Add the event description for the IBM z16 pai_ext PMU released with
commit c432fefe8e62 ("s390/pai: Add support for PAI Extension 1 NNPA counters")
The document SA22-7832-13 "z/Architecture Principles of Operation",
published May, 2022, contains the description of the
Processor Activity Instrumentation Facility and the NNPA counter
set., See Pages 5-113 to 5-116.

Since the Brief description mentions NNPA, shouldn't the Public
Description expand on this "NNPA" acronym?, something like:
Oops, can't expand on that since there isn't a link to that SA22-7832-13
document.
Googling for it...

Ok, requires registration.
I wonder what is the value of these descriptions then :-\
I miss Ingo jumping into these discussions :-)

I added Andreas Krebbel to the discussion, he knows more than I on this counters.
NNPA stands for Neural Networks Processing Assist. This is a new feature in
the IBM z16. Here is a quote from Document SG2489-51 IBM z16 (3931) Technical Guide:
<START-OF-QUOTE>
"The new IBM z16 microprocessor chip, also called the IBM Telum processor, integrates a
new AI accelerator. This innovation brings incredible value to applications and workloads that
are running on IBM Z platform.
Customers can benefit from the integrated AI accelerator by adding AI operations that are
used to perform fraud prevention and fraud detection, customer behavior predictions, and
supply chain operations. All of these operations are done in real time and fully integrated in
transactional workloads. As a result, valuable insights are gained from their data instantly.
...
The AI accelerator is driven by the new Neural Networks Processing Assist (NNPA)
instruction.
NNPA is a new nonprivileged Complex Instruction Set Computer (CISC) memory-to-memory
instruction that operates on tensor objects that are in user program’s memory. AI functions
and macros are abstracted by NNPA."
<END-OF-QUOTE>
This intension of this patch is to give a small hint on what these NNPA counters are
supposed to count and operate on. A full explanation is given in the document
SA22-7832-13 "z/Architecture Principles of Operation", Chapter 26, pp 26-1 to 26-115.
If you think this small description is not worth it, then we can drop the patch.
Thanks for you help and directions.

So perhaps:
+ {
+ "Unit": "PAI-EXT",
+ "EventCode": "6144",
+ "EventName": "NNPA_ALL",
+ "BriefDescription": "NNPA ALL",
+ "PublicDescription": "Sum of all non zero NNPA (Neural Networks Processing Assist) counters"
+ },
?

Ahhh, now I get it.
Yes I will provide a patch with the first mention of NNPA have
the abbreviation explained, as you pointed out.
Thanks.
