Evaluation of Real-time Performance in Embedded Linux - Hiraku Toyooka, Hitachi

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

Linux has already been used in real-time systems. Current mainline Linux supports a variety of real-time features such as deterministic scheduling, kernel preemption, high-resolution timer and IRQ thread. In addition, we can get more deterministic behavior by using PREEMPT_RT patch set. To benefit from those features, we need to pay attention to many kernel configurations, use of appropriate APIs and hardware settings. In this presentation, I will talk about how to enable those real-time features and how to evaluate real-time performance by tools such as rt-tests or by your own program. I will also show measurement results in some ARM Cortex-A boards.
