RE: [PATCH v2 3/3] perf vendor events: Add Fujitsu A64FX V1.2 pmu event

Hi John

I think that we need to the same here as the IMPDEF recommended events - add a
common JSON to reduce the duplication.

I had done work on this for current CPUs, but never got it finished. Let me check
the status.

If you let me know the result, I will resend the patch according to the policy.

Best Regards

Ps, arm have put JSONs here for their cores:

https://github.com/ARM-software/data/tree/master/pmu

But unfortunately the schema does not suit perf.

I raised an issue, but no response.

I'm just wondering if you hand copied the JSON data.
