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

       The manpages of the commands (cpupower-(1))  provide  detailed
       descriptions  of  supported features. Run cpupower help to get an over‐
       view 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    is based on how the kernel exports CPU
           bitmasks via sysfs files. Some examples:
