022546cdbf drm/panel: nt37801: select CONFIG_DRM_DISPLAY_DSC_HELPER 
The newly added driver uses the DSC helper module, but does not
select its Kconfig symbol, so configurations are possible that
cause a link failure:

879ede5395 drm/xe: Default auto_link_downgrade status to false 
xe_pcode_read() can return back successfully without updating the
variable 'val'. This can cause an arbitrary value to show up in the
sysfs file.

Allow the auto_link_downgrade_status to default to 0 to avoid any
arbitrary value from coming up.

e22d7acf9f drm/xe/guc: Make creation of SLPC debugfs files conditional 
Platforms that do not support SLPC are exempted from the GuC PC support.
The GuC PC does not get initialized, and neither do its BOs get created.

This causes a problem because the GuC PC debugfs file is still being
created. Whenever the file is attempted to read, it causes a NULL
pointer dereference on the supposed BO of the GuC PC.

So, make the creation of SLPC debugfs files conditional to when SLPC
features are supported.

0132ba7ff0 drm/amdgpu: Fix eviction fence worker race during fd close 
The current cleanup order during file descriptor close can lead to
a race condition where the eviction fence worker attempts to access
a destroyed mutex from the user queue manager:

[  517.294055] DEBUG_LOCKS_WARN_ON(lock->magic != lock)
[  517.294060] WARNING: CPU: 8 PID: 2030 at kernel/locking/mutex.c:564
[  517.294094] Workqueue: events amdgpu_eviction_fence_suspend_worker [amdgpu]

The issue occurs because:
1. We destroy the user queue manager (including its mutex) first
2. Then try to destroy eviction fences which may have pending work
3. The eviction fence worker may try to access the already-destroyed mutex

Fix this by reordering the cleanup to:
1. First mark the fd as closing and destroy eviction fences,
   which flushes any pending work
2. Then safely destroy the user queue manager after we're certain
   no more fence work will be executed

The copy in amdgpu_driver_postclose_kms() needs to be removed (Christian)

eed6a6b226 drm/amdkfd: Change svm_range_get_info return type 
Static analysis shows that pointer "svms" cannot be NULL because it points
to the object "struct svm_range_list". Remove the extra NULL check. It is
meaningless and harms the readability of the code.

In the function svm_range_get_info() there is no possibility of failure.
Therefore, the caller of the function svm_range_get_info() does not need
a return value. Change the function svm_range_get_info() return type from
"int" to "void".

Since the function svm_range_get_info() has a return type of "void". The
caller of the function svm_range_get_info() does not need a return value.
Delete extra code.

471db2c2d4 drm/scheduler: signal scheduled fence when kill job 
When an entity from application B is killed, drm_sched_entity_kill()
removes all jobs belonging to that entity through
drm_sched_entity_kill_jobs_work(). If application A's job depends on a
scheduled fence from application B's job, and that fence is not properly
signaled during the killing process, application A's dependency cannot be
cleared.

This leads to application A hanging indefinitely while waiting for a
dependency that will never be resolved. Fix this issue by ensuring that
scheduled fences are properly signaled when an entity is killed, allowing
dependent applications to continue execution.

9cb1547891 drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read 
Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
link may get disconnected inadvertently if the SINK_COUNT_ESI and the
DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
transaction. Work around the issue by reading these registers in
separate transactions.

The issue affects MTL+ platforms and will be fixed in the DP-in adapter
firmware, however releasing that firmware fix may take some time and is
not guaranteed to be available for all systems. Based on this apply the
workaround on affected platforms.

See HSD #13013007775.

Updates for v6.16

CI:
- uprev mesa

GPU:
- ACD (Adaptive Clock Distribution) support for X1-85.  This is required
  enable the higher frequencies.
- Drop fictional `address_space_size`.  For some older devices, the address
  space size is limited to 4GB to avoid potential 64b rollover math problems
  in the fw.  For these, an `ADRENO_QUIRK_4GB_VA` quirk is added.  For
  everyone else we get the address space size from the SMMU `ias` (input
  address sizes), which is usually 48b.
- Improve robustness when GMU HFI responses time out
- Fix crash when throttling GPU immediately during boot
- Fix for rgb565_predicator on Adreno 7c3
- Remove `MODULE_FIRMWARE()`s for GPU, the GPU can load the firmware after
  probe and having partial set of fw (ie. sqe+gmu but not zap) causes problems

MDSS:
- Added SAR2130P support to MDSS driver

DPU:
- Changed to use single CTL path for flushing on DPU 5.x+
- Improved SSPP allocation code to allow sharing of SSPP between planes
- Enabled SmartDMA on SM8150, SC8180X, SC8280XP, SM8550
- Added SAR2130P support
- Disabled DSC support on MSM8937, MSM8917, MSM8953, SDM660
- Misc fixes

DP:
- Switch to use new helpers for DP Audio / HDMI codec handling
- Fixed LTTPR handling

DSI:
- Added support for SA8775P
- Added SAR2130P support

MDP4:
- Fixed LCDC / LVDS controller on

HDMI:
- Switched to use new helpers for ACR data
- Fixed old standing issue of HPD not working in some cases
