Advanced System Profiling, Tracing and Trace Analysis with Perfetto in Android and Yocto

Together with my colleague Stefan Lengfeld.
Tracing is a capable mechanism for deep system analysis and profiling with a minimal overhead. By recording defined system events, in Linux but also Android, tracing can be used to analyze concurrency or latency issues, for example. Android’s systrace tool made it easy to analyze and correlate traces and events due to a graphical UI, in order to help developers identify performance bottlenecks. The successor to this advanced and convenient tool is called Perfetto. It’s available for pure Linux too, and part of Yocto (meta-oe) since Langdale now. In the talk, we’ll have a look into
- using Perfetto with Android and Yocto,
- adding trace events to your applications,
- recording traces and
- analyzing system and application traces with the graphical GUI.
This will allow you to take full advantage of the Perfetto trace viewer UI for analyzing memory usage, CPU scheduling, latency and more.

Building embedded systems with Yocto on ARM platforms is a common practice, but when the products move further to the edge and become less “embedded,” new challenges arise. In this session, we will explore the requirements and challenges faced when developing Yocto-based systems for edge computing based on Intel.

Organizing My Desk as an Embedded Engineer

As an embedded dev, my desk is always a mess (and I think the ones of my colleagues, too). Working with real hardware leads straight to a number of boards, additional debuggers, tools, cables and more. And of course, as the most developers, I have a number of work projects and another of private ones. Even worse, I’m working from home for a good share of my time, so both kinds contribute to the mess there. Managing this is a constant effort and fight, but rarely successful.

In 2015, we built a sophisticated meeting room information system based on Android Things as a student project. As Android Things was deprecated in 2021, we started to use our Yocto Project experience to develop a maintainable, future proof embedded system.
