb 2020 13:25:00 +0200
Subject: drm/omap: Remove HPD, detect and EDID omapdss operations

Due to the removal of several omapdrm display drivers, the omapdss HPD,
detected and EDID operations are not used anymore. Remove them and all
related code.

The dpi_set_pll_clk() and dpi_set_dispc_clk() return various information
through pointer arguments that are never used by the callers. Remove
them to simplify the clock setting API.

Subject: drm/omap: dpi: Register a drm_bridge

In order to integrate with a chain of drm_bridge, the internal DPI
output has to expose its operations through the drm_bridge API.
Register a bridge at initialisation time to do so and remove the
omap_dss_device operations that are now unused.

Subject: drm/i915: Iterate over pipes and skip the disabled one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It should not be assumed that a disabled display pipe will be
always last the pipe.
for_each_pipe() should iterate over I915_MAX_PIPES and check
for the disabled pipe and skip that pipe so that it should not
initialize the intel crtc for any disabled pipes.

Due to changes in for_each_pipe() macro, it requires to handle
the below compilation error.
"suggest explicit braces to avoid ambiguous ‘else’
[-Werror=dangling-else]"

v2:
- Cosmetic changes, removed unwanted parentheses. [Ville]

Subject: drm/i915: Remove (pipe == crtc->index) assumption
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

we can't have (pipe == crtc->index) assumption in
driver in order to support 3 non-contiguous
display pipe system.

FIXME: Remove the WARN_ON(drm_crtc_index(&crtc->base) != crtc->pipe)
when we will fix all such assumption.

changes since RFC:
- Added again removed (pipe == crtc->index) WARN_ON.
- Pass drm_crtc_index instead of intel pipe in order to
  call drm_handle_vblank().
v2:
- Used drm_crtc_handle_vblank()/drm_crtc_wait_one_vblank()
  instead of drm_handle_vblank/drm_wait_one_vblank(). [Jani]
- Introduced intel_handle_vblank() helper to avoid sprinkle
  of intel_crtc across irq_handlers. [Ville]
v3:
- Moved intel_handle_vblank() from header to i915_irq.c. [Ville]

Skip the transcoder whose pipe is disabled while

display pipe system.

v2:
- Don't skip EDP_TRANSCODER error state. [Ville]
- Use a helper has_transcoder(). [Ville]
v3:
- Removed DSI transcoder case from has_transcoder(),
  and few other cosmetic changes. [Ville]

Content-Transfer-Encoding: 8bit

intel_plane_fb_max_stride should return the max stride of
primary plane for first available pipe in intel device info
pipe_mask.
Similarly glk_force_audio_cdclk() should also use the first
available CRTC instead of pipe 'A' crtc to force the cdclk
changes.

changes since RFC:
- Introduced a helper to get first intel_crtc intel_get_first_crtc. [Ville]
v1:
- Used intel_get_first_crtc() instead of PIPE_A crtc in
  glk_force_audio_cdclk(). [Ville]

Use ~0U as marker for 'I do not care'. I am not sure what
GC7000 based devices are in the wild and I do not want to
break them. In the near future we should extend the hwdb.

Subject: drm/amdgpu: Remove kfd eviction fence before release bo (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No need to trigger eviction as the memory mapping will not be used
anymore.

All pt/pd bos share same resv, hence the same shared eviction fence.
Everytime page table is freed, the fence will be signled and that cuases
kfd unexcepted evictions.

v2: squash in 32 bit fix

Subject: drm/amdgpu: update psp firmwares loading sequence V2

For those ASICs with DF Cstate management centralized to PMFW,
TMR setup should be performed between pmfw loading and other
non-psp firmwares loading.

V2: skip possible SMU firmware reloading

Subject: drm/amdgpu: add VM update fences back to the root PD v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add update fences to the root PD while mapping BOs.

Otherwise PDs freed during the mapping won't wait for
updates to finish and can cause corruptions.

v2: rebased on drm-misc-next

    drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev

No idea whether this was intentional or accidental breakage, but I
guess anyone who manages to boot a this modern gpu behind an agp
bridge deserves a price. A price I never expect anyone to ever collect
:-)

Subject: drm/radeon: Inline drm_get_pci_dev
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It's the last user, and more importantly, it's the last non-legacy
user of anything in drm_pci.c.

The only tricky bit is the agp initialization. But a close look shows
that radeon does not use the drm_agp midlayer (the main use of that is
drm_bufs for legacy drivers), and instead could use the agp subsystem
directly (like nouveau does already). Hence we can just pull this in
too.

A further step would be to entirely drop the use of drm_device->agp,
but feels like too much churn just for this patch.

Subject: drm/amdgpu: Fix check for DPM when returning max clock

pp_funcs may not exist, while dpm may be enabled. This change ensures
that KFD topology will report the same as pp_dpm_sclk, as the conditions
for reporting them will be the same.

Otherwise, we may see the issue where KFD reports "100MHz" in topology
as the max speed, while DPM is working correctly.

Subject: drm/amdkfd: Delete unnecessary unmap queue package submissions

The previous way of using SDMA queue count to infer whether we should unmap
SDMA engines has bugs. The reason it did not cause issues is because MEC
firmware unmaps all queues (CP + SDMA) when a unmap package for compute
engine is received. Becasue of that, only one unmap queue package
is needed, instead of one unmap queue package for CP and each SDMA engine,
which results in much simpler driver code.

Subject: drm/amdgpu/display: clean up hdcp workqueue handling

Use the existence of the workqueue itself to determine when to
enable HDCP features rather than sprinkling asic checks all over
the code.  Also add a check for the existence of the hdcp
workqueue in the irq handling on the off chance we get and HPD
RX interrupt with the CP bit set.  This avoids a crash if
the driver doesn't support HDCP for a particular asic.

Fixes: 96a3b32e67236f ("drm/amd/display: only enable HDCP for DCN+")

Subject: drm/amdgpu: Increase timout on emulator to tenfold instead of twice

Since emulators are slower, sometime some operations like flushing tlb
through FM need more than twice the regular timout of 100ms, so increase
the timeout to 1s on emulators.

Subject: drm/amdgpu/display: split dp connector registration (v4)

Split into init and register functions to avoid a segfault
in some configs when the load/unload callbacks are removed.

v2:
- add back accidently dropped has_aux setting
- set dev in late_register

v3:
- fix dp cec ordering

v4:
- squash in kdev reference fix

Subject: drm/i915/tgl: Add Wa_1606054188:tgl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Tiger Lake we do not support source keying in the pixel formats P010,
P012, P016.

v2: Move WA to end of function. Create helper function for format
check. Less verbose debugging messaging.

v3: whitespace

v4(MattR):
 - Actually return EINVAL to reject this combination.
 - Pass format parameter as u32.
 - Make test TGL-specific for now.
 - Switch to per-device logging.
 - Shorten/simplify comment.

Subject: drm/i915: split out intel_dram.[ch] from i915_drv.c

The DRAM related routines are pretty isolated from the rest of the
i915_drv.c, split it out to a separate file. Put the eDRAM stuff in the
same bag, and rename the visible functions to have intel_dram_
prefix. Do some benign whitespace fixes and dev_priv -> i915 conversions
while at it.

Subject: drm/i915/dram: use intel_uncore_*() functions for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding uncore register accessors
intel_uncore_read(), intel_uncore_write(), intel_uncore_posting_read(),
intel_uncore_read_fw(), and intel_uncore_write_fw().

Rename dev_priv to i915 while at it.

No functional changes.

Subject: drm/i915/drv: use intel_uncore_write() for register access

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace the sole remaining I915_WRITE() in i915_drv.c with
intel_uncore_write(), although it might be better to keep the entire
file void of direct register access.

No functional changes.

Subject: drm/virtio: add virtio_gpu_is_shmem helper

The plan is use have both shmem and virtual "vram" running
side-by-side in virtio-gpu. It looks like we'll eventually use
struct drm_gem_object as a base class, and we'll need to convert
to shmem and vram objects on the fly. As a first step, add a
virtio_gpu_is_shmem helper. Thanks to kraxel for suggesting this
approach on Gitlab.

Subject: dma-buf: add dynamic DMA-buf handling v15
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On the exporter side we add optional explicit pinning callbacks. Which are
called when the importer doesn't implement dynamic handling, move notification
or need the DMA-buf locked in place for its use case.

On the importer side we add an optional move_notify callback. This callback is
used by the exporter to inform the importers that their mappings should be
destroyed as soon as possible.

This allows the exporter to provide the mappings without the need to pin
the backing store.

v2: don't try to invalidate mappings when the callback is NULL,
    lock the reservation obj while using the attachments,
    add helper to set the callback
v3: move flag for invalidation support into the DMA-buf,
    use new attach_info structure to set the callback
v4: use importer_priv field instead of mangling exporter priv.
v5: drop invalidation_supported flag
v6: squash together with pin/unpin changes
v7: pin/unpin takes an attachment now
v8: nuke dma_buf_attachment_(map|unmap)_locked,
    everything is now handled backward compatible
v9: always cache when export/importer don't agree on dynamic handling
v10: minimal style cleanup
v11: drop automatically re-entry avoidance
v12: rename callback to move_notify
v13: add might_lock in appropriate places
v14: rebase on separated locking change
v15: add EXPERIMENTAL flag, some more code comments

Instead use the pin() callback to detect dynamic DMA-buf handling.
Since amdgpu is now migrated it doesn't make much sense to keep
the extra flag.

This register was placed in the middle of the PP_STATUS definition
instead of together with the PP_CONTROL where it should. Since it's not
used and there are no current plans to use it, just remove the
definition.

v2: remove the define rather than moving it.

Looks like the pipe rounding mode bit has moved from PIPE_CHICKEN to
PIPE_MISC on tgl. Frob the new location.

Bspec does still document the old bits as well, so I left the code
for them as is until we get clarification from the hw folks on
whether the old bits still do something useful.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2
register. We can't read it back either from CPU or GPU. Since the other
bits should be 0, recommendation to handle Wa_1604555607 is to actually
just write the timer value.

Do a write only and don't try to read it, neither before or after
the WA is applied.

Subject: drm/i915/ggtt: do not set bits 1-11 in gen12 ptes

On TGL, bits 2-4 in the GGTT PTE are not ignored anymore and are
instead used for some extra VT-d capabilities. We don't (yet?) have
support for those capabilities, but, given that we shared the pte_encode
function betweed GGTT and PPGTT, we still set those bits to the PPGTT
PPAT values. The DMA engine gets very confused when those bits are
set while the iommu is enabled, leading to errors. E.g. when loading
the GuC we get:

[    9.796218] DMAR: DRHD: handling fault status reg 2
[    9.796235] DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear
[    9.899215] [drm:intel_guc_fw_upload [i915]] *ERROR* GuC firmware signature verification failed

To fix this, just have dedicated gen8_pte_encode function per type of
gtt. Also, explicitly set vm->pte_encode for gen8_ppgtt, even if we
don't use it, to make sure we don't accidentally assign it to the GGTT
one, like we do for gen6_ppgtt, in case we need it in the future.

Subject: drm/i915: Skip barriers inside waits

Attaching to the i915_active barrier is a two stage process, and a flush
is only effective when the barrier is activation. Thus it is possible
for us to see a barrier, and attempt to flush, only for our flush to
have no effect. As such, before attempting to activate signaling on the
fence we need to double check it is a fence!

Subject: drm/i915/selftests: Disable heartbeat around manual pulse tests

Still chasing the mystery of the stray idle flush, let's ensure that the
heartbeat does not run at the same time as our test and confuse us.

Subject: drm/i915/gt: Check engine-is-awake on reset later

As we drop the engine-pm on retiring, that may happen while there are
still CS events in the buffer. As such we cannot assert the engine is
still active on reset, until we know that the current request is still
in flight.

Fix the warnings that show up with W=1.
They are all about unused but set variables.

Subject: drm/i915/gt: Pull marking vm as closed underneath the vm->mutex

Pull the final atomic_dec of vm->open (marking the vm as closed)
underneath the same vm->mutex as used to close it. This is required to
correctly serialise with attempting to reuse the vma as the vm is closed
by a second thread.

Subject: drm/tidss: dispc: Fix broken plane positioning code

The old implementation of placing planes on the CRTC while configuring
the planes was naive and relied on the order in which the planes were
configured, enabled, and disabled. The situation where a plane's zpos
was changed on the fly was completely broken. The usual symptoms of
this problem was scrambled display and a flood of sync lost errors,
when a plane was active in two layers at the same time, or a missing
plane, in case when a layer was accidentally disabled.

The rewrite takes a more straight forward approach when HW is
concerned. The plane positioning registers are in the CRTC (or
actually OVR) register space and it is more natural to configure them
in a one go when configuring the CRTC. To do this we need make sure we
have all the planes on the updated CRTCs in the new atomic state. The
untouched planes on CRTCs that need plane position update are added to
the atomic state in tidss_atomic_check().

Subject: drm/tidss: Drop pointless static qualifier in dispc_find_csc()

There is no need to have the 'const struct dispc_csc_coef *coef'
variable static since new value always be assigned before use it.

Subject: drm/i915/selftests: Verify LRC isolation

Record the LRC registers before/after a preemption event to ensure that
the first context sees nothing from the second client; at least in the
normal per-context register state.

Subject: drm/i915/selftests: Check recovery from corrupted LRC

Check that we can recover if the LRC is totally corrupted. Based on a
very simple theory that anything that can be adjusted via the context
(i.e. on behalf of the user), should be under the purview of the
per-engine-reset.

Subject: drm/i915: Protect i915_request_await_start from early waits

We need to be extremely careful inside i915_request_await_start() as it
needs to walk the list of requests in the foreign timeline with very
little protection. As we hold our own timeline mutex, we can not nest
inside the signaler's timeline mutex, so all that remains is our RCU
protection. However, to be safe we need to tell the compiler that we may
be traversing the list only under RCU protection, and furthermore we
need to start declaring requests as elements of the timeline from their
construction.

Fixes: 9ddc8ec027a3 ("drm/i915: Eliminate the trylock for awaiting an earlier request")
Fixes: 6a79d848403d ("drm/i915: Lock signaler timeline while navigating")

Subject: drm/i915: Fix wrongly populated plane possible_crtcs bit mask
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As a disabled pipe in pipe_mask is not having a valid intel crtc,
driver wrongly populates the possible_crtcs mask while initializing
the plane for a CRTC. Fixing up the plane possible_crtcs mask.

changes since RFC:
- Simplify the possible_crtcs initialization. [Ville]
v2:
- Removed the unnecessary stack garbage possible_crtcs to
  drm_universal_plane_init. [Ville]
v3:
- Combine the intel_crtc assignment and declaration. [Ville]
v4:
- Fix possible_crtcs abused bits from
  intel_{primary,curosr,sprite}_plane_create(). [Ville]

Subject: drm/i915/perf: Mark up the racy use of perf->exclusive_stream

Inside the general i915_oa_init_reg_state() we avoid using the
perf->mutex. However, we rely on perf->exclusive_stream being valid to
access at that point, and for that we have to control the race with
disabling perf. This relies on the disabling being a heavy barrier that
inspects all active contexts, after marking the perf->exclusive_stream
as not available. This should ensure that there are no more concurrent
accesses to the perf->exclusive_stream as we destroy it.

