27 of four fixed and architecturally defined 64-bit event counters.
37 When in WFI or WFE these counters do not increment.
40 event counters. Future versions of the architecture may use this space to
41 implement additional architected event counters.
44 64-bit event counters.
46 On cold reset all counters reset to 0.
59 counters, only the presence of the extension.
66 - Enable the counters. If not enabled these will read as 0.
67 - Save/restore the counters before/after the CPU is being put/brought up

14 counters. Counters are independently programmable to different events and
15 can be started and stopped individually. None of the counters support an
16 overflow interrupt. DMC and L3C counters are 32-bit and read every 2 seconds.
