Doesn't boot with Intel iGPU spoof enabled #11

Closed drizzt closed 3 years ago

drizzt commented 3 years ago

Hi,

I'm trying to launch Catalina installer on 20QE-SP40U (that is almost the same as 20QE-S01L00), but with default config it doesn't boot (it stucks after "IOConsoleUsers: gIOScreenLock..."). I already followed the guide without any success.

If I disable the Intel iGPU spoof it boots, with in VESA mode

Any clue?

I cant find hardware specs of your model. Could you please provide the CPU model?

drizzt commented 3 years ago

Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz with UHD Graphics 620 (Whiskey Lake)

I was getting that exact same issue as you a month or so ago but I could have sworn I fixed it. In fact, I know I did. However, I remember @suhrmann removed just a few things from my framebuffer patch and the EFI still worked on my machine so I thought nothing of it.

Let me dig up that original EFI with a very large framebuffer entry and let's see if that works for you. I have the exact same CPU as you and saw the same issue and this solved it.

Only mystery is why this is happening even when this current EFI W/O the huge framebuffer is working for me but not for you. Maybe some static register in the CPU or some garbo that I can't comprehend lol.

Give me a sec.

There's the config.plist that had all the framebuffer garbage that allowed me to get past giolockstate3 error. Please let me know if you have any issues copying it over.

config.plist.zip

I merged config.plist (by only replacing the PciRoot(0x0)/Pci(0x2,0x0) section) on top of last main and 1.0.0, but it still doesn't work

drizzt commented 3 years ago

Ok, I solved the problem by just adding -igfxmlr on top of 1.0.0

Ok good to hear. Thanks for reporting back. I'll mark and close this.
