drm/amdkfd: fix null pointer panic while free buffer in kfd

2021-02-02T15:47:47Z

In drm_gem_object_free, it will call funcs of drm buffer obj. So kfd_alloc should use amdgpu_gem_object_create instead of amdgpu_bo_create to initialize the funcs as amdgpu_gem_object_funcs.

drm/amdkfd: keep BOs in system memory if restore failed

2020-12-01T21:04:10Z

If vram is used up, display allocate vram evict the KFD BOs to system memory. KFD schedule restore work to restore BOs back to vram. If display BOs are pinned in vram, KFD restore work will keep retry, and may never success. If restore BO back to vram failed, keep the BO in system memory to prevent endless retry restore, and GPU mapping will update to system memory.
