Hi, Mike,

Are there any BIOS options in your box related with C-states or P-states? These may be disabled.

Or can you try the native Linux first to make sure you can see the PM effect?

Further, if you can rebuild Xen yourself, please turn on the C/P state debug flag ( e.g. uncomment/*#define DEBUG_PM_CX*/ in cpu_idle.c) , and repost the serial log for more detail info.

Jimmy

  To: Wei, Gang; +Cc: xen-devel, Keir Fraser

The BIOS has the following options, both of which are enabled:
- Intel Speed Step
- Deep C-State Support

As reported by /proc/cpuinfo the cpu speed does vary using a native
Linux kernel.

Sorry but I am not in a position to do my own build at the moment.  I
may be able to try it next week.

Thanks

Mike

Can you try with removing "dom0_max_vcpus=1" from the grub line? I suspect this is a dom0 kernel issue. The upstream 2.6.18 xen-linux kernel works well as dom0 kernel with PM. I am not sure about Centos 5.3 kernel.

May be the Centos kernel does not have something that is required.  What

Is there a way for me to tell if the Centos kernel has those
modifications?  A kernel config option or something?

The xenpm wiki page shows an extract for xm dmesg, but there is nothing
like that in my xm dmesg output.  Is it possible that there is something
missing from the gitco Xen build?
