spl (short for set priority level, after the PDP-11 assembler instruction of the same name [1]) is the name for a collection of Unix kernel routines or macros used to change the interrupt priority level. [2] [3] This was historically needed to synchronize critical sections of kernel code that should not be interrupted. [4]
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.
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]
The last-used version of Linux libc used the internal name libc.so.5. Following on from this, glibc 2.x on Linux uses the soname libc.so.6 [ 23 ] [ better source needed ] In 2009, Debian and a number of derivatives switched from glibc to the variant [ 25 ] eglibc. [ 26 ]
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
Among Linux kernel developers, the -mm tree refers to a version of the kernel source code maintained by Andrew Morton. The -mm kernel tree used to fill the role of Linux kernel development builds, formerly identified by odd version numbers following "2.6." (see this section [broken anchor] on Linux kernel version numbering). New and ...
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 management ...
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.
