RTLinux kernel





RTLinux Portal at Valencia


Currently RTLinux/GPL is a small, full featured, POSIX like, and fast system. The next step is to add RTLinux/GPL the required robustness to enable it to be used in carrier grade systems.

We have developed XtratuM. It is a layer of software that virtualises the processor to allows the execution of several operating systems concurrently providing isolation (both temporal and spacial) between them. Xtratum will (this feature is still not available) provide redundancy at full operating system level. That is, if a system fails, then other domain (operating systems) would recover the state and continue the operation.

Another nice feature of XtratuM is to run the guest operating system everywhere. For example: as a stand alone system, or concurrently with Linux, or even on top of Linux as a regular Linux process (in this case, no real time performance can be guarantee).

XtratuM is an exciting new project, but it is just a few months old.... so please, be patient and keep visiting its home page:

A side effect of XtratuM is that it is free of software patent as far as we know.!!

Here, in Europe, there are nothing like "software patents". After the negative experience of software patents in USA, we strongly want to live in a FREE of software patents land. If you are an European citizen, wakeup, think, act...

The ethernet card drivers initially used in the RTL-lwIP project are now developed and maintained in a separate project, called: REDD (RTLinux Ethernet Device Drivers).

A child side devoted to dynamic memory/storage allocation in real-time systems: Real-Time Dynamic Storage Allocation.

Two different portings of the MaRTE-OS executive to work jointly with Linux:

  1. Marte-OS as Linux Kernel Module (MLKM)
  2. Marte-OS as Linux User Level (MLUL)
The MLKM porting is based on the RTLinux hardware virtualisation.

You can find many more contributions to RTLinux-GPL in the OCERA web site. Also, other interesting contributions are on the way: IDE support in RTLinux-GPL, Stand-Alone RTLinux (reduced footprint, and faster!!), powerful debugger, full support to ADA language, etc.

Up to date news, brought
to you by Linuxdevices:

  1. PalmSource re-org puts Linux phones first
  2. Linux v. Windows in Gadget Smackdown round 3
  3. Linux 2.6 kernel modeled in UML 2.0
  4. Linux dev kit includes Ethernet debugger
  5. Partnership aims to replace Windows, Citrix with Linux

What can you find here?

Here you will find all the work about RT-Linux done at Group de Inform?tica Industrial. We use RTLinux in different ways:

  • As a research tool, where new theory results can be implemented and validated.
  • It is used for teaching, since RTLinux is POSIX 1003.1c compatible.
  • To control a robot.
Therefore, in this web you can find different kind of documents: tutorials, code examples, new extensions, etc.

RTLinux derived work is covered by the Open RTLinux Patent License. The rest of the code and documentation is provided as is without warranty of any kind. Most of the material not derived from RTLinux is covered by the GPL or the OPL licenses.
