+Wireless Baseband Device Library
+================================
+
+The Wireless Baseband library provides a common programming framework that
+abstracts HW accelerators based on FPGA and/or Fixed Function Accelerators that
+assist with 3gpp Physical Layer processing. Furthermore, it decouples the
+application from the compute-intensive wireless functions by abstracting their
+optimized libraries to appear as virtual bbdev devices.
+
+The functional scope of the BBDEV library are those functions in relation to
+the 3gpp Layer 1 signal processing (channel coding, modulation, ...).
+
+The framework currently only supports Turbo Code FEC function.
+
+
+Design Principles
+-----------------
+
+The Wireless Baseband library follows the same ideology of DPDK's Ethernet
+Device and Crypto Device frameworks. Wireless Baseband provides a generic
+acceleration abstraction framework which supports both physical (hardware) and
+virtual (software) wireless acceleration functions.
+
+Device Management
+-----------------
+
+Device Creation
+~~~~~~~~~~~~~~~
+
+Physical bbdev devices are discovered during the PCI probe/enumeration of the
+EAL function which is executed at DPDK initialization, based on
+their PCI device identifier, each unique PCI BDF (bus/bridge, device,
+function).
+
+Virtual devices can be created by two mechanisms, either using the EAL command
+line options or from within the application using an EAL API directly.
+
+From the command line using the --vdev EAL option
+
+.. code-block:: console
+
+   --vdev 'turbo_sw,max_nb_queues=8,socket_id=0'
+
+Our using the rte_vdev_init API within the application code.
+
+.. code-block:: c
+
+    rte_vdev_init("turbo_sw", "max_nb_queues=2,socket_id=0")
+
+All virtual bbdev devices support the following initialization parameters:
+
+- ``max_nb_queues`` - maximum number of queues supported by the device.
+
+- ``socket_id`` - socket on which to allocate the device resources on.
+
+
+Device Identification
+~~~~~~~~~~~~~~~~~~~~~
+
+Each device, whether virtual or physical is uniquely designated by two
+identifiers:
+
+- A unique device index used to designate the bbdev device in all functions
+  exported by the bbdev API.
+
+- A device name used to designate the bbdev device in console messages, for
+  administration or debugging purposes. For ease of use, the port name includes
+  the port index.
+
+
+Device Configuration
+~~~~~~~~~~~~~~~~~~~~
+
+From the application point of view, each instance of a bbdev device consists of
+one or more queues identified by queue IDs. While different devices may have
+different capabilities (e.g. support different operation types), all queues on
+a device support identical configuration possibilities. A queue is configured
+for only one type of operation and is configured at initializations time.
+When an operation is enqueued to a specific queue ID, the result is dequeued
+from the same queue ID.
+
+Configuration of a device has two different levels: configuration that applies
+to the whole device, and configuration that applies to a single queue.
+
+Device configuration is applied with
+``rte_bbdev_setup_queues(dev_id,num_queues,socket_id)``
+and queue configuration is applied with
+``rte_bbdev_queue_configure(dev_id,queue_id,conf)``. Note that, although all
+queues on a device support same capabilities, they can be configured differently
+and will then behave differently.
+Devices supporting interrupts can enable them by using
+``rte_bbdev_intr_enable(dev_id)``.
+
+The configuration of each bbdev device includes the following operations:
+
+- Allocation of resources, including hardware resources if a physical device.
+- Resetting the device into a well-known default state.
+- Initialization of statistics counters.
+
+The ``rte_bbdev_setup_queues`` API is used to setup queues for a bbdev device.
+
+.. code-block:: c
+
+   int rte_bbdev_setup_queues(uint16_t dev_id, uint16_t num_queues,
+            int socket_id);
+
+- ``num_queues`` argument identifies the total number of queues to setup for
+  this device.
+
+- ``socket_id`` specifies which socket will be used to allocate the memory.
+
+
+The ``rte_bbdev_intr_enable`` API is used to enable interrupts for a bbdev
+device, if supported by the driver. Should be called before starting the device.
+
+.. code-block:: c
+
+   int rte_bbdev_intr_enable(uint16_t dev_id);
+
+
+Queues Configuration
+~~~~~~~~~~~~~~~~~~~~
+
+Each bbdev devices queue is individually configured through the
+``rte_bbdev_queue_configure()`` API.
+Each queue resources may be allocated on a specified socket.
+
+.. code-block:: c
+
+    struct rte_bbdev_queue_conf {
+        int socket;
+        uint32_t queue_size;
+        uint8_t priority;
+        bool deferred_start;
+        enum rte_bbdev_op_type op_type;
+    };
+
+Device & Queues Management
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After initialization, devices are in a stopped state, so must be started by the
+application. If an application is finished using a device it can close the
+device. Once closed, it cannot be restarted.
