Roadmap Guide 🎯

This lecture is a roadmap'Linux kernel - basic course for system software developers'is included in the course.

If you're a system software developer in fields like system semiconductors and automotive

Essential Linux Kernel Knowledge

What is the most widely used operating system across all IT devices? It's the Linux operating system. It is used in smartphones, digital TVs, aviation entertainment systems, and servers. System semiconductor companies utilize Linux (Linux device drivers) to control the hardware they design. Additionally, Linux is extensively used in various components of electric vehicles (Automotive) such as infotainment, autonomous driving, and telematics.

In the current AI era, various AI applications also run on Linux servers.

The core of the Linux operating system is the Linux kernel. Along with the Armv8-A architecture, the Linux kernel can be considered the content that requires the most essential foundational knowledge currently needed in the system software industry.

Not only system software developers but also

Linux kernel that developers from various fields should also understand well

However, knowledge of the Linux kernel is necessary not only for system software developers but also for those in other fields - backend developers, server management developers, DevOps engineers, and security developers.

• Backend Developer / DevOps Engineer: Understanding the structure and functions of the kernel is helpful for managing system performance and stability in server operations, cloud, and container environments.

• Security Researcher / Reverse Engineer: When analyzing system vulnerabilities or researching malicious code and attacks, you need to understand kernel internal operations, memory structures, and the principles of system calls.

However, the features that make up the Linux kernel are vast, and it's often overwhelming to know what content you should learn for actual work in the field. Additionally, there are more and more people who need to quickly grasp the core concepts of the Linux operating system before they can start development.

Additionally, the Linux kernel is like a barrier for those encountering it for the first time. Beginners likely have experience giving up on learning the Linux kernel multiple times. That difficult Linux kernel is evolving to become increasingly complex as versions are upgraded.After 2024, the Linux kernel version will be upgraded to v6.6 or higher, the barriers to entry are becoming even higher.

For developers who are experiencing such difficulties, I, the author of 'Learning Linux Kernel Structure and Principles through Debugging', have created this Linux Kernel Overview course.

Attention System Software Developers, Backend Developers, and DevOps Engineers!

The prospects of Linux and the key functions of the Linux kernel, explained in an easy-to-understand way by the author of 'Learning Linux Kernel Structure and Principles Through Debugging'!

The author of 'Learning Linux Kernel Structure and Principles Through Debugging' (2021 Korea Academy Award for Outstanding Books) introduces the prospects and components of the latest Linux kernel. By taking this lecture, you will be able to understand the learning direction of the Linux kernel and identify which content among the vast Linux kernel functions you should master well.

Based on book writing/teaching experience
Deeper and more detailed than anyone else!

I am the author who wrote the unprecedented! 'Linux Kernel' book and 'Arm Architecture (Armv8-A, Armv7-A)' book in the domestic system software field. I am also a current industry developer who knows the latest system software trends (electric vehicles, system semiconductors - system software) best, and an educator who is most actively engaged in knowledge dissemination activities in the system software field.

• 'Learning Linux Kernel Structure and Principles Through Debugging' (2021 Korea Academy Outstanding Book Award) Author

• Author of 'Structure and Principles of Arm Architecture for System Software Development' (2024 Korea Academy Outstanding Book Award)

• 'Programmers Dev Course: Linux System and Kernel Expert' Main Instructor

• June 2022, Korea Computer Congress (KCC2022) - Tutorial Presentation [Conquering the Linux Kernel Using ftrace]

• LG Electronics 'Linux Kernel' and 'Armv8 Architecture' In-house Instructor (including domestic and overseas developers) - (2020~2024)

I can confidently say that I am an educator who can explain the major functions that make up the Linux kernel better than anyone else in Korea.

You'll learn this kind of content

Explains the overall structure of the Linux operating system and provides a detailed explanation of why it's important to learn the Linux kernel well.

This explains the ecosystem related to the latest Linux system software development. It covers in detail why you need to understand the Linux kernel in the process of developing electric vehicles and system semiconductors.

Introduces the content that makes up each chapter and summarizes and explains the key points.

The explanation supplements content that couldn't be covered in the book. Additionally, it analyzes the execution flow based on the latest Arm architecture, the 64-bit Armv8.

This course explains the major concepts that make up the Linux kernel while analyzing the latest version (v6.1) Linux kernel source code.

This course provides a detailed introduction to the kernel's key features while analyzing ftrace messages extracted based on the latest Linux kernel version (v6.1).

This course explains the key data structures and flow of the kernel while debugging using "kernel memory dump," the latest debugging method. It uses the TRACE32 simulator and Crash Utility that can be directly applied to real-world projects.
