This changes enables future changes to c2c on a system with SPE where lines that are shared among multiple cores show up in perf c2c output. Changes in v6: * Drop changes to c2c command which will come from Leo Yan Changes in v5: * Add a new snooping type to disambiguate cache-to-cache transfers where we don't know if the data is clean or dirty. * Set snoop flags on all the data-source cases * Special case stores as we have no information on them Changes in v4: * Bring-in the kernel's arch/arm64/include/asm/cputype.h into tools/ * Add neoverse-v1 to the neoverse cores list Ali Saidi (4): tools: arm64: Import cputype.h perf arm-spe: Use SPE data source for neoverse cores perf mem: Support mem_lvl_num in c2c command perf mem: Support HITM for when mem_lvl_num is any tools/arch/arm64/include/asm/cputype.h | 258 ++++++++++++++++++ .../util/arm-spe-decoder/arm-spe-decoder.c | 1 + .../util/arm-spe-decoder/arm-spe-decoder.h | 12 + tools/perf/util/arm-spe.c | 110 +++++++- tools/perf/util/mem-events.c | 20 +- 5 files changed, 383 insertions(+), 18 deletions(-) create mode 100644 tools/arch/arm64/include/asm/cputype.h
