NAME

       cpupower - Shows and sets processor power related values

SYNOPSIS

       cpupower [ -c cpulist ] <command> [ARGS]

       cpupower -v|--version

       cpupower -h|--help

DESCRIPTION

       cpupower  is a collection of tools to examine and tune power saving related features of your processor.

       The manpages of the commands (cpupower-<command>(1)) provide detailed descriptions of supported features.
       Run cpupower help to get an overview of supported commands.

Options

       --help, -h
           Shows supported commands and general usage.

       --cpu cpulist,  -c cpulist
           Only  show  or  set values for specific cores.  This option is not supported by all commands, details
           can be found in the manpages of the commands.

           Some commands access all cores (typically the *-set commands), some only the  first  core  (typically
           the *-info commands) by default.

           The  syntax  for  <cpulist>  is  based  on  how the kernel exports CPU bitmasks via sysfs files. Some
           examples:

               Input           Equivalent to

               all             all cores

               0-3             0,1,2,3

               0-7:2           0,2,4,6

               1,3,5-7         1,3,5,6,7

               0-3:2,8-15:4    0,2,8,12

       --version,  -v
           Print the package name and version number.
