[Guide] Patching LAPTOP DSDT/SSDTs

[RehabMan]

Yeah, you are right!

Should I make a new thread for this issue? I will do that.

BTW, Thank you so much for such a long helpful conversation!

I think you will find many topics on Thunderbolt.
And I think you will find no clear answers/solutions. It is very much a work in progress (for a long time now) and very complex.

Good Evening/Morning,

I have this fresh installed High Sierra ( thanks to your guide and contributions @RehabMan ), so far, everything is working now, I even have patched Discrete GPU by following your guide and I believe it is working, however, I tried to work fresh, deleted and re-generated from Clover by F4, and the moment I try

iasl -da -dl -fe refs.txt DSDT.aml SSDT*.aml

AFTER

pbpaste>refs.txt

Following your guide, I get many errors, (I have attached Terminal Output, and required files from your guide, "Q. What are typical "Problem Reporting" files?")

Thank you so much for giving your so much time and effort. ​

Hello, could you fix the errors:

I dumped the aml files from Bios.

I used the code to disassembly aml files:

iasl -da -dl DSDT.aml SSDT*.aml

It gives me these:

I just disassembed ACPIs get from Clover instead, and convert them to asl with iasl.

But I always get errors when I compile them back. Could you help me convert the DSDT and SSDT aml files to asl, which I can compile?

I tried both

iasl -da -dl DSDT.aml SSDT*.aml

and

iasl -da -dl -fe refs.txt DSDT.aml SSDT*.aml

Neither DSDT asl files output are compilable with MaciASL.

No unusual errors with your files (with refs.txt, which is not required, or without it).
I disassembled: iasl -da -dl DSDT.aml SSDT*.aml
The only error is because of extraneous External(BNUM, which is addressed in the guide.

Thank you. I have done the whole process, no errors. Only step I skipped is creating and using refs.txt, is it okay? As you mentioned "which is not required", or I misunderstood?

Your files do not need refs.txt. refs.txt usually only needed with older ACPI sets that don't have embedded External opcodes.

Thank you sir. And thank you for explanation, I further researched and understood it even more now.
