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.
