オープンソースドライバーをインストールしました この質問への回答で説明したとおり また、AMDアプリSDK 3.0をダウンロードしてインストールしました。 テストコードdevices.cおよびhello.c コンパイルして実行しますが、OpenCL 1.1 MESAのシンボリックリンクをlibOpenCL.soに置き換えた後でも、すべてが/usr/lib/x86_64-linux-gnu/を報告しますSDKからのもの：

質問： デバイスが実際にOpenCL 1.2をサポートしていないかどうか、または サポートが存在する場合、それを有効にしますか？どうもありがとうございました！
追伸ディスクリートカード用のドライバーはインストールしていませんが、必要ないと言われています。埋め込みカードでXを実行しています：
$ glxinfo | grep -i vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
Vendor: Intel Open Source Technology Center (0x8086)
OpenGL vendor string: Intel Open Source Technology Center
P.S.2。 opencl-headersおよびmesa-opencl-icdをアンインストールすると、/opt/AMDAPPSDK-3.0/bin/x86_64/clinfoでも動作しなくなりました（プラットフォームIDを取得できません）。
Edit3：前のものを修正しました、へのリンクを作成することにより
Sudo ln -s '/opt/AMDAPPSDK-3.0/lib/x86_64/sdk/libamdocl64.so' /usr/lib/x86_64-linux-gnu/libamdocl64.so
が、CPUをOpenCLデバイスとして報告するようになりました！

編集4：試した このバージョン Ubuntu 16.04上のOpenCL用fglrxドライバ、clinfoがクラッシュするだけです。
編集5：このアプローチをカスタムDebian 8 jessie LiveCDで動作させ、OpenCL 1.2 GPU（fglrx-driver + AMD APP SDKがVMのchrootにインストールされていることを報告しました（fglrxがハードウェアの検出に失敗したにもかかわらずXorgを更新しますが、DKMSモジュールがインストールされ、オンラインガイドに従ってLive USBにパックされました）、Ubuntu 14.04で同じことを達成できませんでした（Debianは必要なプログラムでサポートされていません）。私の16.04と古いUbuntuの両方の問題は次のようです：
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series] (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel driver in use: radeon
Kernel modules: radeon
いいえ、環境変数DRI_PRIME=1を設定することで、fglrxを作成してAMDを現在のレンダラー（14.04）として表示できますが、clinfoはそこでクラッシュします。
fglrxは非推奨であり、新しいAMDドライバーはRadeon xxxxMをサポートしていませんが、オープンソースのradeonはOpenCLをサポートしていません。
A10-7850k APUで私の問題を部分的に解決しました。私が走った：
Sudo ln -s '/opt/AMDAPPSDK-3.0/lib/x86_64/sdk/libamdocl64.so' /usr/lib/x86_64-linux-gnu/libamdocl64.so
しかし、今ではCPUはopenCL 1.2上にありますが、GPUは1.1上にあります。 GPUは、opencl 1.1を使用してlibclcでコンパイルされたamdgpuオープンソースドライバを使用しているようです。グラフィックスドライバーにAMD libの使用を強制する方法がわかりません...ここにclinfoの出力を示します。
