| \fBcpupower \fP 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

| 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:
