+
+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the GNU make system (gmake)
+to build on FreeBSD. Optionally, gcc may also be used in place of clang
+to build the DPDK, in which case it too must be installed prior to
+compiling the DPDK. The installation of these tools is covered in this
+section.
+
+Compiling the DPDK requires the FreeBSD kernel sources, which should be
+included during the installation of FreeBSD on the development platform.
+The DPDK also requires the use of FreeBSD ports to compile and function.
+
+To use the FreeBSD ports system, it is required to update and extract the FreeBSD
+ports tree by issuing the following commands:
+
+.. code-block:: console
+
+ portsnap fetch
+ portsnap extract
+
+If the environment requires proxies for external communication, these can be set
+using:
+
+.. code-block:: console
+
+ setenv http_proxy <my_proxy_host>:<port>
+ setenv ftp_proxy <my_proxy_host>:<port>
+
+The FreeBSD ports below need to be installed prior to building the DPDK.
+In general these can be installed using the following set of commands::
+
+ cd /usr/ports/<port_location>
+
+ make config-recursive
+
+ make install
+
+ make clean
+
+Each port location can be found using::
+
+ whereis <port_name>
+
+The ports required and their locations are as follows:
+
+* dialog4ports: ``/usr/ports/ports-mgmt/dialog4ports``
+
+* GNU make(gmake): ``/usr/ports/devel/gmake``
+
+* coreutils: ``/usr/ports/sysutils/coreutils``
+
+For compiling and using the DPDK with gcc, the compiler must be installed
+from the ports collection:
+
+* gcc: version 4.8 is recommended ``/usr/ports/lang/gcc48``.
+ Ensure that ``CPU_OPTS`` is selected (default is OFF).
+
+When running the make config-recursive command, a dialog may be presented to the
+user. For the installation of the DPDK, the default options were used.
+
+.. note::
+
+ To avoid multiple dialogs being presented to the user during make install,
+ it is advisable before running the make install command to re-run the
+ make config-recursive command until no more dialogs are seen.
+
+
+Install the DPDK and Browse Sources
+-----------------------------------
+
+First, uncompress the archive and move to the DPDK source directory:
+
+.. code-block:: console
+
+ unzip DPDK-<version>.zip
+ cd DPDK-<version>
+
+ ls
+ app/ config/ examples/ lib/ LICENSE.GPL LICENSE.LGPL Makefile
+ mk/ scripts/ tools/
+
+The DPDK is composed of several directories:
+
+* lib: Source code of DPDK libraries
+
+* app: Source code of DPDK applications (automatic tests)
+
+* examples: Source code of DPDK applications
+
+* config, tools, scripts, mk: Framework-related makefiles, scripts and configuration
+
+Installation of the DPDK Target Environments
+--------------------------------------------
+
+The format of a DPDK target is::
+
+ ARCH-MACHINE-EXECENV-TOOLCHAIN
+
+Where:
+
+* ``ARCH`` is: ``x86_64``
+
+* ``MACHINE`` is: ``native``
+
+* ``EXECENV`` is: ``bsdapp``
+
+* ``TOOLCHAIN`` is: ``gcc`` | ``clang``
+
+The configuration files for the DPDK targets can be found in the DPDK/config
+directory in the form of::
+
+ defconfig_ARCH-MACHINE-EXECENV-TOOLCHAIN
+
+.. note::
+
+ Configuration files are provided with the ``RTE_MACHINE`` optimization level set.
+ Within the configuration files, the ``RTE_MACHINE`` configuration value is set
+ to native, which means that the compiled software is tuned for the platform
+ on which it is built. For more information on this setting, and its
+ possible values, see the *DPDK Programmers Guide*.
+
+To make the target, use ``gmake install T=<target>``.
+
+For example to compile for FreeBSD use:
+
+.. code-block:: console
+
+ gmake install T=x86_64-native-bsdapp-clang
+
+.. note::
+
+ If the compiler binary to be used does not correspond to that given in the
+ TOOLCHAIN part of the target, the compiler command may need to be explicitly
+ specified. For example, if compiling for gcc, where the gcc binary is called
+ gcc4.8, the command would need to be ``gmake install T=<target> CC=gcc4.8``.
+
+Browsing the Installed DPDK Environment Target
+----------------------------------------------
+
+Once a target is created, it contains all the libraries and header files for the
+DPDK environment that are required to build customer applications.
+In addition, the test and testpmd applications are built under the build/app
+directory, which may be used for testing. A kmod directory is also present that
+contains the kernel modules to install:
+
+.. code-block:: console
+
+ ls x86_64-native-bsdapp-gcc
+
+ app build hostapp include kmod lib Makefile
+
+
+.. _loading_contigmem:
+
+Loading the DPDK contigmem Module
+---------------------------------
+
+To run a DPDK application, physically contiguous memory is required.
+In the absence of non-transparent superpages, the included sources for the
+contigmem kernel module provides the ability to present contiguous blocks of
+memory for the DPDK to use. The contigmem module must be loaded into the
+running kernel before any DPDK is run. The module is found in the kmod
+sub-directory of the DPDK target directory.
