My IGPU reads like this:

 

            Device (IXVE)
           {
               Name (_ADR, 0x00100000)
               Device (IGPU)
               {
                   Name (_ADR, Zero)

                   Scope (^^^PCI0)
                   {
                       OperationRegion (HDCP, SystemMemory, AMEM, 0x0600)
                       Field (HDCP, AnyAcc, NoLock, Preserve)
                       {
                           SIGN,   48, 
                           CHKS,   8,

                           GLOB,   4800
                       }
                   }

                   Name (ERR0, Buffer (0x04)
                   {

                   })
                   Name (ERR1, Buffer (0x04)

                       }
                       Else

                           If (LEqual (Arg0, 0x0C))
                           {
                               If (LEqual (Arg1, Zero))
                               {

                               }
                               Else
                               {
                                   If (LEqual (Arg1, One))
                                   {
                                       Store (GLOB, Local1)
                                       Concatenate (ERR0, Local1, Local0)
                                   }

                           }
                           Else
                           {
                               If (LEqual (Arg0, 0x0D))
                               {
                                   If (LEqual (Arg1, Zero))
                                   {
                                       Store (ERR0, Local0)
                                   }
                                   Else
                                   {
                                       If (LEqual (Arg1, 0x02))
                                       {
                                           Store (NVF2 (), Local0)
                                       }
                                   }
                               }
                           }
                       }

                       Return (Local0)
                   }

 

And I'm trying to add a _DSM Method that looks like this:

 

Name (_ADR, Zero)
Name (_SUN, One)
Method (_DSM, 4, NotSerialized)
   {
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }
    Return (Package()
           {
               "@0,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },
               "@1,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },
               "@2,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },
               "@3,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },
               "hda-gfx", Buffer() { "onboard-1" },
    })
   }

 

Everything I try comes back errors, could someone show me how this can be done, please?

The patch is for the _DSM with the parent_adr 0x00100000.


As you can see Device (IXVE) has a _ADR of 0x00100000.


It doesn't matter if I rename IGPU to GFX0 and I don't need the HDAU device.


I only need the "connector-type" properties and the "hda-gfx" to show up in the device tree in the IOReg.


 

# 4.  Insert device GFX0 and device HDAU (Nvidia/AMD HDMI audio)
into method label _DSM parent_adr 0x00100000 remove_entry;
into device name_adr 0x00010000 insert
begin
Device (GFX0)\n
{\n
   Name (_ADR, Zero)\n
   Name (_SUN, One)\n
   Method (_DSM, 4, NotSerialized)\n
   {\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
           {\n
               "@0,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@1,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@2,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@3,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "hda-gfx", Buffer() { "onboard-2" },\n
    })\n
   }\n
}\n
Device (HDAU)\n
{\n
   Name (_ADR, One)\n
   Method (_DSM, 4, NotSerialized)\n
   {\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
           {\n
              "hda-gfx", Buffer() { "onboard-2" },\n
    })\n
   }\n
}\n
end;

 

Here's how I'm doing it now:

 

 Device (PEGP)
           {
               Name (_ADR, 0x00100000)

               {
                   0x09, 
                   0x05
               })
               Device (GFX0)
               {
                   Name (_ADR, Zero)
                   Name (_SUN, One)
                   Method (_DSM, 4, NotSerialized)
                   {
                       Store (Package (0x22)

                               "hda-gfx", 
                               Buffer (0x0A)
                               {
                                   "onboard-1"
                               }
                           }, Local0)
                       DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                       Return (Local0)
                   }
               }


           }

 

But this gives me two Devices with the same _ADR (PEGP) and (IXVE) in my DSDT.

For what I understand you should replace original method _DSM in IGPU and add device HDAU, don't add devices PEGP and GFX0.


The correct patch would be

into method label _DSM parent_label IGPU remove_entry;
into device label IGPU parent_adr 0x00100000 insert
begin
   Method (_DSM, 4, NotSerialized)\n
   {\n
      If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
      Return (Package()\n
           {\n
               "@0,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@1,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@2,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@3,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "hda-gfx", Buffer() { "onboard-2" },\n
      })\n
   }\n
end;

Thanks. I only needed this part of the patch:

 

into method label _DSM parent_label IGPU remove_entry;
into device label IGPU parent_adr 0x00100000 insert
begin
   Method (_DSM, 4, NotSerialized)\n
   {\n
      If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
      Return (Package()\n
           {\n
               "@0,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@1,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@2,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@3,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "hda-gfx", Buffer() { "onboard-2" },\n
      })\n
   }\n
end;

 

It worked, somewhat, but for some reason the Drivers did not load the "Audio-Codec-Info" so I didn't get any codec loaded for my 10de,0007 HDMI Device, but your patch did show me where to insert my code, that I was using before, so now I only have one Device at _ADR 0x00100000, and that was the point.


Thanks so much.

I fooled with it a little more and came up with this:

 

into method label _DSM parent_label IGPU remove_entry;
into device label IGPU parent_adr 0x00100000 insert
begin
   Method (_DSM, 4, NotSerialized)\n
   {\n
      If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
      Return (Package()\n
           {\n
               "@0,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@1,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
               "@1,audio-codec-index", Buffer() { 0x03, 0x00, 0x00, 0x00 },\n
               "@1,av-signal-type", Buffer() { 0x08, 0x00, 0x00, 0x00 },\n
               "hda-gfx", Buffer() { "onboard-1" },\n
      })\n
   }\n
end;

 

That patch works with GraphicsEnabler=Yes.


Thanks for all the help. :D
