Add support for mdev_set_iommu_device() kABI in Ubuntu 22.10 kernel

it's incorrect to file bugs againt `linux-meta` bugs like these should be filed against `linux` itself.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1988806

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Is https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/kinetic/commit/?h=master-next&id=e605d68b8accf43430144999e8206dd8511d135f still needed in v6.2 kernel. It no longer applies, and there has been a lot of work by @nvidia.com people on the driver in question (nicolinc kwankhede jgg)

Hi Dimitri,

Yes, this patch is still needed with Ubuntu 23.04 for making sure vGPU works with it.

You're right that the patch will not apply cleanly due to upstream changes in the code, should I post a new patch for this? Can you also let me know the latest by which this patch can go in Ubuntu 23.04 (Lunar)?

Yes, it is expected for you / Nvidia to update this patch if there is no other solution.

Please provide patch for v6.2 for lunar & vanilla kernel latest RC.

Ideally also submit it upstream, such that a solution acceptable upstream is eventually found.

This patch will need to go through acks, and integrated into an SRU cycles once available. Initial lunar kernel for GA has frozen weeks ago. So this will land in SRU cycle when next possible (April/may). Thus for a while 23.04 will have this regression.

I will separately check which rebase dropped this patch and how come notification about it did not get communicate prior to being identified and escalated to me just today. I do apologise about it.

This bug is awaiting verification that the linux/6.2.0-25.25 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-lunar' to 'verification-done-lunar'. If the problem still exists, change the tag 'verification-needed-lunar' to 'verification-failed-lunar'.

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!

Hi Tarun,

In preparation to Mantic release, Can you confirm if fixes are no longer required? Does the driver contain fixes that no longer require the fix?

Thanks!

If this patch is still needed will you submit forward port by end of today? Given today is Kernel Feature Freeze with hardward support freeze on Monday.

Hi Dimitri and Jose,

I've posted the patch for review as requested for 23.10 kernel. Refer https://lists.ubuntu.com/archives/kernel-team/2023-September/142909.html .

Please help review

Thanks,
Tarun

Hello Tarun,

More details about this patch will continue privately via email.

For the record here, this patch missed the deadline.

Regards,

Jose
