Paper Title: Kernel test automation with kdevops

Paper Abstract: kdevops is an adaptable test automation bringup and test workflow framework which relies on vagrant, terraform, ansible and kconfig. It was written first to provide automation in an abstract way for bringup through local virtualization technologies and abstracting different cloud providers. It has found growth by using kconfig for accepting variability. Among other things, one thing which makes the tests which kdevops tests unique is the low failure rate of some of the tests it uses. And so, to this end, it has adopted a test steady state mechanism for tests frameworks. Accepting low determinism for failures in the Linux kernel is inevitable but not well understood. This talks is aimed at giving an appreciation for low deterministic failures in the Linux kernel with filesystems and the block layer and lessons learned with automation with kdevops. kdevops also pushes us to evaluate if we can establish test baselines for tests for agreed upon test setups for tests which are not highly deterministic, and if sharing results to grow confidence in baselines through collaborative efforts is possible.
