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