Subject: drm/i915: Clean up casts to crtc_state in intel_atomic_commit_tail()

Use old/new_intel_crtc_state, and get rid of all the conversion casts
where they don't add anything.

Subject: drm/i915: Handle cursor updating active_planes correctly, v2.

While we may not update new_crtc_state, we may clear active_planes
if the new cursor update state will disable the cursor, but we fail
after. If this is immediately followed by a modeset disable, we may
soon not disable the planes correctly when we start depending on
active_planes.

Changes since v1:
- Clarify why we cannot swap crtc_state. (Matt)

Subject: drm/i915: Unconditionally clear plane visibility, v2.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We need to assume the plane has been visible before, even if no CRTC
is assigned to the plane. This is because when enabling a nv12 plane
on gen11, we will have to enable an extra plane and make it visible
by marking it in crtc_state->active_planes for
intel_update_planes_on_crtc().

Additionally, clear visible flag in intel_plane_atomic_check, in case
we ever hit a bug with visibility. Our code implicitly assumes that
plane_state->visible is only true when crtc and fb are set,
so we will either null deref in intel_fbc_choose_crtc() or
do something bad during the actual commit which cares even more.

Changes since v1:
- Unconditionally clear crtc_state->active_planes as well.
- Reword commit message, since this is now a preparation patch for
  NV12 Y / UV plane linking.

Subject: drm/i915: Make intel_crtc_disable_planes() use active planes mask.

This will only disable planes we actually had marked as visible in
crtc_state->visible_planes and cleans up intel_crtc_disable_plane()
slightly.

This is also useful for when we start enabling NV12 support for gen11,
in which we will make the separate Y plane visible, but ignore the
Y plane's state.

Subject: drm/i915: Replace call to commit_planes_on_crtc with internal update,
 v2.

drm_atomic_helper_commit_planes_on_crtc calls begin_commit,
then plane_update hooks, then flush_commit. Because we keep our own
visibility tracking through plane_state->visible there's no need to
rely on the atomic hooks for this.

By explicitly writing our own helper, we can update visible planes
as needed, which is useful to make NV12 support work as intended.

Changes since v1:
- Reword commit message. (Matt Roper)
- Rename to intel_update_planes_on_crtc(). (Matt)

Subject: drm/i915: Clean up scaler setup, v2.

On skylake we can switch to a high quality scaler mode when only 1 out
of 2 scalers are used, but on GLK and later bit 28 has a different
meaning. Don't set it, and make clear the distinction between
SKL and later PS values.

Changes since v1:
- Add missing break statement.

We can't make NV12 work any other way. The scaler doesn't handle odd
coordinates well, and we will get visual corruption on the screen.

Subject: drm/i915/icl: DSI vswing programming sequence

This patch setup voltage swing before enabling
combo PHY DDI (shared with DSI).
Note that DSI voltage swing programming is for
high speed data buffers. HW automatically handles
the voltage swing for the low power data buffers.

v2: Rebase
v3: Address various review comments related to VSWING
    programming (Jani N)

we are missing the execlists_submission_tasklet() invocation before the
execlists_reset_fini() implying that either the queue is empty, or we
failed to schedule and run the tasklet on finish. Add an assert so we
are sure that on unsubmitting the incomplete request after reset, the
queue is indeed populated.

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

This cleanup patch makes changes to use for_each_pipe loop
during bit-mask assignment of allowed crtc with encoder.

changes:
 - use BIT(i) macro instead of (1 << i) (Chris)
changes from V2:
 - use int for consistency (Jani)
changes from V3:
 - instead use enum pipe (Ville)
changes from V4:
 - drop DP/HDMI changes, as already part of patch from ville

Subject: drm/i915: Match code to comment and enforce ppgtt for execlists

Our execlist dispatch code requires a ppGTT so make sure we enforce that
option in intel_sanitize_enable_ppgtt(). The comment already tries to
explain that execlists requires ppgtt, but was written when gen8 may
have also taken the legacy path; so rewrite the code to match the
comment by using HAS_EXECLISTS() feature instead of the gen.

Subject: drm/i915: Check fb stride against plane max stride
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit 4e0b83a567e2 ("drm/i915: Extract per-platform plane->check()
functions") removed the plane max stride check for sprite planes.
I was going to add it back when introducing GTT remapping for the
display, but after further thought it seems better to re-introduce
it separately.

So let's add the max stride check back. And let's do it in a nicer
form than what we had before and do it for all plane types (easy
now that we have the ->max_stride() plane vfunc).

Only sprite planes really need this for now since primary planes
are capable of scanning out the current max fb size we allow, and
cursors have more stringent stride checks elsewhere.

In commit 9144d75e22ca ("include/linux/bitops.h: introduce BITS_PER_TYPE"),
we made BITS_PER_TYPE available to all and now we can use the macro to
replace some open-coded computation of sizeof(T) * BITS_PER_BYTE.

/kisskb/src/drivers/gpu/drm/i915/i915_irq.c: warning: 'gu_misc_iir' may be used uninitialized in this function [-Wuninitialized]:  => 3120:10

Silence the compiler warning by ensuring that the local variable is
initialised and removing the guard that is confusing the older gcc.

Subject: drm/i915/runtime_pm: Share code to enable/disable PCH reset handshake
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of have the same code spread into 4 platforms lets share it.
BXT do not have a PCH so here also handling this case by unseting
RESET_PCH_HANDSHAKE_ENABLE.

v2(Rodrigo):
- renamed to intel_pch_reset_handshake()
- added comment about why BXT need the bit to be unset

v3(Rodrigo and Ville):
- added bool have_pch to intel_pch_reset_handshake()
- added back BXT comment

Subject: drm/i915: Unset reset pch handshake when PCH is not present in one
 place
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Right now RESET_PCH_HANDSHAKE_ENABLE is enabled all the times inside
of intel_power_domains_init_hw() and if PCH is NOP it is unsed in
i915_gem_init_hw().
So making skl_pch_reset_handshake() handle both cases and calling
it for the missing gens in intel_power_domains_init_hw().
Ivybridge have a different register and bits but with the same
objective so moving it too.

v2(Rodrigo):
- handling IVYBRIDGE case inside intel_pch_reset_handshake()

v4(Rodrigo and Ville):
- moving the enable/disable decision to callers

Subject: drm/i915: Do not modifiy reserved bit in gens that do not have IPC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

IPC was only added in SKL+(actually we don't even enable for SKL due
WA) so without this change, driver was writing to a reserved bit.

Also removing the uncessary dev_priv->ipc_enabled = false; as now
gens without IPC will not have IPC enabled.

v2(Rodrigo):
- moved the new handling of WA #0477 to the next patch

SKL has IPC but it should not be set according to the WA, so lets
just mark as it don't have it to simply the code and avoid
unnecessary MMIO writes at every call to intel_enable_ipc().

Subject: drm/i915/csr: keep max firmware size together with firmare name and
 version

Move max firmware size to the same if ladder with firmware name and
required version. This allows us to detect the missing max size for a
platform without actually loading the firmware, and makes the whole
thing easier to maintain.

We need to move the power get earlier to allow for early return in the
missing platform case. While at it, extend the comment on why we return
with the reference held on errors.

We also need to move the module parameter override later to reuse the
max firmware size, which is independent of the override.

v2: Add comment on why we leak the wakeref on errors (Chris)

v3: Rebase

With i915.dmc_firmware_path="" it's obvious the intention is to disable
CSR firmware loading. Bypass the firmware request altogether in this
case, with more obvious debug logging.

v2: Use DRM_INFO for logging (Chris)

Subject: drm/i915/selftests: Smoketest preemption
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Very light stress test to bombard the submission backends with a large
stream with requests of randomly assigned priorities. Preemption will be
occasionally requested, but unlikely to ever succeed! (Although we may
build a long queue of requests and so may trigger an attempt to inject a
preempt context, as we emit no batch, the arbitration window is limited
to between requests inside the ringbuffer. The likelihood of actually
causing a preemption event is therefore very small. A later variant
should try to improve the likelihood of preemption events!)

v2: Include a second pattern with more frequent preemption

Subject: drm/i915: Trim partial view sg lists

Partial views are small but there can be many of them, and since the sg
list space for them is allocated pessimistically, we can save some slab by
trimming the unused tail entries.

Subject: drm/i915: Remove i915.enable_ppgtt override

Now that we are confident in providing full-ppgtt where supported,
remove the ability to override the context isolation.

v2: Remove faked aliasing-ppgtt for testing as it no longer is accepted.
v3: s/USES/HAS/ to match usage and reject attempts to load the module on
old GVT-g setups that do not provide support for full-ppgtt.
v4: Insulate ABI ppGTT values from our internal enum (later plans
involve moving ppGTT depth out of the enum, thus potentially breaking
ABI unless we document the current values).

Subject: drm/i915: Check for panel orientation quirks on eDP panels

So far we have only been calling
drm_connector_init_panel_orientation_property(), which checks for
panel orientation quirks in the drm_panel_orientation_quirks.c file,
for DSI panels as so far only devices with DSI panels have had panels
which are not mounted up right.

The new GPD win2 device uses a portrait screen in a landscape case,
so now we've a device with an eDP panel which needs the panel-orientation
property to let the fbcon code and userspace know that the image needs to
be fixed-up.

This commit makes intel_edp_init_connector() call
drm_connector_init_panel_orientation_property() so that the property
gets added.

Subject: drm/i915/csr: restructure CSR firmware definition macros

Use uniform prefixes for firmware path, version and size. Unify
alignments. Order macro groups as in the if ladder using them. Add
platform specific max firmware size macros for all platforms for clarity
in the if ladder. Place the max firmware size macros in the platform
specific macro groups.

No functional changes.

Subject: drm/i915/execlists: Avoid kicking priority on the current context

If the request is currently on the HW (in port 0), then we do not need
to kick the submission tasklet to evaluate whether we should be
preempting itself in order to execute it again.

In the case that was annoying me:

   execlists_schedule: rq(18:211173).prio=0 -> 2
   need_preempt: last(18:211174).prio=0, queue.prio=2

We are bumping the priority of the first of a pair of requests running
in the current context. Then when evaluating preempt, we would see that
that our priority request is higher than the last executing request in
ELSP0 and so trigger preemption, not realising that our intended request
was already executing.

v2: As we assume state of the execlists->port[] that is only valid while
we hold the timeline lock we have to repeat some earlier tests that on
the validity of the node.
v3: Wrap guc submission under the timeline.lock as is now the way of all
things.

Subject: drm/i915/dp: Fix link retraining comment in intel_dp_long_pulse()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Comment claims link needs to be retrained because the connected sink raised
a long pulse to indicate link loss. If the sink did so,
intel_dp_hotplug() would have handled link retraining. Looking at the
logs in Bugzilla referenced in commit '3cf71bc9904d ("drm/i915: Re-apply
Perform link quality check, unconditionally during long pulse"")', the
issue is that the sink does not trigger an interrupt. What we want is
->detect() from user space to check link status and retrain. Ville's
review for the original patch also indicates the same root cause. So,
rewrite the comment.

v2: Patch split and rewrote comment.

Commit '3cf71bc9904d ("drm/i915: Re-apply "Perform link quality check,
unconditionally during long pulse"")' applies a work around for sinks
that don't signal link loss. The work around does not need to have to be
that broad as the issue was seen with only one particular monitor; limit
this only for external displays as eDP features like PSR turn off the link
and the driver ends up retraining the link seeeing that link is not
synchronized.

Subject: drm/i915/dp: Do not grab crtc modeset lock in intel_dp_detect()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A crtc modeset lock was added for link retraining but
intel_dp_retrain_link() knows to take the necessary locks since
commit c85d200e8321 ("drm/i915: Move SST DP link retraining into the
->post_hotplug() hook")
v2: Drop AUX power domain reference in the early return path

Subject: drm/i915/dp: optimize eDP 1.4+ link config fast and narrow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We've opted to use the maximum link rate and lane count for eDP panels,
because typically the maximum supported configuration reported by the
panel has matched the native resolution requirements of the panel, and
optimizing the link has lead to problems.

With eDP 1.4 rate select method and DSC features, this is decreasingly
the case. There's a need to optimize the link parameters. Moreover,
already eDP 1.3 states fast link with fewer lanes is preferred over the
wide and slow. (Wide and slow should still be more reliable for longer
cable lengths.)

Additionally, there have been reports of panels failing on arbitrary
link configurations, although arguably all configurations they claim to
support should work.

Optimize eDP 1.4+ link config fast and narrow.

Side note: The implementation has a near duplicate of the link config
function, with just the two inner for loops turned inside out. Perhaps
there'd be a way to make this, say, more table driven to reduce the
duplication, but seems like that would lead to duplication in the table
generation. We'll also have to see how the link config optimization for
DSC turns out.

Subject: drm/i915: Reserve some priority bits for internal use

In the next few patches, we will want to give a small priority boost to
some requests/queues but not so much that we perturb the user controlled
order. As such we will shift the user priority bits higher leaving
ourselves a few low priority bits for our internal bumping.

From 85f5e1f385b7643ee31e0530a1daa2438ac27aaf Mon Sep 17 00:00:00 2001

Subject: drm/i915: Combine multiple internal plists into the same
 i915_priolist bucket

As we are about to allow ourselves to slightly bump the user priority
into a few different sublevels, packthose internal priority lists
into the same i915_priolist to keep the rbtree compact and avoid having
to allocate the default user priority even after the internal bumping.
The downside to having an requests[] rather than a node per active list,
is that we then have to walk over the empty higher priority lists. To
compensate, we track the active buckets and use a small bitmap to skip
over any inactive ones.

v2: Use MASK of internal levels to simplify our usage.
v3: Prevent overflow when SHIFT is zero.

Subject: drm/i915: Priority boost for new clients

Taken from an idea used for FQ_CODEL, we give the first request of a
new request flows a small priority boost. These flows are likely to
correspond with short, interactive tasks and so be more latency sensitive
than the longer free running queues. As soon as the client has more than
one request in the queue, further requests are not boosted and it settles
down into ordinary steady state behaviour.  Such small kicks dramatically
help combat the starvation issue, by allowing each client the opportunity
to run even when the system is under heavy throughput load (within the
constraints of the user selected priority).

v2: Mark the preempted request as the start of a new flow, to prevent a
single client being continually gazumped by its peers.

Subject: drm/i915: Pull scheduling under standalone lock

Currently, the backend scheduling code abuses struct_mutex into order to
have a global lock to manipulate a temporary list (without widespread
allocation) and to protect against list modifications. This is an
extraneous coupling to struct_mutex and further can not extend beyond
the local device.

Pull all the code that needs to be under the one true lock into
i915_scheduler.c, and make it so.

Subject: drm/i915: Priority boost for waiting clients

Latency is in the eye of the beholder. In the case where a client stops
and waits for the gpu, give that request chain a small priority boost
(not so that it overtakes higher priority clients, to preserve the
external ordering) so that ideally the wait completes earlier.

v2: Tvrtko recommends to keep the boost-from-user-stall as small as
possible and to allow new client flows to be preferred for interactivity
over stalls.

Subject: drm/i915: Add plane alpha blending support, v2.

Add plane alpha blending support with the different blend modes.
This has been tested on a icl to show the correct results,
on earlier platforms small rounding errors cause issues. But this
already happens case with fully transparant or fully opaque RGB8888
fb's.

The recommended HW workaround is to disable alpha blending when the
plane alpha is 0 (transparant, hide plane) or 0xff (opaque, disable blending).
This is easy to implement on any platform, so just do that.

The tests for userspace are also available, and pass on gen11.

Changes since v1:
- Change mistaken < 0xff0 to 0xff00.
- Only set PLANE_KEYMSK_ALPHA_ENABLE when plane alpha < 0xff00, ignore blend mode.
- Rework disabling FBC when per pixel alpha is used.

A few callsites were deciding on using WC or WB maps based on
HAS_LLC(), so replace them with the equivalent helper function
i915_coherent_map_type().

Subject: drm/i915: Show actual alongside requested frequency in
 debugfs/i915_rps_boost_info

Previously we hesitated in adding the hw probe for the actual GPU
frequency for rps_boost as it is quite cumbersome, but given some
surprising HW behaviour it would be useful to know both the RPS boost
state and the actual HW state in one location.

v2: vlv/chv needs more tlc

Subject: drm/i915: fix wrong error number report

During driver load it's considered that the i915_driver_create()
function fails only in case of insufficient memory. Indeed, in
case of failure of i915_driver_create(), the load function
returns indiscriminately -ENOMEM ignoring the real cause of
failure.

In i915_driver_create() get the consistent error value from
drm_dev_init() and embed it in the pointer return value.

Subject: drm/i915: Handle incomplete Z_FINISH for compressed error states

The final call to zlib_deflate(Z_FINISH) may require more output
space to be allocated and so needs to re-invoked. Failure to do so in
the current code leads to incomplete zlib streams (albeit intact due to
the use of Z_SYNC_FLUSH) resulting in the occasional short object
capture.

v2: Check against overrunning our pre-allocated page array
v3: Drop Z_SYNC_FLUSH entirely

Testcase: igt/i915-error-capture.js

Subject: drm/i915: Clear the error PTE just once on finish

We do not need to continually clear our dedicated PTE for error capture
as it will be updated and invalidated to the next object. Only at the
end do we wish to be sure that the PTE doesn't point back to any buffer.

Subject: drm/i915/execlists: Flush the CS events before unpinning

Inside the execlists submission tasklet, we often make the mistake of
assuming that everything beneath the request is available for use.
However, the submission and the request live on two separate timelines,
and the request contents may be freed from an early retirement before we
have had a chance to run the submission tasklet (think ksoftirqd). To
safeguard ourselves against any mistakes, flush the tasklet before we
unpin the context if execlists still has a reference to this context.

v2: Pull hw_context->active tracking into schedule_in and schedule_out.

