+NXP CAAM JOB RING (caam_jr)
+===========================
+
+The caam_jr PMD provides poll mode crypto driver support for NXP SEC 4.x+ (CAAM)
+hardware accelerator. More information is available at:
+
+`NXP Cryptographic Acceleration Technology <https://www.nxp.com/applications/solutions/internet-of-things/secure-things/network-security-technology/cryptographic-acceleration-technology:NETWORK_SECURITY_CRYPTOG>`_.
+
+Architecture
+------------
+
+SEC is the SOC's security engine, which serves as NXP's latest cryptographic
+acceleration and offloading hardware. It combines functions previously
+implemented in separate modules to create a modular and scalable acceleration
+and assurance engine. It also implements block encryption algorithms, stream
+cipher algorithms, hashing algorithms, public key algorithms, run-time
+integrity checking, and a hardware random number generator. SEC performs
+higher-level cryptographic operations than previous NXP cryptographic
+accelerators. This provides significant improvement to system level performance.
+
+SEC HW accelerator above 4.x+ version are also known as CAAM.
+
+caam_jr PMD is one of DPAA drivers which uses uio interface to interact with
+Linux kernel for configure and destroy the device instance (ring).
+
+
+Implementation
+--------------
+
+SEC provides platform assurance by working with SecMon, which is a companion
+logic block that tracks the security state of the SOC. SEC is programmed by
+means of descriptors (not to be confused with frame descriptors (FDs)) that
+indicate the operations to be performed and link to the message and
+associated data. SEC incorporates two DMA engines to fetch the descriptors,
+read the message data, and write the results of the operations. The DMA
+engine provides a scatter/gather capability so that SEC can read and write
+data scattered in memory. SEC may be configured by means of software for
+dynamic changes in byte ordering. The default configuration for this version
+of SEC is little-endian mode.
+
+Note that one physical Job Ring represent one caam_jr device.
+
+Features
+--------
+
+The CAAM_JR PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_3DES_CBC``
+* ``RTE_CRYPTO_CIPHER_AES128_CBC``
+* ``RTE_CRYPTO_CIPHER_AES192_CBC``
+* ``RTE_CRYPTO_CIPHER_AES256_CBC``
+* ``RTE_CRYPTO_CIPHER_AES128_CTR``
+* ``RTE_CRYPTO_CIPHER_AES192_CTR``
+* ``RTE_CRYPTO_CIPHER_AES256_CTR``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA224_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA384_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA512_HMAC``
+* ``RTE_CRYPTO_AUTH_MD5_HMAC``
+
+AEAD algorithms:
+
+* ``RTE_CRYPTO_AEAD_AES_GCM``
+
+Supported DPAA SoCs
+--------------------
+
+* LS1046A/LS1026A
+* LS1043A/LS1023A
+* LS1028A
+* LS1012A
+
+Limitations
+-----------
+
+* Hash followed by Cipher mode is not supported
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+
+Prerequisites
+-------------
+
+caam_jr driver has following dependencies are not part of DPDK and must be installed separately:
+
+* **NXP Linux SDK**
+
+ NXP Linux software development kit (SDK) includes support for the family
+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors
+ and corresponding boards.
+
+ It includes the Linux board support packages (BSPs) for NXP SoCs,
+ a fully operational tool chain, kernel and board specific modules.
+
+ SDK and related information can be obtained from: `NXP QorIQ SDK <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
+
+Currently supported by DPDK:
+
+* NXP SDK **18.09+**.
+* Supported architectures: **arm64 LE**.
+
+* Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file
+to enable caam_jr PMD.
+
+Please note that enabling debugging options may affect system performance.
+
+* ``CONFIG_RTE_LIBRTE_PMD_CAAM_JR`` (default ``n``)
+ By default it is only enabled in common_linuxapp config.
+ Toggle compilation of the ``librte_pmd_caam_jr`` driver.
+
+* ``CONFIG_RTE_LIBRTE_PMD_CAAM_JR_BE`` (default ``n``)
+ By default it is disabled.
+ It can be used when the underlying hardware supports the CAAM in BE mode.
+ e.g. LS1043A, LS1046A supports CAAM in BE mode.
+ BE mode is enabled by default in defconfig-arm64-dpaa-linuxapp-gcc.
+
+Installations
+-------------
+To compile the caam_jr PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-armv8a-linuxapp-gcc install
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+ ./your_crypto_application <EAL args> --log-level=pmd.crypto.caam,<level>

+Compilation
+-----------
+
+The **OCTEON TX** :sup:`®` board must be running the linux kernel based on
+sdk-6.2.0 patch 3. In this, the OCTEON TX crypto PF driver is already built in.
+
+For compiling the OCTEON TX crypto poll mode driver, please check if the
+CONFIG_RTE_LIBRTE_PMD_OCTEONTX_CRYPTO setting is set to `y` in
+config/common_base file.
+
+* ``CONFIG_RTE_LIBRTE_PMD_OCTEONTX_CRYPTO=y``
+
+The following are the steps to compile the OCTEON TX crypto poll mode driver:
+
+.. code-block:: console
+
+ cd <dpdk directory>
+ make config T=arm64-thunderx-linuxapp-gcc
+ make
+
+The example applications can be compiled using the following:
+
+.. code-block:: console
+
+ cd <dpdk directory>
+ export RTE_SDK=$PWD
+ export RTE_TARGET=build
+ cd examples/<application>
+ make
+
+Execution
+---------
+
+The number of crypto VFs to be enabled can be controlled by setting sysfs entry,
+`sriov_numvfs`, for the corresponding PF driver.
+
+.. code-block:: console
+
+ echo <num_vfs> > /sys/bus/pci/devices/<dev_bus_id>/sriov_numvfs
+
+The device bus ID, `dev_bus_id`, to be used in the above step can be found out
+by using dpdk-devbind.py script. The OCTEON TX crypto PF device need to be
+identified and the corresponding device number can be used to tune various PF
+properties.
+
+
+Once the required VFs are enabled, dpdk-devbind.py script can be used to
+identify the VFs. To be accessible from DPDK, VFs need to be bound to vfio-pci
+driver:
+
+.. code-block:: console
+
+ cd <dpdk directory>
+ ./usertools/dpdk-devbind.py -u <vf device no>
+ ./usertools/dpdk-devbind.py -b vfio-pci <vf device no>
+
+Appropriate huge page need to be setup in order to run the DPDK example
+applications.
+
+.. code-block:: console
+
+ echo 8 > /sys/kernel/mm/hugepages/hugepages-524288kB/nr_hugepages
+ mkdir /mnt/huge
+ mount -t hugetlbfs nodev /mnt/huge
+
+Example applications can now be executed with crypto operations offloaded to
+OCTEON TX crypto PMD.

+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These are the build configuration options affecting QAT, and their default values:
-Acceleration services - cryptography and compression - are provided to DPDK
-applications via PMDs which register to implement the corresponding
-cryptodev and compressdev APIs.
+.. code-block:: console
-Each QuickAssist VF device can expose one cryptodev PMD and/or one compressdev PMD.
-These QAT PMDs share the same underlying device and pci-mgmt code, but are
-enumerated independently on their respective APIs and appear as independent
-devices to applications.
+ CONFIG_RTE_LIBRTE_PMD_QAT=y
+ CONFIG_RTE_LIBRTE_PMD_QAT_SYM=n
+ CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES=48
+ CONFIG_RTE_PMD_QAT_COMP_SGL_MAX_SEGMENTS=16
-.. Note::
+CONFIG_RTE_LIBRTE_PMD_QAT must be enabled for any QAT PMD to be built.
- Each VF can only be used by one DPDK process. It is not possible to share
- the same VF across multiple processes, even if these processes are using
- different acceleration services.
+The QAT cryptodev PMD has an external dependency on libcrypto, so is not
+built by default. CONFIG_RTE_LIBRTE_PMD_QAT_SYM should be enabled to build it.
- Conversely one DPDK process can use one or more QAT VFs and can expose both
- cryptodev and compressdev instances on each of those VFs.
+The QAT compressdev PMD has no external dependencies, so needs no configuration
+options and is built by default.
+The number of VFs per PF varies - see table below. If multiple QAT packages are
+installed on a platform then CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES should be
+adjusted to the number of VFs which the QAT common code will need to handle.
+Note, there is a separate config item for max cryptodevs CONFIG_RTE_CRYPTO_MAX_DEVS,
+if necessary this should be adjusted to handle the total of QAT and other devices
+which the process will use.
+
+QAT allocates internal structures to handle SGLs. For the compression service
+CONFIG_RTE_PMD_QAT_COMP_SGL_MAX_SEGMENTS can be changed if more segments are needed.
+An extra (max_inflight_ops x 16) bytes per queue_pair will be used for every increment.

+enable one cryptodev PMD and/or one compressdev PMD.
+These QAT PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+
+ Conversely one DPDK process can use one or more QAT VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.

