+
+ARK Poll Mode Driver
+====================
+
+The ARK PMD is a DPDK poll-mode driver for the Atomic Rules Arkville
+(ARK) family of devices.
+
+More information can be found at the `Atomic Rules website
+<http://atomicrules.com>`_.
+
+Overview
+--------
+
+The Atomic Rules Arkville product is DPDK and AXI compliant product
+that marshals packets across a PCIe conduit between host DPDK mbufs and
+FPGA AXI streams.
+
+The ARK PMD, and the spirit of the overall Arkville product,
+has been to take the DPDK API/ABI as a fixed specification;
+then implement much of the business logic in FPGA RTL circuits.
+The approach of *working backwards* from the DPDK API/ABI and having
+the GPP host software *dictate*, while the FPGA hardware *copes*,
+results in significant performance gains over a naive implementation.
+
+While this document describes the ARK PMD software, it is helpful to
+understand what the FPGA hardware is and is not. The Arkville RTL
+component provides a single PCIe Physical Function (PF) supporting
+some number of RX/Ingress and TX/Egress Queues. The ARK PMD controls
+the Arkville core through a dedicated opaque Core BAR (CBAR).
+To allow users full freedom for their own FPGA application IP,
+an independent FPGA Application BAR (ABAR) is provided.
+
+One popular way to imagine Arkville's FPGA hardware aspect is as the
+FPGA PCIe-facing side of a so-called Smart NIC. The Arkville core does
+not contain any MACs, and is link-speed independent, as well as
+agnostic to the number of physical ports the application chooses to
+use. The ARK driver exposes the familiar PMD interface to allow packet
+movement to and from mbufs across multiple queues.
+
+However FPGA RTL applications could contain a universe of added
+functionality that an Arkville RTL core does not provide or can
+not anticipate. To allow for this expectation of user-defined
+innovation, the ARK PMD provides a dynamic mechanism of adding
+capabilities without having to modify the ARK PMD.
+
+The ARK PMD is intended to support all instances of the Arkville
+RTL Core, regardless of configuration, FPGA vendor, or target
+board. While specific capabilities such as number of physical
+hardware queue-pairs are negotiated; the driver is designed to
+remain constant over a broad and extendable feature set.
+
+Intentionally, Arkville by itself DOES NOT provide common NIC
+capabilities such as offload or receive-side scaling (RSS).
+These capabilities would be viewed as a gate-level "tax" on
+Green-box FPGA applications that do not require such function.
+Instead, they can be added as needed with essentially no
+overhead to the FPGA Application.
+
+The ARK PMD also supports optional user extensions, through dynamic linking.
+The ARK PMD user extensions are a feature of Arkville’s DPDK
+net/ark poll mode driver, allowing users to add their
+own code to extend the net/ark functionality without
+having to make source code changes to the driver. One motivation for
+this capability is that while DPDK provides a rich set of functions
+to interact with NIC-like capabilities (e.g. MAC addresses and statistics),
+the Arkville RTL IP does not include a MAC. Users can supply their
+own MAC or custom FPGA applications, which may require control from
+the PMD. The user extension is the means providing the control
+between the user's FPGA application and the existing DPDK features via
+the PMD.
+
+Device Parameters
+-------------------
+
+The ARK PMD supports a series of parameters that are used for packet routing
+and for internal packet generation and packet checking. This section describes
+the supported parameters. These features are primarily used for
+diagnostics, testing, and performance verification. The nominal use
+of Arkville does not require any configuration using these parameters.
+
+"Pkt_dir"
+
+The Packet Director controls connectivity between the Packet Generator,
+Packet Checker, UDM, DDM, and external ingress and egress interfaces for
+diagnostic purposes. It includes an internal loopback path from the DDM to the UDM.
+
+NOTE: Packets from the packet generator to the UDM are all directed to UDM RX
+queue 0. Packets looped back from the DDM to the UDM are directed to the same
+queue number they originated from.
+
+bit 24: enRxChk (default 0)
+bit 20: enDDMChk (default 1)
+bit 16: enPGIngress (default 1)
+bit 12: enPGEgress (default 0)
+bit 8: enExtIngress (default 1)
+bit 4: enDDMEgress (default 1)
+bit 0: enIntLpbk (default 0)
+
+Power On state
+0x00110110
+
+These bits control which diagnostic paths are enabled. Refer to the PktDirector block
+diagram in the Arkville documentation.
+
+Format:
+Pkt_dir=0x00110110
+
+"Pkt_gen"
+
+The packet generator parameter takes a file as its argument. The file contains configuration
+parameters used internally for regression testing and are not intended to be published at this
+level.
+
+Format:
+Pkt_gen=./config/pg.conf
+
+"Pkt_chkr"
+
+The packet checker parameter takes a file as its argument. The file contains configuration
+parameters used internally for regression testing and are not intended to be published at this
+level.
