LIS25-111 The Importance of Linux Kernel Functional Testing (LKFT)

• Wednesday, 14 May 11:00 - 11:25
• Room: Session room 2 | Opala I & II

## Abstract: The Linux kernel runs on devices from phones to supercomputers. Frequent updates and new Arm hardware make it essential to ensure that changes do not break anything in Arm Ecosystem. This is where Linux Kernel Functional Testing (LKFT) plays a key role. LKFT is testing project that checks if the Linux kernel works properly across different arm and arm64 platforms. It builds and runs tests to detect issues, ensure stability, and support long-term kernel versions. This talk explains how LKFT works, why it is important, and how it helps developers catch issues early. We will explore LKFT’s testing tools, such as kselftest, LTP, KUnit, and kvm-unit-tests, and how they verify different parts of the kernel. The talk will also highlight recent improvements, including ARMv9 and virtualization on the Graviton4 Baremetal and Graviton4 VM. By sharing real examples of how LKFT finds and fixes problems, this session will show why developers, testers, and system engineers should use LKFT to improve Linux reliability across Arm Ecosystem. ## Key takeaways - Why Linux kernel testing is important - How LKFT keeps the kernel stable - The tools used in LKFT testing - How LKFT benefits developers and users in Arm world