Mark up the races around the perf->exclusive_stream so that they stand
out much more. (And hopefully we will be running kcsan to start
validating that the only races we have are carefully controlled.)

Subject: drm/i915: Add glk to intel_detect_preproduction_hw()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Detect GLK pre-production steppings. Not 100% of A2 being pre-prod
since the spec is a bit of a mess but feels more or less correct.

Subject: drm/i915/selftests: Be a little more lenient for reset workers

Give the reset worker a kick before losing help when waiting for hang
recovery, as the CPU scheduler is a little unreliable.

Subject: drm/i915/gt: Reset queue_priority_hint after wedging

An odd and highly unlikely path caught us out. On delayed submission
(due to an asynchronous reset handler), we poked the priority_hint and
kicked the tasklet. However, we had already marked the device as wedged
and swapped out the tasklet for a no-op. The result was that we never
cleared the priority hint and became upset when we later checked.

Subject: drm/amdkfd: change SDMA MQD memory type

SDMA MQD memory type is NC that causes MQD data overwritten
accidentally by an old stable cache line. Changing it to UC
default for GART will fix the issue.

The mqd_gfx9 parameter is meant for control stacks that are
allocated together with user mode queue MQDs. Setting
mqd_gfx9 to true maps the control stack pages as NC.
Here it was accidentally applied to SDMA MQDs,
which are allocated together with the HIQ MQD. Setting
the mqd_gfx9 to false avoids that.

Subject: drm/amdgpu: Initialize SPM_VMID with 0xf (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SPM_VMID is a global resource, SPM access the video memory according to
SPM_VMID. The initial valude of SPM_VMID is 0 which is used by kernel.
That means UMD can overwrite the memory of VMID0 by enabling SPM, that
is really dangerous.

Initialize SPM_VMID with 0xf, it messes up other user mode process at
most.

v2: squash in indentation fix

Subject: drm/amdgpu: no need to clean debugfs at amdgpu

drm_minor_unregister will invoke drm_debugfs_cleanup
to clean all the child node under primary minor node.
We don't need to invoke amdgpu_debugfs_fini and
amdgpu_debugfs_regs_cleanup to clean agian.
Otherwise, it will raise the NULL pointer like below.

Subject: drm/amdgpu: release drm_device after amdgpu_driver_unload_kms
MIME-Version: 1.0

If we release drm_device before amdgpu_driver_unload_kms,
then it will raise the error below. Therefore, we need to
place it before amdgpu_driver_unload_kms.

Subject: drm/amdgpu/powerplay: nv1x, renior copy dcn clock settings of
 watermark to smu during boot up

dc to pplib interface is changed for navi1x, renoir.
display_config_changed is not called by dc anymore.
smu_write_watermarks_table is not executed for navi1x, renoir
during boot up.

solution: call smu_write_watermarks_table just after dc pass
watermark clock settings to pplib

Subject: drm/amdgpu/powerplay: Refactor SMU message handling for safety

Move the responsibility for reading argument registers into the
smu_send_smc_msg* implementations, so that adding a message-sending lock
to protect the SMU registers will result in the lock still being held
when the argument is read.

v2: transition smu_v12_0, it's asics, and vega20

Subject: drm/amdgpu/powerplay: Remove deprecated smc_read_arg

The new interface reads the argument in the call to send the message, so
this is no longer needed, and shouldn't be used for concurrency safety
reasons.

Subject: drm/amdgpu/smu: Add message sending lock

This adds a message lock to the smu_send_smc_msg* implementations to
protect against concurrent access to the mmu registers used to
communicate with the SMU

v2: Implement for smu_v12_0 as well

v3: Add mutex_init for message_lock

Preliminary stub to add engines underneath /sys/class/drm/cardN/, so
that we can expose properties on each engine to the sysadmin.

To start with we have basic analogues of the i915_query ioctl so that we
can pretty print engine discovery from the shell, and flesh out the
directory structure. Later we will add writeable sysadmin properties such
as per-engine timeout controls.

An example tree of the engine properties on Braswell:
    /sys/class/drm/card0
    └── engine
        ├── bcs0
        │   ├── capabilities
        │   ├── class
        │   ├── instance
        │   ├── known_capabilities
        │   └── name
        ├── rcs0
        │   ├── capabilities
        │   ├── class
        │   ├── instance
        │   ├── known_capabilities
        │   └── name
        ├── vcs0
        │   ├── capabilities
        │   ├── class

            ├── class
            ├── instance
            ├── known_capabilities
            └── name

v2: Include stringified capabilities
v3: Include all known capabilities for futureproofing.
v4: Combine the two caps loops into one

v5: Hide underneath Kconfig.unstable for wider discussion

Subject: drm/i915/gt: Expose engine->mmio_base via sysfs

Use the per-engine sysfs directory to let userspace discover the
mmio_base of each engine. Prior to recent generations, the user
accessible registers on each engine are at a fixed offset relative to
each engine -- but require absolute addressing. As the absolute address
depends on the actual physical engine, this is not always possible to
determine from userspace (for example icl may expose vcs1 or vcs2 as the
second vcs engine). Make this easy for userspace to discover by
providing the mmio_base in sysfs.

Subject: drm/i915/gt: Expose timeslice duration to sysfs

Execlists uses a scheduling quantum (a timeslice) to alternate execution
between ready-to-run contexts of equal priority. This ensures that all
users (though only if they of equal importance) have the opportunity to
run and prevents livelocks where contexts may have implicit ordering due
to userspace semaphores.

The timeslicing mechanism can be compiled out with

	./scripts/config --set-val DRM_I915_TIMESLICE_DURATION 0

The timeslice duration can be adjusted per-engine using,

	/sys/class/drm/card?/engine/*/timeslice_duration_ms

Subject: drm/i915/gt: Expose busywait duration to sysfs

We busywait on an inflight request (one that is currently executing on
HW, and so might complete quickly) prior to setting up an interrupt and
sleeping. The trade off is that we keep an expensive CPU core busy in
order to avoid wake up latency: where that trade off should lie is best
left to the sysadmin.

The busywait mechanism can be compiled out with

	./scripts/config --set-val DRM_I915_SPIN_REQUEST 0

The maximum busywait duration can be adjusted per-engine using,

	/sys/class/drm/card?/engine/*/ms_busywait_duration_ns

Subject: drm/i915/gt: Expose reset stop timeout via sysfs

When we allow ourselves to sleep before a GPU reset after disabling
submission, even for a few milliseconds, gives an innocent context the
opportunity to clear the GPU before the reset occurs. However, how long
to sleep depends on the typical non-preemptible duration (a similar
problem to determining the ideal preempt-reset timeout or even the
heartbeat interval). As this seems of a hard policy decision, punt it to
userspace.

The timeout can be adjusted using

	/sys/class/drm/card?/engine/*/stop_timeout_ms

Subject: drm/i915/gt: Expose preempt reset timeout via sysfs

After initialising a preemption request, we give the current resident a
small amount of time to vacate the GPU. The preemption request is for a
higher priority context and should be immediate to maintain high
quality of service (and avoid priority inversion). However, the
preemption granularity of the GPU can be quite coarse and so we need a
compromise.

The preempt timeout can be adjusted per-engine using,

	/sys/class/drm/card?/engine/*/preempt_timeout_ms

and can be disabled by setting it to 0.

Subject: drm/i915/gt: Expose heartbeat interval via sysfs

We monitor the health of the system via periodic heartbeat pulses. The
pulses also provide the opportunity to perform garbage collection.
However, we interpret an incomplete pulse (a missed heartbeat) as an
indication that the system is no longer responsive, i.e. hung, and
perform an engine or full GPU reset. Given that the preemption
granularity can be very coarse on a system, we let the sysadmin override
our legacy timeouts which were "optimised" for desktop applications.

The heartbeat interval can be adjusted per-engine using,

	/sys/class/drm/card?/engine/*/heartbeat_interval_ms

Subject: drm/panel: Add DT bindings for Novatek NT35510-based panels

This adds device tree bindings for the Novatek NT35510-based
family of panels. Since several such panels are in existence
we define bindings common for all, and define the compatible
string for one certain panel (Hydis HVA40WV1).

As other panels are discovered and investigated, we can add
more compatibles to the binding using oneOf constructions.

Subject: drm/panel: Add driver for Novatek NT35510-based panels

This adds a driver for panels based on the Novatek NT35510
display driver IC, such as the Hydis HVA40WV1 panel found
in the Samsung GT-S7710.

The NT35510 can be used with both internal and external
backlight (such as GPIO backlight) so we support both:
if no external backlight is found, we register a subdriver
for the internal backlight.

+ * The actual panels using this component have different names, but

+ * This driver is for the DSI interface to panels using the NT35510.

Subject: dt-bindings: display: add panel-timing.yaml

Add meta-schema variant of panel-timing and
reference it from panel-common.yaml.

Part of this came form other files with other
licenses - original commits:

commit cc3f414cf2e4 ("video: add of helper for display timings/videomode")
commit 86f46565dff3 ("dt-bindings: display: display-timing: Add property to configure sync drive edge")
commit 9cad9c95d7e8 ("Documentation: DocBook DRM framework documentation")

The original authors acked the license change to:
(GPL-2.0-only OR BSD-2-Clause)

v2:
  - Got OK from original authors for re-license
    Huge thanks for the quick replies!
  - Typo fixes (Oleksandr)
  - Drop -array variant when not needed (Maxime)
  - Replace oneOf:... with enum (Maxime)
  - Drop type from clock-frequency (Rob)
  - Drop "|" when not needed (Rob)

v3:
  - Added comment to acks that are only for the license change
  - Add yaml document terminator "..."
  - Updated description (removed reference to native-mode)

From 4dd23a47d693c7f8d182fd8cc18081ff612c5271 Mon Sep 17 00:00:00 2001
From: Sam Ravnborg <sam@ravnborg.org>
Date: Sun, 16 Feb 2020 19:15:10 +0100
Subject: dt-bindings: display: convert display-timings to DT schema

Add display-timings.yaml - that references panel-timings.yaml.
display-timings.yaml will be used for display bindings
when they are converted to meta-schema format.

For now the old display-timing.txt points to the new
display-timings.yaml - and all users are left as-is.

v2:
  - Updated native-mode description

v3:
  - Simpler "^timing" pattern (Rob)
  - timing node is of type object (Rob)
  - added display-timings to panel-common.yaml
  - added yaml document terminator "..."

-required properties:
- - none
-
-optional properties:
- - native-mode: The native mode for the display, in case multiple modes are
-		provided. When omitted, assume the first node is the native.
-
-timing subnode
---------------
-
-required properties:
- - hactive, vactive: display resolution
- - hfront-porch, hback-porch, hsync-len: horizontal display timing parameters
-   in pixels
-   vfront-porch, vback-porch, vsync-len: vertical display timing parameters in

-Note: In addition to being used as subnode(s) of display-timings, the timing
-      subnode may also be used on its own. This is appropriate if only one mode
-      need be conveyed. In this case, the node should be named 'panel-timing'.
-
-
-Example:
-
-	display-timings {
-		native-mode = <&timing0>;
-		timing0: 1080p24 {
-			/* 1920x1080p24 */
-			clock-frequency = <52000000>;
-			hactive = <1920>;
-			vactive = <1080>;
-			hfront-porch = <25>;
-			hback-porch = <25>;
-			hsync-len = <25>;
-			vback-porch = <2>;
-			vfront-porch = <2>;
-			vsync-len = <2>;
-			hsync-active = <1>;
-		};
-	};
-
-Every required property also supports the use of ranges, so the commonly used
-datasheet description with minimum, typical and maximum values can be used.
-
-Example:
-
-	timing1: timing {
-		/* 1920x1080p24 */
-		clock-frequency = <148500000>;
-		hactive = <1920>;
-		vactive = <1080>;
-		hsync-len = <0 44 60>;
-		hfront-porch = <80 88 95>;
-		hback-porch = <100 148 160>;
-		vfront-porch = <0 4 6>;
-		vback-porch = <0 36 50>;
-		vsync-len = <0 5 6>;
-	};

Subject: dt-bindings: display: convert panel-dpi to DT schema

With panel-timing converted, now convert the single
remaining .txt user in panel/ of panel-timing to DT schema.

v2:
  - Drop Thierry as maintainer, as this is not a general panel binding
    and I have no acks.
  - Drop requirement for a panel- specific binding - "panel-dpi" is enough
  - Updated example

v3:
  - added yaml document terminator "..."
  - always require a specific binding - panel-dpi (based on feedback from Rob)
  - use "power-supply" for the supply property, and made it mandatory
    "power-supply" is the standard property for panels

Subject: drm/panel: simple: add panel-dpi support

The panel-dpi compatible is a fallback that
allows the DT to specify the timing.

When matching panel-dpi expect the device tree to include the
timing information for the display-panel.

Background for this change:
There are a lot of panels and new models hits the market very often.
It is a lost cause trying to chase them all and users of new panels
will often find them in situations that the panel they ues are not
supported by the kernel.
On top of this a lot of panels are customized based on customer
specifications.

Including the panel timing in the device tree allows for a simple
way to describe the actual HW and use this description in a generic
way in the kernel.
This allows uses of proprietary panels, or panels which are not
included in the kernel, to specify the timing in the device tree
together with all the other HW descriptions.
And thus, using the device tree it is then easy to add support
for an otherwise unknown panel.

The current support expect panels that do not require any
delays for prepare/enable/disable/unprepare.

Oleksandr Suvorov replied:
I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using
panel settings from the following patch:
https://lore.kernel.org/linux-arm-kernel/20200115123401.2264293-4-oleksandr.suvorov@toradex.com/

It works for me, thanks!

Subject: drm/simple-kms: Add drm_simple_encoder_{init,create}()

This patch makes the internal encoder implementation of the simple
KMS helpers available to drivers.

These simple-encoder helpers initialize an encoder with an empty
implementation. This covers the requirements of most of the existing
DRM drivers. A call to drm_simple_encoder_create() allocates and
initializes an encoder instance, a call to drm_simple_encoder_init()
initializes a pre-allocated instance.

v3:
	* remove drm_simple_encoder_create(); not required yet
	* provide more precise documentation
v2:
	* move simple encoder to KMS helpers
	* remove name argument; simplifies implementation
	* don't allocate with devm_ interfaces; unsafe with DRM

Subject: drm/qxl: Use simple encoder

The qxl driver uses an empty implementation for its encoder. Replace
the code with the generic simple encoder.

v4:
	* handle errors returned from drm_simple_encoder_init()
v2:
	* rebase onto new simple-encoder interface

Subject: drm/i915/crc: move pipe_crc from drm_i915_private to intel_crtc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Having an array pipe_crc[I915_MAX_PIPES] in struct drm_i915_private
should be an obvious clue this should be located in struct intel_crtc
instead. Make it so.

