Description of problem: We really should have support for Xenoprof in the RHEL-4 PV kernels. I have a preliminary patch, but it needs much review and testing since it touches some core oprofile code.
Created attachment 159969 [details] Very rough first patch for xenoprof support This is my rough draft for xenoprof support for RHEL-4 PV. It's been compile and boot tested, but *not* tested to work for xenoprof yet. It also contains some changes to core oprofile code, so I need to go through that with a fine-toothed comb and make sure things aren't being broken. All in all, definitely not ready yet, but a work in progress. Chris Lalancette
