How to use the IPU6 webcam with kernel 6.10+?

amirbilu · 2024-12-05 20:03:39

Has anyone been able to make it work on Lenovo X1 carbon (Gen 12)? nothing seems to be working.
The camera is identified by v4l2-ctl, but not by cam -l

Nope. According to Hans De Goede our sensor is not supported yet https://hansdegoede.dreamwidth.org/28841.html

No, did you get it working in the meantime?

Nope, still waiting for a proper guide for this model, are using XPS 9340 too?

Ah, I actually misread your model number first. I am on a Dell 9640. But I figure much of the hardware (and issues) are similar.

I currently keep my old laptop around just for video conference, which is kinda annoying.

I am somehow hoping that the issue will resolve itself with a kernel update in the near future.

Not sure if that is too much wishful thinking ...

I had the same problem as others reported here, but I solved it, finally!. Well, except for Chrome, see below.
I have a Dell Precision 5690, Linux 6.12.1-zen kernel, KDE Plasma 6.2.4, wayland 1.23.1.
I followed the instructions of bjesus at https://bbs.archlinux.org/viewtopic.php … 7#p2204987. First I ensured that I have the following packages installed:

extra/gst-plugin-libcamera 0.3.2-1
extra/pipewire-libcamera 1:1.2.6-1
extra/libcamera-tools 0.3.2-1
extra/libcamera-ipa 0.3.2-1
extra/libcamera 0.3.2-1
aur/intel-ivsc-firmware

After I rebooted I saw that IPU6 hardware is detected:

$ sudo dmesg | grep -i ipu6

[    3.878493] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)

... // last 2 lines get repeated many times, then:

[   14.413179] intel-ipu6 0000:00:05.0: IPU6-v4[7d19] hardware version 6

So the pci device ID of the camera is 0000:00:05.0.

$ sudo dmesg | grep "pci 0000:00:05.0"

[    0.392174] pci 0000:00:05.0: [8086:7d19] type 00 class 0x048000 PCIe Root Complex Integrated Endpoint

[   14.309790] pci 0000:00:05.0: Connected 1 cameras

Thus, the camera device is found and the sensor is OVTI02E1.
But libcamera didn't find it, not even with sudo:

$ sudo cam -l

[0:18:48.273897168] [5007] ERROR IPAModule ipa_module.cpp:171 Symbol ipaModuleInfo not found

Available cameras:

After reading Hans De Goede's article I checked if the sensor OVTI02E1 is known at all. It is!. So why does it not work?!? Reading Hans' article carefully I realized that he said:

Note not all of these have upstream drivers yet. In that cases chances are that there might be a sensor driver for your sensor here.

The link points to Intel's ipu6-drivers repository. Looking at https://github.com/intel/ipu6-drivers/t … /media/i2c I saw that there is a driver for my sensor named ov02e1.c. I thought that all IPU6 drivers have been upstreamed to the linux kernel source!?! But apparently this is not the case:

$ yay -Ql linux-zen | grep "/drivers/media/i2c/ov"

This lists many drivers like "ov02a10" etc. but none for "ovti02e1" or "ov02e1". So apparently this driver from the ipu6-drivers repository hasn't been upstreamed yet. Luckily, there's an AUR:

$ yay intel-ipu6-dkms-git

Important! As of today this should build rev r205.0ad498824-1 which matches the 6.12.1 kernel. Previously I made the mistake to build an older revision r187 that doesn't compile. I had to remove the old build files before that, via:

$ rm -rf .cache/yay/intel-ipu6-dkms-git/

Btw. the AUR is flagged outdated but that's a mistake. I presume someone flagged it because he thought that all drivers have been upstreamed, but that's wrong.

Now verify that the drivers have been built and installed:

$ ls -l /var/lib/dkms/ipu6-drivers/r205.0ad498824/6.12.1-zen1-1-zen/x86_64/module/

Load the driver:

$ sudo modprobe -v ov02e10

and lo and behold libcamera now detects my camera! Even without being root:

$ cam -l

[3:11:33.424194631] [2237298] ERROR IPAModule ipa_module.cpp:171 Symbol ipaModuleInfo not found

... // lots of errors and warnings
Available cameras:
1: 'ov02e10' (\_SB_.PC00.LNK1)

The errors and warnings seem to be neglectable.
gstreamer can use the camera, too, but only with sudo:

$ sudo gst-launch-1.0 libcamerasrc ! queue ! glimagesink

For the first time I see a picture, hooray! But since it only works as root I must apply the camera udev rules, as bjesus and others explained: I created a file at /etc/udev/rules.d/camera.rules with this line in it:

KERNEL=="udmabuf", TAG+="uaccess"

After another reboot now it works without sudo.

Cheese worked out of the box.

Firefox worked after setting media.webrtc.camera.allow-pipewire = true in about:config and restarting.

For Chrome I enabled "PipeWire Camera support" in chrome://flags/#enable-webrtc-pipewire-camera. Chrome detects the camera, but all I get is a black picture. I have to investigate this further. So far nobody seems to have this problem, but I admid the combination Wayland+Plasma+Chrome+Pipewire+MIPI camera with ov02e10 sensor is very special.