Subject: drm/i915/guc: init GuC descriptors after GuC load

GuC stores some data in there, which might be stale after a reset.
We already reset the WQ head and tail, but more things are being moved
to the descriptor with the interface updates. Instead of trying to track
them one by one, always memset and init the descriptors from scratch
after GuC is loaded.
The code is also reorganized so that the above operations and the
doorbell creation are grouped as "client enabling"

v2: add proc_desc_fini for symmetry (Daniele), remove unneeded var init,
add guc_is_alive() (Michal)

Subject: drm/i915/guc: Don't clear the cookie on doorbell destroy

If the HW has not processed the db invalidation request yet, clearing
the cookie can generate a db ring. We clear the cookie when we
(re-)allocate the doorbell so no need to do it on destroy as well as no
one is going to look at it while the doorbell is inactive

Subject: drm/i915: Provide more clues as to why MST is/is not used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Always print out the information whether the port and sink can each
do MST. And let's include the modparam in the debug output as well.
Makes life a little less confusing when you don't have to wonder
why MST isn't kicking in.

This does cause a slight change in our behaviour towards the sink.
Previously we only read the MSTM_CAP register after passing all
the other checks. Now we will read that register regardless. Hopefully
some crazy sink doesn't get confused by a simple register read.

Subject: drm/i915: Use the correct crtc when sanitizing plane mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When we decide that a plane is attached to the wrong pipe we try
to turn off said plane. However we are passing around the crtc we
think that the plane is supposed to be using rather than the crtc
it is currently using. That doesn't work all that well because
we may have to do vblank waits etc. and the other pipe might
not even be enabled here. So let's pass the plane's current crtc to
intel_plane_disable_noatomic() so that it can its job correctly.

To do that semi-cleanly we also have to change the plane readout
to record the plane's visibility into the bitmasks of the crtc
where the plane is currently enabled rather than to the crtc
we want to use for the plane.

One caveat here is that our active_planes bitmask will get confused
if both planes are enabled on the same pipe. Fortunately we can use
plane_mask to reconstruct active_planes sufficiently since
plane_mask still has the same meaning (is the plane visible?)
during readout. We also have to do the same during the initial
plane readout as the second plane could clear the active_planes
bit the first plane had already set.

v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel)
    Add Daniel's proposed comment to better document why we do this
    Drop the redundant intel_set_plane_visible() call

Subject: drm/i915: Only reset seqno if actually idle

Before we can reset the seqno, we have to be sure the engines are idle.
In debugfs/i915_drop_caches_set, we do wait_for_idle but allow ourselves
to be interrupted. We should only proceed to reset the seqno then if we
were not interrupted, and so also avoid overwriting the error status.

Subject: drm/i915: Remove the global cache shrink & rcu barrier on allocation
 failure

Earlier, we reasoned that having idled the gpu under mempressure, that
would be a good time to trim our request slabs in order to perform the
next request allocation. We have stopped performing the global operation
on the device (no idling) and wish to make the allocation failure
handling more local, so out with the global barrier that may take a long
time.

Subject: drm/i915: Make panel fitter functions take state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If we look at the correct state instead of crtc->config, we can nuke the
force parameter, and we cleanup a few more users of crtc->config at the
same time.

Instead of passing crtc and dereferencing crtc->config,
passs the correct crtc_state and obtain the crtc pointer from there.

Changes since v1:
- Move vlv/chv changes and i9xx_set_pll_dividers changes
  from crtc_enable/disable patches to here.
- Add commit message.

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

Do not rely on crtc->config any more. Remove the assertion from
ibx_pch_dpll_disable, because we the dpll state tracking should
already handle this case correctly.

Changes since v1:
- Fixup accidental early return in intel_prepare_shared_dpll, oops!
Changes since v2:
- Don't use the freed crtc_state in intel_crtc_disable_noatomic()

Instead of passing crtc and dereferencing crtc->config,
pass the correct crtc_state and obtain the crtc pointer from there.

MIME-Version: 1.0

fbdev init shouldn't race with userspace since it's called from
intel_modeset_init, so it's safe to dereference crtc->state and
assume nothing changed yet.

At least not more harmful than crtc->config.

Subject: drm/i915: Fix ILK-IVB sprite enable delays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sprite enable on ILK-IVB may take two frames to complete
when the hardware is in big FIFO mode (LP1+). That is
not entirely great as it means the sprite enable may
actually happen one frame after we've already signalled
flip completion. At the very least crc checks may fail
due to the sprite not yet being visible when we expect it.

We already have code to deal with big FIFO mode when it
comes to the sprite scaling on IVB
(WaCxSRDisabledForSpriteScaling:ivb). Let's extend that
workaround to kick in whenever the sprite is in the process
of being enabled. Also ILK/SNB bspec has some notes to
indicate that we should most likely also do the sprite
scaling w/a on all three platforms, so let's do that as well.

Pretty easy to reproduce on SNB/IVB. ILK has proved more
elusive, but let's trust the spec and include it as well.

v2: Make sure the pipe is active before the vblank wait

Subject: drm/i915: Apply correct ddi translation table for AML device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Amber Lake used the same gen graphics as Kaby Lake. Kernel driver
should configure KBL's DDI buffer setting for AML ULX as well.

So far, driver would load DDI translation table that used for
KBL H/S platform and apply it on AML devices. But AML is belong to
ULX series. This change will lead driver to apply KBL-Y's DDI table
for AML devices to avoid unexpected eDP/DP signal quality issue.

Subject: drm/i915/icl: MBUS B credit change

No functional change. But just a minor change to keep
up with Spec, since it has changed since commit c3cc39c539d4
("drm/i915/icl: program mbus during pipe enable")

The instructions previously said to program pipe's
B credit = 24 / number of pipes, which is 8 for ICL.
Now the spec gives us direct values independent of number
of pipes. Let's keep in sync.

Also just a reorder on fields to make easier to compare
against spec's sequence: A -> BW -> B.

Subject: drm/i915: Populate possible_crtcs for primary/cursor planes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We're currently not providing the possible_crtcs mask to
drm_universal_plane_init() for primary/cursor planes. While that does
work on account of drm_crtc_init_with_planes() filling those up
for us, it's inconsisten with what we're doing for sprite planes.

Let's just always pass the possible_crtcs bitmask to
drm_universal_plane_init(). This does assume that crtc->index
== pipe. But we're already making that assumption elsewhere so
it doesn't seem like a very big sin here.

MIME-Version: 1.0

All CNL universal planes support horizontal mirroring. Currently
we expose the capability only for the primary plane. Expose it
for the overlay planes as well.

Subject: drm/i915: Disallow plane scaling with specific pixel formats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Plane scaling is not supported with specific pixel formats. Disallow
plane scaling when such a format is used. Currently the only such
pixel format we expose is C8, but in case we add more in the future
let's make it easy to deal with them.

v2: Redo due to plane_check() refactoring

All SKL+ universal planes support the same set of formats (with the

for primary and sprites the same.

And make the format list const while at it.

v2: Deal with the "planar" format list as well

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

No point in having each caller of intel_create_plane_state() initialize
the scaler_id to -1. Instead just do it in intel_create_plane_state().

Previously we left scaler_id at 0 for pre-SKL platforms, but I can't
see how initializing it to -1 always would cause any harm.

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

There's not much point in following the primary vs. sprite split
for the SKL+ universal plane init code. The only difference is
of our own doing in the form of the .check_plane(). Let's make
a small exception for that little detail and otherwise share
the same code to initialize all the universal planes.

Eventually we should eliminate the mess around .check_plane()
as well, but for now let's be happy with some code reduction.

v2: Remember to set up plane->has_fbc
    Make skl_plane_has_ccs() static
v3: Rebase due to NV12, rename some variables
v4: Don't leave the color_encoding/range props behind
v5: Rebase dur to blend properties, skl_plane_max_stride() and
    skl_plane_check()
v6: Make skl_update_plane() static

Use a more familiar naming pattern for our variables in the sprite plane
init function.

v2: Drop the redundant 'plane' from plane_formats and num_planes_formats
    too
v3: Rebase due to ->max_stride() and ->check_plane() changes

Incorrect TDL's SSP address shift in SARB for 16:6 & 18:8 modes.
Disable the Sampler state prefetch functionality in the SARB by
programming 0xB000[30] to '1'. This is to be done at boot time
and the feature must remain disabled permanently.

Fixes flaky tex-mip-level-selection* piglit tests with Mesa i965
driver.

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

Currently we destroy the backlight during connector unregistration.
That means the final modeset performed by drm_atomic_helper_shutdown()
will leave the backlight on. We don't want that so let's just move
intel_panel_destroy_backlight() into intel_panel_fini() which gets
called during connector destuction.

We still unregister the user visible backlight device during connector
unregistration.

As long as the connector was zeroed during allocation calling
intel_panel_fini() is safe even if we haven't initialized

check from dp connector destruction.

Subject: drm/atomic_helper: Disallow new modesets on unregistered connectors

With the exception of modesets which would switch the DPMS state of a
connector from on to off, we want to make sure that we disallow all
modesets which would result in enabling a new monitor or a new mode
configuration on a monitor if the connector for the display in question
is no longer registered. This allows us to stop userspace from trying to
enable new displays on connectors for an MST topology that were just
removed from the system, without preventing userspace from disabling
DPMS on those connectors.

Changes since v5:
- Fix typo in comment, nothing else

Subject: drm/i915: Don't unset intel_connector->mst_port

Currently we set intel_connector->mst_port to NULL to signify that the
MST port has been removed from the system so that we can prevent further
action on the port such as connector probes, mode probing, etc.
However, we're going to need access to intel_connector->mst_port in
order to fixup ->best_encoder() so that it can always return the correct
encoder for an MST port to prevent legacy DPMS prop changes from
failing. This should be safe, so instead keep intel_connector->mst_port
always set and instead just check the status of
drm_connector->regustered to signify whether or not the connector has
disappeared from the system.

Changes since v2:
- Add a comment to mst_port_gone (Jani Nikula)
- Change mst_port_gone to a u8 instead of a bool, per the kernel bot.
  Apparently bool is discouraged in structs these days
Changes since v4:
- Don't use mst_port_gone at all! Just check if the connector is
  registered or not - Daniel Vetter

Subject: drm/i915: Skip vcpi allocation for MSTB ports that are gone

Since we need to be able to allow DPMS on->off prop changes after an MST
port has disappeared from the system, we need to be able to make sure we
can compute a config for the resulting atomic commit. Currently this is
impossible when the port has disappeared, since the VCPI slot searching
we try to do in intel_dp_mst_compute_config() will fail with -EINVAL.

Since the only commits we want to allow on no-longer-present MST ports
are ones that shut off display hardware, we already know that no VCPI
allocations are needed. So, hardcode the VCPI slot count to 0 when
intel_dp_mst_compute_config() is called on an MST port that's gone.

Changes since V4:
- Don't use mst_port_gone at all, just check whether or not the drm
  connector is registered - Daniel Vetter

Subject: drm/i915: Fix intel_dp_mst_best_encoder()

Currently, i915 appears to rely on blocking modesets on
no-longer-present MSTB ports by simply returning NULL for
->best_encoder(), which in turn causes any new atomic commits that don't
disable the CRTC to fail. This is wrong however, since we still want to
allow userspace to disable CRTCs on no-longer-present MSTB ports by
changing the DPMS state to off and this still requires that we retrieve
an encoder.

So, fix this by always returning a valid encoder regardless of the state
of the MST port.

Changes since v1:
- Remove mst atomic helper, since this got replaced with a much simpler
  solution

Subject: drm/i915: add a common connector type independent destroy hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Almost all of the connector destroy functions do the same thing. The
differences are in the edid, detect_edid and panel cleanups, but those
are safely NULL when not initialized. Roll out a common connector
destroy hook.

Inspired by commit bc3213c44415 ("drm/i915: Drop the eDP check from
intel_dp_connector_destroy()").

Subject: drm/i915/dp: Link train Fallback on eDP only if fallback link BW can
 fit panel's native mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes the original commit c0cfb10d9e1de49 ("drm/i915/edp:
Do not do link training fallback or prune modes on EDP") that causes
a blank screen in case of certain eDP panels (Eg: seen on Dell XPS13 9350)
where first link training fails and a retraining is required by falling
back to lower link rate/lane count.
In case of some panels they advertise higher link rate/lane count
than whats required for supporting the panel's native mode.
But we always link train at highest link rate/lane count for eDP
and if that fails we can still fallback to lower link rate/lane count
as long as the fallback link BW still fits the native mode to avoid
pruning the panel's native mode yet retraining at fallback values
to recover from a blank screen.

v3:
* Add const for fixed_mode (Ville)
v2:
* Send uevent if link failure on eDP unconditionally

Subject: drm/i915: Show the DPCD read error inline

When reporting the DPCD dump through debugfs, show the errors inline
where appropriate. If a read at one particular offset fails, report it.

Subject: drm/i915: nuke the intel_lvds_connector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For a while we carried lvds connector specific data in the lvds
connector, but since commit 05c72e77ccda ("drm/i915: Nuke the LVDS lid
notifier") we haven't needed it. Revert back to plain intel_connector.

Subject: drm/i915: rename intel_modes.c to intel_connector.c
MIME-Version: 1.0

The common denominator here seems to be connector more than
modes. Prepare for moving more connector functions to the same place. No
functional changes.

Subject: drm/i915: move intel connector specific functions to
 intel_connector.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we have intel_connector.c, move the connector specific
functions from intel_display.c there. Fix a few checkpatch complaints
while at it. No functional changes.

It appears when testing my previous fix for some of the legacy

started appearing on my machine after a rebase as being from upstream.
But it appears they actually came from my patch series:

[    2.980884] ---[ end trace 5eb47a76277d4731 ]---

The cause of this appears to be due to the fact that if there's
pre-existing display state that was set by the BIOS when i915 loads, it
will attempt to perform a modeset before the driver is registered with
userspace. Since this happens before the driver's registered with
userspace, it's connectors are also unregistered and thus-states which
would turn on DPMS on a connector end up getting rejected since the
connector isn't registered.

These bugs managed to get past Intel's CI partially due to the fact it
never ran a full test on my patches for some reason, but also because
all of the tests unload the GPU once before running. Since this bug is
only really triggered when the drivers tries to perform a modeset before
it's been fully registered with userspace when coming from whatever
display configuration the firmware left us with, it likely would never
have been picked up by CI in the first place.

After some discussion with vsyrjala, we decided the best course of
action would be to just move the unregistered connector checks out of
update_connector_routing() and into drm_atomic_set_crtc_for_connector().
The reason for this being that legacy modesetting isn't going to be
expecting failures anywhere (at least this is the case with X), so
ideally we want to ensure that any DPMS changes will still work even on
unregistered connectors. Instead, we now only reject new modesets which
would change the current CRTC assigned to an unregistered connector
unless no new CRTC is being assigned to replace the connector's previous
one.

Subject: drm/nouveau: Fix nv50_mstc->best_encoder()

As mentioned in the previous commit, we currently prevent new modesets
on recently-removed MST connectors by returning no encoder from our
->best_encoder() callback once the MST port has disappeared. This is
wrong however, because it prevents legacy modesetting users from being
able to disable CRTCs on MST connectors after the connector's respective
topology has disappeared.

So, fix this by instead by just always returning a valid encoder.

Changes since v2:
- Remove usage of atomic MST helper for now, since that got replaced
  with a much simpler solution

Subject: drm/i915/selftests: Disable shrinker across mmap-exhaustion

For mmap-exhaustion, we deliberately put the system under a large amount
of pressure to ensure that we are able to reap mmap-offsets from dead
objects. If background activity does that reaping for us, that defeats
the purpose of the test and in some cases will fail our sanity checks
(because of the fake activity we use to prevent the idle worker).

Subject: drm/i915: DRM_FORMAT_C8 is not possible with Yf tiling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Function intel_framebuffer_init() checks for the possibilities during
framebuffer creation (addfb ioctl time). It is missing the fact that
the indexed format is not supported with Yf tiling.

It is worth noticing that skl_plane_format_mod_supported() correctly
handles for the C8/Yf combination, but this function runs during
modeset time, so we only reject the combination later.

Ville recently proposed a new IGT test that only uses addfb to assert
supported formats, so that IGT was failing. Add the check so we get
green squares right from the start after Ville merges his test.

Also drive-by fix the missing /* fall through */ in the chunk we
modified by just turning it into a "break;" since IMHO breaks are
easier to read than fall-throughs.

Subject: drm/i915: fix the transition minimums for gen9+ watermarks

The transition minimum is 14 blocks for gens 9 and 10, and 4 blocks
for gen 11. This minimum value is supposed to be added to the
configurable trans_amount. This matches both BSpec and additional
information provided by our HW engineers.

Subject: drm/i915: transition WMs ask for Selected Result Blocks

The transition watermarks ask for Selected Result Blocks (the real
value), not Result Blocks (the integer value). Given how ceilings are
applied in both the non-transition and the transition watermarks
calculations, we can get away with assuming that Selected Result
Blocks is actually Result Blocks minus 1 without any rounding errors.

Subject: drm/i915: don't write PLANE_BUF_CFG twice every time

We were writing to PLANE_BUF_CFG(pipe, plane_id) twice for every
platform, and we were even using different values on the gen10- planar
case. The first write is useless since it just gets replaced with the
next one, so kill it.

There's a lot to improve in the DDB code, but let's start by avoiding
the double write.

This message is currently marked as DRM_DEBUG_ATOMIC. I would like it
to be DRM_DEBUG_KMS since it is more KMS than atomic, and this will
also make the message appear in the CI logs, which may or may not help
us with some FIFO underrun bugs.

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

This patch adds an enum "intel_output_format" to represent
the output format of a particular CRTC. This enum will be
used to produce a RGB/YCBCR4:4:4/YCBCR4:2:0 output format
during the atomic modeset calculations.

