Subject: [PATCH 0/9][v5] powerpc/perf: Export memory hierarchy level in Power7/8.
Power7 and Power8 processors save the memory hierarchy level (eg: L2, L3) from which a load or store instruction was satisfied. Export this hierarchy information to the user via the perf_mem_data_src object. Thanks to input from Stephane Eranian, Michael Ellerman, Michael Neuling and Anshuman Khandual. Sukadev Bhattiprolu (9): powerpc/perf: Rename Power8 macros to start with PME powerpc/perf: Export Power8 generic events in sysfs powerpc/perf: Add Power8 event PM_MRK_GRP_CMPL to sysfs. powerpc: Rename branch_opcode() to instr_opcode() powerpc: implement is_instr_load_store(). powerpc/perf: Define big-endian version of perf_mem_data_src powerpc/perf: Export Power8 memory hierarchy info to user space. powerpc/perf: Export Power7 memory hierarchy info to user space. powerpc/perf: Update perf-mem man page for Power arch/powerpc/include/asm/code-patching.h | 1 + arch/powerpc/include/asm/perf_event_server.h | 2 + arch/powerpc/lib/code-patching.c | 96 ++++++++++++++++++++++- arch/powerpc/perf/core-book3s.c | 11 +++ arch/powerpc/perf/power7-pmu.c | 94 +++++++++++++++++++++++ arch/powerpc/perf/power8-pmu.c | 105 +++++++++++++++++++++++--- include/uapi/linux/perf_event.h | 58 ++++++++++++++ tools/perf/Documentation/perf-mem.txt | 11 +++ tools/perf/util/include/asm/byteorder.h | 1 + 9 files changed, 364 insertions(+), 15 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
