[DOCS] cpufreq/cpuidle docs?

[DOCS] cpufreq/cpuidle docs?

[Sven Köhler]

Hi,

I would like to RTFM, but I can't find any docs about cpufreq and/or
cpuidle parameters. There are some of them - I occasionally read about
the. (cpufreq=xen cpuidle=force etc.) but is there a list somewhere?

I would like to finetune cpufreq and cpuidle. For example, I would like
to set the default governor to ondemand and I would like to limit
cpuidle to certain sleep states.


Regards,
  Sven

Somebody already pointed me to the page
	http://wiki.xensource.com/xenwiki/xenpm

If I see it correctly, then this document describes how to use xenpm.
Sorry, but that is not what I asked for, maybe because I didn't describe
it well. This page does not describe the boot parameters like
cpufreq=xen or cpuidle=force.

I could set the CPU governor to ondemand using xenpm. But if
it's possible, then I would like to add a boot parameter in my
grub.conf. But any list of xen boot parameters that I find on the net
doesn't mention any cpufreq or cpuidle parameters.

Please read the document, it does explain exactly what you are asking for.

Also please do not post questions like this to xen-devel, xen-users is
the appropriate list for general questions.
