How to use the IPU6 webcam with kernel 6.10+?

Since kernel 6.10, the IPU6 driver is included in the mainline kernel. In order to build it, one needs to use add the following option:

CONFIG_VIDEO_INTEL_IPU6=m

to the current linux-mainline AUR package. The firmware seems to already be present in the current stable linux-firmware package:

$ pacman -Ql linux-firmware | grep ipu6
linux-firmware /usr/lib/firmware/intel/ipu/ipu6_fw.bin.zst
linux-firmware /usr/lib/firmware/intel/ipu/ipu6ep_fw.bin.zst
linux-firmware /usr/lib/firmware/intel/ipu/ipu6epadln_fw.bin.zst
linux-firmware /usr/lib/firmware/intel/ipu/ipu6epmtl_fw.bin.zst
linux-firmware /usr/lib/firmware/intel/ipu/ipu6se_fw.bin.zst

v4l2 detects the ipu6 webcam:

$ v4l2-ctl --all

However, none of the /dev/video[0-31] devices seems to be usable. Do you have any idea how to make user-space applications use the camera? I have removed all the DKMS modules that I previously used with the workaround for the driver. My hardware is Dell Latitude 7440.

Re: How to use the IPU6 webcam with kernel 6.10+?

I'm looking forward to this too when 6.10 is stable. From what I've been following (https://www.phoronix.com/news/Intel-Web … 2024-State), libcamera (through PipeWire presumably) is needed but I don't know if the IPU6 patches (https://lists.libcamera.org/pipermail/l … 40113.html) have been merged. Does it show up when you run the "cam" utility from libcamera-tools?

It doesn't:

and the error that we get is irrelevant, cf. https://gitlab.freedesktop.org/pipewire … ssues/3411

The patches have been merged and are already in the version from the repo: https://git.libcamera.org/libcamera/lib … 9795e3c2d9

Re: How to use the IPU6 webcam with kernel 6.10+?

I'm at a similar point with my HP Spectre x360 14 eu0000.

I think that libcamera has to be patched to support the certain camera sensor. It`s ov08x40 in my case. There is a patch for it here.

After applying this patch the camera shows up:

$ cam -l
[22:13:46.358192419] [112232] ERROR IPAModule ipa_module.cpp:172 Symbol ipaModuleInfo not found

Available cameras:
1: Internal front camera (\_SB_.PC00.LNK0)

Maybe you can adapt this to your sensor?

The device stays unusable in any applications neverless. There must be some userspace things that are missing at the moment. A proof that the cam is working can be achieved with qcam (from libcamera-tools):

sudo qcam -s "width=1928,height=1208"

...camera is working!

Because I'm really not familiar with this midi ipu6...stuff, as I had only uvc devices in past,  i'm stuck at this point.

How can I figure what model my sensor is?

Re: How to use the IPU6 webcam with kernel 6.10+?

Hi,
I updated today and I got the 6.10.
On my Dell Latitude 9330 2in1, I  do not see any camera.
Firmware is :

Re: How to use the IPU6 webcam with kernel 6.10+?

I notice couple of little things that may be of interest - but no actual solution.

1) libcamera modules are all installed into one directory - /usr/lib/libcamera.
Means there are IPA modules and v4l2-compat modules both in same libexecdir.
libcamera seems to scan all these modules and rightly tells us that v4l2-compat is an invalid IPA module - which is correct. They therefore have nothing at all to do with the ipu6 camera question.

I assume this error is "benign" - however in my very limited view of this - I would have thought it would be better to separate v4l modules and IPA modules into 2 different directories.
There is a meson libexecdir option - but this seems to be intentionally used for both.

2) I also note that while an ipu3 module is built by default  there is no  separate ipu6 module. And after an admittedly brief check of source, I did not find any refs to ipu6 nor in any post 0.3.0 release git commit either.

3) Side comment: Our PKGBUILD is fairly complex with its efforts to split libcamera into multiple sub-packages - so I ended up making a much simpler one for my own tests which makes a single package.

4) I also checked  this libcamera bugzilla and didn't find anything there either.

5) I ran with mainline kernel and it behaves same as 6.10.

Re: How to use the IPU6 webcam with kernel 6.10+?

