PREEMPT_RT was a set of patches for the Linux kernel which implement both hard and soft real-time computing capabilities. [1] On September 20, 2024, PREEMPT_RT was fully merged and enabled in mainline Linux on the supported architectures x86, x86_64, RISC-V and ARM64. [2]
A pull request, a.k.a. merge request, is a request by a user to merge a branch into another branch. [118] [119] Git does not itself provide for pull requests, but it is a common feature of git cloud services. The underlying function of a pull request is no different than that of an administrator of a repository pulling changes from another ...
cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, etc. [1]) of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers". [2]
In former times, the memory controller was part of the chipset on the motherboard and not on the CPU-die. Although the support of a specific instruction set is the task of the compiler, the software must be written with a certain level of abstraction in mind to make this portability possible.
The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch–execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.
git pull fetches remote changes into the local clone, and merges them into the current working files. git checkout replaces the current working files with files from a branch. git checkout --track creates a local branch from a remote branch, links them, and replaces the current working files with files from that branch. git fetch
This process is called fuzzy patch application, and results in a kind of asymmetric three-way merge, where the changes in the patch are discarded if the patch program cannot find a place in which to apply them. Like CVS started as a set of scripts on diff3, GNU arch started as a set of scripts on patch. However, fuzzy patch application is a ...
A software build is the process of converting source code files into standalone software artifact(s) that can be run on a computer, or the result of doing so. [1]In software production, builds optimize software for performance and distribution, packaging into formats such as '.exe'; '.deb'; '.apk'.
