Peter Zijlstra, Red Hat

Workshop on Operating Systems Platforms for Embedded Real-Time applications (OSPERT 2008)
Prague, Czech Republic, July 1 2008

---

Summary

This talk will be about the linux-rt project, its history, current state and future. It will cover the design decisions we made and highlight some of the practical techniques like run-time lock validation and latency tracers that helped us to quickly spot and fix problems. It will touch upon some of the recent developments in linux-rt such as rwlocks with full priority inheritance support and adaptive spins for mutexes as well as talk about some of the work that is currently in progress. The talk will also focus on current and future challenges and how academic real-time researchers can help solving those and by doing so bring our two communities closer together.