+
+.. code-block:: c
+
+    int rte_bbdev_start(uint16_t dev_id)
+    int rte_bbdev_stop(uint16_t dev_id)
+    int rte_bbdev_close(uint16_t dev_id)
+    int rte_bbdev_queue_start(uint16_t dev_id, uint16_t queue_id)
+    int rte_bbdev_queue_stop(uint16_t dev_id, uint16_t queue_id)
+
+
+By default, all queues are started when the device is started, but they can be
+stopped individually.
+
+.. code-block:: c
+
+    int rte_bbdev_queue_start(uint16_t dev_id, uint16_t queue_id)
+    int rte_bbdev_queue_stop(uint16_t dev_id, uint16_t queue_id)
+
+
+Logical Cores, Memory and Queues Relationships
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The bbdev device Library as the Poll Mode Driver library support NUMA for when
+a processor’s logical cores and interfaces utilize its local memory. Therefore
+baseband operations, the mbuf being operated on should be allocated from memory
+pools created in the local memory. The buffers should, if possible, remain on
+the local processor to obtain the best performance results and buffer
+descriptors should be populated with mbufs allocated from a mempool allocated
+from local memory.
+
+The run-to-completion model also performs better, especially in the case of
+virtual bbdev devices, if the baseband operation and data buffers are in local
+memory instead of a remote processor's memory. This is also true for the
+pipe-line model provided all logical cores used are located on the same processor.
+
+Multiple logical cores should never share the same queue for enqueuing
+operations or dequeuing operations on the same bbdev device since this would
+require global locks and hinder performance. It is however possible to use a
+different logical core to dequeue an operation on a queue pair from the logical
+core which it was enqueued on. This means that a baseband burst enqueue/dequeue
+APIs are a logical place to transition from one logical core to another in a
+packet processing pipeline.
+
+
+Device Operation Capabilities
+-----------------------------
+
+Capabilities (in terms of operations supported, max number of queues, etc.)
+identify what a bbdev is capable of performing that differs from one device to
+another. For the full scope of the bbdev capability see the definition of the
+structure in the *DPDK API Reference*.
+
+.. code-block:: c
+
+   struct rte_bbdev_op_cap;
+
+A device reports its capabilities when registering itself in the bbdev framework.
+With the aid of this capabilities mechanism, an application can query devices to
+discover which operations within the 3gpp physical layer they are capable of
+performing. Below is an example of the capabilities for a PMD it supports in
+relation to Turbo Encoding and Decoding operations.
+
+.. code-block:: c
+
+    static const struct rte_bbdev_op_cap bbdev_capabilities[] = {
+        {
+            .type = RTE_BBDEV_OP_TURBO_DEC,
+            .cap.turbo_dec = {
+                .capability_flags =
+                    RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE |
+                    RTE_BBDEV_TURBO_POS_LLR_1_BIT_IN |
+                    RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN |
+                    RTE_BBDEV_TURBO_CRC_TYPE_24B,
+                .num_buffers_src = RTE_BBDEV_MAX_CODE_BLOCKS,
+                .num_buffers_hard_out =
+                        RTE_BBDEV_MAX_CODE_BLOCKS,
+                .num_buffers_soft_out = 0,
+            }
+        },
+        {
+            .type   = RTE_BBDEV_OP_TURBO_ENC,
+            .cap.turbo_enc = {
+                .capability_flags =
+                        RTE_BBDEV_TURBO_CRC_24B_ATTACH |
+                        RTE_BBDEV_TURBO_RATE_MATCH |
+                        RTE_BBDEV_TURBO_RV_INDEX_BYPASS,
+                .num_buffers_src = RTE_BBDEV_MAX_CODE_BLOCKS,
+                .num_buffers_dst = RTE_BBDEV_MAX_CODE_BLOCKS,
+            }
+        },
+        RTE_BBDEV_END_OF_CAPABILITIES_LIST()
+    };
+
+Capabilities Discovery
+~~~~~~~~~~~~~~~~~~~~~~
+
+Discovering the features and capabilities of a bbdev device poll mode driver
+is achieved through the ``rte_bbdev_info_get()`` function.
+
+.. code-block:: c
+
+   int rte_bbdev_info_get(uint16_t dev_id, struct rte_bbdev_info *dev_info)
+
+This allows the user to query a specific bbdev PMD and get all the device
+capabilities. The ``rte_bbdev_info`` structure provides two levels of
+information:
+
+- Device relevant information, like: name and related rte_bus.
