System semiconductors, automotive sector, etc.

System software developers must know the Linux kernel

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 that make up electric vehicles (Automotive), including infotainment, autonomous driving, and telematics.

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.

Linux system software developers and Linux embedded system (BSP) programmers, pay attention!

However, the Linux kernel is like a massive barrier for beginners in the field of system software. Beginners have likely experienced giving up on learning the Linux kernel multiple times. That difficult Linux kernel is becoming increasingly complex as it evolves through version upgrades.After 2024, the Linux kernel version will be upgraded to v6.6 or higherHowever, the barriers to entry are becoming even 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 get a sense of how to learn the Linux kernel and, most importantly, what content they need to know well in practical work.

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

What is the most practical skill that Linux system software developers want to learn? It's debugging skills. Since debugging is proportional to problem-solving ability, they want to develop 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 section 'Debugging and Code Learning', I cover content about debugging.

Differentiation Points of the Course

This course consists of content that has never been covered on YouTube or any other lecture platform before! It covers the latest Linux kernel debugging methods and various case studies. It also introduces methods for debugging kernel data structures through Linux kernel memory dumps. Students taking this course can download the educational program (TRACE32) and practice hands-on.

You'll learn this kind of content

This explains why dump analysis is necessary in real-world projects. It introduces Crash-Utility and TRACE32, which are widely used in real-world projects.

This explains in detail how to debug using Crash-Utility and TRACE32 in real-world projects.

This explains the content of a book about TRACE32 while directly running TRACE32 for debugging. While taking the class, you can download the educational TRACE32 program (educational version: for simulator use)You can practice by following along together.

This explains how to install and run the TRACE32 (educational, simulator) program uploaded to 'Course Materials'. It also provides detailed instructions on how to download the kernel memory dump uploaded to 'Course Materials' and load the kernel memory dump using the TRACE32 program.

This introduces 3 methods for configuring ftrace and provides a detailed explanation of why boot-time ftrace tracer is necessary.

Explains how to configure the boot-time ftrace tracer and provides detailed analysis of related kernel source code.

This introduces how to configure boot command line and provides detailed analysis of related ftrace logs. It covers methods for extracting kernel logs as ftrace logs and techniques for analyzing related messages.

Provides detailed analysis of ftrace messages and explains the related operational principles. Also provides detailed analysis of kernel source code related to initcall.

We will run the Crash Utility program to debug the major data structures of the Linux kernel. We will also analyze the related kernel driver source code together to explain the operating principles in detail.

Explains the detailed operating principles of related functions while debugging Linux kernel dumps with the Crash Utility program.

We introduce various case studies that you can encounter in the process of developing real-world projects. We analyze related kernel logs and the operating principles of the kernel in detail. We also explain how to solve problems through debugging.

This explains case studies of stack corruption and memory leak issues that can be encountered during the development of real-world projects.

This explains the data structures and architecture of the Linux kernel's memory system through Crash Utility debugging.

This explains the main TRACE32 commands (memory address casting) introduced in the book. It provides detailed explanations on how to use related commands directly with the TRACE32 program.

This explains the symbol information of the system call table and uses the TRACE32 command (d.v %y.ll sys_call_table) to check system call handler function information. In the following lectures, we will explain the key commands of TRACE32 along with the core data structures of the Linux kernel.

This provides a detailed explanation of practical commands used in the process of conducting real-world projects (the %l option: outputting register information).

Educational TRACE32 program and 3 Linux kernel memory dumps provided

In this lecture, we will cover the most advanced debugging method in the Linux system software industry -Global top-tier system semiconductor company, Qualcomm Linux kernel developers debugging- Introduces how to debug Linux kernel memory dumps. Provides advanced debugging methods for debugging Linux kernel memory using debugging programs such as TRACE32 and Crash utility.

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

In the domestic system software field, I am the unprecedented author of the 'Linux Kernel' book and 'Arm Architecture (Armv8-A, Armv7-A)' book. 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.
