Description and Notes
The Radeon RX 6700 XT (“Navy Flounder”) was released in 2021 and is supported by the open source amdgpu driver in the Linux Kernel, version 5.11 and later. It is also supported by AMD’s Radeon Software for Linux as of the 20.50 version.
It will require a 1x to 16x adapter, or some other means of adapting the 16x-sized card pins into the 1x slot on the CM4 IO Board. You will need to supply 20A of 12V power (about 230W) to the card directly through it’s separate power plugs.
amdgpu (open source) driver
To get the amdgpu driver loaded, you have to recompile the Linux kernel for Pi OS on the 5.11 branch or later.
Device Drivers >
Graphics support on the
menuconfig step, and select the
amdgpu driver to install.
Also make sure you have the AMD firmware installed (
sudo apt install -y firmware-amd-graphics) or the driver will complain about missing files.
If you want to be able to boot the Pi all the way, make sure to blacklist the
amdgpu kernel module:
sudo nano /etc/modprobe.d/blacklist-amdgpu.conf # Put this inside the file and save it: blacklist amdgpu
Now, after a reboot, you can explicitly load the module and see what happens by following
dmesg in another terminal session:
sudo modprobe amdgpu
I haven’t yet run the card on the Pi, so we’ll see what happens then!
See the linked GitHub issue for more details.
