Support Intel IPU6 MIPI camera on Alder Lake platforms

[You-Sheng Yang]

========== kernel driver SRU ==========

[SRU Justification]

[Impact]

To support Intel IPU6 MIPI camera on Alder Lake platforms.

[Fix]

Initial support for Intel IPU6 MIPI camera on Tiger Lake platforms has
been addressed by bug 1921345 and 1939539. They are backported from
https://github.com/intel/ipu6-drivers.

Further works to enable IPU6 camera on Alder Lake platforms depend on a
few more fixes from same ipu6-drivers repository, as well as an extra
https://github.com/intel/ivsc-driver for Intel Vision Sensing
Controller(IVSC).

[Test Case]

This depends on an integral of enablement components inclusive of the
kernel drivers that are being proposed, firmware, updates for the
userspace camera hardware abstration layer library and a gstreamer
element as what we have for Tiger Lake platforms.

[Where problems could occur]

It's confirmed Intel IPU6 MIPI camera doesn't support suspend at
streaming.

[Other Info]

Jammy is planned, but yet the support for 5.15 kernel is not yet started
from Intel side.

========== linux-firmware SRU ==========

[SRU Justification]

[Impact]

Intel IPU6 MIPI camera on Alder Lake platform takes a different fw blob.

[Fix]

While Intel has no intention to upstream IPU6 driver before kernel
camera is out, it's available in
https://github.com/intel/ipu6-camera-bins commit e60fae2b5128 from its
main branch.

[Test Case]

This would take both kernel and firmware fixes, as well as updates for
the userspace middleware, gstreamer element plugin, to enable the device.
With all of them in position, one should be able to browse camera with
legacy camera apps like cheese.

[Where problems could occur]

It's confirmed Intel IPU6 MIPI camera doesn't support suspend at
streaming.

========== original bug report ==========

This depends on following componenets:
* ipu6ep firmware in https://github.com/intel/ipu6-camera-bins/commit/e60fae2b5128cf5b8b948b234dab28e58c93877d
* Intel VSC fw version 1.2.3.439 (not yet available publicly)

[You-Sheng Yang (vicamo)]

Also tested ipu6/ivsc dkms driver from bug against Jammy 5.15, created kernel branch https://code.launchpad.net/~vicamo/+git/ubuntu-kernel/+ref/bug-1972106/build-mipi-ipu6-dkms/jammy. The results are identical to 5.17.0-9004-oem (backport ipu6/ivsc drivers into kernel) as expected.

[You-Sheng Yang (vicamo)]

Filed https://github.com/intel/ipu6-drivers/issues/19 to keep track of TGL sensors problem.

As for oem-5.17+DKMS on AndrewsMLK, the stall can be reproduced with oem-5.17 version 5.17.0-1004.4, so it's irrelevant to ipu6 so far.

Hi all and thank you for you work!

I have the new Dell XPS 13 Plus (9320) withe the Alder Lake platform:
https://ubuntu.com/certified/202112-29761/20.04%20LTS

I have installed the latest Ubuntu 22.04 plus all the available update, so my system is now:
Linux xps 5.15.0-40-generic #43-Ubuntu SMP Wed Jun 15 12:54:21 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

According to the previous message in this conversation, if I understand correctly, the webcam should work in this version, but unfortunately it doesn't, as shows the attached screenshot of Cheese.

I've also tried these steps:

$ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
$ sudo apt install libcamhal-ipu6ep0

But it didn't help.

Would you think that the driver needs more work, or that it might be an issue on my side?

Cheers,
Alex

Reply #52,

Could you try if my pipewire gst plug-in helps the issue?

Thanks,

[Shih-Yuan Lee (fourdollars)]

@Alex,

Could you open https://webcamtests.com by Mozilla Firefox or Google Chrome to check if the webcam works or not on your Dell XPS 13 Plus (9320)?

[Alex (alex-wa)]

Hi and thank you for your answers.

@Shih-Yuan Lee, wow! My webcam actually works on Firefox and Chrome! That's interesting because I remember testing it before and it wasn't working... something must have been updated since then. It's still not working on Cheese though.

@Kai-Chuan Hsieh, it didn't work, but it did make a difference. Before following your instructions, Cheese was displaying the error message visible in the screenshot attached to my previous message, and the little white LED placed next to the webcam above the screen, was staying OFF. (And this was still the case after having tested the webcam in Firefox and Chrome successfully.) After having followed your instructions, Cheese is now just showing a black screen, and the white LED is illuminated. So there's definitely an improvement. (I know that the webcam does infrared as well, could it be that Cheese tries to show the IR stream instead of the normal one?)

