Question - what to do if the paths are the same?

Hi,

Thanks a lot for this tutorial!

Both my gfxutil and IODevice tree paths match and are the following:
/PC00@0/PEG1@1/PEGP@0/pci-bridge@0/GFX0@0

So, using your example, lines 12 and 14 appear as follows:

`External (_SB_.PC00.PEG1.PEGP, DeviceObj)`

`Scope (\_SB.PC00.PEG1.PEGP)`

Then I tried to replace "BRG0" with "pci-bridge", but MaciASL returned an error and would not allow me to save that.

So, here are my questions:

  1. When the paths match, do I need to create the SSDT aml?
  2. If so, should I be replacing BRG0 with something else, since "pci-bridge" does not work?
  3. Also, should I be replacing BRG0 on both lines 10 and 20?

Hello,

  1. Yes, if the GPU doesn't show up, you need the aml. Since the paths match, you can use it how it is without modifying it.
    2 and 3. No, keep it BRG0

The monitor shows up when I go to "About this Mac" (see screenshot), and that is new since updating the config according to your directions. Before that, it wasn't listed.

The thing I still notice is that under System Settings --> Displays, it says "Unknown Display" (see screenshot) and there is only one resolution (2560 x 1440).

Is the "Unknown Display" a GPU issue or monitor issue? Or, maybe a whatevergreen.kext issue?

Im not too sure, but it sounds like more of a mac os issue. I would test if you have GPU acceleration, that would tell you if your GPU is working

I was able to get this working. My GPU is a 6600 XT. So, I had to use a different device ID. FF730000 was the one that worked for me. I found it on a website that has all the AMD GPU device IDs. Thanks for your input. I couldn't have gotten it going without your instructions here.

Np, glad it's working for you
