2024/07/30/Tue 15:35 I listened to the lecture well. Thank you for explaining debugging well. I didn't listen to the debugging lecture, but I listened to other lectures first, and I wondered what the logs I was analyzing would look like, but I learned that it's better to listen to the lectures in order, just like the roadmap you gave me. I learned that I can analyze the Linux kernel well through debugging while listening to the lecture. Thank you always for creating good lectures.

What you will gain after the course

Why debugging is important in real-world projects and the actual debugging process
Methods to improve debugging skills and issue types in real-world projects

System semiconductors, automotive sector, etc.

Linux Kernel That System Software Developers Must Know

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

The core of the Linux operating system is the Linux kernel. Along with the Armv8-A architecture, Linux kernel knowledge can be considered the most essential foundational knowledge required in the current system software industry.

However, the Linux kernel is like a massive barrier for beginners in the field of system software. Beginners likely have experienced giving up on learning the Linux kernel multiple times. That difficult Linux kernel is becoming increasingly complex as it evolves with version upgrades.After 2024, the Linux kernel version will be upgraded to v6.6 or higherHowever, the barriers to entry are becoming higher.

Linux system software developers positioned in various fields including system semiconductors and electric vehicles know that they need to understand the Linux kernel well to develop their capabilities. However, it's difficult to grasp how to learn the Linux kernel and, more importantly, what content they need to know well in practical work.

2. Difficulty getting help with debugging

How do you debug Linux system software-related projects? Most of the time, you analyze kernel logs or memory dumps. What abilities are required to properly analyze logs or dumps? You need the ability to read and understand Linux kernel source code or grasp the operating principles of processes and interrupts. However, in real projects, senior developers with these abilities are rare, and even if you're lucky enough to have a developer who is good at debugging, most are too busy to provide detailed and kind explanations.

3. It's difficult to understand why debugging is done

Regardless of the field, most people know that debugging is a core competency for developing problem-solving skills. However, many job seekers as well as junior Linux system software developers often don't understand why debugging is necessary in real-world projects. They also feel frustrated because it's difficult to know what they need to prepare to become good at debugging. Moreover, when they are assigned bugs or issues during real-world projects, they are likely to repeat trial and error because they don't even know how to start analyzing. This eventually leads to endless overtime work, and they end up blaming themselves for lacking aptitude in the Linux system software field.

What development capabilities do Linux system software developers most want to cultivate?

So what is the practical skill that Linux system software developers want to learn most? It's debugging skills. Since debugging is proportional to problem-solving ability, they want to improve their debugging capabilities. While there are many blogs and materials about the Linux kernel, they rarely cover how to systematically solve problems using the latest debugging techniques.

So in Chapter 3 of my book 'Learning Linux Kernel Structure and Principles through Debugging', in the 'Debugging and Code Learning' section, I cover content about debugging.This lecture is a direct lecture by the author of 'Linux Kernel Structure and Principles Learned Through Debugging' and covers the content of Chapter 3 of the book.Additionally, it explains practical debugging methods not covered in books.

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

In the domestic system software field, I am the author who wrote the unprecedented! 'Linux Kernel' book and 'Arm Architecture (Armv8-A, Armv7-A)' book. I am also a current 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.
