update

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

So I should use Fake SMC then?

It is always good idea.

found the bug. the arrays need tobe same size for this to work. this code fails

LookupPatchPlus const patchesc[] = {

{&kextG11FB, f, r, arrsize(f), 1},

{&kextG11FB, f3, r3, arrsize(f3), 1},

};

LookupPatchPlus const patches[] = {

//{&kextG11FB, f, r, arrsize(f), 1},

{&kextG11FB, f2, r2, arrsize(f2), 1},

};

auto catalina = getKernelVersion() == KernelVersion::Catalina;

SYSLOG_COND(!LookupPatchPlus::applyAll(patcher, catalina ? patchesc:patches , address, size), "gen11", "Failed to apply patches!");

so just use this

auto catalina = getKernelVersion() == KernelVersion::Catalina;

if (catalina)

SYSLOG_COND(!LookupPatchPlus::applyAll(patcher, patchesc , address, size), "gen11", "Failed to apply patches!");

else

SYSLOG_COND(!LookupPatchPlus::applyAll(patcher, patches , address, size), "gen11", "Failed to apply patches!");

i just tested catalina and idk if it updated itself but the patches aren't working

anyway goal is focus on ventura so nvm

AND IT'S ALWAYS BETTER TO USE PANIC_COND cause it panic if patches aren't applyed

left is cata log and right is ventura

if the patch is applyed then the modeset by scaler is called and the screen won't turn black.

if the patch fails then you get complete modeset and a black screen

this works in the cata installer but not after os is installed...

maybe cause i have ventura and cata on same disk ?

confirmed - i just patched the binay on disk and it works

howto?

in cata mount uw / as root

patch the framebuffer file

force kextcache to rebuild

side effect - need to bring back SYSLOG_COND to avoid panic for cata

Are you using Ventura 13.6.5 or 13.6.6?

The issue I was highlighting in my previous image was when using Ventura 13.6.5 with a similar configuration to yours, it differs slightly because of Dell hardware need some extra quirks smbiosguid etc

Also can you share the plist that you are using to boot ventura currently? Not sure if you are using the same plist as a couple posts up.

jalavoui · April 5

latest ventura always. yes i'm using same oc config

logs from vent and cata (with and without the binary patch)

i see a lot of bugs but guess can be ignored as the framebuffer is working

i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/tgl_dmc_ver2_12.bin (v2.12)

	const struct firmware *fw = NULL;
	const char *fallback_path;
	int err;

	err = request_firmware(&fw, dmc->fw_path, i915->drm.dev);

	if (err == -ENOENT && !i915->params.dmc_firmware_path) {
		fallback_path = dmc_fallback_path(i915);
		if (fallback_path) {

			err = request_firmware(&fw, fallback_path, i915->drm.dev);
			if (err == 0)
				dmc->fw_path = fallback_path;
		}
	}

	parse_dmc_fw(dmc, fw);

	if (intel_dmc_has_payload(i915)) {

		drm_notice(&i915->drm, "DMC firmware homepage: %s",

so this code

if (intel_vgpu_active(i915)) {

drm_notice(&i915->drm,

"iGVT-g active");

return -ENOSPC;

}

drm_notice(&i915->drm,

return -ENOSPC;

}

better to disable intel vt-d in bios ?

or keep it no issues

this is intel way of assign metal family (rip amd)

atm nblue doesnt have framebuffer injection properties like busid, etc

but the info.plist allows changing a few properties

i'll try add a section to allow changing framebuffer properties kinda like whatevergreen

this are the base values

altough no acceleration and wrong connectors this release is fine

need others to change it for non working displays

your log looks like typical hang when loading scheduler 4 or 5

the default atm is 3 so idk what is causing the hang

unless you have same display as me and this config breaks it (i doubt)

This is my display info exported using hackintool, reason im looking at my edid is to see if its missing some properties needed.

Should i update nblue's info.plist using these values, or should i try to set it to be spoofed to a macbookair in hackintool first?

Also if im editing that info, should i edit the values in the display Apple ID Injection Array (More Likely) or theIOProviderMergeProperties (Less Likely)

just disable it. you need to figure out why the driver fails. maybe try get syslog from hacintool

i updated code with (base code is in whatevergreen - this is just the property added to info.plist)

and no more screen flick at boot

image.png.75fcde6d7c921ebd4033cbd156f833bc.png

question: does any1 knows other hidden properties that can help us ?

for logs i use this in terminal

log show --style syslog --predicate 'processID == 0' --last 1h --info --debug > x.log

i've posted some log samples few posts ago

they dont need any special flags

as i said i have NO idea how to do majority of what you guys are doing. all I know how to do is copy and replace kexts and try them. Beyond that, i'm clueless tbh.

