CPUPOWER(1)							  cpupower Manual						       CPUPOWER(1)

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 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 <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.
