Did anybody noticed the following bugs and behavior in stock kernel CPU controls ? If not, can you please post your ROM/build/kernel versions or even firmware version? Maybe some firmwares are fixed?

- Setting max CPU frequency actually change kernel internal min CPU frequency! eg if I set 1GHz max frequency, all cores jump to 1GHz minimum! Setting min CPU frequency seems to have no effect. Only a reboot can recover from this, sadly.

- Setting governor to interactive_eglinteractive freezes the phone which then reboots after a while.

- There doesn't seem to be any mpdecision module running, so all cores are always online, except maybe second CPU cores are turned-off in standby.

On the positive side, it appears that controlling online states of individual cores works well, good to turn off cores when screen's off for example.

I'm running latest received OTA: Android 4.3, kernel 3.4.39-2641344, build version JSS15J.N7505POUBND2.

Most of the features you are talking will not work correctly without a custom OC kernel....So let it be like it is untill we get a custom kernel....
