IPU6 driver does not work on XPS 9315

[gaul]

I followed the instructions at https://hansdegoede.livejournal.com/27276.html but the camera still does not work on my XPS 9315. @jwrdegoede

Ok, lets see if we can get to the bottom of this.

1. Please reboot the laptop and then immediately after the reboot run:

dmesg > dmesg.txt
lsmod > lsmod.txt
rpm -qa | grep ipu6 > ipu6-rpms.txt
ls -l /sys/bus/i2c/devices > i2c-devices.txt
ls -l /dev/video* > video-devices.txt

And then attach the generated dmesg.txt, lsmod.txt, ipu6-rpms.txt, i2c-devices.txt and video-devices.txt files here.

2. After collecting the files please try using the camera stack directly from gstreamer (instead of using the v4l2 emulation through v4l2loopback):

sudo systemctl stop v4l2-relayd.service
gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! xvimagesink

After this please:

2.1 copy and paste the output of the gst-launch-1.0 command in a comment here 2.2 run dmesg > dmesg2.txt and attach the generated dmesg2.txt file here 2.3 Add a note here if the camera worked with the gst-launch-1.0 command (or not) ?

3. Did you in the past maybe try to install the ipu6 drivers manually ?

I attached the requested output:

dmesg.txt dmesg2.txt i2c-devices.txt ipu6-rpms.txt lsmod.txt video-devices.txt

Critically there do not appear to be any video devices:

ls: cannot access '/dev/video*': No such file or directory

The gstlaunch command also fails due to this:

$ gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! xvimagesink

I never previously tried to configure the camera -- I only used the blog post instructions. However I tried these a few months ago and they didn't work and have dnf updated a few times since then.

@gaul, sorry for being a bit slow with getting back to you.

The issue seems to be that you are using secureboot and you have not generated + added a local certificate for signing locally build kernel modules like the IPU6 kernel modules:

[    5.750066] Loading of module with unavailable key is rejected
[    5.795896] Loading of module with unavailable key is rejected
etc.

There are ways to fix this:

1. Generate a local certificate and at this as a valid key to shim, see: https://rpmfusion.org/Howto/Secure%20Boot and then after this wait for the next Fedora kernel update, which will build modules which will now be signed. You can do: `dnf update 'kernel*' after following the instructions and with some luck a kernel update is already waiting.
2. Disable secureboot in your BIOS options.

Please give this a try and let me know if it helps.

2 works! Thank you for your help!