+Distributed Software Eventdev Poll Mode Driver
+==============================================
+
+The distributed software event device is an eventdev driver which
+distributes the task of scheduling events among all the eventdev ports
+and the lcore threads using them.
+
+Features
+--------
+
+Queues
+ * Atomic
+ * Parallel
+ * Single-Link
+
+Ports
+ * Load balanced (for Atomic, Ordered, Parallel queues)
+ * Single Link (for single-link queues)
+
+Configuration and Options
+-------------------------
+
+The distributed software eventdev is a vdev device, and as such can be
+created from the application code, or from the EAL command line:
+
+* Call ``rte_vdev_init("event_dsw0")`` from the application
+
+* Use ``--vdev="event_dsw0"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dsw0"
+
+Limitations
+-----------
+
+Unattended Ports
+~~~~~~~~~~~~~~~~
+
+The distributed software eventdev uses an internal signaling schema
+between the ports to achieve load balancing. In order for this to
+work, the application must perform enqueue and/or dequeue operations
+on all ports.
+
+Producer-only ports which currently have no events to enqueue should
+periodically call rte_event_enqueue_burst() with a zero-sized burst.
+
+Ports left unattended for longer periods of time will prevent load
+balancing, and also cause traffic interruptions on the flows which
+are in the process of being migrated.
+
+Output Buffering
+~~~~~~~~~~~~~~~~
+
+For efficiency reasons, the distributed software eventdev might not
+send enqueued events immediately to the destination port, but instead
+store them in an internal buffer in the source port.
+
+In case no more events are enqueued on a port with buffered events,
+these events will be sent after the application has performed a number
+of enqueue and/or dequeue operations.
+
+For explicit flushing, an application may call
+rte_event_enqueue_burst() with a zero-sized burst.
+
+
+Priorities
+~~~~~~~~~~
+
+The distributed software eventdev does not support event priorities.
+
+Ordered Queues
+~~~~~~~~~~~~~~
+
+The distributed software eventdev does not support the ordered queue type.
+
+
+"All Types" Queues
+~~~~~~~~~~~~~~~~~~
+
+The distributed software eventdev does not support queues of type
+RTE_EVENT_QUEUE_CFG_ALL_TYPES, which allow both atomic, ordered, and
+parallel events on the same queue.
+
+Dynamic Link/Unlink
+~~~~~~~~~~~~~~~~~~~
+
+The distributed software eventdev does not support calls to
+rte_event_port_link() or rte_event_port_unlink() after
+rte_event_dev_start() has been called.

+DPDK Telemetry API User Guide
+==============================
+
+This document describes how the Data Plane Development Kit(DPDK) Telemetry API
+is used for querying port statistics from incoming traffic.
+
+Introduction
+------------
+
+The ``librte_telemetry`` provides the functionality so that users may query
+metrics from incoming port traffic. The application which initializes packet
+forwarding will act as the server, sending metrics to the requesting application
+which acts as the client.
+
+In DPDK, applications are used to initialize the ``telemetry``. To view incoming
+traffic on featured ports, the application should be run first (ie. after ports
+are configured). Once the application is running, the service assurance agent
+(for example the collectd plugin) should be run to begin querying the API.
+
+A client connects their Service Assurance application to the DPDK application
+via a UNIX socket. Once a connection is established, a client can send JSON
+messages to the DPDK application requesting metrics via another UNIX client.
+This request is then handled and parsed if valid. The response is then
+formatted in JSON and sent back to the requesting client.
+
+Pre-requisites
+~~~~~~~~~~~~~~
+
+* Python ≥ 2.5
+
+* Jansson library for JSON serialization
+
+Test Environment
+----------------
+
+``telemetry`` offers a range of selftests that a client can run within
+the DPDK application.
+
+Selftests are disabled by default. They can be enabled by setting the 'selftest'
+variable to 1 in rte_telemetry_initial_accept().
+
+Note: this 'hardcoded' value is temporary.
+
+Configuration
+-------------
+
+Enable the telemetry API by modifying the following config option before
+building DPDK::
+
+ CONFIG_RTE_LIBRTE_TELEMETRY=y
+
+Note: Meson will pick this up automatically if ``libjansson`` is available.
+
+Running the Application
+-----------------------
+
+The following steps demonstrate how to run the ``telemetry`` API to query all
+statistics on all active ports, using the ``telemetry_client`` python script
+to query.
+Note: This guide assumes packet generation is applicable and the user is
+testing with testpmd as a DPDK primary application to forward packets, although
+any DPDK application is applicable.
+
+#. Launch testpmd as the primary application with ``telemetry``.::
+
+ ./app/testpmd --telemetry
+
+#. Launch the ``telemetry`` python script with a client filepath.::
+
+ python usertools/telemetry_client.py /var/run/some_client
+
+ The client filepath is going to be used to setup our UNIX connection with the
+ DPDK primary application, in this case ``testpmd``
+ This will initialize a menu where a client can proceed to recursively query
+ statistics, request statistics once or unregister the file_path, thus exiting
+ the menu.
+
+#. Send traffic to any or all available ports from a traffic generator.
+ Select a query option(recursive or singular polling).
+ The metrics will then be displayed on the client terminal in JSON format.
+
+#. Once finished, unregister the client using the menu command.

+ENETC Overview
+~~~~~~~~~~~~~~
+
+ENETC is a PCI Integrated End Point(IEP). IEP implements
+peripheral devices in an SoC such that software sees them as PCIe device.
+ENETC is an evolution of BDR(Buffer Descriptor Ring) based networking
+IPs.
+
+This infrastructure simplifies adding support for IEP and facilitates in following:
+
+- Device discovery and location
+- Resource requirement discovery and allocation (e.g. interrupt assignment,
+ device register address)
+- Event reporting

+- Packet type information
+
+NIC Driver (PMD)
+~~~~~~~~~~~~~~~~
+
+ENETC PMD is traditional DPDK PMD which provides necessary interface between
+RTE framework and ENETC internal drivers.
+
+- Driver registers the device vendor table in PCI subsystem.
+- RTE framework scans the PCI bus for connected devices.
+- This scanning will invoke the probe function of ENETC driver.
+- The probe function will set the basic device registers and also setups BD rings.
+- On packet Rx the respective BD Ring status bit is set which is then used for
+ packet processing.
+- Then Tx is done first followed by Rx.
+
+Supported ENETC SoCs

+
+- LS1028
+
+Prerequisites
+~~~~~~~~~~~~~
+
+There are three main pre-requisities for executing ENETC PMD on a ENETC
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-i686_aarch64-linux-gnu.tar.xz>`_.
+
+2. **Linux Kernel**
+
+ It can be obtained from `NXP's Github hosting <https://source.codeaurora.org/external/qoriq/qoriq-components/linux>`_.
+
+3. **Rootfile system**
+
+ Any *aarch64* supporting filesystem can be used. For example,
+ Ubuntu 16.04 LTS (Xenial) or 18.04 (Bionic) userland which can be obtained
+ from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/18.04/release/ubuntu-base-18.04.1-base-arm64.tar.gz>`_.
+
+The following dependencies are not part of DPDK and must be installed
+separately:
+
+- **NXP Linux LSDK**
+
+ NXP Layerscape software development kit (LSDK) includes support for family
+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors
+ and corresponding boards.
+
+ It includes the Linux board support packages (BSPs) for NXP SoCs,
+ a fully operational tool chain, kernel and board specific modules.
+
+ LSDK and related information can be obtained from: `LSDK <https://www.nxp.com/support/developer-resources/run-time-software/linux-software-and-development-tools/layerscape-software-development-kit:LAYERSCAPE-SDK>`_
+
+Driver compilation and testing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Follow instructions available in the document
+:ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+to launch **testpmd**
+
+To compile in performance mode, please set ``CONFIG_RTE_CACHE_LINE_SIZE=64``

+Vectorized Rx Handler
+---------------------
+
+ENIC PMD includes a version of the receive handler that is vectorized using
+AVX2 SIMD instructions. It is meant for bulk, throughput oriented workloads
+where reducing cycles/packet in PMD is a priority. In order to use the
+vectorized handler, take the following steps.
+
+- Use a recent version of gcc, icc, or clang and build 64-bit DPDK. If
+ the compiler is known to support AVX2, DPDK build system
+ automatically compiles the vectorized handler. Otherwise, the
+ handler is not available.
+
+- Set ``devargs`` parameter ``enable-avx2-rx=1`` to explicitly request that
+ PMD consider the vectorized handler when selecting the receive handler.
+ For example::
+
+ -w 12:00.0,enable-avx2-rx=1
+
+ As the current implementation is intended for field trials, by default, the
+ vectorized handler is not considered (``enable-avx2-rx=0``).
+
+- Run on a UCS M4 or later server with CPUs that support AVX2.
+
+PMD selects the vectorized handler when the handler is compiled into
+the driver, the user requests its use via ``enable-avx2-rx=1``, CPU
+supports AVX2, and scatter Rx is not used. To verify that the
+vectorized handler is selected, enable debug logging
+(``--log-level=pmd,debug``) and check the following message.

+.. code-block:: console

+X550 does not support legacy interrupt mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Desccription
+^^^^^^^^^^^^
+X550 cannot get interrupts if using ``uio_pci_generic`` module or using legacy
+interrupt mode of ``igb_uio`` or ``vfio``. Because the errata of X550 states
+that the Interrupt Status bit is not implemented. The errata is the item #22
+from `X550 spec update <https://www.intel.com/content/dam/www/public/us/en/
+documents/specification-updates/ethernet-x550-spec-update.pdf>`_
+
+Implication
+^^^^^^^^^^^
+When using ``uio_pci_generic`` module or using legacy interrupt mode of
+``igb_uio`` or ``vfio``, the Interrupt Status bit would be checked if the
+interrupt is coming. Since the bit is not implemented in X550, the irq cannot
+be handled correctly and cannot report the event fd to DPDK apps. Then apps
+cannot get interrupts and ``dmesg`` will show messages like ``irq #No.: ``
+``nobody cared.``
+
+Workaround
+^^^^^^^^^^
+Do not bind the ``uio_pci_generic`` module in X550 NICs.
+Do not bind ``igb_uio`` with legacy mode in X550 NICs.
+Before binding ``vfio`` with legacy mode in X550 NICs, use ``modprobe vfio ``
+``nointxmask=1`` to load ``vfio`` module if the intx is not shared with other
+devices.