As a side-effect, fix some errors in indexing pipe_crc with both pipe
and crtc index. And, of course, reduce the size of i915_drv.h.

Unused since commit f97108d1d0fa ("drm/i915: add dynamic performance
control support for Ironlake"). That's a little over ten years. Good
riddance.

Subject: drm/i915/dsi: Remove readback of panel orientation on BYT / CHT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 82daca297506 ("drm/i915: Add "panel orientation" property to the
panel connector, v6.") uses hardware state readback to determine if the
GOP is rotating the image by 180 degrees to compensate for upside-down
mounted panels.

When I wrote that commit I tried to find the VBT bits the GOP used to
decide to rotate the image, but I could not find them. Back then I only
looked at the rotation bits in struct mipi_config and these read 0 on
the 1 BYT device I have with an upside-down mounted panel
(a GP-electronic T701 tablet). While working on a similar problem on a
BYT device with an eDP panel I noticed that the new
intel_dsi_get_panel_orientation() helper which gets used on newer
SoCs (Apollo-Lake, etc.) checks the rotate_180 bit in the
BDB_GENERAL_FEATURES VBT block.

I've checked and this bit indeed is set on the GP-electronic T701 tablet,
so using the generic intel_dsi_get_panel_orientation() helper there does
the right thing without needing any extra readback of hw state.

This commit removes the special handling of the panel orientation for
DSI panels on BYT/CHT devices, bringing the handling in line with the
handling of DSI panels on other devices.

 panel-orientation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some devices with a builtin panel have the panel mounted upside down,
this is indicated by the rotate_180 bit in the BDB_GENERAL_FEATURES VBT
block.

We store this info in dev_priv->vbt.orientation, use this to set the
connector's orientation property so that fbcon and userspace will show
the image the right way up on devices with an upside-down mounted panel.

This fixes the image being upside-down on a Teclast X89 tablet.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Supposedly both src coordinates have to even when doing 90/270
degree rotation with RGB565. This is definitely true for the
X coordinate (we just get a black screen when it is odd). My
experiments didn't show any misbehaviour with an odd
Y coordinate, but let's trust the spec and reject that one
as well.

v2: Ignore ccs hsub/vsub
v3: Clarify the CCS special (Maarten)
    Deal with tgl+ CCS modifiers where we
    do need to look at hsub/vsub

Subject: drm/i915: Add missing commas to dbuf tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The preferred style is to sprinkle commas after each array and
structure initialization, whether or not it happens to be the
last element/member (only exception being sentinel entries which
never have anything after them). This leads to much prettier
diffs if/when new elements/members get added to the end of the
initialization. We're not bound by some ancient silly mandate
to omit the final comma.

Subject: drm/i915: Use a sentinel to terminate the dbuf slice arrays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make life a bit simpler by sticking a sentinel at the end of
the dbuf slice arrays. This way we don't need to pass in the
size. Also unify the types (u8 vs. u32) for active_pipes.

Subject: video: fbdev: w100fb: fix sparse warnings

* Add missing __iomem annotations where needed.
* Make w100fb_probe() static.
* Return NULL pointer (instead of using plain integer) in
  w100_get_xtal_tabl().

Subject: video: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: drm/i915: Use intel_plane_data_rate for min_cdclk calculation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There seems to be a bit of confusing redundancy in a way, how
plane data rate/min cdclk are calculated.
In fact both min cdclk, pixel rate and plane data rate are all
part of the same formula as per BSpec.

However currently we have intel_plane_data_rate, which is used
to calculate plane data rate and which is also used in bandwidth
calculations. However for calculating min_cdclk we have another
piece of code, doing almost same calculation, but a bit differently
and in a different place. However as both are actually part of same
formula, probably would be wise to use plane data rate calculations
as a basis anyway, thus avoiding code duplication and possible bugs
related to this.

Another thing is that I've noticed that during min_cdclk calculations
we account for plane scaling, while for plane data rate, we don't.
crtc->pixel_rate seems to account only for pipe ratio, however it is
clearly stated in BSpec that plane data rate also need to account
plane ratio as well.

So what this commit does is:
- Adds a plane ratio calculation to intel_plane_data_rate
- Removes redundant calculations from skl_plane_min_cdclk which is
  used for gen9+ and now uses intel_plane_data_rate as a basis from
  there as well.

v2: - Don't use 64 division if not needed(Ville Syrjälä)
    - Now use intel_plane_pixel_rate as a basis for calculations both
      at intel_plane_data_rate and skl_plane_min_cdclk(Ville Syrjälä)

v3: - Again fix the division macro
    - Fix plane_pixel_rate to pixel_rate at intel_plane_pixel_rate
      callsites

v4: - Renamed skl_plane_ratio function back(Ville Syrjälä)

v5: - Don't precalculate plane pixel rate for invisible plane,
      check for visibility first, as in invisible case it will
      have dst_w and dst_h equal to zero, causing divide error.

v6: - Removed useless warn in intel_plane_pixel_rate(Ville Syrjälä)
    - Fixed alignment in intel_plane_data_rate(Ville Syrjälä)
    - Changed pixel_rate type to be unsigned int in
      skl_plane_min_cdclk(Ville Syrjälä)

From 353ad959a0bc6d702218f9d77ff47bf80e3c2075 Mon Sep 17 00:00:00 2001
From: Imre Deak <imre.deak@intel.com>

Subject: drm/i915: Keep the global DPLL state in a DPLL specific struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For clarity add a new DPLL specific struct to the i915 device struct and
move all DPLL fields into it. Accordingly remove the dpll_ prefixes, as
the new struct already provides the required namespacing.

Subject: drm/i915: Move DPLL frequency calculation to intel_dpll_mgr.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move all the DPLL params->DPLL frequency conversion functions to
intel_dpll_mgr.c where the corresponding inverse conversions are.

The GEN11+ TBT PLL outputs multiple frequencies and for selecting the
one in use we need to check the DDI CLK mux. As part of the DDI clock
logic this selection is kept in intel_ddi.c.

 it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For clarity keep the SKL DPLL ref clock in a variable instead of
open-coding it. Store the value in kHZ units as done on other platforms.
This allows us in a later patch to keep track of the DPLL ref clock in a
more unified way across all platforms.

The types of PLLs used for HDMI/DP on HSW are WRPLL/LCPLL accordingly,
so use these names to align better with the rest of WRPLL/LCPLL function
names elsewhere.

Instead of reading out the WRPLL/SPLL control values from HW, we can use
the DPLL state that was already read out, or swapped-to.

Subject: drm/i915: Unify the DPLL ref clock frequency tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All platforms using the shared DPLL framework use 3 reference clocks for
their DPLLs: SSC, non-SSC and DSI. For a more unified way across
platforms store the frequency of these ref clocks as part of the DPLL
global state. This also allows us to keep the HW access reading out the
ref clock value separate from the DPLL frequency calculation that
depends on the ref clock.

For now add only the SSC and non-SSC ref clocks, as the pre-ICL DSI code
has its own logic for calculating DPLL parameters instead of the shared
DPLL framework.

v2:
- Apply the ICL combo PHY PLL ref_clock/2 adjustment during the
  frequency->PLL param conversion direction as well. (CI shards)
- s/kHZ/kHz/ (Ville)

Subject: drm/etnaviv: Ignore MC when checking runtime suspend idleness
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without that runtime suspend is often blocked due to
etnaviv_gpu_rpm_suspend() returning -EBUSY since the FE seems to trigger
the MC in its idle loop.

Ignoring the MC bit makes the GPU suspend as expected. This was tested
on GC7000.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the GPU isn't idle after signalling pm_runtime_mark_last_busy() plus
waiting for the autosuspend delay there's likely something wrong with
the way we check idleness so warn about that.

Subject: drm/i915/hdcp: conversion to struct drm_device based logging macros.

Converts remaining instances of the printk based logging macros in
i915/display/intel_hdcp.c with the struct drm_device based macros
manually.

This is continuation of commit 65833c463886 ("drm/i915/hdcp: conversion
to struct drm_device based logging macros.")

v2:
  i915_dev_priv is used instead of drm_device for reusability [JaniN]
v3:
  Made it independent from the series.
  once instance of dev_priv naming is changed to i915 [Jani N]

Subject: drm/i915: Fix kbuild test robot build error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

has_transcoder() was unused because function which was using it,
intel_display_capture_error_state() defined under
CONFIG_DRM_I915_CAPTURE_ERROR.
Moving has_transcoder() to under CONFIG_DRM_I915_CAPTURE_ERROR.
No functional change.

Fixes: d54c1a513c48 ("drm/i915: Fix broken transcoder err state")

Subject: drm/i915/vgpu: improve vgpu abstractions

Add intel_vgpu_register() abstraction, rename i915_detect_vgpu() to
intel_vgpu_detect() to match other function naming, un-inline
intel_vgpu_active(), intel_vgpu_has_full_ppgtt() and
intel_vgpu_has_huge_gtt() to reduce header interdependencies.

The i915_vgpu.[ch] filename and intel_vgpu_ prefix discrepancy remains.

It irks me to use crtc_state_is_legacy_gamma() inside the guts
of the CHV color management code. Let's get rid of it and instead
just consult cgm_mode to figure out if we want to enable the pipe
gamma or the CGM gamma.

Also CHV display engine is based on i965/g4x so we should fall back
to the i965 path when the CGM gamma is not used.

Subject: drm/i915/gem: Consolidate ctx->engines[] release

Use the same engine_idle_release() routine for cleaning all old
ctx->engine[] state, closing any potential races with concurrent execbuf
submission.

v2ish: Use the ce->pin_count to close the execbuf gap.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1241

Subject: drm/i915/gem: Check that the context wasn't closed during setup

As setup takes a long time, the user may close the context during the
construction of the execbuf. In order to make sure we correctly track
all outstanding work with non-persistent contexts, we need to serialise
the submission with the context closure and mop up any leaks.

Subject: drm/i915: Drop vma is-closed assertion on insert

The is-closed flag may be added after we have acquired the vma under the
ctx->mutex, but will not take effect until after we release the
vm->mutex. i.e. the flag may be set on the vma as attempt to bind it and
that will cause the vma to be unbound later after we unpin it.

Subject: drm/i915/gt: Drop the timeline->mutex as we wait for retirement

As we have pinned the timeline (using tl->active_count), we can safely
drop the tl->mutex as we wait for what we believe to be the final
request on that timeline. This is useful for ensuring that we do not
block the engine heartbeat by hogging the kernel_context's timeline on a
dead GPU.

Subject: drm/i915: Drop inspection of execbuf flags during evict

With the goal of removing the serialisation from around execbuf, we will
no longer have the privilege of there being a single execbuf in flight
at any time and so will only be able to inspect the user's flags within
the carefully controlled execbuf context. i915_gem_evict_for_node() is
the only user outside of execbuf that currently peeks at the flag to
convert an overlapping softpinned request from ENOSPC to EINVAL. Retract
this nicety and only report ENOSPC if the location is in current use,
either due to this execbuf or another.

Subject: drm/i915/gem: Extract transient execbuf flags from i915_vma

For our convenience, and to avoid frequent allocations, we placed some
lists we use for execbuf inside the common i915_vma struct. As we look
to parallelise execbuf, such fields guarded by the struct_mutex BKL must
be pulled under local control. Instead of using the i915_vma as our
primary means of tracking the user's list of objects and their virtual
mappings, we use a local eb_vma with the same lists as before (just now
local not global).

This should allow us to only perform the lookup of vma used for
execution once during the execbuf ioctl, as currently we need to remove
our secrets from inside i915_vma everytime we drop the struct_mutex as
another execbuf may use the shared locations.

Once potential user visible consequence is that we can remove the
requirement that the execobj[] be unique, and only require that they do

From: Chris Wilson <chris@chris-wilson.co.uk>
Date: Tue, 3 Mar 2020 20:43:45 +0000
Subject: drm/i915/gem: Only call eb_lookup_vma once during execbuf ioctl

As we no longer stash anything inside i915_vma under the exclusive
protection of struct_mutex, we do not need to revoke the i915_vma
stashes before dropping struct_mutex to handle pagefaults. Knowing that
we must drop the struct_mutex while keeping the eb->vma around, means
that we are required to hold onto to the object reference until we have
marked the vma as active.

Subject: drm/hdcp: optimizing the srm handling

As we are not using the sysfs infrastructure anymore, link to it is
removed. And global srm data and mutex to protect it are removed,
with required handling at revocation check function.

v2:
  srm_data is dropped and few more comments are addressed.
v3:
  ptr passing around is fixed with functional testing.
v4:
  fix htmldoc [lkp]

Subject: drm/i915/hdcp: Mandate (seq_num_V==0) at first RecvId msg

HDCP Repeater initializes seq_num_V to 0 at the beginning of
hdcp Session i.e. after AKE_init received, refer
HDCP 2.2 Spec HDMI PAGE 19, DP PAGE 20.

HDCP 2.2 Comp specs 1B-06 test verifies that whether DUT
considers failure of authentication if the repeater provides a
non-zero value in seq_num_V in the first,
RepeaterAuth_Send_ReceiverID_List message.

Make sure that HDCP repeater initializes seq_num_V to zero at
beginning of session i.e. after AKE_Init, fail the Auth if
there is non zero seq_num_V.

v2:
- Used existing hdcp2_encrypted flag instead of
  declaring new flag. [Ram]

Subject: drm/dp: Introduce EDID-based quirks

The whole point of using OUIs is so that we can recognize certain
devices and potentially apply quirks for them. Normally this should work
quite well, but there appears to be quite a number of laptop panels out
there that will fill the OUI but not the device ID. As such, for devices
like this I can't imagine it's a very good idea to try relying on OUIs
for applying quirks. As well, some laptop vendors have confirmed to us
that their panels have this exact issue.

So, let's introduce the ability to apply DP quirks based on EDID
identification. We reuse the same quirk bits for OUI-based quirks, so
that callers can simply check all possible quirks using
drm_dp_has_quirk().

Subject: drm/i915: Force DPCD backlight mode on X1 Extreme 2nd Gen 4K AMOLED
 panel

The X1 Extreme is one of the systems that lies about which backlight
interface that it uses in its VBIOS as PWM backlight controls don't work
at all on this machine. It's possible that this panel could be one of
the infamous ones that can switch between PWM mode and DPCD backlight
control mode, but we haven't gotten any more details on this from Lenovo
just yet. For the time being though, making sure the backlight 'just
works' is a bit more important.

So, add a quirk to force DPCD backlight controls on for these systems
based on EDID (since this panel doesn't appear to fill in the device ID).
Hopefully in the future we'll figure out a better way of probing this.

Changes since v2:
* The bugzilla URL is deprecated, bug reporting happens on gitlab now.
  Update the messages we print to reflect this
* Also, take the opportunity to move FDO_BUG_URL out of i915_utils.c and
  into i915_utils.h so that other places which print things that aren't
  traditional errors but are worth filing bugs about, can actually use
  it.

