Install kernel source code: Installing kernel source code in RedHat or centos, kernel headers install Both centos and rhel5 between des following packages: Kernel-headers: It hosts des the C header files that specify the interface between the Linux kernel and userspace libr

One page The kernel uses the physical page as the basic unit of memory management; the memory management unit (MMU) converts the virtual address to the physical Address, usually in the unit of page processing. MMU manages the tables in the system in the unit of page size. 32-bit system: page size 4 kb 64-bit system: 8 KB page size The kernel uses the corresponding data structure to represent each

I. kernel space The kernel space is mapped by the kernel. It does not change with the process and is fixed. Ii. High-end memory: The physical memory address exceeds MB, which we call high-end memory. 3. kernel space distribution chart (1) The address range of the kernel s

Reverse mobile phone kernel, add debugging support and reverse debugging, and add and debug mobile phone Kernel 0x00 PrefaceAn android application can be debugged only when AndroidManifest is used. the xml display specifies android: debuggable = "true". If the android: debuggable value is not set, the default android: debuggable = "false" is used. Therefore, most published applications cannot be debugged,

Advantages and disadvantages of Linux Device Driver dynamic kernel insertion and direct integration into the Kernel Analysis Introduction: The company made a Linux-based Ethernet interface board, which is currently maintained by me, the main CPU of this Board uses PowerPC, run the Linux system and add two external DPRAM modules. DPRAM is written in the form of a character device driver. It is directly integ

One: The origins of LinuxLinux is an open-source computer operating system kernel. It is a Unix-like operating system written in C and POSIX compliant, and Linux was originally developed by Finnish hacker Linus Torvalds to try to provide free and free Unix-like operating systems on the Intel x86 architecture. The program began in 1991 with the help of some minix hackers in the early stages of the program, and today countless programmers around the wor

To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to start the init process. This process is the first process of the system, PID 1, also known as

Two Problems in upgrading CentOS 6 Kernel to Kernel 3.x Problem: Before the production of openstack CentOS6.5 template image, the kernel is 2.6.xx, now need to make a kernel for 3. x centos6 image, use rpm package kernel-ml-3.18.3-1.el6.elrepo.x86_64.rpm to upgrade the

Difference: the kernel-devel package only contains the kernel header file and makefile required for the kernel development environment, while the kernel-Souce contains all the kernelSource code.If you only want to develop your own modules, you only need to reference the corresponding

I haven't compiled the kernel for a long time. Recently I want to get the driver. I checked that there are two folders under/usr/src, which are empty and do not have any kernel source code.I used centos 5.1. In fact, the Red Hat series did not include the Linux kernel source code after the appearance of redora, so these headers won't be available at the moment wh
