perf vendor events intel: Update rocketlake 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:
- tma_info_bottleneck* metrics, an abstraction or summarization of
the 100+ TMA tree nodes into 12-entry familiar performance metrics.
- Reduce number of events (multiplexing) for tma_info_system_gflops,
tma_info_core_flopc, tma_info_inst_mix_ipflop and tma_ports_utilized_0.
- Fixes for tma_info_bottleneck_mispredictions and
tma_info_bad_spec_branch_misprediction_cost.
- New tma_info_inst_mix_ippause metric.
- tma_serializing_operation is raised to level 3.
- Swapped tma_info_core_ilp (becomes per SMT thread) and
tma_info_pipeline_execute (per physical core).
- tma_nop_instructions and tma_shuffles_256b are lowered to level 4
under tma_other_light_ops_group.
- Reduced number of events when SMT is off.
- Tuned thresholds for tma_info_bottleneck_branching_overhead,
tma_fetch_bandwidth and tma_ports_utilized_3m.
