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)

On XPS 9320, the MIPI camera can work with #39 kernel + ppa:oem-solutions-group/intel-ipu6 software package.

The verification method is:

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

[Kai-Chuan Hsieh (kchsieh)]

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.

[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.

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

[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.

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?

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 inux-modules-ipu6-generic-hwe-22.04 linux-modules-ivsc-generic-hwe-22.04
$ sudo apt install linux-modules-ipu6-oem-22.04c linux-modules-ivsc-oem-22.04c
$ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
$ sudo apt install libcamhal0
$ sudo reboot

$ gst-launch-1.0 v4l2src ! glimagesink

I just found some 'Payload checksum (CRC) error', not sure if it has any risks.

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.

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.

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

I have exactly same laptop (Lenovo ThinkPad X1 Carbon Gen 10) and exactly same Ubuntu 22.04.3 LTS.

Tried to follow instructions in prev comment, but NOT suceeded.

gstreamer cmd from official wiki page yields following errors:

$ gst-launch-1.0 v4l2src ! glimagesink
