+PERF_ATQ Test
+~~~~~~~~~~~~~~~
+
+This is a performance test case that aims at testing the following with
+``all types queue`` eventdev scheme.
+
+#. Measure the number of events can be processed in a second.
+#. Measure the latency to forward an event.

+   perf all types queue test operation.
+
+
+The ``all types queues(atq)`` perf test configures the eventdev with Q queues
+and P ports, where Q and P is a function of the number of workers and number of
+producers as mentioned in :numref:`table_eventdev_perf_atq_test`.
+
+
+The atq queue test functions as same as ``perf_queue`` test. The difference
+is, It uses, ``all type queue scheme`` instead of separate queues for each
+stage and thus reduces the number of queues required to realize the use case
+and enables flow pinning as the event does not move to the next queue.

+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz
+        --slcore (Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+        --plcores
+        --wlcores
+        --stlist
+        --nb_flows
+        --nb_pkts
+        --worker_deq_depth
+        --fwd_latency
+
+Example
