+ help
+ Generic support for non-volatile memory devices including
+ ACPI-6-NFIT defined resources. On platforms that define an
+ NFIT, or otherwise can discover NVDIMM resources, a libnvdimm
+ bus is registered to advertise PMEM (persistent memory)
+ namespaces (/dev/pmemX) and BLK (sliding mmio window(s))
+ namespaces (/dev/ndX). A PMEM namespace refers to a memory
+ resource that may span multiple DIMMs and support DAX (see
+ CONFIG_DAX). A BLK namespace refers to an NVDIMM control
+ region which exposes an mmio register set for windowed
+ access mode to non-volatile memory.
