When restricting jevents generated json lookup code with JEVENTS_MODEL a list of models must be provided. Some builds don't know model names but know cpuids. Add a command that can convert a cpuid to a model using mapfile.csv files. This can be used with JEVENTS_MODEL like: $ make JEVENTS_MODEL=`./pmu-events/models.py x86 'GenuineIntel-6-8D-1,AuthenticAMD-26-1' pmu-events/arch/` Committer testing: $ tools/perf/pmu-events/models.py x86 'GenuineIntel-6-8D-1,AuthenticAMD-26-1' tools/perf/pmu-events/arch/ tigerlake,amdzen5 $ perf stat -v sleep 1 |& head -1 Using CPUID GenuineIntel-6-B7-1 $ tools/perf/pmu-events/models.py x86 'GenuineIntel-6-B7-1' tools/perf/pmu-events/arch/ alderlake $ Signed-off-by: Ian Rogers <irogers@google.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20240904044351.712080-1-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
