How to use Px/Cx for power saving?
Hi,
If we want to use ACPI power saving(Cx/Px), how do we use them?
I tried to turn CONFIG_xxxx of cpufreq on with linux-2.6.18-xen.hg,
but I couldn''t turn them on.
Also xenpm said the following error.
# xenpm get-cpuidle-states
Xen cpuidle is not enabled!
# xenpm get-cpufreq-states
Xen cpufreq is not enabled!
What should I do?
If there are some good documents, please tell me.
