I recently wrote myself a submitoverhead igt test[1] and spent a bit of
time profiling.  The end result ranges from 1.6x faster for
NO_IMPLICIT_SYNC commits with 100 BOs to 2.5x faster for 1000 BOs.

Rob Clark (4):
  drm/msm: Take lru lock once per job_run
  drm/msm: Use drm_gem_object in submit bos table
  drm/msm: Take lru lock once per submit_pin_objects()
  drm/msm: Remove vma use tracking
