Clearly if it fails, there something to be done, right? So whoever does the thing will communicate with the suspend manager that it's going to do and has finished doing its thing, at which point it will try again. That's event driven, not polled. Also, if you want you can keep the kernel-side auto-suspend side, and have the suspend manager clear on !0 and re-establish the auto-suspend state on 0. But you really don't need this device thingy. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
