the driver uses this "feature" that we don't need

i'm checking linux code

 

i think we need to get rid of this bs and use part of old icl code

Wait a second! Me and some other people managed to boot, install and use macOS normally, you should try too ;)

Sure, but some guidance would be appreciated. Let's take it somewhere else though, so we don't muddy the thread with non-dev talk.

a feature in nblue to disable dgpus?  i think can be done with opencore injection. i write about it but dont remenber where.

 

i do hope someone get xcode and try a few patches so we can get this done

 

as for non devs just try install it and post logs 

 

this patch isnt helping

tooke me 3 seconds to find this

try the opencore device injection patch

that was waht i ment

https://dortania.github.io/OpenCore-Install-Guide/extras/spoof.html

 

this part is what i used and tested

it works very well to disable the dgpu but make sure you put the right path

if working the device will vanish from ioreg

do this using opencore config tool

i've used that spoof method previously to inject the 9A49 platform-id instead of my native one, but same results. Did you intend to use it for another purpose?

 

Edit: got it, the injection method is to disable dGPU. note that might work for ˜50% of dGPUs, for the rest you will need to apply an ACPI _PS3 or _OFF call depending on your BIOS. My github has more details on how to do it precisely, it follows the OC-Little method...

i have an apple dev account and sequoia on my laptop, BUT im unsure what to do to patch the kext, i can build it but unsure HOW to patch the code though..

i deleted old sources and binarys to clean the thread.

 

latest nblue binary work with icl framebuffer (few posts back)

 

as for tgl  this are latest sources - hope some devs helps by publishing new code

 

NootedBlue-master.zip 410.74 kB · 12 downloads HookCase-master.zip 191 kB · 6 downloads

 

ok, let me try and contribute here. after some configuration, have successfully set up the source code, and built both kexts under xcode.

 

happy to start looking at which functions need to be looked at/uncommented first. just let me know which are the most important ones to start.

I tried both yesterday and today, but igfxutils can't detect my dGPU...

while i was playing with those apple internal kexts i managed to load the icl framebuufer.

the log is huge depending on IGLogLevel=8 number

but the advantage of getting proper logs + usage of many parameters not present on production version is huge

 

here's the bin and logs. you need hookcase  + previous sle_internal installed to /L/E

 

now it's so clear why many cards dont work - all is in the new logs

this latest version doesnt detect the iGPU (46a6 or 9a49), and remains looping in text mode without any second boot. no KPs, no blank screen

theory

then in code DDIx is "index"

after this auto portindex we get pipes

idk where bus id is used

From Hackintool BUSID and IndexSection

 

Below is from the BUSID Section:

 

Proven by ApplelntelFramcbufferControllor::MapFBToPort, by a call to ApplelntelFramebufferController::getGMBuslDfromPort.

 

This is GMBUS (Graphic Management Bus) ID described in

 

Gen 9

https://cdrdv2-public.intel.com/ 690989/intel-gfx-prm-osrc-hsw-display.pdf

 

Gen 11

https://cdrdv2-public.intel.com/ 705833/intel-gfx-prm-osrc-tgl-vol-12-display-engine.pdf

 

 

The use could  be found in Intel Linux Graphics Driver source code:

 

https://github.com/torvalds/linux/blob/6481d5ed076e69db83ca75e751ad492a6fb669a7/drivers/gpu/drm/i915/intel_lrc.c

 

https://github.com/torvalds/linux/blob/6481d5ed076e69db83ca75e751ad492a6fb669a7/drivers/gpu/drm/i915/i915_reg.h

 

However, it should be noted that Apple identifiers are slightly different from Linux driver.

 

In Linux 0 means disabled, however, for Apple it has some special meaning and is used for internal display.

 

Other than that the values are the same:

     GMBUS_PIN_DPC    (4) HDMIC

     GMBUS_PIN_DPB    (5) SDVO, HDMIB

    GMBUS_PIN_DPD    (6) HDMID

     GMBUS_PIN_VGADDC (2) VGA untilBroadwell inclusive.

 

So basically you could use  4, 5, 6 for arbitrary HDMI or DisplayPort displays.

 

Since 5 supports SDVO (https://en.wikipedia.org/wiki/Seriat_Digital_Video_Out), it may also be used to support DVI displays.

 

Starting with Skylake VGA works via SOVO too (instead of a dedicated GMBUS_PIN_VGAODC id).

 

 

Below is from the Index Section:

 

Watch out, this is really messy (see ApplelntelFramebutferController::MapFBToPort}.