+MVNETA Poll Mode Driver
+=======================
+
+The MVNETA PMD (librte_pmd_mvneta) provides poll mode driver support
+for the Marvell NETA 1/2.5 Gbps adapter.
+
+Detailed information about SoCs that use PPv2 can be obtained here:
+
+* https://www.marvell.com/embedded-processors/armada-3700/
+
+.. Note::
+
+ Due to external dependencies, this driver is disabled by default. It must
+ be enabled manually by setting relevant configuration option manually.
+ Please refer to `Config File Options`_ section for further details.
+
+
+Features
+--------
+
+Features of the MVNETA PMD are:
+
+- Start/stop
+- tx/rx_queue_setup
+- tx/rx_burst
+- Speed capabilities
+- Jumbo frame
+- MTU update
+- Promiscuous mode
+- Unicast MAC filter
+- Link status
+- CRC offload
+- L3 checksum offload
+- L4 checksum offload
+- Packet type parsing
+- Basic stats
+
+
+Limitations
+-----------
+
+- Flushing vlans added for filtering is not possible due to MUSDK missing
+ functionality. Current workaround is to reset board so that NETA has a
+ chance to start in a sane state.
+
+Prerequisites
+-------------
+
+- Custom Linux Kernel sources
+
+ .. code-block:: console
+
+ git clone https://github.com/MarvellEmbeddedProcessors/linux-marvell.git -b linux-4.4.120-armada-18.09

+
+ MUSDK is a light-weight library that provides direct access to Marvell's
+ NETA. Alternatively prebuilt MUSDK library can be
+ requested from `Marvell Extranet <https://extranet.marvell.com>`_. Once
+ approval has been granted, library can be found by typing ``musdk`` in
+ the search box.
+
+ MUSDK must be configured with the following features:
+
+ .. code-block:: console
+
+ --enable-pp2=no --enable-neta

+Traffic Management API
+----------------------
+
+MVPP2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+1. Hierarchical scheduling
+2. Traffic shaping
+3. Congestion management
+4. Packet marking
+
+Internally TM is represented by a hierarchy (tree) of nodes.
+Node which has a parent is called a leaf whereas node without
+parent is called a non-leaf (root).
+MVPP2 PMD supports two level hierarchy where level 0 represents ports and level 1 represents tx queues of a given port.
+
+.. figure:: img/mvpp2_tm.svg
+
+Nodes hold following types of settings:
+
+- for egress scheduler configuration: weight
+- for egress rate limiter: private shaper
+- bitmask indicating which statistics counters will be read
+
+Hierarchy is always constructed from the top, i.e first a root node is added
+then some number of leaf nodes. Number of leaf nodes cannot exceed number
+of configured tx queues.
+
+After hierarchy is complete it can be committed.
+
+
+For an additional description please refer to DPDK :doc:`Traffic Management API <../prog_guide/traffic_management>`.
+
+Limitations
+~~~~~~~~~~~
+
+The following capabilities are not supported:
+
+- Traffic manager WRED profile and WRED context
+- Traffic manager shared shaper update
+- Traffic manager packet marking
+- Maximum number of levels in hierarchy is 2

+QoS API Support:
+----------------
+
+SoftNIC PMD implements ethdev traffic management APIs ``rte_tm.h`` that
+allow building and committing traffic manager hierarchy, configuring hierarchy
+nodes of the Quality of Service (QoS) scheduler supported by DPDK librte_sched
+library. Furthermore, APIs for run-time update to the traffic manager hierarchy
+are supported by PMD.
+
+SoftNIC PMD also implements ethdev traffic metering and policing APIs
+``rte_mtr.h`` that enables metering and marking of the packets with the
+appropriate color (green, yellow or red), according to the traffic metering
+algorithm. For the meter output color, policer actions like
+`keep the packet color same`, `change the packet color` or `drop the packet`
+can be configured.
+
+.. Note::
+
+ The SoftNIC does not support the meter object shared by several flows,
+ thus only supports creating meter object private to the flow. Once meter
+ object is successfully created, it can be linked to the specific flow by
+ specifying the ``meter`` flow action in the flow rule.
+
+Flow API support:
+-----------------
+
+The SoftNIC PMD implements ethdev flow APIs ``rte_flow.h`` that allow validating
+flow rules, adding flow rules to the SoftNIC pipeline as table rules, deleting
+and querying the flow rules. The PMD provides new cli command for creating the
+flow group and their mapping to the SoftNIC pipeline and table. This cli should
+be configured as part of firmware file.
+
+ .. code-block:: console
+
+ flowapi map group <group_id> ingress | egress pipeline <pipeline_name> \
+ table <table_id>
+
+From the flow attributes of the flow, PMD uses the group id to get the mapped
+pipeline and table. PMD supports number of flow actions such as
+``JMP, QUEUE, RSS, DROP, COUNT, METER, VXLAN`` etc.
+
+.. Note::
+
+ The flow must have one terminating actions i.e.
+ ``JMP or RSS or QUEUE or DROP``. For the count and drop actions the
+ underlying PMD doesn't support the functionality yet. So it is not
+ recommended for use.
+
+The flow API can be tested with the help of testpmd application. The SoftNIC
+firmware specifies CLI commands for port configuration, pipeline creation,
+action profile creation and table creation. Once application gets initialized,
+the flow rules can be added through the testpmd CLI.
+The PMD will translate the flow rules to the SoftNIC pipeline tables rules.

+Multi-process sharing
+---------------------
+
+It is possible to attach an existing TAP device in a secondary process,
+by declaring it as a vdev with the same name as in the primary process,
+and without any parameter.
+
+The port attached in a secondary process will give access to the
+statistics and the queues.
+Therefore it can be used for monitoring or Rx/Tx processing.
+
+The IPC synchronization of Rx/Tx queues is currently limited:
+
+ - Maximum 8 queues shared
+ - Synchronized on probing, but not on later port update

+Support for Externally Allocated Memory
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to use externally allocated memory in DPDK, using a set of malloc
+heap API's. Support for externally allocated memory is implemented through
+overloading the socket ID - externally allocated heaps will have socket ID's
+that would be considered invalid under normal circumstances. Requesting an
+allocation to take place from a specified externally allocated memory is a
+matter of supplying the correct socket ID to DPDK allocator, either directly
+(e.g. through a call to ``rte_malloc``) or indirectly (through data
+structure-specific allocation API's such as ``rte_ring_create``).
+
+Since there is no way DPDK can verify whether memory are is available or valid,
+this responsibility falls on the shoulders of the user. All multiprocess
+synchronization is also user's responsibility, as well as ensuring that all
+calls to add/attach/detach/remove memory are done in the correct order. It is
+not required to attach to a memory area in all processes - only attach to memory
+areas as needed.
+
+The expected workflow is as follows:
+
+* Get a pointer to memory area
+* Create a named heap
+* Add memory area(s) to the heap
+ - If IOVA table is not specified, IOVA addresses will be assumed to be
+ unavailable, and DMA mappings will not be performed
+ - Other processes must attach to the memory area before they can use it
+* Get socket ID used for the heap
+* Use normal DPDK allocation procedures, using supplied socket ID
+* If memory area is no longer needed, it can be removed from the heap
+ - Other processes must detach from this memory area before it can be removed
+* If heap is no longer needed, remove it
+ - Socket ID will become invalid and will not be reused
+
+For more information, please refer to ``rte_malloc`` API documentation,
+specifically the ``rte_malloc_heap_*`` family of function calls.

+Event Ethernet Tx Adapter Library
+=================================
+
+The DPDK Eventdev API allows the application to use an event driven programming
+model for packet processing in which the event device distributes events
+referencing packets to the application cores in a dynamic load balanced fashion
+while handling atomicity and packet ordering. Event adapters provide the interface
+between the ethernet, crypto and timer devices and the event device. Event adapter
+APIs enable common application code by abstracting PMD specific capabilities.
+The Event ethernet Tx adapter provides configuration and data path APIs for the
+transmit stage of the application allowing the same application code to use eventdev
+PMD support or in its absence, a common implementation.
+
+In the common implementation, the application enqueues mbufs to the adapter
+which runs as a rte_service function. The service function dequeues events
+from its event port and transmits the mbufs referenced by these events.
+
+
+API Walk-through
+----------------
+
+This section will introduce the reader to the adapter API. The
+application has to first instantiate an adapter which is associated with
+a single eventdev, next the adapter instance is configured with Tx queues,
+finally the adapter is started and the application can start enqueuing mbufs
+to it.
+
+Creating an Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+An adapter instance is created using ``rte_event_eth_tx_adapter_create()``. This
+function is passed the event device to be associated with the adapter and port
+configuration for the adapter to setup an event port if the adapter needs to use
+a service function.
+
+If the application desires to have finer control of eventdev port configuration,
+it can use the ``rte_event_eth_tx_adapter_create_ext()`` function. The
+``rte_event_eth_tx_adapter_create_ext()`` function is passed a callback function.
+The callback function is invoked if the adapter needs to use a service function
+and needs to create an event port for it. The callback is expected to fill the
+``struct rte_event_eth_tx_adapter_conf`` structure passed to it.
+
+.. code-block:: c
+
+ struct rte_event_dev_info dev_info;
+ struct rte_event_port_conf tx_p_conf = {0};
+
+ err = rte_event_dev_info_get(id, &dev_info);
+
+ tx_p_conf.new_event_threshold = dev_info.max_num_events;
+ tx_p_conf.dequeue_depth = dev_info.max_event_port_dequeue_depth;
+ tx_p_conf.enqueue_depth = dev_info.max_event_port_enqueue_depth;
+
+ err = rte_event_eth_tx_adapter_create(id, dev_id, &tx_p_conf);
+
+Adding Tx Queues to the Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Ethdev Tx queues are added to the instance using the
+``rte_event_eth_tx_adapter_queue_add()`` function. A queue value
+of -1 is used to indicate all queues within a device.
+
+.. code-block:: c
+
+ int err = rte_event_eth_tx_adapter_queue_add(id,
+ eth_dev_id,
+ q);
+
+Querying Adapter Capabilities
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``rte_event_eth_tx_adapter_caps_get()`` function allows
+the application to query the adapter capabilities for an eventdev and ethdev
+combination. Currently, the only capability flag defined is
+``RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT``, the application can
+query this flag to determine if a service function is associated with the
+adapter and retrieve its service identifier using the
+``rte_event_eth_tx_adapter_service_id_get()`` API.
+
+
+.. code-block:: c
+
+ int err = rte_event_eth_tx_adapter_caps_get(dev_id, eth_dev_id, &cap);
+
+ if (!(cap & RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT))
+ err = rte_event_eth_tx_adapter_service_id_get(id, &service_id);
+
+Linking a Queue to the Adapter's Event Port
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the adapter uses a service function as described in the previous section, the
+application is required to link a queue to the adapter's event port. The adapter's
+event port can be obtained using the ``rte_event_eth_tx_adapter_event_port_get()``
+function. The queue can be configured with the ``RTE_EVENT_QUEUE_CFG_SINGLE_LINK``
+since it is linked to a single event port.
+
+Configuring the Service Function
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the adapter uses a service function, the application can assign
+a service core to the service function as shown below.
+
+.. code-block:: c
+
+ if (rte_event_eth_tx_adapter_service_id_get(id, &service_id) == 0)
+ rte_service_map_lcore_set(service_id, TX_CORE_ID);
+
+Starting the Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The application calls ``rte_event_eth_tx_adapter_start()`` to start the adapter.
+This function calls the start callback of the eventdev PMD if supported,
+and the ``rte_service_run_state_set()`` to enable the service function if one exists.
+
+Enqueuing Packets to the Adapter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The application needs to notify the adapter about the transmit port and queue used
+to send the packet. The transmit port is set in the ``struct rte mbuf::port`` field
+and the transmit queue is set using the ``rte_event_eth_tx_adapter_txq_set()``
+function.
+
+If the eventdev PMD supports the ``RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT``
+capability for a given ethernet device, the application should use the
+``rte_event_eth_tx_adapter_enqueue()`` function to enqueue packets to the adapter.
+
+If the adapter uses a service function for the ethernet device then the application
+should use the ``rte_event_enqueue_burst()`` function.
+
+.. code-block:: c
+
+ struct rte_event event;
+
+ if (cap & RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT) {
+
+ event.mbuf = m;
+
+ m->port = tx_port;
+ rte_event_eth_tx_adapter_txq_set(m, tx_queue_id);
+
+ rte_event_eth_tx_adapter_enqueue(dev_id, ev_port, &event, 1);
+ } else {
+
+ event.queue_id = qid; /* event queue linked to adapter port */
+ event.op = RTE_EVENT_OP_NEW;
+ event.event_type = RTE_EVENT_TYPE_CPU;
+ event.sched_type = RTE_SCHED_TYPE_ATOMIC;
+ event.mbuf = m;
+
+ m->port = tx_port;
+ rte_event_eth_tx_adapter_txq_set(m, tx_queue_id);
+
+ rte_event_enqueue_burst(dev_id, ev_port, &event, 1);
+ }
+
+Getting Adapter Statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``rte_event_eth_tx_adapter_stats_get()`` function reports counters defined
+in struct ``rte_event_eth_tx_adapter_stats``. The counter values are the sum of
+the counts from the eventdev PMD callback if the callback is supported, and
+the counts maintained by the service function, if one exists.

