Learn about simulating real-time scheduling faults in Linux systems through this technical talk that explores methods for testing application resilience to timing issues. Discover approaches for injecting faults like jitter and deadline misses to validate error handling mechanisms, particularly important for safety-critical systems. Examine both user-space and kernel-space fault injection techniques, including how to leverage and potentially extend existing kernel features. Compare different testing methodologies and their relative advantages for verifying scheduler behavior and real-time performance. Gain insights into implementing robust testing strategies for processes dependent on real-time scheduling, including validation of mitigation responses like throttling, service restarts, and controlled shutdowns.
