Compiling the Linux kernel is the basic function of kernel development, and if we add kernel functionality by directly modifying the Linux kernel code, the modified kernel code must be recompiled to generate a new image file and then load the image file to enable the new

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
