\r
384 * Macro which should be defined as either zero (0) or one (1).
\r
387 * ### Instance Finish Events (IFE) ###
\r
389 * For tasks with "infinite" main loops (non-terminating tasks), the concept
\r
390 * of a task instance has no clear definition, it is an application-specific
\r
391 * thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
\r
392 * which marks the point in a cyclic task when the "task instance" ends.
\r
393 * The IFE is a blocking kernel call, typically in the main loop of a task
\r
394 * which typically reads a message queue, waits for a semaphore or performs
\r
395 * an explicit delay.
\r
397 * If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
\r
398 * will define what kernel calls are considered by default to be IFEs.
\r
400 * However, Implicit IFEs only applies to blocking kernel calls. If a
\r
401 * service reads a message without blocking, it does not create a new
\r
402 * instance since no blocking occurred.
\r
404 * Moreover, the actual IFE might sometimes be another blocking call. We
\r
405 * therefore allow for user-defined Explicit IFEs by calling
\r
407 * vTraceTaskInstanceIsFinished()
\r
409 * right before the kernel call considered as IFE. This does not create an
\r
410 * additional event but instead stores the service code and object handle
\r
411 * of the IFE call as properties of the task.
\r
413 * If using Explicit IFEs and the task also calls an Implicit IFE, this may
\r
414 * result in additional incorrect task instances.
\r
415 * This is solved by disabling the Implicit IFEs for the task, by adding
\r
418 * vTraceTaskSkipDefaultInstanceFinishedEvents()
\r
420 * in the very beginning of that task. This allows you to combine Explicit IFEs
\r
421 * for some tasks with Implicit IFEs for the rest of the tasks, if
\r
422 * USE_IMPLICIT_IFE_RULES is 1.
\r
424 * By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
\r
425 * for all tasks. Tasks will then be considered to have a single instance only,
