perf vendor events intel: Update broadwell TMA metrics to 4.7
Top-Down Microarchitecture Analysis (TMA) metrics simplify cycle-accounting using microarchitecture-abstracted metrics organized in one hierarchy. This update is from version 4.5 to 4.7. The update includes: - Reduce number of events (multiplexing) for tma_info_system_gflops, tma_info_core_flopc and tma_info_inst_mix_ipflop. - Removal of tma_info_bad_spec_branch_misprediction_cost. - Swapped tma_info_core_ilp (becomes per SMT thread) and tma_info_pipeline_execute (per physical core). - Tuned thresholds for tma_fetch_bandwidth and tma_ports_utilized_3m. The update came from: https://github.com/intel/perfmon/pull/140 https://github.com/intel/perfmon/pull/138 Running the script: https://github.com/intel/perfmon/blob/main/scripts/create_perf_json.py Signed-off-by: Ian Rogers <irogers@google.com> Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Cc: Stephane Eranian <eranian@google.com> Cc: Caleb Biggers <caleb.biggers@intel.com> Cc: Edward Baker <edward.baker@intel.com> Cc: Perry Taylor <perry.taylor@intel.com> Cc: Samantha Alt <samantha.alt@intel.com> Cc: Weilin Wang <weilin.wang@intel.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240214011820.644458-15-irogers@google.com
