[Acer PT14-51 Laptop] HowTo

[jalavoui]

u miss the parameter (sys.kc or boot.kc)

 

 

btw i use this to debug decompkernelcache. guess pass the parameter should work

anyway to step debug comment fopen and choose sys or kc fopen

 

don't hack my hack

One question... but if i patch the AppleIntelICLGraphics driver.. how can i restore it in system/Library/Extensions the patched one?

[Stezza88]

Got this situation in ghidra... so bad... 0x3ed .. variable __data i think..

you dont patch the binary directly use wg or nblue todo it.

 

did u make ghidra analyse the binary 1st?

 

just testing for this

 

 

if i try this in the ventura binary from decompkernelcachede

 

 

ghidra failed to decompile the code and i get this

 

 

 

this is bad luck but you can load on ida pro

 

[jalavoui]

when you create the patch (new bytes) add to nblue or wg like this

f2 are original bytes

r2 is the patch (new hex bytes copyed from ghidra or ida pro)

 

so you don't mess with the binary files. you just create patches to use on nblue or wg

[jalavoui]

i you find code that you just can't decompile better (china code) like this (**(code **)(*in_RDI + 0x178))();

ask on the other thread - maybe visual helps you

i did test last night the config and acpi you did for me jala, it tries to boot (im using sonoma 14.7 from a usb) without nblue or weg fork it goes to a blank screen only. should i add reset nvram driver?

[jalavoui]

the config i did was based on my oc old 9.6 version. try to change it for the version you have

 

this is my oc confg

 

it's old just get OC + OC confgurator that can let you do proper configs

 

if you read this thread you will see everyone does mistakes. so we talk about it here and try to find a solution

 

asus for instance took 5 pages to figure out his nvram delete mistake

 

so ben i think if you can fix the new config your system will work just fine

Hope IDA 7.7 could do its dirty job too.. now i'm setupping some things..

dont try in windows get ida pro for mac os it's free. better not use windows ever

I have found this... it was "com.apple.driver.AppleIntelICLGraphics : __ZN16IntelAccelerator10getGPUInfoEv + 0x3ed"

And maybe i thought that 0x3ed is the offset inside this function..

In my code for example, i don't have this sequence of byte so the lshbluesky patch won't apply

// Sku Bypass IntelAccelerator::getGPUInfo
static const uint8_t f2[] = {
	0x0F, 0x87, 0x17, 0x01, 0x00, 0x00, 0x48, 0x8D, 0x0D, 0x96, 0x02, 0x00, 0x00
};

when i find, it's empty the search

I did my patch, and it worked!! I've followed lshbluesky methodology (pointing to a safe location) in the other post to do it..

// Sku Bypass IntelAccelerator::getGPUInfo
static const uint8_t f2[] = {
	0xE8, 0x38, 0x0C, 0x06, 0x00, 0xE9, 0x2D, 0x01, 0x00, 0x00
};
static const uint8_t r2[] = {
	0xC7, 0x83, 0x98, 0x11, 0x00, 0x00, 0x08, 0x00, 0x00, 0x00
};

Noi i have got a new kp... "Graphics Firmware Load failed boot hash check!\"

Kernel-2024-11-03-115328.panic

 

But this has no instructions associated... it could be a problem..

With -disablegfxfirmware boot arg kp disappeared but It loops on "busy timeout iGPU"

that's interesting you're using scheduler for apple firmware and icl is trying to load it. kinda like linux

are you using wg from other thread?

i hacked it long ago to load tgl guc but it sure miss lots of work cause this wg patches are for old os x version. try scheduler 4 also it's non apple firmware. 5 is nblue tgl default

 

 

it's interesting your card is trying todo same as linux (firmware loading)

did you try with AppleIntelTGLGraphics also ?

 

igpu hang also happens on wg for framebuffer only? fix this first

you can also try to load icl or AppleIntelTGLGraphics without the framebuffer driver for testing (will produce some logs)

 

hope you can make nblue to work - much easier way to patch kexts

 

this is the correct. the offset of panic is always printed in kp msg - i think i posted something about this with a calculator print

 

make sure you check for the bytes in the binary for repeating. if f2 repeats in binary on some other function the patch will probably fail

sometimes is better to use bigger pattern to avoid that

[NBlue] But the .bundle files must be loaded too? In folder GPUBundle? How can I copy the AppleIntelTGLGraphics into S L E ?

 

[EDIT] With nblue (this is proof with com.apple.driver.AppleIntelICLLPGraphicsFramebuffer from S/L/E) is more complicated to me because i get no kp (= can't patch) .. i hang on this (same with *LE drivers)

 

Edited November 3 by ASUS Vivobook

[jalavoui]

you gotta break os x seal to install to /S/L/E. bad idea for now as you can't load any framebuffer

you can try /sle/AppleIntelTGLGraphics.kext + bundles +hookcase into /L/E just for testing. patches are in nblue

 

idk if putting bundles in /Library/GPUBundles would to anything put in /L/E 1st

 

hope you can solve that igpu hang issue either with wg or nblue

 

found a link error with nblue. gonna apply as nred - read other thread

[WEG] Tryed scheduler 4 and 5 .. nothing changed... same hang.. here some logs dump ..

What i obtain if i do this boot arg? Could be important?

1. Use the -igfxfbdump boot flag to dump native and patched framebuffer table to ioreg and then File->Import->IOReg Dump menu

[jalavoui]

i think wg framebuffer settings dont work for icl but give it a try

[Stezza88]

[NBlue] with ICLLE or TGLLE