Having my webcam working on Chrome was the biggest thing to me, so I'm good now, thanks guys! However, I stay available of course if you'd like me to test anything.

Cheers,

[Kai-Chuan Hsieh (kchsieh)]

Hello, I am running 5.15.0-40-generic #43-Ubuntu on a Dell Inc. XPS 9320/0P9FNW, BIOS 1.3.0 04/19/2022 and the camera does not work. The XPS was delivered with ubuntu and the camera worked. I installed a standard Ubuntu 22.04 LTS and now cannot find a working set of packages. What can I try? Thank you!

Hi Stuart,

I can see a difference between your machine and mine: I updated my BIOS to 1.4.0. However, I don't really think that this makes a difference... but if you want to update yours, see this link:
https://www.dell.com/support/home/en-au/product-support/product/xps-13-9320-laptop/drivers

Note that my machine was delivered with Windows on it (only because Dell doesn't offer Ubuntu for users in Australia, and refuses to provide their Ubuntu ISO, even when you pay for "premium support"), and I used the Dell utilities provided on Windows to update my BIOS. But according to Dell, you can do it from Ubuntu as well.

Cheers,

(@Kai-Chuan Hsieh, I'll check what you asked during the weekend ;-))

[Stuart Pook (slp110264)]

hi Alex, can you give me the output of "dpkg -l" (edited if you prefer)? I guess that you do not know if the webcam was working with firefox & chromium before you installed libcamhal-ipu6ep0. I doubt that upgrading the BIOS will help especially as the webcam was working before.

[Alex (alex-wa)]

I'll give you that tomorrow ;-)
Yeah, agree with the BIOS.

[Shih-Yuan Lee (fourdollars)]

FYI: Regarding the Cheese issue, there is another bug, i.e LP: #1978757, to deal with it.

[Alex (alex-wa)]

Hey guys,

@Kai-Chuan Hsieh, `gstreamer1.0-clutter-3.0` is indeed at the latest version on my machine: `3.0.27-2ubuntu1`

@Stuart, I attached the full output of `dpkg -l`. Comparing it with yours using Meld, they are quite a few differences.

hi all, I didn't change anything except rebooting and now my webcam works in both firefox and chromium on https://webcamtests.com. Cheese takes a minute or so to display "There was an error playing video from the webcam" and say:

../src/intel/isl/isl.c:2216: FINISHME: ../src/intel/isl/isl.c:isl_surf_supports_ccs: CCS for 3D textures is disabled, but a workaround is available.

The v4l2-relayd unit works.

The above test (where the webcam worked) was with 5.15.0-40-generic (5.15.0-40.43). With 5.17.0-1012-oem #13-Ubuntu, gst-launch-1.0, firefox and chromium detect and can open the webcam but fail. Chromium says "The video track in paused". Firefox says the webcam shows a one-color filling, it streams video as a static image and has low frame rate. "GST_DEBUG=2,v4l2src:5 gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! xvimagesink" hangs with a black window while saying:

Reply #65,

Hello,

Can I have your dmi product_sku info by $ cat /sys/class/dmi/id/product_sku?
The product sku we support for XPS 9320 is 0AF3

By the way, does $ gst-launch-1.0 v4l2src ! videoconvert ! glimagesink work?

Thanks,

[Stuart Pook (slp110264)]

hello, I confirm that an install of Ubuntu 22.04 LTS followed by "sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6 && sudo apt install libcamhal-ipu6ep0 && sudo reboot" is enough to get the webcam working with firefox, chromium and "gst-launch-1.0 v4l2src ! videoconvert ! glimagesink". Cheese does not work:

Hi all, glad to read that your camera is working, Stuart!

My product_sku is also 0AF3.

[Norbert Schuch (nschuch)]

Hello,

I am having issues which look similar to those reported by Stuart in getting to run the Camera on a Lenovo X1 Gen10. (But unfortunately, rebooting did not help.) The camera shows up in gst-device-monitor as "ipu6" with unreasonable parameters, and gst-launch complains about 2:0:0:0 colorimetry.

