Hey Hack Gurus,
Hoping someone who is better with ACPI than i am can help me out with this. Normally, I have not had trouble adapting the various SSDTs to the various motherboards/systems that I run. But, I have spent a few hours trying to get this one to work to no avail.
I grabbed the Radeon VII SSDT from KGPs repo and successfully adapted it to my Z390 systems. I also successfully adapted it to my X299 system at first. But, once i installed another PCIe card into the last slot, it seems to have triggered an additional bifurcation of the PCI bus, and I can't seem to get the SSDT to load properly at the new address for the GPU.
When the GPU was by itself in the first slot, it was showing up on PC02->BR2A...
After installing a Blackmagic deckling in the last PCIe slot, the GPU now is showing up on PC02->BR2C...
And I /think/ there is another pic-bridge in the path which might be my issue since I am not sure how to deal with that.
Can anyone help me adapt the SSDT to this new ACPI address? I am attaching my original working (when the decklink card is not installed) as well as screenshots of the IORegistry showing the new paths.
Much appreciated!

EDIT: Nevermind. Of course, right after posting this, I finally got it working. What was throwing me off is the first time, I did a reboot after (apparently) properly adapting the SSDT. The boot would actually hang with a timeout on GFX0. I thought this meant my SSDT was broken, but after one more reboot, it's actually working fine. So, I have no idea what that was about.
