-/* Comment :
- * Mathieu Desnoyers
- * usertrace is there only to be able to update the current CPU of the
- * usertraces when there is a schedchange. it is a way to link the ProcessState
- * to the associated usertrace. Link only created upon thread creation.
- *
- * The cpu id is necessary : it gives us back the current ProcessState when we
- * are considering data from the usertrace.

-/* This is the generic part of trace processing. All events within a
- certain time interval are accessed and processing hooks are called for
- each. The events are examined in monotonically increasing time to more
- closely follow the traced system behavior.
-
- Hooks are called at several different places during the processing:
- before traceset, after traceset, check trace, before trace, after trace,
- check tracefile, before tracefile, after tracefile,
- check_event, before_event, before_event_by_id,
- after_event, after_event_by_id.
-
- In each case the "check" hooks are called first to determine if further
- processing of the trace, tracefile or event is wanted. Then, the before
- hooks and the after hooks are called. The before hooks for a traceset
- are called before those for the contained traces, which are called before
- those for the contained tracefiles. The after hooks are called in reverse
- order. The event hooks are called after all the before_tracefile hooks
- and before all the after_tracefile hooks.
-
- The hooks receive two arguments, the hook_data and call_data. The hook_data
- is specified when the hook is registered and typically links to the
- object registering the hook (e.g. a graphical events viewer). The call_data
- must contain all the context related to the call. The traceset hooks receive
- the LttvTracesetContext provided by the caller. The trace hooks receive
- the LttvTraceContext from the traces array in the LttvTracesetContext.
- The tracefile and event hooks receive the LttvTracefileContext from
- the tracefiles array in the LttvTraceContext. The LttEvent and LttTime
- fields in the tracefile context are set to the current event and current
- event time before calling the event hooks. No other context field is
- modified.
-
- The contexts in the traces and tracefiles arrays must be allocated by
- the caller, either before the call or during the before hooks of the
- enclosing traceset or trace. The order in the traces array must
- correspond to the lttv_traceset_get function. The order in the tracefiles
- arrays must correspond to the ltt_trace_control_tracefile_get and
- ltt_trace_per_cpu_tracefile_get functions. The traceset, trace and
- tracefile contexts may be subtyped as needed. Indeed, both the contexts
- and the hooks are defined by the caller. */
