drm/amdgpu: WARN once if amdgpu_bo_unpin is called for an unpinned BO

2018-12-14T20:55:17Z

It indicates a pin/unpin imbalance bug somewhere. While the bug isn't necessarily in the call chain hitting this, it's at least one part involved. Reviewed-by: Alex Deucher Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amdgpu: Add KFD VRAM limit checking

2018-12-07T23:13:15Z

We don't want KFD processes evicting each other over VRAM usage. Therefore prevent overcommitting VRAM among KFD applications with a per-GPU limit. Also leave enough room for page tables on top of the application memory usage. Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Reviewed-by: Eric Huang Signed-off-by: Alex Deucher
