I sent out a similar patch a week ago [1]. [1] https://patchwork.ozlabs.org/project/linux-tegra/patch/20200514210847.9269-2-digetx@xxxxxxxxx/ The pm_runtime_put_noidle() should have the same effect as yours variant, although my variant won't change the last_busy RPM time, which I think is a bit more appropriate behavior. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
