[dpdk-dev] [PATCH 00/33] introduce generic eventdev test application framework

[dpdk-dev] [PATCH 00/33] introduce generic eventdev test application framework

[Jerin Jacob]

The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK)
application that allows exercising various eventdev use cases. This
application has a generic framework to add new eventdev based test cases
to verify functionality and measure the performance parameters of DPDK
eventdev devices.

This patch set adds the infrastructure for the generic eventdev test cases
framework with four test cases.

1)perf_queue: test to measure the throughput and forward latency of eventdev
pipeline on different PMDs
2)perf_atq: functionally same as perf_queue. But using "all type queues"
eventdev infrastructure
3)order_queue: test to verify the ingress event ordering and atomic
schedule type
4)order_atq: functionally same as order_queue. But using "all types queues"
eventdev infrastructure.

The tests are verified using both HW(OCTEONTX) and SW eventdev PMDs.

We need minor changes in the API specification to run this test cases on HW PMD.
I will send those patches separately.

Since "all type queues" is not currently supported in SW implementation.
"All types queue" based tests returns "unsupported" on SW PMD.

Added detailed documentation for test operation and usage with diagrams in the
last five patches in the series.

[dpdk-dev] [PATCH 04/33] app/testeventdev: add string parsing helpers

[Jerin Jacob]

From: Guduri Prathyusha <gprathyusha@caviumnetworks.com>

Add a couple of help functions that will allow parsing many types of
input parameters, i.e.: bool, 16, 32, 64 bits, hex and list of cores etc.

Derived from examples/ip_pipeline/parser.h

[dpdk-dev] [PATCH 16/33] app/testeventdev: add order queue test

[Jerin Jacob]

The order queue test configures the eventdev with two queues
and an event producer to inject the events to q0(ordered) queue.
Both q0(ordered) and q1(atomic) are linked to all the workers.

The event producer maintains a sequence number per flow and
injects the events to the ordered queue.

The worker receives the events from ordered queue and
forwards to atomic queue. Since the events from an ordered queue can
be processed in parallel on the different workers, the
ingress order of events might have changed on the downsteam
atomic queue enqueue. On enqueue to the atomic queue, the eventdev PMD
driver reorders the event to the original ingress order
i.e producer ingress order).

When the event is dequeued from the atomic queue by the worker,
this test verifies the expected
sequence number of associated event per flow by comparing
the free running expected sequence number per flow.

Example command to run order queue test:

sudo build/app/dpdk-test-eventdev --vdev=event_sw0 --\
--test=order_queue --plcore 1 --wlcores 2,3

[dpdk-dev] [PATCH 18/33] app/testeventdev: add order "all types queue" test

[Jerin Jacob]

This test verifies the same aspects of order_queue test,
The difference is the number of queues used, this test
operates on a single "all types queue"(atq) instead of two
different queues for ordered and atomic.

Example command to run order all types queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=order_atq --plcore 1 --wlcores 2,3

[dpdk-dev] [PATCH 19/33] app/testeventdev: perf: add test setup and destroy

[Jerin Jacob]

perf test has the queue and all types queue variants.
Introduce test_perf_common* to share the common code between those tests.

[dpdk-dev] [PATCH 24/33] app/testeventdev: add perf queue test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The perf queue test configures the eventdev with Q queues and P ports,
where Q is nb_producers * nb_stages and P is nb_workers + nb_producers.

The user can choose the number of workers, the number of producers and
number of stages through the --wlcores , --plcores and the --stlist
application command line arguments respectively.

The producer(s) injects the events to eventdev based the
first stage sched type list requested by the user through --stlist
the command line argument.

Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and
terminates when it reaches the last stage in the pipeline.
On event termination, application increments the number events
processed and print periodically in one second to get the
number of events processed in one second.

When --fwd_latency command line option selected, the application
inserts the timestamp in the event on the first stage and then
on termination, it updates the number of cycles to forward
a packet. The application uses this value to compute the average
latency to a forward packet.

Example command to run perf queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- --test=perf_queue\
--slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

[dpdk-dev] [PATCH 26/33] app/testeventdev: add perf "all types queue" test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

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.

