[ Test case ]

Install the latest linux-6.17 kernel on Noble:

$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge

Install intel-vsc-dkms:

$ sudo apt install intel-vsc-dkms

Module built and installed successfully

Load the modules:

$ sudo modprobe ljca
$ sudo modprobe spi-ljca
$ sudo modprobe gpio-ljca
$ sudo modprobe i2c-ljca
$ sudo modprobe mei-vsc
$ sudo modprobe intel_vsc
$ sudo modprobe mei_csi
$ sudo modprobe mei_ace
$ sudo modprobe mei_pse
$ sudo modprobe mei_ace_debug

Modules loaded successfully

The same procedure should must be repeated on linux-6.8 and linux-6.14 to test for possible regressions.

[ Fix ]

Patches to enable kernels >= 6.8:

-debian/patches/0006-Linux-6.8-through-6.17-compat.patch
-Adding dh-dkms as dependency

Adding Ubuntu Developers as Maintainer

[ Regression potential ]

We may experience regressions in systems that are using the intel-vsc drivers, especially with kernels >= 6.8 kernel.

Hello John, or anyone else affected,

Accepted ivsc-driver into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ivsc-driver/0~git202311021215.73a044d9-0ubuntu2.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Modules built and installed successfully. All modules loaded successfully on 6.17 kernel, but some did not on a 6.8 kernel. However, the current released module also fails to load the same modules, so this does not constitute a regression.

6.17 kernel:

root@noble-hwe-vm:~# uname -r
6.17.0-7-generic
root@noble-hwe-vm:~# modprobe ljca; modprobe spi-ljca; modprobe gpio-ljca; modprobe i2c-ljca; modprobe mei-vsc; modprobe intel_vsc; modprobe mei_csi; modprobe mei_ace; modprobe mei_pse; modprobe mei_ace_debug

6.8 kernel:

root@noble-lts-vm:~# modprobe ljca; modprobe spi-ljca; modprobe gpio-ljca; modprobe i2c-ljca; modprobe mei-vsc; modprobe intel_vsc; modprobe mei_csi; modprobe mei_ace; modprobe mei_pse; modprobe mei_ace_debug
modprobe: ERROR: could not insert 'mei_vsc': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: could not insert 'mei_csi': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: could not insert 'mei_ace': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: could not insert 'mei_pse': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: could not insert 'mei_ace_debug': Unknown symbol in module, or unknown parameter (see dmesg)

[Andreas Hasenack (ahasenack)]

I can confirm the existing failure on 6.8. I also tested the current HWE kernel, 6.14, and the build and loading of modules worked with 0~git202311021215.73a044d9-0ubuntu2.1. Also, the non-updated dkms package fails to build with 6.14 HWE as well, and the updated one works.

[Andreas Hasenack (ahasenack)]

I was about to release this yesterday, but then the LP outage happened, and we don't do releases on Fridays (today). Next opportunity window starts next Monday.

[John Cabaj (john-cabaj)]

Thanks for the updates Andreas!
