Linux is a free software kernel, which combined with the GNU libraries, core utils and shell form the GNU/Linux operating system.

Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian uses the Linux kernel (the core of an operating system), but most of the basic OS tools come from the GNU project; hence the name GNU/Linux.

Filesystem in Userspace is a simple interface for userspace programs to export a virtual filesystem to the Linux kernel. It also aims to provide a secure method for non privileged users to create and mount their own filesystem implementations.

Managing device nodes in /dev on Linux.

The goals of this project are: create a new Linux kernel driver for the NTFS file system (v1.2 and later 3.0), user space utilities (e.g. format, ntfs check, etc.) and a library to avoid code duplication and provide access to NTFS to other GPLed programs

OProfile is a low-overhead, transparent profiler for Linux. It is capable of instruction-grain profiling of all processes, shared libraries, the kernel, and device drivers, via the hardware performance counters.

SystemTap provides free software (GPL) infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go ... [More] through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data. SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel. We are publishing samples, as well as enlarging the internal "tapset" script library to aid reuse and abstraction. We also plan to support probing userspace applications. We are investigating interfacing Systemtap with similar tools. [Less]

The user-mode kernel port is a port of the Linux kernel which runs in a set of processes. The result is a user-mode virtual machine and a kernel which can be debugged and developed using all of the usual process-level tools.

The goal of the Syllable project is to create a family of easy-to-use free software operating systems. It is the continuation of the BeOS-like AtheOS. Syllable Desktop has its own C kernel with symmetric multiprocessing, multithreaded pre-emptive ... [More] multitasking, high POSIX compliancy, 64-bit journaled filesystem (AFS) with metadata, an integrated native GUI architecture with an object-oriented C++ API, SDL, singular native toolkit and multi-user desktop environment. The system seeks to be an integrated, lightweight, easy-to-program, powerful, high-performance graphical desktop environment which avoids legacy OS paradigms that frustrate developers and have hindered the computing masses' adoption of a free-software desktop. Syllable Server is a matching small and efficient Linux server. [Less]

A port of the Linux kernel and tools to the iPod.

The OpenEZX project tries to gather information about the Linux-based Motorola EZX phone platform (mainly the A780, E680 and E680i phones). It further tries to provide a 100% free software stack for those phones, especially a way to avoid any ... [More] proprietary filesystem and/or device drivers. It also aims to provide a current (2.6.x) kernel with all required hardware support for the EZX phones. [Less]

µClinux is a Linux distribution like any other Linux distribution, focused on embedded projects, built from the Linux kernel from kernel.org and assorted other packages, and software from the GNU project. Since µClinux is optimized for size, it ... [More] uses more compact alternatives (busybox, µclibc, etc) than a non-embedded distribution. Pronounced "you-see-linux", the name µClinux comes from combining the greek letter "mu" and the english capital "C". "µ" stands for "micro", and the "C" is for "controller". µClinux supports embedded processors which support MMU (protection and virtual memory support), noMMU (no protection, no virtual memory) and MPU (memory protection, but no virtual memory support). The µClinux-dist includes userspace apps & libs, toolchain, c library, kernel and Bootloader. [Less]

Ensemble is an effort to write the next generation operating system using CIL compliant languages (currently only C#). The main focus of Ensemble is to write an consumer- and enterprise-level operating system that can be used in the real world.

RTAI - the RealTime Application Interface for Linux - lets you write applications with strict timing constraints for your favourite operating system.

Ksplice is practical technology for updating the Linux kernel without rebooting. It enables you to avoid the disruptive process of rebooting for kernel security updates and bugfixes. By making it easy to keep your systems up to date, Ksplice helps you avoid the security and stability risks of running out-of-date software

The Linux Kernel Virtual Machine (KVM) uses QEMU frotend to launch virtual machines. By default QEMU/KVM may only be started as root because of necessary manipulations with host network configuration. This project introduces a suid-root wrapper which ... [More] being run by a regular user, performs all system-wide actions under root privileges, and then drops privileges to the level of the user who started it. Virtual machine thus runs under user's privileges, which makes it easier to enforce access and resource control using standard Linux system mechanisms. [Less]

The Linux Cross-Reference project is the testbed application of a general hypertext cross-referencing tool. Its main goal is to create a versatile cross-referencing tool for relatively large code repositories. The main feature of the indexer is the ... [More] ability to jump easily to the declaration of any global identifier. Quick access to function declarations, data (type) definitions and preprocessor macros makes code browsing more convenient. At-a-glance overview of which code areas will be affected by changing a function or type definition should also come in useful during development and debugging. [Less]

Userspace utilities for Memory Technology Devices (MTD)

This project creates RAM based block device (named ramzswap) which acts as swap disk. Pages swapped to this disk are compressed and stored in memory itself. Compressing pages and keeping them in RAM virtually increases its capacity. This allows ... [More] more applications to fit in given amount of memory. This is especially useful for: Embedded Devices: Memory is scarce and adding more memory increases device cost. Also, flash storage suffers from wear-leveling issues, so its useful if we can avoid using them as swap device. Small Desktops (aka Virtual Machines!): De/Compression is much faster than swapping to disks (include seek times!). Of course, you also get to run VMs with much less RAM assigned. Total memory savings from individual VMs can be quite significant if multiple VMs are hosted. LiveCDs : These typically do not have any disk swap configured. Mailing Listslinux-mm-cc at laptop.org (Info Page) HelpCompilingAndUsing Patches NewsOct 03, 08 - xvMalloc: New memory allocator. This removes dependence on kernel vmalloc area. Its also quite memory efficient! Details here. Aug 13, 08 - compcache-0.4 now available. Nothing new but few bug fixes and lot of cleanups. See Changelog included for details. Jul 18, 08 - After lot more rigorous testing (on x86), compcache patches are now available from Downloads area. For help on using these patches, refer Patches. Out-of-tree kernel modules are still available. Jul 14, 08 - Patch for 2.6.26 is (here) and here is Changelog. Jun 29, 08 - Here comes patch for Linux kernel 2.6.26-rc8 (download). It fixes bug in previous patch that could cause segfault when loading module and free invalid memory in swap free notify callback. Jun 17, 08 - Patch for Linux kernel 2.6.26-rc6 for compcache is here - Its better than compcache-0.3 in terms of space efficiency, speed and also has lot of cleanups. May 13, 08 - Some Performance numbers. Apr 28, 08 - Todo list is here Mar 17, 08 - compcache-0.3 Released with more bug fixes! Mar 03, 08 - compcache-0.2 Released! Now it also exports statistics through /proc. Feb 20, 08 - compcache-0.1 Released! Feb 14, 08 - TLSFAllocator - Performance evaluation of TLSF allocator. Jan 24, 08 - SwapReplayDesign - Design and usage information. Work on allocator continues. Jan 09, 08 - SwapReplay sub-project now functional! Will post some documentation soon. Dec 21, 07 - Now compcache can dynamically resize - pages are allocated on demand and freed when not required. For now, compression structure is not yet implemented i.e. compressed page still requires 1 page for storage. Compression structure (heart of this project!) is currently under design.
