Inject FB Name For AMD Radeon RX Vega 64

[shathenine]

with this ssdt edits, would it be possible to run Display port 4k screen and HDMI HD screen without whatevergreen or vegafixup kexts?

I have problem with these kexts FCPX export to h264 breaks, but i need to run both of my screens for work...

If you need to run both of your display monitor，you have to use vegafixup，this is a bug in macOS 10.13.4 and macOS 10.13.5 Beta.

one screen would run with this edit but without these kexts? I need DP 4k screen at least

I only use the AppleGraphicsDevicePolicy Patch, all my ports work however I do not use FCPX I also have a Vega56 not a 580 like you. All crashes stoped when I deleted whatever and lilu

can you please point me to the patch you mentioned? For Vega like you, as i have upgraded gpu

 

[scottkendall]

it is a kernel patch in clover Under Kernel and Kext Patches, I have the below. However, I downloaded someones EFI who had to the same board when I built my hack and this patch was part of the file. I can not tell you much other then when I use this all my ports work and crashes stop. I have since added Lilu back and the crashes have continued to remain not existent.

Hi all. My Vega 56 crashes in games. I am not using any extra kexts and my card shows the proper name in system info. My OS is the latest High Sierra. Is there a method specific to Vega 56 to stop the crashing?
