I'm on OpenCore, trying to GPU SPOOF my R9-290.
Problem is, most of the tutorial don't have PCI-Bridge between the ACPI path to the GPU.
My motherboard is Z97-WS, which have a PLX PCI-Bridge in the motherboard.
From Windows Device Manager it looks like this:
ACPI(SB)#ACPI(PCI0)#ACPI(PEG0)#ACPI(PEGP)#PCI(1000)#PCI(0000)
Converts to:
_SB_.PCI0.PEG0.PEGP

When I specify _SB_.PCI0.PEG0.PEGP for device-id, it only change the PEGP itself.
It does not inherited to PCI-Bridge@10 and display0(GFX0 if enable WhateverGreen).

device-id and model are set in PEGP.

The GFX0 (display@0) remain unchanged.


Also, I tried to edit config.plist > DeviceProperties with PCI Path found in hacktool.
It looks like this:

Still no changes.

Is there anyway to fix this kind of problems?
I attached my config.plist, my current SSDT and IOReg!
Thanks For Helping:lol:
