drm/amdgpu: Reduce dequeue retry timeout for gfx9 family

2025-03-14T03:10:38Z

Dequeue retry timeout controls the interval between checks for unmet conditions. On MI series, reduce this from 0x40 to 0x1 (~ 1 uS). The cost of additional bandwidth consumed by CP when polling memory shouldn't be substantial. Signed-off-by: Harish Kasiviswanathan Reviewed-by: Jonathan Kim Signed-off-by: Alex Deucher

drm/amdkfd: implement per queue sdma reset for gfx 9.4+

2025-03-05T15:47:26Z

To reset hung SDMA queues on GFX 9.4+ for the GFX9 family, a soft reset must be issued through SMU. Since soft resets will reset an entire SDMA engine, use a common KGD call to do the reset as the KGD will handle avoiding a reset of in flight GFX and paging queues on that engine. In addition, create a common call for all reset types to simplify the handling of module parameter settings that block gpu resets.

drm/amd/display: Add a new dcdebugmask to allow turning off brightness curve

2025-03-05T15:42:57Z

Upgrading the kernel may cause some systems that were previously not using a firmware specified brightness curve to use one. In the event of problems with this curve (for example an interpolation error) add a new dcdebugmask value that can be used to turn it off. Also add an info message to show that custom brightness curves are currently in use.
