Spoof PCI device ID in Windows

[zack4485]

Can anyone help me change the PCI device ID on a GPU in Windows? I've implemented an OpenCore config.plist deviceproperties rename and that doesn't work. I've created an SSDT to rename the device and that doesn't work. I've combined the SSDT with an OpenCore patch to rename the device's _DSM method and that doesn't work.

See attached my config.plist and my SSDT file...

So, you need to spoof a device ID on Windows? Or is it on macOS?

I want to spoof on Windows using OpenCore and/or SSDT...I don't see why it shouldn't be possible when SSDTs are seen by all operating systems (unless you explicitly add an "if" condition to filter out certain OS).

It's definitely possible to spoof a PCI device ID in Windows because that's how the NVIDIA vGPU unlock works on Linux--you have to tell KVM to present a consumer-grade GPU device ID to Windows.

I'm just trying to do it in OpenCore and/or SSDT instead of having to run a KVM-based VM.

At least for now my assumption is my SSDT or my OpenCore patch is wrong and could be troubleshot as if it's MacOS--I don't see any reason (yet) to think the problem is with Windows.

Can somebody take a look at my patch and my SSDT and tell me if there's any obvious errors?