I'm on a ThinkPad X1 Yoga (Gen 7) and I get all the same output as Xwang. Also v4l2-ctl --list-devices lists 32 /dev/video devices, which all show up in userspace applications, none of which work. (I have no idea what that is about)

v4l2-ctl --list-devices
ipu6 ():
	/dev/video0
	/dev/video1
	/dev/video2
	/dev/video3

ipu6 (PCI:0000:00:05.0):
	/dev/media0

It feels really close!

Re: How to use the IPU6 webcam with kernel 6.10+?

I also have a ThinkPad X1 Yoga Gen 7 and the code in this repository helped me to at least make it work on the last LTS kernel: https://github.com/stefanpartheym/archlinux-ipu6-webcam Perhaps some information therein is of some merit here, too.

Re: How to use the IPU6 webcam with kernel 6.10+?

I would imagine we need to wait for libcamera 3.1 to reach the repos?

edit: probably not just that. Installing libcamera, libcamera-tools and libcamera-ipa 0.3.1 from extra-testing doesn't appear to change much.

Re: How to use the IPU6 webcam with kernel 6.10+?

They made a mistake before releasing libcamera 0.3.1: https://github.com/linux-surface/linux- … t-10195097

They didn't enable the "simple" pipeline handler for all platforms, only for ARM. This simple pipeline contains the ipu6 stuff. It's enabled now. I have downloaded the official PKGBUILD files from the ArchLinux Gitlab server and manually added the patch that's also included in that Github thread. After compiling and installing (and troubleshooting, see the thread) I got my first ever webcam output!

It's not perfect yet, or even working that well at all, but it's something!!

Re: How to use the IPU6 webcam with kernel 6.10+?

I've just rebuild libcamera-git, including the fix for the simple pipeline. Unfortunately, the camera is still not detected, saying "no sensor found for /dev/media0"

I'm running Dell Latitude 7440 2-in-1, googling suggest that the sensor is ovti02c1, but is there any way to verify it?

Re: How to use the IPU6 webcam with kernel 6.10+?

Are your permissions to /dev/udmabuf and /dev/dma_heap/system set correctly?

cam doesn't even attempt to open these files. I have an impression one needs a patch akin to https://github.com/aigilea/hp_spectre_x … mera.patch, however, I don't know where to get these values from for the sensor in my laptop.

Re: How to use the IPU6 webcam with kernel 6.10+?

Sorry to bring even more pessimism, after upgrading to 6.10, using using Dell XPS 13 Plus (9320) the camera doesn't even seem to be recognized.

Have anyone with that laptop got something else?

Sorry to bring even more pessimism, after upgrading to 6.10, using using Dell XPS 13 Plus (9320) the camera doesn't even seem to be recognized.

Have anyone with that laptop got something else?

I'm using the same laptop, the camera isn't recognized too.

Re: How to use the IPU6 webcam with kernel 6.10+?

Has the kernel 6.10+ with libcamera-0.3.1 been working now?

In my case it is still not working (the only differencse that I see are the version numbers of libcamera and driver who have been updated):

Re: How to use the IPU6 webcam with kernel 6.10+?

Reporting similar issues with a Lenovo Thinkpad Carbon X1 gen 10, a 6.11 kernel, and a version of libcamera that enables simple pipelines on all arches. It feels very close since cam shows the sensor but I can’t get any output. (See edit)

Tried to chmod 666 /dev/udmabuf and /dev/dma_heap/system without success. Cam appears on several app but does not turn on nor display any outptut. Would be glad to know if someone got this driver to work.



EDIT: Got an output working by running cheese as root, so I probably did not set permissions properly.

Re: How to use the IPU6 webcam with kernel 6.10+?

Similar problems as others with the XPS 9320 on 6.10.5. I noticed that intel_ipu6_isys is not loaded by default. Loading it manually didn't help though. The module doesn't even print a log 

$ lsmod  | grep ipu6
intel_ipu6_isys       143360  0
videobuf2_dma_contig    28672  1 intel_ipu6_isys

ipu_bridge             24576  2 intel_ipu6,intel_ipu6_isys
mc                     90112  6 v4l2_async,videodev,videobuf2_v4l2,ov01a10,intel_ipu6_isys,videobuf2_common

I noticed also that intel_ipu6_psys which was present in my last working kernel (6.5.11) is no longer available in these kernels.

Re: How to use the IPU6 webcam with kernel 6.10+?

According to this debian bug (https://bugs.debian.org/cgi-bin/bugrepo … ug=1074441), it seems that IPU6 is only fully functional with kernel 6.11. Is this the case for Archlinux?
