Now I can analyze the Linux kernel too! The easiest kernel lecture among Linux kernel lectures.

This is Part 1 of a roadmap lecture that concisely organizes the essential computer science (CS knowledge) needed to excel in development and data, in a short period. This lecture has also been used as an in-house lecture at top domestic companies for several years. Based on 20 years of experience in actual practice, from system SW to web, app development, and data science, this lecture systematically yet easily organizes the essential core knowledge needed to excel in development and data.

The author of "Learning the Structure and Principles of the Linux Kernel through Debugging" properly explains the core interrupt concepts of the latest Linux kernel (v6.1), most used in system software.

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.

The author of 'Linux Kernel Structure and Principles Learned Through Debugging' properly explains the core concept of the 'interrupt bottom half' in the latest Linux kernel (v6.1), most used in system software.
