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.
- 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.

Some metric groups have metrics that don't have fully overlapping
events, meaning that the group's events become unique event groups that
may need to multiplex with each other. This can be particularly
unfortunate when the groups wouldn't need to multiplex because there are
sufficient hardware counters.
Add a flag so that if recording a metric group then the metrics within
the group needn't use groups for their events. The flag is added to
Intel TopdownL1 and TopdownL2 metrics.

with updates at:

Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- _SMT suffix metrics are dropped as the #SMT_On and #EBS_Mode are
correctly expanded in the single main metric.
- Addition of all 6 levels of TMA metrics. Child metrics are placed
in a group named after their parent allowing children of a metric
to be easily measured using the metric name with a _group suffix.
- ## and ##? operators are correctly expanded.
- The locate-with column is added to the long description describing
a sampling event.
- Metrics are written in terms of other metrics to reduce the
expression size and increase readability.

The kernel utilization metric does multiplexing currently and is somewhat
unreliable. The problem is that it uses two instances of the fixed counter,
and the kernel has to multipleplex which causes errors. So should use
CPU_CLK_UNHALTED.THREAD instead.
Before:
# perf stat -M Kernel_Utilization -- sleep 1
Performance counter stats for 'sleep 1':
1,419,425 cpu_clk_unhalted.ref_tsc:k
<not counted> cpu_clk_unhalted.ref_tsc (0.00%)
After:
# perf stat -M Kernel_Utilization -- sleep 1
Performance counter stats for 'sleep 1':
746,688 cpu_clk_unhalted.thread:k # 0.7 Kernel_Utilization
1,088,348 cpu_clk_unhalted.thread

New Metrics:
- DSB_Switches: fraction of cycles CPU was stalled due to switches from DSB to MITE pipeline [all]
- L2_Evictions_{Silent|NonSilent}_PKI: L2 {silent|non silent} ecivtions rate per Kilo instruction [SKX+]
- IpFarBranch - Instructions per Far Branch
Other Enhancements & fixes:
- KBLR/CFL & CLX move to separate columns (no column sharing via if #model)
- Re-organized/renamed Metric Group

Update all the Intel JSON metrics from Ahmad Yasin's TMAM 3.5
for Intel big core from Sandy Bridge to Cascade Lake.
This has many improvements and new metircs
- New TopDownL1_SMT group that provides a per SMT thread version
of --topdown that does not require -a anymore. The drawback is
increased multiplexing though since L1 TopDown does not fit into
4 generic counters anymore.
- Added SMT aware versions of other metrics
- Split SMT aware metrics into separate metrics to avoid
unnecessary event collections
- New metrics for better branch analysis:
Estimated Branch_Mispredict_Costs, Instructions per taken Branch,
Branch Instructions per Taken Branch, etc.
- Instruction mix metrics:
Instructions per load, Instructions per store, Instructions per Branch,
Instructions per Call
- New Cache metrics:
Bandwidth to L1/L2/L3 caches. L1/L2/L3 misses per kilo instructions.
memory level parallelism
- New memory controller metrics:
Normalized memory bandwidth in interval mode, Average memory latency,
Average number of parallel read requests,
- 3DXP persistent memory metrics for Cascade Lake:
3dxp read latency, 3dxp read/write bandwidth
- Some other useful metrics like Instruction Level Parallelism,
- Various other improvements.
Not all metrics are available on all CPUs. Skylake has best coverage.
