Thunderbolt 3 No Devices

[max3-2]

Hi,

first of all sorry for all the issues but Im trying to get this working (perfectly) on the Vision D ATX and have stumbled across another small issue which might be related to ports and adresses.

In short, I have a CalDigit TS3 Dock on the Thunderbolt Port. I know this works, I have tested it on this machine under Windows and on another Mac (Apple original).

Under my Hack, which is pretty much the same config as this one here besides being on ATX, I see the following (in System Profiler):

• USB Devices connected to the Dock work perfectly (Audio, card reader, mouse, keeb)
• Thunderbolt drivers show up under PCI (Maple Ridge TB4, Maple Ridge USB)
• Theres an „ethernet“ element with Thunderbolt@xxx but drivers not installed
• No Dock shows under Thunderbolt tab (shows here with my macMini)
• No TB functions work: Low Transfer Speeds and Ethernet connection on Dock not recognized

Are there PCI address mapped in any of the AML files which might be off for the ATX board? I understand the MAPLE-RIDGE is for HotPlug, disabling / enabling does not help.
Is anything needed in the USB mapping AML? I don’t see the TB ports mentioned in there for the ATX Variant.

Does anyone has TB working on the ATX?

Thanks for the great work with the setup so far and thanks for any help!

So I tested more and more and can't get my head around this not working. Not only no ethernet but display support via Dock is also not working.

1. I checked my DMAR (see below) - there's no restricted regions so I guess I don't need patches.
2. VT-d is on. No issues with Bluetooth or ethernet either

3. Running pretty much the same config as here now. Tried Ethernet patches on or off no difference
4. Tried the Hotplut SSDT on or off. No change.

@SchmockLord Did you had an TB Dock (with Ethernet) running in any of your tests with this setup?

Just for fun I tried booting from an USB made from this exact Repo config. Just changed the UIDs and switched USB ports. Same issues :(

What are the chances that my dock has issues with just this TB controller and not the other Mac?

Alright now here's an update:

So this took a while but I at least tracked it down. It is the AppleIGC.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.

I'll 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...). Let my ask again @SchmockLord did you try the new 0.9.5 tag with AppleIGC on a TB dock, preferably stating which dock? Thanks! (and again thanks for the great working baseline here!)