Example command to run perf "all types queue" test:

sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

+
+dpdk-test-eventdev Application
+==============================
+
+The ``dpdk-test-eventdev`` tool is a Data Plane Development Kit (DPDK)
+application that allows exercising various eventdev use cases.
+This application has a generic framework to add new eventdev based test cases to
+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
+-----------------------
+
+The application has a number of command line options:
+
+.. code-block:: console
+
+   dpdk-test-eventdev [EAL Options] -- [application options]
+
+EAL Options
+~~~~~~~~~~~
+
+The following are the EAL command-line options that can be used in conjunction
+with the ``dpdk-test-eventdev`` application.
+See the DPDK Getting Started Guides for more information on these options.
+
+*   ``-c <COREMASK>`` or ``-l <CORELIST>``
+
+        Set the hexadecimal bitmask of the cores to run on. The corelist is a
+        list of cores to use.
+
+*   ``--vdev <driver><id>``
+
+        Add a virtual eventdev device.
+
+Application Options
+~~~~~~~~~~~~~~~~~~~
+
+The following are the application command-line options:
+
+* ``--verbose``
+
+        Set verbose level. Default is 1. Value > 1 displays more details.
+
+* ``--dev <n>``
+
+        Set the device id of the event device.
+
+* ``--test <name>``
+
+        Set test name, where ``name`` is one of the following::
+
+         order_queue
+         order_atq
+         perf_queue
+         perf_atq
+
+* ``--socket_id <n>``
+
+        Set the socket id of the application resources.
+
+* ``--pool-sz <n>``
+
+        Set the number of mbufs to be allocated from the mempool.
+
+* ``--plcore <n>``
+
+        Set the producer lcore id.
+
+* ``--slcore <n>``
+
+        Set the scheduler lcore id.(Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+
+* ``--plcores <CORELIST>``
+
+        Set the list of cores to be used as producers.
+
+* ``--wlcores <CORELIST>``
+
+        Set the list of cores to be used as workers.
+
+* ``--stlist <type_list>``
+
+        Set the scheduled type of each stage where ``type_list`` size
+        determines the number of stages used in the test application.
+        Each type_list member can be one of the following::
+
+            P or p : Parallel schedule type
+            O or o : Ordered schedule type
+            A or a : Atomic schedule type
+
+        Application expects the ``type_list`` in comma separated form (i.e. ``--stlist o,a,a,a``)
+
+* ``--nb_flows <n>``
+
+        Set the number of flows to produce.
+
+* ``--nb_packets <n>``
+
+        Set the number of packets to produce.
+
+* ``--worker_deq_depth <n>``
+
+        Set the dequeue depth of the worker.
+
+* ``--fwd_latency``
+
+        Perform forward latency measurement.
+
+* ``--queue_priority``
+
+        Enable queue priority.

+   order queue test operation.
+
+The order queue test configures the eventdev with two queues and an event
+producer to inject the events to q0(ordered) queue. Both q0(ordered) and
+q1(atomic) are linked to all the workers.
+
+The event producer maintains a sequence number per flow and injects the events
+to the ordered queue. The worker receives the events from ordered queue and
+forwards to atomic queue. Since the events from an ordered queue can be
+processed in parallel on the different workers, the ingress order of events
+might have changed on the downsteam atomic queue enqueue. On enqueue to the
+atomic queue, the eventdev PMD driver reorders the event to the original
+ingress order(i.e producer ingress order).
+
+When the event is dequeued from the atomic queue by the worker, this test
+verifies the expected sequence number of associated event per flow by comparing
+the free running expected sequence number per flow.