V5:
- Created this separate patch to introduce and init output_format.
- Initialize parameters of output_format_str respectively (Jani N).
- Call it intel_output_format than crtc_output_format(Ville).
- Set output format in pipe_config for every encoder (Ville).
- Get rid of extra DRM_DEBUG_KMS during get_pipe_config (Ville)

V6: Rebase
V7: Fixed alignment warnings (checkpatch)
V8: Another check[atch warning for alignment
V9: Rebase
V10: Rebase on top of DSI restructure
V11: Addressed review comment from Ville
	- Set CRTC format for pre-HSW get_pipe_config() function too.
     Added Ville's R-B

From 33b7f3ee6e008311876cef3f3629c3affa9ed66c Mon Sep 17 00:00:00 2001
From: Shashank Sharma <shashank.sharma@intel.com>

Subject: drm/i915: Add CRTC output format YCBCR 4:2:0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, we are using a bool in CRTC state (state->ycbcr420),
to indicate modeset, that the output format is YCBCR 4:2:0. Now in
order to support other YCBCR formats, we will need more such flags.

This patch adds a new enum parameter for YCBCR 4:2:0 outputs, in the
CRTC output formats and then plugs it during the modeset.

V3: Added this patch in the series, to address review comments from
    second patchset.
V4: Added r-b from Maarten (on v3)
    Addressed review comments from Ville:
        - Change the enum name to intel_output_format.
        - Start the enum value (INVALID) from 0 instaed of 1.
        - Set the crtc's output_format to RGB in encoder's compute_config.
V5: Broke previous patch 1 into two parts,
    - first patch to add CRTC output format in general
    - second patch (this one) to add YCBCR 4:2:0 output
      format specifically.
    - Use ARRAY_SIZE(format_str) for output format validity check (Ville)
V6: Added a separate function to calculate crtc_state->output_format, and
    calling it from various get_config function (Fix CI build warning)
V7: Fixed checkpatch warnings for alignment
V8: Rebase
V9: Rebase
V10: Rebase
V11: Addressed review comments from Ville:
	- Change check for CRTC output format from > ARRAY_SIZE to >= ARRAY_SIZE.
	- Check for values < INTEL_OUTPUT_FORMAT_RGB is unnecessary.
	- No need to get CRTC YCBCR config, for pre-BDW functions.
    Added Ville's r-b.

Subject: drm/i915: Add CRTC output format YCBCR 4:4:4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds support for YCBCR 4:4:4 CRTC output format.
To do this, this patch extends the existing YCBCR 4:2:0
framework by:
- Adding new parameter in for YCBCR 4:4:4 enum crtc_iutput_format.
- Adding case for YCBCR 4:4:4 in while setting AVI infoframes.
- Adding necessary checks in modeset sequence.

Subject: drm/i915: Check LSPCON vendor OUI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Intel LSPCON chip is provided by 2 vendors:
- Megachips America (MCA)
- Parade technologies (Parade tech)

Its important to know the vendor of this chip, as the address to
write AVI infoframes is different for those two.

This patch reads the vendor OUI signature, and marks into LSPCON
encoder structure for future usages.

This patch also does a small re-arrangement of the code, by moving
lspcon mode change into probe function.

V2: Use dp->desc for OUI detection, dont add a helper for this

Subject: drm/i915: Add AVI infoframe support for LSPCON

In order to pass AVI infoframes to LSPCON devices, a source has to
write them in a vendor recommended method and location.

This patch series:
- adds generic LSPCON infoframe setup functions.
- registers these functions into existing AVI infoframe framework.
- triggers these functions from modeset sequence.

Next patches in the series will add vendor specific code.

V2: Added new parameter to align with new definition of
    drm_hdmi_avi_infoframe_quant_range
V3: Added r-b from Maarten (for V2)
    Added new parameter output_format in struct lspcon to accommodate
    Ville's review comments on last patch of the series
V4: Addressed Ville's review comment
    - Do not add output_format in LSPCON state, as its non-atomic. Add
      this into CRTC state (added in a later patch).
V5: Rebase
V6: Rebase
V7: Rebase
V8: Rebase
V9: Rebase
V10: Rebase
V11: Accommodated rebasing changes in intel_git_port fptrs (set_infoframes and infoframe_enabled)

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

LSPCON is a DP branch device, so LSPCON vendors define
specific methods to pass AVI infoframes to the the chip.
This patch adds:
- a generic wrapper function for writing AVI infoframes for
  all LSPCON devices.
- a vendor specific function to wrire AVI infoframes into
  MCA LSPCON devices.

Subject: drm/i915: Add YCBCR 4:2:0/4:4:4 support for LSPCON

LSPCON chips can generate YCBCR outputs, if asked nicely :).

In order to generate YCBCR 4:2:0 outputs, a source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:2:0 in AVI infoframes

Whereas for YCBCR 4:4:4 outputs, the source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:4:4 in AVI infoframes

So for both 4:2:0 as well as 4:4:4 outputs, we are driving the
pipe for YCBCR 4:4:4 output, but AVI infoframe's color space
information indicates LSPCON FW to start scaling down from YCBCR
4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by
LSPCON device, we need not to reserve a scaler for 4:2:0 outputs.

V2: rebase
V3: Addressed review comments from Ville
    - add enum crtc_output_format instead of bool ycbcr420
    - use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output
      cases in this way we will have YCBCR 4:4:4 framework ready (except
      the ABI part)
V4: Added r-b from Maarten (for v3)
    Addressed review comments from Ville:
    - Do not add a non-atomic state variable to determine lspcon output.
      Instead add bool in CRTC state to indicate lspcon based scaling.
V5: Addressed review comments from Ville:
    - Change the state bool name from external scaling to something more
      relavent.
    - Keep the info and adjusted_mode structures const.
    - use crtc_state instead of pipe_config.
    - Push all the config change into lspcon_ycbcr420_config function.
V6: Rebase, small changes to accommodate changes in patch 2.
V7: Fixed checkpatch warnings for alignment
V8: Rebase

    PS: Ignored following warnings to match the current formatting:

Disable master interrupt before reading level indications.
This will close a race where we get a level indication between
reading and disabling, generating an extra interrupt where we
could have avoided one.

Further, as the reading acts also as a post, replace the
write/post on the irq reset with the helper. On enabling side,
posting doesn't serve any purpose so it can also be replaced
with helper.

All other master control register bits, except the enable,
are read only and they are level indications of the second
level interrupt status. Only touch enable bit and rectify

Subject: drm/i915: Always read out M2_N2 in intel_cpu_transcoder_get_m_n, v2.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

has_drrs is a flag we can't read out. We set it when seamless DRRS is
enabled in pipe_config, so intel_dump_pipe_config() and
intel_pipe_config_compare() will continue to do the right thing when
has_drrs is set on the real state.

This removes one more dereference of crtc->config.
While at it, fixup the comment and also read out M2_N2 for CHV, since
we program it in the set_m_n function.

Changes since v1:
- Only read out M2/N2 on platforms that support DRRS.

We have to look at crtc_state, so pass that instead.
Also cleanup the use of dev vs dev_priv, we really want to pass along
dev_priv.

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

Display WA #1178 is meant to fix Aux channel voltage swing too low with
some type C dongles. It applies to external ports on combo phy. On
Icelake this is port A and B when those are not eDP.

v2: follow the spec to the letter: include Aux A and just check if it's
    not eDP instead of checking only for Aux B.

This patch creates a function/wrapper to check if port is combophy port
instead of explicitly comparing ports.

Changes since V1:
 - keep all intel_port_is_* helper together (Lucas)

Subject: drm/i915/icl: Combine all port/combophy macros at one place

This patch combines CNL/ICL specific port/combophy macros together
at one location. This is prework for patches later in series where
new macros to find port/combophy register will be introduced.

v2: remove wrong empty line

From 4e53840fdfdd054f645a03fa27f79296fa0d5d15 Mon Sep 17 00:00:00 2001
From: Lucas De Marchi <lucas.demarchi@intel.com>
Date: Mon, 15 Oct 2018 19:35:17 -0700
Subject: drm/i915/icl: Introduce new macros to get combophy registers

combo-phy register instances are at same offset from base for each
combo-phy port, i.e.

Port A base offset: 0x16200
Port B base offset: 0x6C000

All the other addresses for both ports can be derived by calculating
offset to these base addresses.

PORT_CL_DW_OFFSET	0x0
PORT_CL_DW<x>		0 + x * 4

PORT_COMP_OFFSET	0x100
PORT_COMP_DW<x>		0x100 + x * 4

PORT_PCS_AUX_OFFSET     0x300
PORT_PCS_GRP_OFFSET     0x600
PORT_PCS_LN<y>_OFFSET   0x800 + y * 0x100

PORT_TX_AUX_OFFSET      0x380
PORT_TX_GRP_OFFSET      0x680
PORT_TX_LN<y>_OFFSET    0x880 + y * 0x100

And inside each PORT_TX_[AUX|GRP|LN] we add `dw * 4`.

Based on original patch by Mahesh Kumar <mahesh1.kumar@intel.com>.

v2: make port, dw and ln arguments follow the order in
    register's name

Subject: drm/i915: Ensure _print_param() builds with Clang

When building the kernel with Clang with defconfig and CONFIG_64BIT
disabled, vmlinux fails to link because of the BUILD_BUG in
_print_param.

ld: drivers/gpu/drm/i915/i915_params.o: in function `i915_params_dump':
i915_params.c:(.text+0x56): undefined reference to
`__compiletime_assert_191'

This function is semantically invalid unless the code is first inlined
then constant folded, which doesn't work for Clang because semantic
analysis happens before optimization/inlining.

[The above written by Nathan Chancellor <natechancellor@gmail.com>]

Use WARN_ONCE() instead of BUILD_BUG() to avoid the problem. The
WARN_ONCE() should get optimized away unless there's a type that's not
handled by _print_param().

Subject: drm/i915: Ensure intel_engine_init_execlist() builds with Clang

Clang build with UBSAN enabled leads to the following build error:

drivers/gpu/drm/i915/intel_engine_cs.o: In function `intel_engine_init_execlist':
drivers/gpu/drm/i915/intel_engine_cs.c:411: undefined reference to `__compiletime_assert_411'

Again, for this to work the code would first need to be inlined and then
constant folded, which doesn't work for Clang because semantic analysis
happens before optimization/inlining.

Use GEM_BUG_ON() instead of BUILD_BUG_ON().

v2: Use is_power_of_2() from log2.h (Chris)

Subject: drm/i915/guc: Fix Gen9 GuC loading workarounds

In commit 4502e9ec820d ("drm/i915/uc: Unify firmware loading") we
stopped converting errors detected during firmware transfer into
-EAGAIN and this indirectly killed our workarounds for Gen9 GuC.
Reactivate those workarounds by looking for actual -ETIMEDOUT error.

Subject: drm/i915/gen9+: Fix initial readout for Y tiled framebuffers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If BIOS configured a Y tiled FB we failed to set up the backing object
tiling accordingly, leading to a lack of GT fence installed and a
garbled console.

The problem was bisected to
commit 011f22eb545a ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2")
but it just revealed a pre-existing issue.

Kudos to Ville who suspected a missing fence looking at the corruption
on the screen.

Subject: drm/i915: Remove crtc->config dereference from drrs_ctl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Wait for idle, and iterate over connectors instead of encoders.
With this information we know crtc->state is the actual state,
and we can enable/disable drrs safely.

Subject: drm/i915/guc: fix GuC suspend/resume

The ENTER/EXIT_S_STATE actions queue the save/restore operation in GuC
FW and then return, so waiting on the H2G is not enough to guarantee
GuC is done.
When all the processing is done, GuC writes 0 to scratch register 14,
so we can poll on that. Note that GuC does not ensure that the value
in the register is different from 0 while the action is in progress
so we need to take care of that ourselves as well.

v2: improve comment, return early on GuC error and improve error

Subject: drm/atomic_helper: Stop modesets on unregistered connectors harder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unfortunately, it appears our fix in:
commit b5d29843d8ef ("drm/atomic_helper: Allow DPMS On<->Off changes
for unregistered connectors")

Which attempted to work around the problems introduced by:
commit 4d80273976bf ("drm/atomic_helper: Disallow new modesets on
unregistered connectors")

Is still not the right solution, as modesets can still be triggered
outside of drm_atomic_set_crtc_for_connector().

So in order to fix this, while still being careful that we don't break
modesets that a driver may perform before being registered with
userspace, we replace connector->registered with a tristate member,
connector->registration_state. This allows us to keep track of whether
or not a connector is still initializing and hasn't been exposed to
userspace, is currently registered and exposed to userspace, or has been
legitimately removed from the system after having once been present.

Using this info, we can prevent userspace from performing new modesets
on unregistered connectors while still allowing the driver to perform
modesets on unregistered connectors before the driver has finished being
registered.

Changes since v1:
- Fix WARN_ON() in drm_connector_cleanup() that CI caught with this
  patchset in igt@drv_module_reload@basic-reload-inject and
  igt@drv_module_reload@basic-reload by checking if the connector is
  registered instead of unregistered, as calling drm_connector_cleanup()
  on a connector that hasn't been registered with userspace yet should
  stay valid.
- Remove unregistered_connector_check(), and just go back to what we
  were doing before in commit 4d80273976bf ("drm/atomic_helper: Disallow
  new modesets on unregistered connectors") except replacing
  READ_ONCE(connector->registered) with drm_connector_is_unregistered().
  This gets rid of the behavior of allowing DPMS On<->Off, but that should
  be fine as it's more consistent with the UAPI we had before - danvet
- s/drm_connector_unregistered/drm_connector_is_unregistered/ - danvet
- Update documentation, fix some typos.

Subject: drm/i915: GEM_WARN_ON considered harmful

GEM_WARN_ON currently has dangerous semantics where it is completely
compiled out on !GEM_DEBUG builds. This can leave users who expect it to
be more like a WARN_ON, just without a warning in non-debug builds, in
complete ignorance.

Another gotcha with it is that it cannot be used as a statement. Which is
again different from a standard kernel WARN_ON.

This patch fixes both problems by making it behave as one would expect.

It can now be used both as an expression and as statement, and also the
condition evaluates properly in all builds - code under the conditional
will therefore not unexpectedly disappear.

To satisfy call sites which really want the code under the conditional to
completely disappear, we add GEM_DEBUG_WARN_ON and convert some of the
callers to it. This one can also be used as both expression and statement.

>From the above it follows GEM_DEBUG_WARN_ON should be used in situations
where we are certain the condition will be hit during development, but at
a place in code where error can be handled to the benefit of not crashing
the machine.

GEM_WARN_ON on the other hand should be used where condition may happen in
production and we just want to distinguish the level of debugging output
emitted between the production and debug build.

v2:
 * Dropped BUG_ON hunk.

Subject: drm/i915/huc: Normalize HuC status returned by I915_PARAM_HAS_HUC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In response for I915_PARAM_HAS_HUC we are returning value that
indicates if HuC firmware was loaded and verified. However, our
previously used positive value was based on specific register bit
which is about to change on future platform. Let's normalize our
return values to 0 and 1 before clients will start to use Gen9 value.

v2: use bool for implicit conversion (Chris)

Subject: drm/i915: make encoder enable and disable hooks optional

Encoders are not alike, make enable and disable hooks optional like
other hooks. Utilize this in DSI code, and remove the silly nop hook.

v2: Add the check also to intel_sanitize_encoder() (Madhav)

Subject: drm/i915/dsi: abstract dphy parameter init

intel_dsi_vbt_init() has grown too unwieldy, and it's about to be
modified due to ICL DSI. Abstract out the VLV specific dphy param
init. No functional changes. Intentionally no stylistic changes during
code movement.

Subject: drm/i915/guc: drop negative doorbell alloc selftest

The test requires driver tweaks to avoid causing error messages
on intentionally-triggered errors and to stop accessing non
existing register. However, this is a pure GuC FW interface test
and should be covered by FW validation, so it isn't really worth
tweaking the driver for it and we're better off dropping it instead.

Testing the driver running out of doorbells is already covered by
igt_guc_doorbells

Subject: drm/i915: Use i915_gem_object_get_dma_address() to populate rotated
 vmas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the kvmalloc_array() with i915_gem_object_get_dma_address() when
populating rotated vmas. One random access mechanism ought to be enough
for everyone?

To calculate the size of the radix tree I think we can do
something like this (assuming 64bit pointers):
 num_pages = obj_size / 4096
 tree_height = ceil(log64(num_pages))
 num_nodes = sum(64^n, n, 0, tree_height-1)
 tree_size = num_nodes * 576

If we compare that with the object size we should get a relative
overhead of around .2% to 1% for reasonable sized objects,
which framebuffers tend to be.

GVT GEM context is created by i915_gem_context_create_gvt() which
doesn't allocate ppgtt. So GVT GEM context structure doesn't have
a valid i915_hw_ppgtt.

This patch create ppgtt table at GVT GEM context creation, then assign
shadow ppgtt's root table address to this ppgtt when shadow ppgtt will
be used on GPU. So GVT GEM context has valid ppgtt address. But note
that this ppgtt only contain valid ppgtt root table address, the table
entry in this ppgtt structure are invalid.

