Open Source C Operating System Kernels for Linux

Tools and patches for the Linux Diskquota system as part of the Linux kernel

The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.

Project's goal is to create better tools for diagnosing Linux systems. Diagnostics include first failure data capture, error log analysis, preventative testing, and system inventory gathering. You can now find Power System specific packages on github. libservicelog : https://github.com/power-ras/libservicelog servicelog : https://github.com/power-ras/servicelog lsvpd : https://github.com/power-ras/lsvpd libvpd : https://github.com/power-ras/libvpd ppc64-diag : https://github.com/power-ras/ppc64-diag sysfsutils is moved to github. New home for sysfsutils : https://github.com/linux-ras/sysfsutils

Squashfs is a highly compressed read-only filesystem for Linux. Squashfs compresses both files, inodes and directories, and supports block sizes up to 1Mbytes for greater compression. It is implemented as a kernel module under VFS.

CachyOS - Arch Linux Based Distribution With Heavy Optimizations & Multi-Architectures For Ultimate Desktop Experience Filesystems: - btrfs - zfs - ext4 - xfs - f2fs Our installer will auto detect which micro architecture your machine got, if x86-64-v3 or x86-64-v4 is detected it will automatically use the optimized packages, which is around a 10 % performance improvement. Desktop Environments: - KDE - CuteFish - i3 - Gnome - Openbox - Wayfire - Xfce - LXQT - bspwm All packages are compiled with Full LTO and other optimization flags. Depending on the march your cpu have it is compiled against x86-64, x86-64-v3 or x86-64-v4. For the Desktop Environment we provide basic theming. In CachyOS-Hello can be also security related packages enabled, like: DNScrypt-proxy Firejail apparmor Security and Performance! https://discord.gg/qJqj94uFwE https://t.me/+zCzPX4cAFjk1MTY

This project is a random collection of Linux kernel-related projects and source code.

Linux Test Project (LTP) is a joint project started by SGI, OSDL and Bull developed and maintained by SUSE, Red Hat, Fujitsu, IBM, Cisco, Oracle and others. The project goal is to deliver tests to the open source community that validate reliability, robustness, and stability of the Linux Kernel. The testing suites contain a collection of tools for testing the Linux kernel and related features. Our goal is to improve the Linux kernel and system libraries by bringing test automation.

lmbench is a suite of simple, portable, ANSI/C microbenchmarks for UNIX/POSIX. In general, it measures two key features: latency and bandwidth. lmbench is intended to give system developers insight into basic costs of key operations.

QP real-time embedded frameworks (RTEFs) provide lightweight, modern event-driven architecture based on active objects (actors) and hierarchical state machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal single-chip microcontrollers, completely replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4F/M7) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and desktop OSes, such as Linux and Windows.

The WSL2-Linux-Kernel repo contains the kernel source code and configuration files for the WSL2 kernel. If you discover an issue relating to WSL or the WSL2 kernel, please report it on the WSL GitHub project. It is not possible to report issues on the WSL2-Linux-Kernel project. Instructions for building an x86_64 WSL2 kernel with an Ubuntu distribution are provided. The number one way that we recommend you run Linux distributions is by installing Windows Terminal. Using Windows Terminal enables you to open multiple tabs or window panes to display and quickly switch between multiple Linux distributions or other command lines (PowerShell, Command Prompt, PowerShell, Azure CLI, etc). You can fully customize your terminal with unique color schemes, font styles, sizes, background images, and custom keyboard shortcuts.

RichARCH is designed to be a Simple Quick Pure path to Arch Linux with kickstart like automation features. One goal of the project is to only use packages in the basic Arch Linux repos by default with the option to install a few non-standard packages (like Pamac, Spotify, and Warp Terminal). Our hope is that this will help to make Arch Linux more approachable to individual and corporate users. Make sure to backup any data you wish to keep from the storage device you plan to use with the RichARCH installer. Details and installation info can be found at: https://download.sf.net/richarch/InstallAndInfo.pdf - or - https://sites.google.com/view/richarch Supports: - AMD / Nvidia drivers - Fully automated installs - LVM storage setup options - Multiple storage formats, including: BTRFS, EXT4, XFS Desktop Environments: - Budgie - Cinnamon - Cosmic - Enlightenment - Gnome - Hyprland - KDE - LXDE - Mate - XFCE - TUI

The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates USB I/O requests into IP packets and transmits them between computers.

This project maintains the Linux Console tools, which include utilities to test and configure joysticks, connect legacy devices to the kernel's input subsystem (providing support for serial mice, touchscreens etc.), and test the input event layer.

New implementation of the traceroute utility for modern Linux systems. Backward compatible with the traditional traceroute. Supports both IPv4 and IPv6, additional types of trace (including TCP), allows some traces for unprivileged users.

EmuTOS is a TOS compatible operating system for Atari ST series computers, and more. It is made from Digital Research's GPLed original sources and is a free and open source alternative to Atari proprietary ROMs.

Kernelloader is a free bootloader for PS2 Linux and other Playstation 2 operating systems. Loading can be done by "Action Replay Media Player", by "memory card exploit", by "FMCB" or any other homebrew loading method. If you downloaded the latest Linux Live DVD, you need to run the online updater to be able to play Youtube videos.

libnet provides a portable framework for low-level network packet construction. This project no longer uses sourceforge, please follow it on https://github.com/libnet/libnet

PLASMA 6 is HERE (check beta iso folder). We have a new welcome app. Thank you to all the members in the ALG community for their support.

The AROS Research Operating System is an effort to implement an Open Source and portable operating system that is compatible with AmigaOS(TM). Originally, it was meant as a direct reimplementation, but already has features not existing in AmigaOS.

IEEE 802.1d ethernet bridging (plus Spanning Tree protocol) for the linux kernel. Kernel code is in Linux 2.4 and 2.6 kernels.

ToaruOS is a "complete" operating system for x86-64 PCs and experimental support for ARMv8. While many independent, hobby, and research OSes aim to experiment with new designs, ToaruOS is intended as an educational resource, providing a representative microcosm of functionality found in major desktop operating systems. The OS includes a kernel, bootloader, dynamic shared object linker, C standard library, its own composited windowing system, a dynamic bytecode-compiled programming language, advanced code editor, and dozens of other utilities and example applications. There are no external runtime dependencies and all required source code, totaling roughly 100k lines of (primarily) C, is included in this repository, save for Kuroko, which lives separately. Through out the project, ToaruOS has also attracted quite a few beginner OS developers who have tried to use it as a reference.

EasyPeasy is a lightweight operating system for netbooks, designed for the Internet and low power consumption.

Cooperative Linux is the first method for optimally running Linux on Windows and other operating systems natively. It is a port of the Linux kernel and support code that allows it to run cooperatively without emulation along with another operating system.
