perf vendor events intel: Update broadwellx 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

perf vendor events intel: Add metricgroup descriptions for all models
Add metric group descriptions created by: https://github.com/intel/perfmon/blob/main/scripts/create_perf_json.py The descriptions add some additional detail in perf list.
Committer notes:
Removed unrelated changes to tools/perf/pmu-events/arch/x86/mapfile.csv that removed AMD mappings and ended up breaking the build with things like:
