NAME¶
cpupower-frequency-set - A small tool which allows to modify cpufreq settings.
SYNTAX¶
cpupower [ -c cpu ] frequency-set [
options]
DESCRIPTION¶
cpupower frequency-set allows you to modify cpufreq settings without having to
type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed"
all the time.
OPTIONS¶
- -d --min <FREQ>
- new minimum CPU frequency the governor may select.
- -u --max <FREQ>
- new maximum CPU frequency the governor may select.
- -g --governor <GOV>
- new cpufreq governor.
- -f --freq <FREQ>
- specific frequency to be set. Requires userspace governor to be available
and loaded.
- -r --related
- modify all hardware-related CPUs at the same time
By default values are applied on all cores. How to modify single core
configurations is described in the
cpupower(1) manpage in the --cpu option
section.
The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter.
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing
the value with the wanted unit name, without any space (frequency in kHz =^ Hz
* 0.001 =^ MHz * 1000 =^ GHz * 1000000).
On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.
