I can verify from IBM's standpoint, that we were able to use Volta gpu's
with POWER9.  The Nvidia driver enabled correctly.

[Kernel-packages] [Bug 1772991] Re: [Ubuntu 18.04.1] POWER9 - Nvidia Volta - Kernel changes to enable Nvidia driver on bare metal

2018-06-14 Thread Brad Figg 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

We are still waiting for a couple of acks at this point.  The patch set
should meeting the SRU criteria, just waiting for review.  I'll resend
the SRU request if the acks don't happen soon.

hi Joseph,

I tried to discover if the patchset above was accepted/acked but I
didn't find anything. Do you know if the patchset would make the SRU
criteria?

[Kernel-packages] [Bug 1772991] Re: [Ubuntu 18.04.1] POWER9 - Nvidia Volta - Kernel changes to enable Nvidia driver on bare metal

2018-05-23 Thread Joseph Salisbury 
I built a Bionic test kernel with the 9 commits posted in the bug description.  
The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1772991

Can you test this kernel and see if it resolves this bug?

Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the 
linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the 
linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

Thanks in advance!
