Debugging Real-Time Linux Scheduling Latency with rtla timerlat

Explore the intricacies of debugging real-time Linux scheduling latency in this 50-minute conference talk by Daniel Bristot de Oliveira from Red Hat. Delve into the growing importance of this skill as more projects, particularly in automotive and industrial applications, rely on Linux. Learn about the limitations of traditional black box testing methods and discover the powerful capabilities of rtla (real-time Linux analysis), a kernel tool designed to simplify debugging of real-time kernel features. Focus on rtla timerlat, which offers comprehensive functionality for measuring latency, tracing causative factors, producing standardized auto-analysis, and breaking down scheduling latency issues into manageable components. Gain insights into the tool's user-friendly interface, the details of the timerlat tracer, and the auto-analysis output. Witness a demonstration of effective strategies for tackling complex scheduling latency problems using this innovative approach.
