[Success] AMD RX6000 Series working in macOS

[etorix]

PCIROOT(A0)#PCI(0000)#PCI(0000)#PCI(0000)#PCI(0000)
ACPI(_SB_)#ACPI(PC01)#ACPI(BR1A)#ACPI(PEGP)#PCI(0000)#(PCI0000)

Why isn't in windows nothing related to SL01?

Glxutil ACPI data in macOS
/PC01@0/BR1A@0/SL01@0/pci-bridge@0/GFX0@0 = PciRoot(0x1)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

Are both the same? I'll keep reading the whole thread. Page 7 now

Are both outputs from using the same card? If the PCI bridge is in the card and not onboard, the path may be different between Radeon VII and RX 6950XT.

No everything is in the DSDT. See attached.

I read here that if:

the name ends at 0xFFFF it can be enumerated to anything therefore it has to be disabled:
Name (_SB.PC01.BR1A.SL01._STA, Zero)

No. I cannot boot in macos with the radeon 6950 xt, so took out, put back my radeon vii. used the glxutil that you see in mac os. I quit the radeon vii and put back the 6950xt, tried new SSDT with the Bridge modificatiom Zirkaiva did but no joy.

Today I extracted in windows the acpi data but with the 6950xt.

But the pci slot is the same for both gpu cards.

Name (_SB.PC01.BR1A.SL01._STA, Zero)

So should edit the SSDT and try that? Damn I have master now and have family duties after, I shall try tomorrow.

thanks both for you helo.
have a nice day

Hmmm… This is an old guide about attaching NVidia drivers, written for Clover and not making use of WhateverGreen. I would ignore it for now, and not involve SL01 in any SSDT; PEGP is the right device.

Windows ACPI data from Device Manager:

PCIROOT(A0)#PCI(0000)#PCI(0000)#PCI(0000)#PCI(0000)
ACPI(_SB_)#ACPI(PC01)#ACPI(BR1A)#ACPI(PEGP)#PCI(0000)#(PCI0000)

/PC01@0/BR1A@0/SL01@0/pci-bridge@0/GFX0@0 = PciRoot(0x1)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

Same chain of addresses, unmatched ACPI names.
Try using this SSDT instead. ('BRG1' instead of 'BRG0' to avoid confusion with previous versions… The 'Zero' address is what matters, the name given to the bridge is irrelevant.)

I got my BRG0 working only after disabling SL05 as in the old guide.
If the above code does not work, try this:

DefinitionBlock ("", "SSDT", 2, "ACDT", "BRG0", 0x00000000)
{
    External (_SB_.PC01.BR1A.PEGP, DeviceObj)
    External (_SB_.PC01.BR1A.SL01, DeviceObj)

    Scope (\_SB.PC01.BR1A.PEGP)
    {
        Device (BRG1)
        {
            Name (_ADR, Zero)  // _ADR: Address
            Device (GFX0)
            {
                Name (_ADR, Zero)  // _ADR: Address
            }
        }
    }
    Name (_SB.PC01.BR1A.SL01._STA, Zero)
}

Try this one. No device properties injection needed.

Oh man I came home so wasted last night, I have just woke with so much headache …

Your SSDT works mate, first try boom … Where do I send the spanish jam?
thank you so much and thanks Etorix too.

this community is awesome
