2 years ago Further updates. I wrote an AUR package and made it available in gitlab that compiles the kernel using your patches and the method described in the repo readme here. FYI, I don't completely understand the current division between this repo and the ivsc-driver, I understand the ivsc code was merged into this repo? The kernel build does not currently apply the changes in that repo.
Booting from this modified kernel and attempting to load the correct modules as described above results in the same hang and the following stack trace can be found in the dmesg logs:

Hi all. Thank you for supporting this hardware on an open source OS. It's beyond appreciated. I've attempted to build your software/DKMS drivers on Arch linux for the Alder Lake IPU6 with the OV2740 sensor. Using the most recently available git packages, I'm unable to load the intel-ipu6-psys and intel-ipu6-isys modules. modprobe for intel-ipu6 itself loads the module and after this I'm able to load the ov2740 module but not with the psys/isys modules.
I'm uncertain what other feedback to provide as with the module hang I've been unable to get further debug information. I would be very happy to provide any feedback you need to troubleshoot.
Also, are you able to comment on the "intel_iommu=off" kernel option? Is this necessary?
Take care.
