early bird days left depth


Purpose of the course

This course goes deep into Linux Kernel source code to analyze the memory management in the difficult knowledge : Reverse mapping mechanism .

Most people have an ambiguous grasp of the reverse mapping mechanism , Through the study of this course , We can deeply understand the implementation mechanism of kernel reverse mapping . In the course , Let's start with the basic concepts , Then to the development of reverse mapping , Then go deep into the reverse mapping of three kinds of pages : Anonymous page , File pages and KSM page .

Besides , stay KSM Principle Analysis Chapter , Will be explained in detail through KSM How does this mechanism allow the system to save a lot of memory .

The instructor

Cheetah The teacher has been working in the semiconductor industry , He used to be U-boot Communities and Linux The kernel community has submitted several patches .

Mainly engaged in Linux Related system software development work , be responsible for Soc chip BringUp And system software development , Like reading kernel source code , In constant study and work in-depth understanding of memory management , Process scheduling , file system , Internal nuclear systems such as device drivers .


Total course duration : about 225 minute
