Im trying to test on Sonoma 14.2.1, however i receive the boot log error below?

 

Lilu       api: @ (DBG) got load request from NootedBlue (100)
Lilu       api: @ automatically disabling NootedBlue (100) on an unsupported operating system
NootedBlue      init: @ parent said we should not continue 4

 

Would I have to rebuild nblue for Sonoma? or is there a setting in nblues info.plist i can edit to allow it to load on Sonoma?

dont. it is ment to work in ventura (the patches i did)

 

for sonoma u need to guess new patches.

i'll upload a new release with comments on function patches to help

 

this will load on sonoma but need patch fix for sure

also i did

auto *prop = OSDynamicCast(OSData, this->iGPU->getProperty("AAPL,ig-platform-id"));

if (!prop)

        this->iGPU->setProperty("AAPL,ig-platform-id", builtin2, arrsize(builtin2));

 

so you can use opencore injection

i'm working on custom monitor injection properties atm

i comment the code so you can guess sonoma patches

 

update:

i've add display injection in info.plist

you can now use hackintool and inject a custom display in nblue (remove the sample i put)

Test 5
- WhenverGreen : Disabled
- IGPU Device Properties : do not inject
- boot-args : -nbluedbg -allow3d

- macOS Version : macOS Catalina 10.15.7

I get the same kernel panic whether I apply -allow3d or not.

plz test on ventura or sonoma only

 

I'm Sorry, but the kernel panic log is not visible in macOS Ventura 13.x version... 😢

During the boot process, it just stops without any kernel panic logs.

I will install macOS Ventura 13.x again later.

that's weird it looks like it is just hanging and not giving panic (wrong lilu or nblue is not after lilu in opencore list ?)

 

image.png.ba5eb702d3e0ccc214e5b2dc5f04e1d8.png

 

As shown in the picture, NBlue is loaded after Lilu.

I think a kernel panic actually occurred, but it doesn't appear in the boot log.

can you inject old AAPL,ig-platform-id ? the new code supports it

in nblue you now can disable some gpu settings in info.plist

 

i found a panic if other lilu addons also use _cs_validate_page

other addons can also make the system hang (cause of lilu calls)

 

this new info.plist logic allows to change some parameters

you guys can try change in NBlue the code for AAPL,ig-platform-id. it's set to {0x01, 0x00, 0x52, 0x8A};

maybe disable and add manual id to opencore ?

 

i'm sure crashes depend a lot on the kind of laptop display that you use

i forgot to say that i'm not using any SSDT-PNLF - it means no backlight support for now

my boot args are debug=0x100 keepsyms=1 -vi2c-force-polling -allow3d

my bios settings: reset to defaults and disable secure boot

 

shl628

can you check the panic log with NBlue ? maybe patches are wrong for latest ventura or your hardware needs something specific to work

do not use whatevergreen with nblue

in nblue i only changed in info.plist the SupportDynamicCDClk setting

 

this are the lilu debug and kernel sdk that i'm using (can get them elsewhere anyway)

 

Arquivo.zip 4.47 MB · 7 downloads

 

so i reverted the SupportDynamicCDClk to 1 and disable 1 patch in nblue. working fine for me (the screen flicks a bit during boot)

if you guys wanna test other cards ids just edit the info.plist of nblue

 

 

i know my deviceID for my iGPU is 9a688086, idk what AAPL IGPU platformID i need to use for it with nblue or other settings in deviceproperties in OC to add tbh. I checked on google no luck or elsewhere. Same with the kext's code, i just got the laptop 1 or 2 months ago as i said, i dont know it well enough to know what AAPL i need.

manged to detect the micron nvme (isn't this a unsupported nvme disk?)

