Advanced Linux Sound Architecture (ALSA)

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system. ALSA has the following significant features: * Efficient support for all types of audio interfaces, from consumer sound cards to professional multichannel audio interfaces. * Fully ... [More] modularized sound drivers. * SMP and thread-safe design. * User space library (alsa-lib) to simplify application programming and provide higher level functionality. * Support for the older Open Sound System (OSS) API, providing binary compatibility for most OSS programs.

Linux NTFS file system support

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

MacFUSE

MacFUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on Mac OS X (10.4 and above). It aims to be API-compliant with the FUSE (File-system in USErspace) mechanism that originated on Linux. Therefore, many existing FUSE file systems ... [More] become readily usable on Mac OS X. The core of MacFUSE is in a dynamically loadable kernel extension. Although MacFUSE has a completely different kernel-level implementation from Linux FUSE, it supports the FUSE specification well enough that many popular FUSE file systems can be easily compiled and work on Mac OS X--often out of the box.

v4l2loopback

this is v4l2 loopback device which output is it's own input. this is useful for feeding different v4l2 applications with video from non v4l2 sources, for example one can feed Skype with video enhanced by gstreamer effects; or use input device which does not have v4l2 compliant driver. code ... [More] is based on avld driver, but in fact it is a complete rewrite and final version unlikely will share common code. [Less]

virtualdisk

Virtual Disk project plan to create a file based virtual disk tools. It will provides simple file management and many features, such as security, snapshot etc.

managarm

Managarm is a modern operating system that is based on a virtual machine. Its objective is to provide a fast and stable operating system for daily use. Managarms device drivers are written in a managed programming language and are verified before executed. Modern virtual machine and just-in-time ... [More] compilation techniques are used to achieve high performance without risking a loss of stability and security. At the moment Managarm is in the very early stages of development and only few programs are supported. It is available for the Intel x86 (Pentium or better) architecture, however, it could be easily ported to other platforms. Managarm is primarily written in the Korona programming language that was specifically designed for managed operating system and driver code. Some parts of the runtime library are written in assembly language; some utilities and applications are written in Java. Currently Managarm's virtual machine only runs its own bytecode format, later also Java bytecode will be supported. It would be possible to implement a frontend for .NET but that is not planned to be realized in the near future. [Less]

migloop

VM live-migration has been proved to be a useful technology, which can be used to provide a alway-online service, or VM-based workload balancing. In order to migrate a VM from one host to anthoer, two hard disks with same content must exist on both sides. Usually this is achieved by mounting the ... [More] same network storage system on both sides. But if the two hosts involved in live-migration locate in different networks, using network storage would be very slow. migloop is usful in the situation that migration hosts does not share a network disk. migloop is a special loopback device driver which has two modes, namely write-limit mode, and read-limit mode. When VM live-migration begins, the VM virtual hard disk on source host should work in write-limit mode which allows no-limit read operation, and limited write opertion recording which disk offsets are overwritten. While the VM still running on the source host, the virtual hard disk can be transfered to migration destination host in background, with migloop recording all the concurrent changes made to the disk. After virtual hard disk is transfered to destination host, VM can be migrated immediately while migloop working in read-limit mode on the destination host. In read-limit mode, migloop is configured with a list of disk offsets that does not allow read/write operation yet. In this way, VM can run on dest-host without worrying about disk inconsistency, while differentiation is transferring in background. [Less]

geminis

This remote administration tool is designed for Windows. The main diference with the existing ones is that it runs at driver level. It means that is not vulnerable to attacks generated by low privilege process. With this remote administration tool you have total access to Kernel.

motion-sensed-lcd-linux-driver

This a project for the real time device drivers course at FSU by a group of 3 students. We plan to create a simple driver and a user level application for a lcd device which would be activated by a motion sensor.

ThinkPad ACPI Extras Driver

This is a Linux driver for ThinkPad laptops, written by Borislav Deianov and Henrique de Moraes Holschuh. It aims to support various features of these laptops which are accessible through a ThinkPad-specific ACPI framework.
