Hi A common case for KVM test programs is that the guest object code can be found in the hypervisor process (i.e. the test program running on the host). Add support for that. For some more details refer the 3rd patch "perf tools: Add guest_code support" For an example, see the last patch "perf intel-pt: Add guest_code support" For more information about Perf tools support for Intel® Processor Trace refer: https://perf.wiki.kernel.org/index.php/Perf_tools_support_for_Intel%C2%AE_Processor_Trace Adrian Hunter (6): perf tools: Add machine to machines back pointer perf tools: Factor out thread__set_guest_comm() perf tools: Add guest_code support perf script: Add guest_code support perf kvm report: Add guest_code support perf intel-pt: Add guest_code support tools/perf/Documentation/perf-intel-pt.txt | 67 ++++++++++++++++++++++++ tools/perf/Documentation/perf-kvm.txt | 3 ++ tools/perf/Documentation/perf-script.txt | 4 ++ tools/perf/builtin-kvm.c | 2 + tools/perf/builtin-script.c | 5 +- tools/perf/util/event.c | 7 ++- tools/perf/util/intel-pt.c | 20 ++++++- tools/perf/util/machine.c | 84 ++++++++++++++++++++++++++++-- tools/perf/util/machine.h | 4 ++ tools/perf/util/session.c | 7 +++ tools/perf/util/symbol_conf.h | 3 +- 11 files changed, 197 insertions(+), 9 deletions(-) Regards Adrian
