Hello Everybody:

I know that Xen-3.3.0 supports CPU frequency scaling in the userspace, and hypercall interface is created for such purpose (tools/libxc/xc_pm.c).

But how can I use this interface in the userspace of D0? Should I have to write some programs or scripts? Is there any tools to use this function?

Thank you very much!
