There's a relative small patchset that I'm going to send to Canonical Kernel Team using this buglink. On the host side we'll be running a custom version of Ubuntu 18.04 (kernel + qemu). However on the guest side it will be *very important* for clients to simply download the Ubuntu 18.04 from Canonical's website and have the NVLink2 working out of the box. For that, we have worked on a small patchset using only upstream patches without changing beyond our area. As soon as I send the patchset to the mailing list I'll update this bug with a link to that message. Thank you very much, Jose R.
