Gentoo Linux

claimed by Gentoo Foundation

Gentoo is a free operating system based on either Linux or FreeBSD that can be automatically optimized and customized for just about any application or need. Extreme configurability, performance and a top-notch user and developer community are all hallmarks of the Gentoo experience.

FreeBSD

FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98, (32-bit and 64-bit) MIPS and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of ... [More] California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development. [Less]

NetBSD

NetBSD is a free, secure, and highly portable Unix-like Open Source operating system available for many platforms, from 64-bit Opteron machines and desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research ... [More] environments, and it is user-supported with complete source. Many applications are easily available through pkgsrc, the NetBSD Packages Collection. [Less]

U-Boot

A boot loader for Embedded boards based on PowerPC, ARM, MIPS and other processors, which can be installed in a boot ROM and used to initialize and test the hardware or to download and run application code. The development of U-Boot is closely related to Linux: some parts of the source code ... [More] originate in the Linux source tree, we have some header files in common, and special provision has been made to support booting of Linux images. Some attention has been paid to make this software easily configurable and extendable. For instance, all monitor commands are implemented with the same call interface, so that it's very easy to add new commands. Also, instead of permanently adding rarely used code (for instance hardware test utilities) to the monitor, you can load and run it dynamically. [Less]

HelenOS

HelenOS is a microkernel-based multiserver operating system designed from scratch. It decomposes key operating system functionality into many isolated, intensively communicating server processes that reside entirely in user space. HelenOS thus provides a computing environment that has several ... [More] virtues, such as flexibility, increased robustness, well defined explicit interfaces and reduced complexity of individual components as compared to other operating systems. HelenOS runs on seven different processor architectures, ranging from a 32-bit uniprocessor little-endian ARMv4 to a 64-bit multicore big-endian UltraSPARC T1. [Less]

Embox

Embox is an open source real-time operating system as well as set of tools for embedded applications.

PM2

PM2 is a low level generic runtime system which integrates multithreading management (Marcel) and a high performance multi-cluster communication library (Madeleine).

AuroraUX

AuroraUX is an operating system distribution based on the OpenSolaris kernel source base. The goal of the AuroraUX project is to create a high reliability core operating system using the US Department of Defense-developed Ada programming language. While it is meant to be minimalistic and used as a ... [More] base for other distributions, it will also be functional as an operating system in itself. #auroraux @ irc.freenode.net [Less]

Machinery

Toolchain machinery for compilers, code generators, assemblers, linkers, and emulators.

dyncall

The dyncall library project provides a clean and portable C interface to dynamically issue foreign function calls using small call kernels written in assembly. Instead of providing code for every bridged function call, which unnecessarily results in code bloat, only a modest number of instructions are used to invoke all calls.
