[PATCHv4 07/13] node: Add heterogenous memory access attributes

2019-01-16 Thread Keith Busch
Heterogeneous memory systems provide memory nodes with different latency and bandwidth performance attributes. Provide a new kernel interface for subsystems to register the attributes under the memory target node's initiator access class. If the system provides this information, applications may
