This is a performance test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The perf pipeline test configures the eventdev with Q queues and P ports,
where Q is nb_ethdev * nb_stages and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run perf pipeline test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=perf_pipeline --wlcore=1 --prod_type_ethdev --stlist=ao

+
+   perf pipeline test operation.
+
+The perf pipeline 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_pipeline_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.
+
+    .. Note::
+
+      * If the event device doesn't support ``all types queue`` and the last
+        stage is not ``atomic`` then an additional ``atomic`` queue is created
+        to maintain packet ordering before Tx.
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz
+        --wlcores
+        --stlist
+        --worker_deq_depth
+        --prod_type_ethdev
+
+
+.. Note::
+
+    * The ``--prod_type_ethdev`` is mandatory for running this test.
+
+Example

+
+Example command to run perf pipeline test:

For the hard-coded event device (new_event_threshold, port_dequeue_depth, enqueue_depth) and port configuration (enqueue_depth, new_event_threshold) values, it would be better to use the values from rte_event_dev_info_get() and rte_event_port_default_conf_get() instead.

Thanks,
Gage

atq support is not available in sw driver. So please rework
this test to make separate fast path functions for queue and
atq like other performance tests in this directory.
This will further reduce the complexity in fast path and
Please split the files also to depict the model.Something like,

test_perf_pipeline_common.c
test_perf_pipeline_queue.c
test_perf_pipeline_atq.c

Agreed, but the name seems too long would test_pipeline_* be acceptable?

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

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

+   pipeline queue test operation.
+
+The pipeline 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_pipeline_queue_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.
+
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz

+        --worker_deq_depth
+        --prod_type_ethdev
+
+
+.. Note::
+
+    * The ``--prod_type_ethdev`` is mandatory for running this test.

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

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

 v3 Changes:
 - redo queue creation by changing the queue count to nb_ethdev
 - add SPDX licence tags

Why (nb_ethdev * nb_stages) number of Queues?

I had expected if the test is for eventdev with Q queues, P ports, that that Q number of stages is all that is required, (possibly with +1 for TX queue, iirc some HW doesn't require the TX Queue).

Am I missing something here? I've left the code snippet I don't understand below.

Mandatory arguments seem pointless to me, unless there are other valid options to choose from.

As per comment above, this is what I don't understand? Why more queues than stages?

IIRC usually the "Safe" version of a function has extra locks/protection, while the "normal" version has better performance, but less-error-checking.

Here, the "unsafe" function does the extra locking. If looking from the HW POV, that makes sense, but I think its inverted from most existing code...

Happy to be proved wrong here .. ?

I guess that means that the functions where they're used are inverted in name too.

Thinking a little more about this, also in light of patch 11/12 of this series.

The code here has a "safe" and "unsafe" version of TX. This involves adding a spinlock inside the code, which is being locked/unlocked before doing the actual TX action.

I don't understand why this is necessary? DPDK's general stance on locking for data-path is DPDK functions do not provide locks, and that application level must implement thread-synchronization if it is required.

In this case, the app/eventdev can be considered an App, but I don't like the idea of providing a sample application and code that duplicates core functionality with safe/unsafe versions..

Hope I'm making some sense here..

Hi Harry,

Thanks for the review.

The idea is to reduce the load on ingress event queue (mapped to ethernet Rx queue)
by splitting the traffic across event queues for each ethernet device.

for example, nb_stages =  2 and nb_ethdev = 2 then

	nb_queues = (2 * 2) + 2 = 6 (non atq)
	stride = 3 (nb_stages + 1 used for directing each ethernet dev traffic
			into a specific event queue)

queue id's 0,1,2,3,4,5

This allows us to direct the traffic from eth dev0 to event queue 0 and dev1 to
queue 3 based on the stride (dev_id * stride). This intern forms two pipelines
	ethdev0	0->1->2->tx
	ethdev1	3->4->5->tx

In the absence of this both  ethdev0 and ethdev1 would have to inject to 0th
queue and this leads to more congestion as the number of ethernet devices
increase.

Hope this clears things up.

Some PMD's (net/octeontx) have capability to do multi-thread safe Tx where no
thread-synchronization is required. This is exposed via the offload flag
'DEV_TX_OFFLOAD_MT_LOCKFREE'.

So, the _safe Tx functions are selected based on the above offload capability
and when the capability is absent _unsafe Tx functions are selected i.e.
synchronized Tx via spin locks based on the Egress port id.

