Support raw access to differentiated (persistence, bandwidth,
|

|
latency...) memory via an mmap(2) capable character
|
||
|
device. Platform firmware or a device driver may identify a
|
||
|
platform memory resource that is differentiated from the
|
||
|
baseline memory pool. Mappings of a /dev/daxX.Y device impose
|
||
|
restrictions that make the mapping behavior deterministic.
