DPAA2 consists of sophisticated mechanisms for\n+processing Ethernet packets, queue management, buffer management,\n+autonomous L2 switching, virtual Ethernet bridging, and accelerator\n+(e.g. crypto) sharing.\n+\n+A DPAA2 hardware component called the Management Complex (or MC) manages the\n+DPAA2 hardware resources.  The MC provides an object-based abstraction for\n+software drivers to use the DPAA2 hardware.\n+\n+The MC uses DPAA2 hardware resources such as queues, buffer pools, and\n+network ports to create functional objects/devices such as network\n+interfaces, an L2 switch, or accelerator instances.\n+\n+The MC provides memory-mapped I/O command interfaces (MC portals)\n+which DPAA2 software drivers use to operate on DPAA2 objects:\n+\n+The diagram below shows an overview of the DPAA2 resource management\n+architecture:\n+\n+.. code-block:: console\n+\n+  +--------------------------------------+\n+  |                  OS                  |\n+  |                        DPAA2 drivers |\n+  |                             |        |\n+  +-----------------------------|--------+\n+                                |\n+                                | (create,discover,connect\n+                                |  config,use,destroy)\n+                                |\n+                  DPAA2         |\n+  +------------------------| mc portal |-+\n+  |                             |        |\n+  |   +- - - - - - - - - - - - -V- - -+  |\n+  |   |                               |  |\n+  |   |   Management Complex (MC)     |  |\n+  |   |                               |  |\n+  |   +- - - - - - - - - - - - - - - -+  |\n+  |                                      |\n+  | Hardware                  Hardware   |\n+  | Resources                 Objects    |\n+  | ---------                 -------    |\n+  | -queues                   -DPRC      |\n+  | -buffer pools             -DPMCP     |\n+  | -Eth MACs/ports           -DPIO      |\n+  | -network interface        -DPNI      |\n+  |  profiles                 -DPMAC     |\n+  | -queue portals            -DPBP      |\n+  | -MC portals                ...       |\n+  |  ...                                 |\n+  |                                      |\n+  +--------------------------------------+\n+\n+The MC mediates operations such as create, discover,\n+connect, configuration, and destroy.

In the example diagram below there\n+ are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)\n+ in the container.\n+\n+.. code-block:: console\n+\n+    +---------------------------------------------------------+\n+    | DPRC                                                    |\n+    |                                                         |\n+    |  +-------+  +-------+  +-------+  +-------+  +-------+  |\n+    |  | DPMCP |  | DPIO  |  | DPBP  |  | DPNI  |  | DPMAC |  |\n+    |  +-------+  +-------+  +-------+  +---+---+  +---+---+  |\n+    |  | DPMCP |  | DPIO  |                                   |\n+    |  +-------+  +-------+                                   |\n+    |  | DPMCP |                                              |\n+    |  +-------+                                              |\n+    |                                                         |\n+    +---------------------------------------------------------+\n+\n+From the point of view of an OS, a DPRC behaves similar to a plug and\n+play bus, like PCI.  DPRC commands can be used to enumerate the contents\n+of the DPRC, discover the hardware objects present (including mappable\n+regions and interrupts).\n+\n+.. code-block:: console\n+\n+    DPRC.1 (bus)\n+      |\n+      +--+--------+-------+-------+-------+\n+         |        |       |       |       |\n+       DPMCP.1  DPIO.1  DPBP.1  DPNI.1  DPMAC.1\n+       DPMCP.2  DPIO.2\n+       DPMCP.3\n+\n+Hardware objects can be created and destroyed dynamically, providing\n+the ability to hot plug/unplug objects in and out of the DPRC.\n+\n+A DPRC has a mappable MMIO region (an MC portal) that can be used\n+to send MC commands.  It has an interrupt for status events (like\n+hotplug).\n+\n+All objects in a container share the same hardware \"isolation context\".\n+This means that with respect to an IOMMU the isolation granularity\n+is at the DPRC (container) level, not at the individual object\n+level.