This behavior is observed both in Ubuntu 22.04 with the default kernel 5.15.0-40 and in Ubuntu/Debian with a self-compiled kernel 5.18.9 with the ipu6/ivsc modules included (with small variations, the 5.18.9 does not manage to bring up the relayd, and no test device is present; and under 5.15, gst-device-monitor only reports the ipu6 device for root).

Any help is very much appreciated -- thank you! Let me know what other information to supply.

To start with, here's what I see for the default 5.15.0-40 kernel + ipu6 packages:

Ubuntu is only supporting Intel MIPI camera for few Dell laptops via OEM enablement process.
Please check https://wiki.ubuntu.com/Dell for details.
We are working on supporting more Dell laptops for Intel MIPI camera.

Intel MIPI camera on Ubuntu Linux needs the works of BIOS/firmwares, kernel and userspace from Intel.
It needs the PC vendors such as Dell, HP, Lenovo, ..., to request the support from Intel.

[David Burke (bufke)]

The XPS 13 Plus 9320 webcam does not work for me since upgrading to 22.04 from the original 20.04 OEM installation.

BIOS: 1.4.0
Kernel:5.17.0-1013-oem
libcamhal-ipu6ep0 is installed from the mentioned PPA
v4l2-ctl --list-devices
Intel MIPI Camera (platform:v4l2loopback-000):
 /dev/video0

Neither chrome nor Firefox show video. Similar to the issue described here https://askubuntu.com/questions/1414767/dell-xps-plus-9320-webcam-not-detected-in-ubuntu-22-04?atw=1#comment2465343_1417193

[Kai-Chuan Hsieh (kchsieh)]

@bufke

Hello,

May I know how you upgrade ubuntu from 20.04 oem to 22.04? by $ do-release-upgrade or $ sudo apt dist-upgrade. I am curious how you have 5.17.0-1013-oem installed.

May I know if you keep using 5.14.0-10XX-oem, does it work for webcamtest or any application utilize camera by browser?

Thanks,

[Andy Chi (andch)]

@bufke,
Can you help to provide logs from /var/log and `dpkg -l`?
I also tried one 9320 and do-release-upgrade to Jammy. I didn't install 5.17 after do-release-upgrade.

[David Burke (bufke)]

I upgraded via do-release-upgrade -d

With 5.15.0-41-generic the webcam works! At least in Chrome/Firefox. However wifi becomes unreliable and disconnects after some time. I will confirm that this is reproducible later. For now, it doesn't look like a viable solution for me.

I had installed the 22.04 oem kernel, assuming it would be better, as the oem 20.04 install was using an oem kernel.

Is there any advantage of using 5.14.0-10XX-oem instead of 5.15 generic? How would I install it?

Let me know if more logs would be helpful.

[Kai-Chuan Hsieh (kchsieh)]

@bufke

You can try install linux-modules-iwlwifi-generic to see if it can improve your wifi experience, and the linux-firmware should be up-to-date too. If it doesn't help, please open another bug for it.

The patches that in oem kernel 5.14.0-10xx-oem for your platform should be in 5.15.0-xx-generic too, there is no advantage for using 5.14 oem kernel.

Also, the XPS 9320 plus has certified by 5.15 generic kernel. Please keep on this track and report issue on it, thanks.

I just got a new XPS 13 plus 9320 and it came with Windows 11. I replaced it with Ubuntu 22.04, but the Webcam wasn't working so I replaced that with Ubuntu 20.04, but the webcam still doesn't seem to be working. I tried:

$ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
$ sudo apt install libcamhal-ipu6ep0

And now Firefox can detect it but https://webcamtests.com/ and Cheese just show a black screen. I'm pretty sure the hardware is fine since I tested it when it still had Windows 11 and it was running fine. I'm also fairly new to Linux so I feel like I just didn't install something, but anyone know what could be up with this?

[Kai-Chuan Hsieh (kchsieh)]

@hobble

When you install 22.04 stock Ubuntu please enable the oem meta in software-properties-gtk > additional drivers, then do the full dist-upgrade by $ sudo apt dist-upgrade. Please also make sure the BIOS is the latest,https://www.dell.com/support/home/zh-tw/product-support/product/xps-13-9320-laptop/drivers. You can upgrade the BIOS by exe file or run $ sudo fwupdmgr update. If it is still black in webcamtest, please attach kernel log and $ apt list --installed or $ dpkg-query -W, so that I can check it for you.

