Explore real-time scheduling fault simulation techniques in Linux through this conference talk by Ben Dooks from Codethink. Delve into methods for simulating faults such as jitter, deadline misses, and other issues in real-time systems. Learn about the importance of fault injection for testing application and system resilience, particularly in safety-critical environments. Discover various approaches for fault injection in both user and kernel space, including the use of existing kernel features and potential extensions. Compare different methods and their relative merits for testing scheduler behavior and real-time scheduling in Linux. Gain insights into improving the testing and reliability of real-time systems, with a focus on error handling and mitigation strategies like throttling, restarting, and controlled shutdown of services.
