However, this week I read a post on Reddit[2] that was a bit disturbing to me. Meaningfully, it proclaims that the main development platform for nvmm is now DragonflyBSD rather than NetBSD. It also claims that the implementation in NetBSD is now "stale and broken". Comparing the timestamps of the last commits in the repositories [3] and [4], the last activities are only three months apart. The nature and extent of the respective changes is difficult for me to evaluate. Is anyone here deeper into this and can say what the general state of nvmm in NetBSD is? 1) nvmm seems to work well in netbsd (I haven't run it yet) and there has been bug fixing. 2) code flows between BSDs a lot, in many directions. 3) You could run diff to see what's different and why. 4) The language in the reddit post does not sound particularly constructive. Someone with knowledge of improved code in DragonFly (I don't know if that's true or not) could send a message here or teech-kern pointing it out and suggesting we update, rather than being dismissive on reddit. Or file PRs and list them; technical criticism is fair. Probably after your message (which I view as helpful) someone(tm) will look at the diff. But if you are inclined to do that and post some comments, that's probably useful.
