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


       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 (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.
