It seems like any run of powertop --auto-tune during boot is enough to throw the sound off (playing through speakers will stop after a while). You don't need the sof kernel either, upstream works fine, but you can't use powertop --auto-tune, at least on my system. If someone has found a way around this, please do tell...

I wonder if requiring pipewire to keep it active is not enough to "solve" that (but I guess it's counter intuitive for battery life)
example how to keep it open

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

If you're on Gentoo, the fol4 overlay has ebuilds with ipu6-drivers and ivsc-driver. You still need to fix userspace and firmware yourself, but then at least you have an easy way of rebuilding modules.

They don't check if you have the required CONFIG set yet, so look out for depmod symbol errors. You might need to enable some media devices (e.g. IPU3) to make the kernel include all dependent libs in the build.

Seems like zebra-ok on github was successful in building the modules with dkms using ubuntus srpms: https://github.com/intel/ipu6-driver/is … 1191848414

So with that method of building the module, I guess there's no need for that v4l2loopback workaround. Someone should test if it works properly, I'm a bit fed up with this now...

Edit: Sorry I didn't see the previous post, I had the tab open tongue

Have you found a configuration to make the webcam work without having to run the gst-launch command manually before apps can access the camera?

How did you build the modules? After using vicamos repo and applying their patches for Ubuntu, and afterwards building first the ivsc, then the ipu6 with dkms, it worked.

Oh, indeed. Good point. I checked the module tree and found the ov01a1s module what is appearently the wrong one. Maybe I have to go back and check if I patched the sources correctly.

When you are talking about "vicamos repo" you are referring to https://github.com/vicamo/ipu6-drivers/ … inst-v5.18 ?

Thank you!

No, the reasing I said that was due to a misunderstanding. I thought it was working with the ubuntu provided drivers, but they were the same in the end.

So I still use gstreamer. I actually have started with using gstreamer for other webcams too, because cheap webcams often only give the best resolution when using codecs like MJPEG, and you can't get browsers to use that. But by using gstreamer you can convert it to something that the browser accepts, thus you end up with a video stream that is a lot better.

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

@sxw I had exactly the same output as you.

But running

journalctl -k --grep=ivsc

told me that that actually ivsc-firmware hasn't been installed properly. So instead of copying to "/lib/firmware/vsc" one should copy it "/lib/firmware/vsc/soc_a1_prod/" and add corresponding "_a1_prod" suffixes to the files. See the notice for production platform.

after that running "gst-launch" with sudo did the trick for me!

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

Hello all and thank you for efforts !

my camera currently works on my Dell XPS 13 Plus. :-)

I'm sharing my steps, maybe it could help someone else (i hope so).

1) i followed procedure described by sachkris

NB : compile linux kernel was mandatory for me, because of error with other ways tested

2) i followed feedback provided by Dell support and available here : https://bugs.launchpad.net/ubuntu/+sour … omments/40

NB : i'm not using Arch but KDE Neon (ubuntu LTS + latest KDE Plasma)

Currently i dont know what made my camera working, because i first tested dell procedure (found before Dell reply feedback) and it didn't work.

So maybe some binary copy + dell procedure + reboot could explain it.

It's in french, but i made a step by step procedure to help other Dell XPS 13 Plus owners right here : https://coder-pour-changer-de-vie.com/d … plus-9320/

NB : the bash step could help, i wrote a bash to update .Konfig and Makefiles in one step.

Have a good day !
Nicolas.

Finally, I got it!

It indeed was the ov01a10 module that was not build because I kept trying the out-of-kernel-tree build variant. Doing the in-kernel-tree variant did the trick.

Thank you very much to all of you.

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

Another post in this saga. I previously mentioned that I got sound freezes if I used powertop --auto-tune. After a series of tests, I found out that the triggering setting was if I enabled powersaving on my wifi card. Really strange. If I enable everything with powertop _except_ powersaving on my wifi, the sound doesn't freeze anymore.

