oprofile and xen

Hello,

I was wondering if xen currently works well with oprofile. I saw some patch
out there put together by an HP engineer but it does not work with the
current version of the code. Does anyone know how much change there has been
in the code and whether it would take much effort to modify the patch?

Thanks,

Carter

As I know, you mean xenoprof, right? 

 

In my experience, it works with my xen4.0.1 and 2.6.18 linux dom0 kernel.
(intel xeon)

 

I don't know which parts of xen source code are modified, 

but I guess the most parts related with xenoprof are not modified. 

 

Did you test the recent xenoprof on the recent xen and dom0? 

 

Please post your result if it is possible.

 

Thanks.
