Catalina 10.15.7 - Radeon VII only working on one DP output

[Mo Facta]

Hi, 

Upgraded from Mojave to Catalina 10.15.7.  Thanks to MaLd0n for his excellent work.  

However everything is working great except for the Radeon VII's outputs.  Only one Displayport works but the HDMI and other DPs output this garbage:



Any ideas?  I can't seem to find a solution.

Thanks in advance. 

Cheers

Yes, I updated the ones that Clover Configurator said were out of date.  Lilu and WEG and AppleALC.  That was it.  Clover is 5137, one below current, which I didn't update yet.  Trying Big Sur now with a RX 6800.  

Have you seen this before?  I've been building hacks since Leopard and this is a new one.  The Radeon VII worked perfectly natively in Mojave but refuses to give all 4 outputs properly on both Catalina and Big Sur.  I confirmed earlier on today that Big Sur had the same problem. 

I know the card and its physical outputs are fine because I can get video for the BIOS and Clover bootloader on all of them including the apple loading screen.  As soon as the OS lanches it goes into that garbage in the pic I posted except for the first DP port.  

I'm installing Big Sur now with your EFI and an RX 6800 and so far it's installing fine.  Will see how the outputs react when I'm in the OS.    

Any suggestions in case I need to roll back would be a great help @MaLd0n.  Thanks as always for your amazing support.

Cheers

@MaLd0n Big Sur installed no problem and all GPU outputs work fine now. 

However I'm having USB mapping problems now.  Only 3.1 ports work now and the rest of the USB 3 ports don't recognise USB3 devices.  Can you help?

Solved.

Used Hackintool to create USBPorts.kext.  

Everying working 100% now. 

Radeon VII is obviously not working properly on 10.15.7.  

Cheers
