I think I should say this "post idling GPU and display suspend". Will
update in next rev.
suspend. GPU is reset in i915_gem_suspend. This separated the HW suspend
across reset. To achieve the complete HW cleanup prior to GPU reset we
need to separate i915_gem_suspend functionality into user quiescing
and HW cleanup. With this patch new function i915_gem_quiescent
And this should have been named "i915_gem_quiesce"?
Chris, Joonas, does i915_gem_quiesce for user quiescing and
i915_gem_suspend for HW suspend look good?
The BAT results seemed quite negative.
Yes. Addressed as part of GEM/GuC fixes series.
