AMD APUs (Radeon 780M/760M/740M and similar integrated graphics) do not
benefit from the full ROCm compute stack in LXC containers. ROCm is a
multi-GB GPGPU framework primarily designed for discrete AMD GPUs and
ML/AI workloads, not for video transcoding with integrated graphics.
For APUs the Mesa VA-API drivers (mesa-va-drivers, mesa-opencl-icd) and
firmware (firmware-amd-graphics) provide all the hardware acceleration
needed for media tasks. Installing ROCm on top adds ~4GB of packages
that frequently fail or time out for this class of hardware.
Discrete AMD GPUs (GPU_TYPE=AMD) are unaffected and still receive ROCm.