Fixes:4a3d3f6785be("drm/i915: Match code to comment and enforce ppgtt for execlists")

Subject: drm/i915/icl: Program DSI clock and data lane timing params

This patch programs D-PHY timing parameters for the
clock and data lane (in escape clocks) of DSI
controller (DSI port 0 and 1).
These programmed timings would be used by DSI Controller
to calculate link transition latencies of the data and
clock lanes.

v2: Use newly defined bitfields for data and clock lane

v3 by Jani:
 - Rebase on dphy abstraction
 - Reduce local variables
 - Remove unrelated comment changes (Ville)
 - Use the same style for range checks as VLV (Ville)
 - Assign, don't OR dphy_reg contents

Subject: drm/i915/icl: Program TA_TIMING_PARAM registers

This patch programs D-PHY timing parameters for the
bus turn around flow(in escape clocks) only if dsi link
frequency <=800 MHz using DPHY_TA_TIMING_PARAM and its
identical register DSI_TA_TIMING_PARAM (inside DSI
Controller within the Display Core).

v2: Changes
    - Don't use KHz() macro (Ville/Jani N)
    - Use newly defined bitfields

v3 by Jani:
 - Use intel_dsi_bitrate() in favor of a new field
 - Remove redundant parens

Subject: drm/i915/icl: Configure DSI transcoders

This patch programs DSI operation mode, pixel format,
BGR info, link calibration etc for the DSI transcoder.
This patch also extract BGR info of the DSI panel from
VBT and save it inside struct intel_dsi which used for
configuring DSI transcoder.

v2: Rebase
v3: Use newly defined bitfields.

v4 by Jani:
 - Use intel_dsi_bitrate()
 - Make bgr_enabled bool
 - Use 0 instead of 0x0
 - Replace DRM_ERROR() with MISSING_CASE() on pixel format and video mode
 - Use is_vid_mode()

Subject: drm/i915/guc: Limit number of scratch registers used for H2G

We wrongly assumed that GuC is only using last scratch register
for G2H messages, but in fact it is also using register [14] to
report sleep state status. Remove that register from our H2G
send registers pool.

v2: No message from host to GuC uses more than 8 registers and
the GuC FW itself uses an 8-element array to store the H2G message,
so we may reduce our send array to just 8 registers (Daniele)
v3: use explicit define (Daniele)
v4: and explicit comment (Daniele)

Subject: drm/i915/icl: Define TRANS_DDI_FUNC_CTL DSI registers

This patch defines TRANS_DDI_FUNC_CTL and TRANS_DDI_FUNC_CTL2
registers and their bitfields for DSI. These registers are used
for enabling port sync mode, input pipe select, data lane width
configuration etc.

v2: Changes:
    - Remove redundant extra line
    - Correct some of bitfield definition

v3 by Jani:
 - Move DSI transcoder offsets to GEN11_FEATURES

Subject: drm/i915/icl: Define TRANS_CONF register for DSI

This patch defines TRANS_CONF registers for DSI ports
0 and 1. Bitfields of these registers used for enabling
and reading the current state of transcoder.

v2: Add blank line before comment

v3 by Jani:
 - Move DSI specific .pipe_offsets to GEN11_FEATURES
 - Macro placement and comment juggling

Just sorting this "if" block from newer to older platform.

The main difference here is the addition of a
missing case with return false that should never occur.
And if it occurs it is better than to raise a warn
than use the icl one.

The gen >= 11 was already present in the previous logic,
although hidden.

So, in summary no real functional change.

The 2 functions don't create or destroy anything, they just update the

Subject: drm/i915/guc: doorbell checking cleanup

A collection of very small cleanups/improvements around doorbell checking
that do not deserve their own patch:

- Move doorbell-related HW defs to intel_guc_reg.h

- use GUC_NUM_DOORBELLS instead of GUC_DOORBELL_INVALID where
  appropriate

- do not stop on error in guc_verify_doorbells

- do not print drbreg on error: the only content of the register
  apart from the valid bit is the lower part of the physical memory
  address, which we can't use even if valid because we don't know
  which descriptor it came from (since the doorbell is in an unexpected
  state)

- Move the checking of doorbell valid bit to a common helper.

v2: add more cleanups (move defs, use GUC_NUM_DOORBELLS, don't stop in
    guc_verify_doorbells) (Michal)

v3: move more things to intel_guc_reg, redefine
    GUC_DOORBELL_INVALID (Michal), drop guc_doorbell_qw since it just
    duplicates guc_doorbell_info

commit e346a991f42c ("drm/i915/guc: drop negative doorbell alloc

code between the goto from the positive case of the test and the label
itself, so we can get rid of it.

Subject: drm/i915/perf: remove redundant oa buffer initialization

We initialize the OA buffer everytime we enable the OA unit (first call in
gen[78]_oa_enable), so we don't need to initialize when preparing the metric
set.

Subject: drm/i915/perf: add a parameter to control the size of OA buffer

The way our hardware is designed doesn't seem to let us use the
MI_RECORD_PERF_COUNT command without setting up a circular buffer.

In the case where the user didn't request OA reports to be available
through the i915 perf stream, we can set the OA buffer to the minimum
size to avoid consuming memory which won't be used by the driver.

v2: Simplify oa buffer size exponent selection (Chris)
    Reuse vma size field (Lionel)

v3: Restrict size opening parameter to values supported by HW (Chris)

v4: Drop out of date comment (Matt)
    Add debug message when buffer size is rejected (Matt)

Subject: drm/i915: Relocate SKL+ NV12 src width w/a
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The SKL+ NV12 src width alignment w/a is still living in an odd place.
Everything else was already relocated closer to the main plane check
function. Move this workaround as well.

As a bonus we avoid the funky rotated vs. not mess with the src
coordinates as this now gets checked before we rotate the coordinates.

Subject: drm/i915: Move the SKL+ zero constant alpha handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Let's run through the entire plane check even when the plane
is invisible due to zero constant alpha. This makes for more
consistent behaviour since we check the src/dst coordinates,
stride etc. against the hardware limits.

Propagate the timeout on transferring the fw back to the caller where it

Subject: drm/i915: Move the DDC/AUX failure msgs to debug log

When a HDCP authentication is in progress, if the display sink is
hot unplugged, all DDC/AUX transaction related to the HDCP
authentication will fail.

This patch moves those kind of HDCP DDC/AUX failures into the debug
logs instead of errors.

v2:
  Bksv invalid state is provided as debug msg

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

On gen11, we can definitely smash the 32-bits barrier with just a
when we enable all planes in the next patch.

Changes since v1:
- Use div64_u64 (ickle).

Subject: drm/i915/gen11: Link nv12 Y and UV planes in the atomic state, v5.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To make NV12 working on icl, we need to update 2 planes simultaneously.
I've chosen to do this in the CRTC step after plane validation is done,
so we know what planes are (in)visible. The linked Y plane will get
updated in intel_plane_update_planes_on_crtc(), by the call to
update_slave, which gets the master's plane_state as argument.

The link requires both planes for atomic_update to work,
so make sure skl_ddb_add_affected_planes() adds both states.

Changes since v1:
- Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers.
- Put all the state updating login in intel_plane_atomic_check_with_state().
- Clean up changes in intel_plane_atomic_check().
Changes since v2:
- Fix intel_atomic_get_old_plane_state() to actually return old state.
- Move visibility changes to preparation patch.
- Only try to find a Y plane on gen11, earlier platforms only require
  a single plane.
Changes since v3:
- Fix checkpatch warning about to_intel_crtc() usage.
- Add affected planes from icl_add_linked_planes() before check_planes(),
  it's a cleaner way to do this. (Ville)
Changes since v4:
- Clear plane links in icl_check_nv12_planes() for clarity.
- Only pass crtc_state to icl_check_nv12_planes().
- Use for_each_new_intel_plane_in_state() in icl_check_nv12_planes.
- Rename aux to linked. (Ville)

From b048a00b3d9635141c7b1d4eabf6cff869a92238 Mon Sep 17 00:00:00 2001
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Thu, 18 Oct 2018 13:51:30 +0200
Subject: drm/i915/gen11: Handle watermarks correctly for separate Y/UV planes,
 v2.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Skylake style watermarks program the UV parameters into wm->uv_wm,
and have a separate DDB allocation for UV blocks into the same plane.

Gen11 watermarks have a separate plane for Y and UV, with separate
mechanisms. The simplest way to make it work is to keep the current
way of programming watermarks and calculate the Y and UV plane
watermarks from the master plane.

Changes since v1:
- Constify crtc_state where possible.
- Make separate paths for planar formats in skl_build_pipe_wm() (Matt)
- Make separate paths for calculating total data rate. (Matt)
- Make sure UV watermarks are unused on gen11+ by adding a WARN. (Matt)

From b1554e23ccb6d8e611c5d54ca94bb2dfc54cae72 Mon Sep 17 00:00:00 2001
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Thu, 18 Oct 2018 13:51:31 +0200
Subject: drm/i915/gen11: Program the scalers correctly for planar formats, v3.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma
upsampler to upscale YUV420 to YUV444 and the scaler should only be
used for upscaling. Because of this we shouldn't program the scalers
in planar mode if NV12 and the chroma upsampler are used. Instead
program the scalers like on normal planes.

Sprite 2 and 3 have no dedicated scaler, and need to program the
selected Y plane in the scaler mode.

Changes since v1:
- Make the comment less confusing.
Changes since v2:
- Fix checkpatch warning (Matt)
- gen10- -> Pre-gen11 (Ville)
- PS_SCALER_MODE_PACKED -> PS_SCALER_MODE_NORMAL. (Matt)
- Add comment about scaler mode in intel_atomic_setup_scaler(). (Matt)
- Rename need_scaling to need_scaler. (Matt)
- Move the crtc need_scaling check to skl_update_scaler_crtc().

We configure the chroma upsampler with the same chroma siting as
used by the scaler for consistency, the chroma upsampler is used
instead of the scaler for YUV 4:2:0 on ICL's HDR planes.

Subject: drm/i915/gen11: Program the Y and UV plane for planar mode correctly,
 v3.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The UV plane is the master plane that does all color correction etc.
It needs to be programmed with the dimensions for color plane 1 (UV).

The Y plane just feeds the Y pixels to it. Program the scaler from the
master only, and set PLANE_CTL_YUV420_Y_PLANE on the slave plane.

Changes since v1:
- Make a common skl_program_plane, and use it for both plane updates.
Changes since v2:
- Make color_plane explicit, to clarify skl_update_plane(). (Ville)

Subject: drm/i915: Don't apply the 16Gb DIMM wm latency w/a to BXT/GLK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.

This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

v2: Do the check when populating is_16gb_dimm (Mahesh)

Subject: drm/i915: Ensure proper HDA suspend/resume ordering with a device
 link
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In order to ensure that our system suspend and resume callbacks are
called in the correct order wrt. those of the HDA driver add a device
link to the HDA driver during audio component binding time. With i915 as
the supplier and HDA as the consumer the PM framework will guarantee
the HDA->i915 suspend (and shutdown) and i915->HDA resume order.

Atm, the lack of this ordering is not a problem, since all the i915
suspend/resume steps that need to be ordered wrt. the HDA driver's
suspend/resume steps are separated out to the i915
suspend_late/resume_early hooks. That will change in a follow-up
patchset where we'll need this ordering guarantee for steps that are in
the i915 suspend/resume hooks (and which can't be moved to
suspend_late/resume_early for other reasons). So this patch is a
preparation for that follow-up patchset.

The change also allows us to move towards removing the i915
suspend_late/resume_early hooks alltogether.

Since we only need to ensure the ordering during suspend/resume and not
during driver probing create the link with DL_FLAG_STATELESS. Since the
probe time ordering has to be optional we use the component framework
for that.

Similarly for runtime PM we depend on the audio driver getting/putting
an i915 runtime PM reference whenever it needs it (along with the proper
i915 display power domain) via the audio component ops get_power /
put_power hooks. So we create the device link without
DL_FLAG_PM_RUNTIME.

v2: (Ville)
- Add a note to the commit message about not using the device link
  runtime PM ordering.
- Handle the error return from device_link_add().

Subject: drm/i915/selftests: Check for hangs mid context execution tests

Use the live_test struct to record the reset count before and compare it
at the end of the test to assert that no mystery hang occurred during the
test.

v2: Check per-engine resets as well

Subject: drm/i915: Park signaling thread while wrapping the seqno

A danger encountered when resetting the seqno (using
debugfs/i915_next_seqno) is that as we change the breadcrumb stored in
the HWSP, it may be inspected by the signaler thread leading to
confusion in our sanity checks.

Subject: drm/i915: wrapping all hdcp var into intel_hdcp

Considering significant number of HDCP specific variables, it will
be clean to have separate struct for HDCP.

New structure called intel_hdcp is added within intel_connector.

v2:
  struct hdcp statically allocated. [Sean Paul]
  enable and disable function parameters are retained.[Sean Paul]
v3:
  No Changes.
v4:
  Commit msg is rephrased [Uma]
v5:
  Comment for mutex definition.
v6:
  hdcp_ prefix from all intel_hdcp members are removed [Sean Paul]
  inline function intel_hdcp_to_connector is defined [Sean Paul]
v7:
  %s/uint64_t/u64
v8:
  Rebased

Subject: drm/i915: Reassigning log level for HDCP failures

As a policy, this change considers all I915 programming failures and
HW failures as ERRORS. Where as all HDCP failures due to the sink is
considered as DEBUG logs.

MIME-Version: 1.0

Whenever possible we should stick with IS_GEN<n> checks.

Bitmaks has been introduced on commit ae7617f0ef18 ("drm/i915:
Allow optimized platform checks") for efficiency.

Let's stick with it whenever possible.

Subject: drm/i915: Kill GEN_FOREVER

commit ac657f6461e5 ("drm/i915: Introduce IS_GEN macro") introduced
GEN_FOREVER that was never used.

My first attempt was to rename it to FOREVER since GEN is
already part of the macro. Then I used coccinelle to change all
-INTEL_GEN(e1) >= e2
+INTEL_GEN_RANGE(e1, e2, FOREVER)
-INTEL_GEN(e1) <= e2
+INTEL_GEN_RANGE(e1, 0, e2)

and I liked it.

However I didn't like very much the remaining
INTEL_GEN(dev_priv) < n

and:
INTEL_GEN(e1) < n
INTEL_GEN_RANGE(e1, 0, n - 1)

didn't make much sense either.

So INTEL_GEN use for > or < seems a better unified way for unlimited
bounds. So, no reason to keep GEN_FOREVER here.

Let's kill before someone start using it.

v2: Remove remaining GEN_FOREVER forgotten in a comment. (Daniel)

Subject: drm/i915/glk: Remove 99% limitation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.

So I got the confirmation from HW architect that we actually
never needed this workaround.

"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."

So, this reverts commit 97f55ca5b662 ("drm/i915/glk: limit pixel
 clock to 99% of cdclk workaround")

Fixes: 97f55ca5b662 ("drm/i915/glk: limit pixel clock to 99% of cdclk workaround")

Subject: drm/i915/selftests: Test vm isolation

The vm of two contexts are supposed to be independent, such that a stray
write by one cannot be detected by another. Normally the GTT is filled
explicitly by userspace, but the space in between objects is filled with
a scratch page -- and that scratch page should not be able to form an
inter-context backchannel.

Subject: drm/i915: Simplify has_sagv function

The specially case for SKL for not controlled sagv
is already taken care inside intel_enable_sagv, so there's
no need to duplicate the check here.

v2: Go one step further and remove skl special case. (Jani)
v3: Separate runtime status handle from has_sagv flag.
v4: Go back and accept simple Jani proposed solution.

intel_fb_pitch_limit() has the parameters pixel_format and fb_modifier

Also use kernel data types for both parameters.

Subject: drm/i915/gtt: Record the scratch pte

Record the scratch PTE encoding upon creation rather than recomputing
the bits everytime. This is important for the next patch where we forgo
having a valid scratch page with which we may compute the bits and so
require keeping the PTE value instead.

v2: Fix up scrub_64K to use scratch_pte as well.

Subject: drm/i915/gtt: Reuse the read-only 64KiB scratch page and directories

If we can prevent stray writes from landing in the scratch page, we can
reuse the same page and same scratch PT for all contexts without fear of
information leaks and side-channels.

Subject: drm/i915: Stop calling intel_opregion unregister/register in
 suspend/resume

If we reduce the suspend function for intel_opregion to do the minimum
required, the resume function can also do the simple task of notifier
the ACPI bios that we are back. This avoid some nasty restrictions on
the likes of register_acpi_notifier() that are not allowed during the
early phase of resume.

v2: Keep the order of acpi notify vs turning off ardy/drdy the same.

Subject: drm/i915/icl: Enable DC9 as lowest possible state during screen-off

ICL supports DC5, DC6, and DC9. Enable DC9 during screen-off, and enable
DC5/6 when appropriate.

v2: (James Ausmus)
 - Also handle ICL as GEN9_LP in i915_drm_suspend_late and
   i915_drm_suspend_early
 - Add DC9 to gen9_dc_mask for ICL
 - Re-order GEN checks for newest platform first
 - Use INTEL_GEN instead of INTEL_INFO->gen
 - Use INTEL_GEN >= 11 instead of IS_ICELAKE
 - Consolidate GEN checks

v3: (James Ausmus)
 - Also allow DC6 for ICL (Imre, Art)
 - Simplify !(GEN >= 11) to GEN < 11 (Imre)

v4: (James Ausmus)
 - Don't call intel_power_sequencer_reset after DC9 for Gen11+, as the
   PPS regs are Always On
 - Rebase against upstream changes

v5: (Anusha Srivatsa)
- rebased against the latest upstream changes.

v6: (Anusha Srivatsa)
- rebased.Use INTEL_GEN consistently.
- Simplify the code (Rodrigo)

v7: rebased. Change order according to platforms(Jyoti)

v8: rebased. Change the check from platform specific to
HAS_PCH_SPLIT(). Add comment in code to be more clear.(Rodrigo)

This reverts commit c9e666880de5a1fed04dc412b046916d542b72dd.

Checked GVT codes that guest PPGTT PTE flag bits are propagated
to shadow PTE. Read/write bit is not changed. Further tested by
i915 self-test case "igt_ctx_readonly". No error or GPU hang was
detected. So enable read-only support under GVT.

Subject: drm/i915/selftest: test aligned offsets for 64K

When using softpin it's not enough to just pad the vma size, we also
need to ensure the vma offset is at the start of the pt boundary, if we
plan to utilize 64K pages. Therefore to improve test coverage we should
use both aligned and unaligned gtt offsets in igt_write_huge.

