it is slightly more subtle than that (the HTML report shows that better visually); PowerTOP shows 100% only for those devices that claim to support runtime PM, but then are 100% busy (either because the user hasn't enabled runtime PM for the device, or the driver is such that it's 100% busy) devices that do not support runtime PM at all will not show up (but show up in the HTML report in their separate section) _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