Subject: drm/i915: Force DPCD backlight mode for some Dell CML 2020 panels

According to Dell, trying to match their panels via OUI is not reliable
enough and we've been told that we should check against the EDID
instead. As well, Dell seems to have some panels that are actually
intended to switch between using PWM for backlight controls and DPCD for
backlight controls depending on whether or not the panel is in HDR or
SDR mode. Yikes.

Regardless, we need to add quirks for these so that DPCD backlight
controls get enabled by default, since without additional driver support
that's the only form of brightness control that will work. Hopefully in
the future we can remove these quirks once we have a better way of
probing for this.

Changes since v1:
* Add one more EDID per Dell's request
* Remove model number (which is possibly wrong) and replace with Dell
  CML 2020 systems

Subject: drm/i915/ehl: Check PHY type before reading DPLL frequency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

intel_ddi_clock_get() tests the DPLL ID against DPLL_ID_ICL_TBTPLL (2)
to determine whether to try to descend into a TBT-specific handler.
However this test will also be true when DPLL4 on EHL is used since that
shares the same DPLL ID (2).

Add an extra check to ensure the PHY is actually a Type-C PHY before
descending into the TBT handling.  This should ensure EHL still takes
the correct code path and somewhat future-proof the code as well.

v2: Drop the gen+ check since only gen11+ platforms can have Type-C
    outputs.  (Imre)

Subject: drm/i915: Apply i915_request_skip() on submission

Trying to use i915_request_skip() prior to i915_request_add() causes us
to try and fill the ring upto request->postfix, which has not yet been
set, and so may cause us to memset() past the end of the ring.

Instead of skipping the request immediately, just flag the error on the
request (only accepting the first fatal error we see) and then clear the
request upon submission.

As we release the head requests back into the queue, propagate any
change in error status that may have occurred while the requests were
temporarily suspended.

Subject: drm/i915: panel: Use intel_panel_compute_brightness() from
 pwm_setup_backlight()

Use intel_panel_compute_brightness() from pwm_setup_backlight() so that
we correctly take i915_modparams.invert_brightness and/or
QUIRK_INVERT_BRIGHTNESS into account when setting + getting the initial
brightness value.

Subject: drm/i915: Add invert-brightness quirk for Thundersoft TST178 tablet

The Thundersoft TST178 tablet uses a DSI panel with an external PWM
controller (as all DSI panels do). But unlike other DSI panels a duty-cycle
of 100% turns the backlight off and 0% sets it to maximum brightness.

I've checked the VBT and there is a BDB_LVDS_BACKLIGHT section, but
it does not set the active_low_pwm flag. This tablet re-uses the main
PCI vendor and product ids for the subsystem ids, so I see no other option
then to add a DMI based quirk to fix this.

Note that the PWM backlight code in intel_panel.c currently does not honor
the vbt.active_low_pwm flag, but that does not matter in this case.

As we started marking the ce->gem_context as NULL on closure, we can no
longer use that to carry closure information. Instead, we can look at
whether the context was killed on closure instead.

Subject: drm/amdgpu: clean wptr on wb when gpu recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TDR will be randomly failed due to compute ring
test failure. If the compute ring wptr & 0x7ff(ring_buf_mask)
is 0x100 then after map mqd the compute ring rptr will be
synced with 0x100. And the ring test packet size is also 0x100.
Then after invocation of amdgpu_ring_commit, the cp will not
really handle the packet on the ring buffer because rptr is equal to wptr.

1)for gfx IB test we shouldn't insert DE meta data

2)we should make sure IB test finished before we
send event 3 to hypervisor otherwise the IDLE from
event 3 will preempt IB test, which is not designed
as a compatible structure for MCBP

Subject: drm/amdgpu: stop using sratch_reg in IB test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

scratch_reg0 is used by RLCG for register access usage
in SRIOV case.

both CP firmware and driver can invoke RLCG to do
certain register access (through scratch_reg0/1/2/3)
but rlcg now dosen't have race concern so if two
clients are in parallel doing the RLCG reg access
then we are colliding,

GFX IB test is a runtime work, so it is forbidden
to use scrach_reg0/1/2/3 during IB test period

note:
Although we can only have this change for SRIOV, but
looks it doesn't worth the effort to differentiate
bare-metal with SRIOV on the GFX ib test

Subject: drm/amd/display: Link training TPS1 workaround add back in dpcd

[Why]
Previously implemented early_cr_pattern we mistook dp_hw_link_settings
for a redundant call of dpcd_set_link_settings

[How]
revert the changes to dpcd_set_link_settings calls for this workaround.
Do not need to revert the entire change since it only affects patched
case

Subject: drm/amd/display: Move mod_hdcp_displays to mod_hdcp struct

[Why]
Reset connection is called before remove display in mod_hdcp. When
remove display is called, the display structure has been zeroed from
reset connection. Since no displays can be found, remove display does
not properly reset the hardware. This causes validation errors when
another display is plugged into a different port afterwards.

[How]
Moved displays structure out of connections structure. Displays
structure is now directly within mod_hdcp. Displays is no longer zeroed
when reset connection is called.

Subject: drm/amd/display: Add driver support for enabling PSR on DMCUB

[Why]
We want to be able to enable PSR on DMCUB, and fallback to
DMCU when necessary.

[How]
Move psr_on_dmub flag from dc_debug_options to dc_config.

Subject: drm/amd/display: only include FEC overhead if both asic and display
 support FEC

[why]
Some asics don't support FEC but FEC overhead is added into link
bandwidth calculation by mistake. This causes certain timing cannot be
validated.

[how]
Only include FEC overhead if both asic and display support FEC.

Subject: drm/amd/display: add worst case dcc meta pitch to fake plane

[why]
When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

[how]
Change get_default_swizzle_mode to something more general so we don't
end up with a separate function for every missing field in the fake
plane. Add a reasonable dcc meta to the fake plane when it is filled in,
so we filter out modes that don't have enough bandwidth. To do this, we
take the screen width and align it to 1024(8k 60)

Subject: drm/amd/display: Make clock table struct more accessible

[WHY & HOW]
In order to correctly intepret clock table, num_states is also needed.
This field did not get moved with clock_table but should next to it for
easier access/viewing.

[how]
Allow vsc info packet if vsc is supported.  Update vsc based on test
pattern request.  Remove dpg_is_blanked polling, apply hardware global
lock instead to ensure double buffered dpg is updated with vsc in one
frame

Subject: drm/amd/display: program DPG_OFFSET_SEGMENT for odm_pipe

[why]
When test pattern is enabled with ODM combine, test pattern is generated
by piecing multiple DPGs image together.  The current code will program
all DPGs with horizontal offset of 0. This will cause all DPGs to output
the beginning of the pattern. Instead each DPG should program a
horizontal offset of its x position to form a continous pattern when
pieced together.

Subject: drm/amd/display: fix image corruption with ODM 2:1 DSC 2 slice

[why]
When combining two or more pipes in DSC mode, there will always be more
than 1 slice per line.  In this case, as per DSC rules, the sink device
is expecting that the ICH is reset at the end of each slice line (i.e.
ICH_RESET_AT_END_OF_LINE must be configured based on the number of
slices at the output of ODM).  It is recommended that software set
ICH_RESET_AT_END_OF_LINE = 0xF for each DSC in the ODM combine.  However
the current code only set ICH_RESET_AT_END_OF_LINE = 0xF when number of
slice per DSC engine is greater than 1 instead of number of slice per
output after ODM combine.

[how]
Add is_odm in dsc config. Set ICH_RESET_AT_END_OF_LINE = 0xF if either
is_odm or number of slice per DSC engine is greater than 1.

Subject: drm/amd/display: Workaround to do HDCP authentication twice on
 certain displays

[Why]
When transitioning from SST to MST, the HDCP repeater in some MST
displays will enter a bad state. The HDCP repeater is recovered after
failing and performing authentication again.

[How]
Add monitor patch to trigger HDCP authentication failure after
encryption is enabled and re-authenticate.

Subject: drm/amd/display: Remove DISPCLK Limit Floor for Certain SMU Versions

[WHY]
SMU FW previously had an issue with lowering display clock to below 100
MHz, and a workaround was put in to limit it.  Newest SMU FW does not
have this issue, and no longer needs the 100MHz cap.

[HOW]
Remove the 100MHz cap based on the SMU FW version.

Subject: drm/amd/display: fix dcc swath size calculations on dcn1

[Why]
Swath sizes are being calculated incorrectly. The horizontal swath size
should be the product of block height, viewport width, and bytes per
element, but the calculation uses viewport height instead of width. The
vertical swath size is similarly incorrectly calculated. The effect of
this is that we report the wrong DCC caps.

[How]
Use viewport width in the horizontal swath size calculation and viewport
height in the vertical swath size calculation.

Subject: drm/amd/display: Set clock optimization required after update clocks

[WHY]
We see an issue that caused clk_optimized_required to be set true in
certain cases, causing passive flips to fail. This is because of a typo
where wm_optimized_required was set twice.

[HOW]
Set clk_optimized_required to false after updating clocks.

Subject: drm/amd/display: Clear link settings on MST disable connector

[Why]
If we have a single MST display and we disconnect it, we dont disable that
link. This causes the old link settings to still exist

Now on a replug for MST we think its a link loss and will try to reallocate
mst payload which will fail, throwing warning below.

[How]
when we disable MST we should clear the cur link settings (lane_count=0 is
good enough). This will cause us to not reallocate payloads earlier than
expected and not throw the warning

Subject: drm/amdgpu/sriov: Use VF-accessible register for gpu_clock_count

Navi12 VK CTS subtest timestamp.calibrated.dev_domain_test failed
because mmRLC_CAPTURE_GPU_CLOCK_COUNT register cannot be
written in VF due to security policy.

Solution: use a VF-accessible timestamp register pair
mmGOLDEN_TSC_COUNT_LOWER/UPPER for SRIOV case.

v2: according to Deucher Alexander's advice, switch to
mmGOLDEN_TSC_COUNT_LOWER/UPPER for both bare metal and SRIOV.

Subject: drm/amdgpu/display: navi1x copy dcn watermark clock settings to smu
 resume from s3 (v2)

 This interface is for dGPU Navi1x. Linux dc-pplib interface depends
 on window driver dc implementation.

 For Navi1x, clock settings of dcn watermarks are fixed. the settings
 should be passed to smu during boot up and resume from s3.
 boot up: dc calculate dcn watermark clock settings within dc_create,
 dcn20_resource_construct, then call pplib functions below to pass
 the settings to smu:
 smu_set_watermarks_for_clock_ranges
 smu_set_watermarks_table
 navi10_set_watermarks_table
 smu_write_watermarks_table

 For Renoir, clock settings of dcn watermark are also fixed values.
 dc has implemented different flow for window driver:
 dc_hardware_init / dc_set_power_state
 dcn10_init_hw
 notify_wm_ranges
 set_wm_ranges

 For Linux
 smu_set_watermarks_for_clock_ranges
 renoir_set_watermarks_table
 smu_write_watermarks_table

 dc_hardware_init -> amdgpu_dm_init
 dc_set_power_state --> dm_resume

 therefore, linux dc-pplib interface of navi10/12/14 is different
 from that of Renoir.

v2: add missing unlock in error case

As long as pipe_ctx is not NULL, the address of members in this struct
cannot be NULL, which means these checks will always evaluate to false.

Subject: drm/vc4: Replace wait_for macros to remove use of msleep

The wait_for macro's for Broadcom VC4 driver used msleep, which is
inappropriate due to its inaccuracy at low values (minimum wait time
is about 30ms on the Raspberry Pi).  This sleep was triggering in
v3d_clean_caches(), causing us to only be able to dispatch ~33 compute
jobs per second.

This patch replaces the macro with the one from the Intel i915 version
which uses usleep_range to provide more accurate waits.

v2: Split from the v3d patch in case this tickles modesetting bugs (by
    anholt)

Subject: drm/etnaviv: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: drm/i915: Don't check uv_wm in skl_plane_wm_equals()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hardware never sees the uv_wm values (apart from
uv_wm.min_ddb_alloc affecting the ddb allocation). Thus there
is no point in comparing uv_wm to determine if we need to
reprogram the watermark registers. So let's check only the
rgb/y watermark in skl_plane_wm_equals(). But let's leave
a comment behind so that the next person reading this doesn't
get as confused as I did when I added this check.

If the ddb allocation ends up changing due to uv_wm
skl_ddb_add_affected_planes() takes care of adding the plane
to the state.

TODO: we should perhaps just eliminate uv_wm from the state
and simply track the min_ddb_alloc for uv instead.

Subject: drm/i915: Don't check for wm changes until we've compute the wms
 fully
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently we're comparing the watermarks between the old and new states
before we've fully computed the new watermarks. In particular
skl_build_pipe_wm() will not account for the amount of ddb space we'll
have. That information is only available during skl_compute_ddb()
which will proceed to zero out any watermark level exceeding the
ddb allocation. If we're short on ddb space this will end up
adding the plane to the state due erronously determining that the
watermarks have changed. Fix the problem by deferring
skl_wm_add_affected_planes() until we have the final watermarks
computed.

Noticed this when trying enable transition watermarks on glk.
We now computed the trans_wm as 28, but we only had 14 blocks
of ddb, and thus skl_compute_ddb() ended up disabling the cursor
trans_wm every time. Thus we ended up adding the cursor to every
commit that didn't actually affect the cursor at all.

MIME-Version: 1.0

Converting error to debug print if sink fails to configure scrambling or
TMDS bit clock ratio. In this case, we are timing out while disabling
the scrambling and setting the SCDC ratio, as there is no response
to the I2C SCDC write from the sink device. Error isn't due to something
wrong done from driver side.

Subject: drm/i915: Return early for await_start on same timeline

Requests within a timeline are ordered by that timeline, so awaiting for
the start of a request within the timeline is a no-op. This used to work
by falling out of the mutex_trylock() as the signaler and waiter had the
same timeline and not returning an error.

changes in v3:
- add missing return value assignment (Francesco)
- re-sort header includes (Sam)
changes in v2:
- rename dsi_generic_write_seq macro to dsi_dcs_write_seq to honor
  the underlying mipi_dsi_dcs_write (Robin)

Subject: drm/i915/gvt: Fix dma-buf display blur issue on CFL

Commit c3b5a8430daad ("drm/i915/gvt: Enable gfx virtualiztion for CFL")
added the support on CFL. The vgpu emulation hotplug support on CFL was
supposed to be included in that patch. Without the vgpu emulation
hotplug support, the dma-buf based display gives us a blur face.

So fix this issue by adding the vgpu emulation hotplug support on CFL.

Fixes: c3b5a8430daad ("drm/i915/gvt: Enable gfx virtualiztion for CFL")

Subject: drm/i915/gvt: cleanup debugfs scan_nonprivbb

Remove extra chatty message for debugfs scan_nonprivbb which is used
to enable scan for non privileged batch on specific engine. Just write
target i915 engine mask instead.

