CPUPOWER-FREQUENCY-SET(1)					  cpupower Manual					 CPUPOWER-FREQUENCY-SET(1)

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/scal-
       ing_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

       REMARKS

       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 (fre-
       quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).

       On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.

FILES

       /sys/devices/system/cpu/cpu*/cpufreq/
