(Kthreadd, NULL, CLONE_FS | Clone_files); Click (here) to collapse or open Creates a Kthreadd kernel thread that manages and dispatches other kernel threads. It loops through a function called Kthreadd, which is the function of running the kernel thread maintained in the Kthread_create_list global list. Call Kthread_create to create a k

in the dictionary there are two main definitions, one is "soft, a nut edible part", for Linux kernel, of course, the second definition: "The core part of something." So broadly speaking, Linux kernel is the most central part of the Linux operating system, and in the narrow

calls this middle layer to prevent users from operating hardware devices abnormally. c. The user processes run in virtual spaces as separate entities, this is also the reason for providing such an interface between the system and the user process. It is the same as installing multiple virtual machines on a hardware. the posix api, POSIX, and C library POSIX are a set of General API Interface Standard C libraries that implement the call process of most API user States stipulated by POSIX: applic

transmits fd to the upper layer. The upper layer uses a select or epoll to listen to this descriptor. The underlying layer writes the message to this file every time there is a message, then use a flag to notify the upper layer ,?After the upper layer detects the file, it reads the file according to the mutually defined structure. In this way, a communication can be completed. Netlink and 8 are asynchronous notifications. Generally, they are suitable for sending data from the underlying layer t

systems allow most or all of the functionsProcessAll of them run in the kernel, so that you can directly call the function to eliminate frequent context switches. The following are typical examples of the micro-kernel. Linux is a single kernel, but it draws on the essence of the micro

the future development trend. However, because a single mode (in most cases) runs well in Linux, and kernel porting is relatively difficult, it does not obviously impede the work of the programmers, they have enthusiastically transplanted the kernel to most of the existing real systems, not to mention some seemingly u

Http://www.ibm.com/developerworks/cn/linux/l-kdb/index.htmlThis article will first introduce some kernel code monitoring and error tracing techniques on the Linux kernel, which vary depending on the required usage environment and usage methods, and then focus on the source-level debugging methods of the three

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

Introduction to the Linux kernel module the overall structure of the Linux kernel is already very large, and it contains many components. How can we include all the required parts in the kernel?One way is to compile all required functions into the

feel it.Android, however, is still stable in the beta version of the Linux kernel for years.Why did the android team choose linux? Maybe because the development board they bought at the time only supports linux....... The following is a joke:1.

mkinitrd depends on the package device-mapper, device-mapper depends on lvm2. Therefore, you need to download lvm2, device-mapper, and mkinitrd.:Http://down1.chinaunix.net/distfiles/LVM2.2.02.51.tgzHttp://down1.chinaunix.net/distfiles/device-mapper.1.02.28.tgzHttp://down1.chinaunix.net/distfiles/mkinitrd-4.2.0.3.tar.bz2Their installation is similar to installing module-init-tools. 2. kernel-related operationsDownload KernelClick the Version Download

One, why to learn the kernel? Some people have to learn the kernel, while others can not learn it. If you want to engage in system development or drive development in the future, you should learn the kernel. Just contact the kernel
