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:
