The first 

static const uint8_t f6a[]= {0xe8, 0x37, 0xa9, 0x30, 0x00, 0x41, 0x83, 0xbc, 0x24, 0x54, 0x01, 0x00, 0x00, 0x00, 0x0f, 0x88, 0xd2, 0x00, 0x00, 0x00};
static const uint8_t r6a[]= {0xe8, 0x37, 0xa9, 0x30, 0x00, 0x41, 0x83, 0xbc, 0x24, 0x54, 0x01, 0x00, 0x00, 0x00, 0x48, 0xe9, 0xd2, 0x00, 0x00, 0x00};

(modified because i won't found your) stalls on boot
        

The second 

static const uint8_t f6b[]= {0xbe, 0x04, 0x00, 0x00, 0x00, 0x48, 0x89, 0xda, 0x31, 0xc9, 0xe8, 0x8c, 0xac, 0x04, 0x00};
static const uint8_t r6b[]= {0xbe, 0x04, 0x00, 0x00, 0x00, 0x48, 0x89, 0xda, 0x31, 0xc9, 0x90, 0x90, 0x90, 0x90, 0x90};

boot but on black screen with conn0 as 

0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x02, 0x00, 0x00, 0x00, 0x18, 0x00, 0x00, 0x00,

No log but kp

Kernel-2024-11-10-221216.panic

 

But adding 

{"__ZN24AppleIntelBaseController15hwWaitForVBlankEP21AppleIntelFramebufferj",releaseDoorbell},

boot on black screen with square mouse and got logs

x.log

forget the agdc callback and agdc patch for now

this is the place of the agdc callback patch. maybe i forgot to zero some bytes

image.thumb.png.1f948e3769e3bf412b038ba8edb10a23.png

 

 

focus on

your last panic. it's probably a div by zero

image.png.fd3e6b9d1c5a325943d07e893b0a1e3b.png

 

so the code is here

image.png.86f59540497aa86c96f22e5449fe0ac6.png

 

change 75 2e to eb 2e

it's a simple jmp

 

hope this won't turn in a bunch of new errors. we aren't fixing the origin of the problem

found a cause (maybe 2 much hacks)

 

image.png.f48f16df2a411975e2ac8fbefe5c2639.png

 

check is here. but the value read is so wrong patching this might be a bad idea

 

this is link size check patch. 

 

image.thumb.png.94602b26b8a6d37a4a903e1e170f6e00.png

 

well you can try let me check bytes to change

k here you go changed bytes 0f 82... to 48 e9

use a bigger byte chain so they dont exist somewherelse

 

image.png.02a12a8efcc8a1998e53a556f532a847.png

 

the pixel value is wrong. idk why this happened. this patch will pass a wrong value...

 

image.png.bb5e9880f11ba5d152a0a03e4e506b5b.png

this is the field with the wrong value

don't you miss previous patches? 

 

the base patches are fine

 

ups i patched the wrong part of code. that previous patch is for link size check

 

this is the data size check

image.thumb.png.6236b194970dce35e9e2370d46b948c9.png

 

so change to a jump

this is not found let me chek

 

this is what i posted earlier. it exists

image.png.541eb07031efb57f44a390745eeb932e.png

 

lol i just read you tryed to hack my bytes

 

don't do that

 

bad things happen

 

so use this patch +data size check that i just posted

 

i wonder how you get that log without this patch.

image.png.9a2deda7ebe02155499fb1635326f160.png

 

but dam i was rigth all this problems is cause of bad agdc timmings

I downloaded the last sle internal, opened le tgl fb in IDA PRO and I don't found your byte sequence!!!! I found mine!

 

I find "E8 37 A9 30 00 41 83 bc 24 54 01 00 00 00 0f 88 d2 00 00 00" not yours! yours not exist

hmm sec.

 

you're right about E8 37 A9 30 00 41 83 bc 24 54 01 00 00 00 0f 88 d2 00 00 00

 

gonna reload the bin in ghidra

 

strange thing

 

k so ghidra as this bytes

 

e8 67 63 35 00 41 83 bc 24 54 01 00 00 00 0f 88 d2 00 00 00

 

and ida pro 

 

E8 37 A9 30 00 41 83 BC 24 54 01 00 00 00 0F 88 D2 00 00 00

 

can't find any of this bytes in binary with hexedit...

 

gonna check with bninja

 

got other bytes ...

 

well try with the bytes you found - guess it works

change last part 0x0f 0x88 to 0x48 0xe9

 

if you don't a kp with lilu message then the patch is found

yeah sometimes i get that bug. i think its a decompiler issue. when this happens i try other bytes.

sec

 

k this are bytes near the jump. check

 

find

0f 88 d2 00 00 00 48 ff 05 71 a5 0e 00 be a0 00 00 00

 

replace

48 e9 d2 00 00 00 48 ff 05 71 a5 0e 00 be a0 00 00 00

 

this bytes works. they exist in the binary. hexedit dont lie

image.png.08534b337d18b963a883ce087e5e4a0f.png

 

dam dissasemblers!!

 

data size bytes checked

find

0f 86 c8 00 00 00 f3 0f 11 45 d4 48 ff 05 9f 78 0e 00 bf 08 00 00 00

rep

48 e9 c8 00 00 00 f3 0f 11 45 d4 48 ff 05 9f 78 0e 00 bf 08 00 00 00

 

link pass bytes checked

find

0f 82 c8 00 00 00 f3 0f 11 45 d4 48 ff 05 80 77 0e 00

rep

48 e9 c8 00 00 00 f3 0f 11 45 d4 48 ff 05 80 77 0e 00

 

i dont like this hack but give it a try

link check failed? wtf let me see

 

the patch is ok. did u use the link patch?

 

right the pixel field as wrong value so the link patch not enough

 

let me try a field patch

image.png.b8ddf654e87c091ae9ad73d1eb5df399.png

 

so this means i'll hack the field to get this value...

image.thumb.png.a00ab445f9fffe8988b5a7dfeb30ec8c.png

 

k here they are 

 

find

84 c0 0f 84 dd 00 00 00 48 ff 05 80 7d 0e 00 49 8b 85 18 01 00 00

rep

84 c0 49 c7 85 18 01 00 00 00 e9 05 11 90 90 49 8b 85 18 01 00 00

 

the rep value is the previous pixel value 0x1105E900 = 285 600 000

 

this is very bad practice and i dont know the guy who did this !
