We will build our custom kernel on top of rCore-Tutorial-v3.
We develop using the Docker environment:
make docker
You should be familiar with:
In this article, we will follow along with Linux Kernel Teaching, progressing from basic to advanced kernel studies, to prepare for potential future kernel development work.
It's worth noting that this course also has a Chinese version, and you can support their efforts by starring the repository at linux-kernel-labs-zh/docs-linux-kernel-labs-zh-cn.
In subsequent blog posts, I may simply summarize the course content, as copying existing material without adding my own insights would be pointless. Our focus will be on the experimental sections.
