Perhaps an "airline mode" sort of thing? Even if drivers don't know how much power their devices consume (and generally I wouldn't expect them to), it still makes sense to offer userspace the discretionary power to force devices into a low-power mode. USB does this. Alan Stern _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
