+
+MRVL Poll Mode Driver
+======================
+
+The MRVL PMD (librte_pmd_mrvl) provides poll mode driver support
+for the Marvell PPv2 (Packet Processor v2) 1/10 Gbps adapter.
+
+Detailed information about SoCs that use PPv2 can be obtained here:
+
+* https://www.marvell.com/embedded-processors/armada-70xx/
+* https://www.marvell.com/embedded-processors/armada-80xx/
+
+.. 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 MRVL PMD are:
+
+- Speed capabilities
+- Link status
+- Queue start/stop
+- MTU update
+- Jumbo frame
+- Promiscuous mode
+- Allmulticast mode
+- Unicast MAC filter
+- Multicast MAC filter
+- RSS hash
+- VLAN filter
+- CRC offload
+- L3 checksum offload
+- L4 checksum offload
+- Packet type parsing
+- Basic stats
+- QoS
+
+
+Limitations
+-----------
+
+- Number of lcores is limited to 9 by MUSDK internal design. If more lcores
+ need to be allocated, locking will have to be considered. Number of available
+ lcores can be changed via ``MRVL_MUSDK_HIFS_RESERVED`` define in
+ ``mrvl_ethdev.c`` source file.
+
+- Flushing vlans added for filtering is not possible due to MUSDK missing
+ functionality. Current workaround is to reset board so that PPv2 has a
+ chance to start in a sane state.
+
+
+Prerequisites
+-------------
+
+- Custom Linux Kernel sources available
+ `here <https://github.com/MarvellEmbeddedProcessors/linux-marvell/tree/linux-4.4.52-armada-17.08>`__.
+
+- Out of tree `mvpp2x_sysfs` kernel module sources available
+ `here <https://github.com/MarvellEmbeddedProcessors/mvpp2x-marvell/tree/mvpp2x-armada-17.08>`__.
+
+- MUSDK (Marvell User-Space SDK) sources available
+ `here <https://github.com/MarvellEmbeddedProcessors/musdk-marvell/tree/musdk-armada-17.08>`__.
+
+ MUSDK is a light-weight library that provides direct access to Marvell's
+ PPv2 (Packet Processor v2). 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-bpool-dma=64
+
+- DPDK environment
+
+ Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup
+ DPDK environment.
+
+
+Config File Options
+-------------------
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_MRVL_PMD`` (default ``n``)
+
+ Toggle compilation of the librte_pmd_mrvl driver.
+
+- ``CONFIG_RTE_LIBRTE_MRVL_DEBUG`` (default ``n``)
+
+ Toggle display of debugging messages.
+
+- ``CONFIG_RTE_MRVL_MUSDK_DMA_MEMSIZE`` (default ``41943040``)
+
+ Size in bytes of the contiguous memory region that MUSDK will allocate
+ for run-time DMA-able data buffers.
+
+
+QoS Configuration
+-----------------
+
+QoS configuration is done through external configuration file. Path to the
+file must be given as `cfg` in driver's vdev parameter list.
+
+Configuration syntax
+~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+ [port <portnum> default]
+ default_tc = <default_tc>
+ qos_mode = <qos_priority>
+
+ [port <portnum> tc <traffic_class>]
+ rxq = <rx_queue_list>
+ pcp = <pcp_list>
+ dscp = <dscp_list>
+
+ [port <portnum> tc <traffic_class>]
+ rxq = <rx_queue_list>
+ pcp = <pcp_list>
+ dscp = <dscp_list>
+
+Where:
+
+- ``<portnum>``: DPDK Port number (0..n).
+
+- ``<default_tc>``: Default traffic class (e.g. 0)
+
+- ``<qos_priority>``: QoS priority for mapping (`ip`, `vlan`, `ip/vlan` or `vlan/ip`).
+
+- ``<traffic_class>``: Traffic Class to be configured.
+
+- ``<rx_queue_list>``: List of DPDK RX queues (e.g. 0 1 3-4)
+
+- ``<pcp_list>``: List of PCP values to handle in particular TC (e.g. 0 1 3-4 7).
+
+- ``<dscp_list>``: List of DSCP values to handle in particular TC (e.g. 0-12 32-48 63).
+
+Setting PCP/DSCP values for the default TC is not required. All PCP/DSCP
+values not assigned explicitly to particular TC will be handled by the
+default TC.
+
+Configuration file example
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: console
+
+ [port 0 default]
+ default_tc = 0
+ qos_mode = ip
+
+ [port 0 tc 0]
+ rxq = 0 1
+
+ [port 0 tc 1]
+ rxq = 2
+ pcp = 5 6 7
+ dscp = 26-38
+
+ [port 1 default]
+ default_tc = 0
+ qos_mode = vlan/ip
+
+ [port 1 tc 0]
+ rxq = 0
+
+ [port 1 tc 1]
+ rxq = 1 2
+ pcp = 5 6 7
+ dscp = 26-38
+
+Usage example
+^^^^^^^^^^^^^
+
+.. code-block:: console
+
+ ./testpmd --vdev=eth_mrvl,iface=eth0,iface=eth2,cfg=/home/user/mrvl.conf \
+ -c 7 -- -i -a --disable-hw-vlan-strip --rxq=2
+
+
+Building DPDK
+-------------
+
+Driver needs precompiled MUSDK library during compilation. Please consult
+``doc/musdk_get_started.txt`` for the detailed build instructions.
+
+Before the DPDK build process the environmental variable ``LIBMUSDK_PATH`` with
+the path to the MUSDK installation directory needs to be exported.
+
+
+Usage Example
+-------------
+
+MRVL PMD requires extra out of tree kernel modules to function properly.
+`musdk_uio` and `mv_pp_uio` sources are part of the MUSDK. Please consult
+``doc/musdk_get_started.txt`` for the detailed build instructions.
+For `mvpp2x_sysfs` please consult ``Documentation/pp22_sysfs.txt`` for the
+detailed build instructions.
+
+.. code-block:: console
+
+ insmod musdk_uio.ko
+ insmod mv_pp_uio.ko
+ insmod mvpp2x_sysfs.ko
+
+Additionally interfaces used by DPDK application need to be put up:
+
+.. code-block:: console
+
+ ip link set eth0 up
+ ip link set eth1 up
+
+In order to run testpmd example application following command can be used:
+
+.. code-block:: console
+
+ ./testpmd --vdev=eth_mrvl,iface=eth0,iface=eth2 -c 7 -- \
+ --burst=128 --txd=2048 --rxd=1024 --rxq=2 --txq=2 --nb-cores=2 \
+ -i -a --disable-hw-vlan-strip --rss-udp
