【Issue#1389 動作確認】
□ テスト内容
本Issueの対応で、sysinfo()と/proc/meminfo の下記項目においてMcKernelの情報を
返すようにした。
[sysinfo]
totalram : rusage_global の total_memory
freeram : rusage_global の total_memory - usage_memory
mem_unit : 常に1
[/proc/meminfo]
MemTotal : rusage_global の total_memory
MemFree : rusage_global の total_memory - usage_memory
SwapTotal : 常に0
SwapFree : 常に0
CommitLimit : rusage_global の total_memory - usage_memory
Committed_AS : rusage_global の usage_memory
1. 本Issueで対応したsysinfo() と /proc/meminfo の値が想定どおりとなっていることを確認
McKernelへのメモリ割り当てを 10G@0,10G@1 とした状態で下記プログラムを実行
C1389T01: sysinfo() で取得される値が下記のとおりであることを確認
totalram : 20GiB * 0.95 以上、20GiB 未満であること
freeram : totralram * 0.95 以上、totalram 未満であること
mem_unit : 1 であること
C1389T02: /proc/meminfo から取得される値が下記のとおりであることを確認
MemTotal : 20GiB * 0.95 以上、20GiB 未満であること
MemFree : MemTotal * 0.95 以上、MemTotal 未満であること
SwapTotal : 0 であること
SwapFree : 0 であること
CommitLimit : MemFreeと同値であること
Committed_AS : MemTotal - MemFree と同値であること
2. 本Issueで対応したsysinfo() の項目を利用する以下のLTPを実行し、PASSすることを確認
- mtest01 -p80
- mtest01 -p80 -w
- mem01
□ 実行手順
$ make test
McKernelのインストール先や、OSTEST, LTPの配置場所は、
$HOME/.mck_test_config を参照している
.mck_test_config 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
□ 実行結果
x86_64_result.log aarch64_result.log 参照。
すべての項目をPASSしていることを確認。