+
+Format:
+Pkt_chkr=./config/pc.conf
+
+
+Data Path Interface
+-------------------
+
+Ingress RX and Egress TX operation is by the nominal DPDK API .
+The driver supports single-port, multi-queue for both RX and TX.
+
+Refer to ``ark_ethdev.h`` for the list of supported methods to
+act upon RX and TX Queues.
+
+Configuration Information
+-------------------------
+
+**DPDK Configuration Parameters**
+
+ The following configuration options are available for the ARK PMD:
+
+ * **CONFIG_RTE_LIBRTE_ARK_PMD** (default y): Enables or disables inclusion
+ of the ARK PMD driver in the DPDK compilation.
+
+ * **CONFIG_RTE_LIBRTE_ARK_PAD_TX** (default y): When enabled TX
+ packets are padded to 60 bytes to support downstream MACS.
+
+ * **CONFIG_RTE_LIBRTE_ARK_DEBUG_RX** (default n): Enables or disables debug
+ logging and internal checking of RX ingress logic within the ARK PMD driver.
+
+ * **CONFIG_RTE_LIBRTE_ARK_DEBUG_TX** (default n): Enables or disables debug
+ logging and internal checking of TX egress logic within the ARK PMD driver.
+
+ * **CONFIG_RTE_LIBRTE_ARK_DEBUG_STATS** (default n): Enables or disables debug
+ logging of detailed packet and performance statistics gathered in
+ the PMD and FPGA.
+
+ * **CONFIG_RTE_LIBRTE_ARK_DEBUG_TRACE** (default n): Enables or disables debug
+ logging of detailed PMD events and status.
+
+
+Building DPDK
+-------------
+
+See the :ref:`DPDK Getting Started Guide for Linux <linux_gsg>` for
+instructions on how to build DPDK.
+
+By default the ARK PMD library will be built into the DPDK library.
+
+For configuring and using UIO and VFIO frameworks, please also refer :ref:`the
+documentation that comes with DPDK suite <linux_gsg>`.
+
+Supported ARK RTL PCIe Instances
+--------------------------------
+
+ARK PMD supports the following Arkville RTL PCIe instances including:
+
+* ``1d6c:100d`` - AR-ARKA-FX0 [Arkville 32B DPDK Data Mover]
+* ``1d6c:100e`` - AR-ARKA-FX1 [Arkville 64B DPDK Data Mover]
+
+Supported Operating Systems
+---------------------------
+
+Any Linux distribution fulfilling the conditions described in ``System Requirements``
+section of :ref:`the DPDK documentation <linux_gsg>` or refer to *DPDK
+Release Notes*. ARM and PowerPC architectures are not supported at this time.
+
+
+Supported Features
+------------------
+
+* Dynamic ARK PMD extensions
+* Multiple receive and transmit queues
+* Jumbo frames up to 9K
+* Hardware Statistics
+
+Unsupported Features
+--------------------
+
+Features that may be part of, or become part of, the Arkville RTL IP that are
+not currently supported or exposed by the ARK PMD include:
+
+* PCIe SR-IOV Virtual Functions (VFs)
+* Arkville's Packet Generator Control and Status
+* Arkville's Packet Director Control and Status
+* Arkville's Packet Checker Control and Status
+* Arkville's Timebase Management
+
+Pre-Requisites
+--------------
+
+#. Prepare the system as recommended by DPDK suite. This includes environment
+ variables, hugepages configuration, tool-chains and configuration
+
+#. Insert igb_uio kernel module using the command 'modprobe igb_uio'
+
+#. Bind the intended ARK device to igb_uio module
+
+At this point the system should be ready to run DPDK applications. Once the
+application runs to completion, the ARK PMD can be detached from igb_uio if necessary.
+
+Usage Example
+-------------
+
+This section demonstrates how to launch **testpmd** with Atomic Rules ARK
+devices managed by librte_pmd_ark.
+
+#. Load the kernel modules:
+
+ .. code-block:: console
+
+ modprobe uio
+ insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
+
+ .. note::
+
+ The ARK PMD driver depends upon the igb_uio user space I/O kernel module
+
+#. Mount and request huge pages:
+
+ .. code-block:: console
+
+ mount -t hugetlbfs nodev /mnt/huge
+ echo 256 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
+
+#. Bind UIO driver to ARK device at 0000:01:00.0 (using dpdk-devbind.py):
+
+ .. code-block:: console
+
+ ./usertools/dpdk-devbind.py --bind=igb_uio 0000:01:00.0
+
+ .. note::
+
+ The last argument to dpdk-devbind.py is the 4-tuple that indentifies a specific PCIe
+ device. You can use lspci -d 1d6c: to indentify all Atomic Rules devices in the system,
+ and thus determine the correct 4-tuple argument to dpdk-devbind.py
+
+#. Start testpmd with basic parameters:
+
+ .. code-block:: console
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
+
+ Example output:
+
+ .. code-block:: console
+
+ [...]
