The Real Time Linux collaborative project was established to help coordinate the efforts around mainlining Preempt RT and ensuring that the maintainers have the ability to continue development work, long-term support and future research of RT. In coordination with the broader community, the workgroup aims to encourage broader adoption of RT, improve testing automation and documentation and better prioritize the development roadmap.
