cpufreq-set
modify CPU frequency scaling settings
TLDR
Set CPU frequency governor
$ sudo cpufreq-set -c [1] -g [userspace]
Set minimum CPU frequency$ sudo cpufreq-set -c [1] -d [min_frequency]
Set maximum CPU frequency$ sudo cpufreq-set -c [1] -u [max_frequency]
Set specific frequency$ sudo cpufreq-set -c [1] -f [frequency]
SYNOPSIS
cpufreq-set [options]
DESCRIPTION
cpufreq-set modifies CPU frequency settings including governor, minimum/maximum frequencies, and fixed frequency. Frequency values should be within the range shown by cpufreq-info -l.
Part of the cpufrequtils package for CPU frequency scaling management.
PARAMETERS
-c, --cpu cpu
Specify CPU number-g, --governor governor
Set frequency governor (ondemand, powersave, performance, userspace)-d, --min freq
Set minimum frequency-u, --max freq
Set maximum frequency-f, --freq freq
Set specific frequency (requires userspace governor)
CAVEATS
Requires root privileges. Setting a fixed frequency requires the userspace governor. Available governors depend on kernel configuration. Settings may not persist across reboots.
