What i'm saying is that your approach: "Hey, I'm going to suspend, in the time available before I go to sleep, do whatever you can do!" is faulty, imo. What we are doing in Maemo is: App1 changes states -> App1 saves its state using library App2 changes states -> App2 saves its state using library App3 changes states -> App3 saves its state using library App4 changes states -> App4 saves its state using library .... Suspend event -> Apps do nothing Very simple and deterministic. Note also that you can track is Apps are saving their state by refcounting and therefore delaying the actual suspend command. I hope that it's clear now. cheers, igor -- Cheers, Igor Igor Stoppa <igor.stoppa@xxxxxxxxx> (Nokia Multimedia - CP - OSSO / Helsinki, Finland) _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
