HD4000 full acceleration for 10.8 / 10.7.5

[liyuankunbix]

I enabled VGA port on a GA-Z77X-UP5 TH editing AppleIntelFramebufferCapri binary to change the port.

 

I use AAPL,ig-platform-id: 01660003, injected via DSDT.

and edited AppleIntelFramebufferCapri binary at framebuffer @3 from this:

 

@0, 05 03 00 00 02 00 00 00 30 00 00 00 // (LVDS)

@1, 02 05 00 00 00 04 00 00 07 04 00 00 // (DisplayPort)

@2, 03 04 00 00 00 04 00 00 81 00 00 00 // (DisplayPort)

@3, 04 06 00 00 00 04 00 00 81 00 00 00 // (DisplayPort) - DETECTED 0x0 desktop

 

to this:

 

@0, 05 03 00 00 02 00 00 00 30 00 00 00 // (LVDS)

@1, 02 05 00 00 00 04 00 00 07 04 00 00 // (DisplayPort)

@2, 03 04 00 00 00 04 00 00 81 00 00 00 // (DisplayPort)

@3, 06 02 00 00 02 00 00 00 30 00 00 00 // (DisplayPort) - Working VGA - Version 1

 

this worked too:

 

@0, 05 03 00 00 02 00 00 00 30 00 00 00 // (LVDS)

@1, 02 05 00 00 00 04 00 00 07 04 00 00 // (DisplayPort)

@2, 03 04 00 00 00 04 00 00 81 00 00 00 // (DisplayPort)

@3, 06 02 00 00 01 00 00 00 30 00 00 00 // (DisplayPort) - Working VGA - Version 2

 

Chameleon SVN 2.1 r2064, GraphicsEnabler=No and GraphicsMode to match monitor resolution, Mountain Lion always detected the HD 4000, but without QE/CI.

Injecting platform Id get QE/CI enabled, and editing AppleIntelFramebufferCapri get video through VGA (i´ve only have a VGA monitor)

 

Thank you ，ac3bn，thank you very much . Now my HD4000 works perfectly with OS X 10.11.5 and a VGA monitor.
