At the recent Linux Kernel Plumbers get-together in Lisbon, Portugal, one of the hottest topics was how to bring better and automated testing to the Linux kernel. There, the top Linux developers united their efforts behind one testing framework: KernelCI.
Now, at Open Source Summit Europe in Lyon, France, to help give KernelCI the resources it needs to be successful, it became a Linux Foundation project.

Until now, when Linux patches were tested, they were done on developers' own machines. That meant you could be sure Linux would run as expected on mainstream hardware. But if your hardware wasn't that popular… Well, chances are it wasn't tested.
As Greg Kroah-Hartman, the maintainer of the Linux stable branch, explained:

"[...] Most people, were just testing on the few things that they cared about. So we want to test it on as much hardware as we could to make sure that we're actually supporting all the hardware that we claim we're supporting."

Put it all together, and KernelCI will improve Linux Long Term Support (LTS) kernel testing and validation; consolidate existing testing initiatives; improve Linux's overall security; and increase the pool of tested hardware. This, in turn, will improve the quality, stability. and long-term maintenance of the Linux kernel. And, that is a very good thing.
