To load the radeon driver, run: sudo modprobe radeonĪfter 10 or 20 seconds, if you have a monitor plugged into the Radeon card, it should come up as the driver loads. After it reboots, you can open up a terminal session and run dmesg -follow to see what's going on (you don't have to, though). # Put the following line inside ld.so.preload: # Create an `ld.so.preload` file to instruct Linux to use our version of `memcpy`. Sudo mv memcpy.so /usr/local/lib/memcpy.so Gcc -shared -fPIC -o memcpy.so memcpy_unaligned.c # Compile the library and move it into place.

We're almost done, but to make Xorg and other compositors like Weston run, you also need to override the memcpy library: # Download Coreforge's modified memcpy library. Then copy the cross-compiled kernel to the Pi. Create a file named /etc/modprobe.d/nf, with the contents: blacklist radeon

To make things easier on yourself, blacklist the radeon driver before copying the cross-compiled kernel to the Pi.

I've been working on a 5.15.y update to that branch, but that version isn't quite working yet, since some of the overridden AMD driver flags we modified were removed between Linux 5.10 and 5.15.

Alternatively, you can clone the raspberrypi/linux source at rpi-5.10.y, and apply Coreforge's branch as a patch file. On a Compute Module 4, the process takes almost an hour.īefore compiling Linux, you need to make sure the branch that's checked out is this branch, from Coreforge's Pi OS Linux fork.

Why cross-compile? Well, a fresh compilation takes between 6-10 minutes on my main workstation. That setup should work on any Mac or Linux workstation. The exact environment and process I follow is thoroughly documented here: Raspberry Pi Linux Cross-compilation Environment. Then I went to my main workstation and cross-compiled the Raspberry Pi kernel.

I put that card in my Raspberry Pi, and installed AMD's firmware with sudo apt install -y firmware-amd-graphics. I downloaded -raspios-bullseye-arm64-full.zip from here and expanded it, then used Raspberry Pi Imager to flash it to a microSD card. The current working patch is based off the previous 5.10.y Linux fork Raspberry Pi maintained, so you need to flash a copy of Raspberry Pi OS from earlier this year (not the latest).

In October 2020, after Raspberry Pi introduced the Compute Module 4, I started out on a journey to get an external graphics card working on the Pi.Īt the time, it'd been over a decade since the last time I'd built a PC, and I had a lot to learn about PCI Express, the state of graphics card drivers in Linux, and PCI Express support on various ARM SoCs.Īfter failing to get the Nvidia GT710 or AMD 5450 running, I started testing the GTX 750 Ti, RX 550, and SM750, all with wildly different architectures and driver support.
