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"
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"
