Yes, ARC can certainly use this infrastructure. Our hardware conditions are actually 1-8 char strings. So using raw events requires me to first convert the string to ASCII. > > I am also assuming that if the header files like power8-events.h are > easily readable, we don't need the JSON files anymore? > > TODO: > - Maybe translate event names to lower-case? > - Allow perf to process event descriptions (need Andi Kleen's patch) > > > Sukadev Bhattiprolu (4): > perf: Create a table of Power7 PMU events > perf: Create a table of Power8 PMU events > perf/powerpc: Move mfspr and friends to header file > perf: Create aliases for Power PMU events > > tools/perf/arch/powerpc/util/Build | 2 +- > tools/perf/arch/powerpc/util/header.c | 9 +- > tools/perf/arch/powerpc/util/header.h | 9 + > tools/perf/arch/powerpc/util/pmu-events.c | 52 + > tools/perf/arch/powerpc/util/pmu-events.h | 17 + > tools/perf/arch/powerpc/util/power7-events.h | 3315 +++++++++++++ > tools/perf/arch/powerpc/util/power8-events.h | 6408 > ++++++++++++++++++++++++++ > tools/perf/util/pmu.c | 77 + > tools/perf/util/pmu.h | 10 + > 9 files changed, 9890 insertions(+), 9 deletions(-) > create mode 100644 tools/perf/arch/powerpc/util/header.h > create mode 100644 tools/perf/arch/powerpc/util/pmu-events.c > create mode 100644 tools/perf/arch/powerpc/util/pmu-events.h > create mode 100644 tools/perf/arch/powerpc/util/power7-events.h > create mode 100644 tools/perf/arch/powerpc/util/power8-events.h > _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
