![]() These types of tests stress the kernel in unique ways, exposing problems that might otherwise go unnoticed from release to release. ![]() The support for the Chromium OS userspace is the start of full-stack tests in KernelCI. It is still quite experimental, but the support will evolve over the next few months, opening the path for other product-specific userspaces. Increased kernel testing diversity will definitely result in catching more regressions earlier. On another front, there was progress enabling more testing for different kernel areas as well as improvements to the rootfs testing images used by KernelCI: “Keeping upstream healthy is really important to us in the Chrome OS team (and Google broadly!) since we constantly pull in stable fixes and regularly push out major kernel version upgrades to our users.” said Jesse Barnes who leads the Base OS team of Chrome OS at Google. kselftests received new tests for the futex() system call, basic semantics validation, and soft-dirty page table entry mechanism corner cases.improved LTP crypto tests by enabling missing kernel configs needed.libcamera now has its first few tests running on KernelCI.fs/unicode tests converted to the new Kunit mechanism.bootr test to check if all CPUs went online successfully.experimental support for including firmware files in the rootfs.The overall results were significant for only a few days of work. ![]() Kernel testing through product-specific userspace opens a whole new avenue of possibilities for KernelCI. On top of that, there was an accomplishment for many test cases and test suites, as detailed above. We’ve achieved a lot in such a short time, in spite of a few workflow weaknesses which we’re now addressing to help further grow the KernelCI community with new developers.” said Guillaume Tucker, KernelCI project lead and Senior Software Engineer at Collabora. ![]() More hackfests will come in the future – this was only the first one. Dates are being discussed for the next hackfest to happen around the end of August, a few weeks before the Linux Plumbers Conference. The KernelCI team invites developers and companies to participate. ![]()
