Title:
[Ubuntu 16.04] NVLINK support for Garrison
Status in linux package in Ubuntu:
Fix Committed
Status in linux source package in Xenial:
Fix Committed
Bug description:
This is a feature request to support NVLink for POWER8 processor and
NVIDIA.
We're still in early hardware bring up at this stage, but thankfully
the kernel patches are reasonably small. At this stage I'm hoping to
get the first version of the patches posted to the mailing lists in
the next couple of days meaning that they will hopefully get into 4.5.
Bug mirrored for Canonical awareness. A backport from 4.5 will be
required once the patch is accepted.
