Sorry for the crosspost, I don't know how many people are listening on [EMAIL PROTECTED] yet :-) Attached I send a new version of the RTL-mini-HOWTO. As befor you can visit it at http://www-public.rz.uni-duesseldorf.de/~jochen/computer/RT-Linux/RTL-mini-HOWTO.html This is not an official site yet, though. Please don't bookmark it or even provide links - it will end up in a very different URL after publication. I want to encourage everybody to look at the doc and provide feedback. Esp. missing links, corrections and descriptions of the various systems are needed. Whatever _you_ consider important is wellcome :-) Cheers, -- Jochen Heinrich-Heine-Universität, Institut für Physikalische Chemie I Universitätsstr. 1, Geb. 26.43.02.29, 40225 Düsseldorf, Germany phone 02118113681 fax 02118115195 -- www-public.rz.uni-duesseldorf.de/~jochen [EMAIL PROTECTED] -- [EMAIL PROTECTED] -- [EMAIL PROTECTED]

Dezember 1999 \layout Abstract This document is an introduction into Real-Time Linux in general. It is intended to help people to learn about the availability and performance of these systems. As such it is not intended to replace real documentation of Real-Time Linux systems, but shall provide an entry point into Real-Time Linux world. \layout Standard \begin_inset LatexCommand \tableofcontents{} \end_inset \layout Section Introduction \layout Subsection What is \emph on Real-Time \emph default Linux ? \layout Standard It is not an easy question to answer what a \emph on Real-Time \emph default system is in general. A description of the main principles might include \layout Itemize The system is capable of performing some specific work within guaranteed resource constraints. \layout Itemize Timing constraints are usually in the sub-ms area, not minutes. \layout Itemize The uncertainty timing is defined and low (typically < 25 us). It is kept in any circumstances. \layout Itemize 100% reliability. \layout Standard There are several Linux based approaches available that address the specific needs of \emph on Real-Time \emph default systems - that is what we call \emph on Real-Time \emph default Linux. \layout Standard This document is supposed to help you find information on all the \emph on Real-Time \emph default Linux systems available. For first descriptions of these systems, how to obtain them, and for pointers to additional information look at section \begin_inset LatexCommand \ref[Getting Started]{GettingStarted} \end_inset . \layout Subsection History \layout Standard This document was started on 16. December 1999 by \begin_inset LatexCommand \url[Jochen Küpper]{mailto:[EMAIL PROTECTED]} \end_inset right after the first \emph on Real-Time \emph default Linux Workshop in Vienna. \layout Subsection New versions \layout Standard New versions of this document can be obtained from my \begin_inset LatexCommand \url[web-page]{http://www-public.rz.uni-duesseldorf.de/~jochen} \end_inset and hopefully soon from the \begin_inset LatexCommand \url[Linux Documentation project]{http://www.linuxdoc.org} \end_inset and \begin_inset LatexCommand \url[realtimelinux.org]{http://www.realtimelinux.org} \end_inset as well. \layout Subsection Copyrights and Trademarks \layout Standard This document is Copyright (C) 1999 Jochen Küpper. \layout Standard It may be reproduced in whole or in part, without fee, subject to the following restrictions: \layout Itemize The copyright notice above and this permission notice must be preserved complete on all complete or partial copies. \layout Itemize Any translation or derived work must be approved by the author in writing before distribution. \layout Itemize If you distribute this work in part, instructions for obtaining the complete version of this manual must be included, and a means for obtaining a complete version provided. \layout Itemize Small portions may be reproduced as illustrations for reviews or quotes in other works without this permission notice if proper citation is given. \layout Standard Exceptions to these rules may be granted for academic purposes: Write to the author and ask.

