So does your application change the default values, and do these value remain after closing the app?

You can close the application and the settings should be saved until you reboot the device or plug/unplug the charger.

The easiest way: play a CPU-intensive game (like Bounce Evolution) and log on to your device using SSH. While playing the game issue this command:

Code:

cat /proc/cpuinfo |grep -i bogomips

and watch the speed of your CPU.

However 250 MHz seems to be a very low speed. I just noticed that for some reason the frequency goes up one level if you set minspeed=maxspeed. If you'd set your maxspeed to 250MHz then your CPU will effectively use 500MHz (the next step on the scaling scale) as maxfreq. This is very strange - maybe it's a kernel bug (or feature

).

I guess I am going to remove the lowest scaling step (250MHz on vanilla kernel) in the next version as it might confuse people.