+Loopback Mode
+~~~~~~~~~~~~~
+
+For testing, the ``rte_kni`` kernel module can be loaded in loopback mode
+by specifying the ``lo_mode`` parameter:
+
+.. code-block:: console
+
+ # insmod kmod/rte_kni.ko lo_mode=lo_mode_fifo
+
+The ``lo_mode_fifo`` loopback option will loop back ring enqueue/dequeue
+operations in kernel space.
+
+.. code-block:: console
+
+ # insmod kmod/rte_kni.ko lo_mode=lo_mode_fifo_skb
+
+The ``lo_mode_fifo_skb`` loopback option will loop back ring enqueue/dequeue
+operations and sk buffer copies in kernel space.
+
+If the ``lo_mode`` parameter is not specified, loopback mode is disabled.
+
+.. _kni_kernel_thread_mode:
+
+Kernel Thread Mode
+~~~~~~~~~~~~~~~~~~
+
+To provide flexibility of performance, the ``rte_kni`` KNI kernel module
+can be loaded with the ``kthread_mode`` parameter. The ``rte_kni`` kernel
+module supports two options: "single kernel thread" mode and "multiple
+kernel thread" mode.
+
+Single kernel thread mode is enabled as follows:
+
+.. code-block:: console
+
+ # insmod kmod/rte_kni.ko kthread_mode=single
+
+This mode will create only one kernel thread for all KNI interfaces to
+receive data on the kernel side. By default, this kernel thread is not
+bound to any particular core, but the user can set the core affinity for
+this kernel thread by setting the ``core_id`` and ``force_bind`` parameters
+in ``struct rte_kni_conf`` when the first KNI interface is created:
+
+For optimum performance, the kernel thread should be bound to a core in
+on the same socket as the DPDK lcores used in the application.
+
+The KNI kernel module can also be configured to start a separate kernel
+thread for each KNI interface created by the DPDK application. Multiple
+kernel thread mode is enabled as follows:
+
+.. code-block:: console
+
+ # insmod kmod/rte_kni.ko kthread_mode=multiple
+
+This mode will create a separate kernel thread for each KNI interface to
+receive data on the kernel side. The core affinity of each ``kni_thread``
+kernel thread can be specified by setting the ``core_id`` and ``force_bind``
+parameters in ``struct rte_kni_conf`` when each KNI interface is created.
+
+Multiple kernel thread mode can provide scalable higher performance if
+sufficient unused cores are available on the host system.
+
+If the ``kthread_mode`` parameter is not specified, the "single kernel
+thread" mode is used.
+
+.. _kni_default_carrier_state:
+
+Default Carrier State
+~~~~~~~~~~~~~~~~~~~~~
+
+The default carrier state of KNI interfaces created by the ``rte_kni``
+kernel module is controlled via the ``carrier`` option when the module
+is loaded.
+
+If ``carrier=off`` is specified, the kernel module will leave the carrier
+state of the interface *down* when the interface is management enabled.
+The DPDK application can set the carrier state of the KNI interface using the
+``rte_kni_update_link()`` function. This is useful for DPDK applications
+which require that the carrier state of the KNI interface reflect the
+actual link state of the corresponding physical NIC port.
+
+If ``carrier=on`` is specified, the kernel module will automatically set
+the carrier state of the interface to *up* when the interface is management
+enabled. This is useful for DPDK applications which use the KNI interface as
+a purely virtual interface that does not correspond to any physical hardware
+and do not wish to explicitly set the carrier state of the interface with
+``rte_kni_update_link()``. It is also useful for testing in loopback mode
+where the NIC port may not be physically connected to anything.
+
+To set the default carrier state to *on*:
+
+.. code-block:: console

KNI Creation and Deletion
-------------------------
-The KNI interfaces are created by a DPDK application dynamically.
-The interface name and FIFO details are provided by the application through an ioctl call
-using the rte_kni_device_info struct which contains:
+Before any KNI interfaces can be created, the ``rte_kni`` kernel module must
+be loaded into the kernel and configured withe ``rte_kni_init()`` function.
+
+The KNI interfaces are created by a DPDK application dynamically via the
+``rte_kni_alloc()`` function.
+
+The ``struct rte_kni_conf`` structure contains fields which allow the
+user to specify the interface name, set the MTU size, set an explicit or
+random MAC address and control the affinity of the kernel Rx thread(s)
+(both single and multi-threaded modes).
+
+The ``struct rte_kni_ops`` structure contains pointers to functions to
+handle requests from the ``rte_kni`` kernel module. These functions
+allow DPDK applications to perform actions when the KNI interfaces are
+manipulated by control commands or functions external to the application.
+
+For example, the DPDK application may wish to enabled/disable a physical
+NIC port when a user enabled/disables a KNI interface with ``ip link set
+[up|down] dev <ifaceX>``. The DPDK application can register a callback for
+``config_network_if`` which will be called when the interface management
+state changes.
+
+There are currently four callbacks for which the user can register
+application functions:
-* The interface name.
+``config_network_if``:
-* Physical addresses of the corresponding memzones for the relevant FIFOs.
+ Called when the management state of the KNI interface changes.
+ For example, when the user runs ``ip link set [up|down] dev <ifaceX>``.
-* Mbuf mempool details, both physical and virtual (to calculate the offset for mbuf pointers).
+``change_mtu``:
-* PCI information.
+ Called when the user changes the MTU size of the KNI
+ interface. For example, when the user runs ``ip link set mtu <size>
+ dev <ifaceX>``.
-* Core affinity.
+``config_mac_address``:
-Refer to rte_kni_common.h in the DPDK source code for more details.
+ Called when the user changes the MAC address of the KNI interface.
+ For example, when the user runs ``ip link set address <MAC>
+ dev <ifaceX>``. If the user sets this callback function to NULL,
+ but sets the ``port_id`` field to a value other than -1, a default
+ callback handler in the rte_kni library ``kni_config_mac_address()``
+ will be called which calls ``rte_eth_dev_default_mac_addr_set()``
+ on the specified ``port_id``.
-The physical addresses will be re-mapped into the kernel address space and stored in separate KNI contexts.
+``config_promiscusity``:
-The affinity of kernel RX thread (both single and multi-threaded modes) is controlled by force_bind and
-core_id config parameters.
+ Called when the user changes the promiscusity state of the KNI
+ interface. For example, when the user runs ``ip link set promisc
+ [on|off] dev <ifaceX>``. If the user sets this callback function to
+ NULL, but sets the ``port_id`` field to a value other than -1, a default
+ callback handler in the rte_kni library ``kni_config_promiscusity()``
+ will be called which calls ``rte_eth_promiscuous_<enable|disable>()``
+ on the specified ``port_id``.
-The KNI interfaces can be deleted by a DPDK application dynamically after being created.
-Furthermore, all those KNI interfaces not deleted will be deleted on the release operation
-of the miscellaneous device (when the DPDK application is closed).
+In order to run these callbacks, the application must periodically call
+the ``rte_kni_handle_request()`` function. Any user callback function
+registered will be called directly from ``rte_kni_handle_request()`` so
+care must be taken to prevent deadlock and to not block any DPDK fastpath
+tasks. Typically DPDK applications which use these callbacks will need
+to create a separate thread or secondary process to periodically call
+``rte_kni_handle_request()``.
+
+The KNI interfaces can be deleted by a DPDK application with
+``rte_kni_release()``. All KNI interfaces not explicitly deleted will be
+deleted when the the ``/dev/kni`` device is closed, either explicitly with
+``rte_kni_close()`` or when the DPDK application is closed.

