Build Real-Time Systems with Linux — from Kernel Fundamentals to Deterministic Applications.

This course takes you on a practical journey through Real-Time Linux using the PREEMPT_RT patch, giving you the knowledge and tools to transform a standard Linux kernel into a low-latency, predictable, real-time platform.

Whether you’re developing for industrial automation, robotics, aerospace, or embedded systems, this course will help you understand how Linux achieves determinism — and how to design applications that meet strict timing constraints.

  What You’ll Learn

• The core concepts of real-time computing and determinism
• How PREEMPT_RT transforms the Linux kernel for real-time performance
• Building and configuring a real-time kernel (e.g., Linux 6.1)
• Measuring and tuning system latency using tools like cyclictest
• Writing real-time C/C++ applications with pthread, priorities, and CPU affinity
• Understanding priority inheritance and scheduling policies (SCHED_FIFO, SCHED_RR, SCHED_DEADLINE)
• Isolating CPUs and optimizing for predictability

  Hands-On Experience

  This course emphasizes practical implementation:

• Build a real-time kernel from source and apply the PREEMPT_RT patch
• Configure boot parameters and CPU isolation
• Implement real-time applications using POSIX threads

  Who This Course Is For

• Embedded systems engineers and developers
• Linux system programmers
• Robotics and automation developers
• Anyone interested in low-latency and deterministic systems

  Requirements

• Basic knowledge of Linux commands and shell scripting
• Some C or C++ programming experience
• A Linux development environment (e.g., Ubuntu, Debian, or similar)

  Why Take This Course

Linux is everywhere, but standard Linux is not deterministic. 
By understanding how to configure and program a real-time Linux system, you’ll unlock the ability to build responsive, reliable, and time-critical software for any industry.
