Description and Notes
This graphics card needs a x1 to x16 powered adapter. The radeon driver for this card requires a kernel recompile, and the card is too old to be compatible with the amdgpu drivers.
So far GitHub user Coreforge has been able to get the card to display terminal output in color, and with a patched memcpy.so library can get GPU acceleration and a window manager loaded, though there are still many small issues.
To get the card working currently, you need to:
- Image Pi OS (the older January 2022 copy built on top of Debian 5.10.x) to your Pi.
- Compile Coreforge’s GPU branch and copy the built kernel to the Pi.
- Install AMD firmware:
sudo apt install -y firmware-amd-graphics - Set up this custom memcpy.so to be preloaded on the system.
- Reboot.
Once that’s done, you should be able to get Xorg working, or just a console. Note that the driver doesn’t seem quite stable yet.
See linked GitHub issue for more details and progress getting the card working.
