Mm Tree
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 on Linux kernel version numbering). New and experimental code used to find its way into a 2.6.x-mm kernel build. Historically, the -mm tree focused on new developments for the memory management part of the kernel (mm). Occasionally, the -mm tree was overloaded with new patches, so testing it became difficult. On September 17, 2007, Morton sent a mail saying that "this just isn't working any more". The presence of the new linux-next git repository has offloaded much of the work that made mm maintenance troublesome, allowing Morton to continue to use quilt A quilt is a multi-layered textile, traditionally composed of two or more layers of fabric or fiber. Commonly three layers are used with a filler mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Kernel
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), 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 software, free replacement for Unix. Since the late 1990s, it has been included in many Linux distributions, operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android (operating system), Android which is used in many mobile and embedded devices. Most of the kernel code is written in C (programming language), C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly language, assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a Modular programming, modular design such that modules can be inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

Andrew Morton (computer Programmer)
Andrew Keith Paul Morton (born 1959) is an Australian software engineer. He is one of the lead developers of the Linux kernel, and a co-maintainer of the Ext3 file system, the journaling layer for block devices (JBD) and memory management. Biography In the late 1980s, he was one of the partners of a company in Sydney, Australia that produced a kit computer called the Applix 1616, as well as a hardware engineer for the now-defunct Australian gaming equipment manufacturer Keno Computer Systems. He holds an honours degree in electrical engineering from the University of New South Wales in Australia. Morton maintains a Linux kernel patchset known as the ''mm'' tree, which contains work-in-progress patches that might later be accepted into the official Linux tree maintained by Linus Torvalds. "mm" as a primary testing ground became unmanageably large and busy, and in 2008 the "linux-next" tree was created to fill much of this role. In 2001, Morton and his family moved from Wollon ...

Quilt (software)
Quilt is a software utility for managing a series of changes to the source code of any computer program. Such changes are often referred to as " patches" or "patch sets". Quilt can take an arbitrary number of patches as input and condense them into a single patch. In doing so, Quilt makes it easier for many programmers to test and evaluate the different changes amongst patches before they are permanently applied to the source code. Tools of this type are very important for distributed software development, in which many programmers collaborate to test and build a single large codebase. For example, quilt is heavily used by the maintainers of the Linux kernel. Quilt evolved from a set of patch-management scripts originally written by Linux kernel developer Andrew Morton, and was developed by Andreas Grünbacher for maintaining Linux kernel customizations for SuSE Linux. It is now being developed as a community effort, hosted at the GNU Savannah project repository and distribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
