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‐
       ingsetspeed" all the time.

OPTIONS
       -d min 
              new minimum CPU frequency the governor may select.

       -u max 
              new maximum CPU frequency the governor may select.

       -g governor 
              new cpufreq governor.

       -f 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.