+
+- Driver specific information, as defined by the ``struct rte_bbdev_driver_info``
+  structure, this is where capabilities reside along with other specifics like:
+  maximum queue sizes and priority level.
+
+.. code-block:: c
+
+    struct rte_bbdev_info {
+        int socket_id;
+        const char *dev_name;
+        const struct rte_bus *bus;
+        uint16_t num_queues;
+        bool started;
+        struct rte_bbdev_driver_info drv;
+    };
+
+Operation Processing
+--------------------
+
+Scheduling of baseband operations on DPDK's application data path is
+performed using a burst oriented asynchronous API set. A queue on a bbdev
+device accepts a burst of baseband operations using enqueue burst API. On physical
+bbdev devices the enqueue burst API will place the operations to be processed
+on the device's hardware input queue, for virtual devices the processing of the
+baseband operations is usually completed during the enqueue call to the bbdev
+device. The dequeue burst API will retrieve any processed operations available
+from the queue on the bbdev device, from physical devices this is usually
+directly from the device's processed queue, and for virtual device's from a
+``rte_ring`` where processed operations are place after being processed on the
+enqueue call.
+
+
+Enqueue / Dequeue Burst APIs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The burst enqueue API uses a bbdev device identifier and a queue
+identifier to specify the bbdev device queue to schedule the processing on.
+The ``num_ops`` parameter is the number of operations to process which are
+supplied in the ``ops`` array of ``rte_bbdev_*_op`` structures.
+The enqueue function returns the number of operations it actually enqueued for
+processing, a return value equal to ``num_ops`` means that all packets have been
+enqueued.
+
+.. code-block:: c
+
+    uint16_t rte_bbdev_enqueue_enc_ops(uint16_t dev_id, uint16_t queue_id,
+            struct rte_bbdev_enc_op **ops, uint16_t num_ops)
+
+    uint16_t rte_bbdev_enqueue_dec_ops(uint16_t dev_id, uint16_t queue_id,
+            struct rte_bbdev_dec_op **ops, uint16_t num_ops)
+
+The dequeue API uses the same format as the enqueue API of processed but
+the ``num_ops`` and ``ops`` parameters are now used to specify the max processed
+operations the user wishes to retrieve and the location in which to store them.
+The API call returns the actual number of processed operations returned, this
+can never be larger than ``num_ops``.
+
+.. code-block:: c
+
+    uint16_t rte_bbdev_dequeue_enc_ops(uint16_t dev_id, uint16_t queue_id,
+            struct rte_bbdev_enc_op **ops, uint16_t num_ops)
+
+    uint16_t rte_bbdev_dequeue_dec_ops(uint16_t dev_id, uint16_t queue_id,
+            struct rte_bbdev_dec_op **ops, uint16_t num_ops)
+
+Operation Representation
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+An encode bbdev operation is represented by ``rte_bbdev_enc_op`` structure,
+and by ``rte_bbdev_dec_op`` for decode. These structures act as metadata
+containers for all necessary information required for the bbdev operation to be
+processed on a particular bbdev device poll mode driver.
+
+.. code-block:: c
+
+    struct rte_bbdev_enc_op {
+        int status;
+        struct rte_mempool *mempool;
+        void *opaque_data;
+        struct rte_bbdev_op_turbo_enc turbo_enc;
+    };
+
+    struct rte_bbdev_dec_op {
+        int status;
+        struct rte_mempool *mempool;
+        void *opaque_data;
+        struct rte_bbdev_op_turbo_dec turbo_dec;
+    };
+
+The operation structure by itself defines the operation type. It includes an
+operation status, a reference to the operation specific data, which can vary in
+size and content depending on the operation being provisioned. It also contains
+the source mempool for the operation, if it is allocated from a mempool.
+
+If bbdev operations are allocated from a bbdev operation mempool, see next
+section, there is also the ability to allocate private memory with the
+operation for applications purposes.
+
+Application software is responsible for specifying all the operation specific
+fields in the ``rte_bbdev_*_op`` structure which are then used by the bbdev PMD
+to process the requested operation.
+
+
+Operation Management and Allocation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The bbdev library provides an API set for managing bbdev operations which
+utilize the Mempool Library to allocate operation buffers. Therefore, it ensures
+that the bbdev operation is interleaved optimally across the channels and
+ranks for optimal processing.
