Yes, it is using /proc/acpu/processor/../power. > > We only support a maximum of "C1" (esentially 'hlt'). Not sure how much > more of that information it needs.

I have a little systemtap script that records when the processor enter and leaves C1 state. I guess that something similar could be done to track the amount of time in suspend if the suspend/resume doesn't track that information. PowerTOP is using the /proc/timer_stats. However, there is some useful information like the pid that PowerTOP is removing from the output. -Will _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
