[PATCH v1] perf jevents: Add mesh bandwidth saturation for CWF, EMR, GRR, SNR, SPR, SRF

[PATCH v1] perf jevents: Add mesh bandwidth saturation for CWF, EMR, GRR, SNR, SPR, SRF

[Ian Rogers]

Extend the mesh bandwidth saturation's list of events to include
events from clearwaterforest, emeraldrapids, grandridge,
graniterapids, sapphirerapids and sierraforest. This makes the
lpm_mem_sat metric available for those CPU models.

Thanks, applied to perf-tools-next, for v7.4.
