[ I sent this yesterday to the i915 mailing list only:
  https://patchwork.freedesktop.org/series/140538/
  Re-sending to the right one ]

The current reading of engine utilization has same races. This should
fix most of them while also drastically reducing the update rate needed
on "normal apps".

I left tests/xe_drm_fdinfo running on 2 systems and saw no failures
after 100 iterations.

Lucas De Marchi (3):
  drm/xe: Add trace to lrc timestamp update
  drm/xe: Accumulate exec queue timestamp on destroy
  drm/xe: Stop accumulating LRC timestamp on job_free
