Explore advanced techniques for performance analysis on embedded Linux devices in this informative conference talk. Delve into modern sampling and tracing technologies built into the Linux kernel, including perf and LTTng. Learn about Hotspot, an open-source performance analysis tool that visualizes recorded information from perf, enabling offline navigation through vast amounts of sampled data. Discover how to add LTTng tracepoints to userland UI frameworks, using Qt as an example. Gain insights into LTTng's low overhead and future plans for instrumenting Qt within the LTTng tracing ecosystem. Benefit from the speaker's expertise in solving performance issues for automotive customers and working with Embedded Linux platforms.
