The SDM explicitly states that PEBS Baseline implies Extended PEBS. For cpu model forward compatibility (e.g. on ICX, SPR, ADL), it's safe to stop doing FMS table thing such as setting pebs_capable and PMU_FL_PEBS_ALL since it's already set in the intel_ds_init(). The Goldmont Plus is the only platform which supports extended PEBS but doesn't have Baseline. Keep the status quo.
