drm/amdgpu: Check BO's requested pinning domains against its preferred_domains 2022-08-17T12:40:13+00:00 Leo Li sunpeng.li@amd.com 2022-07-12T16:30:29+00:00 f62f12ac1f57c4058dded6bc5982623e86eda319 commit f5ba14043621f4afdf3ad5f92ee2d8dbebbe4340 upstream. When pinning a buffer, we should check to see if there are any additional restrictions imposed by bo->preferred_domains. This will prevent the BO from being moved to an invalid domain when pinning. For example, this can happen if the user requests to create a BO in GTT domain for display scanout. amdgpu_dm will allow pinning to either VRAM or GTT domains, since DCN can scanout from either or. However, in amdgpu_bo_pin_restricted(), pinning to VRAM is preferred if there is adequate carveout. This can lead to pinning to VRAM despite the user requesting GTT placement for the BO. v2: Allow the kernel to override the domain, which can happen when exporting a BO to a V4L camera (for example).
