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
--cpu cpulist, -c cpulist
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:
--version, -v
