If this is indeed specific to 12th gen CPUs, then my guess is that hybrid CPUs are to blame. E.g. KVM already disables vPMU (commit 4d7404e5ee00 "KVM: x86/pmu: Disable vPMU support on hybrid CPUs (host PMUs)"), I wouldn't be at all surprised if there are more problems lurking. -- You may reply to this email to add a comment.
