[Success] AMD RX6000 Series working in macOS

[etorix]

My windows path is

ACPI(_SB_)#ACPI(PC00)#ACPI(TRP0)#ACPI(PXSX)#PCI(0100)#PCI(0000)#PCI(0000)#PCI(0000)

So I would expect the path to be \SB.PC00.TRP0.PXSX

\_SB.PC00.TRP0.PXSX
Mind the underscore!

That was my forum typo - I wish it were that easy

Have attached my ioreg, gfxutil output and SSDT-BRG0.aml
OpenCore says: ACPI Error: [\_SB_.PC00.TRP0.PXSX] Namespace lookup failure, AE_NOT_FOUND

Have you tried using Corpnewt's SSDTTime script to sort out the missing bridge entries from your GPU's APCI address?

The gfxutil.txt file you provided shows the following:

/PC00/[email protected]/[email protected]/[email protected]/[email protected]/[email protected]/[email protected]

Option #9 in the SSDTTime script should when used with your system DSDT.aml be able to fill out the full APCI path, i.e. translate the pci-bridge entries, so you can use the full address in the SSDT.

Select option 9 - PCI Bridge


Devices BRG1 and Device BRG2 are probably wrong in the SSDT-BRG0.aml table.

Obviously, I wished that too!
Addresses are correct. The ACPI error message look like the first bridge PXSX is not found, although it does have a name. Should we try to define it as well?

Ok so making some progress...

Using SSDTTime's script I have a new BRG0 SSDT. It seems to be recognizing the device but it's now booting to a blank screen. Here's the SSDT generated...

How are you connecting the display to the GPU?

• DP to DP, HDMI to HDMI?
• Are you using any adapters or adapter cables?

Do you have the agdpmod=pikera boot argument in your config.plist?

Have you tried agdpmod=ignore boot argument in place of the pikera argument?

@jkbuha
Does the SSDT-BRG0 by @etorix work?

Thanks for this. I still get the same ACPI Error: [\_SB_.PC00.TRP0] Namespace lookup failure, AE_NOT_FOUND, so it's actually the TRP0 device that's the issue. The SSDTTime-generated SSDT is the only one that works.

So I'm using an eGPU (Razer Core X) connected via thunderbolt cable. The TB mapping is correct: in fact, it works fine with the RX580 which boots up without any need for additional config. agdpmod=pikera/ignore doesn't make a difference at this point...

It defines everything from, and including, TRP0
OK, maybe this is just "the safest, fool-proof, way" to ensure that there's a fully named ACPI path. No error message with this one?

I trust you have the spoofing information as DeviceProperties in config.plist. Is this applied?
