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] This will make kernel v6.12 the first release to include baked-in real ...
According to Linus Torvalds, "one of the largest kernel releases we've ever had" [21] 6.6 29 October 2023 [1] 6.6.75 [5] December 2026 The new EEVDF process scheduler was merged. It aims to replace the CFS scheduler. Intel Shadow Stack was finally merged; Exploiting ROPs is now harder; Support for Partial SMT
The portability section of the Linux kernel article contains information and references to technical details. Note that further components like a windowing system, or programs like Blender, can be present or absent. Fundamentally any software has to be ported, i.e. specifically adapted, to any kind of hardware it is supposed to be executed on.
The Linux kernel developer and maintainer Greg Kroah-Hartman (GKH) [102] has stated that he uses Arch Linux and that it "works really really well". He has also praised the Arch Wiki , the distribution's rolling release model, and the feedback loop with the community.
The Linux kernel is a free and open source, [11]: 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 startup function startup_32() for the kernel (also called the swapper or process 0) establishes memory management (paging tables and memory paging), detects the type of CPU and any additional functionality such as floating point capabilities, and then switches to non-architecture specific Linux kernel functionality via a call to start ...
Linux kernel boot and decompression process. vmlinux is a statically linked executable file that contains the Linux kernel in one of the object file formats supported by Linux, which includes Executable and Linkable Format (ELF) and Common Object File Format (COFF).
LinuxBoot is a free software project aimed at replacing most of the Driver Execution Environment (DXE) modules in Unified Extensible Firmware Interface (UEFI) firmware with the Linux kernel. LinuxBoot must run on top of hardware initialisation software in order to start. This can be the Pre-EFI Initialization (PEI) part of UEFI, coreboot, or U ...
