drm/amdgpu: Unmap MMIO mappings when device is not unplugged

2022-01-11T20:44:26Z

Patch: 3efb17ae7e92 ("drm/amdgpu: Call amdgpu_device_unmap_mmio() if device is unplugged to prevent crash in GPU initialization failure") makes call to amdgpu_device_unmap_mmio() conditioned on device unplugged. This patch unmaps MMIO mappings even when device is not unplugged. v2: Add condition of drm_dev_enter() to deleted unmaps in patch "drm/amdgpu: Unmap all MMIO mappings" Signed-off-by: Leslie Shi Reviewed-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

drm/amdgpu: return early on error while setting bar0 memtype

2021-11-17T21:58:04Z

We set WC memtype for aper_base but don't check return value of arch_io_reserve_memtype_wc(). Be more defensive and return early on error. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Fix dangling kfd_bo pointer for shared BOs

2021-11-05T18:12:45Z

If a kfd_bo was shared (e.g. a dmabuf export), the original kfd_bo may be freed when the amdgpu_bo still lives on. Free the kfd_bo struct in the release_notify callback then the amdgpu_bo is freed.

drm/amdgpu: rename amdgpu_bo_get_preferred_pin_domain

2021-08-25T22:15:17Z

amdgpu_bo_get_preferred_pin_domain is used for page tables creation, which is not involved with page pinning. And it is used in more cases than display scanout, modify its documentation as well. Signed-off-by: Yifan Zhang Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: use the preferred pin domain after the check

2021-08-20T16:09:32Z

For some reason we run into an use case where a BO is already pinned into GTT, but should be pinned into VRAM|GTT again. Handle that case gracefully as well. Reviewed-by: Shashank Sharma Reviewed-by: Alex Deucher Signed-off-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
