arm64版UTIテストセットREADME
(1) テストの実行方法
事前準備
1. arm64版syscall_interceptライブラリを用意する
https://github.com/RIKEN-SysSoft/syscall_intercept.git
2. McKernelはENABLE_UTI=ONでビルドしたものを用意する
以下の手順でテストを実行する
1. $HOME/.mck_test_configを用意する
当該ファイルは、McKernelをビルドした際に生成されるmck_test_config.sample
ファイルを$HOMEにコピーし、適宜編集する
2. 必要に応じて、LD_LIBRARY_PATH環境変数を設定する
3. make testを実行する
(2) テスト項目詳細
CT12-CT20
test/uti/READMEを参照のこと
(3) 実行結果ログ
result.logファイル内に実行時のログを記載する
実行に利用したIHK/McKernelは、以下のものである
