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.

Best Regards,
