SubjectRe: [PATCH v4 3/3] perf vendor events amd: update Zen1 events to V2
Hi Kim,

As you can see, my diff for Patch 3 has inflated since the last version.
This is mostly because I have updated the descriptions of the counters
that were already in zen1 based on your review for the patch for zen2.

Best,
Vijay

> Changes in v4:
> - PMC 0x46 add missing subcounters for types 0 and 1 of tablewalker
> allocation
> - PMC 0x60 and 0x61: add missing detail on brief descriptions
> - change descriptions of many of the events to bring them in-line
> with improvements made in patch 2/3. These were for counters that
> did not change between zen1 to zen2. Patch reviews for zen2 lead
> these descriptions to be changed and improved, and many of these
> have been carried here in this version of patch 3.
