VRAM+TT bos that are evicted from VRAM to TT may remain in TT also after a revalidation following eviction or suspend. This manifests itself as applications becoming sluggish after buffer objects get evicted or after a resume from suspend or hibernation. If the bo supports placement in both VRAM and TT, and we are on DGFX, mark the TT placement as fallback. This means that it is tried only after VRAM + eviction. This flaw has probably been present since the xe module was upstreamed but use a Fixes: commit below where backporting is likely to be simple. For earlier versions we need to open- code the fallback algorithm in the driver. v2: - Remove check for dgfx. (Matthew Auld) - Update the xe_dma_buf kunit test for the new strategy (CI) - Allow dma-buf to pin in current placement (CI) - Make xe_bo_validate() for pinned bos a NOP.