\n+\n+DPRCs can be defined statically and populated with objects\n+via a config file passed to the MC when firmware starts\n+it.  There is also a Linux user space tool called \"restool\"\n+that can be used to create/destroy containers and objects\n+dynamically.\n+\n+DPAA2 Objects for an Ethernet Network Interface\n+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX\n+queuing mechanisms, configuration mechanisms, buffer management,\n+physical ports, and interrupts.  DPAA2 uses a more granular approach\n+utilizing multiple hardware objects.  Each object provides specialized\n+functions. Groups of these objects are used by software to provide\n+Ethernet network interface functionality.  This approach provides\n+efficient use of finite hardware resources, flexibility, and\n+performance advantages.\n+\n+The diagram below shows the objects needed for a simple\n+network interface configuration on a system with 2 CPUs.\n+\n+.. code-block:: console\n+\n+    +---+---+ +---+---+\n+       CPU0     CPU1\n+    +---+---+ +---+---+\n+        |         |\n+    +---+---+ +---+---+\n+       DPIO     DPIO\n+    +---+---+ +---+---+\n+          \\     /\n+           \\   /\n+            \\ /\n+         +---+---+\n+            DPNI  --- DPBP,DPMCP\n+         +---+---+\n+             |\n+             |\n+         +---+---+\n+           DPMAC\n+         +---+---+\n+             |\n+          port/PHY\n+\n+Below the objects are described.  For each object a brief description\n+is provided along with a summary of the kinds of operations the object\n+supports and a summary of key resources of the object (MMIO regions\n+and IRQs).\n+\n+DPMAC (Datapath Ethernet MAC): represents an Ethernet MAC, a\n+hardware device that connects to an Ethernet PHY and allows\n+physical transmission and reception of Ethernet frames.\n+\n+- MMIO regions: none\n+- IRQs: DPNI link change\n+- commands: set link up/down, link config, get stats, IRQ config, enable, reset\n+\n+DPNI (Datapath Network Interface): contains TX/RX queues,\n+network interface configuration, and RX buffer pool configuration\n+mechanisms.  The TX/RX queues are in memory and are identified by\n+queue number.\n+\n+- MMIO regions: none\n+- IRQs: link state\n+- commands: port config, offload config, queue config, parse/classify config, IRQ config, enable, reset\n+\n+DPIO (Datapath I/O): provides interfaces to enqueue and dequeue\n+packets and do hardware buffer pool management operations.  The DPAA2\n+architecture separates the mechanism to access queues (the DPIO object)\n+from the queues themselves.  The DPIO provides an MMIO interface to\n+enqueue/dequeue packets.  To enqueue something a descriptor is written\n+to the DPIO MMIO region, which includes the target queue number.\n+There will typically be one DPIO assigned to each CPU.  This allows all\n+CPUs to simultaneously perform enqueue/dequeued operations.  DPIOs are\n+expected to be shared by different DPAA2 drivers.\n+\n+- MMIO regions: queue operations, buffer management\n+- IRQs: data availability, congestion notification, buffer pool depletion\n+- commands: IRQ config, enable, reset\n+\n+DPBP (Datapath Buffer Pool): represents a hardware buffer\n+pool.\n+\n+- MMIO regions: none\n+- IRQs: none\n+- commands: enable, reset\n+\n+DPMCP (Datapath MC Portal): provides an MC command portal.\n+Used by drivers to send commands to the MC to manage\n+objects.\n+\n+- MMIO regions: MC command portal\n+- IRQs: command completion\n+- commands: IRQ config, enable, reset\n+\n+Object Connections\n+~~~~~~~~~~~~~~~~~~\n+\n+Some objects have explicit relationships that must\n+be configured:\n+\n+- DPNI <--> DPMAC\n+- DPNI <--> DPNI\n+- DPNI <--> L2-switch-port\n+\n+A DPNI must be connected to something such as a DPMAC,\n+another DPNI, or L2 switch port.  The DPNI connection\n+is made via a DPRC command.\n+\n+.. code-block:: console\n+\n+    +-------+  +-------+\n+    | DPNI  |  | DPMAC |\n+    +---+---+  +---+---+\n+        |          |\n+        +==========+\n+\n+- DPNI <--> DPBP\n+\n+A network interface requires a 'buffer pool' (DPBP object) which provides\n+a list of pointers to memory where received Ethernet data is to be copied.