Real-time Testing with Fuego - Cyclictest and Ftrace Features

Explore real-time testing techniques for embedded Linux systems in this 27-minute conference talk from the Linux Foundation. Learn about the "cyclictest+ff" test set developed for Fuego, which evaluates real-time performance and identifies causes of response delays. Discover how to customize Fuego for testing various embedded devices and gain insights into practical use cases. Delve into topics such as automated testing, real-time systems, reliability, and fast boot tuning techniques. Examine the implementation of cyclictest+ff, including host-to-host testing, Jenkins integration, and kernel features like Function Tracer. Analyze cyclic graphs, snapshot logs, and testing environments to improve embedded Linux performance. Gain valuable knowledge from Hirotaka Motai, a Head Engineer at Mitsubishi Electric Corp, as he shares his expertise in embedded systems and automated testing.
