Ubuntu 20.04 に対応したという ROCm 3.7 がリリースされたため、Linux Mint 20 にインストールしてみました。
詳細は公式ドキュメントを参照いただくとして、ROCm の OpenCL 部分だけをインストールしたいので、以下のパッケージをインストールしました。
apt install rock-dkms rocm-opencl rocm-opencl-dev rocminfo
インストール後に PC を再起動し、rocminfo で結果を確認してみると、以下のように大成功です。
$ /opt/rocm-3.7.0/bin/rocminfo
ROCk module is loaded
Able to open /dev/kfd read-write

しかし、続けて clinfo でインストール結果を確認してみると、残念な感じです。

gfx803 の Radeon RX 570 を認識して欲しいのですが、Number of Devices 0 でした。
いろいろと調べてみると、/etc/OpenCL/venders/amdocl64_30700.icd に定義されている libamdocl64.so を見つけられていないのではないかと思い、/etc/ld.so.conf.d/rocm-opencl.conf というファイルを作成し、そこに以下のような内容を定義してみました。
/opt/rocm-3.7.0/opencl/lib定義後、以下のコマンドで反映させます。
ldconfig
反映結果の確認はこちらのコマンドで、成功したようです。
ldconfig -p | grep -i opencl
しかし、これでも clinfo の結果は変わらず、もう少し調べてみたところ、ncurses5 というパッケージが足りないのでは、という情報を見つけました。ROCm 3.7 よりも古いバージョンでの情報です。
古いバージョンの情報ですが、試しにやってみます。
apt install libncurses5
なんと、ncurses5を追加インストール後に clinfo は成功しました！！
