Guide How to Patch AMD Framebuffers for High Sierra using Clover

[junecaz]

Does your system work without injectATI=true and using the RadeonFramebuffer? If so why are you experimenting? Your patch looks ok from just a glance. What framebuffer are you trying to patch?

Hey carpentryplus25, thank you for the help!

Yes, works fine. With (I tried Ramen or Tako) or without injectATI, but some times without injectATI I got black screen when wakeup the computer.

Do you know why in the radeon_bios_decode and redsock_bios_decode dump I have only 3x DP if my GPU has 4x physical DP?

Non reference design 7970 will likely require using the Radeon Framebuffer instead of using patched injected framebuffer mainly since your card has more ports than the framebuffers in the Kext if my memory serves me correctly you can only use four of all the ports anyhow so you can try patching Namako framebuffer with your desired ports or use Radeon Framebuffer with RadeonDeInit=true and clover version 4296+ To resolve the black screen issue if you have a UEFI vBIOS on that card and I believe it does

Your injectATI=true with FBName=Baladi isn't working suggest renaming PEGP to GFX0 in ACPI tables add this to your config.plist in ACPI patches section

Find:
50454750

Replace:
47465830

I added that, rebooted and rebuilt the cache but it made no odds

Well I think you may be out of luck there... I searched a lot and didn't find a single user with 290x reported to have more than two displays working...Maybe HDMI connection is working alongside the DVI's...

Alright mate Cheers for your help

I wouldn’t give up try the other Framebuffer in the 8000 kext

If anyone with sapphire r9 290x 4gb wants to test multiscreen with Baladi framebuffer patch in High Sierra, DVI's + HDMI should work, I guess with display port and bigger resolutions we're out of luck or we just need to experiment a lot to get it right...

hi，friend
I'm from China.My domestic hackintosh BBS has been hung up, I have to look at some foreign BBS, looking for a successful case of SVE151. The bad thing is that my English is very bad, and I need to use the translation tools. And I don't know why. My computer can't extract the files used in the tutorial. I'm looking forward to your sharing of graphics cards. If you can, can you share your elf files?

In fact, I have been paying attention to you for a long time at BBS, your loyal friend. Look forward to what you can do more perfectly. I also look forward to your help.

Yes very common on all AMD graphics card using AMDLegacySupport.Kext since 10.12.4 so pretty much all 6000 series and earlier use SwitchResX.app to correct the issues change from billions of colors to millions of colors. I have the same issue with my AMD HD 5870 Apple branded graphics card. Reddish/Blueish flickering type behavior.
