Will Xenoprof patches for oprofile 0.9.3 (to enable passive domain profiling) are now available at http://xenoprof.sourceforge.net. A required patch for the kernel is also available at the same location. I think the kernel patch should NOT be included into the public Xen tree at this time, as this will break compatibility with oprofile 0.9.2 that users are currently using. I think it is better to have users wanting to upgrade to oprofile 0.9.3 to apply an extra patch to the kernel rather than breaking compatibility for all current users. I think we should wait until Xen dom0 support gets into mainline linux to do that (or at least until xenoprof patches are included in an official oprofile release).
