Hi,

The real fix is in patch 2. The rest is a helper that adds
the with_intel_gt_pm_if_awake() (from Chris) and one more check
on the status of the engine before accessing it for clearing the
TLB.

  drm/i915/gem: Flush TLBs for all the tiles when clearing an obj
  drm/i915/gt: Skip TLB invalidation if the engine is not awake

Chris Wilson (1):
  drm/i915/gt: Ignore TLB invalidations on idle engines
