After a recent change in clang to expose uninitialized warnings from const variables and pointers [1], there is a warning in imu_v12_0_program_rlc_ram() because data is passed uninitialized to program_imu_rlc_ram(): drivers/gpu/drm/amd/amdgpu/imu_v12_0.c:374:30: error: variable 'data' is uninitialized when used here [-Werror,-Wuninitialized] 374 | program_imu_rlc_ram(adev, data, (const u32)size); | ^~~~ As this warning happens early in clang's frontend, it does not realize that due to the assignment of r to -EINVAL, program_imu_rlc_ram() is never actually called, and even if it were, data would not be dereferenced because size is 0. Just initialize data to NULL to silence the warning, as the commit that added program_imu_rlc_ram() mentioned it would eventually be used over the old method, at which point data can be properly initialized and used.

2025-07-16drm/amd/display: Disable CRTC degamma LUT for DCN401Melissa Wen
In DCN401 pre-blending degamma LUT isn't affecting cursor as in previous DCN version. As this is not the behavior close to what is expected for CRTC degamma LUT, disable CRTC degamma LUT property in this HW. Link: https://gitlab.freedesktop.org/drm/amd/-/issues/4176 --- When enabling HDR on KDE, it takes the first CRTC 1D LUT available and apply a color transformation (Gamma 2.2 -> PQ). AMD driver usually advertises a CRTC degamma LUT as the first CRTC 1D LUT, but it's actually applied pre-blending. In previous HW version, it seems to work fine because the 1D LUT was applied to cursor too, but DCN401 presents a different behavior and the 1D LUT isn't affecting the hardware cursor. To address the wrong gamma on cursor with HDR (see the link), I came up with this patch that disables CRTC degamma LUT in this hw, since it presents a different behavior than others. With this KDE sees CRTC regamma LUT as the first post-blending 1D LUT available. This is actually more consistent with AMD color pipeline. It was tested by the reporter, since I don't have the HW available for local testing and debugging.

2025-07-16drm/amdgpu: Replace HQD terminology with slots namingJesse Zhang
The term "HQD" is CP-specific and doesn't accurately describe the queue resources for other IP blocks like SDMA, VCN, or VPE. This change: 1. Renames `num_hqds` to `num_slots` in amdgpu_kms.c to better reflect the generic nature of the resource counting 2. Updates the UAPI struct member from `userq_num_hqds` to `userq_num_slots` 3.

Added userq_num_instance field to drm_amdgpu_info_hw_ip structure 2.
