[lee <lee@xxxxxxxxxxx>]

Hi,

root@heimdall:~# xenpm get-cpufreq-states all
root@heimdall:~# xenpm get-cpufreq-para all
[CPU0] failed to get cpufreq parameter
[CPU1] failed to get cpufreq parameter

'xenpm get-cpuidle-states all' gives some output and says "total C-states :
2".  The CPUs are L5420s.

Again we must be afraid of speaking of daemons for fear that daemons
might swallow us.  Finally, this fear has become reasonable.
