Need Help with DSDT Edit - Radeon HD 6850

Hi,

as i was told in my post installation thread i need to add my ATI card to my dsdt to get all my monitors working.

It currently works with GE=No but no support for Steam Games for example, with GE=Yes everything works fine but only one monitor.

 

Well i wasnt using one so i started all over...

 

System Info:

ASROCK G31M-S R.2

Sapphire Radeon HD 6850 1024MB

 

I tried to do everything myself but get stuck when compiling my DSDT in the end, i tried to follow following tutorial:

http://rampagedev.wordpress.com/2012/07 ... dsdt-36-2/

 

After a bit of reading in i understand the tutorial and did the following steps:

 

1. Extract ioREG to get the Location of my card and found out it was Device (POP2) and checked which Framebuffer is loaded with ioreg | grep ATY (Duckweed)

 

2. Open DSDT Editor and extracted the DSDT of my System

- compiling the extracted and unmodified DSDT works fine

 

3. Edited the DSDT to change to the things mentioned in the tutorial:

 

Found the DEVICE (POP2) under SCOPE_SB/DEVICE PCI0:

Device (P0P2)
           {
               Name (_ADR, 0x00010000)
               Method (_PRW, 0, NotSerialized)
               {
                   Return (GPRW (0x09, 0x04))
               }
               Method (_PRT, 0, NotSerialized)
               {
                   If (PICM)
                   {
                       Return (AR02)
                   }
                   Return (PR02)
               }
           }

 

Changed the Part to the following:

Device (PEGP)
           {
               Name (_ADR, 0x00010000)
               Method (_PRW, 0, NotSerialized)
               {
                   Return (GPRW (0x09, 0x04))
               }
               Method (_PRT, 0, NotSerialized)
               {
                   If (PICM)
                   {
                       Return (AR02)
                   }
                   Return (PR02)
               }
           }         
Device (GFX0)		
               {
                   Name (_ADR, Zero)
                   Name (_SUN, One)
                   Method (_DSM, 4, NotSerialized)
                   {
                       Store (Package (0x0C)
                           {
                               "@0,name", 
                               Buffer (0x0D)
                               {
                                   "ATY,Duckweed"  
                               }, 

                               "@1,name", 
                               Buffer (0x0D)
                               {
                                   "ATY,Duckweed" 
                               }, 

                               "@2,name", 
                               Buffer (0x0D)
                               {
                                   "ATY,Duckweed" 
                               }, 

                               "@3,name", 
                               Buffer (0x0D)
                               {
                                   "ATY,Duckweed" 
                               }, 

                               "model", 
                               Buffer (0x13)
                               {
                                   "AMD Radeon HD 6850" 
                               }, 

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

               Device (HDAU)
               {
                   Name (_ADR, One)
                   Method (_DSM, 4, NotSerialized)
                   {
                       Store (Package (0x02)
                           {
                               "hda-gfx", 
                               Buffer (0x0A)
                               {
                                   "onboard-1"
                               }
                           }, Local0)
                       DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                       Return (Local0)
                   }
               }
           }

 

After that i fixed the Notify Part:

changed "Notify (\_SB.PCI0.POP2, 0×02)" to "Notify (\_SB.PCI0.PEGP, 0×02)"

 

and tried to compile the DSDT, its full of errors and wont compile.

The First error list that Device "DTGP" is not available, then it follows with a load of errors about GFX0 allready in place and what not ;)

Well i then found out that the Device GFX0 was indeed twice in the dsdt, i tried to delete it but with no success and i gues i messed up my dsdt enough to get nowhere with it :-/

 

I hope someone can help me to get this thing to compile, i think the problems may be related to the onboard Intel Card of the Motherboard? I have attached the clean DSDT DSL, the ioreg dump. Anyway thanks in advance!!

Thank you very much, i tried it with the DSDT in place and GE=No but its the same with just GE=Yes. One Display works perfect but not my second monitor.

Well i then tried to connect my second monitor not with the Second DVI Port of the card but with a DisplayPort-DVI Adapter and what do you know... it works!

have now both monitors working fine, but both DVI Ports seems to be a no go...
