perf vendor events intel: Update broadwellde 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 <[email protected]> Reviewed-by: Kan Liang <[email protected]> Cc: Stephane Eranian <[email protected]> Cc: Caleb Biggers <[email protected]> Cc: Edward Baker <[email protected]> Cc: Perry Taylor <[email protected]> Cc: Samantha Alt <[email protected]> Cc: Weilin Wang <[email protected]> Signed-off-by: Namhyung Kim <[email protected]> Link: https://lore.kernel.org/r/[email protected]
