[Rikoshet]

Ok here is your original plist.

check this plist out.

Finaly have some days to proceed with my testings. I tried your suggestions but t's even worse, please take a look at 2 screenshots. Doing your way is not injecting values...

The AMD drivers do not contain the device ID for the S7100X FirePro card (0x10026929). The AMD9000Controller.kext/Contents/info.plist shows the following:

You need to add the device ID to the AMD kexts for the FirePro to work in macOS. Depending on which version of macOS you are running will dictate how this is to be achieved. If it is possible, what with the new security Apple have added to their newest OS's.

You may need to use a related device-id against the S7100X's Device Properties in Clover or OpenCore to fake the card so it works in macOS. You already have the IOReg and Device Path addresses for the card, as they are shown in the first screenshot above.

This page over at TechPowerUP shows the other Amethyst GPU's with your R9 M390X and some Mac cards in the mix - https://www.techpowerup.com/gpu-specs/amd-amethyst.g778

Can you point me to a guide, please? I mean, the right way to do that with opencore. Thank you!

I tried that way:

And now I an see it again under System Information but it's not usable still, and device ID is not the one I'm trying to inject:

You are using String instead of Data for device ID.
Try device-id data <29690000>
Try using SSDT-BRG0.aml this helps Open Core to set device ID.

It seams to inject the device-id now but no kext attached. We are closer now but mising something.... Any idea?

It is not correct. The config.plist may be corrupted or has conflicting device IDs.

I'm sorry, can you explain why you think so? As you suggested I injected 0x6929 dev-id and you can see it in IOReg.

The device ID is not working, it should read <2969000> in the IOReg. Look at the IOReg picture I posted the device-id and ATYdevice-id are symbols and not numbers.
Try this SSDT it has PEGP added.

Still nothing with new ssdt.



But how can yo uexplain the fact that under System nformation the device-id is the injected one?

Make a copy of your config as is and then try removing the #AAPLSlot, and ATY entries.
Is the PCI at the top correct path?
