Unable to get XPS 15 2-in-1 9575 HD 630 work in 10.13.4

[RehabMan]

I only find _OFF in SSDT-12-AmdTabl.dsl:

Scope (\_SB.PCI0.PEG0.PEGP)
    {
        Method (_ON, 0, Serialized)  // _ON_: Power On
        {
            \_SB.PCI0.PGON (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }

        Method (_OFF, 0, Serialized)  // _OFF: Power Off
        {
            \_SB.PCI0.PGOF (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }
    }

and

If (LEqual (Arg0, 0x02))
            {
                CreateWordField (Arg1, Zero, FN2S)
                CreateByteField (Arg1, 0x02, DGPR)
                If (LEqual (DGPR, Zero))
                {
                    \_SB.PCI0.PEG0.PEGP._OFF ()
                }

                If (LEqual (DGPR, One))
                {
                    \_SB.PCI0.PEG0.PEGP._ON ()
                }

                Return (Zero)
            }

There is no _INI similar to the case in your post however..

For the case of _INI not present (relatively common with recent laptops), you just add _INI before _OFF:

Method(_INI) { _OFF() }

Not all _OFF implementations have EC references. In such cases, less patching to do (no EC related code, no need to move it).

Like this?

Scope (\_SB.PCI0.PEG0.PEGP)
    {
        Method (_ON, 0, Serialized)  // _ON_: Power On
        {
            \_SB.PCI0.PGON (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }

        Method(_INI) { _OFF() }

        Method (_OFF, 0, Serialized)  // _OFF: Power Off
        {
            \_SB.PCI0.PGOF (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }
    }

I found _OFF in SSDT-2-PegSsdt.dsl ,too.

Method (_OFF, 0, Serialized)  // _OFF: Power Off
            {
                If (LGreater (OSYS, 0x07D9))
                {
                    PGOF (Zero)
                    Sleep (DLAO)
                    Store (Zero, _STA)
                }
            }

Not sure if I need to change this?

Not relevant.

Hi RehabMan, I tried the code

Scope (\_SB.PCI0.PEG0.PEGP)
    {
        Method (_ON, 0, Serialized)  // _ON_: Power On
        {
            \_SB.PCI0.PGON (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }

        Method(_INI) { _OFF() }

        Method (_OFF, 0, Serialized)  // _OFF: Power Off
        {
            \_SB.PCI0.PGOF (Zero)
            Notify (\_SB.PCI0.PEG0, Zero)
        }
    }

But it still restarts before getting into desktop. Am I doing anthingwrong?

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Disabling the Nvidia with ACPI is a post-install task, so the reboot problem is something new with the patch?

Yes, I was able to boot into desktop with 0x12345678 ig-platform-id. I'm now trying to use 0x591b0000 but the system reboots before gets into desktop. So I'm trying to disable AMD dGPU.

With the ssdt to disable dGPU, it still reboots before gets into desktop.

The ioreg was get from booting with 0x12345678.
It seems dGPU isn't disabled since AMD is still appeared in ioreg.

Hello, I've followed the guide to patch the DVMT through kext. The results are the same. System restarted immediately before get into desktop.

I used

Find <00001b59 00000000 3aaa0800 00000000 01030303 00006002 00005001>

Also, strangely, About This Mac shows 31mb:

This is the screenshot get from the debug mode debug=0x100 flag (so that it won’t reboot after KP)

Update: I found out I can "get into" desktop with ig-platform-id 0x59120000 without KP (Disks are shown reading, keyboard cap light functions); whereas, all other KBL ig-platform-id give me KP. It's just, however, the screen is black. I wonder if I can patch the connector-type of 0x59120000 to get the screen works since I think 0x59120000 is for desktops.
