[ Upstream commit f945dd89fa8da3f662508165453dafdb4035d9d3 ]
According to pci core guidelines, pci_save_config is recommended when the
driver explicitly needs to set the pci power state. As of now xe kmd is
only doing pci_save_config while entering to s2idle/s3 state, which makes
pci core think that device driver has already applied required pci power
state. This leads to GPU remain in D0 state. To fix the issue setting
the pci power state to D3Cold.

[ Upstream commit f42c09e614f1bda96f5690be8d0bb273234febbc ]
Dumb buffers were not being freed because the GEM reference that was
acquired in gb_surface_define was not dropped like it is in the 2D case.
Dropping this ref uncovered a few additional issues with freeing the
resources associated with dirty tracking in vmw_bo_free/release.
Additionally the TTM object associated with the surface were also leaking
which meant that when the ttm_object_file was closed at process exit the
destructor unreferenced an already destroyed surface.
The solution is to remove the destructor from the vmw_user_surface
associated with the dumb_buffer and immediately unreferencing the TTM
object which his removes it from the ttm_object_file.
This also allows the early return in vmw_user_surface_base_release for the
dumb buffer case to be removed as it should no longer occur.
The chain of references now has the GEM handle(s) owning the dumb buffer.
The GEM handles have a singular GEM reference to the vmw_bo which is
dropped when all handles are closed. When the GEM reference count hits
zero the vmw_bo is freed which then unreferences the surface via
vmw_resource_release in vmw_bo_release.

[ Upstream commit 0039a3b35b10d9c15d3d26320532ab56cc566750 ]
Because sync_files are passive waiters they do not participate in
the processing of fences like the traditional vmw_fence_wait IOCTL.
If userspace exclusively uses sync_files for synchronization then
nothing in the kernel actually processes fence updates as interrupts
for fences are masked and ignored if the kernel does not indicate to the
SVGA device that there are active waiters.
This oversight results in a bug where the entire GUI can freeze waiting
on a sync_file that will never be signalled as we've masked the interrupts
to signal its completion. This bug is incredibly racy as any process which
interacts with the fencing code via the 3D stack can process the stuck
fences on behalf of the stuck process causing it to run again. Even a
simple app like eglinfo is enough to resume the stuck process. Usually
this bug is seen at a login screen like GDM because there are no other
3D apps running.
By adding a seqno waiter we re-enable interrupt based processing of the
dma_fences associated with the sync_file which is signalled as part of a
dma_fence_callback.
This has likely been broken since it was initially added to the kernel in
2017 but has gone unnoticed until mutter recently started using sync_files
heavily over the course of 2024 as part of their explicit sync support.

[ Upstream commit 3c1a467372e0c356b1d3c59f6d199ed5a6612dd1 ]
[Why & How]
When MST config is unplugged/replugged too quickly, it can potentially
result in a scenario where previous DC state has not been reset before
the HPD link detection sequence begins. In this case, driver will
disable the streams/link prior to re-enabling the link for link
training.
There is a bug in the current logic that does not account for the fact
that current_state can be released and cleared prior to swapping to a
new state (resulting in the pipe_ctx stream pointers to be cleared) in
between disabling streams.
To resolve this, cache the original streams prior to committing any
stream updates.

[ Upstream commit eba692ca3abca258b3214a6e4126afefad1822f0 ]
[Why]
Memory allocation occurs within dml21_validate() for adding phantom planes.
May cause kernel to be tainted due to usage of FP Start.
[How]
Move FP start from dml21_validate to before mode programming/mode support.
Calculations requiring floating point are all done within mode programming
or mode support.

[ Upstream commit 749b5b279e5636cdcef51e15d67b77162cca6caa ]
We have a few reports of sc7180-trogdor-pompom devices that have a
panel in them that IDs as STA 0x0004 and has the following raw EDID:
00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00
10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28
1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01
01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20
55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe
00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6
We've been unable to locate a datasheet for this panel and our partner
has not been responsive, but all Starry eDP datasheets that we can
find agree on the same timing (delay_100_500_e200) so it should be
safe to use that here instead of the super conservative timings. We'll
still go a little extra conservative and allow `hpd_absent` of 200
instead of 100 because that won't add any real-world delay in most
cases.
We'll associate the string from the EDID ("116KHD024006") with this
panel. Given that the ID is the suspicious value of 0x0004 it seems
likely that Starry doesn't always update their IDs but the string will
still work to differentiate if we ever need to in the future.

