It should NOT affect kernel samples REnato That's what I figured, but was just checking. :-) I mispoke before, the last time I have this stuff working was with cs 11408 and what I labeled "old profile" (whatever that was...) So I went back and resurrected my cs 11408 xen build and ran three different versions of xenoprof against it: (1) oprofile 0.9.2 + your patch for 0.9.2 (2) oprofile 0.9.1 + your patch r3 for 0.9.1 (3) oprofile 0.9.1 + Rosimildo's old patch to fix image->start and image->end for 64 bit hypervisor (1) and (2) didn't give me any xen or guest kernel samples. (3) worked the way I was expecting things to work (as it had before). So I am guessing that (3) is the old profile I used before. I rebooted to cs 11785 + AMD patches, and retried (3) and it works basically the same as it did for 11408 (whew). I still haven't verified that the xen and kernel guest samples are correct, but at least there are xen, kernel guest, kernel user samples and I'm not getting any with (1) or (2). So I am thinking that the problems I am seeing are related to 64-bit hypervisor and the more recent fixes than Rosimildo's patchset. -- Best Regards, Ray Ray Bryant, Ph.
