Description
In this talk, Daniel will present two tools provided by rtla. The timerlat tool used to measure IRQ and thread latency for interrupt-driven applications (important for the PREEMPT_RT kernel), and the osnoise tool used to evaluate the ability of Linux to isolate, from the scheduling perspective, a workload from the interferences from the rest of the system. The presentation also includes examples of using the tool to find the root cause of unexpected latencies and how to collect extra tracing information directly from the tool.