Stop trying to escape out of the gvt layer to find the engine that we
initially setup for use with gvt. Record the engines during initialisation
and use them henceforth.

add/remove: 1/4 grow/shrink: 22/28 up/down: 341/-1410 (-1069)

[Zhenyu: rebase, fix nonpriv register check fault, fix gvt engine
thread run failure.]

From a61ac1e75105a077ec1efd6923ae3c619f862304 Mon Sep 17 00:00:00 2001
From: Chris Wilson <chris@chris-wilson.co.uk>
Date: Fri, 6 Mar 2020 10:08:10 +0800
Subject: drm/i915/gvt: Wean gvt off using dev_priv

Teach gvt to use intel_gt directly as it currently assumes direct HW
access.

[Zhenyu: rebase, fix compiling]

Subject: drm/i915: Add mechanism to submit a context WA on ring submission

This patch adds framework to submit an arbitrary batchbuffer on each
context switch to clear residual state for render engine on Gen7/7.5
devices.

The idea of always emitting the context and vm setup around each request
is primary to make reset recovery easy, and not require rewriting the
ringbuffer. As each request would set up its own context, leaving it to
the HW to notice and elide no-op context switches, we could restart the
ring at any point, and reorder the requests freely.

However, to avoid emitting clear_residuals() between consecutive requests
in the ringbuffer of the same context, we do want to track the current
context in the ring. In doing so, we need to be careful to only record a
context switch when we are sure the next request will be emitted.

This security mitigation change does not trigger any performance
regression. Performance is on par with current mainline/drm-tip.

v2: Update vm_alias params to point to correct address space "vm" due to
changes made in the patch "f21613797bae98773"

From 47f8253d2b8947d79fd3196bf96c1959c0f25f20 Mon Sep 17 00:00:00 2001
From: Prathap Kumar Valsan <prathap.kumar.valsan@intel.com>
Date: Fri, 6 Mar 2020 00:09:57 +0000
Subject: drm/i915/gen7: Clear all EU/L3 residual contexts

On gen7 and gen7.5 devices, there could be leftover data residuals in
EU/L3 from the retiring context. This patch introduces workaround to clear
that residual contexts, by submitting a batch buffer with dedicated HW
context to the GPU with ring allocation for each context switching.

This security mitigation changes does not triggers any performance
regression. Performance is on par with current drm-tips.

v2: Add igt generated header file for CB kernel assembled with Mesa tool
and addressed use of Kernel macro for ptr_align comment.

v3: Resolve Sparse warnings with newly generated, and imported CB
kernel.

v4: Include new igt generated CB kernel for gen7 and gen7.5. Also
add code formatting and compiler warnings changes (Chris Wilson)

Subject: drm/i915/phys: unconditionally call release_memory_region

The release method will undo what we did at creation, and so we
shouldn't care if we have pages or not. Fixes a small leak in the
mock_phys selftest.

The alignment is u64, and yet is_power_of_2() assumes unsigned long,
which might give different results between 32b and 64b kernel.

Subject: drm/gma500/intel_bios.h: Replace zero-length array with
 flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: drm/i915: Always propagate the invocation to i915_schedule

We only call i915_schedule() when we know we have changed the priority
on a request and so require to propagate any change in priority to its
signalers (for PI). By unconditionally checking all of our signalers, we
avoid skipping changes made prior to construction of the request (as the
request may be waited upon before submission when used in parallel).

Subject: drm/i915/gem: Limit struct_mutex to eb_reserve

We only need to serialise the multiple pinning during the eb_reserve
phase. Ideally this would be using the vm->mutex as an outer lock, or
using a composite global mutex (ww_mutex), but at the moment we are
using struct_mutex for the group.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1381

Subject: drm/mm: Break long searches in fragmented address spaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We try hard to select a suitable hole in the drm_mm first time. But if
that is unsuccessful, we then have to look at neighbouring nodes, and
this requires traversing the rbtree. Walking the rbtree can be slow
(much slower than a linear list for deep trees), and if the drm_mm has
been purposefully fragmented our search can be trapped for a long, long
time. For non-preemptible kernels, we need to break up long CPU bound
sections by manually checking for cond_resched(); similarly we should
also bail out if we have been told to terminate. (In an ideal world, we
would break for any signal, but we need to trade off having to perform
the search again after ERESTARTSYS, which again may form a trap of
making no forward progress.)

Since then, ./scripts/get_maintainer.pl --self-test complains:

Subject: drm/i915: properly sanity check batch_start_offset

Check the edge case where batch_start_offset sits exactly on the batch
size.

v2: add new range_overflows variant to capture the special case where
the size is permitted to be zero, like with batch_len.

v3: other way around. the common case is the exclusive one which should
just be >=, with that we then just need to convert the three odd ball
cases that don't apply to use the new inclusive _end version.

Subject: drm: Remove drm_fb_helper add, add all and remove connector calls

drm_fb_helper_{add,remove}_one_connector() and
drm_fb_helper_single_add_all_connectors() are dummy functions now
and serve no purpose. Hence remove their calls.

This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h

This removal is done using below sementic patch and unused variable
compilation warnings are fixed manually.

Subject: drm/fb-helper: Remove drm_fb_helper add, add_all and remove connector
 functions

drm_fb_helper_single_add_all_connectors(),
drm_fb_helper_add_one_connector()
and drm_fb_helper_remove_one_connector() don't keep an array of
connectors anymore and are just dummy. Now we have no callers to these
functions hence remove them.

Subject: drm/i915/selftests: try to rein in alloc_smoke

Depending on RNG we might try to fill an 8G region for every possible
order, using the smallest possible chunk size of 4K, which seems to be
very slow. Try to remedy the situation by adding an overall timeout for
the test, while also selecting each order level in a random fashion.

Date: Tue, 21 Jan 2020 16:43:14 +0100
Subject: dt-bindings: convert rockchip-drm.txt to rockchip-drm.yaml

convert the binding file rockchip-drm.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml

Changes since v2:
- add a missing ">" sign in maintainers list
- change the licens to GPL-2.0-only
- add "additionalProperties: false"
- change the commit message to conform that it was tested on both ARM and ARM64
Changes since v1:
- fixed worng sign-off
- fixed the path of the $id property to be the path of the yaml file

Subject: drm/amdgpu: toggle DF-Cstate when accessing UMC ras error related
 registers

On arcturus, DF-Cstate needs to be toggled off/on
before and after accessing UMC error counter and
error address registers, otherwise, clearing such
registers may fail.

Subject: drm/amdgpu: Fix GPU reset error.

Problem:
During GU reset PSP's sysfs was being wrongly reinitilized
during call to amdgpu_device_ip_late_init which was failing
with duplicate error.
Fix:
Move psp_sysfs_init to psp_sw_init to avoid this. Add guards
in sysfs file's read and write hook agains premature call
if PSP is not finished initialization.

Subject: drm/amdgpu: implement initialization part on VCN2.0 for SRIOV

something need to do for VCN2.0 enablement on SRIOV:
1)use one dec ring and one enc ring
2)allocate MM table for MMSCH usage
3)implement SRIOV version vcn_start which orgnize vcn programing
with patcket format and implement start mmsch for to run those
packet
4)doorbell is changed for SRIOV

Subject: drm/i915/hotplug: Use phy to get the hpd_pin instead of the port (v5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On some platforms such as Elkhart Lake, although we may use DDI D
to drive a connector, we have to use PHY A (Combo Phy PORT A) to
detect the hotplug interrupts as per the spec because there is no
one-to-one mapping between DDIs and PHYs. Therefore, use the
function intel_port_to_phy() which contains the logic for such
mapping(s) to find the correct hpd_pin.

This change should not affect other platforms as there is always
a one-to-one mapping between DDIs and PHYs.

v2:
- Convert the case statements to use PHYs instead of PORTs (Jani)

v3:
- Refactor the function to reduce the number of return statements by
  lumping all the case statements together except PHY_F which needs
  special handling (Jose)

v4:
- Add a comment describing how the HPD pin value associated with any
  port can be retrieved using port or phy enum value. (Jani)

v5:
- Use case ranges instead of individual labels and also normalize the
  return statement by adding -PHY_A to the expression (Ville)

Subject: drm/i915/selftests: Apply a heavy handed flush to i915_active

Due to the ordering of cmpxchg()/dma_fence_signal() inside node_retire(),
we must also use the xchg() as our primary memory barrier to flush the
outstanding callbacks after expected completion of the i915_active.

Subject: drm/i915/execlists: Enable timeslice on partial virtual engine
 dequeue

If we stop filling the ELSP due to an incompatible virtual engine
request, check if we should enable the timeslice on behalf of the queue.

This fixes the case where we are inspecting the last->next element when
we know that the last element is the last request in the execution queue,
and so decided we did not need to enable timeslicing despite the intent
to do so!

Subject: drm/vboxvideo/vboxvideo.h: Replace zero-length array with
 flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: drm/i915/gt: Wait for the wa batch to be pinned

Be sure to wait for the vma to be in place before we tell the GPU to
execute from the wa batch. Since initialisation is mostly synchronous
(or rather at some point during start up we will need to sync anyway),
we can affort to do an explicit i915_vma_sync() during wa batch
construction rather than check for a required await on every context
switch. (We don't expect to change the wa bb at run time so paying the
cost once up front seems preferrable.)

This reverts commit 0f9cdd743f7f8d470fff51b11250f02fc554cf1b.

The interface of the panel is LVDS, not parallel.
The color depth is RGB888, not RGB565.
The panel has additional features, making it not so simple.
The only user (upstream) of this panel is appropriately using panel-lvds.

the important bit is moving the #ifdef earlier before drm_pci_agp_init.

Subject: drm/virtio: factor out the sg_table from virtio_gpu_object

A resource will be a shmem based resource or a (planned)
vram based resource, so it makes sense to factor out common fields
(resource handle, dumb).

v2: move mapped field to shmem object

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The UNSLICE_UNIT_LEVEL_CLKGATE and UNSLICE_UNIT_LEVEL_CLKGATE2 registers
that we update in a few engine workarounds are not masked registers
(i.e., we don't have to write a mask bit in the top 16 bits when
updating one of the lower 16 bits).  As such, these workarounds should
be applied via wa_write_or() rather than wa_masked_en()

Subject: drm/amd/display: update soc bb for nv14

[why]
nv14 previously inherited soc bb from generic dcn 2, did not match
watermark values according to memory team

[how]
add nv14 specific soc bb: copy nv2 generic that it was
using from before, but changed num channels to 8

Subject: drm/amd/display: determine is mst hdcp based on stream instead of
 sink signal

[why]
It is possible even if sink signal is MST but driver enables SST stream.
We should not determine if we should do MST authentication based on
sink's capability.
Instead we should determine whether to do MST authentication based on
what we have enabled in stream.

Subject: drm/amd/display: Not check wm and clk change flag in optimized
 bandwidth.

[Why]
System isn't able to enter S0i3 due to not send display count 0 to smu.
When dpms off, clk changed flag is cleared alreay, and it is checked
when doing optimized bandwidth, and update clocks is bypassed due to the
flag is unset.

[How]
Remove check flag incide the function since watermark values and clocks
values are checked during update to determine whether to perform it, no
need to check it again outside the function.

Subject: drm/amd/display: Program DSC during timing programming

[why]
Link or DIG BE can't be exposed to a higher stream bandwidth than they
can handle. When DSC is required to fit the stream into the link
bandwidth, DSC has to be programmed during timing programming to ensure
this. Without it, intermittent issues such as black screen after S3 or a
hot-plug can be seen.

[how]
Move DSC programming from enabling stream on link to timing setup.

Subject: drm/amd/display: determine rx id list bytes to read based on device
 count

[why]
Some RX doesn't like us to read rx id list upto max rx id list size.  As
discussed, we decided to read rx id list based on device count.

[how]
According to HDCP specs the actual size of rx id list is calculated as
rx id list size = 2+3+16+5*device_count.  We will read 16 bytes at a
time until it reached or exceeded rx id list size.

Subject: drm/amd/display: fix a minor HDCP logging error

[why]
In HDCP Uninitialzed State, a CPIRQ event would cause log output
internal policy error because the CPIRQ event is not recognized as
unexpected event.

[how]
CPIRQ is issued in HDCP uninitialized state is unexpected.  We should
set unexpected event flag in event ctx.

Subject: drm/amd/display: Stop if retimer is not available

Raven provides retimer feature support that requires i2c interaction in
order to make it work well, all settings required for this configuration
are loaded from the Atom bios which include the i2c address. If the
retimer feature is not available, we should abort the attempt to set
this feature, otherwise, it makes the following line return
I2C_CHANNEL_OPERATION_NO_RESPONSE:

 i2c_success = i2c_write(pipe_ctx, slave_address, buffer, sizeof(buffer));
 ...
 if (!i2c_success)
   ASSERT(i2c_success);

This ends up causing problems with hotplugging HDMI displays on Raven,
and causes retimer settings to warn like so:

This commit reworks the way that we handle i2c write for retimer in the
way that we abort this configuration if the feature is not available in
the device. For debug sake, we kept a simple log message in case the
retimer is not available.

Subject: drm/amd/display: writing stereo polarity register if swapped

[why]
on some displays that prefer swapped polarity we were seeing L/R images
swapped because OTG_STEREO_SYNC_OUTPUT_POLARITY would always be mapped
to 0

[how]
fix initial dal3 implementation to properly update the polarity field
according to the crtc_stereo_flags (same as
OTG_STEREO_EYE_FLAG_POLARITY)

Subject: drm/amd/display: separate FEC capability from fec debug flag

[why]
FEC capability query should not be affected by debugging decision on
whether to disable FEC. We should not determine if display supports FEC
by checking debug option.

Subject: drm/amdgpu/display: Fix Pollock Variant Detection

Problem Description:
Currently we are checking internal fused rev id with pci rev id. However, fused
internal rev id is the same on all raven2 parts (in which Dali and Pollock were
based on too), thus Pollock detection fails

Fix:
use the pci rev to preform the detection for bandwidth calculations.

Subject: drm/amdgpu: set compute queue priority at mqd_init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We were changing compute ring priority while rings were being used
before every job submission which is not recommended. This patch
sets compute queue priority at mqd initialization for gfx8, gfx9 and
gfx10.

Policy: make queue 0 of each pipe as high priority compute queue

High/normal priority compute sched lists are generated from set of high/normal
priority compute queues. At context creation, entity of compute queue
get a sched list from high or normal priority depending on ctx->priority

Subject: drm/scheduler: implement a function to modify sched list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement drm_sched_entity_modify_sched() which modifies existing
sched_list with a different one. This is going to be helpful when
userspace changes priority of a ctx/entity then the driver can switch
to the corresponding HW scheduler list for that priority.

Subject: drm/i915: Mark up unlocked update of i915_request.hwsp_seqno

During i915_request_retire() we decouple the i915_request.hwsp_seqno
from the intel_timeline so that it may be freed before the request is
released. However, we need to warn the compiler that the pointer may
update under its nose.

