[Xen-devel] Latest XenOprofile patch for Oprofile 0.9.1
Attached is the latest version of the patch for oprofile 0.9.1 that enable system wide profiling in Xen. This patch is for Oprofile user level tools since the kernel and xen bits are already included in current xen unstable tree. I am not completely happy with this version and plan to do some more clean up in the future. But since this may take a while I though it would be useful to have a version that works for now. This new version includes support for passive domains. The original patch posted by Xiaowei was for oprofile 0.8.2 and had some problems with hardcoded kernel address ranges. This is now fixed in this latest version. I have done a few tests and it seems to be working fine, but there might be some corner cases that may need fixing. I would appreciate any feedback from users to help clean up any issues that may be remaining. On a related note, there were reports that XenOprofile was not working properly with fully virtualized guests. I believe Tom Woller provided a patch that fixed the problem for SVM AMD cpus but I think the problem is still there for Intel cpus. I would appreciate if someone familiar with Xen VTX support could take a look at Tom patches and provided a similar fix for Intel VT.
