Debian は AMD GPU を使用しません

私はBusterバックポートを介してカーネル5.10を含むDebian 10を実行しています。 amdがインストールしたドライバはamdgpuであり、私が理解したところでは、dmesgドライバが認識されていると出力されます。

しかし、私が実行したりglxinfo -B出力したりDRI_PRIME=1 glxinfo -B する

GPUを使用するプログラムを実行してみましたが、VMWare llvmpipe gpuを使い続けているようで、出力はradeontop常に0％で表示されます。自分のコンピュータでamdgpuを使用するにはどうすればよいですか？
