I am studying intel speed select:
"reducing the frequency for low priority jobs to maintain high frequency on a high priority job"
In my understanding, Linux already can set different freq to different core.
and Linux (OS) also know each task's expected freq ( heavy loading or light loading, ex: load a web page or print one line log ), OS should able to do this kind of tech ( Intel speed select ) already.
Does Linux support this kind of feature (but not the intel speed select) in the kernel already?
What's the new in Intel speed select and linux kernel? ( in my understanding, kernel will support Intel speed select )
