So I have tested it on both a working kernel (v6.12) and an affected kernel (mainline).

I managed to get the domain translation structures on the affected kernel, but couldn't get them on the working one since reading the file always ended up in a system crash or a segmentation fault.

I also couldn't get the PASID table entries, because the GPU doesn't support PASID.

Domain translation structures:

I've also looked through dmesg on both configurations, and on the affected kernel, this was the only data I found to have atleast something different. (On the working kernel basically nothing was reported)
