Xen devel - Sep 2011 - Whether xen will support intel atom cpu

I have pc with intel atom cpu. 
And When use xen i got the following error: 
"Performance Events : unsupported p6 CPU model 28 no PMU driver, software
events only."
So, i can use suspend to ram but can't use wake up from ram on my pc.
Please, tell me, when xen will support intel atom cpu?
I use xen-unstable (4.2)

What are you using as Dom0? The ACPI suspend code has just been posted
(http://www.gossamer-threads.com/lists/xen/devel/216684?do=post_view_threaded)

so it is _not_ upstream yet. But if you want to try it out, I would suggest you
try:

http://oss.oracle.com/git/?p=kwilk/xen.git;a=shortlog;h=testing

or git://oss.oracle.com/git/kwilk/xen.git testing

which has the patches for that in it.

It works fine for me.

This message has absolutely nothing to do with support for ACPI S3 (suspend
to ram).

Agreed, Try installing vanilla linux on that unit and see if S3 works..

I am not really sure what you are saying. The issue he is hitting
is that he is trying to use ACPI S3 with Xen. But ACPI S3 won''t work
with Xen b/c the patches to enable that are not upstream yet.

But they are in the #testing branch.

well, Maxim tried S3 with Xen on this atom system it did not resume, so I
suggested trying vanilla linux on the same system. If Linux works then issue
could be with xen/dom-0 else something native with the system.