I, like many other people, have suffered with this stupid camera for far too long. Deep regrets on trusting Intel to support linux as a first class citizen. That said, I was able to fix the problems in this thread. Following the instructions from dmoebius above:

dmoebius wrote:

If you can see your camera output in qcam but nothing else, you probably need to tell wireplumber to use libcamera and not v4l2. That is that the userspace wireplumber defaults to is v4l2 and the fancy ipu modules only work with libcamera. I discovered this through a blog post written by developer Jan Grulich. That's as simple as creating the file $HOME/.config/wireplumber/wireplumber.conf.d/99-libcamera.conf and putting in it:

wireplumber.profiles = {
   main = {
      monitor.v4l2 = disabled
      monitor.libcamera = optional
   }
}

Said blog post:

https://jgrulich.cz/2024/12/13/when-you … re-issues/

The good news is that there is far lower cpu usage with the in tree ipu modules and not sending it through v4l2 relay. It's a usable experience that seems to be very decent finally. Thanks to the people who put in the effort to get it here. I have the ov2740 sensor in a Thinkpad X1 Nano gen2.

Only problem is that the hardware bugs out on suspend. There might be some magic incantation of manual unloading/reloading modules that makes it work but right now my suspend won't resume unless I unload the ov2740 sensor module first. Then, after resume, I can't actually use the camera without rebooting. If anyone figures out the magic incantation do post here. I get the following error in dmesg when I try to manually unload/reload the chain of modules:

$sudo rmmod ov2740
$sudo rmmod intel_ipu6_isys
$sudo rmmod intel_ipu6
$sudo rmmod i2c_ljca

$sudo modprobe i2c_ljca
$sudo modprobe intel_ipu6

$sudo modprobe ov2740

Further info... I diffed the modules and their status from before/after suspend and it appears that something strange is happening with the intel_ipu6_isys module or intel_skl_int3472_discrete in my case. Not sure what. I'm sure someone with a better understanding of how this is all glued together could sort it out.

I'm getting my ov2740 camera to work sporadically on 6.12.1 using cheese and qcam.

Sometimes you need to reboot to be able to use the camera at all, and you might need several attempts to get qcam and cheese to show any picture.

I'm also unable to get the camera to be detected in Chromium and Firefox despite enabling the pipewire camera settings.

loiclf · 2025-01-04 14:58:08

I get it working with a Dell XPS Plus 9320 on a fresh Endeavouros install with Gnome (wayland)

$ uname -r
6.12.8-arch1-1

I installed :

libcamera 
pipewire-libcamera 
pipewire-v4l2 
v4l2loopback-dkms
extra/gst-plugin-libcamera 
extra/pipewire-libcamera 
extra/libcamera-tools 
extra/libcamera-ipa 
extra/libcamera
extra/snapshot

That's all. I reboot and it's working directly on gnome snapshot.
I just had to activate pipewire camera on firefox : navigate to about:config and switch media.webrtc.camera.allow-pipewire to true.

Stuck from more than 2 years with ubuntu on this laptop, I'm glad to be able to leave it now...

I just try again with a fresh endeavouros install with i3wm (xorg) only.

I install the same packages and it's not working in firefox even with pipewire camera allowed. It's working in snapshot. I'll try to make a fresh gnome install to try gnome xorg.

So it's working with gnome xorg and wayland.
If I install i3-wm with gnome, it's working on firefox & snapshot.

I have a modal asking Permission to access the camera the first time I open the cam in firefox or snapshot. It's the only difference. I guess there is a package installed with gnome that allow firefox to access the camera. I have to find which one.

If I install xdg-desktop-portal and xdg-desktop-gtk, when I launch firefox the modal asking for permission open and after allowing access to the webcam it's fine. I don't understand why I need this package. Is firefox sandboxed ? Maybe it's only because I use EndeavourOs. Anyway, it's working now.

Hi, everyone!! My first post here!!

I followed exactly what dmoebius showed above (thanks!!) and my camera is working on my Galaxy Book 4 Pro with Intel Ultra 7 155H. The difference was that my camera sensor is the OVTI02C1 so I'm using the ov02c10 driver.
The only thing that is kinda annoying is that, despite the camera is working, it's not calibrated so the image is kinda bad.

$ cam -l

Even uncalibrated it's working okay in snapshot and firefox (Google Meets). Cheese for some reason doesn't work, but I don't use it so it's okay.
If someone know how to fix this calibration issue, I would be really glad. Thanks!

Hmmmm. I still have the same suspend issue even on 6.12.8. I dug through the bug reports but don't see anyone else having reported it. Has anyone else here had this problem or seen a report?

I've retried this for my Dell Latitude 7440 on the 6.12 kernel:

My sensor seems to be listed as INTC100B, which doesn't seem to have a module alias.

Any clues as to how to get some kind of driver for INTC100B?

Update from Hans De Goede about thinkpad x1 carbon gen 12.
Apparently he made it to work, but these drivers need to be accepted in the kernel before that will happen out of the box.

See https://bugzilla.redhat.com/show_bug.cgi?id=2333387#c2

I got my camera working on a Thinkpad X1 Carbon Gen 13, following dmoebius instructions on this comment

Works like a charm on Firefox.

I'm also running Wayland and Plasma, and I can reproduce the issue with a black video on Chrome/Chromium.

So far, can't make it work with Slack

Hello,

has anyone tested the patches given here: https://bugzilla.redhat.com/show_bug.cgi?id=2324683#c13

I've just tested and the webcam is recognized on my Dell precision 5480 natively in Fedora 41, still not on Arch.

I'm not sure how to put these patches on the Arch kernel...

Arch Linux
