"How to make kernel and user space CI for input devices?" - Benjamin Tissoires (LCA 2020)

Making sure that a commit in the kernel doesn't break a mouse, a touchpad or a space bar is hard. Ideally, we need to run this commit, and all versions of it against every possible device. Rinse wash repeat for the user-space commits, because there is this one guy that uses the CPU overheating when long pressing the space bar as an indication to emacs to send a control key event (xkcd 1172).
But the universe hasn't provided us an army of people to test the devices, an infinite amount of resources and a lot of time to spare. So making true CI on actual physical devices is hard. That's a pity, really. Luckily, we have computers, and that's a start.
In this talk we will show how we moved from basically no regression tests 10 years ago to a state where now every commit gets tested against a good amount of various devices. We will show how we can do CI on the kernel side, and how we can do CI on the user space side.
linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
