New versions of upstream dependencies break the driver.

[danielksato]

I just recently tried to update to some of the latest upstream releases that purport to include support for kernels 6.7 and 6.8. All I succeeded in doing was breaking everything!

I was able to get my webcam working again by following the steps in #77 to use icamerasrc-git-fix.old. I added the prepare section to its PKGBUILD, as well as intel-ipu6ep-hal-git.

In addition, I had to pin the version of intel-ipu6ep-hal-git to commit da2e2821244f21b95bcb37a1271bf73360c4669e, and the version of intel-ipu6-dkms-git to commit cfb7af1e50a9f04e06d6bb77ea2340eb78350859.

This got me up and running again too. As a bonus, Cheese works for me now, where it didn't before.

Kindly, Can you make a pull request for it?

[danielksato]

I'm not sure if codifying this workaround is the way to go, since there's been a lot of activity upstream and I'm hoping working kernel 6.7+ support is right around the corner. But that's a question for the maintainers, I suppose; I'll try to make a PR tonight. I'll need to figure out how to use a custom PKGBUILD for intel-ipu6-dkms-git since right now we're using the one from the AUR.

[elhossary]

In principle, this repo itself a wokaround for IPU6 cameras, as these cams are not working out of the box. It is crazy how fragile the drivers and the setup are on each update.
I suggested that to have at least something known to work, may be the maintainers make another branch out of your pull request.
I will personally clone the PR to have my cam working.
Thanks in advance BTW

@elhossary I submitted a PR if you wanna take a peek. I copied the edited PKGBUILD from my AUR helper and edited it to reflect the conflict it creates between my intel-ipu6-dkms-git package and the AUR version. However, I don't really want test it locally since it might mean breaking a working install :D

[elhossary]

@danielksato Thank you for the PR. I will test that

I also ran into this build issue

I also needed to add PKG_CONFIG_PATH=/usr/lib/ipu_adl/pkgconfig/, otherwise ia_imaging was not found by CMake.

Same issues as before, you need to restart v4l2-relayd.service a few times until it works, and sometimes if you boot and the camera is not responding, you need a couple reboots for it to wake up
