6 tristate "DAX: direct access to differentiated memory"
8 default m if NVDIMM_DAX
13 tristate "Device DAX: direct access mapping device"
14 depends on TRANSPARENT_HUGEPAGE
16 Support raw access to differentiated (persistence, bandwidth,
17 latency...) memory via an mmap(2) capable character
18 device. Platform firmware or a device driver may identify a
19 platform memory resource that is differentiated from the
20 baseline memory pool. Mappings of a /dev/daxX.Y device impose
21 restrictions that make the mapping behavior deterministic.
24 tristate "PMEM DAX: direct access to persistent memory"
25 depends on LIBNVDIMM && NVDIMM_DAX && DEV_DAX
28 Support raw access to persistent memory. Note that this
29 driver consumes memory ranges allocated and exported by the