+ORDER_ATQ Test
+~~~~~~~~~~~~~~
+

+   perf queue test operation.
+
+The perf queue test configures the eventdev with Q queues and P ports, where
+Q and P is a function of the number of workers, the number of producers and
+number of stages as mentioned in :numref:`table_eventdev_perf_queue_test`.
+
+The user can choose the number of workers, the number of producers and number of
+stages through the ``--wlcores``, ``--plcores`` and the ``--stlist`` application
+command line arguments respectively.
+
+The producer(s) injects the events to eventdev based the first stage sched type
+list requested by the user through ``--stlist`` the command line argument.
+
+Based on the number of stages to process(selected through ``--stlist``),
+The application forwards the event to next upstream queue and terminates when it
+reaches the last stage in the pipeline. On event termination, application
+increments the number events processed and print periodically in one second
+to get the number of events processed in one second.
+
+When ``--fwd_latency`` command line option selected, the application inserts
+the timestamp in the event on the first stage and then on termination, it
+updates the number of cycles to forward a packet. The application uses this
+value to compute the average latency to a forward packet.
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz
+        --slcore
+        --plcores
+        --wlcores
+        --stlist (Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+        --nb_flows
+        --nb_pkts
+        --worker_deq_depth
+        --fwd_latency
+        --queue_priority

+   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
+        --plcores
+        --wlcores
+        --stlist (Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+        --nb_flows
+        --nb_pkts
+        --worker_deq_depth
+        --fwd_latency
+
+Example

The master core(!worker core) reads w->latency and

Nice work here - and a good idea to ensure standard tests can be performed against all PMDs.
I'll reply to a few patchset with particulars, in general this looks good to me.

General Note: Not a criticism of this patch;

We seem to be re-writing test-frameworks multiple times, due to lack of external test framework being integrated in DPDK. Mature test frameworks are available that would lighten the work required to achieve this..

One suggestion below to increase the enqueue depth, or was there a reason set it to 8?

No specific reason. I think, In some example, SW driver was configuring to 8.
So I choose to select 8. I will change to 32 as you suggested.

We should forward events for longer than one second. From a SW PMD perspective, it takes some time for caches to warm up, so running a test for 1 second isn't very representative. Suggestion of running default 5 seconds, as a balance between consistent performance and keeping the test runs short?

I'm aware of the --nb_pkts=X arg, this is more about solid defaults :)

There is --plcores (note the added "S") just below. Should standardize to one. Double check with the app - I had some issues with plcore(s) not working as expected.

I think "--nb_pkts" is the correct string, not "packets"?

I think this "(Valid ..)" comment should be on --slcore, not on --stlist?

--slcore being scheduler lcore, and --stlist being the list of queues?

I've posted explicit Acks on a few patches with comments, but apart from that I'll ack Series here. Nice work - a good addition to eventdev infrastructure!

I think "queue_order" isn't a valid test name, we should probably make the default test to run something that is supported by all PMDs, performance testing of atomic traffic?

With that resolved,

The above line is quite long and doesn't render very well in the docs.
Better to do something like:

   sudo build/app/dpdk-test-eventdev --vdev=event_octeontx -- \
                                     --test=order_atq --plcore 1 --wlcores 2,3

[dpdk-dev] [PATCH v2 00/34] introduce generic eventdev test application framework

[Jerin Jacob]

The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK)
application that allows exercising various eventdev use cases. This
application has a generic framework to add new eventdev based test cases
to verify functionality and measure the performance parameters of DPDK
eventdev devices.

This patch set adds the infrastructure for the generic eventdev test cases
framework with four test cases.

1)perf_queue: test to measure the throughput and forward latency of eventdev
pipeline on different PMDs
2)perf_atq: functionally same as perf_queue. But using "all type queues"
eventdev infrastructure
3)order_queue: test to verify the ingress event ordering and atomic
schedule type
4)order_atq: functionally same as order_queue. But using "all types queues"
eventdev infrastructure.

The tests are verified using both HW(OCTEONTX) and SW eventdev PMDs.

We need minor changes in the API specification to run this test cases on HW PMD.
I will send those patches separately.

Since "all type queues" is not currently supported in SW implementation.
"All types queue" based tests returns "unsupported" on SW PMD.

