Introduction to Cpufrequtils

The cpufrequtils package consists of a library which offers an unified access method for userspace tools and programs to the CPU frequency and voltage scaling (cpufreq) subsystem in the Linux kernel, the "cpufreq-info" and "cpufreq-set" tools to determine and set cpufreq settings, and debug tools helpful if frequency scaling doesn't work as expected.

Short Description

cpufreq-info determines current cpufreq settings, and provides useful

debug information to users and bug-hunters.

cpufreq-set allows to set a specific frequency and/or new cpufreq policies

without having to type "/sys/devices/system/cpu/cpu0/cpufreq" all the time.

cpufreq-aperf calculates and displays average CPU frequency.