[Edward Wong (hobble)]

@kchsieh

I tried doing what you said by enabling the oem meta then upgrading the distro, but I'm still getting a black screen with the webcam. I also ran $ dpkg-query -W and here are the results:

Hello,

The comment #79 is for 22.04 Ubuntu. The instructions for 20.04 can be found here [1].
Please make sure which Ubuntu codename you've installed.

Did you see the camera lighted up when you open it in webcamtest? Can you attach your kernel log $ journalctl -k -b and $ cat /sys/class/dmi/id/product_sku

The packages are all installed properly. Have you tried oem image from Dell's website? If it doesn't work within Dell's oem image, I think you can request Dell to check the hardware.

https://www.dell.com/community/XPS/Can-t-download-XPS-13-Plus-Recovery-Image-Ubuntu/td-p/8218080

[Edward Wong (hobble)]

@kchsieh

No, the webcam light doesn't turn on even on webcamtest. I don't think I have tried the oem image from Dell's website. Do you think you could attach a link to it? I can't seem to find it. I ran $ journalctl -k -b and the results of this are attached in "results.txt". I also ran $ cat /sys/class/dmi/id/product_sku and this was the result: 0AF3

Thanks.

You're a genius. Turns out I just needed to reset the BIOS to default settings!

[Alex (alex-wa)]

Hi again everyone,

The camera on my XPS 13 Plus (9320) has been working well for more than two months, but it looks like the recent update of `libipu6ep`, `ibcamhal-ipu6ep0`, `libcamhal-ipu6ep-common`, `gstreamer1.0-icamera`, and/or `libgsticamerainterface-1.0-1` broke it.

On https://webcamtests.com/, the webcam LED turns ON briefly then turns OFF again, and I receive the message `The video track is paused.`. Cheese displays `There was an error playing video from the webcam`.

Anyone else having this issue? Any idea about how to fix it?

