The Perfmon and Debug Capability MSR named IA32_PERF_CAPABILITIES is a feature-enumerating MSR, which only enumerates the feature full-width write (via bit 13) by now which indicates the processor supports IA32_A_PMCx interface for updating bits 32 and above of IA32_PMCx. The existence of MSR IA32_PERF_CAPABILITIES is enumerated by CPUID.1:ECX[15].
