Linux Kernel Functional Testing, or How to Build and Test Millions of Linux Kernels
summary
Linaro’s LKFT builds and tests Linux at cloud scale: it compiles 1.6 million kernels yearly and runs 200 million Linux and 580 million Android tests per year, delivering full RC reports within 48 hours. The pipeline uses containerized reproducible cross‑toolchains (TXM), parallel VM testing with QEMU/FVP via TXRun, dynamic AWS provisioning, physical board automation with LAVA, a caching layer (Kiss) and a Squad datalake to store results, all operated by a three‑person team.
