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

Basic Introduction to Linux [Part 4], basic introduction to linux Attributes and permissions of Linux Files And Directories Command: Column 1: inode (index node) index node number, which uniquely identifies a file or directory on a disk, in linux, you must first read the index node of the file (similar to the book dire

How to obtain the Linux kernel source codeHow to obtain the Linux kernel source code To download the Linux kernel, you must go to the official website.

I've always been using Ubuntu and Fedora as a starter system, but actually what I really want to recommend is arch, after the previous study, perhaps you have a general understanding of Linux, and now if you want to speed up your pace, maybe you can look at this article. If you ask why you are learning Linux, I can only answer just for funI've always been using Ubuntu and Fedora as a starter system, but act

1. Use the first Aid disk group for maintenanceThe first Aid disk group (also known as the Boot/root Disk group) is an essential tool for system administrators. 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

Hook Command (Mount)First, introduce the use of the Hook (Mount) command, the Mount command parameters are very many, here is the main point we want to use today.Command format: Mount [-t vfstype] [-O options] Device dirwhich1.-t vfstype Specifies the type of file system, which is not usually specified. Mount automatically selects the correct type. Common types are:Optical or optical Image: iso9660DOS FAT16 file system: MSDOSWindows 9x FAT32 file system: VFATWindows NT NTFS file system: NTFSMoun