Posted about it here (and the script I use for applying powertop settings is there too): https://github.com/thesofproject/linux/ … 1214373478

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

As an addendum to the sound issue - it seems like powertop --auto-tune is pretty important for this laptop in regards to S2idle - since this chipset does not have S3 suspend but S2idle, power settings for each device seems crucial for the laptop to be able to power down properly when entering S2idle mode.

So, I added that power management for wifi is enabled before entering suspend, and my updated systemd sleep script (/lib/systemd/system-sleep/webcammodules.sh) now looks like this:

#!/bin/bash
if [ "${1}" == "pre" ]; then
	# wifi
	echo 'auto' > '/sys/bus/pci/devices/0000:00:14.3/power/control'
	rmmod intel_ipu6_isys
	rmmod intel_ipu6_psys
	rmmod ov01a10
	rmmod intel_ipu6

	rmmod mei_ace
	rmmod mei_csi
	rmmod intel_vsc

elif [ "${1}" == "post" ]; then
	# wifi
	echo 'on' > '/sys/bus/pci/devices/0000:00:14.3/power/control'
	modprobe intel_vsc
	modprobe mei_csi
	modprobe mei_ace

	modprobe intel_ipu6
	modprobe intel_ipu6_isys
	modprobe intel_ipu6_psys

	modprobe ov01a10

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

I have managed to put together PKGBUILDs for all the components in the IPU6 hodgepodge, by borrowing the kprobe hack from anbox-modules-dkms-git.

Install icamerasrc-git and an ipu6-camera-hal provider and you should be getting to where I am right now.

I managed to get video using this command:

sudo -E LANG=C gst-launch-1.0 icamerasrc device-name=ov02c10-uf ! autovideoconvert ! waylandsink

However for some reason Cheese can't seem to be able to use it natively... Also I can't figure out for the life of me how to access the IR camera or lights.


PS: I should note I'm on the Latitude 9430, although I found this discussion very relevant to that laptop as well.

Install icamerasrc-git and an ipu6-camera-hal provider and you should be getting to where I am right now.

I managed to get video using this command:

sudo -E LANG=C gst-launch-1.0 icamerasrc device-name=ov02c10-uf ! autovideoconvert ! waylandsink

However for some reason Cheese can't seem to be able to use it natively... Also I can't figure out for the life of me how to access the IR camera or lights.


PS: I should note I'm on the Latitude 9430, although I found this discussion very relevant to that laptop as well.

I tested out an Ubuntu OEM image and Cheese isn't able to use the webcam natively there either, so I think that's an issue with Cheese. The webcam works in other applications like Firefox, Discord, etc.

How did you build the modules? After using vicamos repo and applying their patches for Ubuntu, and afterwards building first the ivsc, then the ipu6 with dkms, it worked.

I tried doing those steps via the AUR packages intel-ipu6ep-camera-hal-git which uses those patched files (and tried installing them manually using the out-of-kernel tree compilation steps). Yet I get the same error:

The ov01a10 module seems to be loaded here so I think this error may be coming from something else rather than a missing ov01a10 module.

Re: Dell XPS 13 Plus 9320: Camera issues (Intel IPU6 MIPI on Alder Lake)

Figured it's good to follow https://lore.kernel.org/lkml/YvnwtN1SwQ … gle.com/t/

Edit: After going through that kernel.org mailing list issue I have two feelings 1) I regret getting this laptop, 2) I better start looking into the userland drivers + gstreamer and hope to get this working with Chrome + Zoom

Tried installing this with `yay -S intel-ipu6-dkms-git`. It fails (error below) but what strikes me as odd is that it does a depmod for the wrong kernel

(2/2) Install DKMS modules
==> dkms install --no-depmod ivsc-driver/r29.99a53bd -k 6.0.0-rc6-gfea329811a7b
Deprecated feature: REMAKE_INITRD
==> depmod 6.0.0-rc6-gfea329811a7b

I have that kernel installed, but I'm running

You need to add ibt=off to your kernel parameters to allow v4l2loobpack to load with that trace.

Seems it was a different issue, I had recompiled the kernel adding some more modules and the modpost was not redone for the ipu drivers. I can now load all modules and v4l2loopback but still can't get the camera to work, at least it feels like it's getting closer, now it's userland complaining:|
