Hello everybody,

I'm currently patching a DSDT w/ corresponding SSDTs for an ASUS N750JK (it is not for myself). The system information is as follows:
- Intel® Core™ i7 4700HQ Processor
- Intel® HM86 Express Chipset
- Intel® HD Graphics 4600
- Nvidia GeForce GTX 850M (switching technology)
- Realtek RTL8188CU wireless LAN 802.11n -> replaced with BCM43xx w/ BT 4.0 combo.
- Realtek PCIe GBE ethernet controller
- Realtek PCIE CardReader

There are 8 SSDTs extracted by using a Linux bootable disk, of which the last one (number 8) was in the dynamic folder on the Linux boot. I did include SSDT8 with decompiling as I thought it may help solving some external references (I couldn't find it in the guide exactly whether you'd need to in/exclude the dynamic ones with disassembly, but I included it anyway). So, after that I checked each file for what I think it's 'main purpose' is and SSDT7 is AFAIK mainly responsible for some graphics handling (GFX0 and PEG).

So far I followed the DSDT/SSDT patching guide by Rehabman and extracted everything from Linux (as you could read previously). Also installed latest MacIASL App and CLI binaries from Rehabman's repositories today (support for ACPI 6 spec). Some errors were resolved by using this latest v6.

I've been able to get the DSDT and all SSDTs error-free as that is my first step before I'm starting to patch 'em. However, in SSDT7 is a method and I get a syntax error there (PARSEOP_NAMESEG). The bit I'm referring to is this:
Code: 
Method (WMMX, 3, NotSerialized)
{
    CreateDWordField (Arg2, Zero, FUNC)
    If (LEqual (FUNC, 0x534F525F))
    {
        If (LGreaterEqual (SizeOf (Arg2), 0x08))
        {
            CreateDWordField (Arg2, 0x04, ARGS)
            CreateDWordField (Arg2, 0x08, XARG)
            Return (\_SB.PCI0.PEG0.PEGP._ROM (ARGS, XARG))
        }
     }


    If (LEqual (FUNC, 0x4D53445F))
    {
        If (LGreaterEqual (SizeOf (Arg2), 0x1C))
        {
            CreateField (Arg2, Zero, 0x80, MUID)
            CreateDWordField (Arg2, 0x10, REVI)
            CreateDWordField (Arg2, 0x14, SFNC)
            CreateField (Arg2, 0xE0, 0x20, XRG0)
            If (CondRefOf (\_SB.PCI0.GFX0._DSM))
            {
                Return (\_SB.PCI0.GFX0._DSM)
                MUID
                REVI    // This is the problematic line.
                SFNC
                XRG0
            }
        }
    }

    Return (Zero)
}

Thus, the question: What do I need to do to fix the error? I have included all files in a zip, attached to this post, just in case the code snippet is not enough.

In the file are 3 sets:
- Extracted -> raw files from the Linux.
- Decompiled -> the decompiled files from the extracted folder.
- Patched -> patched decompiled files.

Hope somebody can help me with this.

I guess I fixed it. I applied the [gfx0] Cleanup/Fix Errors (SSDT) patch from Rehabman's laptop patch repository. Now there are no more errors.

@Wcool93
Could you please more specific about which patch you used to resolve this error?
I am receiving the same error on one of my SSDTs, and I believe not being able to patch that SSDT with the PNLF patches is preventing me from being able to control monitor brightness.

The line I am getting the error on is "REVI" under "Return (\_SB.PCI0.GFX0._DSM)".


Attached is the SSDT which has been disassembled using the "iasl -da -dl -fe refs.txt *.aml" command

                Return (Zero)

Apply "Fix/Cleanup Errors [SSDT]" from my laptop repo.

But you don't need to patch SSDTs for brightness control. As per guide, you need only "Brightness Fix" to DSDT + IntelBacklight.kext.
 
Thank you very much for the quick reply @RehabMan !
I very much appreciate all of the work you have put into helping us all! I have relied heavily on the documentation and patches you have provided.

I didn't see the patch you referred to, but I had dowloaded the patches to my laptop rather than added as a repo to MaciASL.
So, I added it your GitHub as a repo to MaciASL and was able to find it.
I applied it, and now it compiles correctly!

Now I am going to see if having that patched fixes my brightness issue. If not, I am going to try and track down that IntelBacklight.kext.
I am currently using the APCIBacklight.kext.
 
Haha, I read through that guide a few times, and completely overlooked the IntelBacklight kext portion...

I am going to reapply all of my patches now, and see if that will work.

Thanks!

I'm currently having this 15293, 6126, syntax error, unexpected PARSEOP_NAMESEG, expecting '(' error, the problem is that the patch that is mentioned here as solution, is for SSDT and I'm working with an DSDT...