 

need to enter bios and disable intel vmd setting near sata ahci options (use the advanced bios mod i posted earlier)

i have disabled turbo mode cause in os x the cpu just burns with it enabled

on 1st reboot need to enter windows safe mode to update settings

 

anyway just in case i updated the NVMeFix.kext with linux 

    { 0x1344, 0x6001,   /* Micron Nitro NVMe */
              NVME_QUIRK_BOGUS_NID, },
    
    { 0x1344, 0x5407, /* Micron Technology Inc NVMe SSD */
             NVME_QUIRK_IGNORE_DEV_SUBNQN },

lol my disc id is 0x1344 but 0x5411 not in quirk list

no need to use SSDT-NVME_OFF.aml etc

trim is enabled by default

without intel vmd the disc mode pushes the fans a lot. is there a intel vmd driver for macos or linux ?

grats javavoui, but yeah im struggling to figure out what settings i need in OC and nblue to attempt to get my iris xe graphics going. Can you and/or sky help me? i know my laptop is an asus tuf f15 fx506heb

Can I use any other properties, device-id etc, or only "AAPL,ig-platform-id" for now,

 

I originally disabled the PciRoot(0x0)/Pci(0x2,0x0) key itself while doing my inital first tests with nblue on SOnoma, I was using MacbookPro16,2 though,

 

image.png.a4f69343471505af947cad139d9a3f86.png

 

When trying AAPL,ig-platform-id - 0000538A with macbookpro14,1 with debug=0x100 keepsyms=1 -vi2c-force-polling -allow3d  as boot arguments, i get a big stop sign, im guessing thats because im trying to boot sonoma with macbookpro14,1

 

Also are you using any acpi patches, also are you using the emulate option in opencore or are you using lilucpu=X?

 

image.thumb.png.ba028ee41a1120c3fade13a3f57e58ad.png

 

usually when you are emulating a specific igpu, you use the generation processor its on, or can i get away with cometlake or icelake emulation?

 

Edit:

when using Macbookpro16,2 and nblue, i get the below kp, i had disabled applealc and intelbluetooth and weg already (those are the main lilu plugins), dont have broadcom kexts, it says its apple smc thats causing the kp, but virtualsmc is need in order to boot, and the smc plugins might be making the calls. those are like Im smcbattermanagerkext etc,  I could be wrong.....

Test 6
- WhenverGreen : Disabled
- IGPU Device Properties : AAPL,ig-platform-id = 0200518A, etc...
- boot-args : -v keepsyms=1 debug=0x100
- macOS Version : macOS Ventura 13.6.5

 

Regardless of whether the value of SupportDynamicCDClk is 0 or 1, booting stops as shown in the photo below.
I have the same problem even if I inject various Platform IDs using the AAPL,ig-platform-id property.
Also, the same problem occurs when -allow3d boot arg is applied.

In my opinion, this needs a patch to resolve the Unsupported CD Clock Frequency kernel panic.
Of course, I understand that you said WEG must be disabled.
However, the above booting problem can be solved by adding only the -igfxcdc option in the current Test6 setting conditions.

 

If I also add -allow3d boot arg here, the "Unexpected context status buffer entry" kernel panic below occurs.

Unexpected context status buffer entry KP.txt

 

Spoiler

image.thumb.png.a5bdb135e330f0e7d48614a769e8a54c.png

 

I'm sorry, but would it be a bit difficult to add WEG's CD Clock patch module to NBlue?

Or, is there a binary patch that can bypass Unsupported CD Clock Frequency kernel panic?

 

Additionally, I just noticed that display-related settings have been added to NBlue's Info.plist.
I will test this too.

 

+ After adding igfxfw=2 boot arg, Unexpected context status buffer entry kernel panic was resolved and booting was possible.

However, graphics acceleration does not work yet.
And, my IGPU boot log is now almost similar to jalavoui's IGPU log.
I also get the following log output :

In my history I found intel graphics dependency on some SMC keys different on SMBIOS. I added these keys into FakeSMC and obtained the result. If this is the similar case then we need a new development.

Heres the Intel_reg dump, my card is the 9A49, same as the OP

 

intel_reg dump.txt

 

These are a few test via Terminal in Buntu 22.04, writing most of these values turned off the backlight or made it go dim, im online working tonight, so I can run the test you need in another 3 hours once im settle down. Or most of tomorrow its my day off.

can any post linux logs ?

 

I am attaching the Dmesg log and all logs in the /var/log directory.

1. Test changing the GraphicsSchedulerSelect value without igfxfw=2

 

1-1. GraphicsSchedulerSelect = 0 (Default, unmodified NBlue's Info.plist)
Unexpected context status buffer entry kernel panic.

 

1-2. GraphicSchedulerSelect = 1
Unexpected context status buffer entry kernel panic.

 

1-3. GraphicSchedulerSelect = 2
Unexpected context status buffer entry kernel panic.

