Message

Mapping a non-contiguous VRAM BO doesn't work, start to fix this.

A follow up series should cleanup any remaining mapping of
non-contiguous VRAM BOs, add non-visible access support to
xe_ttm_access_memory, and warn / error on mapping a BO which cannot be
mapped.

v2:
 - Include missing local change

Matthew Brost (3):
  drm/ttm: Add ttm_bo_access
  drm/xe: Add xe_ttm_access_memory
  drm/xe: Use ttm_bo_access in xe_vm_snapshot_capture_delayed
