Hi, Here is a blog post related to detecting and understanding high interrupt-processing latencies on real-time systems. It is based on a new project called latency_tracker that hooks on the existing kernel tracepoints and executes actions when high latency events occur.
https://lttng.org/blog/2016/01/06/monitoring-realtime-latencies/ It is a work in progress, so if you are interested and/or have any comments, please let me know.
