ipu6 v4l2 devices missing

[avanisubbiah]

The previous output of the command v4l2-ctl --list-devices gave me:

ipu6 (PCI:pci:pci0000:00):
    /dev/video1

ipu6 (pci:pci0000:00):
    /dev/media0

Virtual Camera (platform:v4l2loopback-000):
    /dev/video0

But after updating to kernel 6.1.9 it now just outputs:

Virtual Camera (platform:v4l2loopback-000):
    /dev/video0

When opening any app (cheese, firefox, etc.) the light does not show up and the screen is black. However on the Linux zen kernel (6.1.9) this issue is not present with the ipu6 devices showing up as well like before.

I have tried fully uninstalling, deleting yay and pacman cache, and reinstalling but ipu6 v4l2 devices seem to only be present on the Linux zen kernel (6.1.9) and not the default Arch (6.1.9) or Clear linux (6.1.7) kernels.

Yes this is a known issue. I will open a pull request in a couple of hours that should fix it :)

I am still encountering this issue after the pull request

hi @avanishsubbiah, does dkms report any errors when building the modules in install.sh?

I get the same dkms error as in issue #11

I tried manually rerunning the commands with the --force option after installation but that didn't fix it

[avanisubbiah]

So I updated from 6.1.9 to 6.1.10 and installed got the same error that dkms installation failed but now the devices show up and the webcam works regardless

I've noticed that the installation seems to work the first time I try it on new kernels, then if anything regenerates initramfs it breaks and reinstalling it doesn't fix it. Idk, how to test this exactly.

Edit: It's still working on 6.1.11, idk how to reproduce this issue.

One of the recent linux-lts kernel updates on Arch broke this again. Current version is 6.1.39-3. It used to work on some slightly older linux-lts and linux-zen kernels, within 6.1.* but I can't remember the exact version. Also, both regular (6.4.7.arch1-3) and zen (6.4.7.zen1-3) kernel versions hit the same problem here.

Running Dell XPS 13 Plus 9320, the error is:

Wondering if anyone else on those kernel versions could reproduce the issue to confirm it's not my setup?

I am having the same issues on 6.4.11-arch2-1 again. In the past, reinstalling after each update helped, but not this time. Any ideas?

Hi @avanisubbiah,

not 100% sure if this helps, but when reinstalling on a new kernel (or after initramfs changes, as you mentioned), make sure to also remove AUR package icamerasrc-git including its build cache (for yay it's in ~/.cache/yay/icamerasrc-git). See this section in the README for more details.

[alba4k]

@stefanpartheym am still getting WARNING: erroneous pipeline: no element "icamerasrc" from test.sh (reinstalled from scratch ofc)

[stefanpartheym]

Hi @avanisubbiah and @alba4k, are you still having issues? Current state of the repository should work for kernel versions 6.5.x (probably with the workaround described in this section of the README).

[alba4k]

@stefanpartheym It does not appear to work in 6.6.1 (as I kind of expected) but it may also be tied to

I guess we will have to see

I do not have that package cached (as I had already removed it)

Edit: I don't wanna say that I'm in idiot, just saying that I might be (I had disabled it like a year ago when the driver first started not working, let's see if anything has changed)

Edit 2: No it still doesn't work, but again, that may just a be a Linux 6.6 issue (or maybe even linux-zen? too lazy to try ahah, maybe will once 6.6 is known to be supposed to work)

[stefanpartheym]

@alba4k I can confirm, the driver won't work on kernel version 6.6.1 for me too. I'll have a look into this once I have some more time.

[stefanpartheym]

Closing this one, as drivers are now working on kernel v6.6.1 too when following the steps mentioned in https://github.com/stefanpartheym/archlinux-ipu6-webcam/issues/53#issuecomment-1817579746
