DESCRIPTION

17       cpupower   is  a  collection  of tools to examine and tune power saving
18       related features of your processor.
19
20       The manpages  of  the  subcommands  (cpupower-<subcommand>(1))  provide
21       detailed  descriptions  of supported features. Run cpupower help to get
22       an overview of supported subcommands.

Options

26       --help, -h
27           Shows supported subcommands and general usage.
28
29       --cpu cpulist,  -c cpulist
30           Only show or set values for specific cores.   This  option  is  not
31           supported  by all subcommands, details can be found in the manpages
32           of the subcommands.
33
34           Some subcommands access all cores (typically the  *-set  commands),
35           some  only  the  first  core  (typically  the  *-info  commands) by
36           default.
37
38           The syntax for <cpulist> is based on how  the  kernel  exports  CPU
39           bitmasks via sysfs files. Some examples:
