Thanks Arnaldo, it looks like this problem exists on all the hybrid
metrics which are sourced from the following (look for cpu@ that
should be cpu_core@):
https://github.com/intel/perfmon/blob/main/ADL/metrics/perf/alderlake_metrics_goldencove_core_perf.json
https://github.com/intel/perfmon/blob/main/ARL/metrics/perf/arrowlake_metrics_lioncove_core_perf.json
https://github.com/intel/perfmon/blob/main/LNL/metrics/perf/lunarlake_metrics_lioncove_core_perf.json
https://github.com/intel/perfmon/blob/main/MTL/metrics/perf/meteorlake_metrics_redwoodcove_core_perf.json
I'll need Caleb to do a new version of these metrics before I can send
out the updated version.

Thanks,
Ian
