2 tristate "DAX: direct access to differentiated memory"
3 default m if NVDIMM_DAX
4 depends on TRANSPARENT_HUGEPAGE
7 Support raw access to differentiated (persistence, bandwidth,
8 latency...) memory via an mmap(2) capable character
9 device. Platform firmware or a device driver may identify a
10 platform memory resource that is differentiated from the
11 baseline memory pool. Mappings of a /dev/daxX.Y device impose
12 restrictions that make the mapping behavior deterministic.
17 tristate "PMEM DAX: direct access to persistent memory"
18 depends on LIBNVDIMM && NVDIMM_DAX
21 Support raw access to persistent memory. Note that this
22 driver consumes memory ranges allocated and exported by the
28 int "Maximum number of Device-DAX instances"
