Andi, I just noticed that metric groups appear when we pass some substring to search events that looks unrelated, can you please take a look at this?

[root@jouet ~]# perf list energy-cores oList of pre-defined events (to be used in -e):
power/energy-cores/ [Kernel PMU event]
Metric Groups:
DSB: DSB_Coverage [Fraction of Uops delivered by the DSB (aka Decoded Icache; or Uop Cache)] FLOPS: GFLOPs [Giga Floating Point Operations Per Second] Frontend: IFetch_Line_Utilization [Rough Estimation of fraction of fetched lines bytes that were likely consumed by program instructions] Frontend_Bandwidth: DSB_Coverage [Fraction of Uops delivered by the DSB (aka Decoded Icache; or Uop Cache)] Memory_BW: MLP [Memory-Level-Parallelism (average number of L1 miss demand load when there is at least 1 such miss)] Memory_Bound: Load_Miss_Real_Latency [Actual Average Latency for L1 data-cache miss demand loads] MLP [Memory-Level-Parallelism (average number of L1 miss demand load when there is at least 1 such miss)] Memory_Lat: Load_Miss_Real_Latency [Actual Average Latency for L1 data-cache miss demand loads] Pipeline: CPI