-Port Hotplug Framework
-======================
-
-The Port Hotplug Framework provides DPDK applications with the ability to
-attach and detach ports at runtime. Because the framework depends on PMD
-implementation, the ports that PMDs cannot handle are out of scope of this
-framework. Furthermore, after detaching a port from a DPDK application, the
-framework doesn't provide a way for removing the devices from the system.
-For the ports backed by a physical NIC, the kernel will need to support PCI
-Hotplug feature.
-
-Overview
---------
-
-The basic requirements of the Port Hotplug Framework are:
-
-* DPDK applications that use the Port Hotplug Framework must manage their
- own ports.
-
- The Port Hotplug Framework is implemented to allow DPDK applications to
- manage ports. For example, when DPDK applications call the port attach
- function, the attached port number is returned. DPDK applications can
- also detach the port by port number.
-
-* Kernel support is needed for attaching or detaching physical device
- ports.
-
- To attach new physical device ports, the device will be recognized by
- userspace driver I/O framework in kernel at first. Then DPDK
- applications can call the Port Hotplug functions to attach the ports.
- For detaching, steps are vice versa.
-
-* Before detaching, they must be stopped and closed.
-
- DPDK applications must call "rte_eth_dev_stop()" and
- "rte_eth_dev_close()" APIs before detaching ports. These functions will
- start finalization sequence of the PMDs.
-
-* The framework doesn't affect legacy DPDK applications behavior.
-
- If the Port Hotplug functions aren't called, all legacy DPDK apps can
- still work without modifications.
-
-Port Hotplug API overview
--------------------------
-
-* Attaching a port
-
- "rte_eth_dev_attach()" API attaches a port to DPDK application, and
- returns the attached port number. Before calling the API, the device
- should be recognized by an userspace driver I/O framework. The API
- receives a pci address like "0000:01:00.0" or a virtual device name
- like "net_pcap0,iface=eth0". In the case of virtual device name, the
- format is the same as the general "--vdev" option of DPDK.
-
-* Detaching a port
-
- "rte_eth_dev_detach()" API detaches a port from DPDK application, and
- returns a pci address of the detached device or a virtual device name
- of the device.
-
-Reference
----------
-
- "testpmd" supports the Port Hotplug Framework.
-
-Limitations
------------
-
-* The Port Hotplug APIs are not thread safe.
-
-* The framework can only be enabled with Linux. BSD is not supported.
-
-* Not all PMDs support detaching feature.
- The underlying bus must support hot-unplug. If not supported,
- the function ``rte_eth_dev_detach()`` will return negative ENOTSUP.

The power management mechanism is used to save power when performing L3 forwarding.
+
+Empty Poll API
+--------------
+
+Abstract
+~~~~~~~~
+
+For packet processing workloads such as DPDK polling is continuous.
+This means CPU cores always show 100% busy independent of how much work
+those cores are doing. It is critical to accurately determine how busy
+a core is hugely important for the following reasons:
+
+ * No indication of overload conditions
+ * User does not know how much real load is on a system, resulting
+ in wasted energy as no power management is utilized
+
+Compared to the original l3fwd-power design, instead of going to sleep
+after detecting an empty poll, the new mechanism just lowers the core frequency.
+As a result, the application does not stop polling the device, which leads
+to improved handling of bursts of traffic.
+
+When the system become busy, the empty poll mechanism can also increase the core
+frequency (including turbo) to do best effort for intensive traffic. This gives
+us more flexible and balanced traffic awareness over the standard l3fwd-power
+application.
+
+
+Proposed Solution
+~~~~~~~~~~~~~~~~~
+The proposed solution focuses on how many times empty polls are executed.
+The less the number of empty polls, means current core is busy with processing
+workload, therefore, the higher frequency is needed. The high empty poll number
+indicates the current core not doing any real work therefore, we can lower the
+frequency to safe power.
+
+In the current implementation, each core has 1 empty-poll counter which assume
+1 core is dedicated to 1 queue. This will need to be expanded in the future to
+support multiple queues per core.
+
+Power state definition:
+^^^^^^^^^^^^^^^^^^^^^^^
+
+* LOW: Not currently used, reserved for future use.
+
+* MED: the frequency is used to process modest traffic workload.
+
+* HIGH: the frequency is used to process busy traffic workload.
+
+There are two phases to establish the power management system:
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+* Training phase. This phase is used to measure the optimal frequency
+ change thresholds for a given system. The thresholds will differ from
+ system to system due to differences in processor micro-architecture,
+ cache and device configurations.
+ In this phase, the user must ensure that no traffic can enter the
+ system so that counts can be measured for empty polls at low, medium
+ and high frequencies. Each frequency is measured for two seconds.
+ Once the training phase is complete, the threshold numbers are
+ displayed, and normal mode resumes, and traffic can be allowed into
+ the system. These threshold number can be used on the command line
+ when starting the application in normal mode to avoid re-training
+ every time.
+
+* Normal phase. Every 10ms the run-time counters are compared
+ to the supplied threshold values, and the decision will be made
+ whether to move to a different power state (by adjusting the
+ frequency).
+
+API Overview for Empty Poll Power Management
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* **State Init**: initialize the power management system.
+
+* **State Free**: free the resource hold by power management system.
+
+* **Update Empty Poll Counter**: update the empty poll counter.
+
+* **Update Valid Poll Counter**: update the valid poll counter.
+
+* **Set the Fequence Index**: update the power state/frequency mapping.
+
+* **Detect empty poll state change**: empty poll state change detection algorithm then take action.
+
+User Cases
+----------
+The mechanism can applied to any device which is based on polling. e.g. NIC, FPGA.

