The only way to add more System RAM is via add_memory() and friends like

Yeah, my point was more towards whether PMEM can come in a way that it does
not have to be hotplugged, but come functional by default (as RAM).
But after having read all papers out there, I do not think that it is possible.
You mean e.g., configuring in the BIOS/firmware how an NVDIMM will get
exposed to the OS (pmem vs. RAM). I once heard something about that, not
sure if it's real. But from Linux' perspective, it would simply be
System RAM and it would get treated like that.
