This removes the need to duplicate the whole set of JSONs when only the topdown metrics are different between N2 and V2. The CPU ID comparison function still needs to change so that the new literal can compare on versions, but now no change is needed to mapfile or the PMU event generation code because we still only support one set of JSONs per CPU. [1]: https://lore.kernel.org/lkml/20230711100218.1651995-1-james.clark@arm.com/ ------ Changes since v3: * Instead of duplicating all the metrics, add a new expression literal that can be used to share the same metrics between N2 and V2 * Move tests to arch/arm64/tests * Remove changes from jevents.py and mapfile.csv Changes since v2: * version -> variant in second commit message * Add a bit more detail about version matching in the second commit message * Update the comments in pmu-events/arch/arm64/mapfile.csv to say that variant and revision fields are now used * Increase the CC list Changes since v1: * Split last change into two so it doesn't hit the mailing list size limit James Clark (6): perf: cs-etm: Don't duplicate FIELD_GET() perf arm64: Allow version comparisons of CPU IDs perf test: Add a test for the new Arm CPU ID comparison behavior perf vendor events arm64: Update scale units and descriptions of common topdown metrics perf vendor events arm64: Update stall_slot workaround for N2 r0p3 perf vendor events arm64: Update N2 and V2 metrics and events using Arm telemetry repo tools/perf/arch/arm64/include/arch-tests.h | 3 + tools/perf/arch/arm64/tests/Build | 1 + tools/perf/arch/arm64/tests/arch-tests.c | 4 + tools/perf/arch/arm64/tests/cpuid-match.c | 38 ++ tools/perf/arch/arm64/util/header.c | 64 ++- tools/perf/arch/arm64/util/pmu.c | 21 + .../arch/arm64/arm/neoverse-n2-v2/branch.json | 8 - .../arch/arm64/arm/neoverse-n2-v2/bus.json | 18 +- .../arch/arm64/arm/neoverse-n2-v2/cache.json | 155 -------- .../arm64/arm/neoverse-n2-v2/exception.json | 45 ++- .../arm/neoverse-n2-v2/fp_operation.json | 22 ++ .../arm64/arm/neoverse-n2-v2/general.json | 10 + .../arm64/arm/neoverse-n2-v2/instruction.json | 143 ------- .../arm64/arm/neoverse-n2-v2/l1d_cache.json | 54 +++ .../arm64/arm/neoverse-n2-v2/l1i_cache.json | 14 + .../arm64/arm/neoverse-n2-v2/l2_cache.json | 50 +++ .../arm64/arm/neoverse-n2-v2/l3_cache.json | 22 ++ .../arm64/arm/neoverse-n2-v2/ll_cache.json | 10 + .../arch/arm64/arm/neoverse-n2-v2/memory.json | 39 +- .../arm64/arm/neoverse-n2-v2/metrics.json | 365 ++++++++++-------- .../arm64/arm/neoverse-n2-v2/pipeline.json | 23 -- .../arm64/arm/neoverse-n2-v2/retired.json | 30 ++ .../arch/arm64/arm/neoverse-n2-v2/spe.json | 12 +- .../arm/neoverse-n2-v2/spec_operation.json | 110 ++++++ .../arch/arm64/arm/neoverse-n2-v2/stall.json | 30 ++ .../arch/arm64/arm/neoverse-n2-v2/sve.json | 50 +++ .../arch/arm64/arm/neoverse-n2-v2/tlb.json | 66 ++++ .../arch/arm64/arm/neoverse-n2-v2/trace.json | 27 +- tools/perf/pmu-events/arch/arm64/sbsa.json | 24 +- tools/perf/util/cs-etm.c | 14 +- tools/perf/util/expr.c | 4 + tools/perf/util/pmu.c | 6 + tools/perf/util/pmu.h | 1 + 33 files changed, 894 insertions(+), 589 deletions(-) create mode 100644 tools/perf/arch/arm64/tests/cpuid-match.c delete mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/branch.json delete mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/cache.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/fp_operation.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/general.json delete mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/instruction.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/l1d_cache.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/l1i_cache.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/l2_cache.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/l3_cache.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/ll_cache.json delete mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/pipeline.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/retired.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/spec_operation.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/stall.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/sve.json create mode 100644 tools/perf/pmu-events/arch/arm64/arm/neoverse-n2-v2/tlb.json
