Configuration Menu Language (CML) was used, in Linux kernel versions prior to 2.5.45, to configure the values that determine the composition and exact functionality of the kernel. Many possible variations in kernel functionality can exist; and customization is possible, for instance for the specifications of the exact hardware it will run on.
The GNU C Library is a wrapper around the Linux kernel system call interface. A C standard library for Linux includes wrappers around the system calls of the Linux kernel; the combination of the Linux kernel system call interface and a C standard library is what builds the Linux API. Some popular implementations of the C standard library are
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.
Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
The interface between the perf utility and the kernel consists of only one syscall and is done via a file descriptor and a mapped memory region. [6] Unlike LTTng or older versions of oprofile, no service daemons are needed, as most functionality is integrated into the kernel. The perf utility dumps raw data from the mapped buffer to disk when ...
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 until next stable version; Long-term support (LTS); maintained for a few years [1]
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
