[87zrjojo]

where's the KabyLake minStolenSize patch such 0x591b0000?

where's the KabyLake minStolenSize patch such 0x591b0000?

It is not difficult to derive from the information in post #1, but see plists linked by the laptop guide:

hi, I put the question here, can someone help me?
I checked the link https://www.tonymacx86.com/threads/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3.162062/, it said people can check the current DVMT pre-allocated memory size, balabala...

If Dedicated Video Memory = 0MB, then DVMT pre-allocated memory in BIOS settings is 32MB.
If Dedicated Video Memory = 32MB, then DVMT pre-allocated memory in BIOS settings is 64MB.
If Dedicated Video Memory = 64MB, then DVMT pre-allocated memory in BIOS settings is 96MB.
If Dedicated Video Memory = 128MB, then DVMT pre-allocated memory in BIOS settings is 128MB.

ok, I checked my laptop, and confirmed my DVMT pre-allocated memory in BIOS settings is 128MB as per the last item listed in above.

and, my loaded kext is AppleIntelKBLGraphicsFramebuffer.kext, the code showed in Hex Fiend is (ig-platform-id: 0x591b0000):
01030303 00006002 00005001

question:
only when I put IntelGraphicsDVMTFixup.kext into /S/L/E or using 32M(19M+9M) DVMT pre-allocated patching in Clover/KernelAndKextPatches/KextsToPatch
then I can boot my hackintosh smoothly.
when I don't use IntelGraphicsDVMTFixup.kext or KextsToPatch, then the reboot happens again and again.

so, what should I do, using IntelGraphicsDVMTFixup.kext or KextsToPatch, I get the DVMT pre-allocated memory only 32M, but my BIOS setting is 128M.

You forgot to read the FAQ:

IMPORTANT!: Contrary to many of the guides you will read, Windows is NOT a valid way to determine what DVMT-prealloc is set to. There is no correlation, especially with Windows 10.

thanks RehabMan, it clear now.

but I wanna to say that I haven't seen a successfully patching by setting 64M or 128M DVMT-prealloc till now, can someone teach me a example? my loaded kext is AppleIntelKBLGraphicsFramebuffer.kext, the code showed in Hex Fiend is (ig-platform-id: 0x591b0000):
01030303 00006002 00005001

The guide plists already have a 32mb DVMT-prealloc patch for KBL:

Deleted. nvm. Misread FAQ

et's take a look at the framebuffer data for a commonly used ig-platform-id on Broadwell, 0x16260006:

06002616 01030303 00002002 00005001

how do you get this number? using xcode?

how do you get this number? using xcode?

Looking at the framebuffer kext binary in a hex editor (I use Hex Fiend).

what is the suitable kext for high sierra intelhd620 kabylake? is it AppleIntelKBLGraphics ? it looks like it is missing in my sle can i get it somewhere?
