Not working on Ubuntu 24.04 with kernel 6.8

[rmasad]

Previously, I managed to get the camera working with this guide on Ubuntu 23.04: https://dshedd.com/2023/07/18/fixing-lenovos-mipi-camera-problems-on-ubuntu-22-04/

Today, I updated to Ubuntu 24.04 (kernel 6.8.0-31-generic) and my camera stopped working. I repeated the steps and still have problems.

I have a dell precision 5680 and it is now working in 24.04 too...

[rmasad]

What kernel version do you have?
Any extra step do you do that fix the camara?

[AntiNSA]

I've tried 6.8 and 6.9 and 6.91 and it doesn't work no matter what I do.

What's more strange is that I go back to kernel 6.5.0-35-generic (where it worked before) and it doesn't work anymore.

[yorik]

I was silly enough to upgrade kernel to 6.8 and the driver the latest and my camera doesn't work anymore:

int3472-discrete INT3472:06: cannot find GPIO chip INTC1096:00, deferring

Before I had kernel 6.6 for 3 months and it worked fine. Unfortunately rolling back to kernel 6.6 and even all 4 ipu6 repos to ~February did help.
The laptop: X1 Carbon Gen 11.
Debian sid with patched kernel.

Ubuntu 24.04 with kernel and packages from the 6.8.0-32 series (currently in noble-proposed) do work out of the box. To get the noble-proposed packages, one need to select Software & Updates->Developer Options->pre-release updates, apt update, and apt install the 6.8.0-32 linux image, module, and dkms packages. These image and module packages contain the upstream kernel patches and intel-ipu6 drivers.

For example, it just works with zoom.

It is not perfect, however. Sometimes the video hangs and needs to be reset. Sometimes these hangs prevent the system from suspending which requires a reboot. But it's usable. Hoping that this will soon be reliable?

I should say: I have a Carbon X11 Gen 11. For some reason, this hardware is particularly finicky by combining experiences of others.

Hmmm. No updates available after toggling pre-release updates then apt update.

I think you need to apt install the packages directly. Not an apt upgrade. So stuff like:

apt install linux-generic-hwe-24.04/noble-proposed linux-headers-generic-hwe-24.04/noble-proposed
apt install linux-modules-ipu6-6.8.0-32-generic/noble-proposed

Hopefully, I didn't miss one (this is by memory). I also seemed to need:

apt reinstall intel-ipu6-dkms

Not 100% sure that this is right. But it worked.

[AntiNSA]

What if you are using mainline 6.9.1 ?

@The9Cat I tried what you proposed and nothing.

What catches my attention is that when doing v4l2-ctl --list-devices I get only one device (and not the 3 that appear in the blog post I sent before):

$ v4l2-ctl --list-devices

Intel MIPI Camera (platform:v4l2loopback-000):

Thanks. But this caused my trackpad to not work and a few issues with the screen itself. Rolled back to 6.8.0-31.

That's strange. My understanding is that this noble-proposed kernel set applies the patches from this site (https://github.com/intel/ipu6-drivers) to the standard Ubuntu 6.8.0 kernel source. So I'm surprised that this breaks things for @heredia21 . Sorry about that.

One could try one of the methods in the README for the 6.9.1 mainline.

I'm prepared to wait for maintainer support, myself.

[The9Cat]

@rmasad I'm mystified. You rebooted to the new kernel and nothing? When you say 'nothing', what did you try? For example, Camera (a.k.a. gnome-snapshot) detects the devices but doesn't work for any device for me; not even a uvc camera. I should attempt to troubleshoot that. Separate issue.

Seems to me that your system must have configured the camera at some level or you would not see anything in v4l2. Did you check your dmesg to see if it found the ipu6 stuff? E.g. sudo grep ipu6 /var/log/dmesg? I see:

@The9Cat the output of sudo grep ipu6 /var/log/dmesg is:

[The9Cat]

That's strange. I thought that issue was fixed in the latest source but maybe not. I had to copy /lib/firmware/intel/ipu/ipu6ep_fw.bin.zst to /lib/firmware/intel . Maybe do that and try again?
