drm/amdgpu: Fix double deletion of validate_list

2026-02-03T22:24:21+00:00

If amdgpu_amdkfd_gpuvm_free_memory_of_gpu() fails after kgd_mem is
removed from validate_list, the mem handle still lingers in the KFD idr.
This means when process is terminated,
kfd_process_free_outstanding_kfd_bos() will call
amdgpu_amdkfd_gpuvm_free_memory_of_gpu() again resulting in double
deletion.

To avoid this -
 (a) Check if list is empty before deleting it
 (b) Rearragne amdgpu_amdkfd_gpuvm_free_memory_of_gpu() such that it can
     be safely called again if it returns failure the first time.

drm/amd/display: remove assert around dpp_base replacement

There is nothing wrong if in_shaper_func type is DISTRIBUTED POINTS.
Remove the assert placed for a TODO to avoid misinterpretations.

drm/amd/display: extend delta clamping logic to CM3 LUT helper

2026-02-03T22:21:50+00:00

Commit 27fc10d1095f ("drm/amd/display: Fix the delta clamping for shaper
LUT") fixed banding when using plane shaper LUT in DCN10 CM helper.  The
problem is also present in DCN30 CM helper, fix banding by extending the
same bug delta clamping fix to CM3.

drm/amd/display: fix wrong color value mapping on MCM shaper LUT

2026-02-03T22:21:43+00:00

Some shimmer/colorful points appears when using the steamOS color
pipeline for HDR on gaming with DCN32. These points look like black
values being wrongly mapped to red/blue/green values. It was caused
because the number of hw points in regular LUTs and in a shaper LUT was
treated as the same.

DCN3+ regular LUTs have 257 bases and implicit deltas (i.e. HW
calculates them), but shaper LUT is a special case: it has 256 bases and
256 deltas, as in DCN1-2 regular LUTs, and outputs 14-bit values.

Fix that by setting by decreasing in 1 the number of HW points computed
in the LUT segmentation so that shaper LUT (i.e. fixpoint == true) keeps
the same DCN10 CM logic and regular LUTs go with `hw_points + 1`.

Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem"

2026-02-03T22:20:59+00:00

This reverts commit 7294863a6f01248d72b61d38478978d638641bee.

This commit was erroneously applied again after commit 0ab5d711ec74
("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device")
removed it, leading to very hard to debug crashes, when used with a system with two
AMD GPUs of which only one supports ASPM.

drm/amd: Set minimum version for set_hw_resource_1 on gfx11 to 0x52

2026-02-03T22:20:38+00:00

commit f81cd793119e ("drm/amd/amdgpu: Fix MES init sequence") caused
a dependency on new enough MES firmware to use amdgpu.  This was fixed
on most gfx11 and gfx12 hardware with commit 0180e0a5dd5c
("drm/amdgpu/mes: add compatibility checks for set_hw_resource_1"), but
this left out that GC 11.0.4 had breakage at MES 0x51.

Bump the requirement to 0x52 instead.
