I think the cgroups approach works if you assume that applications that consume wakeup events can be trusted to otherwise be good citizens. Everything that has no direct interest in wakeup events (except the generic Android userspace) can be frozen, and you can use the scheduler to make everything else Just Work. That's a rather big if, but you've got a better idea of the state of the Android app base than I do. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
