  12          Support raw access to differentiated (persistence, bandwidth,
  13          latency...) memory via an mmap(2) capable character
  14          device.  Platform firmware or a device driver may identify a
  15          platform memory resource that is differentiated from the
  16          baseline memory pool.  Mappings of a /dev/daxX.Y device impose
  17          restrictions that make the mapping behavior deterministic.
