21 The Nest PMU counters are handled by a Nest IMC microcode which runs in the OCC
23 the nest IMC counter data to memory.
25 The Core and Thread IMC PMU counters are handled in the core. Core level PMU
26 counters give us the IMC counters' data per core and thread level PMU counters
27 give us the IMC counters' data per CPU thread.
