Unable to get HD630 work on XPS 15 2-in-1

[shiecldk]

My laptop specs are:
XPS 15 9575
4K Display (3840*2160)
i7-8705G Processor with Radeon™ RX Vega M GL graphics
HD630 (device id and vendor id: 0x591b8086)
Windows 10 + First installation of macOS (10.13.4) on APFS in the same disk

 

It cannot boot into desktop with KBL framebuffers, such as 591b0000, 59160000, and 5912000, injected by Clover. The system reboots immediately right before getting into desktop.

 

I have been modified the DVMT Pre-Allocated from the default 64mb to 128mb (technically, see the dumped code below).

RIght now, I can only get into desktop with 0x12345678 framebuffer and fakeid right now, which doesn't drive the HD630 (no QE/CI).

DVMT dumped from bios:

You got a discrete card, try spoofing it with this SSDT to /EFI/Clover/ACPI/Patched and enable "AutoMerge" in Config file. Also try adding IntelGraphicsDVMTFixup.kext to Clover kext

 

SSDT-discreteSpoof.aml

IntelGraphicsDVMTFixup.kext.zip

Thanks for the help.

I've tried both files. However, both don't work.

With the SSDT-discreteSpoof.aml alone, the system still reboots immediately before getting into desktop.

WIth IntelGraphicsDVMTFixup.kext or both installed, the system stuck at the line

"IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0"

 

The attachment is my ACPI files. Could you see how I could make changes to the discrete card disabling ssdt?

 

Thank you!

try these

Hi, I tried the files.

Here is the KP messages:

 

[Jake Lo]

looks like you have VoodooI2C kext install?

Can you remove it temporarily?

[shiecldk]

I get this KP message instead (same as what I initially got)

 

However, if I use the if-platform-I’d, 0x59120000, I can get into desktop without KP but the screen is black.(judged by keyboard cap light and disk reading light)

All other KBL ig-platform-id give me KP.

 

I wonder if I can fix the black screen problem by patching connector-type of 0x59120000

 

[shiecldk]

I get into desktop with invalid 0x12340000 ig-platform-id to check dGPU.

It seems dGPU is not disabled with the dsdt you provided.

 

IOREG is attached:

 

ioreg.ioreg

Try this DSDT

DSDT.aml

Awesome! Thank you Jack.

AMD card is disabled. I checked with 0x12345678 ig-platform-id.

No luck with Intel hd630 tho. My guess that problem is about the naming of GFX0 and IGPU.
