kselftest is one of the main test suites that comes with the Linux kernel source tree itself. As such, it is an obvious one to cover by KernelCI. For each kernel revision built by KernelCI, an extra build is produced for each CPU architecture with a kselftest config fragment merged on top of the main defconfig. The resulting kernel and kselftest binaries are then stored together and used together, to guarantee compatibility between the tests and the kernel.

The aim is to run all of kselftest, whenever applicable. Only a subset of all the available test collections are currently being run while infrastructure is getting prepared for gradually expanding coverage to the full set.
The table below shows a summary of the current KernelCI kselftest coverage per
CPU architecture and platform for each collection. Until a more dynamic
orchestration becomes available, this is all defined in
The goal is to have each kselftest collection run on at least 2 platforms of
each CPU architecture. All these tests are typically run on every kernel
revision built by KernelCI, except for those that aren’t present in older
