Things finally work here with Gnome Snapshot after upgrading everything to the latest (I don't have any testing repo enabled). The one thing I was missing is the `pipewire-libcamera` package.

Do you have any AUR packages installed? Like
intel-ipu6-camera-hal-git
intel-ipu6ep-camera-hal-git
intel-ipu6-dkms-git
intel-ipu6-camera-bin

Because my system is up to date and I can't use the cam so far.

bjesus · 2024-10-09 06:43:52

I don't have any of these packages installed. I did however add `KERNEL=="udmabuf", TAG+="uaccess"` to /usr/lib/udev/rules.d/70-uaccess.rules at line 37 , but AFAIK this was everything.

Interesting, even if I add that line to the file I cannot get any images from the camera. However, the camera is now at least recognized by qcam. Cheese sees the camera as well as long as I don't run it as sudo, however no image is generated. Running it as user, it lists a whole bunch of ipu6 cameras, but none of them works as far as I tried. Snapshot does not see the camera, as does chromium or firefox.

cam -l returns:

[1:28:45.094923185] [185032] ERROR IPAModule ipa_module.cpp:171 Symbol ipaModuleInfo not found

Edit: I have no idea why but the camera recognition reported above was only temporary. I was not able to reconstruct it, as of now my system does not find the camera any more.

After updating to the latest kernel (6.11.3), I see some kind of progress (although the cam is still not working).

cam -l now recognizes the camera (but still shows error messages):

$ cam -l

It would appear that there's some variation on platforms with how sensors are connected. My platform reports as

DMI: Dell Inc. Latitude 7440/04F65R, BIOS 1.9.1 11/07/2023

on

6.11.3-arch1-1

. The relevant error messages in dmesg are:

kernel: intel-ipu6 0000:00:05.0: IPU6 in secure mode touch 0x0 mask 0x0
kernel: intel-ipu6 0000:00:05.0: FW version: 20230925

kernel: vsc-tp spi-INTC1009:00: probe with driver vsc-tp failed with error -22

I can't quite figure out the topology of how things are connected, but the int3472 driver error would seem to be relevant.

The line

I got the same error because the firmware was stored on an encrypted device. I fixed it by adding the complete path to the firmware in FILES array of mkinitcpio.conf (and generate again the image). I don't know wether it is a valid solution, but the firmware is now loaded.

Did you do something else ? I'm on the exact same situation and adding the complete path of the firmware in FILES array didn't change anything (even after image regeneration).

I was able to get this working on an Ubuntu 24. Details are here: https://github.com/intel/ipu6-drivers/issues/223

bjesus · 2024-10-27 08:11:04

Finally got the whole thing working on Arch.

From what I understand, you need to make sure libcamera is working properly, and then it's up to either gstreamer or pipewire to make it usable in other apps, e.g. Firefox.

First, make sure your sensor is supported in the mainline kernel (ov2740, ov01a10, hi556). If it isn't, I suggest reading Hans blogpost https://hansdegoede.dreamwidth.org/28841.html , as you might be able to help him with getting your sensor supported upstream.

These are the packages I have installed that I think are relevant:

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

I'm not sure the last one is actually needed. I'm running the latest Arch kernel, 6.11.5-arch1-1. I do not have any package with "ipu6" in its name.

I also created a file at /etc/udev/rules.d/camera.rules with this line in it:

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

The first step is to see if libcamera is working. I've checked using the libcamera util:

cam -c 1 -F'#.bin' -C

This should generate a lot of files (stop it after a second with Ctrl+C) and turn on the camera light if everything is working correctly. If it isn't, libcamera is probably not working correctly and there's no point in trying to get pipewire or gstreamer to work, because they all depend on this. If it's working with sudo, it means there's some permissions issue. Make sure you created that camera.rules file and rebooted.

Once you got libcamera working, you can test gsteamer like this:

gst-launch-1.0 libcamerasrc ! queue ! glimagesink

This should be the first time you actually see an image from your camera. Hooray! If it isn't working, try with sudo. If it's working with sudo, probably the camera.rules file isn't applied. Try restarting.

Now that our camera is working with gstreamer, let's check it with pipewire. You can try it in "GNOME Snapshot" (extra/snapshot). This can be a little tricky as I think it depends on some desktop portal to ask for camera permissions, so make sure you're running a modern and well-configured desktop environment (you need to have xdg-desktop-portal-* configured and running).

If this is working, the last step you'd probably want is to have it running in Firefox. Make sure media.webrtc.camera.allow-pipewire is set to true in about:config, restart Firefox, and test your camera here: https://mozilla.github.io/webrtc-landing/gum_test.html. I've tested with extra/firefox-developer-edition 132.0b9-1, and it's working fine also using video chatting services like Google Meet.

Hope this is useful for some!

Lacking the skill to fiddle with code I probably just wait and watch :oS

Glad the first step worked for you ! I can't get the firmware loaded in my system though, and unfortunately I have no clue on what is going on.

