[PATCH v2 0/2] drm/xe: Adjust the bo shrinker batch size

Shamelessly stolen from i915, To avoid gpu stalls for small
shrinker request, Set the shrinker batch size to the average
size of system buffer objects. Use the number of
populated struct ttm_tts to compute the average size.

v2:
- Fix the average object size estimate to account for the full
  shrinkable and purgeable population.

Thomas Hellström (2):
  drm/xe: Track number of populated ttm_tts in the shrinker
  drm/xe: Update shrinker batch size based on average BO size
