| 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. |
