Perhaps "horsepower" is better term.
Well ... I don't think "horsepower" is a step in the right direction.
Andrew's point was over the word "power", not "cpu". The term "cpu_power" suggested to him we were concerned with the power supply watts consumed by a group of CPUs. Indeed, both those concerned with laptop battery lifetimes, and the air conditioning tonnage needed for big honkin NUMA iron might have reason to be concerned with the power consumed by CPUs.
Changing the word "cpu" to "horse", but keeping the word "power", does nothing to address Andrew's point. Rather it just adds more confusion. We are obviously dealing with CPUs here, not horses.
My understanding is that the "cpu_power" of the cpus in a sched group is rougly proportional to the BogoMIPS of the CPUs in that group.
