The Linux Kernel Functional Testing (LKFT) project is aiming at improving the quality of the Linux kernel by performing functional testing on Arm hardware.

LKFT has built over 1 millions kernel per years other the last two years and ran 140 millions tests on both emulation (qemu) and hardware devices.

In this talk I will present the current architecture that is able to build and test millions of kernels with a really small team of engineers and at a reasonable cost.

LAVA is an automated validation architecture primarily aimed at testing deployments of systems based around the Linux kernel on ARM devices, specifically ARMv7 and later. LAVA is becoming the de facto standard to test software (bootloader, kernel, userspace) on development boards (rpi, juno, beagle, ...). It's used by many projects to build large testing systems like kernelci.

Testing a testing system like LAVA is sometimes a tricky task. In order to test LAVA we had to develop some specific tools (meta-lava, DummySYS, lavafed, ...) that I will present during this talk.

LAVA is at the same time supporting a wide range of devices and maintained by a small team of people. Which mean that maintainers do not have access to most device types that LAVA is supported.

In this lightning talk, I will present LAVA Federation, a project aiming at testing the LAVA software on community owned hardware. The tests will be spread across many labs, owned by the community members with a variety of community hardware.
