Nope, the diff below didn't change things. Should I comment them out one by one and see whether the clockgating or the powergating causes it? diff --git a/drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c b/drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c index bc571833632e..99e3d697cc24 100644 --- a/drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c +++ b/drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c @@ -561,10 +561,10 @@ static int uvd_v6_0_hw_fini(void *handle) } else { amdgpu_asic_set_uvd_clocks(adev, 0, 0); /* shutdown the UVD block */ - amdgpu_device_ip_set_powergating_state(adev, AMD_IP_BLOCK_TYPE_UVD, - AMD_PG_STATE_GATE); amdgpu_device_ip_set_clockgating_state(adev, AMD_IP_BLOCK_TYPE_UVD, AMD_CG_STATE_GATE); + amdgpu_device_ip_set_powergating_state(adev, AMD_IP_BLOCK_TYPE_UVD, + AMD_PG_STATE_GATE); } if (RREG32(mmUVD_STATUS) != 0) diff --git a/drivers/gpu/drm/amd/amdgpu/vce_v3_0.c b/drivers/gpu/drm/amd/amdgpu/vce_v3_0.c index 9de66893ccd6..a36612357d0f 100644 --- a/drivers/gpu/drm/amd/amdgpu/vce_v3_0.c +++ b/drivers/gpu/drm/amd/amdgpu/vce_v3_0.c @@ -507,10 +507,10 @@ static int vce_v3_0_hw_fini(void *handle) amdgpu_dpm_enable_vce(adev, false); } else { amdgpu_asic_set_vce_clocks(adev, 0, 0); - amdgpu_device_ip_set_powergating_state(adev, AMD_IP_BLOCK_TYPE_VCE, - AMD_PG_STATE_GATE); amdgpu_device_ip_set_clockgating_state(adev, AMD_IP_BLOCK_TYPE_VCE, AMD_CG_STATE_GATE); + amdgpu_device_ip_set_powergating_state(adev, AMD_IP_BLOCK_TYPE_VCE, + AMD_PG_STATE_GATE); } r = vce_v3_0_wait_for_idle(handle); -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
