The Linux tracing infrastructure provides several methods for recording events in the operating system. Apart from many other use cases, tracing is often being used to identify the root cause of high latencies on Linux with enabled real-time configuration. The possibility of filtering and a fine granular selection of the events to be recorded reduces the overhead and therefor allows tracing of time critical sections with low impact on the runtime behavior. Events generated by the tracing infrastructure can also serve as a hook for eBPF programs, which run in a sandbox inside the kernel. These can be used for timing analysis within the kernel without the need of switching to userspace. This presentation will give a brief overview of the Linux tracing infrastructure, eBPF and how they can be used to analyze scheduling latencies on a Linux system with real-time requirements.