\n+The Ethernet driver configures the DPBPs associated with the network\n+interface.\n+\n+Interrupts\n+~~~~~~~~~~\n+\n+All interrupts generated by DPAA2 objects are message\n+interrupts.  At the hardware level message interrupts\n+generated by devices will normally have 3 components--\n+1) a non-spoofable 'device-id' expressed on the hardware\n+bus, 2) an address, 3) a data value.\n+\n+In the case of DPAA2 devices/objects, all objects in the\n+same container/DPRC share the same 'device-id'.\n+For ARM-based SoC this is the same as the stream ID.\n+\n+\n+DPAA2 DPDK - Poll Mode Driver Overview\n+--------------------------------------\n+\n+This section provides an overview of the drivers for\n+DPAA2-- 1) the bus driver and associated \"DPAA2 infrastructure\"\n+drivers and 2) functional object drivers (such as Ethernet).\n+\n+As described previously, a DPRC is a container that holds the other\n+types of DPAA2 objects.  It is functionally similar to a plug-and-play\n+bus controller.\n+\n+Each object in the DPRC is a Linux \"device\" and is bound to a driver.\n+The diagram below shows the dpaa2 drivers involved in a networking\n+scenario and the objects bound to each driver.  A brief description\n+of each driver follows.\n+\n+.. code-block: console\n+\n+\n+                                       +------------+\n+                                       | DPDK DPAA2 |\n+                                       |     PMD    |\n+                                       +------------+       +------------+\n+                                       |  Ethernet  |.......|  Mempool   |\n+                    . . . . . . . . .  |   (DPNI)   |       |  (DPBP)    |\n+                   .                   +---+---+----+       +-----+------+\n+                  .                        ^   |                  .\n+                 .                         |   |<enqueue,         .\n+                .                          |   | dequeue>         .\n+               .                           |   |                  .\n+              .                        +---+---V----+             .\n+             .      . . . . . . . . . .| DPIO driver|             .\n+            .      .                   |  (DPIO)    |             .\n+           .      .                    +-----+------+             .\n+          .      .                     |  QBMAN     |             .\n+         .      .                      |  Driver    |             .\n+    +----+------+-------+              +-----+----- |             .\n+    |   dpaa2 bus       |                    |                    .\n+    |   VFIO fslmc-bus  |....................|.....................\n+    |                   |                    |\n+    |     /bus/fslmc    |                    |\n+    +-------------------+                    |\n+                                             |\n+    ========================== HARDWARE =====|=======================\n+                                           DPIO\n+                                             |\n+                                           DPNI---DPBP\n+                                             |\n+                                           DPMAC\n+                                             |\n+                                            PHY\n+    =========================================|========================\n+\n+\n+A brief description of each driver is provided below.\n+\n+DPAA2 bus driver\n+~~~~~~~~~~~~~~~~\n+\n+The DPAA2 bus driver is a rte_bus driver which scans the fsl-mc bus.\n+Key functions include:\n+\n+- Reading the container and setting up vfio group\n+- Scanning and parsing the various MC objects and adding them to\n+  their respective device list.\n+\n+Additionally, it also provides the object driver for generic MC objects.\n+\n+DPIO driver\n+~~~~~~~~~~~\n+\n+The DPIO driver is bound to DPIO objects and provides services that allow\n+other drivers such as the Ethernet driver to enqueue and dequeue data for\n+their respective objects.\n+Key services include:\n+\n+- Data availability notifications\n+- Hardware queuing operations (enqueue and dequeue of data)\n+- Hardware buffer pool management\n+\n+To transmit a packet the Ethernet driver puts data on a queue and\n+invokes a DPIO API.
