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. Sample with: UOPS_RETIRED.SLOTS",

Thanks Arnaldo, it looks like this problem exists on all the hybrid
metrics which are sourced from the following (look for cpu@ that
should be cpu_core@):
https://github.com/intel/perfmon/blob/main/ADL/metrics/perf/alderlake_metrics_goldencove_core_perf.json
https://github.com/intel/perfmon/blob/main/ARL/metrics/perf/arrowlake_metrics_lioncove_core_perf.json
https://github.com/intel/perfmon/blob/main/LNL/metrics/perf/lunarlake_metrics_lioncove_core_perf.json
https://github.com/intel/perfmon/blob/main/MTL/metrics/perf/meteorlake_metrics_redwoodcove_core_perf.json
I'll need Caleb to do a new version of these metrics before I can send
out the updated version.
Thanks,
Ian

Ideally the Frontend can issue Pipeline_Width uops every cycle to the Backend. Frontend Bound denotes unutilized issue-slots when there is no Backend stall; i.e. bubbles where Frontend delivered no uops while Backend could have accepted them.

The core enters the halt state when it is running the HLT instruction or the MWAIT instruction. This event is not affected by core frequency changes (for example, P states, TM2 transitions) but has the same incrementing frequency as the time stamp counter. This event can approximate elapsed time while the core was not in a halt state. This event has a constant ratio with the CPU_CLK_UNHALTED.REF_XCLK event. It is counted on a dedicated fixed counter, leaving the four (eight when Hyperthreading is disabled) programmable counters available for other events. \nNote: On all current platforms this event stops counting during 'throttling (TM)' states duty off periods the processor is 'halted'. This event is clocked by base clock (100 Mhz) on Sandy Bridge. The counter update is done at a lower clock rate then the core clock the overflow status bit for this counter may appear 'sticky'. After the counter has overflowed and software clears the overflow status bit and resets the counter to less than MAX. The reset value to the counter is not clocked immediately so the overflow status bit will flip 'high (1)' and generate another PMI (if enabled) after which the reset value gets clocked into the counter. Therefore, software will get the interrupt, read the overflow status bit '1 for bit 34 while the counter value is less than MAX. Software should ignore this case.",

One can calculate the bandwidth of the link by taking: flits*80b/time. Note that this is not the same as data bandwidth. For example, when we are transferring a 64B cacheline across QPI, we will break it into 9 flits -- 1 with header information and 8 with 64 bits of actual data and an additional 16 bits of other information.

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",

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: ASSISTS.ANY",

For example, when we are transferring a 64B cacheline across QPI, we will break it into 9 flits -- 1 with header information and 8 with 64 bits of actual data and an additional 16 bits of other information.

Update events from v1.10 to v1.11.
Update TMA metrics from 4.8 to 5.01.
Bring in the event updates v1.11:
https://github.com/intel/perfmon/commit/b9dabd05ff44af24fde0682e16d1a716c932f0d0
This updates the mapfile.csv for the 0xB5 CPUID variant of meteorlake.
https://github.com/intel/perfmon/commit/c3094bc9bbaff30071874a492afc3369554d572e
The TMA 5.01 addition is from (with subsequent fixes):

While this often indicates efficient X86 instructions were executed; high value does not necessarily mean better performance cannot be achieved.

Update events from v1.23 to v1.25.
Update TMA metrics from 4.8 to 5.01.
Bring in the event updates v1.25:
https://github.com/intel/perfmon/commit/78d6273c546329052429e3a005491b58fbe1167b
https://github.com/intel/perfmon/commit/f069ed9d0b69b02d76d4b4c59dfc75b62bfb2254
The TMA 5.01 addition is from (with subsequent fixes):
https://github.com/intel/perfmon/commit/1d72913b2d938781fb28f3cc3507aaec5c22d782
Update uncore IIO events umask with the change:
https://github.com/intel/perfmon/commit/d78e8a166537c9ceab4f2e901dc96c53667a2174
which should address an issue originally raised by Michael Petlan:

Instead; a sequence of instructions to perform the computation on the Denormals is injected into the pipeline.

Happy new year and thanks Kan! Arnaldo, Namhyung please let me know if
there is anything more necessary for this series. I don't believe it
needs a rebase.

So, the Co-authored-by: tag was used and it is not documented in
Documentation/process/submitting-patches.rst, I think the right tag her
is "Co-developed-by:", and there are some rules about its usage, from
that doc:

Co-developed-by: states that the patch was co-created by multiple developers;
it is used to give attribution to co-authors (in addition to the author
attributed by the From: tag) when several people work on a single patch. Since
Co-developed-by: denotes authorship, every Co-developed-by: must be immediately
followed by a Signed-off-by: of the associated co-author. Standard sign-off
procedure applies, i.e. the ordering of Signed-off-by: tags should reflect the
chronological history of the patch insofar as possible, regardless of whether
the author is attributed via From: or Co-developed-by:. Notably, the last
Signed-off-by: must always be that of the developer submitting the patch.

Thanks Arnaldo, this makes sense to me. Caleb is adding Signed-off-by
tags from you okay?
