Steering Xenomai into the Real-Time Linux Future
summary
Xenomai commits to a smaller, maintainable core, keeps co-kernel semantics for legacy real-time code and plans an overhaul that aims for upstream relevancy. Work includes an i‑pipe patch queue to simplify out‑of‑tree maintenance, a new dovetail interrupt routing plus steely co‑kernel core implementation, CI/test hosting and a policy to track one LTS (4.4 for now). Project has few active maintainers, lost a key maintainer recently, supports real products (MRI, PLCs, printers) and is usable but needs contributors to stay viable.
