An Introduction to real-time Linux

Presented by

Edoardo Barbieri, Real-time Kernel Product Manager

About this talk

In 22.04, Canonical announced a beta version of the Ubuntu kernel with the PREEMPT_RT patchset integrated. The new real-time kernel serves extreme latency-dependent use cases and provides deterministic response times to service events. By meeting stringent preemption specifications, real-time is suitable across a broad range of verticals, from telco applications to dedicated devices in industrial automation and robotics. But does a real-time kernel necessarily result in optimized performance? And what would be the consequences of missing a deadline? If you are a Linux kernel enthusiast or just getting started with real-time systems and want to learn more about PREEMPT_RT, this webinar is for you. This webinar will provide a broad overview of the target use cases and real-time applications. Starting with the building blocks, we will learn: - What is a real-time system? - What are the use cases of real-time across market segments? - What is the role of the PREEMPT_RT patchset? - How would one know if a low-latency kernel is acceptable over PREEMPT_RT? And much more. Having set the stage and the necessary context in mind, we will then deep-dive into the Linux kernel build with the out-of-tree PREEMPT_RT patch applied.
