If no devices are being used, and next wakeup is far enough in the future, just put system to sleep. Long enough == so far away that suspend/wakeup is short compared to that... like 20 seconds on PC. Ok, it probably needs to be opt-in: echo auto-mem > /sys/power/state should do the trick. This will need either fixing all the applications not to poll, or maybe someone SIGSTOP-ing apps that are in background and poll too often. > (2) put given subset of devices into low power states whenever they are not > used, without putting the entire system into a sleep state. Arjan said this nicely...