Subject: drm/i915: Polish CHV CGM CSC loading
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Only load the CGM CSC based on the cgm_mode bit like we
do with the gamma/degamma LUTs. And make the function
naming and arguments consistent as well.

TODO: the code to convert the coefficients look totally
bogus. IIRC CHV uses two's complement format but the code
certainly doesn't generate that, so probably negative
coefficients are totally busted.

Split i9xx_load_luts_internal() into neat gmch vs. ilk+ chunks.
Avoids at least one branch in the inner loop, and makes life
a bit less confusing.

To mirror the load_luts path let's clone an ilk+ version
from i9xx_read_lut_8(). I guess the extra branch isn't a huge
issue but feels better to make a clean split.

Content-Transfer-Encoding: 8bit

We're talking about LUT contents here so let's call the thing
'lut' rather than 'blob_data'. This is the name the load_lut()
code used before already.

chv_read_cgm_lut() specifically reads the CGM _gamma_ LUT so
let's rename it to reflect that fact. This also mirrors
the other direction's chv_load_cgm_gamma().

Subject: drm/i915: Clean up integer types in color code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A variable called 'i' having an unsigned type is just looking for
trouble, and using a sized type generally makes no sense either.
Change all of them to just plain old int. And do the same for some
'lut_size' variables which generally provide the loop end codition
for 'i'.

Extract all the 'hw value -> LUT entry' stuff into small helpers
to make the main 'read out the entire LUT' loop less bogged down
by such mundane details.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PIPEGCMAX is a 11.6 (or 1.16 if you will) value. Ie. it can
represent a value of 1.0 when the maximum we can store in the
software LUT is 0.ffff. Clamp the value so that it gets
saturated to the max the uapi supports.

Subject: drm/i915: Pass the crtc to the low level read_lut() funcs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The low level read_lut() functions don't need the entire crtc state
as they know exactly what they're reading. Just need to pass in the
crtc to get at the pipe. This now neatly mirrors the load_lut()
direction.

Subject: drm/i915: Lock gmbus/aux mutexes while changing cdclk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gmbus/aux may be clocked by cdclk, thus we should make sure no
transfers are ongoing while the cdclk frequency is being changed.
We do that by simply grabbing all the gmbus/aux mutexes. No one
else should be holding any more than one of those at a time so
the lock ordering here shouldn't matter.

v2: Use mutex_lock_nest_lock() (Chris)

Now the DW-HDMI Controller supports the HDMI2.0 modes, enable support
for these modes in the connector if the platform supports them.
We limit these modes to DW-HDMI IP version >= 0x200a which
are designed to support HDMI2.0 display modes.

Subject: drm/meson: venc: add support for YUV420 setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds encoding support for the YUV420 output from the
Amlogic Meson SoCs Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.

In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.

Subject: drm/meson: vclk: add support for YUV420 setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds clocking support for the YUV420 output from the
Amlogic Meson SoCs Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.

This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.

This patch adds the TMDS PHY clock value in all the video clock setup
in order to better support these specific uses cases and switch
to the Common Clock framework for clocks handling in the future.

Subject: drm/meson: Add YUV420 output support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds support for the YUV420 output from the Amlogic Meson SoCs
Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.
In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.

This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.

This patch enables the bridge bus format negociation, and handles
the YUV420 case if selected by the negociation.

Subject: drm/mm: Remove redundant assignment in drm_mm_reserve_node

In Pete Goodliffe words, "You can improve a system by adding new code. You
can also improve a system by removing code" - In this case, commit
"202b52b7fbf70" added new code to initialize end of the node. So, there
is no need for duplicated initialization, and this patch simply removes it.

Subject: drm/i915: Improve the start alignment of bonded pairs

Always wait on the start of the signaler request to reduce the problem
of dequeueing the bonded pair too early -- we want both payloads to
start at the same time, with no latency, and yet still allow others to
make full use of the slack in the system. This reduce the amount of time
we spend waiting on the semaphore used to synchronise the start of the
bonded payload.

Subject: drm/panel-simple: Fix dotclock for Ortustech COM37H3M
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The currently listed dotclock disagrees with the currently
listed vrefresh rate. Change the dotclock to match the vrefresh.

There are two variants of the COM37H3M panel.
The older one's COM37H3M05DTC data sheet specifies:

                         MIN      TYP     MAX
CLK frequency    fCLK     --       22.4    26.3 MHz (in VGA mode)
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv       --      650      --   H
HSYNC frequency  fHSYNC   --       39.3    --   kHz
HSYNC cycle time th       --      570      --   CLK

The newer one's COM37H3M99DTC data sheet says:

                         MIN      TYP     MAX
CLK frequency    fCLK     18       19.8    27   MHz
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv      646      650     700   H
HSYNC frequency  fHSYNC  --        39.0    50.0 kHz
HSYNC cycle time th      504      508     630   CLK

So we choose a parameter set that lies within the specs
of both variants. We start at .vrefresh = 60,
choose .htotal = 570 and .vtotal = 650 and end up
in a clock of 22.230 MHz.

Subject: drm/dp_mst: Make drm_dp_mst_dpcd_write() consistent with
 drm_dp_dpcd_write()

Noticed this while having some problems with hubs sometimes not being
detected on the first plug. Every single dpcd read or write function
returns the number of bytes transferred on success or a negative error
code, except apparently for drm_dp_mst_dpcd_write() - which returns 0 on
success.

There's not really any good reason for this difference that I can tell,
and having the two functions give differing behavior means that
drm_dp_dpcd_write() will end up returning 0 on success for MST devices,
but the number of bytes transferred for everything else.

So, fix that and update the kernel doc.

Subject: drm/dp_mst: Fix drm_dp_check_mstb_guid() return code

We actually expect this to return a 0 on success, or negative error code
on failure. In order to do that, we check whether or not we managed to
write the whole GUID and then return 0 if so, otherwise return a
negative error code. Also, let's add an error message here so it's a
little more obvious when this fails in the middle of a link address
probe.

This should fix issues with certain MST hubs seemingly stopping for no
reason in the middle of the link address probe process.

+description: |
+  The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
+  A dual-LVDS interface is a dual-link connection with even pixels traveling
+  on one link, and with odd pixels traveling on the other link.
+
+  The panel expects odd pixels on the first port, and even pixels on the
+  second port, therefore the ports must be marked accordingly (with either
+  dual-lvds-odd-pixels or dual-lvds-even-pixels).

Subject: drm/amdkfd: Consolidate duplicated bo alloc flags

ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*,
but they are interweavedly used in kernel driver, resulting in bad
readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is not
referenced in kernel, and it functions implicitly in kernel through
ALLOC_MEM_FLAGS_COHERENT, causing unnecessary confusion.

Replace all occurrences of ALLOC_MEM_FLAGS_* with
KFD_IOC_ALLOC_MEM_FLAGS_* to solve the problem.

Only kernel bo has kfd eviction fence.
This warning is to give a notice that kfd only remove eviction fence on
individual bos.

Subject: drm/i915/mst: Hookup DRM DP MST late_register/early_unregister
 callbacks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

i915 can enable aux device nodes for DP MST by calling
drm_dp_mst_connector_late_register()/
drm_dp_mst_connector_early_unregister(),
so let's hook that up.

Changes since v1:
* Call intel_connector_register/unregister() from
  intel_dp_mst_connector_late_register/unregister() so we don't lose
  error injection - Ville Syrjälä
Changes since v2:
* Don't forget to clean up if intel_connector_register() fails - Ville

Subject: drm/i915/display: Deactive FBC in fastsets when disabled by parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most of the kms_frontbuffer_tracking tests disables the feature being
tested, draw, get the CRC then enable the feature, draw again, get the
CRC and check if it matches.
Some times it is able to do that with a fastset, so
intel_pre_plane_update() is executed but intel_fbc_can_flip_nuke() was
not checking if FBC is now enabled in this CRTC leaving FBC active and
causing the warning bellow in __intel_fbc_disable()

Subject: drm/i915: Defer semaphore priority bumping to a workqueue

Since the semaphore fence may be signaled from inside an interrupt
handler from inside a request holding its request->lock, we cannot then
enter into the engine->active.lock for processing the semaphore priority
bump as we may traverse our call tree and end up on another held
request.

Subject: drm/rockchip: rgb: don't count non-existent devices when determining
 subdrivers

rockchip_drm_endpoint_is_subdriver() may also return error codes.
For example if the target-node is in the disabled state, so no
platform-device is getting created for it.

In that case current code would count that as external rgb device,
which in turn would make probing the rockchip-drm device fail.

So only count the target as rgb device if the function actually
returns 0.

The two files have been duplicated under the gt/ subdir and since there
are not apparent users looking for them at the old location lets simply
remove them and duplicated code.

Subject: drm/i915/hotplug: convert to drm_device based logging.

Converts various instances of the printk based drm logging macros to the
struct drm_device based logging macros in i915/display/intel_hotplug.c.
In some cases, this involves extracting the drm_i915_private pointer from
the drm_device struct to be used in the logging macros.

Subject: drm/i915/lvds: convert to drm_device based logging macros.

Converts various instances of the printk based drm logging macros to the

This transformation was done by the following coccinelle script that
matches based on the existence of a drm_i915_private device:

Subject: drm/i915/gt: Use scnprintf() for avoiding potential buffer overflow

Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

v2: Mark all reads and writes of rpm->pm_events.

The flow of enabling/disabling rps is stronly ordered, so the writes and
interrupt generation are also strongly ordered -- just this may not be
visible to the compiler, so provide annotations.

Subject: drm/edid: Add function to parse EDID descriptors for monitor range
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adaptive Sync is a VESA feature so add a DRM core helper to parse
the EDID's detailed descritors to obtain the adaptive sync monitor range.
Store this info as part fo drm_display_info so it can be used
across all drivers.
This part of the code is stripped out of amdgpu's function
amdgpu_dm_update_freesync_caps() to make it generic and be used
across all DRM drivers

v6:
* Call it monitor_range (Ville)
v5:
* Use the renamed flags
v4:
* Use is_display_descriptor() (Ville)
* Name the monitor range flags (Ville)
v3:
* Remove the edid parsing restriction for just DP (Nicholas)
* Use drm_for_each_detailed_block (Ville)
* Make the drm_get_adaptive_sync_range function static (Harry, Jani)
v2:
* Change vmin and vmax to use u8 (Ville)
* Dont store pixel clock since that is just a max dotclock
and not related to VRR mode (Manasi)

Subject: drm: Register connector instead of calling register_connector
 callback

drm_dp_mst_topology_mgr_cbs.register_connector callbacks are literally
identical amongst every driver and don't do anything other than
calling drm_connector_register(). Hence call drm_connector_register()
directly instead of a callback.

This is the preparatory step for removing the
drm_dp_mst_topology_mgr_cbs.register_connector callback hook.

Subject: drm: Remove dp mst register connector callbacks

drm_dp_mst_port_add_connector() directly calls the
drm_connector_register() now and
drm_dp_mst_topology_mgr_cbs.register_connector callback is not getting

Hence remove all drm_dp_mst_topology_mgr_cbs.register_connector
callbacks.

This is the preparatory step for removing the

The removal is done with below sementic patch:

drm_dp_mst_topology_mgr_cbs.destroy_connector callbacks are identical
amongst every driver and don't do anything other than cleaning up the
connector (drm_connector_unregister()/drm_connector_put()) except for
amdgpu_dm driver where some amdgpu_dm specific code in there which I
an not sure if it should stay or not.

Create and use a helper which calls driver's destroy_connector hook if
available otherwise does cleanup internally.

This is the step towards removing identical hooks from every driver.

Subject: drm/i915/gem: Take a copy of the engines for context_barrier_task

When applying the context-barrier, we only care about the current
engines, as the next set of engines will be naturally after the barrier.
So we can skip holding the ctx->engines_mutex while constructing the
request by taking a sneaky reference to the i915_gem_engines instead.

Subject: drm/vmwgfx: Fix the refuse_dma mode when using guest-backed objects

When we refuse DMA from system pages for whatever reason, we don't
handle that correctly when guest-backed objects was enabled.
Since guest-backed objects by definition require DMA to and from
system pages, disable all functionality that relies on them.
That basically amounts to 3D acceleration and screen targets.

TTM doesn't yet fully support mapping of DMA memory when SEV is active,
so in that case, refuse DMA operation. For guest-backed object operation
this means 3D acceleration will be disabled. For host-backed, VRAM will be
used for data transfer between the guest and the device.

Subject: drm/vmwgfx: Drop preempt_disable() in vmw_fifo_ping_host()

vmw_fifo_ping_host() disables preemption around a test and a register
write via vmw_write(). The write function acquires a spinlock_t typed
lock which is not allowed in a preempt_disable()ed section on
PREEMPT_RT. This has been reported in the bugzilla.

It has been explained by Thomas Hellstrom that this preempt_disable()ed
section is not required for correctness.

Remove the preempt_disable() section.

I noticed that there is a prototype for vmw_fifo_ping_host_locked() but
no function. Then I looked further and noticed more functions which are
not used anymore or functions protoypes which remained after the
function was removed.

Remove unused function (prototypes).

Subject: drm/i915/gem: Drop relocation slowpath

Since the relocations are no longer performed under a global
struct_mutex, or any other lock, that is also held by pagefault handlers,
we can relax and allow our fast path to take a fault. As we no longer
need to abort the fast path for lock avoidance, we no longer need the
slow path handling at all.

Subject: drm/i915/gt: Wait for RCUs frees before asserting idle on unload

During driver unload, we have many asserts that we have released our
bookkeeping structs and are idle. In some cases, these struct are
protected by RCU and we do not release them until after an RCU grace
period.

Subject: Revert "drm/i915/tgl: Add extra hdc flush workaround"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit 36a6b5d964d995b536b1925ec42052ee40ba92c4.

The commit takes care Wa_1604544889 which was fixed on a0 stepping based on
a0 replan. So no SW workaround is required on any stepping now.

Subject: drm/amdgpu: update ras capability's query based on mem ecc
 configuration

RAS support capability needs to be updated on top of different
memeory ECC enablement, and remove redundant memory ecc check
in gmc module for vega20 and arcturus.

v2: check HBM ECC enablement and set ras mask accordingly.
v3: avoid to invoke atomfirmware interface to query twice.

Fix the warning
"warn: variable dereferenced before check 'obj' (see line 1131)"
by removing unnecessary checks as amdgpu_ras_debugfs_create_all()
is only called from amdgpu_debugfs_init() where obj member in
con->head list is not NULL.
Use list_for_each_entry() instead list_for_each_entry_safe() as obj
do not to be freeing or removing from list during this process.

Fix the Kconfig dependencies so that the menu is presented
correctly by adding a dependency on DRM_AMDGPU to the "menu"
Kconfig statement.  This makes a continuous dependency on
DRM_AMDGPU in the DRM AMD menus and eliminates a broken menu
structure.

