Re: git: powerd - Initial load monitor and cpu frequency adjustm
Heh, finally the p-state stuffs are used :D
Since the freq of a cpu domain could be changed independent of the
other cpu domains, we could calculate the avg cpu load within one cpu
domain, instead of calculating the avg load of all cpus, and only
change the freq of that specific cpu domain.
