Re: [Xen-ia64-devel] [PATCH 0/3] IA64: add cpufreq support

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi, Yu.
Thnaks for updating the patches while you're off.

I applied your patch with some style fixes and tried xenpm.
(I attached the fixed patch. Please confirm I didn't breake them.)
Then I got the followings. (NOTE: I added cpufreq=xen to xen boot option)
Doesn't xenpm work on ia64? Or is there another way to test them?

# xenpm 
Xen cpuidle is not enabled!
failed to get max P-state

thanks,
