From 3d88002e4a7bd40f355550284c6cd140e6fe29dc Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Sun, 31 May 2015 15:02:11 -0400 Subject: libnvdimm: support for legacy (non-aliasing) nvdimms The libnvdimm region driver is an intermediary driver that translates non-volatile "region"s into "namespace" sub-devices that are surfaced by persistent memory block-device drivers (PMEM and BLK). ACPI 6 introduces the concept that a given nvdimm may simultaneously offer multiple access modes to its media through direct PMEM load/store access, or windowed BLK mode. Existing nvdimms mostly implement a PMEM interface, some offer a BLK-like mode, but never both as ACPI 6 defines. If an nvdimm is single interfaced, then there is no need for dimm metadata labels. For these devices we can take the region boundaries directly to create a child namespace device (nd_namespace_io).
