Does 384.90 support HMM in the 4.14 kernel?

In particular, I’m asking about CUDA support – If I use 384.90 with kernel 4.14, can I pass a host-malloced pointer to a CUDA kernel?

Not yet. There’s some work in progress for that.

and 387.12? it’s from a new branch? if not should be there for 390.xx branch early next year?
if yes 390.xx should be a pretty big reléase with support for Xorg 1.20 with HDR DeepColor ext. and GLVND server support…