+
+.. code-block:: c
+
+    struct rte_mempool *
+    rte_bbdev_op_pool_create(const char *name, enum rte_bbdev_op_type type,
+            unsigned int num_elements, unsigned int cache_size,
+            int socket_id)
+
+``rte_bbdev_*_op_alloc_bulk()`` and ``rte_bbdev_*_op_free_bulk()`` are used to
+allocate bbdev operations of a specific type from a given bbdev operation mempool.
+
+.. code-block:: c
+
+    int rte_bbdev_enc_op_alloc_bulk(struct rte_mempool *mempool,
+            struct rte_bbdev_enc_op **ops, uint16_t num_ops)
+
+    int rte_bbdev_dec_op_alloc_bulk(struct rte_mempool *mempool,
+            struct rte_bbdev_dec_op **ops, uint16_t num_ops)
+
+``rte_bbdev_*_op_free_bulk()`` is called by the application to return an
+operation to its allocating pool.
+
+.. code-block:: c
+
+    void rte_bbdev_dec_op_free_bulk(struct rte_bbdev_dec_op **ops,
+            unsigned int num_ops)
+    void rte_bbdev_enc_op_free_bulk(struct rte_bbdev_enc_op **ops,
+            unsigned int num_ops)
+
+BBDEV Operations
+~~~~~~~~~~~~~~~~
+
+The bbdev operation structure contains all the mutable data relating to
+performing Turbo code processing on a referenced mbuf data buffer. It is used
+for either encode or decode operations.
+
+Turbo Encode operation accepts one input and one output.
+
+Turbo Decode operation accepts one input and two outputs, called *hard-decision*
+and *soft-decision* outputs. *Soft-decision* output is optional.
+
+It is expected that the application provides input and output ``mbuf`` pointers
+allocated and ready to use. The baseband framework supports turbo coding on
+Code Blocks (CB) and Transport Blocks (TB).
+
+For the output buffer(s), the application needs only to provide an allocated and
+free mbuf (containing only one mbuf segment), so that bbdev can write the
+operation outcome.
+
+**Turbo Encode Op structure**
+
+.. code-block:: c
+
+    struct rte_bbdev_op_turbo_enc {
+        struct rte_bbdev_op_data input;
+        struct rte_bbdev_op_data output;
+
+        uint32_t op_flags;
+        uint8_t rv_index;
+        uint8_t code_block_mode;
+        union {
+            struct rte_bbdev_op_enc_cb_params cb_params;
+            struct rte_bbdev_op_enc_tb_params tb_params;
+        };
+    };
+
+
+**Turbo Decode Op structure**
+
+.. code-block:: c
+
+    struct rte_bbdev_op_turbo_dec {
+        struct rte_bbdev_op_data input;
+        struct rte_bbdev_op_data hard_output;
+        struct rte_bbdev_op_data soft_output;
+
+        uint32_t op_flags;
+        uint8_t rv_index;
+        uint8_t iter_min:4;
+        uint8_t iter_max:4;
+        uint8_t iter_count;
+        uint8_t ext_scale;
+        uint8_t num_maps;
+        uint8_t code_block_mode;
+        union {
+            struct rte_bbdev_op_dec_cb_params cb_params;
+            struct rte_bbdev_op_dec_tb_params tb_params;
+        };
+    };
+
+Input and output data buffers are identified by ``rte_bbdev_op_data`` structure.
+This structure has three elements:
+
+- ``data`` - This is the mbuf reference
+
+- ``offset`` - The starting point for the Turbo input/output, in bytes, from the
+  start of the data in the data buffer. It must be smaller than data_len of the
+  mbuf's first segment
+
+- ``length`` - The length, in bytes, of the buffer on which the Turbo operation
+  will or has been computed. For the input, the length is set by the application.
+  For the output(s), the length is computed by the bbdev PMD driver.
+
+Sample code
+-----------
+
+The baseband device sample application gives an introduction on how to use the
+bbdev framework, by giving a sample code performing a loop-back operation with a
+baseband processor capable of transceiving data packets.
+
+The following sample C-like pseudo-code shows the basic steps to encode several
+buffers using (**sw_trubo**) bbdev PMD.

      =========================================================
 
+* **Added Wireless Base Band Device (bbdev) abstraction.**
+
+  The Wireless Baseband Device library is an acceleration abstraction
+  framework for 3gpp Layer 1 processing functions that provides a common
+  programming interface for seamless opeartion on integrated or discrete
+  hardware accelerators or using optimized software libraries for signal
+  processing.
+  The current release only supports 3GPP CRC, Turbo Coding and Rate
+  Matching operations, as specified in 3GPP TS 36.212.
+
+  See the :doc:`../prog_guide/bbdev` programmer's guide for more details.
