Attached patch is what we have been using internally to allow HVM guest profiling on 64bit hv with 32bit hvm guest. Code generated by Rosimildo. This patch is experimental and not ready for inclusion into any repo, but might help with the next set of patches for xenoprofile support. This patch has oprofile, SVM, VT and HVM modifications all rolled into one inclusive patch file. For SVM, if you modify opd_kernel.c image start/end addresses in oprofile 0.9.1 then 64bit samples seem to work. VT does not seem to work with attached patch, but we haven't spent time debugging why. Mods: 1) move SVM global interrupt to vmexit handler 2) add VGCF_hvm_guest_nmi flag to guest context to distinguish nmi occuring in guest rather than in host 3) oprofile model files modified to use the new VGCF_hvm_guest_nmi flag to determine a bit more properly the mode Thanks Tom Attachment:
