// of executables differ largely in the available functionality of
// the C-library, STL, and so on. A DKM uses a library similar to those
// of vxWorks 5.X - with all its limitations and incompatibilities
// in respect to ANSI C++ and STL. So probably there might be problems
// with respect to ANSI C++ and STL. So probably there might be problems
// with the usage of boost from DKMs. WRS or any voluteers are free to
// prove the opposite!
// ====================================================================
//
// Some important information regarding the usage of POSIX semaphores:
// -------------------------------------------------------------------
//
// VxWorks as a real time operating system handles threads somewhat
// different from what "normal" OSes do, regarding their scheduling!
// This could lead to a scenario called "priority inversion" when using
// semaphores, see http://en.wikipedia.org/wiki/Priority_inversion.
//
// Now, VxWorks POSIX-semaphores for DKM's default to the usage of
// priority inverting semaphores, which is fine. On the other hand,
// for RTP's it defaults to using non priority inverting semaphores,
// which could easily pose a serious problem for a real time process,
// i.e. deadlocks! To overcome this two possibilities do exist:
//
// a) Patch every piece of boost that uses semaphores to instanciate
// the proper type of semaphores. This is non-intrusive with respect
// to the OS and could relatively easy been done by giving all
// semaphores attributes deviating from the default (for in-depth
// information see the POSIX functions pthread_mutexattr_init()
// and pthread_mutexattr_setprotocol()). However this breaks all
// too easily, as with every new version some boost library could
// all in a sudden start using semaphores, resurrecting the very
// same, hard to locate problem over and over again!
//
// b) We could change the default properties for POSIX-semaphores
// that VxWorks uses for RTP's and this is being suggested here,
// as it will more or less seamlessly integrate with boost. I got
// the following information from WRS how to do this, compare
// Wind River TSR# 1209768:
//
// Instructions for changing the default properties of POSIX-
// semaphores for RTP's in VxWorks 6.9:
// - Edit the file /vxworks-6.9/target/usr/src/posix/pthreadLib.c
// in the root of your Workbench-installation.
// - Around line 917 there should be the definition of the default
// mutex attributes:
//
// LOCAL pthread_mutexattr_t defaultMutexAttr =
// {
// PTHREAD_INITIALIZED_OBJ, PTHREAD_PRIO_NONE, 0,
// PTHREAD_MUTEX_DEFAULT
// };
//
// Here, replace PTHREAD_PRIO_NONE by PTHREAD_PRIO_INHERIT.
// - Around line 1236 there should be a definition for the function
// pthread_mutexattr_init(). A couple of lines below you should
// find a block of code like this:
//
// pAttr->mutexAttrStatus = PTHREAD_INITIALIZED_OBJ;
// pAttr->mutexAttrProtocol = PTHREAD_PRIO_NONE;
// pAttr->mutexAttrPrioceiling = 0;
// pAttr->mutexAttrType = PTHREAD_MUTEX_DEFAULT;
//
// Here again, replace PTHREAD_PRIO_NONE by PTHREAD_PRIO_INHERIT.
// - Finally, rebuild your VSB. This will create a new VxWorks kernel
// with the changed properties. That's it! Now, using boost should
// no longer cause any problems with task deadlocks!
//
// And here's another useful piece of information concerning VxWorks'
// POSIX-functionality in general:
// VxWorks is not a genuine POSIX-OS in itself, rather it is using a
// kind of compatibility layer (sort of a wrapper) to emulate the
// POSIX-functionality by using its own resources and functions.
// At the time a task (thread) calls it's first POSIX-function during
// runtime it is being transformed by the OS into a POSIX-thread.
// This transformation does include a call to malloc() to allocate the
// memory required for the housekeeping of POSIX-threads. In a high
// priority RTP this malloc() call may be highly undesirable, as its
// timing is more or less unpredictable (depending on what your actual
// heap looks like). You can circumvent this problem by calling the
// function thread_self() at a well defined point in the code of the
// task, e.g. shortly after the task spawns up. Thereby you are able
// to define the time when the task-transformation will take place and
// you could shift it to an uncritical point where a malloc() call is
// tolerable. So, if this could pose a problem for your code, remember
// to call thread_self() from the affected task at an early stage.
//
// ====================================================================
// Block out all versions before vxWorks 6.x, as these don't work:
// Include header with the vxWorks version information and query them
#include <version.h>
