[Guide] Patching LAPTOP DSDT/SSDTs

Seems like I have some duplicates in aml file, because I can't transform it to dsl. But all files have another sizes. If I only transforming DSDT, then in MaciASL I'm getting unexpected PARSEOP_LOCAL0, PARSEOP_LOCAL0, PARSEOP_LOCAL0 and PARSEOP_LOCAL2 error. I don't know what to do now.
Thanks for help.

Your files have embedded External opcodes.
As per post #1, no need to use -da or -fe refs.txt: iasl -dl DSDT.aml SSDT*.aml
 
Hi Mr. Rehabman. I've got 2 questions...

- I'm using the config.plist that you publish in Github for Intel HD 5500 and i see that there are some patches in ACPI/DSDT, so shouldn't I patch my DSDT with the patches that are applied in the config.plist? I dont know if you understand me...

- With your guide i generated 1 DSDT file and 12 SSDT files. Should I use only the DSDT file? I read that you recommend that we shouldn't use the SSDT files that was generated.

Thanks in advance

Those patches are rename patches. As per post #1, rename patches are best accomplished via config.plist/ACPI/DSDT/Patches and not applied to the files you put in ACPI/patched.

Since your system has only IGPU, you will find no need to patch any of the SSDTs, therefore (as per post #1) none of them need be in ACPI/patched.

I'm about to patch my DSDT/SSDT files to get ready it to do some modifications but...

If I decompile the files with the direct
Code: 
iasl -dl DSDT.aml SSDT*.aml
method, I get for DSDT.dsl 0 warnings and 1 error:

synthax error, UNEXPECTED PARSEOP_ARG1 inside this part of the code:

Code: 
        Device (SAT0)
        {
            Name (_ADR, 0x00170000)  // _ADR: Address
            Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
            {
                If (PCIC (Arg0))
                {
                    Return (PCID (Arg0, Arg1, Arg2, Arg3))
                }

                If (CondRefOf (\_SB.PCI0.SAT0.SDSM))
                {
                    Return (SDSM)
                    Arg0
                    Arg1
                    Arg2
                    Arg3
                }

                Return (Zero)
            }

Tried all the synthax fixes from your repository (I can't even apply some of them) but without success. Tried to delete part of the code but without success.

If I decompile with declarations (refs.txt) method I get for DSDT.dsl 116 warnings and 1 error:

[Unknown ASL Compiler Exception ID] [MDBG (Method)] highlighting this line of code:

Code: 
OperationRegion (MDBG, SystemMemory, 0x7AF4A018, 0x00001004)

Tried with iasl51, iasl61 and iasl.

I attach my origin.zip folder, the DSDT.dsl compiled with 1st method and the DSDT.dsl compiled with the external declaration method.

Two choices:
- Since you know SDSM is not existing, therefore the CondRefOf result will always be 0, just remove the code:
Code: 
        Device (SAT0)
        {
            Name (_ADR, 0x00170000)  // _ADR: Address
            Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
            {
                If (PCIC (Arg0))
                {
                    Return (PCID (Arg0, Arg1, Arg2, Arg3))
                }
                Return (Zero)
            }

-OR-

- Disassemble with a refs.txt that has only the SDSM entry.

I did it with the 2nd method you suggested because the 1st still give me 2 errors, one the same highlighting Arg1 line.

Thanks again and have a nice sunday.

Arg1 line? What are you referring to?
 
Thank you so much, Mr. RehabMan! I learnt a lot from this. I'm translating this post to Chinese, could I beg your permission?

Also provided in the repo is "USB _PRW 0x0D (instant wake)" (0x0D and 0x6D are both common values for XHC/EHC/HDEF return from _PRW).

It seems this sentence is redundant. It should be moved to the sentence before.
