[PATCH 0/6] Implement compression support on BMG

[Akshata Jahagirdar <akshata.jahagirdar@intel.com>]

According to the SAS for BMG compression, we need to decompress during eviction,
and not recompress on restore. Due to this, we need to introduce encoding pat_index
in case of vram too. This patch explores the solution of setting up an additional
identity map for the vram, this time at the end of previous mapping offset and
with compressed pat_index. 
We then select the appropriate mapping during eviction/restore/clear.

Akshata Jahagirdar (6):
  drm/xe/xe2: Introduce identity map for compressed pat for vram
  drm/xe/migrate: Handle clear ccs logic for xe2 dgfx
  drm/xe/migrate: Add kunit to test clear functionality
  drm/xe/xe_migrate: Handle migration logic for xe2+ dgfx
  drm/xe/migrate: Add kunit to test migration functionality for BMG
  drm/xe/xe2: Do not run xe_bo_test for xe2+ dgfx
