Learn how to identify and fix timing issues in embedded Linux applications with LTTng and Sourcery Analyzer

Overview

With the increasing complexity of modern embedded systems featuring multi-core hardware architectures and complete general-purpose operating systems such as Linux, the tracer is becoming an ever more useful member of the software engineer's basic tool set. LTTng (Linux Trace Toolkit next generation) is a highly efficient open-source tracer for Linux systems featuring combined kernel and user-space tracing.

This seminar shows a real-world example of how Mentor Embedded Sourcery Analyzer (MESA) can be used to analyze combined user-space and kernel trace data from LTTng to find out why a Linux-based real-time system occasionally doesn't meet its deadline.

What You Will Learn

  • Why and when tracing is useful
  • What LTTng (Linux Trace Toolkit next generation) is
  • How to visualize trace data
  • How to navigate confusing trace data
  • How kernel and user-space trace data can be used together to analyze an application
