[solved] [HELP] Still no solution for HD 620

[gongzhen]

Another whole day playing with the painful graphics, ended up with a glitch or broken acceleration. Then I decided to ask for some help here.
The laptop (or tablet) has a 12' screen with 2800*1920, which makes HiDPi the most urgent problem to deal with.
Also, the Phoenix BIOS is encrypted and setup_var or modification under linux method doesn't work to adjust DVMT-Prealloc.

Installed with 0x12345678, then tried to get the acceleration to work.

Upon boot up I installed some kext and rebuilt kextcache. Straight restore to 0x19160000 cause KP. Then I tried with FakePCIID installed along with 0x19160000 and the boot process stuck at those [IGPU] entries.

After a few searching, I tried SSDT-IGPU.aml and AddDevice in Clover, both left me a glitch login screen even with the glitch patch on.

The "Problem Reporting" files is generated with 0x12345678 and NoDefaultProperties manual selected, resulting the acceleration broken.

A bit disappointed or despaired... My previous hackintosh has so many difference with this one, I have to fix audio, battery, sleep, thunderbolt, usb type-c port, I2c trackpad (emulated as mouse with VoodooPS2), I2C Wacom touchscreen... too many works and a lot stuffs I haven't deal with before.

See guide:

It has instructions for dealing with 32mb DVMT-prealloc.

Thanks for your help.
I think I have found the problem. After I removed IntelGraphicsDVMTFixup.kext and use KextToPatch to patch fb, the screen finally boot up with 1536 MB graphics, screen size recognized and HiDPi enabled. Then I rebuilt kernel cache again and this time the acceleration works.
Maybe the kext have something contradict with KextToPatch, or just conceal me. So, keep it simple and get everything fixed step by step.

Your copy of IntelGraphicsDVMTFixup.kext is probably not working (some versions that were released simply didn't work). Or you forgot Lilu.kext. Or you didn't have a correctly matched set Lilu.kext + IntelGraphicsDVMTFixup.kext.

Marked solved.
