Explore debugging methodologies for real-time issues in Linux systems through this 49-minute conference talk by Joel Fernandes from Amazon. Dive into common scenarios causing latency problems in embedded Linux systems and learn to use Linux-based latency tracing and deep system tracing tools. Discover instrumentation techniques and dynamic probing methods for problem detection, and understand how to interpret scheduler statistics to identify processes suffering from higher latencies. Gain insights into preemption, RT Patch, Kernel Off Tracer, and hardware issues affecting real-time performance. Learn about cyclic tests and latency tracking to improve the responsiveness of embedded Linux systems.
