drm/amdgpu: Restore uncached behaviour on GFX12

2025-03-18T20:29:52Z

Always use MTYPE_UC if UNCACHED flag is specified. This makes kernarg region uncached and it restores usermode cache disable debug flag functionality. Do not set MTYPE_UC for COHERENT flag, on GFX12 coherence is handled by shader code.

drm/amdgpu/gfx12: correct cleanup of 'me' field with gfx_v12_0_me_fini()

2025-03-18T20:29:16Z

In gfx_v12_0_cp_gfx_load_me_microcode_rs64(), gfx_v12_0_pfp_fini() is incorrectly used to free 'me' field of 'gfx', since gfx_v12_0_pfp_fini() can only release 'pfp' field of 'gfx'. The release function of 'me' field should be gfx_v12_0_me_fini().

drm/amdgpu: NULL-check BO's backing store when determining GFX12 PTE flags

2025-03-12T18:59:21Z

PRT BOs may not have any backing store, so bo->tbo.resource will be NULL. Check for that before dereferencing.

drm/amd: Keep display off while going into S4

2025-03-10T18:09:09Z

When userspace invokes S4 the flow is: 1) amdgpu_pmops_prepare() 2) amdgpu_pmops_freeze() 3) Create hibernation image 4) amdgpu_pmops_thaw() 5) Write out image to disk 6) Turn off system Then on resume amdgpu_pmops_restore() is called. This flow has a problem that because amdgpu_pmops_thaw() is called it will call amdgpu_device_resume() which will resume all of the GPU. This includes turning the display hardware back on and discovering connectors again. This is an unexpected experience for the display to turn back on. Adjust the flow so that during the S4 sequence display hardware is not turned back on.
