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 commands (cpupower-<command>(1))  provide  detailed
21       descriptions  of  supported features. Run cpupower help to get an over‐
22       view of supported commands.

Options

26       --help, -h
27           Shows supported commands 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 commands, details can be found in the manpages of
32           the commands.
33
34           Some commands access all cores (typically the *-set commands), some
35           only the first core (typically the *-info commands) by default.
36
37           The  syntax  for  <cpulist>  is based on how the kernel exports CPU
38           bitmasks via sysfs files. Some examples:
