What is the goal of this presentation? Are you aware that a standard desktop PC might spoil your realtime attempts in various ways (SMI interrupts, power management, ...)? > I wonder if a standard Linux distro + RT kernel patch would be a better choice? As long as you are using a RT kernel, sane pthreads support such as modern glibc and you know what you are doing (ksoftirqd priority and similar fun) the particular distribution does not matter much. We are using stock Debian with custom kernel as our embedded rt platform. It is the _application_ that has to be coded with several things in mind if it needs to be realtime. -- Stano
