GoKawiilRedox OS team completes io_uring-style ring buffer support for system services
The Redox operating system project has finished a grant-funded phase of work implementing ring buffer communication at the system task level, modeled on Linux's io_uring. The team built an io_uring/liburing-like API for applications, ring buffer machinery for system services and drivers, supporting async executor crates, and performance improvements to speed switching between applications and services.
GoKawiil's interpretation of the reporting above, not reported fact.
Faster, lower-overhead communication between applications and system services could make Redox more competitive with Linux for I/O-heavy workloads, since io_uring has become a performance-critical interface in the Linux ecosystem. The work was funded by NLnet, NGI Zero Commons, and Horizon Europe, and Ron Williams notes NLnet is opening new funding rounds, which may support further Redox development.
- Redox completed a grant-funded project adding io_uring-like ring buffer support at the system task level.
- An application-facing API mimicking io_uring/liburing was built alongside an async executor for drivers.
- NLnet is opening new grant funds (Restack, Code Supply) with a November 3, 2026 application deadline.
