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.
