[PATCH v3 0/6] Fix non-contiguous VRAM BO access in Xe

[Matthew Brost]

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

v2:
 - Include missing local change
v3:
 - Use GPU for non-visible access
 - Take PM ref in xe_ttm_access_memory
 - Disable VMAP for non-contiguous BOs

Matthew Brost (6):
  drm/ttm: Add ttm_bo_access
  drm/xe: Add xe_ttm_access_memory
  drm/xe: Update xe_ttm_access_memory to use GPU for non-visible access
  drm/xe: Use ttm_bo_access in xe_vm_snapshot_capture_delayed
  drm/xe: Set XE_BO_FLAG_PINNED in migrate selftest BOs
  drm/xe: Only allow contiguous BOs to use xe_bo_vmap
