Jeremy,

I searched Mark Mail for "xenoprof pvops" and found this email from dulloor:

http://markmail.org/search/?q=xenoprof+pvops#query:xenoprof%20pvops+page:1+mid:yyzbymymat3rtivo+state:results

Do you know if dulloor's patches for xenoprof for linux pvops got applied?

I have not looked at Xen+Oprofile, so there's no support in the pvops
kernel as yet.  If someone who's familiar with that stuff could generate
a patch, I'd be happy to include it.
