Title:
Add basic support to NVLink2 passthrough
Status in The Ubuntu-power-systems project:
Fix Committed
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Bionic:
Fix Committed
Bug description:
This bug exists to track the basic support to NVLink2 passthrough on
Ubuntu 18.04 - for the guest side only. 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. Ziviani
