verify functionality and measure the performance parameters of DPDK eventdev
devices.
-Compiling the Application
--------------------------
-
-**Build the application**
-
-Execute the ``dpdk-setup.sh`` script to build the DPDK library together with the
-``dpdk-test-eventdev`` application.
-
-Initially, the user must select a DPDK target to choose the correct target type
-and compiler options to use when building the libraries.
-The user must have all libraries, modules, updates and compilers installed
-in the system prior to this,
-as described in the earlier chapters in this Getting Started Guide.
Running the Application
-----------------------
Use event timer adapter as producer.
- * ``--prod_type_timerdev_burst``
+* ``--prod_type_timerdev_burst``
+
+ Use burst mode event timer adapter as producer.
+
+* ``--timer_tick_nsec``
+
+ Used to dictate number of nano seconds between bucket traversal of the
+ event timer adapter. Refer `rte_event_timer_adapter_conf`.
+
+* ``--max_tmo_nsec``
+
+ Used to configure event timer adapter max arm timeout in nano seconds.
+
+* ``--expiry_nsec``
+
+ Dictate the number of nano seconds after which the event timer expires.
+
+* ``--nb_timers``
+
+ Number of event timers each producer core will generate.
+
+* ``--nb_timer_adptrs``
+
+ Number of event timer adapters to be used. Each adapter is used in
+ round robin manner by the producer cores.
+
+* ``--deq_tmo_nsec``
+
+ Global dequeue timeout for all the event ports if the provided dequeue
+ timeout is out of the supported range of event device it will be
+ adjusted to the highest/lowest supported dequeue timeout supported.
+
+* ``--mbuf_sz``
+
+ Set packet mbuf size. Can be used to configure Jumbo Frames. Only
+ applicable for `pipeline_atq` and `pipeline_queue` tests.
+
+* ``--max_pkt_sz``
- Use burst mode event timer adapter as producer.
+ Set max packet mbuf size. Can be used to configure Rx/Tx scatter gather.
+ Only applicable for `pipeline_atq` and `pipeline_queue` tests.
- * ``--timer_tick_nsec``
+* ``--prod_enq_burst_sz``
- Used to dictate number of nano seconds between bucket traversal of the
- event timer adapter. Refer `rte_event_timer_adapter_conf`.
+ Set producer enqueue burst size. Can be used to configure the number of
+ events the producer(s) will enqueue as a burst to the event device.
+ Only applicable for `perf_queue` test.
- * ``--max_tmo_nsec``
+* ``--nb_eth_queues``
- Used to configure event timer adapter max arm timeout in nano seconds.
+ Configure multiple Rx queues per each ethernet port.
+ Only applicable for `pipeline_atq` and `pipeline_queue` tests.
- * ``--expiry_nsec``
+* ``--enable_vector``
- Dictate the number of nano seconds after which the event timer expires.
+ Enable event vector for Rx/Tx adapters.
+ Only applicable for `pipeline_atq` and `pipeline_queue` tests.
- * ``--nb_timers``
+* ``--vector_size``
- Number of event timers each producer core will generate.
+ Vector size to configure for the Rx adapter.
+ Only applicable for `pipeline_atq` and `pipeline_queue` tests.
- * ``--nb_timer_adptrs``
+* ``--vector_tmo_ns``
+
+ Vector timeout nanoseconds to be configured for the Rx adapter.
+ Only applicable for `pipeline_atq` and `pipeline_queue` tests.
+
+* ``--per_port_pool``
+
+ Configure unique mempool per ethernet device, the size of each pool
+ is equal to `pool_sz`.
+ Only applicable for pipeline_atq` and `pipeline_queue` tests.
- Number of event timer adapters to be used. Each adapter is used in
- round robin manner by the producer cores.
