| 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. | |
