Nit picking here, but "All instruction fetches" doesn't occur in
PMCx094's description. I'm looking at both Model 71h and 31h
documentation. This event specifically calls out the context of
the L1 ITLB and its *hits*, i.e., specifically this text:

> + "PublicDescription": "The number of instruction fetches that hit in the L1 ITLB.",

So this is the text that should probably be in the BriefDescription
as well, but if both BriefDescription and PublicDescription are going
to be equal, just provide the BriefDescription version, since it
shows with and without the -v and --details flags to perf list.

"The number of instruction fetches that hit in the L1 ITLB. Instruction fetches to a 1 GB page."

Concatenate the BriefDescription text here.

Concatenate the BriefDescription text here.

Where is the "Data Cache Reads (including hardware and software prefetch)."
text from the document(s)?

Here too: missing unit mask description text.

same with all the above.

This text doesn't match the text in either of these:

PPR for AMD Family 17h Model 71h B0 - 56176 Rev 3.06 - Jul 17, 2019
PPR for AMD Family 17h Model 31h B0 - 55803 Rev 0.54 - Sep 12, 2019

The text in the above is an improved version from the Zen 1 variants.
Care to use the text from these documents?

These events produce zero counts on Zen 2;
they need a "UMask": "0xff".

The above are not up to date, e.g., unit mask 0x2 is now
TlbReloadCoalescedPageHit.

Also, wherever BriefDescription equals PublicDescription,
please only provide the BriefDescription.

All the above Public descriptions have "RETIRE Tokens unavailable."
yet their BriefDescriptions are different. Please fix.

All the above events have updated text in the documents; please
update the text here too.

Patch 1 of 3 looks OK to me. Assuming there are no further
comments to this version, please make the requested changes
to patches 2 and 3 of the series, and resend as a v3.

Thanks!
