CONFIG_PERCEPIO_RECORDER_TRC_CFG_USE_IMPLICIT_IFE_RULES

Use Implicit IFE Rules

Type: bool

Help

Tracealyzer groups the events into "instances" based on Instance Finish
Events (IFEs), produced either by default rules or calls to the recorder
functions vTraceInstanceFinishedNow and vTraceInstanceFinishedNext.

If TRC_CFG_USE_IMPLICIT_IFE_RULES is one (1), the default IFE rules is
used, resulting in a "typical" grouping of events into instances.
If these rules don't give appropriate instances in your case, you can
override the default rules using vTraceInstanceFinishedNow/Next for one
or several tasks. The default IFE rules are then disabled for those tasks.

If TRC_CFG_USE_IMPLICIT_IFE_RULES is zero (0), the implicit IFE rules are
disabled globally. You must then call vTraceInstanceFinishedNow or
vTraceInstanceFinishedNext to manually group the events into instances,
otherwise the tasks will appear a single long instance.

The default IFE rules count the following events as "instance finished":
  - Task delay, delay until
  - Task suspend
  - Blocking on "input" operations, i.e., when the task is waiting for the
  next a message/signal/event. But only if this event is blocking.
