Kernel 6.10 released, then what?

[elhossary]

Kernel 6.10 was released yesterday, it has already integrated the IPU6 drivers. However, camera's still do not work out of the box, most probably needs further configuration. I believe this repo can be re-used to configure the cameras instead of installing the drivers for Kernel 6.10 users. I have no idea how this can be done, but I am reaching out to check if anybody interested to help.

[dffischer]

I would be happy to finally ditch the LTS kernel and a DKMS module. But I also do not get any different results with the packages from this repository on the 6.10 kernel. There is also some experimentation going on over at the Arch Linux forums, perhaps at least providing some test reports.

[Daniel-Ehrhardt]

Could it be as easy as upgrading libcamera 0.3.0-1 to 0.3.1?

From their release notes:

     - libcamera: pipeline: simple: Enable intel-ipu6 with Soft ISP
     - libcamera: pipeline: simple: Enable Soft ISP for TI CSI-RX

[elhossary]

Hopefully

[Daniel-Ehrhardt]

Does anybody know how long it usually takes to get the libcamera package update?

For comparison, libcamera v0.3.0 was released on Sun May 19 16:54:11 2024 +0100. The package timestamp says: May 25, 2024, 1:47 p.m. UTC

I tried building it myself from https://aur.archlinux.org/packages/libcamera-git which doesn't seem to work on-top of an existing installation.

[dffischer]

I managed to get a build of libcamera 0.3.1 from the official package by incrementing the pkgver, updating the checksums and changing the two qt5 dependencies to qt6.

Still no camera shows up on the cam utility. On the other hand, cam also does not show anything on the LTS kernel, all the while the camera still works there.

[elhossary]

I am getting this:

[DutchEllie]

I get exactly the same messages as @elhossary. Tons of camera sensors in the v4l2-ctl --list-devices output, but no usable camera in any application. cam doesn't work either.

I have manually installed the libcamera package that has been updated to 0.3.1, but no dice either. It's as if nothing changed.

I hoped that the camera would just "work" once updated to 6.10, but apparently that's asking for too much...

[elhossary]

I believe we should wait until next version libcamera comes out of testing: https://archlinux.org/packages/extra-testing/x86_64/libcamera/ Looks like new pipewire dependencies were added, which likely will solve this issue

[catwell]

@elhossary It is unlikely that it will work. The most up-to-date discussion of this is this thread: https://github.com/linux-surface/linux-surface/discussions/1354#discussioncomment-10192743

[alba4k]

tldr we have to wait for the next libcamera release, as they forgot to include the new stuff in 0.3.1 on x86 too (it is only on arm atm)

[elhossary]

as @catwell said, libcamera 0.3.1 released from testing but still camera does not work

[sigboe]

@elhossary libcamera-0.3.2-1 was released Sep 24th, still not working

[elhossary]

yes, not working :( Hopefully it will work with kernel 6.11

[elhossary]

No luck on 6.11.1 :( That's really too much pain

[apognu]

Still doesn't work, but for the first time, I have no more errors in dmesg and my sensor is recognized.

It was not under 6.10 and full of errors.

EDIT: all of the Intel IPU6 repositories have been updated two to four days ago, so I'll try building everything again, just in case. EDIT 2: nope, still doesn't work. :(

[elhossary]

That's my output with Kernel 6.11.1 and libcamera 0.3.2.1

[stefanpartheym]

Uff this so tedious… It's 2024 and a damn webcam still doesn't work. Anyways, I updated the README to reflect the current state.

Just as an attempt to help you guys: I'm still on the LTS kernel (6.6.56-1-lts) and camera works for me using this repo for now.

[alba4k]

Has anybody checked what the latest working kernel is?

6.6.30 or so are known as working but newer lts kernels dont

[stefanpartheym]

@alba4k I just updated the README and added kernel version 6.6.56-1-lts to be working.

[alba4k]

@stefanpartheym are you sure it works? latest lts did notbfor me last time I tried

[sigboe]

@alba4k I can't comfirm 100%, but I switched to NixOS this month, and the official NixOS module to work on 6.6.54. And thats not the newest kernel driver.

[bjesus]

I've posted some instructions on how I got it working with the latest Arch kernel in the forum thread.

[elhossary]

@bjesus Great to hear, would be even better to package that in a repo like this one

[bjesus]

@elhossary there's nothing new to package, the whole thing is now natively supported.

[apognu]

Unfortunately, this is exactly what I have, and no dice for me. Which sensor do you have?

Thanks for reporting, though.

[bjesus]

ov2740 on the Yoga X1 Gen 7. What part of the setup isn't working for you? I wrote the post the way I did so that it would be easier for people to troubleshoot what piece is broken.

[marmistrz]

Which sensor do you have?

How can I check it? Dell Latitude 7440 here

[bjesus]

Running cam -l should show it.

[marmistrz]

Running cam -l should show it.

It doesn't, the error message is No sensor found for /dev/media0. Detailed log:

Looks like libcamera has no support for my sensor - a patch similar to this one should do the trick, but first I'd need to figure out what the sensor model actually is.

[apognu]

Same here.

@bjesus: The kernel seems to detect everything properly:

Okay, so my sensor (according to dmesg) is OVTI02C1:00. I tried the following patch to libcamera-git, but no success either

[bjesus]

Yeah, I don't think either of your sensors is supported, which is why it doesn't work.

[marmistrz]

@bjesus how could I add support for my sensor? See my naive approach above. I have absolutely no idea what unitCellSize should be, I just put a random value - but if it were wrong I would expect the sensor to be detected but something fail later. Unfortunately, I can't find a data sheet for ovti02c1 anywhere.

[bjesus]

I have no idea really. I think you should seek help at the https://github.com/intel/ipu6-drivers and/or the libcamera project. This thread, as far as I understood, is about the sensors for which support was added in kernel 6.10, which doesn't seem to include your device.

[bjesus]

@marmistrz I believe this blogpost https://hansdegoede.dreamwidth.org/28841.html is quite relevant for those with unsupported sensors.

[elhossary]

@bjesus I confirm that your solution in the forum thread WORKS in my X1 Carbon 10th gen with gstreamer command Thank you very much I only installed the packages without ivsc and added the line to camera.rules Then it worked right away without rebooting But it does not work on any other app, neither in web browser not zoom

[bjesus]

I don't think Zoom works with pipewire. I wrote the post in such a way that should help you understand where the problem is. Does GNOME Snapshot work? Did you change the about:config setting in Firefox?

[struan-robertson]

Annoyingly this only seems to work ~30% of the time for me, so I will have to stick to the previous solution. Hopefully soon it will be fixed an I can stop using LTS kernels on my laptop :). Just as a heads up to people trying this, setting media.webrtc.camera.allow-pipewirein Firefox stops it from reading non-pipewire cameras, so you will have to disable it to use the v4l2loopback based solution in this repo.
