Request to back port vmci patches to Ubuntu kernel

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 1978145

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.

Since this is a request to port patches from upstream to Ubuntu kernels,
setting the status to 'Confirmed'.

Please try the test kernel at https://kernel.ubuntu.com/~rtg/jammy-vmci-updates-lp1978145/5.15.0-37.38~lp1978145.1/

wget https://kernel.ubuntu.com/~rtg/jammy-vmci-updates-lp1978145/5.15.0-37.38~lp1978145.1/amd64/linux-image-unsigned-5.15.0-37-generic_5.15.0-37.38~lp1978145.1_amd64.deb

sudo dpkg -i *.deb
sudo reboot

Thanks a lot for the quick response, Tim!

We have completed our testing on x86 and it looks good from our
point of view. We are in the process of testing on arm64.
Will keep you posted on the progress.

Thanks,
Vishnu

Patches submitted: https://lists.ubuntu.com/archives/kernel-team/2022-June/130976.html

Hi Vishnu - can you expand a bit as to the purpose of these patches ? Are they solely for the purpose of adding arm64 support ?

rtg

Hi Tim,
No, not exactly. We have a new version of the VMCI device itself and
patches #1 to #11 provide support for that, see [1] for some information
on what is new. #12 adds arm64 support (we only support the new version
of the VMCI device in arm64, but both old and new versions of VMCI
device are supported in x86). #13 is a general bugfix. All 13 patches
can build on both x86 and arm64. Please let me know if this helps.

Tim,
We're seeing some unrelated issues with the arm64 test kernel you shared.
Is it possible for you to provide arm64 test kernel that is based on
5.15.0-39 instead of 5.15.0-37?

Thanks,
Vishnu

Hi Vishnu,

Try the kernel at https://kernel.ubuntu.com/~rtg/jammy-vmci-updates-lp1978145/5.15.0-41.44~lp1972662.1/. This is the kernel that will be tested for this SRU cycle. I've also updated the git repo at 'git://git.launchpad.net/~timg-tpi/ubuntu/+source/linux/+git/jammy jammy-vmci-updates-lp1978145'.

rtg

Thanks a lot, Tim! This worked and our testing went fine.

So, to sum up -- our testing on both x86 and arm64 passed and
looks good from our point of view

Thanks,
Vishnu

This bug is awaiting verification that the linux/5.15.0-41.44 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!

I have changed the tag to verification-done-jammy as the fix has been
