NAME

       cpufreq-set - A small tool which allows to modify cpufreq settings.

SYNTAX

       cpufreq-set [options]

DESCRIPTION

       cpufreq-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

       -c --cpu <CPU>
              number of CPU where cpufreq settings shall be modified.

       -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

       -h --help
              Prints out the help screen.

REMARKS

       Omitting the -c or --cpu argument is equivalent to setting it to  zero.

       The  -f  FREQ,  --freq FREQ parameter cannot be combined with any other
       parameter except the -c CPU, --cpu CPU 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.