+ =========================================================
+
+* **Added support for using externally allocated memory in DPDK.**
+
+ DPDK has gained support for creating new ``rte_malloc`` heaps referencing
+ memory that was created outside of DPDK's own page allocator, and using that
+ memory natively with any other DPDK library or data structure.
+
+* **Added check for ensuring allocated memory addressable by devices.**
+
+ Some devices can have addressing limitations so a new function,
+ ``rte_eal_check_dma_mask``, has been added for checking allocated memory is
+ not out of the device range. Because now memory can be dynamically allocated
+ after initialization, a dma mask is kept and any new allocated memory will be
+ checked out against that dma mask and rejected if out of range. If more than
+ one device has addressing limitations, the dma mask is the more restricted one.
+
+* **Added hot-unplug handle mechanism.**
+
+ ``rte_dev_hotplug_handle_enable`` and ``rte_dev_hotplug_handle_disable`` are
+ for enabling or disabling hotplug handle mechanism.
+
+* **Support device multi-process hotplug.**
+
+ Hotplug and hot-unplug for devices will now be supported in multiprocessing
+ scenario. Any ethdev devices created in the primary process will be regarded
+ as shared and will be available for all DPDK processes. Synchronization
+ between processes will be done using DPDK IPC.
+
+* **Added new Flow API actions to rewrite fields in packet headers.**
+
+ Added new Flow API actions to:
+
+ * Modify source and destination IP addresses in the outermost IPv4/IPv6
+ headers.
+ * Modify source and destination port numbers in the outermost TCP/UDP
+ headers.
+
+* **Added new Flow API action to swap MAC addresses in Ethernet header.**
+
+ Added new Flow API action to swap the source and destination MAC
+ addresses in the outermost Ethernet header.
+
+* **Add support to offload more flow match and actions for CXGBE PMD**
+
+ Flow API support has been enhanced for CXGBE Poll Mode Driver to offload:
+
+ * Match items: destination MAC address.
+ * Action items: push/pop/rewrite vlan header,
+ rewrite IP addresses in outermost IPv4/IPv6 header,
+ rewrite port numbers in outermost TCP/UDP header,
+ swap MAC addresses in outermost Ethernet header.
+
+* **Added a devarg to use the latest supported vector path in i40e.**
+ A new devarg ``use-latest-supported-vec`` was introduced to allow users to
+ choose the latest vector path that the platform supported. For example, users
+ can use AVX2 vector path on BDW/HSW to get better performance.
+
+* **Added support for SR-IOV in netvsc PMD.**
+
+ The ``netvsc`` poll mode driver now supports the Accelerated Networking
+ SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
+ vdev_netvsc, tap, and failsafe drivers combination.
+
+* **Added a new net driver for Marvell Armada 3k device.**
+
+ Added the new ``mvneta`` net driver for Marvell Armada 3k device. See the
+ :doc:`../nics/mvneta` NIC guide for more details on this new driver.
+
+* **Added NXP ENETC PMD.**
+
+ Added the new enetc driver for NXP enetc platform. See the
+ "ENETC Poll Mode Driver" document for more details on this new driver.
+
+* **Added Ethernet poll mode driver for Aquantia aQtion family of 10G devices.**
+
+ Added the new ``atlantic`` ethernet poll mode driver for Aquantia XGBE devices.
+ See the :doc:`../nics/atlantic` nic driver guide for more details on this
+ driver.
+
+* **Updated Solarflare network PMD.**
+
+ Updated the sfc_efx driver including the following changes:
+
+ * Added support for Rx scatter in EF10 datapath implementation.
+ * Added support for Rx descriptor status API in EF10 datapath implementation.
+ * Added support for TSO in EF10 datapath implementation.
+ * Added support for Tx descriptor status API in EF10 (ef10 and ef10_simple)
+ datapaths implementation.
+
+* **Updated the enic driver.**
+
+ * Added AVX2-based vectorized Rx handler.
+ * Added VLAN and checksum offloads to the simple Tx handler.
+ * Added the count flow action.
+ * Enabled the virtual address IOVA mode.
+
+* **Updated failsafe driver.**
+
+ Updated the failsafe driver including the following changes:
+
+ * Support for Rx and Tx queues start and stop.
+ * Support for Rx and Tx queues deferred start.
+ * Support for runtime Rx and Tx queues setup.
+ * Support multicast MAC address set.
+
+* **Added a devarg to use PCAP interface physical MAC address.**
+ A new devarg ``phy_mac`` was introduced to allow users to use physical
+ MAC address of the selected PCAP interface.
+
+* **Added TAP Rx/Tx queues sharing with a secondary process.**
+
+ A secondary process can attach a TAP device created in the primary process,
+ probe the queues, and process Rx/Tx in a secondary process.
+
+* **Added classification and metering support to SoftNIC PMD.**
+
+ Added support for flow classification (rte_flow API), and metering and
+ policing (rte_mtr API) to the SoftNIC PMD.
+
+* **Added Crypto support to Softnic PMD.**
+
+ The Softnic is now capable of processing symmetric crypto workloads such
+ as cipher, cipher-authentication chaining, and aead encryption and
+ decryption. This is achieved by calling DPDK Cryptodev APIs.
+
+* **Added cryptodev port to port library.**
+
+ Cryptodev port is a shim layer in the port library that interacts with DPDK
+ Cryptodev PMDs including burst enqueuing and dequeuing crypto operations.
+
+* **Added symmetric cryptographic actions to the pipeline library.**
+
+ In the pipeline library an added symmetric crypto action parsing and action
+ handler are implemented. The action allows automatically preparing the crypto
+ operation with the rules specified such as algorithm, key, and IV, etc for
+ the cryptodev port to process.
+
+* **Added support for GEN3 devices to Intel QAT driver .**
+
+ Added support for the third generation of Intel QuickAssist devices.
+
+* **Updated the QAT PMD.**
+
+ The QAT PMD was updated with additional support for:
+
+ * AES-CMAC algorithm.
+
+* **Updated the AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for AES-GCM
+ algorithm support.
+
+* **Added NXP CAAM JR PMD.**
+
+ Added the new caam job ring driver for NXP platforms. See the
+ "NXP CAAM JOB RING (caam_jr)" document for more details on this new driver.
+
+* **Added support for Dynamic Huffman Encoding to Intel QAT comp PMD.**
+
+ The Intel QuickAssist (QAT) compression PMD has been updated with support
+ for Dynamic Huffman Encoding for the Deflate algorithm.
+
+* **Added Event Ethernet Tx Adapter.**
+
+ Added event ethernet Tx adapter library that provides configuration and
+ data path APIs for the ethernet transmit stage of an event driven packet
+ processing application. These APIs abstract the implementation of the
+ transmit stage and allow the application to use eventdev PMD support or
+ a common implementation.
+
+* **Added Distributed Software Eventdev PMD.**
+
+ Added the new Distributed Software Event Device (DSW), which is a
+ pure-software eventdev driver distributing the work of scheduling
+ among all eventdev ports and the lcores using them. DSW, compared to
+ the SW eventdev PMD, sacrifices load balancing performance to
+ gain better event scheduling throughput and scalability.
+
+* **Added extendable bucket feature to hash library (rte_hash).**
+
+ This new “extendable bucket” feature provides 100% insertion guarantee to
+ the capacity specified by the user by extending hash table with extra
+ buckets when needed to accommodate the unlikely event of intensive hash
+ collisions. In addition, the internal hashing algorithm was changed to use
+ partial-key hashing to improve memory efficiency and lookup performance.
+
+* **Added lock free reader/writer concurrency to hash library (rte_hash).**
+
+ Lock free reader/writer concurrency prevents the readers from getting
+ blocked due to a pre-empted writer thread. This allows the hash library
+ to be used in scenarios where the writer thread runs on control plane.
+
+* **Added Traffic Pattern Aware Power Control Library**
+
+ Added an experimental library. This extend Power Library and provide
+ empty_poll APIs. This feature measure how many times empty_poll are
+ executed per core, use the number of empty polls as a hint for system
+ power management.
+
+ See the :doc:`../prog_guide/power_man` section of the DPDK Programmers
+ Guide document for more information.
+
+* **Added JSON power policy interface for containers.**
+
+ Extended the Power Library and vm_power_manager sample app to allow power
+ policies to be submitted via a FIFO using JSON formatted strings. Previously
+ limited to Virtual Machines, this feature extends power policy functionality
+ to containers and host applications that need to have their cores frequency
+ controlled based on the rules contained in the policy.
+
+* **Added Telemetry API.**
+
+ Added the telemetry API which allows applications to transparently expose
+ their telemetry via a UNIX socket in JSON. The JSON can be consumed by any
+ Service Assurance agent, such as CollectD.
+
+* **Added ability to switch queue deferred start flag on testpmd app.**
+
+ Added a console command to testpmd app, giving ability to switch
+ ``rx_deferred_start`` or ``tx_deferred_start`` flag of the specified queue of
+ the specified port. The port must be stopped before the command call in order
+ to reconfigure queues.
+
+* **Add a new sample for vDPA**
+
+ The vdpa sample application creates vhost-user sockets by using the
+ vDPA backend. vDPA stands for vhost Data Path Acceleration which utilizes
+ virtio ring compatible devices to serve virtio driver directly to enable
+ datapath acceleration. As vDPA driver can help to set up vhost datapath,
+ this application doesn't need to launch dedicated worker threads for vhost
+ enqueue/dequeue operations.
+
+
+API Changes
+-----------
+
+.. This section should contain API changes. Sample format:
+
+ * Add a short 1-2 sentence description of the API change.
+ Use fixed width quotes for ``function_names`` or ``struct_names``.
+ Use the past tense.
+
+ This section is a comment. Do not overwrite or remove it.
+ Also, make sure to start the actual text at the margin.
+ =========================================================
+
+* eal: ``rte_memseg_list`` structure now has an additional flag indicating
+ whether the memseg list is externally allocated. This will have implications
+ for any users of memseg-walk-related functions, as they will now have to skip
+ externally allocated segments in most cases if the intent is to only iterate
+ over internal DPDK memory.
+ ``socket_id`` parameter across the entire DPDK has gained additional meaning,
+ as some socket ID's will now be representing externally allocated memory. No
+ changes will be required for existing code as backwards compatibility will be
+ kept, and those who do not use this feature will not see these extra socket
+ ID's. Any new API's must not check socket ID parameters themselves, and must
+ instead leave it to the memory subsystem to decide whether socket ID is a
+ valid one.
+
+* eal: The following devargs functions, which were deprecated in 18.05,
+ were removed in 18.11:
+ ``rte_eal_parse_devargs_str()``, ``rte_eal_devargs_add()``,
+ ``rte_eal_devargs_type_count()``, and ``rte_eal_devargs_dump()``.
+
+* eal: The parameters of the function ``rte_devargs_remove()`` have changed
+ from bus and device names to ``struct rte_devargs``.
+
+* eal: The deprecated functions attach/detach were removed in 18.11.
+ ``rte_eal_dev_attach`` can be replaced by
+ ``rte_dev_probe`` or ``rte_eal_hotplug_add``.
+ ``rte_eal_dev_detach`` can be replaced by
+ ``rte_dev_remove`` or ``rte_eal_hotplug_remove``.
+
+* eal: The scope of ``rte_eal_hotplug_add()``/``rte_dev_probe()``
+ and ``rte_eal_hotplug_remove()``/``rte_dev_remove()`` is extended.
+ In multi-process model, they will guarantee that the device is
+ attached or detached on all processes.
+
+* mbuf: The ``__rte_mbuf_raw_free()`` and ``__rte_pktmbuf_prefree_seg()``
+ functions were deprecated since 17.05 and are replaced by
+ ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()``.
+
+* ethdev: The deprecated functions attach/detach were removed in 18.11.
+ ``rte_eth_dev_attach`` can be replaced by ``RTE_ETH_FOREACH_MATCHING_DEV``
+ and ``rte_dev_probe`` or ``rte_eal_hotplug_add``.
+ ``rte_eth_dev_detach`` can be replaced by
+ ``rte_dev_remove`` or ``rte_eal_hotplug_remove``.
+
+* ethdev: A call to ``rte_eth_dev_release_port()`` has been added in
+ ``rte_eth_dev_close()``. As a consequence, a closed port is freed
+ and seen as invalid because of its state ``RTE_ETH_DEV_UNUSED``.
+ This new behaviour is enabled per driver for a migration period.
+
+* A new device flag, RTE_ETH_DEV_NOLIVE_MAC_ADDR, changes the order of
+ actions inside rte_eth_dev_start regarding MAC set. Some NICs do not
+ support MAC changes once the port has started and with this new device
+ flag the MAC can be properly configured in any case. This is particularly
+ important for bonding.
+
+* The default behaviour of CRC strip offload changed. Without any specific Rx
+ offload flag, default behavior by PMD is now to strip CRC.
+ DEV_RX_OFFLOAD_CRC_STRIP offload flag has been removed.
+ To request keeping CRC, application should set ``DEV_RX_OFFLOAD_KEEP_CRC`` Rx
+ offload.

+ABI Changes
+-----------
+

+
+ * Add a short 1-2 sentence description of the ABI change
+ that was announced in the previous releases and made in this release.
+ Use fixed width quotes for ``function_names`` or ``struct_names``.
+ Use the past tense.

