Building Hard Real-Time Linux Systems with Xenomai
Talkat LinuxCon @ Open Source Summit Japan 2023 · on Tuesday, 2023-12-05· at 17:30· Conference Room 1 (3F Level), Ariake Central Tower Hall + Conference, 3-7-18, Ariake, Koto-ku·
summary
Claims that Xenomai's co‑kernel still beats PREEMPT_RT for some mission‑critical use cases and that Xenomai 3 vs Xenomai 4 (EVL) tradeoffs matter, with concrete tools and flows: duft tail patches and ipipe split interrupts, the Cobalt core plus userland libs, kernel support for multiple LTS versions, and a Dockerized mini Debian image for quick testing. Deployed examples include motion controllers, MRI control units and film motion rigs and low‑latency audio; project is 20 years old, China users dominate recent meetups, and benchmarks are situational rather than definitive.
