Thunderbolt Hotplug #1

Open sambow23 opened 3 days ago

Currently does not work. Using TB3 SSDT patches from multiple XPS 7590 Hackintosh repos (same hardware/mobo) do not seem to change behavior.

To get Thunderbolt 3 hardware working currently, the user must have these settings set in the BIOS: Thunderbolt Adapter Configuration
Thunderbolt ✅
Thunderbolt Boot Support ✅
No Security ✅
Thunderbolt Auto Switch
Auto Switch ❌
BIOS Assist ✅

Then the user must boot the system with the Thunderbolt peripherals attached.

Ok well uhh it seems to work? I booted my system with the TS3 Plus, unplugged the dock after macOS booted, and then replugged it and everything came back.

sambow23 commented 3 days ago

I understand now, It seems like when booting the system with no TB3 device, it leaves the controller enumerated or in a off-state. As said before, if I boot the system with my TS3 Plus plugged in, the thunderbolt controller shows under PCI in System Profiler and im free to hotplug any TB3 peripheral. Though I have not tested eGPUs just yet.

Tried a RX580 inside a Razer Core X. It sees the GPU but the drivers never load, it does work on a real mac.

Another issue, the internal display garbles out if any thunderbolt accessory is plugged in, booted with it or not. If I use a USB-C monitor a HDMI display that aren't connected to a thunderbolt device, the issue does not happen.

I was able to use TbtForcePower, which let me power on the Thunderbolt controller without a TB3 peripheral plugged in. Though I'm still having issues with the internal display freaking out. Not entirely sure where to look for this...

Doesnt seem to be thunderbolt related, also happens when I plug in a USB-C display. Disconnecting the monitor, sleeping the laptop, and then waking it seems to fix it? I can even plug the monitor back then and it works fine. Guess I will need to look at WhateverGreen patches.

EDIT: same case for thunderbolt peripherals.
