Debugging Real-Time Linux Scheduling Latency with rtla timerlat - Mentorship Session

Explore the intricacies of debugging real-time Linux scheduling latency in this comprehensive mentorship session led by Daniel Bristot de Oliveira, Senior Principal Software Engineer at Red Hat. Delve into the growing importance of this skill as Linux becomes increasingly prevalent in automotive and industrial applications. Learn about the limitations of traditional black box testing methods and discover how the rtla (real-time Linux analysis) kernel tool revolutionizes debugging for real-time kernel features. Focus on the rtla timerlat tool, which simplifies scheduling latency debugging by integrating measurements with kernel tracing features. Gain insights into the tool's functionality, including latency measurement, tracing of key factors, standardized auto-analysis, and breakdown of scheduling latency issues. Examine the timerlat tracer in detail and understand how to interpret the tool's auto-analysis output. Witness a demonstration of effective strategies for tackling complex scheduling latency problems, equipping yourself with valuable skills for optimizing real-time Linux systems.
