If you are a system software developer in fields such as 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.

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!

✅ Junior developer in Linux system software fields including system semiconductors and electric vehicle sectors (autonomous driving, infotainment)

✅ Job seekers who want to work in Linux system software development fields such as system semiconductors and electric vehicles

✅ Graduate school applicants in the field of Linux system software (memory, file systems, operating systems)

✅ Developers from other fields who want to transition their career to Linux system software

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 through version upgrades.After 2024, the Linux kernel version will be upgraded to v6.6 or higher andHowever, the barriers to entry are becoming higher.

Linux system software developers positioned across various fields including system semiconductors and electric vehicles know that they need to understand the Linux kernel well to enhance their development capabilities. However, it's difficult to get a sense of how to learn the Linux kernel and, more importantly, what content they should know well for practical work.

The Core of the Core in Linux Device Driver Development: Interrupt Bottom Half

When entering as a Linux system software developer, most people develop Linux device drivers, and one of the elements that must be implemented and optimized in this process is interrupts. Interrupt bottom halfis essential content that must be understood along with interruptsHere are a few reasons:

  • Most interrupt handlers are used together with interrupt bottom-half techniques.

  • The main issue with peripheral devices controlled through interrupts is identified in the routines related to the interrupt bottom half - along with the interrupt handler.

So in Chapter 6 of my book 'Structure and Principles of the Linux Kernel', I explain the following 'interrupt bottom half techniques'.

  • threaded IRQ (IRQ thread)

  • Softirq

  • Taskrit

I've structured it so that readers can learn interrupt bottom-half techniques through ftrace debugging practice in various ways.

Differentiation Points of the Course

This lecture consists of content that has never been covered on YouTube or any other lecture platform before! We debug the data structures related to Linux kernel interrupt bottom-half techniques and various data structures that make up the Linux kernel (task_struct, thread_info structures) through Linux kernel memory dumps. Students taking this lecture can download an educational program (TRACE32) and practice hands-on.

1. TRACE32 simulator program (educational) and Linux kernel dump provided

Linux system software development extensively uses TRACE32 debugger and related programs. TRACE32 programs require a license to run. If you take this courseEducational TRACE32 simulator program as 'Inflearn course materials'You can download and use the TRACE32 simulator program directly to debug memory dumps. Additionally, you can download and practice with 6 kernel memory dumps that allow you to debug various operations of interrupt bottom-half techniques (threaded IRQ, Softirq).

2. Easy and detailed explanation of the basic concepts of interrupt second-half techniques

When learning the Linux kernel, we analyze kernel source code. However, we encounter many obstacles in the process of analyzing kernel source code. It's difficult to confirm what flow a particular function is called in, and what actual values the data structures of the routines being analyzed have. This lecture dismantles all these obstacles.

We analyze Linux kernel source code related to interrupt bottom-half techniques along with TRACE32 program's call stack and detailed data structures. You can learn interrupt bottom-half techniques much more efficiently than when studying the Linux kernel alone. Additionally, since we analyze ftrace messages extracted from memory dumps, you can understand the operating principles of interrupt bottom-half techniques in detail from a three-dimensional perspective.

3. Introduction to debugging methods used by Linux kernel BSP developers at global system semiconductor companies

Recently, the system semiconductor industry has been emerging. How do Linux kernel system developers at global system semiconductor companies debug Linux kernel drivers?

This lecture covers the following content. We will debug kernel data structures related to processes using the TRACE32 simulator with Linux kernel memory dumps, and analyze key kernel operations by loading memory dumps with crash-utility.

You'll learn this content

Explains the overall flow of interrupt processing and why interrupt bottom-half techniques are necessary.

This introduces the threaded IRQ method, which is widely used as a bottom-half interrupt technique, and explains its core functionality.

Explains the execution flow of the threaded IRQ technique from a big picture perspective and provides detailed explanations of the source code.

This introduces patches related to threaded IRQ and explains how to configure ftrace. It provides detailed explanations of ftrace messages and the execution flow of threaded IRQ techniques.

We will analyze data structures related to the threaded IRQ method in detail using TRACE32 and Crash Utility programs.

This introduces Softirq and explains why you need to understand Softirq well.

This provides a detailed explanation of the types of Softirq services, which are the core of Softirq, and the step-by-step execution flow.

Softirq service request and execution operations are explained in detail through overall execution flow and source code analysis.

Explains the ksoftirqd/[n] kernel thread, which is a daemon that executes Softirq services, and provides a detailed analysis of tasklets.

This explains Softirq-related ftrace tracepoints and provides detailed analysis of ftrace messages.

Educational TRACE32 (Simulator) program and 6 Linux kernel memory dumps provided

In this lecture, we will explain the data structures and call stack that comprise interrupt bottom-half techniques while debugging Linux kernel memory dumps, which is the most advanced debugging method in the Linux system software industry.

It provides advanced debugging methods that can debug 'Linux kernel memory' using debugging programs such as TRACE32 and Crash utility.

✅ You can download the educational TRACE32 program (simulator version) from the course curriculum.Students can debug by loading the kernel memory dump provided in this lecture using the TRACE32 program and following along.

✅ You can directly download the Crash Utility, which is operated as an open source project, to load kernel memory dumps for debugging. By utilizing the various features supported by Crash Utility, you can analyze kernel data structures and call stacks.Direct debuggingYou can do it.

      [CS Technical Interview 2] Operating Systems That Make Sense

      yiyj10305235

      Curated to include only operating system concepts frequently encountered in practice and interviews, this is a core CS (computer-science) lecture, easily explained and organized with a focus on diagrams. It was designed so that even those new to it can grasp the flow and quickly continue their learning. The slides themselves are structured to serve as reviewable summary notes. It's a 'foundational building lecture' that you can return to whenever your fundamentals are shaky.
