Webcam on Lenovo X1 Carbon Gen13 (IPU7, Nova Lake)

patkoscsaba · 2025-07-29 08:45:45

Hi there.
So the camera is not detected or working out of the box.
I figured out that it is an IPU7 - Nova Lake - camera with the sensor: OVTI08F4.

What I tried so far is:
1. Install the ipu7-... and icamerasrc AUR packages.
2. That made the ipu7 driver to load and detect the the camera according to dmesg
3. But still no camera could be found with "cam -l" or with "gst-inspect-1.0 icamerasrc"
4. Octopi/Yay kept reporting the ipu7 and icamerasrc packages and outdated even after installation and update.

Does anyone had any luck with getting this camera work on this or a similar laptop? If yes please let me know here or point me to some documentation.

PS: I read all the IPU6 related posts I could find, but nothing there helped enough to get my IPU7 camera work.

We now have the 6.17 kernel that has built-in support for IPU7.
The modules are automatically loaded:

v2l2-ctl shows the devices:

In fact I think the support is not yet complete, as I see like 33 video devices.

`cam -l` shows only my other camera, a Lenovo USB camera. The Laptop IPU7 camera is not on the list.

[csaba@csaba-laptop ~]$ cam -lp

Available cameras:

I do not know what else could I try. How take this further?
