%SECTION0{name=MigrationFromVRTXToXenomaiLinux}% Case study: Migrating from RTOS (VRTXsa) to Xenomai-Linux

   * Differences
      * VRTXsa and other proprietary OSes come from one source, whereas Linux
        bears more resemblance to a toolbox with tools from different sources.
      * Get support from knowledgable people you choose yourself - not only from vendor
        (i.e. take your car to _a garage_, not to _the vendor_)

   * Advantages
      * Linux is supported on large number of systems.  Support *can not be abandoned*
        because all sources are available.
      * Build environment is *the same* as target environment
      * Huge amount of programs available (and protocols supported)
      * Very good compiler suite for C/C++ (GCC) (ever traced a compiler bug?)

   * Disadvantages
      * Different API (although the Xenomai project supports VRTX API skin)
      * Dual kernel approach
