frankly, I don't think this really make sense... I wouldn't know what it means if a logical cpu core (half of a hyperthreading pair or half of an AMD pair) is in a state and the other half is not. The core is also a very small %age of power of the whole CPU chip (never mind SOCs) _______________________________________________ Discuss mailing list [email protected] http://lists.lesswatts.org/listinfo/discuss