Added detailed documentation for test operation and usage with diagrams in the
last five patches in the series.


v2:

1) Fix s/capablity/capability/g (Gage)
2) Fix the default testcase(Changed to "order_queue")(Harry)
3) Changed default .enqueue_depth = 8 to .enqueue_depth = 32(Harry)
4) Fix s/remining/remaining/g(Harry)
5) Change the default value of nb_pkts to 64M(Harry)
6) s/downsteam/downstream/(John)
7) Fix incorrect reference to --nb_packets in testeventdev.rst(Harry)
8) Fix line wrap in example application commands(John)
9) Enhance the write up on the nb_ports computation logic in testeventdev.rst(Gage)
10) Fix invalid reference to "(Valid ..)" comment(was pointing to --stlist)(Harry)
11) Used RTE_EVENT_DEV_CAP_BURST_MODE to detect the burst mode
capability and fixed the reference to /* FIXME: probe through device capability */(Jerin)
12) Fix duplicate entries in lcore list(Prathyusha)
13) Removed --plcore and reused --plcores option(Harry)
14) Added support for --nb_pkts = 0(0 implies no limit)(Jerin)
15) Added Harry's Series Ack
16) Updated the release notes(Jerin)

[dpdk-dev] [PATCH v2 04/34] app/testeventdev: add string parsing helpers

[Jerin Jacob]

From: Guduri Prathyusha <gprathyusha@caviumnetworks.com>

Add a couple of help functions that will allow parsing many types of
input parameters, i.e.: bool, 16, 32, 64 bits, hex and list of cores etc.

Derived from examples/ip_pipeline/parser.h

[dpdk-dev] [PATCH v2 16/34] app/testeventdev: add order queue test

[Jerin Jacob]

The order queue test configures the eventdev with two queues
and an event producer to inject the events to q0(ordered) queue.
Both q0(ordered) and q1(atomic) are linked to all the workers.

The event producer maintains a sequence number per flow and
injects the events to the ordered queue.

The worker receives the events from ordered queue and
forwards to atomic queue. Since the events from an ordered queue can
be processed in parallel on the different workers, the
ingress order of events might have changed on the downsteam
atomic queue enqueue. On enqueue to the atomic queue, the eventdev PMD
driver reorders the event to the original ingress order
i.e producer ingress order).

When the event is dequeued from the atomic queue by the worker,
this test verifies the expected
sequence number of associated event per flow by comparing
the free running expected sequence number per flow.

Example command to run order queue test:

sudo build/app/dpdk-test-eventdev --vdev=event_sw0 --\
--test=order_queue --plcores 1 --wlcores 2,3

[dpdk-dev] [PATCH v2 18/34] app/testeventdev: add order "all types queue" test

[Jerin Jacob]

This test verifies the same aspects of order_queue test,
The difference is the number of queues used, this test
operates on a single "all types queue"(atq) instead of two
different queues for ordered and atomic.

Example command to run order all types queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=order_atq --plcores 1 --wlcores 2,3

[dpdk-dev] [PATCH v2 19/34] app/testeventdev: perf: add test setup and destroy

[Jerin Jacob]

perf test has the queue and all types queue variants.
Introduce test_perf_common* to share the common code between those tests.

[dpdk-dev] [PATCH v2 23/34] app/testeventdev: perf: launch lcores

[Jerin Jacob]

The event producer and master lcore's test termination and
the logic to print the mpps and latency are common for the
queue and all types queue test.

Move them as the common function.

[dpdk-dev] [PATCH v2 24/34] app/testeventdev: add perf queue test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The perf queue test configures the eventdev with Q queues and P ports,
where Q is nb_producers * nb_stages and P is nb_workers + nb_producers.

The user can choose the number of workers, the number of producers and
number of stages through the --wlcores , --plcores and the --stlist
application command line arguments respectively.

The producer(s) injects the events to eventdev based the
first stage sched type list requested by the user through --stlist
the command line argument.

Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and
terminates when it reaches the last stage in the pipeline.
On event termination, application increments the number events
processed and print periodically in one second to get the
number of events processed in one second.

When --fwd_latency command line option selected, the application
inserts the timestamp in the event on the first stage and then
on termination, it updates the number of cycles to forward
a packet. The application uses this value to compute the average
latency to a forward packet.

Example command to run perf queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- --test=perf_queue\
--slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

[dpdk-dev] [PATCH v2 26/34] app/testeventdev: add perf "all types queue" test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

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.

