NVDIMM support
Comment 1 Conrad Meyer freebsd_committer freebsd_triage 2018-06-12 17:53:00 UTC 
NVDIMM-N, -F, -P?  Does the project own any -N or -P hardware in any of the labs?  I think kib committed (or posted a patch for) some partial support already.

What's left as far as basic support?  This general subject could encompass a ton of work; presumably we are not going to try and make e.g. filesystems NVDIMM-aware for 12.0.  Do we want to provide a separate vmem for each NVDIMM in 12?  Or some other abstraction?
Comment 2 Scott Lamons 2018-06-12 21:30:18 UTC 
Regarding hardware we now have an HP Proliant Gen10 system with 2x16GB NVDIMM-N and 16GB of RDIMM for boot installed at OSU Open Source Lab (OSL).  I can provide access info for FreeBSD developers who would like to help test Kostik's patch and potentially contribute to the outgoing development.

The NVDIMM-related work intended to land in 12.0 is complete.
