Hello,
The aim of this series is to make resctrl_tests run by using kselftest framework. - I modify resctrl_test Makefile and kselftest Makefile, to enable build/run resctrl_tests by using kselftest framework. Of course, users can also build/run resctrl_tests without using framework as before. - I change the default limited time for resctrl_tests to 120 seconds, to ensure the resctrl_tests finish in limited time on different environments. - When resctrl file system is not supported by environment or resctrl_tests is not run as root, return skip code of kselftest framework. - If resctrl_tests does not finish in limited time, terminate it as same as executing ctrl+c that kills parent process and child process.
Difference from v2: - I reworte changelog of this patch series. - I added how to use framework to run resctrl to README. [PATCH v3 2/5] - License has no dependencies on this patch series, I separated from it this patch series to another patch. https://lore.kernel.org/lkml/20211213100154.180599-1-tan.shaopeng@jp.fujitsu...
With regard to the limited time, I think 120s is not a problem since some tests have a longer timeout (e.g. net test is 300s). Please let me know if this is wrong.
Thanks,