Example command to run perf "all types queue" test:

sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

+
+dpdk-test-eventdev Application
+==============================
+
+The ``dpdk-test-eventdev`` tool is a Data Plane Development Kit (DPDK)
+application that allows exercising various eventdev use cases.
+This application has a generic framework to add new eventdev based test cases to
+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
+-----------------------
+
+The application has a number of command line options:
+
+.. code-block:: console
+
+   dpdk-test-eventdev [EAL Options] -- [application options]
+
+EAL Options
+~~~~~~~~~~~
+
+The following are the EAL command-line options that can be used in conjunction
+with the ``dpdk-test-eventdev`` application.
+See the DPDK Getting Started Guides for more information on these options.
+
+*   ``-c <COREMASK>`` or ``-l <CORELIST>``
+
+        Set the hexadecimal bitmask of the cores to run on. The corelist is a
+        list of cores to use.
+
+*   ``--vdev <driver><id>``
+
+        Add a virtual eventdev device.
+
+Application Options
+~~~~~~~~~~~~~~~~~~~
+
+The following are the application command-line options:
+
+* ``--verbose``
+
+        Set verbose level. Default is 1. Value > 1 displays more details.
+
+* ``--dev <n>``
+
+        Set the device id of the event device.
+
+* ``--test <name>``
+
+        Set test name, where ``name`` is one of the following::
+
+         order_queue
+         order_atq
+         perf_queue
+         perf_atq
+
+* ``--socket_id <n>``
+
+        Set the socket id of the application resources.
+
+* ``--pool-sz <n>``
+
+        Set the number of mbufs to be allocated from the mempool.
+
+* ``--slcore <n>``
+
+        Set the scheduler lcore id.(Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+
+* ``--plcores <CORELIST>``
+
+        Set the list of cores to be used as producers.
+
+* ``--wlcores <CORELIST>``
+
+        Set the list of cores to be used as workers.
+
+* ``--stlist <type_list>``
+
+        Set the scheduled type of each stage where ``type_list`` size
+        determines the number of stages used in the test application.
+        Each type_list member can be one of the following::
+
+            P or p : Parallel schedule type
+            O or o : Ordered schedule type
+            A or a : Atomic schedule type
+
+        Application expects the ``type_list`` in comma separated form (i.e. ``--stlist o,a,a,a``)
+
+* ``--nb_flows <n>``
+
+        Set the number of flows to produce.
+
+* ``--nb_pkts <n>``
+
+        Set the number of packets to produce. 0 implies no limit.
+
+* ``--worker_deq_depth <n>``
+
+        Set the dequeue depth of the worker.
+
+* ``--fwd_latency``
+
+        Perform forward latency measurement.
+
+* ``--queue_priority``
+
+        Enable queue priority.
+

+   order queue test operation.
+
+The order queue test configures the eventdev with two queues and an event
+producer to inject the events to q0(ordered) queue. Both q0(ordered) and
+q1(atomic) are linked to all the workers.
+
+The event producer maintains a sequence number per flow and injects the events
+to the ordered queue. The worker receives the events from ordered queue and
+forwards to atomic queue. Since the events from an ordered queue can be
+processed in parallel on the different workers, the ingress order of events
+might have changed on the downstream atomic queue enqueue. On enqueue to the
+atomic queue, the eventdev PMD driver reorders the event to the original
+ingress order(i.e producer ingress order).
+
+When the event is dequeued from the atomic queue by the worker, this test
+verifies the expected sequence number of associated event per flow by comparing
+the free running expected sequence number per flow.
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+   --verbose
+   --dev
+   --test
+   --socket_id
+   --pool_sz
+   --plcores
+   --wlcores
+   --nb_flows
+   --nb_pkts
+   --worker_deq_depth
+
+Example
+^^^^^^^
+
+Example command to run order queue test:
+
+.. code-block:: console
+
+   sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- \
+                --test=order_queue --plcores 1 --wlcores 2,3

