however, so it is rather crude and not very energy-efficient. For this reason,
it is not recommended for production use.
+The ``cpuidle.governor=`` kernel command line switch allows the ``CPUIdle``
+governor to use to be specified. It has to be appended with a string matching
+the name of an available governor (e.g. ``cpuidle.governor=menu``) and that
+governor will be used instead of the default one. It is possible to force
+the ``menu`` governor to be used on the systems that use the ``ladder`` governor
+by default this way, for example.

The other kernel command line parameters controlling CPU idle time management
described below are only relevant for the *x86* architecture and some of
them affect Intel processors only.
