Dual unsupported cards possible ?

[jalavoui]

Can we use an unsupported IGPU and GFX0 ?

 

IGPU = 0x15d8

GFX0 = 0x6611

This text editor crashes the graphics

guess dual graphic card issue ?

 

fix is add this setting to ST

"hardware_acceleration": "none"

 

This fix power sleep issues:

 

 

In order to fix boot I used the linux bios dump and injected it on opencore

The vega10 igpu crash in opencl, opengl and metal still is not fixed

 

this patch allows smooth return in case of a metal crash (dyld_shared_cache_x86_64)

if i plug gfx0 i got no crashes in opengl/metal

 

plug igpu - some apps use gfx0 metal api and crash, others use correct igpu metal api and load fine.

 

disabling gfx0 in dsdt doesnt fix it

 

anyone tested https://github.com/NootInc/NootedRed on a desktop pc and care to comment?

 

tracked the metal crash to here

both cards might work in ventura 13.3

 

using OCLP the gfx0 works

 

the IGPU as a funny bug:

(AMDRadeonX5000HWLibs) [8:0:0] AMD Error:
(AMDRadeonX5000HWLibs) Unable to find matching firmware device type for device ID: 0x15D8

this is very good news

\

the update i used on  OCLP installed monterey 12.5 kexts (without 6000 kexts)

Crossfire on hackintosh ? lol

 

this kext allows booting with external gpu (GFX0) and use the accelerator provided by internal gpu (IGPU)

 

it disables the 4000 kext accelerator  

 

What I'm doing here is booting with the external gpu and using  the faster IGPU for metal/opengl

 

btw for devs code is this

void WRed::wrapSetupAndInitializeHWCapabilities(void *that) {
    FunctionCast(wrapSetupAndInitializeHWCapabilities, callbackWRed->orgSetupAndInitializeHWCapabilities)(that);
    getMember<uint32_t>(that, 0x98) = 0; 
}

this is applied to the booting card, i.e., the card u physical plug your screen

only ofc if you have a working "offcard" that loads the accelerator driver

 

this wont work with Nootedred or any kext that patches this function

maybe this helps for older macs?