Subject: drm/amd/display: clean up a condition in dmub_psr_copy_settings()

We can remove the NULL check for "res_ctx" and
"res_ctx->pipe_ctx[i].stream->link".  Also it's nicer to align the
conditions using spaces so I re-indented a bit.

Longer explanation: The "res_ctx" pointer points to an address in the
middle of a struct so it can't be NULL.  For
"res_ctx->pipe_ctx[i].stream->link" we know that it is equal to "link"
and "link" is non-NULL.

Subject: drm/amd/display: Possible divide by zero in set_speed()

If "speed" is zero then we use it as a divisor to find "prescale".  It's
better to move the check for zero to the very start of the function.

Subject: drm/amdgpu: Stop using the DRIVER debugging flag for vblank debugging
 messages

These are some very loud debug statements that get printed on every
vblank when driver level debug printing is enabled in DRM, and doesn't
really tell us anything that isn't related to vblanks. So let's move
this over to the proper debug flag to be a little less spammy with our
debug output.

Subject: drm/amd/display: Add link_rate quirk for Apple 15" MBP 2017

This fixes a problem found on the MacBookPro 2017 Retina panel:

The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec aka LINK_RATE_RBR2
aka 0xc), but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.

This restricts the panel to 8 bpc, not providing the full
color depth of the panel on Linux <= 5.5. Additionally, commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")'
introduced into Linux 5.6-rc1 will unclamp panel depth to
its full 10 bpc, thereby requiring a eDP bandwidth for all
modes that exceeds the bandwidth available and causes all modes
to fail validation -> No modes for the laptop panel -> failure
to set any mode -> Panel goes dark.

This patch adds a quirk specific to the MBP 2017 15" Retina
panel to override reported max link rate to the correct maximum
of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display
precision.

Please apply for Linux 5.6+ to avoid regressing Apple MBP panel
support.

Subject: drm/scheduler: fix inconsistent locking of job_list_lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1db8c142b6c5 (drm/scheduler: Add drm_sched_suspend/resume_timeout()) made
the job_list_lock IRQ safe in as the suspend/resume calls were expected to
be called from IRQ context. This usage never materialized in upstream.
Instead amdgpu started locking the job_list_lock in an IRQ unsafe way in
amdgpu_ib_preempt_mark_partial_job() and amdgpu_ib_preempt_job_recovery(),
which leads to potential deadlock if one would actually start to call the
drm_sched_suspend/resume_timeout functions from IRQ context.

As no current user needs the locking to be IRQ safe, the local IRQ
disable/enable is pure overhead. Fix the inconsistent locking by changing
all uses of job_list_lock to use the IRQ unsafe locking primitives.

On gen11 the XY_FAST_COPY_BLT command has some size restrictions on its

uses it to copy object contents during some selftests, so let's ensure
the restrictions are followed.

The bspec description for this workaround tells us to program
0xFFFF_FFFF into both FBC_RT_BASE_ADDR_REGISTER_* registers, but we've
previously found that this leads to failures in CI.  Our suspicion is
that the failures are caused by this valid turning on the "address valid
bit" even though we're intentionally supplying an invalid address.
Experimentation has shown that setting all bits _except_ for the
RT_VALID bit seems to avoid these failures.

v2:
 - Mask off the RT_VALID bit.  Experimentation with CI trybot indicates
   that this is necessary to avoid reset failures on BCS.

v3:
 - Program RT_BASE before RT_BASE_UPPER so that the valid bit is turned
   off by the first write.  (Chris)

Subject: drm/i915: Add Wa_1605460711 / Wa_1408767742 to ICL and EHL

This workaround appears under two different numbers (and with somewhat
confused stepping applicability on ICL).  Ultimately it appears we
should just implement this for all stepping of ICL and EHL.

Note that this is identical to Wa_1407928979:tgl that already exists in
our driver too...yet another number referencing the same actual
workaround.

Subject: drm/tegra: dc: Silence RGB output deferred-probe error

Driver fails to probe with -EPROBE_DEFER if display output isn't ready
yet. This produces a bit noisy error message in KMSG during kernel's boot
up on Tegra20 and Tegra30 because RGB output tends to be probed earlier
than a corresponding voltage regulator driver.

Subject: drm/dp_mst: Convert drm_dp_mst_topology_mgr.is_waiting_for_dwn_reply
 to bitfield

Small nitpick that I noticed a second ago - we can save some space in
the struct by making this a bitfield and sticking it with the rest of
the bitfields. Also, some small cleanup to the kdocs for this member.

There should be no functional changes in this patch.

Subject: drm/i915/tgl: Remove require_force_probe protection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have a few TGL machines in our CI and it is mostly green with
failures in tests that will not impact future Linux installations.
Also there is no warnings, errors, flickering or any visual defects
while doing ordinary tasks like browsing and editing documents in a
dual monitor setup.

As a reminder i915.require_force_probe was created to protect
future Linux installation's iso images that might contain a
kernel from the enabling time of the new platform. Without this
protection most of linux installation was recommending
nomodeset option during installation that was getting stick
there after installation.

Subject: dt-bindings: display: fix panel warnings

Fix following type af warnings in the panel bindings:

Warning (unit_address_vs_reg): /example-0/dsi/panel: node has a reg or ranges property, but no unit name
Warning (unit_address_vs_reg): /example-0/dsi@ff450000: node has a unit name, but no reg property

Removing the "@xxx" from the node name fixed first warning.
Adding a missing reg property fixed the second warning

v2:
  - renamed mdss_dsi to dsi in panel-simple-dsi.yaml (Rob)

Subject: drm/vmwgfx: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

[2] https://github.com/KSPP/linux/issues/21

Subject: drm/edid: Distribute switch variables for initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.

To avoid these problems, lift such variables up into the next code
block.

Subject: drm/amdgpu: revise RLCG access path

what changed:
1)provide new implementation interface for the rlcg access path
2)put SQ_CMD/SQ_IND_INDEX to GFX9 RLCG path to let debugfs's reg_op
function can access reg that need RLCG path help

now even debugfs's reg_op can used to dump wave.

Subject: drm/amdgpu: Move EEPROM I2C adapter to amdgpu_device

Puts the i2c adapter in common place for sharing by RAS
and upcoming data read from FRU EEPROM feature.

v2:
Move i2c adapter to amdgpu_pm and rename it.

v3: Move i2c adapter init to ASIC specific code and get rid
of the switch case in amdgpu_device

Subject: drm/sched: implement and export drm_sched_pick_best
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove drm_sched_entity_get_free_sched() and use the logic of picking
the least loaded drm scheduler from a drm scheduler list to implement
drm_sched_pick_best(). This patch also exports drm_sched_pick_best() so
that it can be utilized by other drm drivers.

Subject: drm/amdgpu: disable gpu_sched load balancer for vcn jobs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VCN HW doesn't support dynamic load balance on multiple instances
for a context. This patch initializes VNC entities with only one
drm_gpu_scheduler picked by drm_sched_pick_best(). Picking a
drm_gpu_scheduler using drm_sched_pick_best() ensures that we
do load balance among multiple contexts but not among multiple
jobs in a context.

Subject: drm/amd/display: Remove redundant hdcp display state

[Why]
Due to previous code changes displays which are in active state
immediately transition to the active and added state. This makes the two
states redundant and unnecessary.

[How]
Instead of updating the device state to active and added after
successful addition, change state to inactive if addition failed. Also,
change references to active and added state to just added state.

Subject: drm/amd/display: workaround for HDMI hotplug in DPMSOFF state

[Why]
When hotplug a HDMI monitor during entering S0i3 or DPMSOFF state due to
entering infinite loop when calling vbios to program pixel clocks. In
this scenario, pll is enabled but phy is not, and there is not a
programing guide for this case.

[How]
Before we having the proper programing guide, before disable pll, doing
a phy enable and disable to avoid the issue.

Subject: drm/amd/display: fix split threshold w/a to work with mpo

Right now only stream count is used to avoid split.  This change updates
the W/A to check plane count instead.

Subject: drm/amd/display: Pass triplebuffer surface flip flags down to plane
 state

[Why]
A "dcn20_program_front_end_for_ctx" warning is observed on Renoir.

Since the resource definition doesn't explicitly disable triplebuffer
flips like Navi10 DC actually attempts to go and setup triplebuffering
even when we pass in false to the plane state.

If we hit a full update after triplebuffering has been setup we see the
assertion since we don't expect full updates while performing
triplebuffer flips.

Normally this would get reset back to false whne we pass in the new
plane state, but since we never actually copy the flag when doing
surface updates this doesn't happen.

[How]
Copy the flag onto the plane update based on the requested surface
update state.

Subject: drm/amd/display: Explicitly disable triplebuffer flips

[Why]
This is enabled by default on Renoir but there's userspace/API support
to actually make use of this.

Since we're not passing this down through surface updates, let's
explicitly disable this for now.

This fixes "dcn20_program_front_end_for_ctx" warnings associated with
incorrect/unexpected programming sequences performed while this is
enabled.

[How]
Disable it at the topmost level in DM in case anyone tries to flip this
to enabled for any of the other ASICs like Navi10/14.

[Why]
The PSR enablement was dependent on swizzle as a workaround for
non-pageflipping fb console. It's no longer required.

[How]
Remove PSR-enable dependency on swizzle mode.

Subject: drm/amd/display: remove magic numbers in hdcp_ddc

[why]
DP doesn't have message id as the first byte of an hdcp message,
current hdcp psp unifies HDMI and DP message so that it is required
when reading DP HDCP messages in hdcp_ddc, a message id needs to be
added as the first byte of the HDCP message.
The id is currently assigned as a magic number which is not a good
coding practice.

[how]
Replace magic numbers with macro defined in hdcp headers.

Subject: drm/amd/display: combine watermark change and clock change for update
 clocks.

[Why]
underflow happened when playing video on 1366x768 + 4K clone mode due to
incorrect handle watermark change flag and lower down clocks to early.

[How]
Check watermark change flag when decide doing optimized, and check
optimized required flag to do clock update.

Subject: drm/amd/display: DPP DTO isn't update properly.

[Why]
before update dpp DTO, we check dppclks in context to determine it is
changed or not, but dppclks in context will be updated anyways after
flip is done, so compare dppclks in context will always get an equal
result.

[How]
Add pipe dpp clks in dccg and compare values between dccg and context.

Subject: drm/amd/display: Allocate scratch space for DMUB CW7

[Why]
The scratch space can be used to pass data between x86 and DMCUB.  DMCUB
will manage the actually mapping of CW7 internally, driver does not
program the window.

[How]
Allocate extra space within the DMUB service's framebuffer for this
scratch space and expose them from the service for use in DC.

Subject: drm/amdgpu: miss PRT case when bo update
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Originally, only the PTE valid is taken in consider.
The PRT case is missied when bo update which raise problem.
We need add condition for PRT case.

v2: add PRT condition for amdgpu_vm_bo_update_mapping, too
v3: fix one typo error

Subject: drm/amdgpu: Remove unnecessary variable shadow in gfx_v9_0_rlcg_wreg

false [-Wsometimes-uninitialized]
        if (offset == grbm_cntl || offset == grbm_idx)

its condition is always true
        if (offset == grbm_cntl || offset == grbm_idx)
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c:738:13: note: initialize the
variable 'shadow' to silence this warning
        bool shadow;
                   ^
                    = 0
1 warning generated.

shadow is only assigned in one condition and used as the condition for
another if statement; combine the two if statements and remove shadow
to make the code cleaner and resolve this warning.

Subject: drm/msm/dpu: Refactor resource manager

Track hardware resource objects in arrays rather than
a list and remove the resource manager's iterator idiom. Separate
the mapping of hardware resources to an encoder ID into a different
array.

Use an implicit mapping between the hardware blocks' ids, which
are 1-based, and array indices in these arrays to replace iteration
with index lookups in several places.

From de3916c70a24e3e1bdbf6b0a77d75b069d8953d9 Mon Sep 17 00:00:00 2001
From: Drew Davenport <ddavenport@chromium.org>
Date: Wed, 19 Feb 2020 10:42:27 -0700
Subject: drm/msm/dpu: Track resources in global state

Move mapping of resources to encoder ids from the resource manager to a
new dpu_global_state struct. Store this struct in global atomic state.

Before this patch, atomic test would be performed by modifying global
state (resource manager), and backing out any changes if the test fails.
By using drm atomic global state, this is not necessary as any changes
to the global state will be discarded if the test fails.

Subject: drm/msm: avoid double-attaching hdmi/edp bridges

Each of hdmi and edp are already attached in msm_*_bridge_init. A second
attachment returns -EBUSY, failing the driver load.

Tested with HDMI on IFC6410 (APQ8064 / MDP4), but eDP case should be
analogous.

Subject: drm/msm/msm_gem.h: Replace zero-length array with flexible-array
 member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

[2] https://github.com/KSPP/linux/issues/21

Subject: drm/msm/a5xx: Always set an OPP supported hardware value

If the opp table specifies opp-supported-hw as a property but the driver
has not set a supported hardware value the OPP subsystem will reject
all the table entries.

Set a "default" value that will match the default table entries but not
conflict with any possible real bin values. Also fix a small memory leak
and free the buffer allocated by nvmem_cell_read().

Subject: dt-bindings: display: msm: gmu: move sram property to gpu bindings

The sram property was incorrectly added to the GMU binding when it
really belongs with the GPU binding instead. Let's go ahead and
move it.

While changes are being made here, let's update the sram property
description to mention that this property is only valid for a3xx and
a4xx GPUs. The a3xx/a4xx example in the GPU is replaced with what was
in the GMU.

Subject: drm/i915/perf: Invalidate OA TLB on when closing perf stream

On running several back to back perf capture sessions involving closing
and opening the perf stream, invalid OA reports are seen in the
beginning of the OA buffer in some sessions. Fix this by invalidating OA
TLB when the perf stream is closed or disabled on gen12.

Convert display/msm/gmu.txt to display/msm/gmu.yaml and remove the old

Subject: drm/msm/a6xx: Use the DMA API for GMU memory objects

The GMU has very few memory allocations and uses a flat memory space so
there is no good reason to go out of our way to bypass the DMA APIs which
were basically designed for this exact scenario.

v7: Check return value of dma_set_mask_and_coherent
v4: Use dma_alloc_wc()
v3: Set the dma mask correctly and use dma_addr_t for the iova type
v2: Pass force_dma false to of_dma_configure to require that the DMA
region be set up and return error from of_dma_configure to fail probe.

Subject: drm/etnaviv: request pages from DMA32 zone when needed

Some Vivante GPUs are found in systems that have interconnects restricted
to 32 address bits, but may have system memory mapped above the 4GB mark.
As this region isn't accessible to the GPU via DMA any GPU memory allocated
in the upper part needs to go through SWIOTLB bounce buffering. This kills
performance if it happens too often, as well as overrunning the available
bounce buffer space, as the GPU buffer may stay mapped for a long time.

Avoid bounce buffering by checking the addressing restrictions. If the
GPU is unable to access memory above the 4GB mark, request our SHM buffers
to be located in the DMA32 zone.

