Re: [Xen-devel] Re: [Xen-users] xen 4.0 and cpufreq with pvops dom0 kernel

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Xen needs a suitably configured odm0 kernel to push cpufreq info down into
it. My guess would be that the new dom0 kernel that was installed is missing
the relevant support, or it is not configured into the build.