+
+   perf queue test operation.
+
+The perf queue test configures the eventdev with Q queues and P ports, where
+Q and P is a function of the number of workers, the number of producers and
+number of stages as mentioned in :numref:`table_eventdev_perf_queue_test`.
+
+The user can choose the number of workers, the number of producers and number of
+stages through the ``--wlcores``, ``--plcores`` and the ``--stlist`` application
+command line arguments respectively.
+
+The producer(s) injects the events to eventdev based the first stage sched type
+list requested by the user through ``--stlist`` the command line argument.
+
+Based on the number of stages to process(selected through ``--stlist``),
+The application forwards the event to next upstream queue and terminates when it
+reaches the last stage in the pipeline. On event termination, application
+increments the number events processed and print periodically in one second
+to get the number of events processed in one second.
+
+When ``--fwd_latency`` command line option selected, the application inserts
+the timestamp in the event on the first stage and then on termination, it
+updates the number of cycles to forward a packet. The application uses this
+value to compute the average latency to a forward packet.
+
+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
+        --queue_priority
+
+Example
+^^^^^^^
+
+Example command to run perf queue test:
+
+.. code-block:: console
+
+   sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- \
+        --test=perf_queue --slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=0

+
+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.

[dpdk-dev] [PATCH v3 00/34] introduce generic eventdev test application framework

[Jerin Jacob]

The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK)
application that allows exercising various eventdev use cases. This
application has a generic framework to add new eventdev based test cases
to verify functionality and measure the performance parameters of DPDK
eventdev devices.

This patch set adds the infrastructure for the generic eventdev test cases
framework with four test cases.

1)perf_queue: test to measure the throughput and forward latency of eventdev
pipeline on different PMDs
2)perf_atq: functionally same as perf_queue. But using "all type queues"
eventdev infrastructure
3)order_queue: test to verify the ingress event ordering and atomic
schedule type
4)order_atq: functionally same as order_queue. But using "all types queues"
eventdev infrastructure.

The tests are verified using both HW(OCTEONTX) and SW eventdev PMDs.

We need minor changes in the API specification to run this test cases on HW PMD.
I will send those patches separately.

Since "all type queues" is not currently supported in SW implementation.
"All types queue" based tests returns "unsupported" on SW PMD.

Added detailed documentation for test operation and usage with diagrams in the
last five patches in the series.

v3:

1) Cleaned up the license header in app/test-eventdev/parser.c
The following two proprietary headers were removed as inet_pton4(),
inet_pton4(), my_ether_aton() has not been used.

+/*
+ * For my_ether_aton() function:
+ *
+ * Copyright (c) 2009, Olivier MATZ <zer0@droids-corp.org>

+/*
+ * For inet_pton4() and inet_pton6() functions:
+ *
+ * Copyright (c) 1996 by Internet Software Consortium.

v2:

1) Fix s/capablity/capability/g (Gage)
2) Fix the default testcase(Changed to "order_queue")(Harry)
3) Changed default .enqueue_depth = 8 to .enqueue_depth = 32(Harry)
4) Fix s/remining/remaining/g(Harry)
5) Change the default value of nb_pkts to 64M(Harry)
6) s/downsteam/downstream/(John)
7) Fix incorrect reference to --nb_packets in testeventdev.rst(Harry)
8) Fix line wrap in example application commands(John)
9) Enhance the write up on the nb_ports computation logic in testeventdev.rst(Gage)
10) Fix invalid reference to "(Valid ..)" comment(was pointing to --stlist)(Harry)
11) Used RTE_EVENT_DEV_CAP_BURST_MODE to detect the burst mode
capability and fixed the reference to /* FIXME: probe through device capability */(Jerin)
12) Fix duplicate entries in lcore list(Prathyusha)
13) Removed --plcore and reused --plcores option(Harry)
14) Added support for --nb_pkts = 0(0 implies no limit)(Jerin)
15) Added Harry's Series Ack
16) Updated the release notes(Jerin)

[dpdk-dev] [PATCH v3 01/34] app/testeventdev: introduce dpdk-test-eventdev application

[Jerin Jacob]

The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK)
application that allows exercising various eventdev use cases. This
application has a generic framework to add new eventdev based test cases
to verify functionality and measure the performance parameters of DPDK
eventdev devices.

