[solved] DVMT patching for a skylake system

[AM0207xx]

Patches depend on the ig-platform-id in use.
Use a hex editor to look at the data for your ig-platform-id in the AppleIntelSKLGraphicsFramebuffer binary.
The connector definitions start with 0105 and 0204 and are 12 bytes long.

For example, 0x19160000 you find (search for 00 00 16 19) for port 0105:
01 05 09 00 00 04 00 00 87 01 00 00

patched for (12) and HDMI audio:
01 05 12 00 00 08 00 00 87 01 00 00

I insert the code in my config.plist, but the connector type is still "04" and not "08".
I attached "Problem Reporting" files.

PS: Can you say me where the AppleIntelSKLGraphicsFramebuffer is located, because I downloaded hex fiend and want to find it out for myself.

Your Find pattern is wrong and not according to what I wrote in post #190.

The binary is at /System/Library/Extensions/AppleIntelSKLGraphicsFrambuffer.kext/Contents/MacOS/AppleIntelSKLGraphicsFramebuffer

I change the "Find" code, but still the @1 connector type is "04".

I made some research and when I want to patch it for @2 should I insert:

Find: 02 04 0A 00 00 04 00 00 87 01 00 00
Replace: 02 04 0A 00 00 08 00 00 87 01 00 00

I attached my config.plist and a copy of IOREG.

Your patch is incorrect.
You're trying to patch AppleIntelBDWGraphicsFramebuffer.
Your system is using AppleIntelSKLGraphicsFramebuffer.

AppleIntelBDWGraphicsFramebuffer is for Broadwell. Your system is Skylake.

Also, you have a lot of nonsense patches for AppleIntelSKLGraphicsFramebuffer.

AppleIntelBDWGraphicsFramebuffer is for Broadwell. Your system is Skylake.

Also, you have a lot of nonsense patches for AppleIntelSKLGraphicsFramebuffer.

But I searched in the binary of AppleIntelSKLGraphicsFrambuffer.kext.
I attached a photo of Hex Fiend where the AppleIntelSKLGraphicsFramebuffer is opened.
I also removed the nonsense patches in my config.plist.
But the patch for AppleIntelFramebuffer@1 still does´t work, the connector type is still patched for DP and not for HDMI.

Look at your config.plist carefully.
You entered the patch for Name=AppleIntelBDWGraphicsFramebuffer.

 

[AM0207xx]

Look at your config.plist carefully.
You entered the patch for Name=AppleIntelBDWGraphicsFramebuffer.

Thank you, RehabMan.
I really don´t know why the name was wrong in my config.plist.
Now the connector type of AppleIntelFramebuffer@1 changed to "08".
In post #188 you wrote that I need to patch both, @1 and @2.
The patch in #194 I extracted from the binary of AppleIntelSKLGraphicsFramebuffer, is it right?
I searched in Hex Fiend for "0204" and for "00 00 16 19" like you wrote in post #190.

Try it and see if you see the result of the patch in ioreg.

My patch does´t work...
I opened AppleIntelSKLGraphicsFramebuffer and searched for my ig-plattform id ( 00 00 16 19 ).
Than I found the code for port 0105: 01050900 00040000 87010000
and the code for 0204: 02040A00 00040000 87010000

I insert in "Replace" 02040A00 00080000 87010000 to change the connector type from "04" to "08", but it does´t work.
Maybe you can give me a hint what I should insert to get it working.