Subject: drm/i915/gvt: support inconsecutive partial gtt entry write

Previously we assumed two 4-byte writes to the same PTE coming in sequence.
But recently we observed inconsecutive partial write happening as well. So
this patch enhances the previous solution. It now uses a list to save more
partial writes. If one partial write can be combined with another one in
the list to construct a full PTE, update its shadow entry. Otherwise, save
the partial write in the list.

v2: invalidate old entry and flush ggtt (Zhenyu)
v3: split old ggtt page unmap to another patch (Zhenyu)
v4: refine codes (Zhenyu)

Subject: drm/i915/gvt: Handle values of EDP_PSR_IMR and EDP_PSR_IIR

GVT-g only simulates DP port for guest and leaves EDP_PSR_IMR
and EDP_PSR_IIR registers as default MMIO read/write.
So guest won't get expected initial values of these registers when
initializing the gpu driver, which results in following warning and logs.

--------
Interrupt register 0x64838 is not zero: 0xffffffff
WARNING: CPU: 1 PID: 157 at drivers/gpu/drm/i915/i915_irq.c:177
gen3_assert_iir_is_zero+0x38/0xa0

Call Trace:
gen8_de_irq_postinstall+0xa7/0x400
gen8_irq_postinstall+0x27/0x80
drm_irq_install+0xbc/0x140
i915_driver_load+0xa9d/0xd50
--------
Because GVT-g does not handle EDP(embedded DP) simulation for guests,
always set EDP_PSR_IMR and EDP_PSR_IIR to value 0.

Subject: drm/i915/icl: Wait for header/payload credits release

Driver needs payload/header credits for sending any command
and data over DSI link. These credits are released once command
or data sent to link. This patch adds functions to wait for releasing
of payload and header credits.

As per BSPEC, driver needs to ensure that all of commands/data
has been dispatched to panel before the transcoder is enabled.
This patch implement those steps i.e. sending NOP DCS command,
wait for header/payload credit to be released etc.

v2 by Jani:
 - squash the credit wait helpers patch with the first user
 - pass dev_priv to the credit wait helpers
 - bikeshed credit helper names
 - wait for *at least* the current maximum number of credits
 - indentation fix
 - add helpers for credits available

Subject: drm/i915/icl: Program HS_TX_TIMEOUT/LP_RX_TIMEOUT/TA_TIMEOUT
 registers

Program the timeout values (in escape clock) for HS TX, LP RX and TA
timeout.

HX TX: Ensure that host does not continuously transmit in the HS
state. If this timer expires, then host will gracefully end its HS
transmission and allow the link to enter into LP state.

LP RX: Monitor the length of LP receptions from Peripheral. If timeout
happens then host will drive the stop state onto all data lanes (only
Data Lane 0 should be receiving anything from the Peripheral). This
effectively takes back ownership of the bus transmit in the HS state.

TA timeout: Timeout valuefor monitoring Bus Turn-Around (BTA) sequence.
BTA sequence should complete within a bounded amount of time, with
peripheral acknowledging BTA by driving the stop state.

v2 by Jani:
 - Rebase
 - Use intel_dsi_bitrate() and intel_dsi_tlpx_ns(intel_dsi)
 - Squash HX TX, LP RX and TA timeout into one patch
 - Fix bspec mode set sequence reference
 - Add FIXME about two timeouts

Subject: drm/i915/dp: Cache the DP/eDP DSC DPCD register set on Hotplug/eDP
 Init

DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting
GEN 11.
This patch implements the discovery phase of DSC. On hotplug,
source reads the DSC DPCD register set (0x00060 - 0x0006F) to
read the decompression capabilities of the sink device.
This entire block of registers is cached in intel_dp so that
capability information can be used during DSC configuration
phase during compute_config phase of the modeset.
For eDP, this caching happens during the eDP initialization.
This caching is done only for eDP and DP rev >= 1.4

v5:
* Fix the block comment (Gaurav)
* Fix the commit message DSC DPCD addresses (Gaurav)
* Use DRM_ERROR for dpcd_read fail (Gaurav,Anusha)
v4:
* Cache these only for Gen >= 11
v3:
* Remove the dsc_sink_support field in intel_dp (Jani N)
v2:
* Clear the cached registers on hotplug always (Jani N)
* Combine the eDP and DP caching in same function (Jani N)

Subject: drm/i915/dp: Add helpers for Compressed BPP and Slice Count for DSC

This patch adds helpers for calculating the maximum compressed BPP
supported with small joiner.
This also adds a helper for calculating the slice count in case
of small joiner.
These are inside intel_dp since they take into account hardware
limitations.

v6:
* Take mode_clock and mode_hdisplay as input arguments
so that this can be called in intel_dp_mode_valid (Manasi)
v5:
* Get the max slice width from DPCD
* Check against Min_Slice_width of 2560 (Anusha)
v4:
* #defines for PPR in slice count helper (Gaurav)
v3:
* Simply logic for bpp (DK)
* Limit the valid slice count by max supported by Sink (Manasi)
v2:
* Change the small joiner RAM buffer constant as bspec changed (Manasi)
* rename it as SMALL_JOINER since we are not enabling
big joiner yet (Anusha)

Subject: drm/i915/dp: Validate modes using max Output BPP and slice count when
 DSC supported

When DSC is supported we need to validate the modes based on the
maximum supported compressed BPP and maximum supported slice count.
This allows us to allow the modes with pixel clock greater than the
available link BW as long as it meets the compressed BPP
and slice count requirements.

v3:
* Use the macro for dsc sink support (Jani N)
v2:
* Properly comment why we are right shifting the bpp value (Anusha)

Subject: drm/i915: Use intel_panel_actually_set_backlight() to disable PWM
 backlight
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use intel_panel_actually_set_backlight() instead of a direct
call to pwm_config() in pwm_disable_backlight().

The main benefit is consistent debug logging when we turn off the
backlight. Currently we see nothing in dmesg which made me wonder
whether the backlight was even getting turned off properly.

The second benefit is consistency; This is what we do for all
the other backlight implementations.

Otherwise it would be in a inconsistent state as port is disconnected
but with a valid tc type.

Also setting it to unknown will earlier return
icl_tc_phy_disconnect() for any future calls to
intel_digital_port_connected(), this way we don't need to check if
port is marked as safe everytime.

MST ports are allocated from struct intel_dp_mst_encoder not from
struct intel_digital_port as regular ports, so to get the TC type it
is necessary check the primary digital port of the mst encoder.

Subject: drm/i915/ICL: Add pre_pll_enable hook for ICL and set DFLEXDPMLE in
 this hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In case of Legacy DP connector on TypeC port, the
flex IO DPMLE register is set to number of lanes configured
by the display driver which will be programmed into DDI_BUF_CTL
PORT_WIDTH_SELECTION.
This needs to be programmed before enabling the shared PLLs hence
add a pre_pll_enable hook for ICL and add this programming in that hook.

v2:
* Remove the check for combophy port (Jose)
* Simplify the port reversal check logic (Jose)

Subject: drm/i915/icl: Add DSS_CTL Registers

Add defines for DSS_CTL registers.
These registers specify the big joiner, splitter,
overlap pixels and info regarding
compression enabled on left or right branch.

v2:
- rebase. Remove overlapping defines(James Ausmus)
- Rename the register to ICL_DSS_CTL1/2_PIPE_ (manasi)
- take pixels as an argument for overlap.(Manasi)

v3:
- rebase. merge DSS_CTL1/2 introduced in Madhav's patch
  to avoid confusion (madhav chauhan)
- Rename registers in accordance to BSpec (Madhav, Rodrigo)
- Add define to conditionally check the buffer target depth (James Ausmus)

v4:
- remove redundant definitions.(madhav)

v5:
- Add mask for overlap pixels.
- Code Style changes.(Madhav)
v6:
- Code style changes. (Madhav)

Add missing block that takes care of inline intel_suspend_complete
for DC9 on ICL.

Daniele noticed this was part of original patch but missed on
on merged commit ("drm/i915/icl: Enable DC9 as lowest possible
 state during screen-off").

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

First of all I believe this WA as written here was wrong.

Because it is listed on BSpec only for SKL and BXT, exactly
the only 2 platforms skipped here.

But also it is written there that we don't need this WA
anymore:
"This workaround is no longer needed since NV12 support is
dropped for the affected projects in #0870."

SO, let's kill it.

Let's introduce the WA number that is the
cause of having NV12 disabled on both SLK and BXT.

According to Spec:

WA 0870: "Display flickers with NV12 video playback in
Y tiling mode.
WA: Use YUV422 surface format instead of NV12."

v2: remove the useless dead code and consequently
    avoiding device info flag. (Ville)

Subject: drm/i915: Init aux_ch for HDMI ports too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From ICL onwards DDI/TypeC ports - even in HDMI static mode - need to know
which AUX CH belongs to them, so initialize aux_ch for those ports too.
For consistency do this for all HDMI ports, not only for DDI/TypeC ones.

Subject: drm/i915: Use a helper to get the aux power domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From ICL onwards the AUX power domain may change dynamically based on
whether a DDI/TypeC port is in thunderbolt or non-thunderbolt mode, so
use a helper function instead of a static field to get the current
domain.

Subject: drm/i915: Enable AUX power earlier
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For DDI/TypeC ports the AUX power domain needs to be enabled before the
port's PLL is enabled, so move the enabling earlier accordingly.

v2:
- Preserve the pre_pll hook for GEN9_LP. (Ville)
v3:
- Add related BSpec entries to commit log. (Jose)
v4:
- Rebase on the upstream ICL pre_pll_enable change.

Subject: drm/i915: Enable AUX power for HDMI DDI/TypeC main link too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DDI/TypeC ports need the AUX power domain for main link functionality
even when they operate in HDMI static mode, so enable the power domain
for these ports too.

v4:
- Rebase on the upstream ICL pre_pll_enable change.

Subject: drm/i915: Configure AUX_CH_CTL when enabling the AUX power domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most of the AUX_CH_CTL flags are concerned with DP AUX transfer
parameters. As opposed to this the flag specifying the thunderbolt vs.
non-thunderbolt mode of the port is not related to AUX transfers at all
(rather it's repurposed to enable either TBT or non-TBT PHY HW blocks).
The programming has to be done before enabling the corresponding AUX
power well, so make it part of the power well code.

v3:
- Use existing enable/disable helpers instead of opencoding. (Jose)
- Fix type of is_tc_tbt to remain a bitfield. (Lucas)
- Add comment describing the is_tc_tbt power well flag. (Lucas)

Subject: drm/i915/icl: Fix DSS_CTL register names

This patch fixes the naming of the registers:

s/PIPE_DSS_CTL/ICL_PIPE_DSS_CTL

And also fix the hex values to lower case, to match
rest of the definitions.

Manasi noticed this with the patch that was merged.

Subject: drm/i915: remove palette_offsets from device info in favor of _PICK()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.

While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Remove unused old palette macros while at it.

Bloat-o-meter results below for completeness.

Subject: drm: Add connector property to limit max bpc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At times 12bpc HDMI cannot be driven due to faulty cables, dongles
level shifters etc. To workaround them we may need to drive the output
at a lower bpc. Currently the user space does not have a way to limit
the bpc. The default bpc to be programmed is decided by the driver and
is run against connector limitations.

Creating a new connector property "max bpc" in order to limit the bpc.
xrandr can make use of this connector property to make sure that bpc does
not exceed the configured value. This property can be used by userspace to
set the bpc.

V2: Initialize max_bpc to satisfy kms_properties
V3: Move the property to drm_connector
V4: Split drm and i915 components(Ville)
V5: Make the property per connector(Ville)
V6: Compare the requested bpc to connector bpc(Daniel)
    Move the attach_property function to core(Ville)
V7: Fix checkpatch warnings
V8: Simplify the connector check code(Ville)
V9: Const display_info(Ville)
V10,V11: Fix CI issues.
V12: Add the Kernel documentation(Daniel)
V14: Crossreference the function name in the doc(Daniel)

Subject: drm/i915/fia: FIA registers offset implementation.

The registers DPCSSS,DPSP,DPMLE1 and DPPMS are all at an offset
from the base - which is the FLexi IO Adaptor. Lets follow the
offset calculation while accessing these registers.

v2:
- Follow spec for numbering - s/0/1(Lucas)
- s/FIA_1/FIA1_BASE (Anusha)

v3:
- Remove register offset defines. (Jani)
- Update comment. (Anusha)

v4: rebase. Remove comment.(Lucas)

Subject: i915/dp/fec: Cache the FEC_CAPABLE DPCD register

Similar to DSC DPCD registers, let us cache
FEC_CAPABLE register to avoid using stale
values. With this we can avoid aux reads
everytime and instead read the cached values.

v2: Avoid using memset and array for a single
field. (Manasi,Jani)

v3: Print FEC CAPABILITY value. (Manasi)

Subject: Revert "drm/exynos/decon5433: implement frame counter"

This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b

This patch makes it to need get_vblank_counter callback in crtc
to get frame counter from decon driver.

However, drm_dev->max_vblank_count is a member unique to
vendor's DRM driver but in case of ARM DRM, some CRTC devices
don't provide the frame counter value. As a result, this patch
made extension and clone mode not working.

Instead of this patch, we may need separated max_vblank_count
which belongs to each CRTC device, or need to implement frame
counter emulation for them who don't support HW frame counter.

Since connectors can be created dynamically, fbdev should be initialized
even if there are no connectors at the moment. Otherwise fbdev will
not be created even after connector's appearance.
The patch fixes lack of fbdev on rinato and trats boards.

Subject: drm/i915/icl: Configure MG PHY gating for HDMI ports too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The MG PHY clock gating needs to be configured for Type C
static/fixed/legacy HDMI ports the same way it's configured for Type C
static/fixed/legacy and aternate mode DP ports, fix this.

Subject: vga_switcheroo: Fix missing gpu_bound call at audio client
 registration

The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound.  The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound.  When an audio client is registered
after that point, it would miss the gpu_bound call.  This leads to the
unexpected lack of runtime PM in HD-audio side.

For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=201615

Subject: drm/i915/gen9_lp: Fix DMC DC counter debugfs output

On GEN9 LP (BXT/GLK) DC6 is not supported, so don't print the counter
on those platforms. So far we did this on GLK too.

While at it warn if we forgot to adjust the printout properly for a
new platform. (Rodrigo)

Subject: drm/etnaviv: fix bogus fence complete check in timeout handler

The GPU hardware fences and the job out-fences are on different timelines
so it's wrong to compare them. Fix this by only looking at the out-fence.

This is done to clear up the clock programming sequence
since the only time we need to notify pplib is after
clock update.

This also renames the clk block to dccg, at the moment
this block contains both clock management and dccg
functionality.

From 9566b67586fb1d96c36207fd975087d68296755c Mon Sep 17 00:00:00 2001
From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>
Date: Tue, 18 Sep 2018 15:00:49 -0400
Subject: drm/amd/display: remove safe_to_lower flag from dc, use 2 functions
 instead

This is done to keep things more readable, avoids a true/false flag
in dc interface layer.

Subject: drm/amd/display: Freesync does not engage on some displays

[Why]
Current render margin time is not sufficient to compute exit frame
time for most monitors.

[How]
Declared  render margin in FPS to compute a exit frame rate that is
4 FPS above the minimum FPS required to engage FreeSync.
 Also did code clean-up to remove redundancies.

Subject: drm/amd/display: Add support for Freesync 2 HDR and Content to
 Display Mapping

[Why]
Freesync 2 HDR and support for HDR content
outside the range of the HDR display
require implementation on Dal 3 to better match
Dal2.

[How]
Add support for Freesync HDR and mapping
of source content to display ranges for better
representation of HDR content.

Subject: drm/amd/display: fix report display count logic

[Why]
Previous logic to update display count in commit_planes_do_stream_update
doesn't cover all cases.

[How]
Update display count as part of clock updates. Count virtual stream
as active to work around headless situation.

Subject: drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h -
 part1

[Why]
In DCN we want direct DAL to SMU calls, with as little as possible
interference by pplib. The reason for each pp_smu interface mapping
to 1 SMU message is so we can have the sequencing of different SMU
message in dal and shared across different OS. This will also simplify
debugging as DAL owns this interaction and there's no confusion about
division of ownership.

[How]
Part 1: Separate set_min_deep_Sleep_dcfclk message from the SMU
messages that are sent as part of dcn10_pplib_apply_display_requirements.
Notify deep sleep dcfclk to smu directly

Subject: drm/amd/display: rename dccg to clk_mgr

In preparation for adding the actual dccg block since the
current implementation of dccg is mor eof a clock manager
than a hw block

Subject: drm/ttm: Rename ttm_bo_global_{init,release}() to
 ttm_bo_global_ref_{,}()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The functions ttm_bo_global_init() and ttm_bo_global_release() do not
receive an argument of type struct ttm_bo_global. Both take a struct
drm_global_reference that contains points to a struct ttm_bo_global_ref.
Renaming them reflects this.

Subject: drm/ttm: Provide ttm_bo_global_{init/release}() for struct
 ttm_bo_global
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So far, struct ttm_bo_global_ref was the only way of initializing a struct
ttm_bo_global. Providing separate initializer and release functions for
struct ttm_bo_global gives drivers the option of implementing their own
init and release callbacks for drm_global_references of type
DRM_GLOBAL_TTM_BO.

The original functions for initializing and releasing via struct
ttm_bo_global_ref are wrappers around the new interfaces.

Subject: drm/amdgpu: fix sdma v4 ring is disabled accidently

For sdma v4, there is bug caused by
commit d4e869b6b5d6 ("drm/amdgpu: add ring test for page queue")'

local variable ring is reused and changed, so amdgpu_ttm_set_buffer_funcs_status(adev, true)
is skipped accidently. As a result, amdgpu_fill_buffer() will fail, kernel message:

Subject: drm/amdgpu: use scheduler fault instead of reset work
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Signal a fault to the scheduler on an illegal instruction or register
access violation instead of kicking of the reset handler directly.

Subject: drm/amdkfd: Delete unnecessary register settings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Those register settings have been performed in amdgpu initialization
gfxhub_v1_0_setup_vmid_config() and mmhub_v1_0_setup_vmid_config().
So no need to do it again in kfd.

After amdkfd module is merged into amdgpu, KFD can call amdgpu directly
and no longer needs to use the function pointer. Replace those function
pointers with functions if they are not ASIC dependent.

