I think the learning method mentioned by the author is worth looking. The following is what I wrote: Almost every beginner of the operating system kernel will feel difficult to get started. This is because the kernel involves a wide range of knowledge and requires learners to master a large amount of knowledge, including program compilation, links, loading details, operating system theory, and computer syst

I upgraded Ubuntu14.04 to the latest 4.0.5 kernel version. I didn't plan to record it, But I encountered some problems during the upgrade, So I recorded it, share it with yuanyou who have encountered the same problem. Go to the official website to download the latest kernel compressed package: https://www.kernel.org/speed, just use the thunder in the virtual machine to download it, and then try again. LZ co

Preface In the last few months, I have made a rough research on Linux kernel. Next I need to perform in-depth and detailed analysis. It mainly uses a Development Board of S3C2440 as the hardware entity. It includes the following content: 1 bootloader analysis, mainly uboot, combined with the specific situation of the Development Board. My goal is to explain how uboot works (to be honest, I don't want to be kidnapped by hardware during the analysis, bu

To compile the linux module on the X86 platform, the original operating system is not equipped with the kernel source code. Therefore, the kernel cannot be compiled, and the kernel module cannot be tested. According to a lot of information, I decided to upgrade the linux kernel version. The upgrade is successful. The m

1./proc DirectoryThe Linux kernel provides a mechanism for accessing kernel internal data structures and changing kernel settings at run time through the/proc file system. The proc file system is a pseudo-file system that only exists in memory and does not occupy external memory space. It provides an interface for accessing system

ObjectiveIn recent months, the Linux kernel has probably been studied, the following need to conduct in-depth specific analysis. The main development Board of S3C2440 is a hardware entity. It probably contains such things as the following:1 bootloader analysis, to Uboot-based, combined with detailed development of the board. My goal is to explain clearly how uboot works (to be honest, the analysis does not want to be kidnapped by hardware, but it need

One, the Linux kernel compared to the traditional Unix kernel comparison:(1): Linux supports dynamic kernel modules. Although the Linux kernel is also a monolithic structure, it allows dynamic removal (rmmod xxx) and loading of kernel modules (Insmod Xxx.ko) when needed.(2):

Source: http://www.top-e.org/jiaoshi/class/ Generally, users do not need to care about the specific location of a section. In the user State, the kernel will parse the sections of the elf executable file and map it to the virtual address space. However, when the kernel is started, everything starts from scratch. Many applications in user mode do not need to worry about things. For example, the task of sect
