2 tristate "DAX: direct access to differentiated memory"
4 default m if NVDIMM_DAX
9 tristate "Device DAX: direct access mapping device"
10 depends on TRANSPARENT_HUGEPAGE
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.
21 tristate "PMEM DAX: direct access to persistent memory"
22 depends on LIBNVDIMM && NVDIMM_DAX && DEV_DAX
25 Support raw access to persistent memory. Note that this
26 driver consumes memory ranges allocated and exported by the