 

1-4. GraphicSchedulerSelect = 3
Unexpected context status buffer entry kernel panic.

 

1-5. GraphicSchedulerSelect = 4
Unexpected context status buffer entry kernel panic.

 

1-6. GraphicSchedulerSelect = 5
Unexpected context status buffer entry kernel panic.

 

2. Test changing the GraphicsSchedulerSelect value with igfxfw=2 applied

 

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 = 1
Stuck on AuxKC loading process during boot.
Forced restart shortcut (Ctrl + Command + Power Button) does not work.

 

2-3. 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.

 

2-4. GraphicSchedulerSelect = 3
It boots, but logs show firmware load failure and graphics acceleration does not work.

Same as IGPU log in Test6 result above.

 

2-5. GraphicSchedulerSelect = 4
Stuck on AuxKC loading process during boot.
Forced restart shortcut (Ctrl + Command + Power Button) does not work.

 

2-6. GraphicSchedulerSelect = 5
Unexpected context status buffer entry kernel panic.

check 

 

try boot linux with that param and get /var/log/syslog

output should look like this

 

[ 2.014699] Setting dangerous option enable_guc - tainting kernel [ 2.019971]

[drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) [ 2.030651]

delete syslog if it gets huge and reboot linux

 

we need to load fwLoadMode == FW_GENERIC. i changed the info.plist but atm no way to force load tgl_guc_70.1.1.bin

 

__int64 __fastcall IGScheduler::canLoadFirmware(IGScheduler *this, IntelAccelerator *a2)
{
  int v2; // eax

  v2 = (*((_DWORD *)this + 1136) >> 22) & 7;
  if ( v2 == 4 )
    return IGScheduler4::canLoadFirmware(this, a2);
  if ( v2 == 3 )
    return IGGuC::canLoadFirmware(this, a2);
  return 0LL;
}

See attached.

 

My syslog was over 10Mb so its here, I didnt get the "Setting dangerous option enable_guc - tainting kernel" Warning, maybe i should modify the boot entry a little more?

 

https://www.mediafire.com/file/avbh7yvwx7c2fz0/syslog/file

 

there were some other files in the /var/log folder, theyre here:

 

https://www.mediafire.com/folder/6mgbdnf54xvfl/Buntu

 

i used live ubuntu from a USB, i just modified the grub config to the below for 22.04

 

set timeout=0

loadfont unicode

set menu_color_normal=white/black
set menu_color_highlight=black/light-gray

menuentry "Ubuntu" {
    set gfxpayload=keep
    linux    /casper/vmlinuz persistent file=/cdrom/preseed/ubuntu.seed ro quiet splash drm.debug=0x14
    initrd   /casper/initrd
} 

menuentry "Try or Install Ubuntu" {
	set gfxpayload=keep
	linux	/casper/vmlinuz persistent file=/cdrom/preseed/ubuntu.seed  quiet splash --- 
	initrd	/casper/initrd
}
menuentry "Ubuntu (safe graphics)" {
	set gfxpayload=keep
	linux	/casper/vmlinuz nomodeset persistent file=/cdrom/preseed/ubuntu.seed  quiet splash --- 
	initrd	/casper/initrd
}
menuentry "OEM install (for manufacturers)" {
	set gfxpayload=keep
	linux	/casper/vmlinuz persistent file=/cdrom/preseed/ubuntu.seed only-ubiquity oem-config/enable=true quiet splash --- 
	initrd	/casper/initrd
}
grub_platform
if [ "$grub_platform" = "efi" ]; then
menuentry 'Boot from next volume' {
	exit 1
}
menuentry 'UEFI Firmware Settings' {
	fwsetup
}
else
menuentry 'Test memory' {
	linux16 /boot/memtest86+.bin
}
fi

I'll install Ubuntu onto a second ssd and then add that as the root in the grub.cfg later, seems there is another way to do it.

Using nblue Bin on IDA or Hexfiend?

 

dont see that in nblue Master

 

Also my Video Bios got corrupted somehow, even after reinstalling Ventura, the same issue persist, interesting.

 

I cant even boot the ventura 13.6.5 installer using the same EFI i had created before,

 

Resetting bios didn't fix it, I had to re-install my bios via recovery
