Recently in doing the kernel from the small-end processor (arm) to the big-endian processor (PPC) of the work, now kernel into the console stable work, the basic work has been completed, but the transplant has a lot of experience or need to summarize, Today, the kernel is summed up for processing the byte-order of the size-end. Before writing the size-end byte s

Introduction The theme of this chapter is "The design and implementation of Kernel Scheduler", "Kernel scheduling" is the necessary module of all multitasking kernel, the design of scheduling algorithm has a direct impact on the efficiency of the whole system.Examples of this

1. Kernel functions map Low-dimensional space to high-dimensional space The following chart is located in the first to second quadrant. We pay attention to the red door and the purple letters under the words "Beijing courtyard". We think of the dots on the red Door as "+" data, and the dots on the purple letters as "-" data, and their horizontal and vertical coordinates are two characters. Obviously, in this two-dimensional space, the "+" "-" two typ

So here we need to reflect on why

I. Kernel configuration and compilation of the Development Board 1. decompress the kernel package and copy the smdk6410_config Kernel configuration file to. config (default configuration file) to the kernel source code tree. Generally, the platform configuration file is stored in the arch/ARM/configs/directory of the

Kernel Configuration and compilationFirst, kernel cleanupThe first thing we need to do when we get to the kernel is to clean up the kernel and prevent others from configuring the generated intermediate files to affect us:1. config generated by the configuration process.2. Compile the intermediate file (. o) to generate

The previous chapter describes how to compile the Linux kernel. After an image is obtained, it can be burned to the Development Board for running. However, this will also cause some problems: for example, if you want to add or modify some Linux kernel configurations and components, you must re-compile the Linux kernel and then install it on the Development Board.

Phenomenon:CentOS7 boot screen displays multiple kernel optionsReason:Under normal circumstances, there are two startup items, one is "Normal startup" and the other is "Rescue mode Startup" (rescue).If there are more than 2 startup items, the old kernel of the current system is not removed. The reason is that the old kernel is not automatically deleted after the
