Conrad Meyer	43e4b6ca7f	nvdimm(4): Persist unit numbers in cdev ... They're formatted into the device name like unit numbers, anyway; store the number in mda_unit => si_drv0 like dev2unit() expects. No functional change intended. Sponsored by: Dell EMC Isilon	2019-10-18 21:32:45 +00:00
Conrad Meyer	515013704d	nvdimm(4): Calculate and save memattr once; it never changes ... Refactor nvdimm_spa_memattr() routine and callers to just save the value at initialization and use the value directly. The reference value from NFIT, MemoryMapping, is read only once, so the associated memattr could never change. No functional change. Sponsored by: Dell EMC Isilon	2019-10-10 22:49:45 +00:00
Ben Widawsky	8ebb6dddb5	nvdimm: Simple namespace support ... Add support for simple NVDIMM v1.2 namespaces from the UEFI version 2.7 specification. The combination of NVDIMM regions and labels can lead to a wide variety of namespace layouts. Here we support a simple subset of namespaces where each NVDIMM SPA range is composed of a single region per member dimm.