Subject: drm/amd/display: Remove stream_res tg null check in commit planes

[Why]
TG in pipe_ctx stream resource is not null where used in
commit_planes_do_stream_update since it is assigned the
same time the stream is set in pipe_ctx - when the pipe is
acquired. This null check produced a static code analysis
warning and should be removed to avoid similar unnecessary
checks in the future.

[How]
Remove the null check.

Subject: drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h -
 part3

[Why]
In DCN we want direct DAL to SMU calls, with as little as
possible interference by pplib. The reason for each pp_smu interface
mapping to 1 SMU message is so we can have the sequencing of different
SMU message in dal and shared across different OS. This will also
simplify debugging as DAL owns this interaction and there's no
confusion about division of ownership.

[How]
Separate the set_hard_min_fclk_by_freq message from the
SMU messages that are sent as part of pp_rv_set_display_requirement.
directly notify min dcfclk to smu part 2

Subject: drm/amdkfd: Use functions from amdgpu to invalidate vmid in kfd
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As part of the change, we stop taking the srbm lock, and start to use
the same invalidation engine and software lock as amdgpu.

MIME-Version: 1.0

As the name says we only need one global instance of ttm_mem_global.

Drop all the driver initialization and just use a single exported
instance which is initialized during BO global initialization.

As the name says we only need one global instance of ttm_bo_global.

Just use a single exported instance which is save to initialize multiple times.

Subject: drm/ttm: initialize globals during device init (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make sure that the global BO state is always correctly initialized.

This allows removing all the device code to initialize it.

v2: fix up vbox (Alex)

Subject: drm/sched: Add boolean to mark if sched is ready to work v5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:
A particular scheduler may become unsuable (underlying HW) after
some event (e.g. GPU reset). If it's later chosen by
the get free sched. policy a command will fail to be
submitted.

Fix:
Add a driver specific callback to report the sched status so
rq with bad sched can be avoided in favor of working one or
none in which case job init will fail.

v2: Switch from driver callback to flag in scheduler.

v3: rebase

v4: Remove ready paramter from drm_sched_init, set
uncoditionally to true once init done.

v5: fix missed change in v3d in v4 (Alex)

From c66ed765a0a97b8900f37d4a71f1d75f52f56eeb Mon Sep 17 00:00:00 2001
From: Andrey Grodzovsky <andrey.grodzovsky@amd.com>
Date: Fri, 19 Oct 2018 16:22:48 -0400
Subject: drm/amdgpu: Retire amdgpu_ring.ready flag v4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Start using drm_gpu_scheduler.ready isntead.

v3:
Add helper function to run ring test and set
sched.ready flag status accordingly, clean explicit
sched.ready sets from the IP specific files.

v4: Add kerneldoc and rebase.

Subject: drm/amdgpu: Enable default GPU reset for dGPU on gfx8/9 v3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After testing looks like these subset of ASICs has GPU reset
working for the most part. Enable reset due to job timeout.

v2: Switch from GFX version to ASIC type.
v3: Fix identation

Subject: drm/amdgpu: further ring test cleanups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move all error messages from IP specific code into the common helper.
This way we now uses the ring name in the messages instead of the index
and note which device is affected as well.

Also cleanup error handling in the IP specific code and consequently use
ETIMEDOUT when the ring test timed out.

Test only initialized rings, use the ring name instead of the index in the
error message and note on which device the error occured.

Subject: drm/amdgpu: cleanup skipping IB test on KIQ
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of hard coding the ring type in the function just never provide
a test_ib callback.

Additional to that remove the emit_ib callback to make sure the nobody
ever tries to execute an IB on the KIQ.

From 26efecf9558895a89c2920d258601b4afba10fd0 Mon Sep 17 00:00:00 2001
From: Sharat Masetty <smasetty@codeaurora.org>
Date: Mon, 29 Oct 2018 15:02:28 +0530
Subject: drm/scheduler: Add drm_sched_job_cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds a new API to clean up the scheduler job resources. This
is primarliy needed in cases the job was created but was not queued to
the scheduler queue. Additionally with this change, the layer which
creates the scheduler job also gets to free up the job's resources and
this entails moving the dma_fence_put(finished_fence) to the drivers
ops free handler routines.

Subject: drm/amd/display: Set gamma not working on MPO planes

[Why]
Set gamma not working on certain planes in MPO configuration
Root cause is that video format (YUV-420) isn't allowed for IGAM where
gamma is applied.
Fix is not easy though:
1. allowing will not work because IGAM is before ICSC so RGB gamma would
be applied on YUV pixels.
2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts.

Ultimately the root cause for these artifacts was due to handling end
points and the fact that YUV->RGB conversion will frequently "overshoot"
FP 1.0 value. DCE  has a single end point and slope, so we would take max.
In nightlight mode, blue channel is reduced, sometimes to flat 0 line,
but red is virtually unchanged. Any "overshot" in blue will be clipped
to 1 (max R,G,B) instead of max blue value.

[How]
Fortunately, this can be fixed on DCN where we have end point and slope
for all three color channels. We cannot fix this problem on DCE.

Other things fixed:
- switch (back) to using RGAM for OS gamma instead of IGAM
- add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions)
- switch color temperature method to scaled bradford - otherwise we would
have clipping problems that caused us to switch to IGAM for OS gamma
in the first place.
- comments and some minor improvements - there are some more issues but
they will be addressed in separate commits.

Subject: drm/amd/display: Clip all remaining regamma points after first
 clipped point

[Why]
All values computed in the gamma curve after the first upperbound
clipped point will need to be clipped anyways. We can avoid
unnecessary computations and potential fixed point
overflow by instead clipping these values to 1 automatically.

[How]
Track if upper-bound clipping has been done, and clip all values after

Subject: drm/amd/display: fix dml max voltage state

Gabe's formula sometimes uses values from non-existent 'unsupported'
state to do validation.

This change adds this extra state so validation can work correctly.

Subject: drm/amd/display: Initial documentation for AMDgpu DC

[Why]
Documentation is helpful for the community to understand our code.
This change does some high-level documentation of some DM interfaces
with DRM, and the amdgpu base driver.

[How]
An entry for AMDgpu DC has been added to Documentation/gpu/drivers.rst
TOC. amdgpu-dc.rst is created to pull in inline doc-strings, which:
- Provides an overview for "What is DM?"
- Documents AMDgpu DM lifecyle
- Documents IRQ management
- Documents atomic_check and commit_tail interfaces

+===================================
+drm/amd/display - Display Core (DC)
+===================================
+
+*placeholder - general description of supported platforms, what dc is, etc.*
+
+Because it is partially shared with other operating systems, the Display Core
+Driver is divided in two pieces.
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+   hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+   amdgpu base driver and DRM are implemented here.
+
+It doesn't help that the entire package is frequently referred to as DC. But
+with the context in mind, it should be clear.
+
+When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
+supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
+Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
+
+To determine if DC is loaded, search dmesg for the following entry:
+
+``Display Core initialized with <version number here>``

+ * DOC: overview
+ *
+ * DM provides another layer of IRQ management on top of what the base driver
+ * already provides. This is something that could be cleaned up, and is a
+ * future TODO item.
+ *
+ * The base driver provides IRQ source registration with DRM, handler
+ * registration into the base driver's IRQ table, and a handler callback
+ * amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
+ * handler looks up the IRQ table, and calls the respective
+ * &amdgpu_irq_src_funcs.process hookups.
+ *
+ * What DM provides on top are two IRQ tables specifically for top-half and
+ * bottom-half IRQ handling, with the bottom-half implementing workqueues:
+ *
+ * - &amdgpu_display_manager.irq_handler_list_high_tab
+ * - &amdgpu_display_manager.irq_handler_list_low_tab
+ *
+ * They override the base driver's IRQ table, and the effect can be seen
+ * in the hooks that DM provides for &amdgpu_irq_src_funcs.process. They
+ * are all set to the DM generic handler amdgpu_dm_irq_handler(), which looks up
+ * DM's IRQ tables. However, in order for base driver to recognize this hook, DM
+ * still needs to register the IRQ with the base driver. See
+ * dce110_register_irq_handlers() and dcn10_register_irq_handlers().
+ *
+ * To expose DC's hardware interrupt toggle to the base driver, DM implements
+ * &amdgpu_irq_src_funcs.set hooks. Base driver calls it through
+ * amdgpu_irq_update() to enable or disable the interrupt.

Subject: drm/amd/display: Expand dc to use 16.16 bit backlight

[Why] We want to increase precision for backlight setting.
But DC interface takes 8 bit backlight level value only.

[How] DMCU already takes 16 bit backlight level.
Expand the DC interface to take 16.16 bit value.
Max 32 bit backlight value (0xFFFF) will represent
max backlight (100%)

[Why] On DCN1/DCE, There are two functions programming OCSC:
program_csc_matrix and program_output_csc. They do the same thing.

[How] Consolidate to use only program_output_csc.

From ba7b267a458e133cbd791c818fb4cb41180242c6 Mon Sep 17 00:00:00 2001
From: Fatemeh Darbehani <fatemeh.darbehani@amd.com>
Date: Fri, 5 Oct 2018 17:22:32 -0400
Subject: drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h -
 part4

[Why]
In DCN we want direct DC to SMU calls, with minimal interference from
pplib.
The reason for each pp_smu interface mapping to 1 SMU message is so we
can have the sequencing of different SMU message in DC and shared across
different OS's.
This will also simplify debugging as DAL owns this interaction and
there's no confusion about division of ownership.

[How]
Part 4: Change clock units so they match the values PPLib sends to SMU.

Subject: drm/amd/display: Guard against null stream_state in set_crc_source

[Why]

The igt@kms_plane@pixel-format-pipe tests can create a sequence where
stream_state is NULL during amdgpu_dm_crtc_set_crc_source which results
in a null pointer dereference.

[How]

Guard against stream_state being NULL before accessing its fields. This
doesn't fix the root cause of the issue so a DRM_ERROR is generated
to still fail the tests.

Subject: drm/amd/display: Expose target backlight level

[Why]
DM may want to understand any backlight optimizations
applied, so DM needs a way to query from the HW both
the real current backlight, which may be value during
transition.
And also target backlight, which may be after some
backlight optimizations applied.

[How]
Add interface to query current and target backlight levels
Target level may indicate backlight level after backlight
optimization and reductions are applied.

Subject: drm/amd/display: Remove the check to see if pp_display_cfg is changed

[Why]
When going to full-screen mode commit_planes_for_stream tries to decrease
dcf_deep_sleep value, but safe_to_lower is false, so we don't send the new value
to SMU but dc context gets updated.
Later when dc_post_update_surfaces_to_stream tries to lower dcf_ds when
safe_to_lower is true, this check prevents the message from being sent.

[How]
Remove the check that compares new value with what is stored in dc_context.
This check is not necessary as dcn1_update_clocks already checks if the value
is different from the current dcf_dp value.

There is no functional changes,
Use function arguments for SRIOV special variables which
is hardcode in those functions.

so we can share those functions in baremetal.

Subject: drm/amdgpu: Modify the argument of emit_ib interface

use the point of struct amdgpu_job as the function
argument instand of vmid, so the other members of
struct amdgpu_job can be visit in emit_ib function.

v2: add a wrapper for getting the VMID
    add the job before the ib on the parameter list.
v3: refine the wrapper name

Subject: drm/i915: Fix ilk+ watermarks when disabling pipes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).

This seems to have been broken by commit b6b178a77210 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.

Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

Subject: drm/amdgpu: Refine function name

there is no functional changes.just
refine function name to keep
consistence with other files.

change amdgpu_get_sdma_instance to
amdgpu_sdma_get_instance_from_ring.
suggested by alex.

Subject: drm/i915/icl: Define Plane Input CSC Coefficient Registers

Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.

v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.

v3: Removed a redundant 3rd Pipe register definition and
simplified the equally spaced register definition by adding an
offset as per Matt's comment.

v4: No Change

v5: Renamed the register Macro as per Matt's suggestion.

v6: No Change

v7: No Change

v8: No Change

v9: No Change

Subject: drm/i915/icl: Enable Plane Input CSC for YUV to RGB Conversion

Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.

This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.

This has been verified and tested by Maarten and the change is working
as expecpted.

v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.

v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.

v4: Added support for Limited Range Color Handling

v5: Fixed Matt and Maarten's review comments.

v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.

v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.

v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.

v9: Fixed Ville's review comments.

Subject: drm/i915: Break long iterations for get/put shmemfs pages

As we may have to iterate a few thousand elements to acquire and release
the shmemfs backing storage for a GPU object, we need to break up the
long loop with cond_resched() to retain a modicum of low latency for
other processes.

Subject: drm/i915: Don't oops during modeset shutdown after lpe audio deinit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

Subject: drm/i915: Don't apply the 16Gb DIMM wm latency w/a to BXT/GLK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.

This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

v2: Do the check when populating is_16gb_dimm (Mahesh)

Subject: drm/i915: Compare user's 64b GTT offset even on 32b

Beware mixing unsigned long constants and 64b values, as on 32b the
constant will be zero extended and discard the high 32b when used as
a mask!

Subject: drm/i915/glk: Remove 99% limitation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.

So I got the confirmation from HW architect that we actually
never needed this workaround.

"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."

So, this reverts commit 97f55ca5b662 ("drm/i915/glk: limit pixel
 clock to 99% of cdclk workaround")

Fixes: 97f55ca5b662 ("drm/i915/glk: limit pixel clock to 99% of cdclk workaround")

Subject: drm/i915: Don't oops during modeset shutdown after lpe audio deinit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

Subject: drm/sun4i: tcon: fix check of tcon->panel null pointer

Since tcon->panel is a pointer returned by of_drm_find_panel() need to
check if it is not NULL, hence a valid pointer.
IS_ERR() instead checks return error values, not NULL pointers.

Substitute "if (!IS_ERR(tcon->panel))" with "if (tcon->panel)".

Subject: drm/i915: Fix ilk+ watermarks when disabling pipes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).

This seems to have been broken by commit b6b178a77210 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.

Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

Subject: drm/amd: Don't fail on backlight = 0

Amgpu's backlight update status function was
returning 1 (an error value) when the backlight
property was 0.  This breaks users that assume
0 is a valid backlight value (which is a
correct assumption)

If the user passes in a backlight value of 0,
tell them everything is fine, then write a value of
1 to hardware.

Subject: drm/amd/display: Stop leaking planes

[Why]
drm_plane_cleanup does not free the plane.

[How]
Call drm_primary_helper_destroy which will also free the plane.

Subject: Revert "drm/amd/display: set backlight level limit to 1"

This reverts commit 0cafc82fae41531b0162150f9a97f2c74f97118f.

This breaks some apps that assume 0 is minimum brightness.

Revert for 4.20.  This is fixed properly for drm-next/4.21 in:
"drm/amd: Don't fail on backlight = 0"
However, that patch depends on more extensive changes to the
backlight interface which are too invasive for -fixes.

Fix it to print hexadecimal, as was intended.

Subject: mm, drm/i915: mark pinned shmemfs pages as unevictable

The i915 driver uses shmemfs to allocate backing storage for gem
objects. These shmemfs pages can be pinned (increased ref count) by
shmem_read_mapping_page_gfp(). When a lot of pages are pinned, vmscan
wastes a lot of time scanning these pinned pages. In some extreme case,
all pages in the inactive anon lru are pinned, and only the inactive
anon lru is scanned due to inactive_ratio, the system cannot swap and
invokes the oom-killer. Mark these pinned pages as unevictable to speed
up vmscan.

Export pagevec API check_move_unevictable_pages().

This patch was inspired by Chris Wilson's change [1].

controls or even the current on), it was discovered that we merely
needed to delay the EMIT_INVALIDATE by several flushes. It is important
to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that
needs the delay as opposed to what one might first expect -- that the
delay is required for the TLB invalidation to take effect (one presumes
to purge any CS buffers) as opposed to a delay after flushing to ensure
the writes have landed before triggering invalidation.

Content-Transfer-Encoding: 8bit

No need for the posting reads in the plane update/disable hooks.
If we need a posting read for something then a single one at the
very end would be sufficient. We have that anyway in the form
of eg. scanline/frame counter reads.

This hasn't caused any issues yet that I'm aware of, but as Ville
Syrjälä pointed out - we need to make sure that
intel_connector->mst_port is set before initializing MST connectors,
since in theory we could potentially check intel_connector->mst_port in
i915_hpd_poll_init_work() after registering the connector but before
having written it's value.

This appears to be due to the fact that with an MST topology, not all
intel_connector structs will have ->encoder set. So, fix this by
skipping connectors without encoders in
intel_hpd_irq_storm_reenable_work().

For those wondering, this bug was found on accident while simulating HPD
storms using a Chamelium connected to a ThinkPad T450s (Broadwell).

Changes since v1:
- Check intel_connector->mst_port instead of intel_connector->encoder

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

Currently in intel_hpd_irq_storm_detect() when we detect that the last
recorded hotplug wasn't within the period defined by
HPD_STORM_DETECT_DELAY, we make the mistake of resetting the HPD count
to 0 without incrementing it. This results in us only enabling storm
detection when we go +2 above the threshold, e.g. an HPD threshold of 5
would not trigger a storm until we reach a total of 7 hotplugs.

So: rework the code a bit so we reset the HPD count when
HPD_STORM_DETECT_DELAY has passed, then increment the count afterwards.
Also, clean things up a bit to make it easier to undertand.

This is rather confusing to look at as-is:
dev_priv->display.hpd_irq_setup(dev_priv); in intel_hpd_irq_handler()
handles disabling the actual HPD IRQ, while
intel_hpd_irq_storm_disable() handles moving the HPD pin state over from
MARK_DISABLED to DISABLED along with enabling polling for it.

Subject: drm/i915: Add short HPD IRQ storm detection for non-MST systems
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unfortunately, it seems that the HPD IRQ storm problem from the early
days of Intel GPUs was never entirely solved, only mostly. Within the
last couple of days, I got a bug report from one of our customers who
had been having issues with their machine suddenly booting up very
slowly after having updated. The amount of time it took to boot went
from around 30 seconds, to over 6 minutes consistently.

