Debugging Methodologies for Realtime Issues in Linux Systems - Joel Fernandes, Amazon

Sign up or log in to save this to your schedule and see who's attending!

This session will walk the audience through some common scenarios where latencies hit an embedded linux system causing loss of real-time performance that the embedded system expects. I will share experiences using Linux based latency tracing and deep system tracing tools and show how to use them. I will also share some methodologies such as instrumentation techniques and dynamic probing to detect problems. Lastly we will go through scheduler statistics which may indicate processes in a system that are suffering from higher latencies and how to use them.
