RE: RE: How can I scaling CPU frequency in Xen-3.3.0?
Currently, Xen only has ondemand governor, and the CPU freqquency is set
automatically by xen according to the workload. The userspace governor is not
available yet. so there is no such tool to set frequency
Technically speaking, it is not hard to add userspace governor to xen,
since the governor interface is well defined as linux kernel. and adding more
governors to Xen is in our mind, but we are not sure if it is necessary. Inputs
from community are welcome.

Hello, Yu, Ke:
Thank you very much for your help!
With this patch I can get the CPU PM info expediently.
And I want to set the frequency of
physical CPU in the xen system, just like userspace governor in Linux proc
filesystem. Is there any tools?
