drm/amdgpu: move the drm client creation behind drm device registration

2024-01-31T20:33:52Z

This patch is to eliminate interrupt warning below: "[drm] Fence fallback timer expired on ring sdma0.0". An early vm pt clearing job is sent to SDMA ahead of interrupt enabled. And re-locating the drm client creation following after drm_dev_register looks like a more proper flow. v2: wrap the drm client creation Fixes: 1819200166ce ("drm/amdkfd: Export DMABufs from KFD using GEM handles") Signed-off-by: Le Ma Reviewed-by: Felix Kuehling Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu: Enable GFXOFF for Compute on GFX11

2024-01-18T21:45:19Z

On GFX version 11, GFXOFF was disabled due to a MES KIQ firmware issue, which has since been fixed after version 64. This patch only re-enables GFXOFF for GFX version 11 if the GPU's MES KIQ firmware version is newer than version 64. V2: Keep GFXOFF disabled on GFX11 if MES KIQ is below version 64. V3: Add parentheses to avoid GCC warning for parentheses: "suggest parentheses around comparison in operand of ‘&’" V4: Remove "V3" from commit title V5: Change commit description and insert 'Acked-by' Signed-off-by: Ori Messinger Acked-by: Alex Deucher Reviewed-by: Harish Kasiviswanathan Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdkfd: Export DMABufs from KFD using GEM handles

2023-12-13T20:09:55Z

Create GEM handles for exporting DMABufs using GEM-Prime APIs. The GEM handles are created in a drm_client_dev context to avoid exposing them in user mode contexts through a DMABuf import. Signed-off-by: Felix Kuehling Reviewed-by: Ramesh Errabolu Signed-off-by: Alex Deucher

drm/amdkfd: Move TLB flushing logic into amdgpu

2023-11-17T14:29:53Z

This will make it possible for amdgpu GEM ioctls to flush TLBs on compute VMs. This removes VMID-based TLB flushing and always uses PASID-based flushing. This still works because it scans the VMID-PASID mapping registers to find the right VMID. It's only slightly less efficient. This is not a production use case.

drm/amdkfd: drop struct kfd_cu_info

2023-10-03T19:41:13Z

I think this was an abstraction back from when kfd supported both radeon and amdgpu. Since we just support amdgpu now, there is no more need for this and we can use the amdgpu structures directly. This also avoids having the kfd_cu_info structures on the stack when inlining which can blow up the stack.
