this is kinda my macos hack - works for some displays but i dont like it

this is ida pro bad dissasemble

I replaced it with your recently modified NootedBlue and did some testing again.
The result is as follows, with some changes :

1. -v keepsyms=1 debug=0x100 -igfxcdc -allow3d

1-1. GraphicsSchedulerSelect = 0 (Default, not modified NBlue Info.plist)
IOKit Daemon (kernelmanagerd) stall[0], (60s): 'IGPU' (a,24020002) log infinite output.

1-2. GraphicsSchedulerSelect = 2
IOKit Daemon (kernelmanagerd) stall[0], (60s): 'IGPU' (a,24020002) log infinite output.

2. -v keepsyms=1 debug=0x100 -igfxcdc -allow3d igfxfw=2

2-1. GraphicsSchedulerSelect = 0 (Default, unmodified NBlue's Info.plist)
It boots, but logs show firmware load failure and graphics acceleration does not work.
Same as IGPU log in Test6 result above.

2-2. GraphicSchedulerSelect = 2
During booting, AuxKC loading is completed and IGPU log output stops.
I think it caused an "Unsupported GraphicsSchedulerSelect=2 kernel panic".
Forced restart shortcut (Ctrl + Command + Power Button) does not work.

2-3. GraphicSchedulerSelect = 5
IOKit Daemon (kernelmanagerd) stall[0], (60s): 'IGPU' (a,24020002) log infinite output.

Unexpected context status buffer entry kernel panic does not occur, and instead the log below continues to be output infinitely.

IOKit Daemon (kernelmanagerd) stall[0], (60s): 'IGPU' (a,24020002)

i tried nootedblue on my laptop, same results as you all get. im booting into windows until we get a working kext somehow.

jalavoui · March 22

can you guys try use whatevergreen and figure out what parameters are set in framebuffer to make it work ?

the HwRegsNeedUpdate from whatevergreen didint work for me that's why i made a patch

GraphicsSchedulerSelect controls the firmware loading dont use with igfxfw...

Mastachief · March 22

By using the modified whatever green from shl628,

the below settings below allow booting to a black screen. you can remote to the machine, the session has the framebuffer working, those images that you see posted near the beginning of this thread are proof.

important note, if you change the framebuffer-con1 to framebuffer-con0 in the Device properties while using the below config, you get a KP, however if you change it to con2, con3, there is no change in ioreg, it always attaches to appledisplay on framebuffer@1 the specific property however should be applebacklightdisplay on frambebuffer@0 which doesnt happen.

this is code from whatevergeen (i guess debug version)

#ifdef DEBUG

if (callbackIGFX->dumpFramebufferToDisk) {

char name[64];

snprintf(name, sizeof(name), "/var/log/AppleIntelFramebuffer_%d_%d.%d", cpuGeneration, getKernelVersion(), getKernelMinorVersion());

FileIO::writeBufferToFile(name, callbackIGFX->framebufferStart, callbackIGFX->framebufferSize);

SYSLOG("igfx", "dumping framebuffer information to %s", name);

uint32_t delay = 20000;

PE_parse_boot_argn("igfxdumpdelay", &delay, sizeof(delay));

IOSleep(delay);

}

#endif

can you post it after you boot the system ?

Attach the dump file created after booting by applying -v keepsyms=1 debug=0x100 -wegdbg -igfxcdc -igfxdump boot args.

i haven't figure out howto proper setup the device properties (much easier on amd cards) but i changed default ig-plat and dev-id and it hangs without crashing

the ig platf/devid combo just loads some incompatible registers?

i set default bios to 4. if you guys wanna try other ig platf/devid do it in code or using opencore (need -allow3d enabled)

this is my current OC hacks

enabling IMEI with or without a fake id will hang the driver. turning off will panic

benmacfreak · March 25

well all, i got ventura installed, i tried the fork of nootedblue, and weg, several different deviceproperties etc. about this mac ONLY shows intel iris xe graphics 7mb, and no framebuffer loaded, no metal/opengl, nothing. Im unsure why, im not booting with -igfxvesa, im literally stumped on how to fix this, i read the whatevergreen faq many times over, etc. i cant find a working display properties setting, any help or advice please let me know. Thanks.

