SDIOS06 - Source Code and Ready-To-Run Image

Posted on 2006-09-14 09:26 by Timo Bingmann at Permlink with 2 Comments. Tags: sdios06 university c++

As promised the source code to SDIOS06 was released under the GPL.

SDIOS06 is a toy operating system developed during the practical course SDI (System Design and Implementation) at the Systems Architecture Group of the University of Karlsruhe. It was designed and written by Timo Bingmann, Matthias Braun, Torsten Geiger and Andreas Mähler. Two games were ported to a custom SDL implementation using the VMware "hard"-ware: SDLjump and SuperTux. For more information and screenshots see my blog entry 20060727-SDI-Demo.

The source code archive was published on the L4Ka.org page: http://www.l4ka.org/86.php

A local copy of the source archive (7.4 MB) is available as well. The README file contains a great deal of information about SDIOS06's design and modules. The complete source code can be browsed on the web.

To make demonstration as easy as possible a ready-to-run binary vmware image (3.8 MB) can be downloaded. The image contains SDIOS06 installed on a virtual vmware disk image. The VMware image can be run using the free VMware Player.


Presented Practical Work for SDI (System Design and Implementation)

Today was the final demo presentation day for the practical course SDI (System Design and Implementation) at the Systems Architecture Group of the University of Karlsruhe. Goal of the course was to implement a simple operating system on top of the L4 microkernel, which is developed at the Group.

SDIJump

Our practical course group was one of the two groups to demonstrate a working system on the last day of the semester. The presented operating system contained following basic components:

Furthermore we utilized the VMWare video "card" to enable graphics output. The "hardware" is well documented in the source code to the X11 video driver contributed by VMWare.

The frame buffer and keyboard input was linked up to a ported SDL implementation. After adding a lot of POSIX library function calls like fopen, opendir and getenv, it was possible to compile our favourite games: SDLjump and SuperTux. Both run very well on our operating system from scratch project.

Some screenshots of the shell, sdijump and supertux are available. In future the whole source code and compiled binary images may become available

A big thank you to my friends Matthias Braun, Torsten Geiger and Andreas Mähler, who made this practical work possible and especially fun!
