CPU frequency scaling in Linux June 22, 2008

Posted by idebian in Debian, GNU/Linux, Hardware.

The recent CPUs have a feature which let them scale their operating frequency (changing a voltage power supply input) according to the system/user needs.
This way, when the entire processor resources are not needed, the system can greatly reduces the overall power consumption, lowering temperatures and fan speed 😉

This post addresses the frequency scaling setup in Linux: enjoy 😀
