Feedback form is now closed.
Marek is doing day-to-day testing of the Linux kernel 'next' branch since 2018. Since v4.15 Linux kernel release there are almost 250 commits with his 'Tested-by' and 90 commits with his 'Reported-by' tags. In his speech, Marek will present his system used for the daily tests, show how does it work and what kind of tests are being performed. Then he will show how he identifies the regressions, how to prepare a report about such regression and how to help kernel developers to fix it. Marek will also show how a typical bisection process does look like, how to do it automatically and how to interpret the results. He will also share some practical hints and tips related to the process of finding regressions and identifying broken commits. In the summary Marek will briefly compare his solution with other kernel testing robots and systems.
