According to Intel SDM, the EPT-friendly PEBS is supported by all the platforms after ICX, ADL and the future platforms with PEBS format 5. Currently the only in-kernel user of this capability is KVM, which has very limited support for hybrid core pmu, so ADL and its successors do not currently expose this capability. When both hybrid core and PEBS format 5 are present, KVM will decide on its own merits.
