This patchset enables "perf kvm stat" on powerpc. The first patch enables perf kvm stat record and report to report kvm exits. "record" enables recording of the tracepoints: kvm_hv:kvm_guest_enter and kvm_hv:kvm_guest_exit in the first patch and kvm_hv:kvm_hcall_enter and kvm_hv:kvm_hcall_exit in the second patch. This command can be used to record kvm events on the host: # perf kvm stat record -a To report the kvm guest related exit events, use: # perf kvm stat report or # perf kvm stat report --event=vmexit This should show the exit events along with the exit reasons. The second patch in this series adds support to show the hcall events too with: # perf kvm stat report --event=syscall --- Hemant Kumar (1): perf/kvm: perf-kvm-stat to report syscalls Srikar Dronamraju (1): perf/kvm: Enable perf-kvm-stat record/report on powerpc arch/powerpc/include/asm/hvcall.h | 120 ------------------------- arch/powerpc/include/uapi/asm/hcall_codes.h | 123 ++++++++++++++++++++++++++ arch/powerpc/include/uapi/asm/kvm_perf.h | 19 ++++ arch/powerpc/include/uapi/asm/trace_book3s.h | 33 +++++++ arch/powerpc/include/uapi/asm/trace_hcall.h | 122 ++++++++++++++++++++++++++ arch/powerpc/kvm/trace_book3s.h | 32 ------- arch/powerpc/kvm/trace_hv.h | 119 ------------------------- arch/powerpc/kvm/trace_pr.h | 2 tools/perf/arch/powerpc/Makefile | 1 tools/perf/arch/powerpc/util/Build | 1 tools/perf/arch/powerpc/util/kvm-stat.c | 94 ++++++++++++++++++++ 11 files changed, 398 insertions(+), 268 deletions(-) create mode 100644 arch/powerpc/include/uapi/asm/hcall_codes.h create mode 100644 arch/powerpc/include/uapi/asm/kvm_perf.h create mode 100644 arch/powerpc/include/uapi/asm/trace_book3s.h create mode 100644 arch/powerpc/include/uapi/asm/trace_hcall.h delete mode 100644 arch/powerpc/kvm/trace_book3s.h create mode 100644 tools/perf/arch/powerpc/util/kvm-stat.c -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