Especially the \emph on Real-Time \emph default Linux workshop in Vienna provided a wealth of information to this document. \layout Section Getting Started \begin_inset LatexCommand \label{GettingStarted} \end_inset \layout Subsection Available \emph on Real-Time \emph default Linux Systems \layout Subsubsection NMT RT-Linux \layout Standard This was the very first implementation on a Linux-based hard \emph on real-time \emph default system. \layout Standard At the time it is at version 2.0. It nativly offers a POSIX like API, doesn't conform completely, though. It supports uniprocessor and SMP x86 based machines. It is activly maintained by the group of Victor Yodaiken at the New Mexico Institut of Technology and Mining. \layout Subsubsection DIAPM RTAI \layout Standard This Real Time Application Interface (RTAI) is a split-off of version 1 of NMT RT-Linux using a very powerfull native API similar to the NMT RT-Linux v1 API. A POSIX API wrapper based on the LinuxThreads package is available within the distribution. RTAI is activly maintained by the group of Paolo Mategazza at Dipartimento di Ingegneria Aerospaziale Politecnico di Milano, Italy. \layout Subsubsection KURT \layout Standard The \emph on real-time \emph default modifications to the standard Linux kernel from Douglas Niehaus' group aim at good soft \emph on real-time \emph default performance with small changes to the standard system. \layout Subsubsection Linux/RK \layout Standard This is a resource kernel implementation based on Linux. It puts an \emph on portable resource kernel \emph default besides the standad Linux kernel and tries to guaranty access to certain specified resources to applications. \layout Subsubsection RED-Linux \layout Subsubsection SMART \layout Standard A soft \emph on real-time \emph default system aiming at good multimedia-performance on heavy-loaded systems. \layout Subsection Obtaining RT-Linux \layout Standard All \emph on Real-Time \emph default Linux systems described herein can be downloaded on the Internet. Look at section \begin_inset LatexCommand \ref[Further Information]{FurtherInformation} \end_inset for the homepages of the products you are interested in. There you will find links to their homepages, these will give you detailed instructions how to obtain and install the respective system. \layout Standard Furthermore there are several companies offering paid professional support on \emph on Real-Time \emph default Linux systems, a list of which can be found in section \begin_inset LatexCommand \ref[Companies]{Companies} \end_inset . \layout Subsection Installation \layout Standard For various reasons installation instructions of the different \emph on Real-Time \emph default Linux systems are not included here! \layout Standard If this document would include real installation instructions, to my mind these would need to be very comprehensive and enable any new user to install \emph on Real-Time \emph default Linux. This would blow up this document to much though, and also would make it very hard to maintain - therefore in here a general installation scheme and links to individual installation instructions of all systems are given. \layout Subsubsection General installation scheme \layout Standard If you do not really understand what this section is all about, don't worry to much - it is intended to give you a sketch of what is needed to do, but in no way replaces comprehensive installation instructions available at the sites listed in section \begin_inset LatexCommand \ref[Comprehensive Installation Instructions]{InstallationLinks} \end_inset . \layout Standard To install any \emph on Real-Time \emph default Linux system you first have to obtain the respective \emph on Real-Time \emph default Linux distribution, look at the projects homepages listed in section \begin_inset LatexCommand \ref[Web-pages]{Webpages} \end_inset . You also need a fresh Linux kernel matching you \emph on Real-Time \emph default Linux distribution. Usually that is the latest stable Linux kernel - currently \family typewriter 2.2.13 \family default . After unpacking them you have modify the Linux kernel, most easily done by some means of patching it. Then you need to configure, build, install, and reboot the kernel as you would do with any plain kernel. Afterwards you need to compile the \emph on Real-Time \emph default Linux system and insert the modules providing the functionality you wish to use. \layout Standard At this pointed you definitly should look at the examples provided with all distributions and get into \emph on Real-Time \emph default Linux world, ... . \layout Subsubsection Comprehensive Installation Instructions \begin_inset LatexCommand \label{InstallationLinks} \end_inset \layout Standard Well, that stuff needs to be done soon. We should probably make a short lyx or sgml doc for every system and put all of them onto one site - at least html and ps/pdf :-) \layout Standard Phil's on NMT-RTL and RTAI are a very nice starting point, I guess. \layout Section Further information \begin_inset LatexCommand \label{FurtherInformation} \end_inset \layout Subsection Web-pages \begin_inset LatexCommand \label{Webpages} \end_inset \layout Standard General information, documentation and links can be found at the \begin_inset LatexCommand \url[Real-Time Linux Portal]{http://www.realtimelinux.org} \end_inset . Looking for supported hardware the \begin_inset LatexCommand \url[Comprehensive Real-Time Linux Archive Network]{http://www.realtimelinux.org/CRAN} \end_inset might be helpfull. \layout Standard Moreover there are distribution specific pages available, some of which actually contain a lot of information for users of other \emph on Real-Time \emph default Linux systems as well. (There is no meaning to the order of this list, but simply the time I happended to got aware of these pages.) \layout Itemize \begin_inset LatexCommand \url[RT-Linux at NMT]{http://www.rtlinux.org} \end_inset \layout Itemize \begin_inset LatexCommand \url[RTAI at DIAPM]{http://www.rtai.org} \end_inset \layout Itemize \begin_inset LatexCommand \url[KURT]{http://hegel.ittc.ukans.edu/projects/kurt/} \end_inset \layout Itemize Linux/RK - nothing on the web yet ? \layout Itemize \begin_inset LatexCommand \url[RED-Linux]{http://} \end_inset \layout Itemize \begin_inset LatexCommand \url[SMART]{http://} \end_inset Scheduling Multimedia Applications for Linux. \layout Standard Other \emph on Real-Time \emph default Linux related sites are \layout Itemize \begin_inset LatexCommand \url[pk]{http://www.cornfed.com/pk} \end_inset : A POSIX Threads Kernel. \layout Itemize The \begin_inset LatexCommand \url[EL/IX]{http://sourceware.cygnus.com/elix/} \end_inset API. \layout Subsection Mailing Lists \layout Standard There are several mailing lists available to discuss \emph on Real-Time \emph default Linux topics. Non system specific lists are \layout Itemize \begin_inset LatexCommand \url[Real-Time Linux mailing list]{mailto:[EMAIL PROTECTED]} \end_inset for all general discussions of \emph on Real-Time \emph default Linux systems and applications. \begin_inset LatexCommand \url[Subscription information]{http://www.realtimelinux.org/maillist.html} \end_inset and an \begin_inset LatexCommand \url[archive]{http://www.realtimelinux.org/archives/realtime} \end_inset are available. \layout Itemize \begin_inset LatexCommand \url[Real-Time Linux documentation mailing list]{mailto:[EMAIL PROTECTED]} \end_inset for discussions related to \emph on Real-Time \emph default Linux documentation. \layout Standard System specific lists are \layout Itemize The \begin_inset LatexCommand \url[rtlinux mailing list]{mailto:[EMAIL PROTECTED]} \end_inset for discussions of NMT \emph on Real-Time \emph default Linux. RTAI discussions go here as well. An \begin_inset LatexCommand \url[archive]{http://rtlinux.cs.nmt.edu/cgi-bin/wilma/rtl} \end_inset is available. \layout Itemize The \begin_inset LatexCommand \url[KURT mailing list]{mailto:[EMAIL PROTECTED]} \end_inset . \layout Section Applications \layout Standard In here pointers to selected applications of \emph on Real-Time \emph default Linux applications are given. Overall these projects nicely show the strength and flexibility of \emph on Real-Time \emph default Linux systems: \layout Itemize \begin_inset LatexCommand \url[Digital control of dynamic systems]{http://server.aero.polimi.it/projects/rtl_variant/articolo/RTLart.html} \end_inset . \layout Itemize A \begin_inset LatexCommand \url[Biomedical Experiment interface]{http://cardiodyn.med.cornell.edu/~dchristi/rtlinux} \end_inset . Christini, D.J., et al., \shape italic Annals of Biomedical Engineering \shape default 27(1999), 180. \layout Standard ( Does it make sense to create a page with links to _all_ applications of \emph on Real-Time \emph default Linux systems ? Anybody willing to maintain that ? ) \layout Section \emph on Real-Time \emph default Linux product vendors \begin_inset LatexCommand \label{Companies} \end_inset \layout Standard Several companies provide professional development and support resources for \emph on Real-Time \emph default Linux systems: \layout Itemize \begin_inset LatexCommand \url[FSM Labs]{http://www.fsmlabs.com} \end_inset \layout Itemize \begin_inset LatexCommand \url[Zentropix]{http://www.zentropix.com} \end_inset \layout Section FAQs \layout Standard ( Probably just a pointer to a real FAQ in here, I guess. There is none yet, though :-) \the_end
