AMD Radeon Navi GPU

[simon-lsp]

I have now built a Kext based on Brumbaer's property injector which does the job for Radeon VII, RX 5700, RX 5700 XT, Vega 56, Vega 64 and RX580. All it does is injecting the framebuffer properties of the Apple counterparts of the mentioned PC graphics cards.
If you want additional properties or a PowerPlay Table you can either edit the kexts info.plist to your likings or just use Clover / OpenCore property injection for that.
Should work with Hackintoshes, real Mac Pros and eGPUs. Feel free to test and report your results - especially Geekbench results.

Thank you, CMMChris, I used OpenCore property injection for that. Cannot boot, my graphics card is RX 580

I am reading through this thread and trying to decide what to do. I have a z390 Designare, 9700k and Sapphire Pulse RX580 8Gb - right now I am using headless platform ID and Lilu/WEG and iMac Pro 1,1 with IGPU activated. What should I do and what are the exact steps to take. I am trying to learn, but I also don't wanna screw up.

Its for new Navi video cards.

For RX 5500XT, RX 5700XT/5600XT, RX Vega 64.

@mattystonnie, do you have one for RX 580? I couldn't figure out how to get my LG 4K TV working from HDMI port in addition to two LG 4K monitors connected to the DisplayPorts on my Sapphire RX 580 card. I wonder if this will work.

Use a hdmi 2.0 cable that supports 4k.

Use a hdmi 2.0 cable that supports 4k.

Not sure if the cable is HDMI 2.0 certified, but it works on Windows 10. On Catalina, the TV is detected but the TV is black and says No signal is detected. I also tried using another HDMI cable, same result.

Found other way to inject the discrete gpu.

In clover config file under devices -> properties, no need for WEG or Clover inject ATI.

The big performance difference was when I inject the EFI GPU driver, without it the Geekbench score was low on pair with WEG around 90000...

@mattystonnie, what values should I use for RX 580, want to try it on OpenCore 0.5.7.

Using WEG add boot ards -cdfon

The SSDT method works with my setup which consists of an Asus Prime Z370 A ii, 9600k stock clock, XFX RX 5700, and Headless iGPU on the SMBios iMac19,1. Weg is active with ShikiGVA=80 and agdpmod=pikera.
Note: I'm using DisplayPort, not HDMI, the connector furthest from the motherboard. I just tried a film in Apple TV+, and Netflix in Safari and DRM works. @slim.jim you might find that interesting.

My Netflix issue was a browser issue. I cleared all site data for Netflix and now DRM is working fine for me with WEG and no shikigva boot arg.