 

I am not fully sure why this exists, and recommend setting index to array index (i.e. the sequential number from 0).

 

The only accepted values are 0, 1, 2, 3, and-1 (0xFF).

 

When index is equal to arrayindex the logic is simple: Port with index 0 is always considered built-in {of LVOS type) regardless of any other values.

 

Ports with indexes 1-3  are checked against type, HDMI will allow the use of digital audio, otherwise DP is assumed.

 

Port with index 0xFF is ignored and skipped.

 

When index!= array index port type will be read from connector[index].type

 

Say, we have 2 active ports:

 

0 - [1]      buslD 4 type LVDS

1 - [2]      buslD 5 type DP

2 -  [3]    buslD 6 type HDMI

3 - [-1]    buslD 0 type Dummy

 

This will result in 2 framebuffers which types will be shifted:

0 - buslD 4 type DP

1 - buslD 5 type HDMI

 

In fact BuslD values are also read as connector[index].buslD, but are later mapped back via ApplelntelFramebufferController::getGMBuslDfromPort by looking up a connector with the specified index. The lookup will stop as soon as a special marker connector (-1) is found.

 

To illustrate, if we have 2 active ports:

 

0  - [1]    buslD 4 type LVDS

1 - [2]     buslD 5 typoDP

2 - [-1]    buslD 6 type HDMI

3 - I·1]       buslD 0 type Dummy

The result will be 2 framebuffers which types and the second buslD will be shifted:

0 - buslD 4 typoDP

1 - buslD 6 typeHDMI

 

It is also used for port-number calculation.

 

- LVDS displays (more precisely, displays withCNConnectorAlwaysConnected flag set) get port-number 0.

- Other displays go through index - port-number mapping: 1 - 5, 2 - 6, 3 - 7, or fallback to 0.

 

By following the above guide, thats how i came up with the Device properties for Intel Plus Graphics G7 and the alldata connectors patch using whatevergreen. instead of Zero the connectors i just assign different ID's to null them out. as the connector information differed between cannonlake and icelake, there were differences with the alldata, it was half the actual amount of values.

tks. for future ref i found the condition that is used to match port number to gmbus 

 

image.png.71aba61a304d8b9a67bb69f31009228b.png

 

in code this value is used if not zero

the requestes it calls are

wonder why i dont see this log line anywere

by changing the icl connectors with DDI zero up to 2 + some extra nblue patches the agdc policy no longer hangs i.e. no more junk logs in /library/logs

the pipe 0 or 1 setting also matters when crt function is called

the bus number allows i2c comm. i used 8 and got some strange reading (sould be bus zero not 8 anyway)

can't follow linux logic blindly but instead check how apple code handles this connectors info 

 

this are icl/tgl tcon changes (maybe need port to icl for proper power support?)

i just disabled hwreg patch in nblue - it is no longer needed. this was the 1st patch i've wrote to make display boot

 the code register red/write in tgl is

image.png.ec9ddbcc6187cfd1d74ae3d9aa07c1b7.png

 

this functions dont have such validations and are maybe ment for DG1 only displays ?

maybe this card work - Intel Corporation DG1 [Iris Xe Graphics] [8086:4908] - 

image.png.51b744622fa7d05ab805e48065b282f9.png

 

that's why they crash at bootdisplay setup ?

 

so who as this kind of display and can figure it out ?

 

i just left nblue with the minimun patches for it tobe tested (power and connectors)

as for icl it currently works but with wrong sleep/wake code

 the code register red/write in tgl is

image.png.ec9ddbcc6187cfd1d74ae3d9aa07c1b7.png

 

this functions dont have such validations and are maybe ment for DG1 only displays ?

maybe this card work - Intel Corporation DG1 [Iris Xe Graphics] [8086:4908] - 

image.png.51b744622fa7d05ab805e48065b282f9.png

 

that's why they crash at bootdisplay setup ?

 

so who as this kind of display and can figure it out ?

 

i just left nblue with the minimun patches for it tobe tested (power and connectors)

as for icl it currently works but with wrong sleep/wake code

i horrribly only have my 9a68:8086 laptop jala, sorry man..

Is this graphics card compatible?

 

No, Intel UHD Graphics 770 Never will work (4680).

 

Intel UHD Graphics 770 is based on Intel's 12.2 Architecture instead of the DG1 12.1 architecture.

 

Only Tigerlake, DG1, and Rocketlake has a chance by hacking the Iris XE driver for DG1 class cards to bypass compat checks.

Is it possible to reverse engineer?🥲
