Re: [Xen-users] powernow-k8

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Hi Imre,

I'm afraid it's not possible to use Powernow with 3.0.2 at all.  Nor is it 
possible to use other CPU power saving technologies.

This is because supporting this is not quite so simple under Xen.  You can't 
just load a driver into dom0 Linux because Xen needs to know about PowerNow 
too.  Extra code would be required in Xen to support it.

Someone from AMD has been working on this extra code and I believe initial 
support for Powernow is going to be in the Xen 3.2 release and is currently 
in the xen-unstable tree.

Cheers,
Mark
