When one thinks about the modern world and especially AMD CPUs that can already do per-CPU(group) states, setting the minimum and maximum sounds attractive and reasonable. For instance, if you set CPUs offline, also the frequency should scale down. > i'd like to re-iterate what i said earlier though -- i'd really much > rather this became real-code in the tree sooner than when it becomes > a perfect API. Fine. Let's start by importing a proplist of MHzs to cpuctl(8). At least the current mess is solved. - Jukka.
