we don't support cpufreq=dom0-kernel. none of the native kernel cpufreq utilities are Xen-enabled. I'm not certain xenpm is fully functional in 3.3.x (and specifically for AMD CPUs). the patch you mention above should, afaict, affect Intel CPUs only.
strikes on all counts :-/
using cpufreq=xen *does* have an effect on Fam10 CPUs as one can observe by watching the /proc/cpuinfo output. If that's not the case for you, please provide Xen+kernel boot output (Xen started with loglvl=all guest_loglvl=all).
you're correct, it _is_ the case, as can be seen here in /proc/cpuinfo ... cat /proc/cpuinfo | egrep -i "processor|MHz" processor : 0 model name : AMD Phenom(tm) II X4 920 Processor cpu MHz : 800.000 power management: ts ttp tm stc 100mhzsteps hwpstate processor : 1 model name : AMD Phenom(tm) II X4 920 Processor cpu MHz : 4294967.294 power management: ts ttp tm stc 100mhzsteps hwpstate processor : 2 model name : AMD Phenom(tm) II X4 920 Processor cpu MHz : 4294967.294 power management: ts ttp tm stc 100mhzsteps hwpstate processor : 3 model name : AMD Phenom(tm) II X4 920 Processor cpu MHz : 4294967.294 power management: ts ttp tm stc 100mhzsteps hwpstate still, @ xenpm get-scaling-governor Xen cpuidle is not enabled!
