We could then have a paravirtual cpufreq driver added to Linux. This hasthe advantage that we have less new per-cpu-type code to maintain in Xen (we can more easily sync with cpufreq changes in Linux) but it does mean we change more Linux code and we'd want to be a bit careful not to makethe hypercall interface too Linux specific (or too x86 specific).Has this something to do with the private mail I sent to Keir Fraser? I told him that the powernow-k8 support in dom0 seems to work, while in domUs not. Second was that the shown Bogomips under /proc/cpuinfo never changes from ~4000, even when the CPU was @ 800. That's a quite separate issue. The 'stale' frequency info in domU is harmless. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