After some investigation, I discovered that i915 was reporting massive
amounts of short HPD IRQ spam on this system from the DisplayPort port,
despite there not being anything actually connected. The symptoms would
start with one "long" HPD IRQ being detected at boot:

[    1.891398] [drm:intel_get_hpd_pins [i915]] hotplug event received, stat 0x00440000, dig 0x00440000, pins 0x000000a0

The customer's system in question has a GM45 GPU, which is apparently
well known for hotplugging storms.

So, workaround this impressively broken hardware by changing the default
HPD storm threshold from 5 to 50. Then, make long IRQs count for 10, and
short IRQs count for 1. This makes it so that 5 long IRQs will trigger
an HPD storm, and on systems with short HPD storm detection 50 short
IRQs will trigger an HPD storm. 50 short IRQs amounts to 100ms of
constant pulsing, which seems like a good middleground between being too
sensitive and not being sensitive enough (which would cause visible
stutters in userspace every time a storm occurs).

And just to be extra safe: we don't enable this by default on systems
with MST support. There's too high of a chance of MST support triggering
storm detection, and systems that are new enough to support MST are a
lot less likely to have issues with IRQ storms anyway.

As a note: this patch was tested using a ThinkPad T450s and a Chamelium
to simulate the short IRQ storms.

Changes since v1:
- Don't use two separate thresholds, just make long IRQs count for 10
  each and short IRQs count for 1. This simplifies the code a bit
  - Ville Syrjälä
Changes since v2:
- Document @long_hpd in intel_hpd_irq_storm_detect, no functional
  changes
Changes since v4:
- Remove !! in long_hpd assignment - Ville Syrjälä
- queue_hp = true - Ville Syrjälä

Subject: drm/amd/display: Drop reusing drm connector for MST

[why]
It is not safe to keep existing connector while entire topology
has been removed. Could lead potential impact to uapi.
Entirely unregister all the connectors on the topology,
and use a new set of connectors when the topology is plugged back
on.

[How]
Remove the drm connector entirely each time when the
corresponding MST topology is gone.
When hotunplug a connector (e.g., DP2)
1. Remove connector from userspace.
2. Drop it's reference.
When hotplug back on:
1. Detect new topology, and create new connectors.
2. Notify userspace with sysfs hotplug event.
3. Reprobe new connectors, and reassign CRTC from old (e.g., DP2)
to new (e.g., DP3) connector.

Subject: drm/amd/amdgpu/dm: Fix dm_dp_create_fake_mst_encoder()

[why]
Removing connector reusage from DM to match the rest of the tree ended
up revealing an issue that was surprisingly subtle. The original amdgpu
code for DC that was submitted appears to have left a chunk in
dm_dp_create_fake_mst_encoder() that tries to find a "master encoder",
the likes of which isn't actually used or stored anywhere. It does so at
the wrong time as well by trying to access parts of the drm_connector
from the encoder init before it's actually been initialized. This
results in a NULL pointer deref on MST hotplugs:

Somehow the connector reusage DM was using for MST connectors managed to
paper over this issue entirely; hence why this was never caught until
now.

[how]
Since this code isn't used anywhere and seems useless anyway, we can
just drop it entirely. This appears to fix the issue on my HP ZBook with
an AMD WX4150.

Currently, SDMA page queue is not used under SR-IOV VF, and this queue will
cause ring test failure in amdgpu module reload case. So just disable it.

[why]
It is not correct to touch aconnector within atomic_check.

[How]
It was added as workaround before, and no longer needed.

Subject: drm/amd/display: Drop reusing drm connector for MST

[why]
It is not safe to keep existing connector while entire topology
has been removed. Could lead potential impact to uapi.
Entirely unregister all the connectors on the topology,
and use a new set of connectors when the topology is plugged back
on.

[How]
Remove the drm connector entirely each time when the
corresponding MST topology is gone.
When hotunplug a connector (e.g., DP2)
1. Remove connector from userspace.
2. Drop it's reference.
When hotplug back on:
1. Detect new topology, and create new connectors.
2. Notify userspace with sysfs hotplug event.
3. Reprobe new connectors, and reassign CRTC from old (e.g., DP2)
to new (e.g., DP3) connector.

Subject: drm/amd/amdgpu/dm: Fix dm_dp_create_fake_mst_encoder()

[why]
Removing connector reusage from DM to match the rest of the tree ended
up revealing an issue that was surprisingly subtle. The original amdgpu
code for DC that was submitted appears to have left a chunk in
dm_dp_create_fake_mst_encoder() that tries to find a "master encoder",
the likes of which isn't actually used or stored anywhere. It does so at
the wrong time as well by trying to access parts of the drm_connector
from the encoder init before it's actually been initialized. This
results in a NULL pointer deref on MST hotplugs:

Somehow the connector reusage DM was using for MST connectors managed to
paper over this issue entirely; hence why this was never caught until
now.

[how]
Since this code isn't used anywhere and seems useless anyway, we can
just drop it entirely. This appears to fix the issue on my HP ZBook with
an AMD WX4150.

Subject: drm/i915/execlists: Force write serialisation into context image vs
 execution

Ensure that the writes into the context image are completed prior to the
register mmio to trigger execution. Although previously we were assured
by the SDM that all writes are flushed before an uncached memory
transaction (our mmio write to submit the context to HW for execution),
we have empirical evidence to believe that this is not actually the
case.

Subject: drm/i915/icl: Fix combo PHY uninit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BSpec says to clear the comp init HW flag too during combo PHY uninit,
so do that. The lack of this could badly interact with the PHY reinit
after a DC6/9 transition at least, where (after a follow-up patch fixing
the init code) we'd skip the initialization incorrectly due to this flag
being set.

Subject: drm/i915/cnl+: Move the combo PHY init/uninit code to a new file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Similarly to the GEN9_LP DPIO PHY code keep the CNL+ combo PHY code in a
separate file.

No functional change.

v2:
- Use SPDX license tag instead of boilerplate. (Rodrigo)
v3:
- Use MIT instead of GPL-2.0 license. (Ville)

Subject: drm/i915/icl: Skip init for an already enabled combo PHY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bspec says we should skip the initialization of combo PHYs that are
already initialized. We'll need to reinit the PHYs more frequently
when exiting from DC6 (after the next patch), so let's make sure the
uninit sequence complies with the spec. For safety skip the init only if
all the PHY register fields have their expected values.

v2:
- Print 'Port X' as we do elsewhere instead of 'Port-X'. (Jose)

Subject: drm/i915/icl: Fix port B combo PHY context loss after DC transitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On ICL DMC/PCODE retains the HW context only for port A across DC
transitions, for the other port B combo PHY, it doesn't. So we need to
do this manually after exiting from DC6. Do the reinit even after
exiting from DC5, it won't hurt since we only reinit the PHY in case
it's needed (in case it was disabled to begin with).

As can be guessed from the bugzilla report leaving the PHY uninited will
lead to a later timeout during the port B specific AUX and DDI_IO power
well enabling.

v2:
- Apply the fix on all GEN>=11 platforms. (Rodrigo)

Subject: drm/i915: remove padding from struct skl_wm_level

This reduces the size of struct skl_wm_level from 6 to 4, which
reduces the size of struct skl_plane_wm from 104 to 70, which reduces
the size of struct skl_pipe_wm from 524 to 356. A reduction of 168
padding bytes per pipe. This will increase even more the next time we
bump I915_MAX_PLANES.

v2: Paste the pahole output provided by Lucas:

$ pahole -s -C skl_wm_level drivers/gpu/drm/i915/i915.o
struct skl_wm_level {
        bool                       plane_en;             /*     0     1 */

Although FBC helps save power it do not belongs to power management
also the cleanup was placed in i915_driver_unload() also not a good
place. intel_modeset_init()/intel_modeset_cleanup() are better places
also this will help make easy disable features that depends in
display being enabled in driver.

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

Check for reserved register field values and conflicting
transcoder->port mappings (both MST and non-MST mappings or multiple SST
mappings).

This is also needed for the next patch to determine if a port is in MST
mode during sanitization after HW readout.

Subject: drm/i915/icl: Fix PLL mapping sanitization for DP ports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We shouldn't consider an encoder inactive if it doesn't have a CRTC
linked, but has virtual MST encoders with a crtc linked. Fix this.

Also we should not sanitize the mapping for MST encoders, as it's always
their primary encoder (which could be even in SST mode) whose active
state determines if we need the clock being enabled for the
corresponding physical port. Fix this too.

This fixes at least an existing breakage where we incorrectly disabled
the clock for an active DP encoder when sanitizing its MST virtual
encoders. Not sure if there are BIOSes that enable an output in MST
mode, but our HW readout is mostly missing for it anyway, so just warn
for that case.

Subject: drm/i915: Fix hpd handling for pins with two encoders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In my haste to remove irq_port[] I accidentally changed the
way we deal with hpd pins that are shared by multiple encoders
(DP and HDMI for pre-DDI platforms). Previously we would only
handle such pins via ->hpd_pulse(), but now we queue up the
hotplug work for the HDMI encoder directly. Worse yet, we now
count each hpd twice and this increment the hpd storm count
twice as fast. This can lead to spurious storms being detected.

Go back to the old way of doing things, ie. delegate to
->hpd_pulse() for any pin which has an encoder with that hook
implemented. I don't really like the idea of adding irq_port[]
back so let's loop through the encoders first to check if we
have an encoder with ->hpd_pulse() for the pin, and then go
through all the pins and decided on the correct course of action
based on the earlier findings.

I have occasionally toyed with the idea of unifying the pre-DDI
HDMI and DP encoders into a single encoder as well. Besides the
hotplug processing it would have the other benefit of preventing
userspace from trying to enable both encoders at the same time.
That is simply illegal as they share the same clock/data pins.
We have some testcases that will attempt that and thus fail on
many older machines. But for now let's stick to fixing just the
hotplug code.

Subject: drm/i915: Sanitize PCH port transcoder select on IBX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

IBX has a documented workaround which states that when we disable the
port we must change its transcoder select to A, otherwise it will
prevent the other port (DP vs. HDMI/SDVO) from using transcoder A.
We implement the workaround during encoder disable, but looks like
some BIOSen leave transcoder B selected even when the port wasn't
actually enabled by the BIOS. That will trip up our asserts
that attempt to make sure we never forget this w/a.

Sanitize the transcoder select to A for all disabled PCH
DP/HDMI/SDVO ports. We assume that the port was never enabled
by the BIOS on transcoder B, because if it had we'd actually have
to toggle the port on and back off to properly switch it back to
transcoder A. That would cause some display flicker if transcoder A
is already enabled on some other port, so it's better not to do it
unless absolutely necessary. Since we have no indication that the
transcoder select is misbehaving on the affected machines we can
assume the port was never actually enabled by the BIOS.

This cures warning like this during driver load:
IBX PCH DP C still using transcoder B

On skl+ the scaler (when enabled) will take care of the plane output
position. Make the code less ugly by just setting crtc_x/y to 0
when the scaler is enabled.

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

Make skl_ddb_allocation_overlaps() useful for other callers
besides skl_update_crtcs(). We'll need it to do plane updates
as well.

And while we're here we can reduce the stack utilization a
bit by noting that each struct skl_ddb_entry is 4 bytes whereas
a pointer to one is 8 bytes (on 64bit). So we'll switch to an
array of structs from the array of pointers we used before.

Subject: drm/dp_mst: Check if primary mstb is null

Unfortunately drm_dp_get_mst_branch_device which is called from both
drm_dp_mst_handle_down_rep and drm_dp_mst_handle_up_rep seem to rely
on that mgr->mst_primary is not NULL, which seem to be wrong as it can be
cleared with simultaneous mode set, if probing fails or in other case.
mgr->lock mutex doesn't protect against that as it might just get
assigned to NULL right before, not simultaneously.

There are currently bugs 107738, 108616 bugs which crash in
drm_dp_get_mst_branch_device, caused by this issue.

v2: Refactored the code, as it was nicely noticed.
    Fixed Bugzilla bug numbers(second was 108616, but not 108816)
    and added links.

Both functions have the same code to disable PSR, so let's reuse that
code instead of duplicate.

Subject: drm/i915/psr: Always wait for idle state when disabling PSR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It should always wait for idle state when disabling PSR because PSR
could be inactive due a call to intel_psr_exit() and while PSR is
still being disabled asynchronously userspace could change the
modeset causing a call to psr_disable() that will not wait for PSR
idle and then PSR will be enabled again while PSR is still not idle.

v2: rebased on top of the patch reusing psr_exit()

In the past we had hooks to configure HW for VLV/CHV too, in the drop

to the caller, so doing it here.

Subject: drm/omap: Populate DSS children in omapdss driver

The DSS DT node contains children that describe the DSS components
(DISPC and internal encoders). Each of those components is handled by a
platform driver, and thus needs to be backed by a platform device.

The corresponding platform devices are created in mach-omap2 code by a
call to of_platform_populate(). While this approach has worked so far,
it doesn't model the hardware architecture very well, as it creates
child devices before the parent is ready to handle them. This would be
akin to creating I2C slaves before the I2C master is available.

The task can be easily performed in the omapdss driver code instead,
simplifying mach-omap2 code. We however can't remove the mach-omap2 code
completely as the omap2fb driver still depends on it, but we can move it
to the omap2fb-specific section, where it can stay until the omap2fb
driver gets removed.

This has the added benefit of not allowing DSS components to probe
before the DSS itself, which led to runtime PM issues when the DSS probe
is deferred.

Subject: drm/omap: Move DISPC runtime PM handling to omapdrm

The internal encoders (DSI, HDMI4, HDMI5 and VENC) runtime PM handlers
attempt to manage the runtime PM state of the connected DISPC, based on
the rationale that the DISPC providing data to the encoders requires
ensuring that the display is active whenever the encoders are active.

While the DISPC provides data to the encoders, it doesn't as such
constitute a resource that encoders require in order to be taken out
of suspend, contrary to for instance a functional clock or a power
supply. Encoders registers can be accessed without the DISPC being
active, and while the encoders will not output any video stream without
being fed by the DISPC, the DISPC PM state doesn't influence the
encoders PM state.

For this reason the DISPC PM state is better managed from the omapdrm
driver, in the CRTC enable and disable operations. This allows the
encoders PM state to be handled separately from the DISPC, and in
particular at times when the DISPC may not be available (for instance at
probe due to the DSS probe being deferred, or at remove time du to the
DISPC being already removed).

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

ironlake_check_fdi_lanes() may try to grab some extra crtc locks.
If that fails we need to propagate the -EDEADLK all the way up,
and we shouldn't dump out the crtc state or other debug messages
either since it wasn't the crtc state that caused the failure.

Just hit this on my IVB:

Pass on the errno all the way from connected_sink_max_bpp(),
and make the base_bpp handling in intel_modeset_pipe_config()
a bit less ugly. We'll also rename connected_sink_max_bpp()
to not give the impression that it return the bpp value,
and we'll pimp up the debug message within to include the
connector name/id.

Subject: drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Exercising the gpu reloc path strenuously revealed an issue where the
updated relocations (from MI_STORE_DWORD_IMM) were not being observed
upon execution. After some experiments with adding pipecontrols (a lot
of pipecontrols (32) as gen4/5 do not have a bit to wait on earlier pipe
controls or even the current on), it was discovered that we merely
needed to delay the EMIT_INVALIDATE by several flushes. It is important
to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that
needs the delay as opposed to what one might first expect -- that the
delay is required for the TLB invalidation to take effect (one presumes
to purge any CS buffers) as opposed to a delay after flushing to ensure
the writes have landed before triggering invalidation.

This hasn't caused any issues yet that I'm aware of, but as Ville
Syrjälä pointed out - we need to make sure that
intel_connector->mst_port is set before initializing MST connectors,
since in theory we could potentially check intel_connector->mst_port in
i915_hpd_poll_init_work() after registering the connector but before
having written it's value.

Turns out that if you trigger an HPD storm on a system that has an MST
topology connected to it, you'll end up causing the kernel to eventually
hit a NULL deref:

This appears to be due to the fact that with an MST topology, not all
intel_connector structs will have ->encoder set. So, fix this by
skipping connectors without encoders in
intel_hpd_irq_storm_reenable_work().

For those wondering, this bug was found on accident while simulating HPD
storms using a Chamelium connected to a ThinkPad T450s (Broadwell).

Changes since v1:
- Check intel_connector->mst_port instead of intel_connector->encoder

Subject: drm/i915/execlists: Force write serialisation into context image vs
 execution

Ensure that the writes into the context image are completed prior to the
register mmio to trigger execution. Although previously we were assured
by the SDM that all writes are flushed before an uncached memory
transaction (our mmio write to submit the context to HW for execution),
we have empirical evidence to believe that this is not actually the
case.

Subject: drm/i915: Fix hpd handling for pins with two encoders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In my haste to remove irq_port[] I accidentally changed the
way we deal with hpd pins that are shared by multiple encoders
(DP and HDMI for pre-DDI platforms). Previously we would only
handle such pins via ->hpd_pulse(), but now we queue up the
hotplug work for the HDMI encoder directly. Worse yet, we now
count each hpd twice and this increment the hpd storm count
twice as fast. This can lead to spurious storms being detected.

Go back to the old way of doing things, ie. delegate to
->hpd_pulse() for any pin which has an encoder with that hook
implemented. I don't really like the idea of adding irq_port[]
back so let's loop through the encoders first to check if we
have an encoder with ->hpd_pulse() for the pin, and then go
through all the pins and decided on the correct course of action
based on the earlier findings.

I have occasionally toyed with the idea of unifying the pre-DDI
HDMI and DP encoders into a single encoder as well. Besides the
hotplug processing it would have the other benefit of preventing
userspace from trying to enable both encoders at the same time.
That is simply illegal as they share the same clock/data pins.
We have some testcases that will attempt that and thus fail on
many older machines. But for now let's stick to fixing just the
hotplug code.