Subject: drm/etnaviv: fix TS cache flushing on GPUs with BLT engine

As seen in the Vivante kernel driver, most GPUs with the BLT engine have
a broken TS cache flush. The workaround is to temporarily set the BLT
command to CLEAR_IMAGE, without actually executing the clear. Apparently
this state change is enough to trigger the required TS cache flush. As
the BLT engine is completely asychronous, we also need a few more stall
states to synchronize the flush with the frontend.

Subject: drm/vmwgfx: Also check for SVGA_CAP_DX before reading DX context
 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Virtual device consider SVGA_CAP_DX and SVGA3D_DEVCAP_DXCONTEXT
independent of each other. Some of the commands in cmd_buf depends on
SVGA_CAP_DX, so better to check for that as well.

Subject: drm/vmwgfx: Sync legacy multisampling device capability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In favor of SM4.1 multisampling capability, virtual device deprecated
old multisampling device capability. Mark legacy multisampling device
capability as dead. Rename the function that masks legacy multisample
capability to reflect that now it is masking a deprecated feature.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of having different bool in device private to represent
incremental graphics context capabilities, add a new sm type enum.

v2: Use enum instead of bit flag.

v3: Incorporated review comments.

  * FIFO Synchronization Registers
  *
- *  This explains the relationship between the various FIFO
- *  sync-related registers in IOSpace and in FIFO space.
- *
  *  SVGA_REG_SYNC --
  *
- *       The SYNC register can be used in two different ways by the guest:
- *
- *         1. If the guest wishes to fully sync (drain) the FIFO,
- *            it will write once to SYNC then poll on the BUSY
- *            register. The FIFO is sync'ed once BUSY is zero.
- *
- *         2. If the guest wants to asynchronously wake up the host,
- *            it will write once to SYNC without polling on BUSY.
- *            Ideally it will do this after some new commands have
- *            been placed in the FIFO, and after reading a zero
- *            from SVGA_FIFO_BUSY.
- *
- *       (1) is the original behaviour that SYNC was designed to
- *       support.  Originally, a write to SYNC would implicitly
- *       trigger a read from BUSY. This causes us to synchronously
- *       process the FIFO.
- *
- *       This behaviour has since been changed so that writing SYNC
- *       will *not* implicitly cause a read from BUSY. Instead, it
- *       makes a channel call which asynchronously wakes up the MKS
- *       thread.
- *
- *       New guests can use this new behaviour to implement (2)
- *       efficiently. This lets guests get the host's attention
- *       without waiting for the MKS to poll, which gives us much
- *       better CPU utilization on SMP hosts and on UP hosts while
- *       we're blocked on the host GPU.
- *
- *       Old guests shouldn't notice the behaviour change. SYNC was
- *       never guaranteed to process the entire FIFO, since it was
- *       bounded to a particular number of CPU cycles. Old guests will
- *       still loop on the BUSY register until the FIFO is empty.
- *
- *       Writing to SYNC currently has the following side-effects:
- *
- *         - Sets SVGA_REG_BUSY to TRUE (in the monitor)
- *         - Asynchronously wakes up the MKS thread for FIFO processing
- *         - The value written to SYNC is recorded as a "reason", for
- *           stats purposes.
- *
- *       If SVGA_FIFO_BUSY is available, drivers are advised to only
- *       write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
- *       SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
- *       eventually set SVGA_FIFO_BUSY on its own, but this approach
- *       lets the driver avoid sending multiple asynchronous wakeup
- *       messages to the MKS thread.
+ *       The SYNC register can be used by the guest driver to signal to the
+ *       device that the guest driver is waiting for previously submitted
+ *       commands to complete.
+ *
+ *       When the guest driver writes to the SYNC register, the device sets
+ *       the BUSY register to TRUE, and starts processing the submitted commands
+ *       (if it was not already doing so).  When all previously submitted
+ *       commands are finished and the device is idle again, it sets the BUSY
+ *       register back to FALSE.  (If the guest driver submits new commands
+ *       after writing the SYNC register, the new commands are not guaranteed
+ *       to have been procesesd.)
+ *
+ *       When guest drivers are submitting commands using the FIFO, the device
+ *       periodically polls to check for new FIFO commands when idle, which may
+ *       introduce a delay in command processing.  If the guest-driver wants
+ *       the commands to be processed quickly (which it typically does), it
+ *       should write SYNC after each batch of commands is committed to the
+ *       FIFO to immediately wake up the device.  For even better performance,
+ *       the guest can use the SVGA_FIFO_BUSY register to avoid these extra
+ *       SYNC writes if the device is already active, using the technique known
+ *       as "Ringing the Doorbell" (described below).  (Note that command
+ *       buffer submission implicitly wakes up the device, and so doesn't
+ *       suffer from this problem.)
+ *
+ *       The SYNC register can also be used in combination with BUSY to
+ *       synchronously ensure that all SVGA commands are processed (with both
+ *       the FIFO and command-buffers).  To do this, the guest driver should
+ *       write to SYNC, and then loop reading BUSY until BUSY returns FALSE.
+ *       This technique is known as a "Legacy Sync".
  *
  *  SVGA_REG_BUSY --
  *
  *       This register is set to TRUE when SVGA_REG_SYNC is written,
- *       and it reads as FALSE when the FIFO has been completely
- *       drained.
- *
- *       Every read from this register causes us to synchronously
- *       process FIFO commands. There is no guarantee as to how many
- *       commands each read will process.
+ *       and is set back to FALSE when the device has finished processing
+ *       all commands and is idle again.
  *
- *       CPU time spent processing FIFO commands will be billed to
- *       the guest.
+ *       Every read from the BUSY reigster will block for an undefined
+ *       amount of time (normally until the device finishes some interesting
+ *       work unit), or the device is idle.
  *
- *       New drivers should avoid using this register unless they
- *       need to guarantee that the FIFO is completely drained. It
- *       is overkill for performing a sync-to-fence. Older drivers
- *       will use this register for any type of synchronization.
+ *       Guest drivers can also do a partial Legacy Sync to check for some
+ *       particular condition, for instance by stopping early when a fence
+ *       passes before BUSY has been set back to FALSE.  This is particularly
+ *       useful if the guest-driver knows that it is blocked waiting on the
+ *       device, because it will yield CPU time back to the host.
  *
  *  SVGA_FIFO_BUSY --
  *
- *       This register is a fast way for the guest driver to check
- *       whether the FIFO is already being processed. It reads and
- *       writes at normal RAM speeds, with no monitor intervention.
- *
- *       If this register reads as TRUE, the host is guaranteeing that
- *       any new commands written into the FIFO will be noticed before
- *       the MKS goes back to sleep.
+ *       The SVGA_FIFO_BUSY register is a fast way for the guest driver to check
+ *       whether the device is actively processing FIFO commands before writing
+ *       the more expensive SYNC register.
  *
- *       If this register reads as FALSE, no such guarantee can be
- *       made.
+ *       If this register reads as TRUE, the device is actively processing
+ *       FIFO commands.
  *
- *       The guest should use this register to quickly determine
- *       whether or not it needs to wake up the host. If the guest
- *       just wrote a command or group of commands that it would like
- *       the host to begin processing, it should:
+ *       If this register reads as FALSE, the device may not be actively
+ *       processing commands, and the guest driver should try
+ *       "Ringing the Doorbell".
  *
- *         1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
- *            action is necessary.
+ *       To Ring the Doorbell, the guest should:
  *
- *         2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
- *            code that we've already sent a SYNC to the host and we
- *            don't need to send a duplicate.
+ *       1. Have already written their batch of commands into the FIFO.
+ *       2. Check if the SVGA_FIFO_BUSY register is available by reading
+ *          SVGA_FIFO_MIN.
+ *       3. Read SVGA_FIFO_BUSY.  If it reads as TRUE, the device is actively
+ *          processing FIFO commands, and no further action is necessary.
+ *       4. If SVGA_FIFO_BUSY was FALSE, write TRUE to SVGA_REG_SYNC.
  *
- *         3. Write a reason to SVGA_REG_SYNC. This will send an
- *            asynchronous wakeup to the MKS thread.
+ *       For maximum performance, this procedure should be followed after
+ *       every meaningful batch of commands has been written into the FIFO.
+ *       (Normally when the underlying application signals it's finished a
+ *       meaningful work unit by calling Flush.)

Subject: drm/vmwgfx: Add support for UA view commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Virtual device now support new commands to manage unordered access
views. Allow them as part of user-space command buffer. This involves
adding UA view cotable, binding tracker info, new view type and command
verifier functions.

v2: fix comment typo
v3: style fixes (don't use deprecated PTR_RET)

Subject: drm/vmwgfx: Rename stream output target binding tracker struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous name vmw_ctx_bindinfo_so is misleading because it actually
represent so target and stream output is a new resource type that needs
tracking for SM5 capable device. Also rename binding type enum and
internal functions to reflect these belongs to so targets.

From e8bead9c5c07497ce42d684729738f042896a237 Mon Sep 17 00:00:00 2001
From: Deepak Rawat <drawat.floss@gmail.com>
Date: Thu, 13 Dec 2018 14:04:31 -0800
Subject: drm/vmwgfx: Add support for streamoutput with mob commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With SM5 capability a new version of streamoutput is supported by device
which need backing mob and a new field. With this change the new command
is supported in command buffer.

v2: Also track streamoutput context binding in binding manager.

v3: Track only one streamoutput as only one can be set to context.
v4: Fix comment typos

Subject: drm/vmwgfx: Split surface metadata from struct vmw_surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Create a new structure vmw_surface_metadata representing the metadata
used for creating surface. With this can make the surface_define_priv
a bit cleaner.

Subject: drm/vmwgfx: Refactor surface_define to use vmw_surface_metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Makes surface_define cleaner by sending vmw_surface_metadata instead of
all the arguments individually.

v2: fix uninitialized return value, error message

Subject: drm/vmwgfx: Add surface define v4 command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Surface define v4 added new member buffer_byte_stride. With this patch
add buffer_byte_stride in surface metadata and create surface using new
command if support is available.

Also with this patch replace device specific data types with kernel
types.

Subject: drm/amd/display: Fix pageflip event race condition for DCN.

Commit '16f17eda8bad ("drm/amd/display: Send vblank and user
events at vsartup for DCN")' introduces a new way of pageflip
completion handling for DCN, and some trouble.

The current implementation introduces a race condition, which
can cause pageflip completion events to be sent out one vblank
too early, thereby confusing userspace and causing flicker:

prepare_flip_isr():

1. Pageflip programming takes the ddev->event_lock.
2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED
3. Releases ddev->event_lock.

--> Deadline for surface address regs double-buffering passes on
    target pipe.

4. dc_commit_updates_for_stream() MMIO programs the new pageflip
   into hw, but too late for current vblank.

=> pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete
   in current vblank due to missing the double-buffering deadline
   by a tiny bit.

5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires,
   dm_dcn_crtc_high_irq() gets called.

6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the
   pageflip has been completed/will complete in this vblank and
   sends out pageflip completion event to userspace and resets
   pflip_status = AMDGPU_FLIP_NONE.

=> Flip completion event sent out one vblank too early.

This behaviour has been observed during my testing with measurement
hardware a couple of time.

The commit message says that the extra flip event code was added to
dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events
in case the pflip irq doesn't fire, because the "DCH HUBP" component
is clock gated and doesn't fire pflip irqs in that state. Also that
this clock gating may happen if no planes are active. This suggests
that the problem addressed by that commit can't happen if planes
are active.

The proposed solution is therefore to only execute the extra pflip
completion code iff the count of active planes is zero and otherwise
leave pflip completion handling to the pflip irq handler, for a
more race-free experience.

Note that i don't know if this fixes the problem the original commit
tried to address, as i don't know what the test scenario was. It
does fix the observed too early pageflip events though and points
out the problem introduced.

There is one one corner case at dma_fence_signal_locked
which will raise the NULL pointer problem just like below.
->dma_fence_signal
    ->dma_fence_signal_locked
	->test_and_set_bit
here trigger dma_fence_release happen due to the zero of fence refcount.

->dma_fence_put
    ->dma_fence_release
	->drm_sched_fence_release_scheduled
	    ->call_rcu
here make the union fled “cb_list” at finished fence
to NULL because struct rcu_head contains two pointer
which is same as struct list_head cb_list

Therefore, to hold the reference of finished fence at drm_sched_process_job
to prevent the null pointer during finished fence dma_fence_signal

Subject: drm/amd/swSMU: add callback to set AC/DC power source (v2)

This is needed to tell the SMU firmware what state is in
in certain cases.  DC mode does not allow overclocking
for example.

v2: split Evan's original patch (Alex)

Subject: drm/i915: Use explicit flag to mark unreachable intel_context

I need to keep the GEM context around a bit longer so adding an explicit
flag for syncing execbuf with closed/abandonded contexts.

v2:
 * Use already available context flags. (Chris)

Subject: drm/i915/gt: Treat idling as a RPS downclock event

If we park/unpark faster than we can respond to RPS events, we never
will process a downclock event after expiring a waitboost, and thus we
will forever restart the GPU at max clocks even if the workload switches
and doesn't justify full power.

Subject: drm/i915: Avoid live-lock with i915_vma_parked()

Abuse^W Take advantage that we know we are inside the GT wakeref and
that prevents any client execbuf from reopening the i915_vma in order to
claim all the vma to close without having to drop the spinlock to free
each one individually. By keeping the spinlock, we do not have to
restart if we run concurrently with i915_gem_free_objects -- which
causes them both to restart continually and make very very slow
progress.

Subject: drm/i915/gt: Select the deepest available parking mode for rc6

On Ivybridge, we can go lower than rc6 to rc6p. And this is required for
Ivybridge to hit the same minimum power consumption as rc6 on other
platforms, so make it so.

v2: Update selftest to include all rc6 residency counters

Note that Andi did mention that we should be converting the magic
numbers into opaque magic macros, so if they ever get reused (unlikely
given only Ivybridge used the extra modes) we'll need to pay back the
technical debt.

Subject: drm/i915/gt: Stage the transfer of the virtual breadcrumb

We move the virtual breadcrumb from one physical engine to the next, if
the next virtual request is scheduled on a new physical engine. Since
the virtual context can only be in one signal queue, we need it to track
the current physical engine for the new breadcrumbs. However, to move
the list we need both breadcrumb locks -- and since we cannot take both
at the same time (unless we are careful and always ensure consistent
ordering) stage the movement of the signaler via the current virtual
request.

Subject: drm/i915/display: Fix mode private_flags comparison at atomic_check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes the private_flags of mode to be checked and
compared against uapi.mode and not from hw.mode. This helps
properly trigger modeset at boot if desired by driver.

It helps resolve audio_codec initialization issues if display
is connected at boot. Initial discussion on this issue has happened
on below thread:
https://patchwork.freedesktop.org/series/74828/

v2: No functional change. Fixed the Closes tag and added
Maarten's RB.

v3: Added Fixes tag.
