[PATCH v4 0/3] drm/i915/gvt: optimizaton on shadow context population

[Yan Zhao]

This patchset skips population of shadow contexts if their corresponding
guest contexts are known not changed.

patch 1 implements the skipping logic, though intentionally disabled the
skip.
patch 2 checks ggtt entry to verify guest contexts are not changed.
patch 3 turns on the skipping logic

Yan Zhao (3):
  drm/i915/gvt: skip populate shadow context if guest context not
    changed
  drm/i915/gvt: check ggtt entry modification status for guest ctxs
  drm/i915/gvt: turn on shadow context skipping
