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. |