The patch 5/12 has the below check to see if the connected ethernet dev(s) have
the capability to do thread safe Tx

+	for (i = 0; i < rte_eth_dev_count(); i++) {
+		struct rte_eth_dev_info dev_info;
....
+		rte_eth_dev_info_get(i, &dev_info);
+		mt_state = !(dev_info.tx_offload_capa &
+				DEV_TX_OFFLOAD_MT_LOCKFREE);
....
+		t->mt_unsafe |= mt_state;
+	}

Based on the value of t->mt_unsafe the appropriate worker function is selected.

This part changes the current behavior of the sample app.

Currently there is a (SINGLE_LINK | ATOMIC) stage at the end of the pipeline, which performs this "many-to-one" action, allowing a single core to dequeue all TX traffic, and perform the TX operation in a lock-free manner.

Changing this to a locking mechanism is going to hurt performance on platforms that do not support TX_OFFLOAD_MT_LOCKFREE.

In my opinion, the correct fix is to alter the overall pipeline, and always use lockless TX. Examples below;

NO TX_OFFLOAD_MT_LOCKFREE:

   Eth RX adapter -> stage 1 -> stage 2...(N-1) -> stage N -> stage TX (Atomic | SINGLE_LINK) -> eth TX


WITH TX_OFFLOAD_MT_LOCKFREE:

   Eth RX adapter -> stage 1 -> stage 2...(N-1) -> stage N -> eth TX MT Capable


By configuring the pipeline based on MT_OFFLOAD_LOCKFREE capability flag, and adding the SINGLE_LINK at the end if required, we can support both models without resorting to locked TX functions.

I think this will lead to a cleaner and more performant solution.

Agreed, when we detect that tx is not lockfree the workers would just forward
the events to  (Atomic | SINGLE_LINK) event queue which would be dequeued by a
service(mt_unsafe) and Tx them lockfree.

The current lockfree pipeline would remain the same.

A quick summary of the issue here, and then an overview of my understanding of the proposed solution.


=== Issue ===
Ethdev hardware has a flag TX_OFFLOAD_MT_LOCKFREE, which when set means that multiple CPU threads can safely TX on a single ethdev-queue concurrently (aka; without locking). Not all hardware supports this, so applications must be able to gracefully handle hardware where this capability is not provided.


=== Solution ===
In eventdev pipelines with MT_LOCKFREE capability, the CPU running the last "worker" stage can also perform the ethdev-TX operation.

In eventdev pipelines without MT_LOCKFREE caps, we use a (Single Link | Atomic) stage to "fan in" the traffic to a single point, and use a TX service in order to abstract away the difference in CPU core requirements.



The above solution avoids placing locks in the datapath by modifying the pipeline design, and the difference in CPU requirements is abstracted by only registering the TX service if required.

Note that the TX service doesn't need the infrastructure like the RX adapter, as it is much simpler (dequeue from eventdev port, tx on ethdev port).


@Pavan, I believe this is the same solution as you - just making sure we're aligned!


Cheers, -Harry

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

Setup one port event port for Tx and link the respective event queue.
Register the Tx function as a service to be called from a service core.
The Tx function dequeues the events from the event queue and transmits
the packet to its respective ethernet port.

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

+   pipeline queue test operation.
+
+The pipeline 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_pipeline_queue_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+
+If the ethernet has ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capability then the worker
+cores transmit the packets directly. Else the worker cores enqueue the packet
+onto the ``SINGLE_LINK_QUEUE`` that is managed by a Tx service. The Tx service
+dequeues the packet and transmits it.
+
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.

Ah ok, two parallel pipelines use-case. Makes sense, thanks for explaining.

Some suggestions in the diagram,
1) In total_queues = equation, Please add some mean full info on the last "number of producers"
2) Have separate diagram for "Tx generic" and "Tx lockfree" case to
understand the follow easily.
3) IMO, The backward arrow towards queue from port(The red one) is may
not depicting the actual flow from the application perspective.
4) Same comments apply for PIPELINE_ATQ diagram

I think, it will be good to say the value of _x_ for MT_LOCKFREE vs non MT_LOCKFREE case

Another than above comments, It looks good to me.

It looks like the code above never sets the "component runstate" to indicate that the TX service itself is in a runnable state.

This setting of the runstate is performed later in the setup process, when launching cores.