+ This section is a comment. Do not overwrite or remove it.
+ Also, make sure to start the actual text at the margin.
+ =========================================================
+
+* eal: added ``legacy_mem`` and ``single_file_segments`` values to
+ ``rte_config`` structure on account of improving DPDK usability when
+ using either ``--legacy-mem`` or ``--single-file-segments`` flags.
+
+* eal: EAL library ABI version was changed due to previously announced work on
+ supporting external memory in DPDK:
+ - structure ``rte_memseg_list`` now has a new field indicating length
+ of memory addressed by the segment list
+ - structure ``rte_memseg_list`` now has a new flag indicating whether
+ the memseg list refers to external memory
+ - structure ``rte_malloc_heap`` now has a new field indicating socket
+ ID the malloc heap belongs to
+ - structure ``rte_mem_config`` has had its ``malloc_heaps`` array
+ resized from ``RTE_MAX_NUMA_NODES`` to ``RTE_MAX_HEAPS`` value
+ - structure ``rte_malloc_heap`` now has a ``heap_name`` member
+ - structure ``rte_eal_memconfig`` has been extended to contain next
+ socket ID for externally allocated segments
+
+* eal: Added ``dma_maskbits`` to ``rte_mem_config`` for keeping more restricted
+ dma mask based on devices addressing limitations.
+
+* eal: The structure ``rte_device`` got a new field to reference a ``rte_bus``.
+ It is changing the size of the ``struct rte_device`` and the inherited
+ device structures of all buses.

Overview
--------
-The Kernel NIC Interface sample application uses two threads in user space for each physical NIC port being used,
-and allocates one or more KNI device for each physical NIC port with kernel module's support.
-For a physical NIC port, one thread reads from the port and writes to KNI devices,
-and another thread reads from KNI devices and writes the data unmodified to the physical NIC port.
-It is recommended to configure one KNI device for each physical NIC port.
-If configured with more than one KNI devices for a physical NIC port,

Compiling the Application
-------------------------
To compile the sample application see :doc:`compiling`.
-The application is located in the ``kni`` sub-directory.
+The application is located in the ``examples/kni`` sub-directory.
.. note::
This application is intended as a linuxapp only.
-Loading the Kernel Module
--------------------------
+Running the kni Example Application
+-----------------------------------
-Loading the KNI kernel module without any parameter is the typical way a DPDK application
-gets packets into and out of the kernel net stack.
-This way, only one kernel thread is created for all KNI devices for packet receiving in kernel side:
+The ``kni`` example application requires a number of command line options:
.. code-block:: console
- #insmod rte_kni.ko
+ kni [EAL options] -- -p PORTMASK --config="(port,lcore_rx,lcore_tx[,lcore_kthread,...])[,(port,lcore_rx,lcore_tx[,lcore_kthread,...])]" [-P] [-m]
-Pinning the kernel thread to a specific core can be done using a taskset command such as following:
+Where:
-.. code-block:: console
+* ``-p PORTMASK``:
- #taskset -p 100000 `pgrep --fl kni_thread | awk '{print $1}'`
+ Hexadecimal bitmask of ports to configure.
-This command line tries to pin the specific kni_thread on the 20th lcore (lcore numbering starts at 0),
-which means it needs to check if that lcore is available on the board.
-This command must be sent after the application has been launched, as insmod does not start the kni thread.
+* ``--config="(port,lcore_rx,lcore_tx[,lcore_kthread,...])[,(port,lcore_rx,lcore_tx[,lcore_kthread,...])]"``:
-For optimum performance,
-the lcore in the mask must be selected to be on the same socket as the lcores used in the KNI application.
+ Determines which lcores the Rx and Tx DPDK tasks, and (optionally)
+ the KNI kernel thread(s) are bound to for each physical port.
-To provide flexibility of performance, the kernel module of the KNI,
-located in the kmod sub-directory of the DPDK target directory,
-can be loaded with parameter of kthread_mode as follows:
+* ``-P``:
-* #insmod rte_kni.ko kthread_mode=single
+ Optional flag to set all ports to promiscuous mode so that packets are
+ accepted regardless of the packet's Ethernet MAC destination address.
+ Without this option, only packets with the Ethernet MAC destination
+ address set to the Ethernet address of the port are accepted.
- This mode will create only one kernel thread for all KNI devices for packet receiving in kernel side.
- By default, it is in this single kernel thread mode.
- It can set core affinity for this kernel thread by using Linux command taskset.
+* ``-m``:
-* #insmod rte_kni.ko kthread_mode =multiple
+ Optional flag to enable monitoring and updating of the Ethernet
+ carrier state. With this option set, a thread will be started which
+ will periodically check the Ethernet link status of the physical
+ Ethernet ports and set the carrier state of the corresponding KNI
+ network interface to match it. This means that the KNI interface will
+ be disabled automatically when the Ethernet link goes down and enabled
+ when the Ethernet link goes up.
- This mode will create a kernel thread for each KNI device for packet receiving in kernel side.
- The core affinity of each kernel thread is set when creating the KNI device.
- The lcore ID for each kernel thread is provided in the command line of launching the application.
- Multiple kernel thread mode can provide scalable higher performance.
+Refer to *DPDK Getting Started Guide* for general information on running
+applications and the Environment Abstraction Layer (EAL) options.
-To measure the throughput in a loopback mode, the kernel module of the KNI,
-located in the kmod sub-directory of the DPDK target directory,
-can be loaded with parameters as follows:
+The ``-c coremask`` or ``-l corelist`` parameter of the EAL options must
+include the lcores specified by ``lcore_rx`` and ``lcore_tx`` for each port,
+but does not need to include lcores specified by ``lcore_kthread`` as those
+cores are used to pin the kernel threads in the ``rte_kni`` kernel module.
-* #insmod rte_kni.ko lo_mode=lo_mode_fifo
+The ``--config`` parameter must include a set of
+``(port,lcore_rx,lcore_tx,[lcore_kthread,...])`` values for each physical
+port specified in the ``-p PORTMASK`` parameter.
- This loopback mode will involve ring enqueue/dequeue operations in kernel space.
+The optional ``lcore_kthread`` lcore ID parameter in ``--config`` can be
+specified zero, one or more times for each physical port.
-* #insmod rte_kni.ko lo_mode=lo_mode_fifo_skb
+If no lcore ID is specified for ``lcore_kthread``, one KNI interface will
+be created for the physical port ``port`` and the KNI kernel thread(s)
+will have no specific core affinity.
- This loopback mode will involve ring enqueue/dequeue operations and sk buffer copies in kernel space.
+If one or more lcore IDs are specified for ``lcore_kthread``, a KNI interface
+will be created for each lcore ID specified, bound to the physical port
+``port``. If the ``rte_kni`` kernel module is loaded in :ref:`multiple
+kernel thread <kni_kernel_thread_mode>` mode, a kernel thread will be created
+for each KNI interface and bound to the specified core. If the ``rte_kni``
+kernel module is loaded in :ref:`single kernel thread <kni_kernel_thread_mode>`
+mode, only one kernel thread is started for all KNI interfaces. The kernel
+thread will be bound to the first ``lcore_kthread`` lcore ID specified.
-Running the Application
------------------------
+Example Configurations
+~~~~~~~~~~~~~~~~~~~~~~~
-The application requires a number of command line options:
+The following commands will first load the ``rte_kni`` kernel module in
+:ref:`multiple kernel thread <kni_kernel_thread_mode>` mode. The ``kni``
+application is then started using two ports; Port 0 uses lcore 4 for the
+Rx task, lcore 6 for the Tx task, and will create a single KNI interface
+``vEth0_0`` with the kernel thread bound to lcore 8. Port 1 uses lcore
+5 for the Rx task, lcore 7 for the Tx task, and will create a single KNI
+interface ``vEth1_0`` with the kernel thread bound to lcore 9.
.. code-block:: console
- kni [EAL options] -- -P -p PORTMASK --config="(port,lcore_rx,lcore_tx[,lcore_kthread,...])[,port,lcore_rx,lcore_tx[,lcore_kthread,...]]"

