When I read the embedded Linux LED driver today
The driver implementation part is clear.
But the paths of several header files really confuse me. the Linux 2.6.13 file is organized as follows:
The header file is as follows:
#include
But I cannot find the ASM folder corresponding to the arm, or the corresponding directory does not correspond to the s3c24xx folder.
Later, I accidentally read an article a

Linux Process Scheduling analysis and linux scheduling AnalysisOverview
Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an absolute saying, just as many people say that "a function is XX times more efficient than a function", it is out of the actual environment, these conclusions are o
displayed and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the image is loaded, the second stage of the bootloader gives control to the kernel image and the kernel can decompress and initialize it. During this phase, the second stage of the bootloader detects the system hardware, enumerates the system-linked hardware devices, mounts the root device, and then loads the necessary kernel modules. After

It allows you to start and run a complete Linux system independently. In fact, there is a complete Linux system on the 2nd disk of the first aid disk group, including the root file system, while the 1th disk holds the bootable kernel. It is easy to

I agree with the BSD Protocol and FreeBSD's responsible development team model, so that I like FB. Of course, OpenBSD is also good. However, for performance and Chinese support, FB is more suitable for desktop.
But an indisputable fact is that with the support of many commercial co
