FWIW if this works the way I hope it does then, its a feature we need for different reasons than interactivity. So thanks for working on this! > > V2: > * split min and max to separate commits > * handle PM QoS min above max as max > * handle PM QoS max below min as min A qos to constrain how slow the cpu goes is ok. A qos to constrain how fast it is allowed to go is not a PM_QOS thing. I'll review the patchset later today.
