    24	Version 1 of the Activity Monitors architecture implements a counter group
    25	of four fixed and architecturally defined 64-bit event counters.
  > 26	  - CPU cycle counter: increments at the frequency of the CPU.
    27	  - Constant counter: increments at the fixed frequency of the system
    28	    clock.
    29	  - Instructions retired: increments with every architecturally executed
    30	    instruction.
    31	  - Memory stall cycles: counts instruction dispatch stall cycles caused by
    32	    misses in the last level cache within the clock domain.
