Some TMA metrics have double if expressions like:
( CPU_CLK_UNHALTED.THREAD / 2 ) * ( 1 + CPU_CLK_UNHALTED.ONE_THREAD_ACTIVE / CPU_CLK_UNHALTED.REF_XCLK ) ) if #core_wide < 1 else ( CPU_CLK_UNHALTED.THREAD_ANY / 2 ) if #SMT_on else CPU_CLK_UNHALTED.THREAD
This currently fails to parse as the left hand side if expression needs
to be in parentheses. By allowing the if expression to have a right hand
side that is an if expression we can parse the expression above, with
left to right evaluation order that matches languages like Python.

jevents.py no longer lowercases metrics and altering the case can cause
hashmap lookups to fail, so remove.

Counts are scaled prior to going into saved_value, reverse the scaling
so that metrics don't double scale values.

I've not been able to reproduce this. I've tried:
{
"MetricName": "IanTest",
"MetricExpr": "uncore_imc@cas_count_read@ * 6.103515625e-5 +
uncore_imc@cas_count_write@ * 6.103515625e-5"
}
where it scales the two counters and sums them. I see:
$ perf stat -M IanTest -a sleep 1
Performance counter stats for 'system wide':
298.70 MiB uncore_imc/cas_count_write/ # 721.00
IanTest
429.64 MiB uncore_imc/cas_count_read/
1.004877710 seconds time elapsed
So the metric's value nearly matches the sum. If the scaled values had
been used the sum would have been something like 0.044454345703124995.
From the code, this is the only place a metric's "ID" (event/counter)
is associated with a value, so I would be confused if there were a
code path where reversing the scaling wasn't happening.
Thanks,
Ian

Events remain at v1.28, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Removal of ScaleUnit from uncore events by Zhengjun Xing
<zhengjun.xing@linux.intel.com>.
- 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.
Tested on a skylakex manually and with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
93: perf all metricgroups test : Ok
94: perf all metrics test : Skip
95: perf all PMU test : Ok

Assists are long sequences of uops that are required in certain corner-cases for operations that cannot be handled natively by the execution pipeline. For example; when working with very small floating point values (so-called Denormals); the FP units are not set up to perform these operations natively. Instead; a sequence of instructions to perform the computation on the Denormals is injected into the pipeline. Since these microcode sequences might be dozens of uops long; Assists can be extremely deleterious to performance and they can be avoided in many cases. Sample with: OTHER_ASSISTS.ANY"

Events are updated to v1.15, the core metrics are based on TMA 4.4
full and the atom metrics on E-core TMA 2.2.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

I think I should send a v2. I can add this then. Other things for v2 are:
- this week there will likely be an update to [1] which is implicitly
integrated here.
- the topdown metrics are all percentages but are currently values
zero to 1. It is straightforward to add a ScaleUnit of 100% to them
all.
- eyeballing topdown event metrics like:
{
"BriefDescription": "This category represents fraction of slots
utilized by useful work i.e. issued uops that eventually get retired",
"MetricExpr": "topdown\\-retiring / (topdown\\-fe\\-bound +
topdown\\-bad\\-spec + topdown\\-retiring + topdown\\-be\\-bound)",
"MetricGroup": "TopdownL1;tma_L1_group",
"MetricName": "tma_retiring",
...
it looks like the group will fail due to the missing slots event. This
can be fixed with:
"MetricExpr": "topdown\\-retiring / (topdown\\-fe\\-bound +
topdown\\-bad\\-spec + topdown\\-retiring + topdown\\-be\\-bound) + 0
* TOPDOWN.SLOTS",
Thanks,
Ian

I just test all the events for SPR/ADL, no error find.
But there are a lots of metrics fail due to slots missed.

Events remain at v26, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v19, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Uncore event updates by Zhengjun Xing <zhengjun.xing@linux.intel.com>.
- 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v1.16, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Removal of ScaleUnit from uncore events by Zhengjun Xing
<zhengjun.xing@linux.intel.com>.
- 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events are updated to v32, the core metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events are updated to v26, the core metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Uncore event updates by Zhengjun Xing <zhengjun.xing@linux.intel.com>.
- 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. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events are updated to v1.15, the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events are updated to v1.16 the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v22, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Maximizing Retiring typically increases the Instructions-per-cycle (see IPC metric). Note that a high Retiring value does not necessary mean there is no room for more performance. For example; Heavy-operations or Microcode Assists are categorized under Retiring. They often indicate suboptimal performance and can often be optimized or avoided. SMT version; use when SMT is enabled and measuring per logical CPU."

A CISC instruction has multiple uops that are required to perform the instruction's functionality as in the case of read-modify-write as an example. Since these instructions require multiple uops they may or may not imply sub-optimal use of machine resources."

Events are updated to v22 the core metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v21, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v17, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events are updated to v1.06 the core metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v53, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v1.07, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

Events remain at v23, and the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Switch for core metrics from BDX to BDW.
- Switch for Page_Walks_Utilization to BDX version.
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- 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.
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

If so, all the scripts with the old name must be broken on the existing
platforms. Can we keep both old name and new name for the existing
platforms?
For the event naming, if we want to rename an event. We still keep the
old name and mark it as deprecated in the existing platforms to maintain
compatibility.
Can we do the similar thing for metrics?
For the existing platforms, just add all the metrics from the
perfmon-metrics and don't change the existing metrics unless they have
errors.
Thanks,

Thanks Kan,
Do we have examples of scripts that will be impacted by this? My
thoughts are that such scripts are likely using TopdownL1 as a metric
group, the metrics within that group vary and names may change over
time. For example, on hybrid there is Backend_Bound_Aux. Given the
existing state, such compatibility is only required for level 1
metrics on CNL CPX CLX KBLR/CFL/CML SKX SKL/KBL BDX BDW HSX HSW IVT
IVB JKT/SNB-EP SNB. Injecting either a metric group or an aliasing
metric is messy and when can we stop carrying the patch? There hasn't
been discussion of doing this in the context of:
https://github.com/intel/perfmon-metrics
I'd suggest that this is a good time for script writers to change how
they use particular metrics and derive the information instead from
groups like TopdownL1. This will also make them robust to changes in
the TMA metrics CSV files, another win.
Thanks,
Ian

So the rename only impacts the Topdown metrics, right?
We still keep the old group name, TopdownL1.
If so, I agree. It only makes sense when collect in a Top-down group,
not specific metrics.
