Hi Viresh, I never use performance governor, but I want improved performance with ondemand. Why do you suspect significant increased power? With ondemand the CPU will go down to lowest freq as soon as the load will decreased. And the measurement shows that the CPU load will decrease faster

I'm sorry, I don't understand. The goal of this patch is not energy saving. The goal is to detect CPU load as soon as possible to increase frequency. Could you please clarify this? Thanks, Stratos "Rafael J. Wysocki" wrote: >On Tuesday, April 02, 2013 06:49:14 PM Stratos Karafotis wrote: >>
