f903b85ed0 drm/amdgpu: fix possible fence leaks from job structure
If we don't end up initializing the fences, free them when
we free the job.  We can't set the hw_fence to NULL after
emitting it because we need it in the cleanup path for the
submit direct case.

v2: take a reference to the fences if we emit them
v3: handle non-job fence in error paths

Fixes: db36632ea5 ("drm/amdgpu: clean up and unify hw fence handling")

d95ca7f515 drm/amdgpu: suspend ras module before gpu reset
During gpu reset, all GPU-related resources are
inaccessible. To avoid affecting ras functionality,
suspend ras module before gpu reset and resume
it after gpu reset is complete.

V2:
  Rename functions to avoid misunderstanding.

V3:
  Move flush_delayed_work to amdgpu_ras_process_pause,
  Move schedule_delayed_work to amdgpu_ras_process_unpause.

V4:
  Rename functions.

V5:
  Move the function to amdgpu_ras.c.

To fix regression report on gfx8, which requires the exhaustive search

The high CPU usage of KFD interrupt wq issue is gone after HIP/ROCr add
option to reduce HW event interrupts, safe to revert this optimization

ac7f4fcc7b drm/amd/display: Revert DCN4 max buffered cursor size to 64
[Why & How]
The buffered cursor cap is expressed assuming a square cursor, and usage
of the cursor buffer is limited by the request size. For greater than 32
pixels, the request size is fixed at 256 bytes, so the maximum width
must be floored to the nearest 256th byte. At 4bpp this means even with
24kB DCN4 can only hold a 64x64 cursor in the buffer as even 65 pixels
would require 512 bytes per line instead of 256.

[Why]
The inbox1 infrastructure is deprecated, so to support display
power features requiring a DMUB interlock moving forward extend
the inbox0 locking conditions to also include Replay or PSR.

[How]
Implemented a series of changes to improve HW lock handling:
- Deprecated should_use_dmub_inbox1_lock() and guarded it with
  DCN401 flag.
- Migrated lock checks into inbox0 helpers and added PSR/Replay
  enablement checks to ensure correct behavior.
- Updated HWSS fast update path to acquire HW lock as needed
  using the new helpers.

face6a3615 drm/amd/display: fw locality check refactors
[why]
There are some new changes for HDCP2 firmware locality check. The
implementation doesn't perfectly fit the intended design and clarity.

1. Clarify and consolidate variable responsibilities.
The previous implementation introduced the following variables:
- config.ddc.funcs.atomic_write_poll_read_i2c (optional pointer)
- hdcp->config.ddc.funcs.atomic_write_poll_read_aux (optional pointer)
- hdcp->connection.link.adjust.hdcp2.force_sw_locality_check (bool)
- hdcp->config.debug.lc_enable_sw_fallback (bool)
- use_fw (bool)
They will be used together to determine two operations:
- Whether to use FW locality check
- Whether to use SW fallback on FW locality check failure
The refactor streamlines this by introducing two variables in the hdcp2
link adjustment, while ensuring function pointers are always assigned
and remain independent from policy decisions:
- use_fw_locality_check (bool) -> true if fw locality should be used.
- use_sw_locality_fallback (bool) -> true to reset use_fw_locality_check
back to false and retry on fw locality check failure.

2. Mixed meanings of l_prime_read transition input
l_prime_read originally means if l_prime is read when sw locality check
is used. When FW locality check is used, l_prime_read means if lc init
write, l prime poll and l_prime read combo operation is successful. The
mix of meanings is confusing. The refactor introduces a new variable
l_prime_combo_read to isolate the second meaning into its own variable.

3. Missing specific error code on firmware locality error.
The original change reuses the generic DDC failure error code when
firmware fails to return locality check result. This is not ideal as
DDC failure indicates an error occurred during an I2C/AUX transaction.
FW locality failure could be caused by polling timeout in firmware or
failure to acquire firmware access. Which sits at a higher level of
abstraction above DDC hardware. An incorrect error code could mislead
the debug into a wrong direction.

4. Correcting misplaced comments. The previous implementation of the
firmware locality check resulted in some comments in hdcp2_transition
being incorrectly positioned. This refactor relocates those comments to
their appropriate locations for better clarity.

290f46cf57 drm/amdgpu: Implement user queue reset functionality
This patch adds robust reset handling for user queues (userq) to improve
recovery from queue failures. The key components include:

1. Queue detection and reset logic:
   - amdgpu_userq_detect_and_reset_queues() identifies failed queues
   - Per-IP detect_and_reset callbacks for targeted recovery
   - Falls back to full GPU reset when needed

2. Reset infrastructure:
   - Adds userq_reset_work workqueue for async reset handling
   - Implements pre/post reset handlers for queue state management
   - Integrates with existing GPU reset framework

3. Error handling improvements:
   - Enhanced state tracking with HUNG state
   - Automatic reset triggering on critical failures
   - VRAM loss handling during recovery

4. Integration points:
   - Added to device init/reset paths
   - Called during queue destroy, suspend, and isolation events
   - Handles both individual queue and full GPU resets

The reset functionality works with both gfx/compute and sdma queues,
providing better resilience against queue failures while minimizing
disruption to unaffected queues.

v2: add detection and reset calls when preemption/unmaped fails.
    add a per device userq counter for each user queue type.(Alex)
v3: make sure we hold the adev->userq_mutex when we call amdgpu_userq_detect_and_reset_queues. (Alex)
   warn if the adev->userq_mutex is not held.
v4: make sure we have all of the uqm->userq_mutex held.
   warn if the uqm->userq_mutex is not held.

v5: Use array for user queue type counters.(Alex)
    all of the uqm->userq_mutex need to be held when calling detect and reset.  (Alex)

v6: fix lock dep warning in amdgpu_userq_fence_dence_driver_process

v7: add the queue types in an array and use a loop in amdgpu_userq_detect_and_reset_queues (Lijo)
v8: remove atomic_set(&userq_mgr->userq_count[i], 0).
   it should already be 0 since we kzalloc the structure (Alex)
v9: For consistency with kernel queues, We may want something like:
   amdgpu_userq_is_reset_type_supported (Alex)

825df7ff4b drm/amd/display: Don't stretch non-native images by default in eDP
commit 978fa2f6d0 ("drm/amd/display: Use scaling for non-native
resolutions on eDP") started using the GPU scaler hardware to scale
when a non-native resolution was picked on eDP. This scaling was done
to fill the screen instead of maintain aspect ratio.

The idea was supposed to be that if a different scaling behavior is
preferred then the compositor would request it.  The not following
aspect ratio behavior however isn't desirable, so adjust it to follow
aspect ratio and still try to fill screen.

Note: This will lead to black bars in some cases for non-native
resolutions. Compositors can request the previous behavior if desired.
