" Here are some notes on getting CPU frequency scaling working on Linux. CPU frequency scaling does what it sounds like. It will raise and lower the frequency of your processor depending on a set level of demand being made on the processor at the time. One of the reasons you might want to do this would be to save energy. This could save you money on your electric bills or battery life on a laptop. It will also lower the temperature of your processor(s) to keep your machine cooler.
The following examples are done using K/X/Ubuntu distribution using a 2.6.24 kernel. Most of the settings in the examples should be the same or close to the same for any other distros. I will use apt-get the package manager installed with K/X/Ubuntu for the software install examples. You will need to use whatever package manager yours system uses. Yum (RPM) and apt-get (dpkg) are 2 very popular ones.
Before we start if you have a RedHat or Fedora machine you might want to try to install cpuspeed (yum install cpuspeed) to get frequency scaling. In K/X/Ubuntu or another Debian based machine you might just try to install cpufrequtils (sudo apt-get install cpufrequtils) to get frequency scaling working. If that does for you then you don't need to go through the parts of finding and loading the correct modules below. Just skip to the section on configuring the scaling governor."
