Change Details

The tree is available at: https://gitlab.com/scott-ph/FreeBSD/tree/wip/nvdimm-ns Mostly, I'd like feedback on the usage of GETATTR to convey label information from the SPA. I'll also need an interface to write to the NVDIMM label areas, which I'm thinking of adding as a ctlreq method of the SPA. Feedback on that would also be appreciated. The data model of the NFIT and label structures is fairly convoluted, so I'm happy to provide a summary if someone wants to provide feedback but isn't familiar.

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.