The versions installed are:

```
libipu6ep_0~git202209170647.d30e6eb-1~ubuntu22.04.1_amd64.deb
libcamhal-ipu6ep0_0~git202209170647.115a04b~ubuntu22.04.2_amd64.deb

Cheers,

[Shih-Yuan Lee (fourdollars)]

Dell XPS 13 Plus (9320) is a certified platform for Ubuntu 20.04 and Ubuntu 22.04 now.
Please don't use ppa:oem-solutions-group/intel-ipu6.
Please remove those packages from ppa:oem-solutions-group/intel-ipu6, and then install oem-somerville-tentacool-meta from Ubuntu archive instead.
ppa:oem-solutions-group/intel-ipu6 is a development PPA for Intel IPU6 camera support.

[Alex (alex-wa)]

Wow, thanks so much to both of you for your quick and effective replies. My camera is working again.

Your work and your help are greatly appreciated.

Note for anyone in the same situation: it appears that removing the packages from `ppa:oem-solutions-group/intel-ipu6` automatically triggers the installation of packages from `oem-somerville-tentacool-meta` (my log of `apt remove` contains some `Selecting previously unselected package ...`, it's the first time I see this kind of thing, I believe). However, running `apt autoremove` uninstalls the newly installed packages from `oem-somerville-tentacool-meta`. So I manually reinstalled `libcamhal-ipu6ep0` with all its dependencies, restarted my machine, and all works well now.

Cheers,
Alex

Hi @slp110264,
Just noticed that your oem-somerville-tentacool-meta is not the newest.
Can you help to try update that package?

$ sudo apt install oem-somerville-tentacool-meta

The newest version is 22.04ubuntu5, and XPS 9320 won't need to add ppa:oem-solutions-group/intel-ipu6 to install libcamhal-ipu6ep0.

oem-somerville-tentacool-meta recommends the library of mipi camera, it'll install them automatically when you update oem-somerville-tentacool-meta.

reply #101,

The package oem-somerville-tentacool-meta will install another source list /etc/apt/sources.list.d/oem-somerville-tantacool-meta.list. when you do the $ sudo apt update, it should update packages in dell.archive.canonical.com. after $ sudo apt install oem-somerville-tentacool-meta, it will update to a new oem-somerville-tentacool-meta here [1].

Did you disable other source list in you environment?

 I believe it could help with this information, but we need package these akmod-intel-ipu6,ipu6-camera-bins, ipu6-camera-hal, gstreamer1-plugins-icamerasrc and akmod-v4l2loopback + v4l2-relayd.

reply #107 #108,

Hello,

I think the hardware info in your system has problem.

Aug 30 00:01:18 binli-ThinkPad-X1-Carbon-Gen-10 kernel: ov2740 i2c-INT3474:01: chip id mismatch: 2740!=0

May I know if the MIPI camera working under windows?

Thanks,

@kc,

 For #109, Gabriel tried the windows last year, but he remember he never made the mipi work before. Thanks!

hi all, the webcam on my Dell XPS 9320 was working until this week. I just did the standard required system upgrades and it has stopped working. zbarcam shows an empty black image. cheese pauses before showing "There was an error playing video from the webcam". Chromium https://webcamtests.com/ detects my Intel MIPI Camera but after I click on "Test my cam" I get the error: "The video track is paused." What should I check?

@Stuart Pook (slp110264)

Please DON'T use ppa:oem-solutions-group/intel-ipu6 because it is a development PPA that it will often break the MIPI camera during the development.

You can use `sudo add-apt-repository --remove ppa:oem-solutions-group/intel-ipu6` to remove it.

However there may still be some broken packages in your system that you need to downgrade/remove them manually.

The simple way is to reinstall Ubuntu 22.04.3 on your Dell XPS 13 9320 again and upgrade the whole system to the latest.

[Stuart Pook (slp110264)]

thanks @Shih-Yuan Lee, I did (more or less)

sudo add-apt-repository --remove ppa:oem-solutions-group/intel-ipu6
sudo apt remove libcamhal-ipu6ep0 linux-modules-ipu6-generic-hwe-22.04 linux-modules-ivsc-generic-hwe-22.04 oem-somerville-tentacool-meta libcanberra-gtk0 v4l2-relayd libcamhal-ipu6ep0 libipu6ep libcamhal-ipu6ep-common
sudo apt autoremove
sudo apt install oem-somerville-tentacool-meta

and my webcam is working again.

ON ThinkPad X1 Carbon Gen 10, the mipi works fine now on 22.04 with genericc kernel or 6.1.0-oem kernel, tested in gst-launch-1.0 or https://webcamtests.com/ .

$ sudo apt install libcamhal0
$ sudo reboot

$ gst-launch-1.0 v4l2src ! glimagesink

Please be aware to remove ppa from source list after you install the working packages on your system.
It is because the ppa will keep updating packages from upstream, sometimes it might break your system since upstream didn't validate on all systems when they commit new code drop.

[Bin Li (binli)]

ON ThinkPad X1 Carbon Gen 11(8086:a75d), the mipi works fine now on 22.04 with generic kernel or 6.1.0-oem kernel, tested in gst-launch-1.0, it works fine.

I found it the gst-plugin-scanner crashed after install libcamhal0 , and I met this issue on X1 Carbon Gen 10(8086:465d) too.

[Nacho Mg (nacho-mg)]

After a bit of a fight, I've managed to get the MIPI camera working on my Lenovo ThinkPad X1 Carbon Gen 10. Here's what I've got:

- I'm using Ubuntu 22.04.3 LTS.
- I'm using Kernel 6.2.0-34-generic (with 6.2.0-35-generic for example it doesn't work for me)

With the above, I followed these steps: https://wiki.ubuntu.com/Lenovo

And I have added these configurations (replacing what is there, if any):

- In the file /etc/modprobe.d/v4l2loopback.conf:

options v4l2loopback card_label="Intel MIPI Camera" exclusive_caps=1 video_nr=0

- In the /etc/modprobe.d/v4l2-relayd.conf file:

options v4l2loopback exclusive_caps=1 card_label="Intel MIPI Camera"

- In the /etc/default/v4l2-relayd file:

# GStreamer source element name:
VIDEOSRC="icamerasrc"
#SPLASHSRC="filesrc location=/.../splash.png ! pngdec ! imagefreeze num-buffers=4 ! videoscale ! videoconvert"
# Output format, width, height, and frame rate:
FORMAT=NV12
WIDTH=1280
HEIGHT=720
FRAMERATE=30/1
# Virtual video device name:
CARD_LABEL="Intel MIPI Camera"
# Extra options to pass to v4l2-relayd:
#EXTRA_OPTS=-d

With this, after rebooting the system, the camera usually works in both chrome and firefox (meet, zoom, webcam test, etc...).

- In Cheese, I can also get it to work by launching it this way:

sudo cheese -d "Intel MIPI Camera".

- Sometimes when a black screen appears, just restart the v4l2-relayd service:

sudo systemctl restart v4l2-relayd.service

I hope this helps someone
