...orst I have seen are a couple of "Timer went backwards" error messages but they don''t always show up in the logs. Anything else I should be poking at to figure out why this might be happening and if there are any potential fixes?

Hi, Is there any documentation on enabling hypervisor support for both C and P-state control? On xen-unstable and linux-2.6.18-xen.hg, if I enable cpuidle=1 on the xen command line and then run xenpm, I will get output for C-states (shown below) but it complains that "Xen cpufreq is not enabled!" cpu id : 0 total C-states : 2 idle time(ms) : 73264 C0

Hi, Does Xen provide support for CPU frequency scaling? If there exists such support, from which version they support it? Otherwise what problems do exist in support frequency scaling in Xen?
