No QE/CI on Intel HD4000 under 10.10.4

Hi guys, 

 

I've just faced with a strange problem of lacking QE/CI acceleration on a fresh 10.10.4 install on my Samsung NP900x3c, i7 ivy, HD4000, 1920x1080, ALC269VC, no dsdt patches, Clover 3259 bootloader. The thing is that with the same Clover config I can boot 10.9 and have full acceleration while 10.10 is booting but no QE/CI. Another thing is that 10.9 provides desktop and QE/CI only with the following ig-platform-id:  0x01660002 0x01660008 and 0x01660009, other ig-platform-id prevents 10.9 from booting, while 10.10 provides fully functional desktop with any ig-platform-id but no QE/CI at all

I attached clover config, darwindump and ioreg of 10.10 Any help would be very much appreciated :)

 

Thank you, Dmitry

so, most likely you should use 0x01660003 or 0x01660004. along with mbp9,2 smbios and inject intel. with dual link patch too.

 

dsdt edit recommended to fix the gfx0 for igpu, for the agpm load properly.

 

this method works in all versions and never changes. if your graphics where really working in one system, it should work in any other since then. intel hd4k activates the same way since supported by osx.

@mendietinha, I've tried these ig-platform-id: 0x01660002, 0x01660003 and 0x01660004 with a clover config based on rehabman's https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD4000_1366x768.plist with only little fixes and patches in it to make the system boot without patching dsdt.aml I tried with and without dual link patch, with and without MacBookPro9,2 No success. I have neither transparent menus nor screensaver preview. Meanwhile, with the same rehabman's config with  ig-platform-id 0x01660002 I can have QE/CI on my 10.9. The only difference is that 10.9 is started from SSD while 10.10 from an external usb drive. But I don't think it might be a reason of this graphic acceleration problem.

​Just in case, I attached the config file I used.

Something's really goes wrong with QE/CI on HD 4000 under 10.10.4

​Any help would be very vouch appreciated.

Regards, Dmitry
