Mastering Real-Time Linux: PREEMPT-RT and Beyond

From Kernel to Code: Hands-On Real-Time Linux Development with PREEMPT_RT and POSIX Threads

What you’ll learn
Understand the fundamentals of real-time computing and how Linux can be adapted to meet real-time requirements.
Set up, configure, and optimize a Real-Time Linux kernel (with PREEMPT-RT) for deterministic performance.
Develop and debug real-time applications in Linux using threads, scheduling policies, and synchronization mechanisms.
Analyze and measure system latency and jitter using industry-standard tools, and apply best practices to real-world embedded and industrial projects.

Requirements
Basic knowledge of Linux (using the terminal, editing files, running commands).
Familiarity with programming in C or C++ (basic syntax, compiling, debugging).
A computer with Linux installed (Ubuntu, Debian, or similar) — or the ability to set up a virtual machine.

Description
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 LearnThe core concepts of real-time computing and determinismHow PREEMPT_RT transforms the Linux kernel for real-time performanceBuilding and configuring a real-time kernel (e.g., Linux 6.1)Measuring and tuning system latency using tools like cyclictestWriting real-time C/C++ applications with pthread, priorities, and CPU affinityUnderstanding priority inheritance and scheduling policies (SCHED_FIFO, SCHED_RR, SCHED_DEADLINE)Isolating CPUs and optimizing for predictabilityHands-On ExperienceThis course emphasizes practical implementation:Build a real-time kernel from source and apply the PREEMPT_RT patchConfigure boot parameters and CPU isolationImplement real-time applications using POSIX threads Who This Course Is ForEmbedded systems engineers and developersLinux system programmersRobotics and automation developersAnyone interested in low-latency and deterministic systemsRequirementsBasic knowledge of Linux commands and shell scriptingSome C or C++ programming experienceA Linux development environment (e.g., Ubuntu, Debian, or similar)Why Take This CourseLinux 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.

Who this course is for
Embedded systems engineers who want to build reliable, deterministic applications on Linux.
Software developers interested in real-time programming and system-level optimization.
Robotics and automation professionals who need precise timing and low-latency control.
Computer science or electrical engineering students looking to expand their knowledge of operating systems and real-time systems.
Anyone with Linux experience who wants to explore real-time capabilities for industrial, automotive, or IoT projects.
