That's fundamentally different to a deep idle state. I think Alan and Thomas but certainly I am saying is that you can get to the same state without suspend. Either you suspend (forcefully don't schedule stuff), or you end up blocking all tasks on QoS/resource limits and end up with an idle system that goes into a deep idle state (aka suspend). So why isn't blocking every task on a QoS/resource good enough for you? _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
