It doesn't give errors only like this

IOReturn Gen11::validateDisplayMode(void *framebuffer, uint32_t mode, void const **modeDescription, IODetailedTimingInformationV2 **timing){
	auto ret =FunctionCast(validateDisplayMode,callback->ovalidateDisplayMode)(framebuffer,mode,modeDescription,timing);
	if (timing != (IODetailedTimingInformationV2 **)0x0) {
		auto displayTimingInfo = const_cast<IODetailedTimingInformationV2 **>(reinterpret_cast<IODetailedTimingInformationV2 **>(timing));
		(*displayTimingInfo)->pixelClock = 785400000;
	}
	return ret;
}

is possible?

	auto ret =FunctionCast(validateDisplayMode,callback->ovalidateDisplayMode)(framebuffer,mode,modeDescription,timing);
	if (timing != (IODetailedTimingInformationV2 **)0x0) {
		auto displayTimingInfo = const_cast<IODetailedTimingInformationV2 **>(reinterpret_cast<IODetailedTimingInformationV2 **>(timing));
		(*displayTimingInfo)->pixelClock = 785400000;
	}
	return ret;
}

Same kp "com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer : __ZN24AppleIntelBaseController13GetLinkConfigEP16AGDCLinkConfig_tS1_ + 0x492"

 

If I put

displayTimingInfo->pixelClock = 785400000;

got error at compilation "Member reference base type 'IODetailedTimingInformationV2 *' is not a structure or union"

k so previous fix works. if it doesnt just disable the code

 

got a hang at hwConfigureCustomAUX() gonna disable it by default in nblue

 

try check the vdd function i posted earlier

 

 

guess option is disable pixel code inside. if it panics then disable the call

validateDisplayMode()

so only issue is powewell call - maybe you can find a new patch. linux says no pg2 for your card

and

test the firmware loading

 

still we don't really know where the problem is

 

you can also try to test the production version. check what needs tobe enabled/disabled. the stolen memory warn can be fixed in laptop bios

 

 

and now that youre not so bad at coding you can try system icl framebuffer

 

linux check always help. there are so many for your display. 

 

 

this1 is funny
