31 dpdk-test-eventdev Application
32 ==============================
34 The ``dpdk-test-eventdev`` tool is a Data Plane Development Kit (DPDK)
35 application that allows exercising various eventdev use cases.
36 This application has a generic framework to add new eventdev based test cases to
37 verify functionality and measure the performance parameters of DPDK eventdev
40 Compiling the Application
41 -------------------------
43 **Build the application**
45 Execute the ``dpdk-setup.sh`` script to build the DPDK library together with the
46 ``dpdk-test-eventdev`` application.
48 Initially, the user must select a DPDK target to choose the correct target type
49 and compiler options to use when building the libraries.
50 The user must have all libraries, modules, updates and compilers installed
51 in the system prior to this,
52 as described in the earlier chapters in this Getting Started Guide.
54 Running the Application
55 -----------------------
57 The application has a number of command line options:
59 .. code-block:: console
61 dpdk-test-eventdev [EAL Options] -- [application options]
66 The following are the EAL command-line options that can be used in conjunction
67 with the ``dpdk-test-eventdev`` application.
68 See the DPDK Getting Started Guides for more information on these options.
70 * ``-c <COREMASK>`` or ``-l <CORELIST>``
72 Set the hexadecimal bitmask of the cores to run on. The corelist is a
75 * ``--vdev <driver><id>``
77 Add a virtual eventdev device.
82 The following are the application command-line options:
86 Set verbose level. Default is 1. Value > 1 displays more details.
90 Set the device id of the event device.
94 Set test name, where ``name`` is one of the following::
101 * ``--socket_id <n>``
103 Set the socket id of the application resources.
107 Set the number of mbufs to be allocated from the mempool.
111 Set the scheduler lcore id.(Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
113 * ``--plcores <CORELIST>``
115 Set the list of cores to be used as producers.
117 * ``--wlcores <CORELIST>``
119 Set the list of cores to be used as workers.
121 * ``--stlist <type_list>``
123 Set the scheduled type of each stage where ``type_list`` size
124 determines the number of stages used in the test application.
125 Each type_list member can be one of the following::
127 P or p : Parallel schedule type
128 O or o : Ordered schedule type
129 A or a : Atomic schedule type
131 Application expects the ``type_list`` in comma separated form (i.e. ``--stlist o,a,a,a``)
135 Set the number of flows to produce.
139 Set the number of packets to produce. 0 implies no limit.
141 * ``--worker_deq_depth <n>``
143 Set the dequeue depth of the worker.
147 Perform forward latency measurement.
149 * ``--queue_priority``
151 Enable queue priority.
