Disable all optional CPU mitigations. This improves system performance,
but it may also expose users to several CPU vulnerabilities.
This will add the following option to the Kernel commandline:
* ``mitigations=off``
.. note:: Setting will only become active with the next reboot!
.. cfgcmd:: set system option kernel disable-power-saving
Disable CPU power saving mechanisms also known as C states.
This will add the following two options to the Kernel commandline:
* ``intel_idle.max_cstate=0`` Disable intel_idle and fall back on acpi_idle
* ``processor.max_cstate=1`` Limit processor to maximum C-state 1
.. note:: Setting will only become active with the next reboot!
