Sample mode RLS updates Sampled Instruction Event Register [SIER] bits with memory hierarchy information for a cache reload. Patchset exports the hierarchy information to the user via the perf_mem_data_src object from SIER. Patchset is a rebase of the work posted previously with minor updates to it. https://lkml.org/lkml/2015/6/11/92 Madhavan Srinivasan (6): powerpc/perf: Define big-endian version of perf_mem_data_src powerpc/perf: Export memory hierarchy info to user space powerpc/perf: Support to export MMCRA[TEC*] field to userspace powerpc/perf: Support to export SIERs bit in Power8 powerpc/perf: Support to export SIERs bit in Power9 powerpc/perf: Add Power8 mem_access event to sysfs arch/powerpc/include/asm/perf_event_server.h | 3 + arch/powerpc/perf/core-book3s.c | 8 +++ arch/powerpc/perf/isa207-common.c | 86 ++++++++++++++++++++++++++++ arch/powerpc/perf/isa207-common.h | 26 ++++++++- arch/powerpc/perf/power8-events-list.h | 6 ++ arch/powerpc/perf/power8-pmu.c | 4 ++ arch/powerpc/perf/power9-pmu.c | 2 + include/uapi/linux/perf_event.h | 16 ++++++ tools/include/uapi/linux/perf_event.h | 16 ++++++ 9 files changed, 166 insertions(+), 1 deletion(-) -- 2.7.4
