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.
Go to 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.
On the Compute Module 4, to avoid the whole system from locking up on boot, 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
On the Compute Module 4, nobody has been able to get the amdgpu drivers to get far in their initialization stages. The Pi crashes due to PCIe bus memory allocation/mapping errors.
On the Pi 5, the system doesn’t crash, but I get an error *ERROR* hw_init of IP block <psp> failed -22.
See the linked GitHub issue for more details.