For the record: I did not give mkinitcpio any path information to the firmware files, the firmware seems to be loaded without the help of paths in mkinitcpio.conf. I don't know how your system is encrypted, but with my system the files are on the encrypted root partition which of course gets decrypted and opened during startup, and I believe the firmware is being loaded after that. Did you have a look at the supported sensors on Hans de Goede's site?

After reading your message and confirming that everything is installed (except for the `ivsc` firmware, which is included in `linux-firmware`), I added the rule `KERNEL=="udmabuf", TAG+="uaccess"` to `/etc/udev/rules.d/camera.rules` on line 37, as suggested in a previous comment. I then restarted and followed the steps you provided. For the first time, my webcam worked on Firefox (tested on Google Meet). However, after closing Firefox, the entire system froze, requiring a hard reset. Unfortunately, since then, I haven’t been able to get it working again. This is quite frustrating. Currently, the `cam` command produces the following output:

$cam -c 1 -F'#.bin' -C

I'm not sure what you mean by "on line 37", this should be the whole content of the file:

$ cat /etc/udev/rules.d/camera.rules
KERNEL=="udmabuf", TAG+="uaccess"

I do have the ivsc-firmware package installed, and the default Arch kernel. I suggest trying that first. Everything is working well here, X1 Yoga Gen 7.

From what I understand, you need to make sure libcamera is working properly, and then it's up to either gstreamer or pipewire to make it usable in other apps, e.g. Firefox.

Hope this is useful for some!

Perfectly working after following these steps. Thinkpad X1 Nano G3.

Thank you!

i have a Dell Precision 5470, and have it mostly working. I can run

gst-launch-1.0 libcamerasrc ! queue ! glimagesink

and everything works fine, but snapshot / cheese or anything browser related does not work. Trying on gnome, so I'm pretty sure the xdg-desktop-portal is working.
It's soooo close.

Anyone able to get the webcam working on XPS 9340?

For the record: I did not give mkinitcpio any path information to the firmware files, the firmware seems to be loaded without the help of paths in mkinitcpio.conf. I don't know how your system is encrypted, but with my system the files are on the encrypted root partition which of course gets decrypted and opened during startup, and I believe the firmware is being loaded after that. Did you have a look at the supported sensors on Hans de Goede's site?

My system is encrypted the same way. I checked the Hans de Goede's site for my specific sensor and it seems it's not supported at the time, I guess that's it for now !

There seems to be a bug in Dell laptops : https://github.com/intel/ipu6-drivers/issues/288

On my precision 5480, if I list i2c devices, only i2c-OVTI01AB:00 is showing, which is presumably IR camera :

From what I understand, you need to make sure libcamera is working properly, and then it's up to either gstreamer or pipewire to make it usable in other apps, e.g. Firefox.
First, make sure your sensor is supported in the mainline kernel (ov2740, ov01a10, hi556). If it isn't, I suggest reading Hans blogpost https://hansdegoede.dreamwidth.org/28841.html , as you might be able to help him with getting your sensor supported upstream.
...
If this is working, the last step you'd probably want is to have it running in Firefox. Make sure media.webrtc.camera.allow-pipewire is set to true in about:config, restart Firefox, and test your camera here: https://mozilla.github.io/webrtc-landing/gum_test.html. I've tested with extra/firefox-developer-edition 132.0b9-1, and it's working fine also using video chatting services like Google Meet.
Hope this is useful for some!

I managed to get it working for the first time. It works with cheese but not on the browser. However, the picture is kinda black and white and I get this warning:

I'm on 6.11.9-arch1-1. I added the line in the rules and reloaded everything but still the same weird black and white image. Should I install v4l2loopback?

Running 6.12.1

Randomly at boot the sensor will not initialize

[   12.907351] ov2740 i2c-INT3474:01: chip id mismatch: 2740 != 0
[   12.907361] ov2740 i2c-INT3474:01: error -ENXIO: failed to find sensor

If the sensor is initialized, cheese will work fine with a slightly green shade in the video.

Firefox will show 20 different ipu6 sources, running firefox with "media.webrtc.camera.allow-pipewire: true" will not detect any webcam at all.

I have installed

pipewire-libcamera 1:1.2.7-1
pipewire-v4l2 1:1.2.7-1
v4l2loopback-dkms 0.13.2-1
libcamera 0.3.2-1
libcamera-ipa 0.3.2-1
libcamera-tools 0.3.2-1

No, did you get it working in the meantime?

This should be the first time you actually see an image from your camera. Hooray! If it isn't working, try with sudo. If it's working with sudo, probably the camera.rules file isn't applied. Try restarting.

Thanks for the instructions!
So I manage to get an image with sudo but not without sudo. (also nothing with google meet, etc ...) I did apply the udev rules.

Any clues if I could check/do something else?
