[PATCH v4 3/7] drm/msm: Correct pm_runtime votes in recover worker

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the scenario where there is one a single submit which is hung, gpu is
power collapsed when it is retired. Because of this, by the time we call
reover(), gpu state would be already clear. Fix this by correctly
managing the pm runtime votes.
