How to install official AMDGPU linux driver with kernel 4.19.x on Stretch and Buster
This page recommends potentially unsafe practices
This page documents non-recommended practices such as installing packages meant for other GNU/Linux distributions and manually patching files provided by packages.
My system is made of an AMD Athlon 200GE with Radeon Vega Graphics CPU/APU on a B450M motherboard (Asus PRIME B450M-A). This APU uses the amdgpu driver provided by the linux kernel.
Although I upgraded to linux 4.19 on stretch, the system freezes during boot-up and until now the only way to make it boot was either to use kernel >= 4.20 or use the "nomodeset" kernel parameter.
However it is possible to make that system boot with the AMDGPU driver provided by AMD on a linux kernel 4.19 (which is currently backported on Stretch and also the linux kernel version of Buster).
I guess that could help also those having a AMD Ryzen 2200G (or any AMD Raven Ridge APU) if they face a similar issue, or anyone who may want to have a more up-to-date amdgpu driver.
It tested this with the following versions of amdgpu : v19.10, v19.20 & v19.30.
- For version 19.10 and 19.20 it was necessary to apply patches to allow compilation on kernel 4.19,
- but with 19.30 patching is not needed any more.
Steps in brief (detailed procedure below)
- Get the linux driver from amd's website
Install amdgpu-dkms & amdgpu-core packages
Skip this step if you use version 19.30 (it now builds without patching). But if you still want to use 19.10 or 19.20 you will have to apply a patch to the amdgpu-dkms source so that it does compile with linux 4.19 on debian.
- Reconfigure amdgpu-dkms
Reboot & it's done
- From what I observed, DKMS compiles for both the running kernel and for the highest kernel version installed. It is unlikely compilation will work with my patch applied on something else than v4.19, so you should remove the linux-headers-* packages of the other versions installed. This used to be true for v19.10, but may not be true anymore with 19.30. I didn't give it a try with 19.30.
In case your system freezes at boot with 4.19, add the "nomodeset" kernel parameter at boottime into grub (or by amending /etc/default/grub ). Once in 4.19 you can proceed with DKMS compilation with the steps bellow
What you need/Prerequistes
- AMD's linux driver (take the package for Ubuntu 18.04.x)
Latest version (doesn't need patching) : Radeon™ Software for Linux® 19.30 (Release Date: August 12th 2019)
- Older versions (needs manual patching) :
- A debian system running stretch or buster with kernel 4.19.x
linux-headers-<version>-amd64 package has to be installed so that you can compile the admgpu driver
apt-get install linux-headers-<version>-amd64
ONLY for version 19.10 & 19.20 : my patch to AMD's amdgpu-dkms source code so that it can compile on 4.19.x. Apply the patch corresponding to the version of amdgpu driver you want to use
This procedure is detailed for version 19.30, please adapt it for version 19.10 or 19.20 if you prefer to use that one.
Extract the archive downloaded from AMD
~$ tar -xvf amdgpu-pro-19.30-855429-ubuntu-18.04.tar.xz
Install only these 2 packages : amdgpu-dkms & amdgpu-core. This will fail at the end because it cannot compile on 4.19 without applying my patch.
~# dpkg -i amdgpu-core_19.30-855429_all.deb amdgpu-dkms_19.30-855429_all.deb
Skip this step if you use version 19.30. Do this ONLY if you want to use 19.10 or 19.20 : Apply the patch to the amdgpu source code (please adapt yourself for 19.20)
~# cd /usr/src/amdgpu-19.10-785425
~# patch -p1 < 01-amdgpu_19.10_on_linux_4.19-v4.patch
Skip this step if you use version 19.30. Do this ONLY if you want to use 19.10 or 19.20 : Reconfigure the amdgpu-dkms package so that it does compile against 4.19
~# dpkg-reconfigure --force amdgpu-dkms
Normally, building & installation should have succeeded
Check which version is loaded during boot (for me with amdgpu 19.30 it says "version: 5.0.73")
~# dmesg | grep "amdgpu version"
If you are on stretch I strongly suggest you upgrade to the latest mesa, libdrm, libglvnd, wayland packages from stretch-backports. I'm not sure this is actually mandatory, but on my system the packages from these source are in their stretch-backports versions:
- mesa 18.2.8
- libdrm 2.4.95
- libglvnd 1.1.0
- wayland 1.16.0
- All this has been done on:
Stretch 9.9 with kernel 4.19 & packages described above
- Buster 10.0 as of 2019-Jun-11
- With version : amdgpu-pro-19.10-785425 (released by AMD in Apr/2019)
amdgpu-dkms provides the firmwares inside the deb package (/usr/src/amdgpu-19.10-785425/firmware/). They will be installed in the /lib/firmware/$(uname -r) directory during its installation. During firmware loading, the kernel will search first in /lib/firmware/$(uname -r) and only then, if not found, in /lib/firmware/ (see kernel code or debian kernel code), so the firmware from amdgpu-dkms has priority over the one provided by debian package firmware-amd-graphics which puts the files in /lib/firmware/.
- Recommends installing upstream proprietary packages compiled for Ubuntu
- These are the DKMS packages containing the source of amdgpu driver which is then compiled toward the current kernel installed on debian.
- Instructs user to patch files provided by packages
- Fixed: No more patching is needed with 19.30, but I kept them anyway in case someone needs the older version
