Issues with Thunderbolt Dock - Ventura

[max3.2]

Hi,

I have just set up my Hack on newest Ventura and OC 0.9.5 and by all means its working fairly good. I have attached my EFI but for the sake of the problem at hand you can always also refer to this git [1] where I took most of the ideas. This is tried and tested from what I read.
I have also booted using the git config as is and the issue described below is the same as with my attached EFI. But here we go:

Main issue is that Thunderbolt controllers show in profiler and Ioreg but my device, a Caldigit TS3 (TB3!! - can this be an issue?) dock, just connects via USB and thus won't allow display oder, most important, Ethernet no connect. I tested the same dock on dual boot Win (same machine, works) and my other macMini (original) - works too.

The issue is that the TB controller shows in System Info, see image 1. There's ethernet with no driver though. I have stable USB to the dock, see image 2. However, TB is dead, see image 3.

Ideas / What I tried...:
1) Turned Hotplug SSDT on and off
2) Checked my unpatched DMAR (no restricted memory sections, thus no patching). Added patches I found in other Repos with custom DMARs just FWIW. Both not working. (Why are there no restricted sections in my DMAR?).
3) My USB SSDT does not contain any of the TB ports. I hope that's correct, else it's working great. Its the same as in the repo for the ATX variant.
4) Checked that VT-d is on a working, see image 4. No issues with anything else (WiFi / BT) so far. Handsoff, Cont. working perfectly.

Nothing worked. So Im really clueless here - any idea helps before I have to plunge for a new docking station which I really try not to...

Thanks!

EDIT: Redacted EFI with no UUIDS

Edit: this is my unpatched (from windows, no OpenCore) DMAR:

Some more last ideas to no avail so far:

1) Patched in usb2 personality at the TB port. Thought this might be needed for some sort of handshake...
2) Updated dock FW

Ok so this took a while but I at least tracked it down. It is the AplleIGC.kext which I. had as a replacement for the i225 compatibility in upcoming Sonoma. As soon as this in there, TB ethernet breaks. TB ethernet also uses the same driver as onboard ethernet (but onboard works with AppleIGC )

I still don't get my dock as TB device but now I get ethernet on TB bus, see image attached.

Ill keep this unsolved / running if anyone has ideas or experience why the dock does not show up as TB device but the rest is working (and ethernet is mapped ob TB, too...)
