[Guide] Intel Framebuffer patching using WhateverGreen

[emveepee]

Ok thanks to WhateverGreen Lilu and FBPatcher I know have a working accelerated UHD 630 running on B360 Coffee Lake with 2 HDMI and 1 VGA monitor running together on Mojave including HDMI audio and Realtek AC662 audio, and sleep works too. The only issue I still am having is I don't get a selection for 4k @ 30. I do get 4k @ 30 when the machine is not running with framebuffer so it might be possible. Does anyone have a suggestion on to make those options appear in the Display Options?

The only combination that has got this work for me is 18,1 device-id 0x3E920009 with this (note I am not sure where FB Patcher is finding 3E9B0007 for the ID I don't get the connections showing for it. Is it possibly a question of flags?

If you need further info let me know

Try to set Patch->Advanced->Enable HDMI20 (4K) and then export your patch again.

Intel FB-Patcher displays your current Platform Id under General->System Info->Platform Id. Are you saying it's detecting it incorrectly?

It is there already and shows in ioreg

If I select the real ID I don't get the proper connection view.

You can select Preferences->Displays and hold down Alt key while clicking Scaled to get extended display modes. I personally use SwitchResX but it costs money.

Yes that's correct. If you want to see your applied patches select Patch->Apply Current Patches.

I tried both of those already, I see a lot more in the Option Click and SwitchResX does give me 1440p but I don't get 2160p that I get with the framebuffer off.

Thanks I will play with that. FBPatcher worked great for disabling USB ports. One note on Audio I had to run FB Patcher in High Sierra to get the device-id because I couldn't get any PCI audio at all using just the injection.

I don't know I have a desktop and laptop both running 4k (HiDPI mode) and haven't had any problems. One thing I can suggest is to do a kext flush (run "sudo kextcache -i /" from Terminal) and a few reboots. It sometimes takes a few times before it kicks in for me.

Hopefully that was only due to running an older version of FB-Patcher. It now tries HDAS if HDEF fails so should hopefully detect the audio hardware correctly before patching.

I do see other HiDPI entries just not the high ones. I will try the flush.

It is not really FB Patcher related, Mojave would not expose any audio devices on the PCI device for you to read with the Inject 5 that I used.

Once headkaze made me realize that
10.11-SKL-1912000-4_displays with IntelGraphicsFixup is simply with WEG

framebuffer-patch-enable  Data  <01000000>
framebuffer-portcount     Data  <04000000>

WEG works fantastic to fix the black screen on boot with my Core i3 6300 iMac17,1. I was even able to boot the Mojave installer with full resolution and graphics acceleration.

I also changed to HDMI and DVI connector types to match the physical connectors.

I am now trying to implement HDMI audio. The Intel Framebuffer patching instructions specifically mention to remove any HDMI and IGPU entries from config.plist/Devices/AddProperties.

With IntelGraphicsFixup, I had the following entries below for HDMI audio. So, how do I replace those entries for WEG?

Move any such properties such that they are injected with config.plist/Devices/Properties instead.

If you're using Lilu + AppleALC you can use Intel FB-Patcher to patch your audio (General->Audio tab). Then set your Layout Id to 13 in the drop down list and put a tick next to Patch->General->Audio.
