applehacker Posted September 11, 2014 Share Posted September 11, 2014 Guys, I've finally managed to do it. Two years (on/off) worth of testing, and I've finally managed to enable FULL dGPU ACCELERATION in OS X Mavericks for the ATi Mobility Radeon 7970M HD!!! I have something useful to contribute finally Proof: http://i57.tinypic.com/2r60jzs.png I found/decoded the correct connectors and patched the appropriate controller kext, and it works beautifully. So far, on the M17x R4, the following is working {Note: I am using Chameleon Bootloader r2380} Full CPU Support (all cores/threads) [native support] All RAM Recognized (in my case, 16GB) [native support] Intel HD 4000 Full Accleration (when set to iGPU or SG in BIOS) [patched in the DSDT] ATi Mobility Radeon 7970M Full Acceleration (When set to PEG in BIOS) [needs my patched kext] DVD/Blu ray drive (works natively) Touchpad mimicking Apple's Touchpad (works with VoodooPS2) All USB/ESATA Ports (works with correct DSDT) Webcam (works with correct DSDT) Wifi (replaced stock card with AR9280 card, recognized natively) Bluetooth (works natively) Things still need to be worked on: Audio (the flaky Recon3Di chip is not helping my case....) [probably will approach with voodooHDA, later with AppleHDA] Sleep/Wake support [needs DSDT tweaking] WORKING HDMI Output [needs connector patching in framebuffer] DP Output [needs connector patching in framebuffer] VGA Output [needs connector patching in framebuffer] AlienFX Control [no freaking clue.....] Memory card reader [will explore voodooSDXC] Additional cards may be made to work if they are donated to me to work on (talking about ATi cards, I refuse to work on nVidia) So all in all.....ITS POSSIBLE GUYS! Link to my "Extra" folder, including patched AMD kext: http://www.mediafire.com/download/vd037sda5anouur/M17x_R4_Extra.zip For those interested: Proper Framebuffer is: Buri Initial address in framebuffer: 02000000000100002905010010000505 the proper connector patch is: 02000000400000000901000010000005 M17x_R4 Extra.zip AMD7000Controller.kext.zip Link to comment Share on other sites More sharing options...
vusun123 Posted September 11, 2014 Share Posted September 11, 2014 You only patch the LVDS ? Link to comment Share on other sites More sharing options...
applehacker Posted September 11, 2014 Author Share Posted September 11, 2014 For now yes. HDMI output is expected to be working as well, it was working natively with Buri framebuffer so I didn't bother to edit/change it. No VGA to test and no display port to test either.

Rikoshet Posted September 12, 2014 Share Posted September 12, 2014 Success here! Thanks Lawrence! I was using Clover injection and always have color issue. Now I'm injecting like you via DSDT (copy/paste your) and now it works! Just thinking about I've loosed a couple of months to undestand the problem... Cinebench score 59.82! How about your? Find some info? Thanks again! Link to comment Share on other sites More sharing options...
