So, I'm now working with an oprofile 0.9.2 plus your patch oprofile-0.9.2-xen.patch from the HP open source website. The particular project we are working on requires us to obtain profiles for the HVM guest kernel. Unfortunately, my first few tries at this have been unsuccessful (I get lots of "lost kernel sample" messages in the oprofiled.log and no reported samples for the guest kernel. :-( ). So I guess my guestion to you is, do you have access to a VT or AMD V enabled platform that you can test stuff on? (I'd like to find a collegue to work with on this problem if at all possible.) I have dedicated VT and AMD platforms for my use, so if you have a VT platorm, we can get stuff to work correctly there first and then I can work with Tom et al to get the AMD V versions to work. -- Ray Bryant AMD Performance Labs Austin, Tx 512-602-0038 (o) 512-507-7807 (c)