This patch adds the skeleton of the dpdk-test-eventdev application.

[dpdk-dev] [PATCH v3 16/34] app/testeventdev: add order queue test

[Jerin Jacob]

The order queue test configures the eventdev with two queues
and an event producer to inject the events to q0(ordered) queue.
Both q0(ordered) and q1(atomic) are linked to all the workers.

The event producer maintains a sequence number per flow and
injects the events to the ordered queue.

The worker receives the events from ordered queue and
forwards to atomic queue. Since the events from an ordered queue can
be processed in parallel on the different workers, the
ingress order of events might have changed on the downsteam
atomic queue enqueue. On enqueue to the atomic queue, the eventdev PMD
driver reorders the event to the original ingress order
i.e producer ingress order).

When the event is dequeued from the atomic queue by the worker,
this test verifies the expected
sequence number of associated event per flow by comparing
the free running expected sequence number per flow.

Example command to run order queue test:

sudo build/app/dpdk-test-eventdev --vdev=event_sw0 --\
--test=order_queue --plcores 1 --wlcores 2,3

[dpdk-dev] [PATCH v3 18/34] app/testeventdev: add order "all types queue" test

[Jerin Jacob]

This test verifies the same aspects of order_queue test,
The difference is the number of queues used, this test
operates on a single "all types queue"(atq) instead of two
different queues for ordered and atomic.

Example command to run order all types queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=order_atq --plcores 1 --wlcores 2,3

[dpdk-dev] [PATCH v3 19/34] app/testeventdev: perf: add test setup and destroy

[Jerin Jacob]

perf test has the queue and all types queue variants.
Introduce test_perf_common* to share the common code between those tests.

[dpdk-dev] [PATCH v3 23/34] app/testeventdev: perf: launch lcores

[Jerin Jacob]

The event producer and master lcore's test termination and
the logic to print the mpps and latency are common for the
queue and all types queue test.

Move them as the common function.

[dpdk-dev] [PATCH v3 24/34] app/testeventdev: add perf queue test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The perf queue test configures the eventdev with Q queues and P ports,
where Q is nb_producers * nb_stages and P is nb_workers + nb_producers.

The user can choose the number of workers, the number of producers and
number of stages through the --wlcores , --plcores and the --stlist
application command line arguments respectively.

The producer(s) injects the events to eventdev based the
first stage sched type list requested by the user through --stlist
the command line argument.

Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and
terminates when it reaches the last stage in the pipeline.
On event termination, application increments the number events
processed and print periodically in one second to get the
number of events processed in one second.

When --fwd_latency command line option selected, the application
inserts the timestamp in the event on the first stage and then
on termination, it updates the number of cycles to forward
a packet. The application uses this value to compute the average
latency to a forward packet.

Example command to run perf queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- --test=perf_queue\
--slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

[dpdk-dev] [PATCH v3 26/34] app/testeventdev: add perf "all types queue" test

[Jerin Jacob]

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

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.

Example command to run perf "all types queue" test:

sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

+
+dpdk-test-eventdev Application
+==============================
+
+The ``dpdk-test-eventdev`` tool is a Data Plane Development Kit (DPDK)
+application that allows exercising various eventdev use cases.
+This application has a generic framework to add new eventdev based test cases to
+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
+-----------------------
+
+The application has a number of command line options:
+
+.. code-block:: console
+
+   dpdk-test-eventdev [EAL Options] -- [application options]
+
+EAL Options
+~~~~~~~~~~~
+
+The following are the EAL command-line options that can be used in conjunction
+with the ``dpdk-test-eventdev`` application.
+See the DPDK Getting Started Guides for more information on these options.
+
+*   ``-c <COREMASK>`` or ``-l <CORELIST>``
+
+        Set the hexadecimal bitmask of the cores to run on. The corelist is a
+        list of cores to use.
+
+*   ``--vdev <driver><id>``
+
+        Add a virtual eventdev device.
+
+Application Options
+~~~~~~~~~~~~~~~~~~~
+
+The following are the application command-line options:
+
+* ``--verbose``
+
+        Set verbose level. Default is 1. Value > 1 displays more details.
+
+* ``--dev <n>``
+
+        Set the device id of the event device.
+
+* ``--test <name>``
+
+        Set test name, where ``name`` is one of the following::
+
+         order_queue
+         order_atq
+         perf_queue
+         perf_atq
+
+* ``--socket_id <n>``
+
+        Set the socket id of the application resources.
+
+* ``--pool-sz <n>``
+
+        Set the number of mbufs to be allocated from the mempool.
+
+* ``--slcore <n>``
+
+        Set the scheduler lcore id.(Valid when eventdev is not RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capable)
+
+* ``--plcores <CORELIST>``
+
+        Set the list of cores to be used as producers.
+
+* ``--wlcores <CORELIST>``
+
+        Set the list of cores to be used as workers.
+
+* ``--stlist <type_list>``
+
+        Set the scheduled type of each stage where ``type_list`` size
+        determines the number of stages used in the test application.
+        Each type_list member can be one of the following::
+
+            P or p : Parallel schedule type
+            O or o : Ordered schedule type
+            A or a : Atomic schedule type
+
+        Application expects the ``type_list`` in comma separated form (i.e. ``--stlist o,a,a,a``)
+
+* ``--nb_flows <n>``
+
+        Set the number of flows to produce.
+
+* ``--nb_pkts <n>``
+
+        Set the number of packets to produce. 0 implies no limit.
+
+* ``--worker_deq_depth <n>``
+
+        Set the dequeue depth of the worker.
+
+* ``--fwd_latency``
+
+        Perform forward latency measurement.
+
+* ``--queue_priority``
+
+        Enable queue priority.

+   order queue test operation.
+
+The order queue test configures the eventdev with two queues and an event
+producer to inject the events to q0(ordered) queue. Both q0(ordered) and
+q1(atomic) are linked to all the workers.
+
+The event producer maintains a sequence number per flow and injects the events
+to the ordered queue. The worker receives the events from ordered queue and
+forwards to atomic queue. Since the events from an ordered queue can be
+processed in parallel on the different workers, the ingress order of events
+might have changed on the downstream atomic queue enqueue. On enqueue to the
+atomic queue, the eventdev PMD driver reorders the event to the original
+ingress order(i.e producer ingress order).
+
+When the event is dequeued from the atomic queue by the worker, this test
+verifies the expected sequence number of associated event per flow by comparing
+the free running expected sequence number per flow.
+

+ORDER_ATQ Test
+~~~~~~~~~~~~~~
+
+This test verifies the same aspects of ``order_queue`` test, the difference is
+the number of queues used, this test operates on a single ``all types queue(atq)``
+instead of two different queues for ordered and atomic.

+   perf queue test operation.
+
+The perf queue test configures the eventdev with Q queues and P ports, where
+Q and P is a function of the number of workers, the number of producers and
+number of stages as mentioned in :numref:`table_eventdev_perf_queue_test`.
+
+The user can choose the number of workers, the number of producers and number of
+stages through the ``--wlcores``, ``--plcores`` and the ``--stlist`` application
+command line arguments respectively.
+
+The producer(s) injects the events to eventdev based the first stage sched type
+list requested by the user through ``--stlist`` the command line argument.
+
+Based on the number of stages to process(selected through ``--stlist``),
+The application forwards the event to next upstream queue and terminates when it
+reaches the last stage in the pipeline. On event termination, application
+increments the number events processed and print periodically in one second
+to get the number of events processed in one second.
+
+When ``--fwd_latency`` command line option selected, the application inserts
+the timestamp in the event on the first stage and then on termination, it
+updates the number of cycles to forward a packet. The application uses this
+value to compute the average latency to a forward packet.
+
+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
+        --queue_priority
+

+   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
+^^^^^^^
+
+Example command to run perf ``all types queue`` test:
+
+.. code-block:: console
+
+   sudo build/app/dpdk-test-eventdev --vdev=event_octeontx -- \
+                --test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=0
