I am not sure I understand what performance control mean here. Can you please elaborate a bit more on that ? For example, with current code and understanding, a cpufreq policy belongs to a group of CPUs which change their frequency together, which also mean that they change their performance level together and so I am not able to understand what's going on here. Sorry about that. What kind of hardware configuration doesn't work with this ? -- viresh