[ Upstream commit 467dce3817bd2b62ccd6fcfd7aae76f242ac907e ]
If buddy manager have more than one roots and each root have sub-block
need to be free. When drm_buddy_fini called, the first loop of
force_merge will merge and free all of the sub block of first root,
which offset is 0x0 and size is biggest(more than have of the mm size).
In subsequent force_merge rounds, if we use 0 as start and use remaining
mm size as end, the block of other roots will be skipped in
__force_merge function. It will cause the other roots can not be freed.
Solution: use roots' offset as the start could fix this issue.

This is a follow up fix for
https://patchwork.freedesktop.org/patch/msgid/20241203021929.1919730-1-oak.zeng@intel.com
The overall goal is to fail vm_bind when there is memory pressure. See more
details in the commit message of above patch. Abbove patch fixes the issue
when user pass in a vm_id parameter during gem_create. If user doesn't pass
in a vm_id during gem_create, above patch doesn't help.
This patch further reject BO eviction (which could be triggered by bo validation)
if BO is bound to the current VM. vm_bind could fail due to the eviction failure.
The BO to VM reverse mapping structure is used to determine whether BO is bound
to VM.
v2:
Move vm_bo definition from function scope to if(evict) clause (Thomas)
Further constraint the condition by adding ctx->resv (Thomas)
Add a short comment describe the change.

[ Upstream commit 9cd3f4efc870463f17f6c29114c61fb6bfcaa291 ]
After successful call to drm_suballoc_manager_init() we should
make sure to call drm_suballoc_manager_fini() as it may include
some cleanup code even if we didn't start using it for real.
As we can abort init() early due to kvzalloc() failure, we should
either explicitly call drm_suballoc_manager_fini() or, even better,
postpone drm_suballoc_manager_init() once we finish all other
preparation steps, so we can rely on fini() that will do cleanup.

GuC firmware counts received VF configuration KLVs and may start
validation of the complete VF config even if some resources where
unprovisioned in the meantime, leading to unexpected errors like:
$ echo 1 | sudo tee /sys/kernel/debug/dri/0000:00:02.0/gt0/vf1/contexts_quota

tee: '/sys/kernel/debug/dri/0000:00:02.0/gt0/vf1/ggtt_quota': Input/output error
To mitigate this problem trigger explicit VF config reset after
unprovisioning any of the critical resources (GGTT, context or
doorbell IDs) that GuC is monitoring.

The ast driver looks up supplied display modes from an internal list of
display modes supported by the VBIOS.
Do not use the crtc_-prefixed display values from struct drm_display_mode
for looking up the VBIOS mode. The fields contain raw values that the
driver programs to hardware. They are affected by display settings like
double-scan or interlace.
Instead use the regular vdisplay and hdisplay fields for lookup. As the
programmed values can now differ from the values used for lookup, set
struct drm_display_mode.crtc_vdisplay and .crtc_hdisplay from the VBIOS
mode.

The RK3588 specific implementation is currently quite limited in terms
of handling the full range of display modes supported by the connected

few of them.
Additionally, it doesn't cope well with non-integer refresh rates like
59.94, 29.97, 23.98, etc.
Make use of HDMI0 PHY PLL as a more accurate DCLK source to handle
all display modes up to 4K@60Hz.

[Why]
It's possible to generate more than 50 steps in hwss_build_fast_sequence,
for example with a 6-pipe asic where all pipes are in one MPC chain. This
overflows the block_sequence buffer and corrupts block_sequence_steps,
causing a crash.
[How]
Expand block_sequence to 100 items. A naive upper bound on the possible
number of steps for a 6-pipe asic, ignoring the potential for steps to be
mutually exclusive, is 91 with current code, therefore 100 is sufficient.

[ Upstream commit e8bffa52e0253cfd689813a620e64521256bc712 ]
[Why]
Setting link DPMS off in response to HPD disconnect creates AUX
transactions on a link that is supposed to be disconnected. This can
cause issues in some cases when the sink re-asserts HPD and expects
source to re-enable the link.
[How]
Avoid AUX transactions on disconnected link.

[ Upstream commit b40d022ec06ade9f6c809091dc188422a0f0946d ]
[why]
currently dml2 is using a hard coded 16 to convert memclk to dram_speed_mts.
for apu, this depends on wck_ratio.
change to pass the already calculated dram_speed_mts from fpu to dml2.
v2: use existing calculation of dram_speed_mts for now to avoid regression
