[Acer PT14-51 Laptop] HowTo

[Stezza88]

Now, with only

{"__ZN19AppleIntelPowerWell21hwSetPowerWellStatePGEbj",releaseDoorbell},
{"__ZN24AppleIntelBaseController15enableVDDForAuxEP14AppleIntelPort", releaseDoorbell},

Got "pipe0 not enabled" message instead of calculated pixel clock and boot with black screen and square mouse

Black screen with square mouse is the thing that must be resolved.. it's the common problem

[Stezza88]

I've understand that this (it contains useful register for adl - they are in my linux sys log)

{"__ZN24AppleIntelBaseController16hwUpdateRegCacheEP21AppleIntelFramebufferP21AppleIntelDisplayPath",releaseDoorbell},

enable my pipe0

 

but this

{"__ZN24AppleIntelBaseController35hwCRTCToIODetailedTimingInformationEP21AppleIntelFramebufferP29IODetailedTimingInformationV2", releaseDoorbell},

give to me wrong calculated pixelclock so i think that instead of the doorbell should be better to implement the method.

 

I've tryed to implement it but it doesn't work like

void AppleIntelhwCRTCToIODetailedTimingInformation(void *that, int64_t param1){
	functioncast .. (that, param1)
}

maybe i'm no good

If you help me to understand how to implement this method, i guess i have good logs @jalavoui

It is needed to calculate right pixelclock, scale etc , and it do by itself (instead of your crt patch)

{"__ZN24AppleIntelBaseController35hwCRTCToIODetailedTimingInformationEP21AppleIntelFramebufferP29IODetailedTimingInformationV2", AppleIntelhwCRTCToIODetailedTimingInformation, this-> oAppleIntelhwCRTCToIODetailedTimingInformation},

?? AppleIntelhwCRTCToIODetailedTimingInformation(void *that, ?? param1){
	FunctionCast .. (that, param1)
}
