Transferred from: http://www.ibm.com/developerworks/cn/linux/l-cn-kernelmodules/To maintain the stability and sustainability of the Linux kernel, the kernel introduces the feature of loadable modules in the development process. A kernel loadable module is a set of code that can be loaded into the kernel while the kernel is running. Typically, we will fail to load the same module on two different cores, even on two adjacent patch level versions. This i
Getting started writing ZF2 modules
During ZendCon this year, we released 2.0.0beta1 of Zend Framework. the key story in the release is the creation of a new MVC layer, and to sweeten the story, the addition of a modular application architecture.
"Modular? What's that mean? "For ZF2," modular "means that your application is built of one or more" modules ". in a lexicon agreed upon during our IRC meetings, a
First, what is modules?Modules literally means the module, which refers to the kernel modules; Simply put, a module provides a feature such as Isofs, Minix, NFS, LP, and so on. Traditionally, modularity has been solved in two ways: designers can separate functions into a separate process called threading, or recompile the kernel in a way that includes/excludes so
Today the sky just lit up, get up to see Golang 1.11 official release, with two important features: modules and webassembly.

---restore content starts---A Module introduction1. What is a module?#常见的场景: A module is a python file that contains a set of functions, such as spam.py, which is named spam and can be used via import spam. #在python中, the module is used the same way, but in fact, the module can be divided into four general categories: 1. py file 2, written in Python, has been compiled into a shared library or DLL's C or C + + extension 3 folders that organize a series of mod
Article title: Linux solution: Concepts and usage of Modules. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
1. what is modules?
The literal meaning of modules is the module, which refers to the kernel
question: I want to know what modules are built into the kernel in the Linux system and what parameters each module has. Is there a way to get a list of built-in modules and device drivers, along with their detailed information?
The modern Linux kernel is growing rapidly over time to support a large number of hardware, file systems, and network functions. During this time, the introduction of the Loadable
Brief IntroductionThere are seven possible connection modes between general modules, and seven types of coupling are formed. The relationship between them is (independence from strong to weak)
Non-direct coupling (nondirect coupling)If there is no direct relationship between the two modules, the connection between them is entirely achieved through the control and invocation of the main module, which is indi
Why introduce CSS ModulesOr you can say, CSS modules for us to solve what pain point. For the past I write Web style experience, specifically, can be summed up as the following points:Global style conflictsThe process is this: you now have two modules, a, B, you might write your own styles for each of these two modules, such as A.CSS, B.css, and look at the code/

Modules PackagesModule concept: In the development of computer programs, as the program code more written, the code in a file will be more and more long, maintenance is more and more difficult. In order to write maintainable code, we grouped many functions into separate files, and many languages used this organization code, in Python a. py file is called a module.Benefits of using modules: greatly improve

The module is a dynamically loaded component supported by the Linux kernel, and most modules are drivers. And the Linux module is designed to be stacked----is a module running on top of another module, this module may also provide support for the module above, of course, all the modules are running on top of the kernel. As a result, one module may depend on the services provided by another module, or the s
