Cache home agent (CHA) events were setting the low rather than high

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.

Update the skylakex metrics and events using the new tooling from:
https://github.com/intel/perfmon
The metrics are unchanged but the formulas differ due to parentheses,
use of exponents and removal of redundant operations like "* 1". The
order of metrics varies as TMA metrics are first converted and then
removed if perfmon versions are found. The events are updated with
fixes to uncore events and improved descriptions. uncore-other.json
changes due to events now being sorted. The formatting changes
increase consistency across the json files.

Updates include:
- Removal of ScaleUnit from uncore events by Zhengjun Xing

- 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.
- Latest metrics from: https://github.com/intel/perfmon-metrics

Ian reports an issue that the metric DRAM_BW_Use often remains 0.
The metric expression for DRAM_BW_Use on CLX/SKX:
"( 64 * ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) / 1000000000 ) / duration_time"
The counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/
are scaled up by 64, that is to turn a count of cache lines into bytes,
the count is then divided by 1000000000 to give GB.
However, the counts of uncore_imc/cas_count_read/ and
uncore_imc/cas_count_write/ have been scaled yet.
The scale values are from sysfs, such as
/sys/devices/uncore_imc_0/events/cas_count_read.scale.
It's 6.103515625e-5 (64 / 1024.0 / 1024.0).
So if we use original metric expression, the result is not correct.
But the difficulty is, for SKL client, the counts are not scaled.
The metric expression for DRAM_BW_Use on SKL:
"64 * ( arb@event\\=0x81\\,umask\\=0x1@ + arb@event\\=0x84\\,umask\\=0x1@ ) / 1000000 / duration_time / 1000"
root@kbl-ppc:~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
190 arb/event=0x84,umask=0x1/ # 1.86 DRAM_BW_Use
29,093,178 arb/event=0x81,umask=0x1/
1,000,703,287 ns duration_time
1.000703287 seconds time elapsed
The result is expected.
So the easy way is just change the metric expression for CLX/SKX.
This patch changes the metric expression to:
"( ( ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) * 1048576 ) / 1000000000 ) / duration_time"
1048576 = 1024 * 1024.
Before (tested on CLX):
root@lkp-csl-2sp5 ~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
765.35 MiB uncore_imc/cas_count_read/ # 0.00 DRAM_BW_Use
5.42 MiB uncore_imc/cas_count_write/
1001515088 ns duration_time
1.001515088 seconds time elapsed
After:
root@lkp-csl-2sp5 ~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
767.95 MiB uncore_imc/cas_count_read/ # 0.80 DRAM_BW_Use
5.02 MiB uncore_imc/cas_count_write/
1001900010 ns duration_time

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

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.

Go over the tools/ files that are maintained in Arnaldo's tree and
fix common typos: half of them were in comments, the other half
in JSON files.
( Care should be taken not to re-import these typos in the future,
if the JSON files get updated by the vendor without fixing the typos. )
No change in functionality intended.
Committer notes:
This was split from a larger patch as there are code that is,
additionally, maintained outside the kernel tree, so to ease cherry
picking and/or backporting, split this into multiple patches.

This is a much fuller list than with earlier uncores, including

include the "experimential" events. The previous
high level metric (LLC_* etc.) are still available when applicable.
C state power events are not included at this point.
