A hundred blog series. This is: the v08. Xx HongMeng kernel source code analysis (total directory) | millions of Chinese character annotation The blog analysis
Intensive reading of the kernel source code
Four code stores synchronous annotation kernel source code, >> view the Gitee repository
Analysis of 100 blogs. Dig deep into the core
Add comments to hongmeng kernel source code process, sort out the following article. Content based on the source code, often in life scene analogy as much as possible into the kernel knowledge of a scene, with a pictorial sense, easy to understand memory. It’s important to speak in a way that others can understand! The 100 blogs are by no means a bunch of ridiculously difficult concepts being put forward by Baidu. That’s not interesting. More hope to make the kernel become lifelike, feel more intimate. It’s hard, it’s hard, but there’s no turning back. 😛 and code bugs need to be constantly debug, there will be many mistakes and omissions in the article and annotation content, please forgive, but will be repeatedly amended, continuous update. Xx represents the number of modifications, refined, concise and comprehensive, and strive to create high-quality content.
