Support of Radeon on Debian

[bronger]

I installed the AMD DKMS kernel module, ROCm, and some graphics stack with

amdgpu-install --usecase=rocm,graphics --gfxversion=auto

on Debian 13 (kernel 6.12) and a gfx1100.

The kernel module did compile, and all packages could be installed without dependency issues. Big thanks to the AMD team and contributors!

But—should it have worked? And if yes, do I have to expect trouble while using it? The situation is confusing to me.

The compatibility matrix of ROCm says that Debian is only supported for the Instinct family. For Radeon (and Ryzen), Debian is not offered.

On the other hand, there is a Debian-native installation of the kernel driver using an Ubuntu Noble APT repository (the same that is used for getting amdgpu-install above). So AMD recommends officially to re-use Ubuntu sources for Debian. (The only dedicated Debian repository is used for ROCm packages for AMD Instinct.)

In an older post, it is said that Radeon is supported on a best-effort basis on Debian, and Debian users are invited to report issues.

So, are my following assumptions correct:

1. ROCm is not officially supported on Debian with Radeon hardware.
2. The kernel driver is subject of the same compatibility matrix as ROCm, meaning that the kernel driver equally has no official support for Debian + Radeon.
3. AMD supports this combination nevertheless on a best-effort basis, meaning that compilation errors and package dependency mismatches are addressed if feasible, missing features are improbable, but nothing is promised.
