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.
