drm/amdgpu: fix clearing mappings for BOs that are always valid in VM

2023-07-23T11:54:04+00:00

commit ea2c3c08554601b051d91403a241266e1cf490a5 upstream. Per VM BOs must be marked as moved or otherwise their ranges are not updated on use which might be necessary when the replace operation splits mappings. This fixes random GPU hangs when replacing sparse mappings from the userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs are correctly handled there.

drm/amdgpu: make sure BOs are locked in amdgpu_vm_get_memory

commit e2ad8e2df432498b1cee2af04df605723f4d75e6 upstream. We need to grab the lock of the BO or otherwise can run into a crash when we try to inspect the current location.

amdgpu: validate offset_in_bo of drm_amdgpu_gem_va

2023-07-19T14:35:59+00:00

[ Upstream commit 9f0bcf49e9895cb005d78b33a5eebfa11711b425 ] This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows. v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl Fixes: 9f7eb5367d00 ("drm/amdgpu: actually use the VM map parameters") Reviewed-by: Christian König Signed-off-by: Chia-I Wu Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdgpu: move vmhub out of amdgpu_ring_funcs (v4)

2023-04-14T17:47:49+00:00

It looks better to place this field in ring structure. Also drop the repeated ring funcs definitions if there's no difference except for vmhub field. v2: rename the field to vm_hub like others (Le) v3: apply the changes to new ip blocks (Hawking) v4: fix vcn sw ring (Alex) Signed-off-by: Le Ma Reviewed-by: Christian König Reviewed-by: Hawking Zhang Signed-off-by: Hawking Zhang Signed-off-by: Alex Deucher
