Website. kernel .org. The Linux kernel is a free and open-source, [12] : 4 UNIX-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
The system call interface of a kernel is the set of all implemented and available system calls in a kernel. In the Linux kernel, various subsystems, such as the Direct Rendering Manager (DRM), define their own system calls, all of which are part of the system call interface. Various issues with the organization of the Linux kernel system calls ...
An oversimplification of how a kernel connects application software to the hardware of a computer. The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes.
GPL and LGPL. Namespaces are a feature of the Linux kernel that partition kernel resources such that one set of processes sees one set of resources, while another set of processes sees a different set of resources. The feature works by having the same namespace for a set of resources and processes, but those namespaces refer to distinct resources.
This article documents the version history of the Linux kernel . Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support: Supported till next stable version. Long-term support (LTS); maintained for a few years [1]
The major contemporary general-purpose kernels are shown in comparison. Only an overview of the technical features is detailed. section below). Linux (kernel), Android, Ubuntu, CentOS, webOS, Fire OS, Firefox OS, ChromeOS, Syllable Server, Mastodon Linux, OpenBSD/Linux, Plan 9/Linux, Sailfish OS, Tizen, amongst others.
The Linux Programming Interface is a well-regarded [3] work on Linux systems programming and is available for readers in several languages. [4] The Linux kernel API to userspace discussed in the book consists of both the System Call Interface and the GNU C Library. In-kernel APIs are not discussed in the book, neither are ABIs.
Kernel build. Kernel build is the process of compiling and configuring the Linux kernel source code to generate a functional kernel image that can be loaded into memory and executed by the operating system. [1] The kernel serves as the core component of the Linux operating system, providing essential functions such as process management, memory ...
