|
|
related features of your processor.
|

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:
