Day 2: Conferences: RT-Linux Manifesto



Victor Yokaiken started on giving a definition of what realtime, or hard realtime really is (in essence, it has nothing to do with speed, or average response rate, but an exact figure of what the worst case response time it).

I took pictures of his slides, and you can find them in the middle of picture gallery. Victor informed me that they are copyrighted and that you should contact him before copying them. They are used here with his permission.

Rewriting a realtime OS from scratch for a certain platform is a lot of work, especially if you want TCP/IP, graphical modes, etc, etc...

The idea of this project is to leverage the existing linux code and still take have a hard realtime OS and the way this is done is that the linux kernel is run as the idle task of a small RTOS and communication is mainly done through FIFOs

RT Linux has already been used for various things, like animating robots in movies, there are plans to use it for demining robots and the NASA also has a real time acquisition device that fits under a plane.
