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