Some of the code feels like duplication - but there are differences in each implementation as far as I can see. The common initialization parts are "macro-ed" to ensure minimal duplication. In short, I'm not aware of a better solution/implementation.

Please see note on branch-optimization in the code below.

I don't think the compiler will optimize the below, as the nb_stages value comes from opt, which is a uint8 originating from a pointer-dereference... 

As far as I know, an optimizing compiler will do "constant propagation" through function calls, but I would be amazed if it found a pointer initialized to a specific value, and optimized the branches away here based on the contents of that pointer deref.

So I see 2 options;
1) accept as is - I'll ack this patch here
2) Rework so that the worker_wrapper() accepts nb_stages, burst and mt_safe as function arguments, allowing constant propagation for optimizing away the branches.

@Pavan, I'll leave that choice up to you!

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

Setup one port event port for Tx and link the respective event queue.
Register the Tx function as a service to be called from a service core.
The Tx function dequeues the events from the event queue and transmits
the packet to its respective ethernet port.

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

+
+   pipeline queue test operation.
+
+The pipeline 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_pipeline_queue_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+
+If the ethernet has ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capability then the worker
+cores transmit the packets directly. Else the worker cores enqueue the packet
+onto the ``SINGLE_LINK_QUEUE`` that is managed by a Tx service. The Tx service
+dequeues the packet and transmits it.
+
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.
+
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz
+        --wlcores
+        --stlist
+        --worker_deq_depth
+        --prod_type_ethdev
+
+
+.. Note::
+
+    * The ``--prod_type_ethdev`` is mandatory for running this test.

+The pipeline atq test configures the eventdev with Q queues and P ports,

+
+The atq queue test functions as same as ``pipeline_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.

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

Setup one port event port for Tx and link the respective event queue.
Register the Tx function as a service to be called from a service core.
The Tx function dequeues the events from the event queue and transmits
the packet to its respective ethernet port.

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

+   pipeline queue test operation.
+
+The pipeline 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_pipeline_queue_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+
+If the ethernet has ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capability then the worker
+cores transmit the packets directly. Else the worker cores enqueue the packet
+onto the ``SINGLE_LINK_QUEUE`` that is managed by a Tx service. The Tx service
+dequeues the packet and transmits it.
+
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.
+
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test

+        --pool_sz
+        --wlcores
+        --stlist
+        --worker_deq_depth
+        --prod_type_ethdev
+
+
+.. Note::
+
+    * The ``--prod_type_ethdev`` is mandatory for running this test.

+
+The atq queue test functions as same as ``pipeline_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.

Setup one port event port for Tx and link the respective event queue.
Register the Tx function as a service to be called from a service core.
The Tx function dequeues the events from the event queue and transmits
the packet to its respective ethernet port.

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

Move them as the common function.

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule 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 when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao

This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_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.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao

+
+   pipeline queue test operation.
+
+The pipeline 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_pipeline_queue_test`.
+
+The user can choose the number of workers and number of stages through the
+``--wlcores`` and the ``--stlist`` application command line arguments
+respectively.
+
+The number of producers depends on the number of ethernet devices detected and
+each ethernet device is configured as a event_eth_rx_adapter that acts as a
+producer.
+
+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 when it reaches
+the last stage in the pipeline if the event type is ``atomic`` it is enqueued
+onto ethdev Tx queue else to maintain ordering the event type is set to
+``atomic`` and enqueued onto the last stage queue.
+
+If the ethernet has ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capability then the worker
+cores transmit the packets directly. Else the worker cores enqueue the packet
+onto the ``SINGLE_LINK_QUEUE`` that is managed by a Tx service. The Tx service
+dequeues the packet and transmits it.
+
+On packet Tx, application increments the number events processed and print
+periodically in one second to get the number of events processed in one
+second.
+
+
+Application options
+^^^^^^^^^^^^^^^^^^^
+
+Supported application command line options are following::
+
+        --verbose
+        --dev
+        --test
+        --socket_id
+        --pool_sz
+        --wlcores
+        --stlist
+        --worker_deq_depth
+        --prod_type_ethdev
+
+
+.. Note::
+
+    * The ``--prod_type_ethdev`` is mandatory for running this test.
+
+Example
+^^^^^^^
+
+Example command to run pipeline queue test:
+
+.. code-block:: console
+
+    sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
+        --test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=a

+   pipeline atq test operation.
+
+The pipeline atq 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_pipeline_atq_test`.
+
+The atq queue test functions as same as ``pipeline_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.
