hello I don't know how to change the graphics card identifier
amd r9 390

 

[Edhawk]

You need to create a custom SSDT-GPU-SPOOF.aml table for your R9 390. Using the R9 390X card as the basis for the spoof (fake ID).

Follow this guide:

Renaming GPUs (SSDT-GPU-SPOOF) | Getting Started With ACPI

The guide uses your GPU as the target/example card, so it should be fairly straightforward. Once you confirm the ACPI address of your GPU.

 

[laurent]

I've never done that
dois-je supprimer les phrases en vert dans l'exemple ssdt ?

I don't understand anything more after you have to compile it and put it in efi

 

[Edhawk]

1. Have you created the SSDT?
   • Have you used the correct ACPI Address for your systems GPU?
   • This can be obtained from the Hackintool > PCIe tab or from IORegistryExplorer in macOS.
2. If yes, post a copy so we can see what you have created.
3. Have you added a companion entry to your /EFI/OC/config.plist for the SSDT?
   • The SSDT won't work without the config.plist entry.

bonjour quand je veux compiler il y a des erreurs

What does your System show when you look at the BIOS Device Name (Nom du périphérique BIOS) under Device Manager in Windows?

This is what I see when I look at the BIOS device name for my RX580 on an Intel system.

Bios device name

This is what is shown for the same card under Location Paths.

Location paths (Chemins d’accès)

They are both showing the same information, but the Bios device name is easier to understand and use when editing the SSDT.

As you might have guessed I am not using macOS at present so I can't check why maciasl is throwing up those four errors.

Nom de l'appareil bios

 

[Edhawk]

The errors were caused by incorrectly added '/' before the' _SB' part of the device path.

I have edited the SSDT and attached both a .dsl and .aml version so you can see what I changed to remove the compilation errors.

Hope the revised SSDT works.

hello
thank you very much i will compare and include that in the efi folder and in the config.plist
Thanks for your help
I will test this

 

[laurent]

hello
the gpu is well recognized but there is a graphics acceleration problem
maybe in the boot flag
do you have an idea ?
I'm going to try -radvesa

 

[laurent]

-radvesa does not work
-raddvi does not work

 

[Edhawk]

-radvesa wouldn't work, as it forces the GPU to use basic VESA mode. The opposite of what you are trying to accomplish.
-raddvi is used to enable DVI transmitter correction, if the DVI connector is not working correctly.

Try -radcodec and radpg=15

-radcodec Allows non-supported cards to use HW video encoder, to force the spoofed PID to be used in AMDRadeonVADriver
radpg=15 Fixes HD 7730/7750/7770/R7 250/R7 250X initialisation

 

[laurent]

Thanks I will try that

 

[laurent]

sorry it's me again
I tried the boot flags but nothing different
but I saw that there was no metal support
I don't know if it's configurable?

Is acceleration working?

 

[laurent]

no it does not work when I want to put a window in the background I click on the orange button I wait 15 seconds for it to run
the launchpad too

hello I solved the graphic problem by replacing whatevergreen with a version earlier than 1.4.1
and everything works perfectly thank you for your help which made me progress

No need to do that, just add a no-gfx-spoof property with value 01.