Can we redirect the incompatible registers via offsets?

jalavoui · March 25

benmacfreak, dont use whatevergreen with nblue...

the incompatible registers can be changed. but see this sample code:

#define SOFT_SCRATCH(n) _MMIO(0xc180 + (n) * 4)

#define SOFT_SCRATCH_COUNT 16

#define GEN11_SOFT_SCRATCH(n) _MMIO(0x190240 + (n) * 4)

#define GEN11_SOFT_SCRATCH(n) _MMIO(0x190240 + (n) * 4)

#define MEDIA_SOFT_SCRATCH(n) _MMIO(0x190310 + (n) * 4)

this exists in IGHardwareGuC::loadGuCBinary

in ida this is the code

  v7 = this[7];
  v8 = (_DWORD *)*((_QWORD *)v7 + 590);
  v8[1633] = 1;
  v8[319579] = 1;
  v8[9481] = 16;

this might work

from https://github.com/lvs1974/IntelGraphicsFixup/releases

uint32_t IGFX::mmioRead(void *fw, uint32_t reg) {

auto fIntelAccelerator = getMember<void *>(fw, 0x10);

auto mmio = getMember<volatile uint32_t *>(fIntelAccelerator, 0x1090);

return mmio[reg/4];

}

void IGFX::mmioWrite(void *fw, uint32_t reg, uint32_t v) {

auto fIntelAccelerator = getMember<void *>(fw, 0x10);

auto mmio = getMember<volatile uint32_t *>(fIntelAccelerator, 0x1090);

mmio[reg/4] = v;

}

right i wouldnt know how to patch it either, as i have NO coding experience or IDA experience at all, i did look at some videos, and other stuff. I'm tbh lost, and wouldnt know how to do it unless i was to (no lie) have someone on remote helping me..

nor am i knowledgable enough with hackintosh to do it for myself whatsoever.

wifi finally working for Intel(R) Wi-Fi 6 AX101 0xA0F0 id 0x0244 in ventura

patched from github version

install the Airport kext in OC

the itlwm kext also works but will need some addon to scan networks

for BT i'm using shl628 files

updating the os hangs the driver - so just disable nblue if updating

done with ventura latest 13.6.6

i am still stumped guys, i havent gotten the patch from yesterday going yet, i'm on Arch Linux for rn till someone can help me..

jalavoui · March 27

idk if this happens with others using tiger lake mobos but

applealc makes kernel_task usage fires to 70% (normal is 2%) while doing nothing

nblue is causing displaypolicyd crashes + windowserver usage bump cause of timmings patch

i'm rechecking acpi settings and dsdt - guess less bugs on those help a lot

did a test with bios reset to defaults + disable secure boot

all good except for applealc usage. i'll try other layout ids... https://github.com/acidanthera/AppleALC/commits/master/Resources/ALC255

What was happening when applealc made the kernel shoot to 70%, were you using a specific app?

That doesn't happen for me, which codec are you using I see you using layout 37, these are under a range of Realtek and Conexant.

Try a different hda layout that works and see if the issue repeats.

You could also generate your own layout xml and sumbit to applealc github to approve or patch it on your own with a new ID

I am trying to install Sonoma 14.4.1,

Apparently after the second reboot in pre-installation it now runs a checks for a graphics card device-ID, this happens even if you boot using -igfvesa, I am redoing the installation and a bios reset on my Dell 5520 to be sure.

EDIT:

Ill just downgrade to Ventura 13.6.6

Its actually really easy to open and edit snapshots in Sonoma for me, I tried catalina Catalina 10.15.7, however after i installed both kexts using hackintool and configured my config.plist to be similar to yours all i got was the Kernel Panic, nblue kext was the cause, and the dependencies were in Lili and virtual smc, I used MacbookPro14,1 and Ventura 13.6.5, picture added.

yes the patches are for ventura only. but you can try to change them

// AppleIntelFramebufferController::hwSetMode skip hwRegsNeedUpdate
		static const uint8_t f2[] = {0xE8, 0x31, 0xE5, 0xFF, 0xFF, 0x84, 0xC0, 0x74, 0x3D};
		static const uint8_t r2[] = {0xE8, 0x31, 0xE5, 0xFF, 0xFF, 0x84, 0xC0, 0xEB, 0x3D};
		
		//catalina
			static const uint8_t f3[]= {0xe8, 0x38, 0xe7, 0xff, 0xff, 0x84, 0xc0, 0x74, 0x3d};
			static const uint8_t r3[]= {0xe8, 0x38, 0xe7, 0xff, 0xff, 0x84, 0xc0, 0xeb, 0x3d};

i disabled panic for ventura patches

update

not panic on patches make them not tobe applyed bylilu. so they need tobe separated

so i fix the catalina code and it is working

no matter what i do i just cant make wahtevergreen patches work for me...

catalina code patched should work with no injection

Should I inject platform-I'd or device-id?
