there are two possible answers for this ;) 1) For really low power syatems, "once every 30 seconds" is nice :0 But to be realistic, if you use round_jiffies(), it won't be all that bad or answer 2 2) use deferrable timers. These are like normal timers, but don't happen when the system is totally idle, but just instead fire when you get out of idle (say, when a network interrupt happens). This could be the best of both worlds in this case; if there's no network traffic or any other activity, the timer doesn't happen, but if there's activity it'll happen as usual _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
