Sat Dec 23 01:52:10 CET 2017


- sample application performing a loop-back over ethernet using
 a bbbdev device
- 'turbo_sw' PMD must be enabled for the app to be functional
- a packet is received on an ethdev port -> enqueued for baseband
 encode operation -> dequeued -> enqueued for baseband decode
 operation-> dequeued -> compared with original signal -> looped-back
 to the ethdev port

+Loop-back Sample Application using Baseband Device (bbdev)
+==========================================================
+
+The baseband sample application is a simple example of packet processing using
+the Data Plane Development Kit (DPDK) for baseband workloads using Wireless
+Device abstraction library.
+
+Overview
+--------
+
+The Baseband device sample application performs a loop-back operation using a
+baseband device capable of transceiving data packets.
+A packet is received on an ethernet port -> enqueued for downlink baseband
+operation -> dequeued from the downlink baseband device -> enqueued for uplink
+baseband operation -> dequeued from the baseband device -> then the received
+packet is compared with the baseband operations output. Then it's looped back to
+the ethernet port.
+
+*   The MAC header is preserved in the packet
+
+Limitations
+-----------
+
+* Only one baseband device and one ethernet port can be used.
+
+Compiling the Application
+-------------------------
+
+#. DPDK needs to be built with ``turbo_sw`` PMD driver enabled along with
+   ``FLEXRAN SDK`` Libraries. Refer to *SW Turbo Poll Mode Driver*
+   documentation for more details on this.
+
+#. Go to the example directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SDK}/examples/bbdev_app
+
+#. Set the target (a default target is used if not specified). For example:
+
+    .. code-block:: console
+
+        export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+    See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#. Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the Application
+-----------------------
+
+The application accepts a number of command line options:
+
+.. code-block:: console
+
+    $ ./build/bbdev [EAL options] -- [-e ENCODING_CORES] [-d DECODING_CORES] /
+    [-p ETH_PORT_ID] [-b BBDEV_ID]
+
+where:
+
+* ``e ENCODING_CORES``: hexmask for encoding lcored (default = 0x2)
+* ``d DECODING_CORES``: hexmask for decoding lcores (default = 0x4)
+* ``p ETH_PORT_ID``: ethernet port ID (default = 0)
+* ``b BBDEV_ID``: BBDev ID (default = 0)
+
+The application requires that baseband devices is capable of performing
+the specified baseband operation are available on application initialization.
+This means that HW baseband device/s must be bound to a DPDK driver or
+a SW baseband device/s (virtual BBdev) must be created (using --vdev).
+
+To run the application in linuxapp environment with the turbo_sw baseband device
+using the whitelisted port running on 1 encoding lcore and 1 decoding lcore
+issue the command:
+
+.. code-block:: console
+
+    $ ./build/bbdev --vdev='turbo_sw' -w <NIC0PCIADDR> -c 0x38 --socket-mem=2,2 \
+    --file-prefix=bbdev -- -e 0x10 -d 0x20
+
+where, NIC0PCIADDR is the PCI addresse of the Rx port
+
+This command creates one virtual bbdev devices ``turbo_sw`` where the device
+gets linked to a corresponding ethernet port as whitelisted by the parameter -w.
+3 cores are allocated to the application, and assigned as:
+
+ - core 3 is the master and used to print the stats live on screen,
+
+ - core 4 is the encoding lcore performing Rx and Turbo Encode operations
+
+ - core 5 is the downlink lcore performing Turbo Decode, validation and Tx
+   operations
+
+
+Refer to the *DPDK Getting Started Guide* for general information on running
+applications and the Environment Abstraction Layer (EAL) options.
+
+Using Packet Generator with baseband device sample application
+--------------------------------------------------------------
+
+To allow the bbdev sample app to do the loopback, an influx of traffic is required.
+This can be done by using DPDK Pktgen to burst traffic on two ethernet ports, and
+it will print the transmitted along with the looped-back traffic on Rx ports.
+Executing the command below will generate traffic on the two whitelisted ethernet
+ports.
+
+.. code-block:: console
+
+    $ ./pktgen-3.4.0/app/x86_64-native-linuxapp-gcc/pktgen -c 0x3 \
+    --socket-mem=1,1 --file-prefix=pg -w <NIC1PCIADDR> -- -m 1.0 -P
+
+where:
+
+* ``-c COREMASK``: A hexadecimal bitmask of cores to run on
+* ``--socket-mem``: Memory to allocate on specific sockets (use comma separated values)
+* ``--file-prefix``: Prefix for hugepage filenames
+* ``-w <NIC1PCIADDR>``: Add a PCI device in white list. The argument format is <[domain:]bus:devid.func>.
+* ``-m <string>``: Matrix for mapping ports to logical cores.
+* ``-P``: PROMISCUOUS mode
+
+
+Refer to *The Pktgen Application* documents for general information on running
+Pktgen with DPDK applications.
