[Xen-users] cpu frequency scaling in xen 3.3.1

[Florian Gleixner <flo@xxxxxxxxx>]

Hi,

i read the xenpm wiki page, but i cannot use the "p-states". xenpm shows:

xenpm
cpu id               : 0
total C-states       : 2
idle time(ms)        : 1776034
C0                   : transition [00000000000000000000]
                       residency  [00000000000000000000 ms]
C1                   : transition [00000000000000260278]
                       residency  [00000000000000000000 ms]

cpu id               : 1
total C-states       : 0
idle time(ms)        : 1771123

[CPU0] failed to get P-states statistics information
[CPU1] failed to get P-states statistics information

/proc/cpuinfo shows:
model name      : AMD Athlon(tm) Dual Core Processor 5050e

without xen i can scale the frequency perfectly. Are p-states for this
CPU model unsupported? My grub line is:
    kernel /xen.gz cpufreq=xen cpuidle
...

Thanks for the help!

Florian