Mastachief · April 9

I will do a change of my EFI folder for the USB, and add opencore debug, ill upload that log by tomorrow, the log was generated, but then its not show the debug lines,

@jalavoui Whats the Debug NVRAM flag for nblue?

shl628 · April 10

@Mastachief You can check it in the kern_start.cpp source file.

static const char *bootargDebug = "-NBlueDebug";

@jalavoui When I booted using the most recent NootedBlue.kext, it stopped at the photo below.

- WhenverGreen : Disabled
- IGPU Device Properties : do not inject
- boot-args : -v keepsyms=1 debug=0x100 -NBlueDebug
- macOS Version : macOS 13.6.5(22G621)

So, I edited the log output section for the patch in NootedBlue's source code using Xcode, built it, applied it, and then rebooted, and a log like the picture below was output.

Logs for the kextG11FB patch were output, but no logs were output to determine whether the 7 patches (f2, f2b, f3, f3a, f3b, f4, f4b) for kextG11HW were applied correctly or not.

Of course, before modifying NootedBlue's source code, I tried booting with PANIC_COND instead of SYSLOG_COND, but the kernel panic log did not appear on the screen and it just stopped.

In kern_gen11.cpp, are the f1, r1 patches of kextG11FB patches to bypass Unsupported CD Clock Frequency kernel panic?

this is intel way of assign metal family (rip amd)

atm nblue doesnt have framebuffer injection properties like busid, etc

but the info.plist allows changing a few properties

i'll try add a section to allow changing framebuffer properties kinda like whatevergreen

this are the base values

altough no acceleration and wrong connectors this release is fine

need others to change it for non working displays

current boot flag: -v

Are you referring to the recent post above?

I used NootedBlue.kext from the post above.

jalavoui · April 10

yes. idk why not working for you

keep the PANIC_COND it helps if patches fail to aplly on old ventura versions

maybe lilu version issue ?

this is 1.6.7 i'm using

Lilu.kext.zip

latest patches stoped opengl crash in windoserver

framebuffer mode is very fast on this platform

I applied the most recently uploaded NootedBlue.kext and the Lilu.kext you attached and booted, and booting stopped as shown in the picture below.

from your whatevergreen logs maybe you need something else

try add this patch to your custom whatevergreen version

// 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};

show the boot log if it works

i just found that editing edid inside nblue info.plist brings back missing 60hz

guess more advanced settings can be done using this. hdpi ress seem to work

Capturadeecra2024-04-13as01_05_03.png.01e0c0022fcc47fc8435c550fdca0bfd.png

deleting this key makes nblue hang at boot

deleting its contents is fine

by default this does nothing. it's just a sample

to change get hackintool and replace the key after fix vendor/product

awesome work guys, i booted with ventura 13.6.6 on my laptop, it worked but i hadn't correct vram or opengl and metal. Nothing, idk why, i had the newest nblue linked and ilu 1.6.7 beyond that as i said before i dont know how else to fix it nor how to do kext edits and patching.

@jalavoui Adding that binary patch to the WhateverGreen source code was a bit difficult for me, so I tried using the framebuffer-patchN-find/replace property instead.

image.png.971cbfb4a039c31aad354b29af3d1e98.png

It boots, but a black screen issue occurs.

After checking the log using the screen sharing function, it seems that WEG's framebuffer-patchN-find/replace patch property is not working well.

[   26.892387]: WhateverGreen      igfx: @ (DBG) patch 0 framebufferId 0x8A710000 failed
[   26.892401]: WhateverGreen      igfx: @ (DBG) patch 1 framebufferId 0x8A710000 failed
[   26.892415]: WhateverGreen      igfx: @ (DBG) patch 2 framebufferId 0x8A710000 failed

So, I opened the Framebuffer dump file (AppleIntelFramebuffer_15_22.6) I uploaded before with the HexFiend app and looked for the corresponding binary value.

framebuffer-patch0-find : not found

E831E5FF FF84C074 3D

So, I searched for E831E5FF FF84C0 and found one.
I checked and it is already set to E831E5FF FF84C0EB 3D.

this modd works for me but without igfxagdc enabled you get crash logs in /Library/Logs/DiagnosticReports

i noticed the ring bug seems fixed

i just copyed some of your settings

update

with -v igfxagdc=0 you get rid of crash bug

i'm happy its 1st time i make whatevergreen work for me

@jalavoui Thank you for editing the WhateverGreen source code.

When I applied WhateverGreen.kext you attached, booting was successful and the black screen problem was resolved. 🙂

jalavoui · April 13

cool. maybe upload to your github ?

found the cause of

it's related with choose ig-platform

with yours this doesnt happen

from logs i got some things to watch

the wrong port/index (maybe try wahtevergreen patch for a good combo)

the stolen memory size (that you fixed by changing in bios)

the dvmt max bios memory (mine is capped to 256m, maybe change to maxdvmt?)

and why this ?
