-     * @brief  Adds a new TD procedure to the queue.
-     *
-     * During runtime, this is used to process TD requests during analysis of
-     * attentions other than the command complete attention (i.e. memory CEs
-     * and UEs). If there isn't a current TD procedure in progress, this
-     * function will stop background scrubbing and start this new procedure.
-     * Otherwise, this new procedure is simply added to the queue.
-     *
-     * It is possible that some of the other attentions may occur during the IPL
-     * after Hostboot has been flushed from the cache to system memory. At that
-     * point we don't have time to complete a TD procedure. Therefore, the
-     * requests will be ignored. Any chip marks placed during this time will be
-     * redetected when the runtime TD controller is initialized.
+     * @brief  This tells the TD controller there was a TdEntry added to the
+     *         queue (via pushToQueue) because of a fetch attention and
+     *         additional processing may be needed to start the next TD
+     *         procedure. If there isn't a current TD procedure in progress,
+     *         this function will stop background scrubbing and starts the first
+     *         procedure in the queue.
      *
-     * During MemDiags, this will simply add a new procedure to the queue, since
-     * we know a TD procedure will already be in progress when this is called.
+     * @pre    A TdEntry must be added to the queue (via pushToQueue) before
+     *         calling this function.
      *
      * @note   Initializes the TD controller, if needed.
      * @param  io_sc    The step code data struct.
-     * @param  i_entry  The new TD queue entry.
      * @return Non-SUCCESS if an internal function fails, SUCCESS otherwise.
