DESCRIPTIONcpupower is a collection of tools to examine and tune power saving
related features of your processor.
The manpages of the subcommands (cpupower-<subcommand>(1)) provide
detailed descriptions of supported features. Run cpupower help to get
an overview of supported subcommands.
Options--help, -h
Shows supported subcommands and general usage.
--cpu cpulist, -c cpulist
Only show or set values for specific cores. This option is not
supported by all subcommands, details can be found in the manpages
of the subcommands.
Some subcommands 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:
