Hi, list: I am trying to do some profile work on Xen 4.0 with pvops kernel on an AMD machine (equipped with AMD 'Istanbul' Family 10h processors). I have found the dulloor's xenoprof patch for pvops kernel. But it does not contain supports for IBS. The only IBS support for xenoprofile posted by Wei Wang seems to be for 2.6.18-dom0 kernel. So is there any support for pvops kernel to use IBS on AMD? Another question is when i am using normal profiling event (such as L2_MISS) on my AMD machine, it seems that it does not generate interrupt when the performance counter overflows. Is there any problem with AMD processor or the xenoprofile patch? Thanks, Best regards _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