Subject: drm/amdgpu: refactor smu8_send_msg_to_smc and WARN_ON time out

This patch refactors smu8_send_msg_to_smc_with_parameter() to include
smu8_send_msg_to_smc_async() so that all the messages sent to SMU can be
profiled and appropriately reported if they fail.

Subject: drm/i915: Switch LSPCON to PCON mode if it's in LS mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We no longer change LSPCON into PCON mode if it boots up in
LS mode. This was broken by some code shuffling in
commit 96e35598cead ("drm/i915: Check LSPCON vendor OUI").

I actually can't see a reason why that code shuffling had
to be done. The commit msg notes it but doesn't justify it
in any way. But I guess we'll keep the code in its current
place anyway and just make the "switch to PCON mode" part
effective once again.

The bug limits the IH ring wptr address to 40bit. When the system memory

interrupt cannot be handled and cleared correctly.

Subject: drm/i915: Always write both TILEOFF and LINOFF plane registers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reduce the clutter in the sprite update functions by writing
both TILEOFF and LINOFF registers unconditionally. We already
did this for primary planes so might as well do it for the
sprites too.

There is no harm in writing both registers. Which one gets
used depends on the tilimg mode selected in the plane control
registers.

It might even make sense to clear the register that won't
get used. That could make register dumps a little easier to
parse. But I'm not sure it's worth the extra hassle.

Subject: drm/i915: Account for scale factor when calculating initial phase
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To get the initial phase correct we need to account for the scale
factor as well. I forgot this initially and was mostly looking at
heavily upscaled content where the minor difference between -0.5
and the proper initial phase was not readily apparent.

And let's toss in a comment that tries to explain the formula
a little bit.

v2: The initial phase upper limit is 1.5, not 24.0!

No point in cluttering the common codepaths with the

ilk_compute_intermediate_wm() as those are the only
platforms using this.

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

Let's make sure the DSI port is actually on before we go
poking at the plane register to determine which way
it's rotated. Otherwise we could be looking at a plane
that is feeding a HDMI port for instance.

And in order to read the plane register we need the power
well to be on. Make sure that is indeed the case. We'll
also make sure the plane is actually enabled before we
trust the rotation bit to tell us the truth.

Subject: drm/i915: Determine DSI panel orientation from VBT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VBT appears to have two (or possibly three) ways to indicate the panel
rotation. The first is in the MIPI config block, but that apparenly
usually (maybe always?) indicates 0 degrees despite the actual panel
orientation. The second way to indicate this is in the general features
block, which can just indicate whether 180 degress rotation is used.
The third might be a separate rotation data block, but that is not
at all documented so who knows what it may contain.

Let's try the first two. We first try the DSI specicic VBT
information, and it it doesn't look trustworthy (ie. indicates
0 degrees) we fall back to the 180 degree thing. Just to avoid too
many changes in one go we shall also keep the hardware readout path
for now.

If this works for more than just my VLV FFRD the question becomes
how many of the panel orientation quirks are now redundant?

v2: Move the code into intel_dsi.c (Jani)

the clk value should be tranferred to MHz first and

BSpec was updated and now there's no more "subtract 1" to the

It seems this should help fixing some GMBUS issues. I'm not aware of
any specific open bug that could be solved by this patch.

Subject: drm/i915: rename CNP_RAWCLK_FRAC to CNP_RAWCLK_DEN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Although CNP names this field "Counter Fraction", what we write to the
register is really the denominator for the fractional part of the
divider, not the fractional part (and the field description even says
that). The ICP spec renamed the field to "Counter Fraction
Denominator", which makes a lot more sense. Use the more complete ICL
naming because we will merge the CNP and ICP functions into a single
one, which will introduce the concept of the numerator. That will make
a lot more sense when you read the "num/frac = den" calculation.

Subject: drm/i915: add ICP support to cnp_rawclk() and kill icp_rawclk()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I think I'm probably the one who argued in favor of having separate
implementations for both PCHs, but the calculations are actually the
same, the clocks are the same and the only difference is that on ICP
we write the numerator to the register.

I have previously suggested to kill cnp_rawclk() and keep the
icp_rawclk() style, but Ville gave some good arguments that what's in
this patch may be the better choice.

v2: Switch numerator to 1 from 1000 and adjust calculations
    accordingly (Ville).

Subject: drm/i915/gen9_bc: Work around DMC bug zeroing power well requests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A DMC bug on GEN9 big core machines fails to restore the driver's
request bits for the PW1 and MISC_IO power wells after a DC5/6
entry->exit sequence. As a consequence the driver's subsequent check for
the enabled status of these power wells will fail, as the check
considers the power wells being enabled only if both the status and
request bits are set. To work around this borrow the request bits from
BIOS's own request register in which DMC forces on the request bits when
exiting from DC5/6.

This fixes a problem reported by Ramalingam, where HDCP init failed,
since PW1 reported itself as being disabled, while in reality it was
enabled.

Subject: drm/i915: Remove special case for power well 1/MISC_IO state
 verification
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Even though PW#1 and the MISC_IO power wells are managed by the
DMC firmware (toggled dynamically if conditions allow it) from the
driver's POV they are always on if the display core is initialized
(always restored by DMC to the enabled state after exiting from DC5/6
for instance b/c of MMIO access). Accordingly we can just mark them as
always-on and remove the special casing for them during state
verification (thus enabling verification for these power wells too).

Subject: drm/i915: Fix plane allocation/free functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use intel_plane_destroy_state in intel_plane_free to free the state.
Also fix intel_plane_alloc() to use __drm_atomic_helper_plane_reset(),
to get sane defaults from the atomic core.

This is needed to get the correct alpha value and blend mode from the
core, and any new default values added from new properties.

Subject: drm/i915: remove excess line continuation backslashes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While removing .palette_offsets, I removed the commas after
.trans_offsets in the macros, but failed to remove the line continuation
backslashes.

While at it, also remove another extra comma to be in line with the
other related macros.

Fixes: 74c1e826427a ("drm/i915: remove palette_offsets from device info in favor of _PICK()")

Subject: drm/i915: Account for scale factor when calculating initial phase
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To get the initial phase correct we need to account for the scale
factor as well. I forgot this initially and was mostly looking at
heavily upscaled content where the minor difference between -0.5
and the proper initial phase was not readily apparent.

And let's toss in a comment that tries to explain the formula
a little bit.

v2: The initial phase upper limit is 1.5, not 24.0!

Subject: drm/vc4: Fix NULL pointer dereference in the async update path

vc4_plane_atomic_async_update() calls vc4_plane_atomic_check()
which in turn calls vc4_plane_setup_clipping_and_scaling(), and since
commit 58a6a36fe8e0 ("drm/vc4: Use
drm_atomic_helper_check_plane_state() to simplify the logic"), this
function accesses plane_state->state which will be NULL when called
from the async update path because we're passing the current plane
state, and plane_state->state has been assigned to NULL in
drm_atomic_helper_swap_state().

Pass the new state instead of the current one (the new state has
->state set to a non-NULL value).

Fixes: 58a6a36fe8e0 ("drm/vc4: Use drm_atomic_helper_check_plane_state() to simplify the logic")

Subject: drm/vc4: Set ->legacy_cursor_update to false when doing non-async
 updates

drm_atomic_helper_setup_commit() auto-completes commit->flip_done when
state->legacy_cursor_update is true, but we know for sure that we want
a sync update when we call drm_atomic_helper_setup_commit() from
vc4_atomic_commit().

Explicitly set state->legacy_cursor_update to false to prevent this
auto-completion.

Subject: drm/amdgpu: Add amdgpu "max bpc" connector property (v2)

[Why]
Many panels support more than 8bpc but some modes are unavailable while
running at greater than 8bpc due to DP/HDMI bandwidth constraints.

Support for more than 8bpc was added recently in the driver but it
defaults to the maximum supported bpc - locking out these modes.

This should be a user configurable option such that the user can select
what bpc configuration they would like.

[How]
This patch introduces the "max bpc" amdgpu driver specific connector
property so the user can limit the maximum bpc. It ranges from 8 to 16.

This doesn't directly set the preferred bpc for the panel since it
follows Intel's existing driver conventions.

This proprety should be removed once common drm support for max bpc
lands.

v2: rebase on upstream (Alex)

defaults to the maximum supported bpc - locking out these modes.

This should be a user configurable option such that the user can select
what bpc configuration they would like.

[How]
This patch adds support for getting and setting the amdgpu driver
specific "max bpc" property on the connector.

It also adds support for limiting the output bpc based on the property
value. The default limitation is the lowest value in the range, 8bpc.
This was the old value before the range was uncapped.

This patch should be updated/replaced later once common drm support
for max bpc lands.

lockdep insists that if we give a lock a subclass, it must be used.
Failure to do so triggers a self-consistency check when reading

Subject: drm/i915: Disable LP3 watermarks on all SNB machines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I have a Thinkpad X220 Tablet in my hands that is losing vblank
interrupts whenever LP3 watermarks are used.

If I nudge the latency value written to the WM3 register just
by one in either direction the problem disappears. That to me
suggests that the punit will not enter the corrsponding
powersave mode (MPLL shutdown IIRC) unless the latency value
in the register matches exactly what we read from SSKPD. Ie.
it's not really a latency value but rather just a cookie
by which the punit can identify the desired power saving state.
On HSW/BDW this was changed such that we actually just write
the WM level number into those bits, which makes much more
sense given the observed behaviour.

We could try to handle this by disallowing LP3 watermarks
only when vblank interrupts are enabled but we'd first have
to prove that only vblank interrupts are affected, which
seems unlikely. Also we can't grab the wm mutex from the
vblank enable/disable hooks because those are called with
various spinlocks held. Thus we'd have to redesigne the
watermark locking. So to play it safe and keep the code
simple we simply disable LP3 watermarks on all SNB machines.

To do that we simply zero out the latency values for
watermark level 3, and we adjust the watermark computation
to check for that. The behaviour now matches that of the
g4x/vlv/skl wm code in the presence of a zeroed latency
value.

v2: s/USHRT_MAX/U32_MAX/ for consistency with the types (Chris)

Subject: drm/ast: Remove existing framebuffers before loading driver

If vesafb attaches to the AST device, it configures the framebuffer memory
for uncached access by default. When ast.ko later tries to attach itself to
the device, it wants to use write-combining on the framebuffer memory, but
vesefb's existing configuration for uncached access takes precedence. This
results in reduced performance.

Removing the framebuffer's configuration before loding the AST driver fixes
the problem. Other DRM drivers already contain equivalent code.

Subject: drm/i915: Disable LP3 watermarks on all SNB machines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I have a Thinkpad X220 Tablet in my hands that is losing vblank
interrupts whenever LP3 watermarks are used.

If I nudge the latency value written to the WM3 register just
by one in either direction the problem disappears. That to me
suggests that the punit will not enter the corrsponding
powersave mode (MPLL shutdown IIRC) unless the latency value
in the register matches exactly what we read from SSKPD. Ie.
it's not really a latency value but rather just a cookie
by which the punit can identify the desired power saving state.
On HSW/BDW this was changed such that we actually just write
the WM level number into those bits, which makes much more
sense given the observed behaviour.

We could try to handle this by disallowing LP3 watermarks
only when vblank interrupts are enabled but we'd first have
to prove that only vblank interrupts are affected, which
seems unlikely. Also we can't grab the wm mutex from the
vblank enable/disable hooks because those are called with
various spinlocks held. Thus we'd have to redesigne the
watermark locking. So to play it safe and keep the code
simple we simply disable LP3 watermarks on all SNB machines.

To do that we simply zero out the latency values for
watermark level 3, and we adjust the watermark computation
to check for that. The behaviour now matches that of the
g4x/vlv/skl wm code in the presence of a zeroed latency
value.

v2: s/USHRT_MAX/U32_MAX/ for consistency with the types (Chris)

Subject: drm/i915: Prevent machine hang from Broxton's vtd w/a and error
 capture

Since capturing the error state requires fiddling around with the GGTT
to read arbitrary buffers and is itself run under stop_machine(), it
deadlocks the machine (effectively a hard hang) when run in conjunction
with Broxton's VTd workaround to serialize GGTT access.

v2: Store the ERR_PTR in first_error so that the error can be reported
to the user via sysfs.
v3: Mention the quirk in dmesg (using info as per usual)

Subject: drm/amd/pp: handle negative values when reading OD

Reading the sysfs files pp_sclk_od and pp_mclk_od return the
percentage difference between the VBIOS-provided default
frequency and the current (possibly user-set) frequency in
the highest SCLK and MCLK DPM states, respectively.

Writing to these files provides an easy mechanism for
setting a higher-than-default maximum frequency. We
normally only allow values >= 0 to be written here.

However, with the addition of pp_od_clk_voltage, we now
allow users to set custom DPM tables. If they then set
the maximum DPM state to something less than the default,
later reads of pp_*_od should return a negative value.
The highest DPM state is now less than the VBIOS-provided
default, so the percentage is negative.

The math to calculate this was originally performed with
unsigned values, meaning reads that should return negative
values returned meaningless data. This patch corrects that
issue and normalizes how all of the calculations are done
across the various hwmgr types.

Subject: drm/i915: Prevent machine hang from Broxton's vtd w/a and error
 capture

Since capturing the error state requires fiddling around with the GGTT
to read arbitrary buffers and is itself run under stop_machine(), it
deadlocks the machine (effectively a hard hang) when run in conjunction
with Broxton's VTd workaround to serialize GGTT access.

v2: Store the ERR_PTR in first_error so that the error can be reported
to the user via sysfs.
v3: Mention the quirk in dmesg (using info as per usual)

Subject: drm/i915: Write GPU relocs harder with gen3

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

When there is no output no one will hold a runtime_pm reference
causing a warning when trying to read emom_status in debugfs.

Subject: drm/i915: allow to load DMC firmware on next gen

Before commit d8a5b7d79fb7 ("drm/i915/csr: keep max firmware size together
with firmare name and version") it was possible to load the firmware for
testing purposes via parameter. Let's use the size of the last known
platform to recover that behavior.

Like it was done in commit 9e180d9991dc ("drm/i915: Downgrade unknown
firmware warnings") for huc and guc: downgrade CSR firmware warnings. If
we have released no firmware yet for a platform, stop scaring the
consumer and merely note its expected absence.

By simply removing the warning and early return we hit the condition
with the appropriate message.

Subject: drm/i915: Write GPU relocs harder with gen3

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

Subject: drm/fb-helper: Blacklist writeback when adding connectors to fbdev

Writeback connectors do not produce any on-screen output and require
special care for use. Such connectors are hidden from enumeration in
DRM resources by default, but they are still picked-up by fbdev.
This makes rather little sense since fbdev is not really adapted for
dealing with writeback.

Moreover, this is also a source of issues when userspace disables the
CRTC (and associated plane) without detaching the CRTC from the
connector (which is hidden by default). In this case, the connector is
still using the CRTC, leading to am "enabled/connectors mismatch" and
eventually the failure of the associated atomic commit. This situation
happens with VC4 testing under IGT GPU Tools.

Filter out writeback connectors in the fbdev helper to solve this.

MIME-Version: 1.0

Depending on the transcoder enum values to translate from transcoder
to pipe/transcoder register addresses can easily break if we add a new
transcoder. So remove the dependency by using named initializers.

Subject: drm/i915: Make EDP PSR flags not depend on enum values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Depending on the transcoder enum values to translate from transcoder
to EDP PSR flags can easily break if we add a new transcoder. So remove
the dependency by using an explicit mapping.

While at it also add a WARN for unexpected trancoders.

v2:
- Simplify things by defining flag shift values instead of indices.
- s/trans/cpu_transcoder/ (Ville)
v3:
- Define flags to look like separate bits instead of the values of
  the same bitfield. (Ville)

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

Add a comment to the pipe and transcoder enum definitions about our
assumption in the code about enum values for pipes and transcoders
with a 1:1 transcoder -> pipe mapping.

v2:
- Clarify more what are the assumptions about the enum values. (Ville)
v3: (Lucas)
- s/->/ -> / so it looks less like pointer dereferencing.
- Use pipe enums as initializers in the transcoder enum definition.

Subject: drm/i915: Make CHICKEN_TRANS reg not depend on enum value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Depending on the transcoder enum values to translate from transcoder to
the corresponding CHICKEN_TRANS register can easily break if we add a
new transcoder. Add an explicit mapping instead, by using helpers to
look up the register instance either by transcoder or port (since
unconveniently the registers have both port and transcoder specific
bits).

While at it also check for the correctness of GEN, port, transcoder. I
wasn't sure if psr2_enabled can only be set for GEN9+, but that seems to
be the case indeed (see setting of sink_psr2_support in
intel_psr_init_dpcd()).

v2 (Ville):
- Make gen9_chicken_trans_reg() internal to intel_psr.c.
- s/trans/cpu_transcoder/

Subject: drm/i915: Force a LUT update in intel_initial_commit()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.

To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Subject: drm/i915: Add rotation readout for plane initial config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If we need to force a full plane update before userspace/fbdev
have given us a proper plane state we should try to maintain the
current plane state as much as possible (apart from the parts
of the state we're trying to fix up with the plane update).
To that end add basic readout for the plane rotation and
maintain it during the initial fb takeover.

Subject: drm/i915: Force a LUT update in intel_initial_commit()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.

To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Subject: drm/shmobile: Replace drm_dev_unref with drm_dev_put

This patch unifies the naming of DRM functions for reference counting
of struct drm_device. The resulting code is more aligned with the rest
of the Linux kernel interfaces.

Subject: drm: rcar-du: Fix external clock error checks

The rcar-du driver supports probe deferral for external clocks, but
implements it badly by checking the wrong pointer due to a bad copy and
paste. Fix it.

While at it, reject invalid clocks outright for DU channels that have a
display PLL, as the external clock is mandatory in that case. This
avoids a WARN_ON() at runtime.