-Where:
+ # rmmod rte_kni
+ # insmod kmod/rte_kni.ko kthread_mode=multiple
+ # ./build/kni -l 4-7 -n 4 -- -P -p 0x3 -m --config="(0,4,6,8),(1,5,7,9)"
-* -P: Set all ports to promiscuous mode so that packets are accepted regardless of the packet's Ethernet MAC destination address.
- Without this option, only packets with the Ethernet MAC destination address set to the Ethernet address of the port are accepted.
+The following example is identical, except an additional ``lcore_kthread``
+core is specified per physical port. In this case, ``kni`` will create
+four KNI interfaces: ``vEth0_0``/``vEth0_1`` bound to physical port 0 and
+``vEth1_0``/``vEth1_1`` bound to physical port 1.
-* -p PORTMASK: Hexadecimal bitmask of ports to configure.
+The kernel thread for each interface will be bound as follows:
-* --config="(port,lcore_rx, lcore_tx[,lcore_kthread, ...]) [, port,lcore_rx, lcore_tx[,lcore_kthread, ...]]":
- Determines which lcores of RX, TX, kernel thread are mapped to which ports.
+ * ``vEth0_0`` - bound to lcore 8.
+ * ``vEth0_1`` - bound to lcore 10.
+ * ``vEth1_0`` - bound to lcore 9.
+ * ``vEth1_1`` - bound to lcore 11
-Refer to *DPDK Getting Started Guide* for general information on running applications and the Environment Abstraction Layer (EAL) options.
+.. code-block:: console
-The -c coremask or -l corelist parameter of the EAL options should include the lcores indicated by the lcore_rx and lcore_tx,
-but does not need to include lcores indicated by lcore_kthread as they are used to pin the kernel thread on.
-The -p PORTMASK parameter should include the ports indicated by the port in --config, neither more nor less.
+ # rmmod rte_kni
+ # insmod kmod/rte_kni.ko kthread_mode=multiple
+ # ./build/kni -l 4-7 -n 4 -- -P -p 0x3 -m --config="(0,4,6,8,10),(1,5,7,9,11)"
-The lcore_kthread in --config can be configured none, one or more lcore IDs.
-In multiple kernel thread mode, if configured none, a KNI device will be allocated for each port,
-while no specific lcore affinity will be set for its kernel thread.
-If configured one or more lcore IDs, one or more KNI devices will be allocated for each port,
-while specific lcore affinity will be set for its kernel thread.
-In single kernel thread mode, if configured none, a KNI device will be allocated for each port.
-If configured one or more lcore IDs,
-one or more KNI devices will be allocated for each port while
-no lcore affinity will be set as there is only one kernel thread for all KNI devices.
+The following example can be used to test the interface between the ``kni``
+test application and the ``rte_kni`` kernel module. In this example,
+the ``rte_kni`` kernel module is loaded in :ref:`single kernel thread
+mode <kni_kernel_thread_mode>`, :ref:`loopback mode <kni_loopback_mode>`
+enabled, and the :ref:`default carrier state <kni_default_carrier_state>`
+is set to *on* so that the corresponding physical NIC port does not have
+to be connected in order to use the KNI interface. One KNI interface
+``vEth0_0`` is created for port 0 and one KNI interface ``vEth1_0`` is
+created for port 1. Since ``rte_kni`` is loaded in "single kernel thread"
+mode, the one kernel thread is bound to lcore 8.
-For example, to run the application with two ports served by six lcores, one lcore of RX, one lcore of TX,
-and one lcore of kernel thread for each port:
+Since the physical NIC ports are not being used, link monitoring can be
+disabled by **not** specifying the ``-m`` flag to ``kni``:
.. code-block:: console
- ./build/kni -l 4-7 -n 4 -- -P -p 0x3 --config="(0,4,6,8),(1,5,7,9)"
+ # rmmod rte_kni
+ # insmod kmod/rte_kni.ko lo_mode=lo_mode_fifo carrier=on
+ # ./build/kni -l 4-7 -n 4 -- -P -p 0x3 --config="(0,4,6,8),(1,5,7,9)"
KNI Operations
--------------
-Once the KNI application is started, one can use different Linux* commands to manage the net interfaces.
-If more than one KNI devices configured for a physical port,
-only the first KNI device will be paired to the physical device.
-Operations on other KNI devices will not affect the physical port handled in user space application.
+Once the ``kni`` application is started, the user can use the normal
+Linux commands to manage the KNI interfaces as if they were any other
+Linux network interface.
-Assigning an IP address:
+Enable KNI interface and assign an IP address:
.. code-block:: console
- #ifconfig vEth0_0 192.168.0.1
+ # ifconfig vEth0_0 192.168.0.1
-Displaying the NIC registers:
+Show KNI interface configuration and statistics:
.. code-block:: console
- #ethtool -d vEth0_0
+ # ifconfig vEth0_0
+
+The user can also check and reset the packet statistics inside the ``kni``
+application by sending the app the USR1 and USR2 signals:
+
+.. code-block:: console
+
+ # Print statistics
+ # kill -SIGUSR1 `pidof kni`
+
+ # Zero statistics
+ # kill -SIGUSR2 `pidof kni`
-Dumping the network traffic:
+Dump network traffic:
.. code-block:: console
- #tcpdump -i vEth0_0
+ # tcpdump -i vEth0_0
+
+The normal Linux commands can also be used to change the MAC address and
+MTU size used by the physical NIC which corresponds to the KNI interface.
+However, if more than one KNI interface is configured for a physical port,
+these commands will only work on the first KNI interface for that port.
Change the MAC address:
.. code-block:: console
- #ifconfig vEth0_0 hw ether 0C:01:02:03:04:08
+ # ifconfig vEth0_0 hw ether 0C:01:02:03:04:08
+
+Change the MTU size:
+
+.. code-block:: console
+
+ # ifconfig vEth0_0 mtu 1450
+
+If DPDK is compiled with ``CONFIG_RTE_KNI_KMOD_ETHTOOL=y`` and an Intel
+NIC is used, the user can use ``ethtool`` on the KNI interface as if it
+were a normal Linux kernel interface.
+
+Displaying the NIC registers:
+
+.. code-block:: console
+
+ # ethtool -d vEth0_0
-When the DPDK userspace application is closed, all the KNI devices are deleted from Linux*.
+When the ``kni`` application is closed, all the KNI interfaces are deleted
+from the Linux kernel.

+Vdpa Sample Application
+=======================
+
+The vdpa sample application creates vhost-user sockets by using the
+vDPA backend. vDPA stands for vhost Data Path Acceleration which utilizes
+virtio ring compatible devices to serve virtio driver directly to enable
+datapath acceleration. As vDPA driver can help to set up vhost datapath,
+this application doesn't need to launch dedicated worker threads for vhost
+enqueue/dequeue operations.
+
+Testing steps
+-------------
+
+This section shows the steps of how to start VMs with vDPA vhost-user
+backend and verify network connection & live migration.
+
+Build
+~~~~~
+
+To compile the sample application see :doc:`compiling`.
+
+The application is located in the ``vdpa`` sub-directory.
+
+Start the vdpa example
+~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+ ./vdpa [EAL options] -- [--client] [--interactive|-i] or [--iface SOCKET_PATH]
+
+where
+
+* --client means running vdpa app in client mode, in the client mode, QEMU needs
+ to run as the server mode and take charge of socket file creation.
+* --iface specifies the path prefix of the UNIX domain socket file, e.g.
+ /tmp/vhost-user-, then the socket files will be named as /tmp/vhost-user-<n>
+ (n starts from 0).
+* --interactive means run the vdpa sample in interactive mode, currently 4
+ internal cmds are supported:
+
+ 1. help: show help message
+ 2. list: list all available vdpa devices
+ 3. create: create a new vdpa port with socket file and vdpa device address
+ 4. quit: unregister vhost driver and exit the application
+
+Take IFCVF driver for example:
+
+.. code-block:: console
+
+ ./vdpa -c 0x2 -n 4 --socket-mem 1024,1024 \
+ -w 0000:06:00.3,vdpa=1 -w 0000:06:00.4,vdpa=1 \
+ -- --interactive
+
+.. note::
+ Here 0000:06:00.3 and 0000:06:00.4 refer to virtio ring compatible devices,
+ and we need to bind vfio-pci to them before running vdpa sample.
+
+ * modprobe vfio-pci
+ * ./usertools/dpdk-devbind.py -b vfio-pci 06:00.3 06:00.4
+
+Then we can create 2 vdpa ports in interactive cmdline.
+
+.. code-block:: console
+
+ vdpa> list
+ device id device address queue num supported features
+ 0 0000:06:00.3 1 0x14c238020
+ 1 0000:06:00.4 1 0x14c238020
+ 2 0000:06:00.5 1 0x14c238020
+
+ vdpa> create /tmp/vdpa-socket0 0000:06:00.3
+ vdpa> create /tmp/vdpa-socket1 0000:06:00.4
+
+.. _vdpa_app_run_vm:
+
+Start the VMs
+~~~~~~~~~~~~~
+
+.. code-block:: console
+
+ qemu-system-x86_64 -cpu host -enable-kvm \
+ <snip>
+ -mem-prealloc \
+ -chardev socket,id=char0,path=<socket_file created in above steps> \
+ -netdev type=vhost-user,id=vdpa,chardev=char0 \
+ -device virtio-net-pci,netdev=vdpa,mac=00:aa:bb:cc:dd:ee,page-per-vq=on \
+
+After the VMs launches, we can login the VMs and configure the ip, verify the
+network connection via ping or netperf.
+
+.. note::
+ Suggest to use QEMU 3.0.0 which extends vhost-user for vDPA.
+
+Live Migration
+~~~~~~~~~~~~~~
+vDPA supports cross-backend live migration, user can migrate SW vhost backend
+VM to vDPA backend VM and vice versa. Here are the detailed steps. Assume A is
+the source host with SW vhost VM and B is the destination host with vDPA.
+
+1. Start vdpa sample and launch a VM with exact same parameters as the VM on A,
+ in migration-listen mode:
+
+.. code-block:: console
+
+ B: <qemu-command-line> -incoming tcp:0:4444 (or other PORT))
+
+2. Start the migration (on source host):
+
+.. code-block:: console
+
+ A: (qemu) migrate -d tcp:<B ip>:4444 (or other PORT)
+
+3. Check the status (on source host):
+
+.. code-block:: console
+
+ A: (qemu) info migrate

+
+JSON API
+~~~~~~~~
+
+In addition to the command line interface for host command and a virtio-serial
+interface for VM power policies, there is also a JSON interface through which
+power commands and policies can be sent. This functionality adds a dependency
+on the Jansson library, and the Jansson development package must be installed
+on the system before the JSON parsing functionality is included in the app.
+This is achieved by:
+
+ .. code-block:: javascript
+
+ apt-get install libjansson-dev
+
+The command and package name may be different depending on your operating
+system. It's worth noting that the app will successfully build without this
+package present, but a warning is shown during compilation, and the JSON
+parsing functionality will not be present in the app.
+
+Sending a command or policy to the power manager application is achieved by
+simply opening a fifo file, writing a JSON string to that fifo, and closing
+the file.
+
+The fifo is at /tmp/powermonitor/fifo
+
+The jason string can be a policy or instruction, and takes the following
+format:
+
+ .. code-block:: javascript
+
+ {"packet_type": {
+ "pair_1": value,
+ "pair_2": value
+ }}
+
+The 'packet_type' header can contain one of two values, depending on
+whether a policy or power command is being sent. The two possible values are
+"policy" and "instruction", and the expected name-value pairs is different
+depending on which type is being sent.
+
+The pairs are the format of standard JSON name-value pairs. The value type
+varies between the different name/value pairs, and may be integers, strings,
+arrays, etc. Examples of policies follow later in this document. The allowed
+names and value types are as follows:
+
+
+:Pair Name: "name"
+:Description: Name of the VM or Host. Allows the parser to associate the
+ policy with the relevant VM or Host OS.
+:Type: string
