Perhaps an "airline mode" sort of thing modes suck... they're very much the wrong concept for power management (but that's a different story) if the user (or something on its behalf) doesn't need link detection, he can turn it off. Really. He doesn't need to know that maybe on machine one this saves some power, and on machine two that power was already mostly saved while on machine three it doesn't save anything at all. Not to mention that the driver is extremely unlikely to know how much actual power will be saved... -- Arjan van de Ven Intel Open Source Technology Centre For development, discussion and tips for power savings, visit http://www.lesswatts.org _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