+
+The amount of physically contiguous memory along with the number of physically
+contiguous blocks to be reserved by the module can be set at runtime prior to
+module loading using:
+
+.. code-block:: console
+
+ kenv hw.contigmem.num_buffers=n
+ kenv hw.contigmem.buffer_size=m
+
+The kernel environment variables can also be specified during boot by placing the
+following in ``/boot/loader.conf``::
+
+ hw.contigmem.num_buffers=n hw.contigmem.buffer_size=m
+
+The variables can be inspected using the following command:
+
+.. code-block:: console
+
+ sysctl -a hw.contigmem
+
+Where n is the number of blocks and m is the size in bytes of each area of
+contiguous memory. A default of two buffers of size 1073741824 bytes (1 Gigabyte)
+each is set during module load if they are not specified in the environment.
+
+The module can then be loaded using kldload (assuming that the current directory
+is the DPDK target directory):
+
+.. code-block:: console
+
+ kldload ./kmod/contigmem.ko
+
+It is advisable to include the loading of the contigmem module during the boot
+process to avoid issues with potential memory fragmentation during later system
+up time. This can be achieved by copying the module to the ``/boot/kernel/``
+directory and placing the following into ``/boot/loader.conf``::
+
+ contigmem_load="YES"
+
+.. note::
+
+ The contigmem_load directive should be placed after any definitions of
+ ``hw.contigmem.num_buffers`` and ``hw.contigmem.buffer_size`` if the default values
+ are not to be used.
+
+An error such as:
+
+.. code-block:: console
+
+ kldload: can't load ./x86_64-native-bsdapp-gcc/kmod/contigmem.ko:
+ Exec format error
+
+is generally attributed to not having enough contiguous memory
+available and can be verified via dmesg or ``/var/log/messages``:
+
+.. code-block:: console
+
+ kernel: contigmalloc failed for buffer <n>
+
+To avoid this error, reduce the number of buffers or the buffer size.
+
+.. _loading_nic_uio:
+
+Loading the DPDK nic_uio Module
+-------------------------------
+
+After loading the contigmem module, the ``nic_uio must`` also be loaded into the
+running kernel prior to running any DPDK application. This module must
+be loaded using the kldload command as shown below (assuming that the current
+directory is the DPDK target directory).
+
+.. code-block:: console
+
+ kldload ./kmod/nic_uio.ko
+
+.. note::
+
+ If the ports to be used are currently bound to a existing kernel driver
+ then the ``hw.nic_uio.bdfs sysctl`` value will need to be set before loading the
+ module. Setting this value is described in the next section below.
+
+Currently loaded modules can be seen by using the ``kldstat`` command and a module
+can be removed from the running kernel by using ``kldunload <module_name>``.
+
+To load the module during boot, copy the ``nic_uio`` module to ``/boot/kernel``
+and place the following into ``/boot/loader.conf``::
+
+ nic_uio_load="YES"
+
+.. note::
+
+ ``nic_uio_load="YES"`` must appear after the contigmem_load directive, if it exists.
+
+By default, the ``nic_uio`` module will take ownership of network ports if they are
+recognized DPDK devices and are not owned by another module. However, since
+the FreeBSD kernel includes support, either built-in, or via a separate driver
+module, for most network card devices, it is likely that the ports to be used are
+already bound to a driver other than ``nic_uio``. The following sub-section describe
+how to query and modify the device ownership of the ports to be used by
+DPDK applications.
+
+.. _binding_network_ports:
+
+Binding Network Ports to the nic_uio Module
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Device ownership can be viewed using the pciconf -l command. The example below shows
+four IntelĀ® 82599 network ports under ``if_ixgbe`` module ownership.
+
+.. code-block:: console
+
+ pciconf -l
+ ix0@pci0:1:0:0: class=0x020000 card=0x00038086 chip=0x10fb8086 rev=0x01 hdr=0x00
+ ix1@pci0:1:0:1: class=0x020000 card=0x00038086 chip=0x10fb8086 rev=0x01 hdr=0x00
+ ix2@pci0:2:0:0: class=0x020000 card=0x00038086 chip=0x10fb8086 rev=0x01 hdr=0x00
+ ix3@pci0:2:0:1: class=0x020000 card=0x00038086 chip=0x10fb8086 rev=0x01 hdr=0x00
+
+The first column constitutes three components:
+
+#. Device name: ``ixN``
+
+#. Unit name: ``pci0``
+
+#. Selector (Bus:Device:Function): ``1:0:0``
+
+Where no driver is associated with a device, the device name will be ``none``.
+
+By default, the FreeBSD kernel will include built-in drivers for the most common
+devices; a kernel rebuild would normally be required to either remove the drivers
+or configure them as loadable modules.
+
+To avoid building a custom kernel, the ``nic_uio`` module can detach a network port
+from its current device driver. This is achieved by setting the ``hw.nic_uio.bdfs``
+kernel environment variable prior to loading ``nic_uio``, as follows::
+
+ hw.nic_uio.bdfs="b:d:f,b:d:f,..."
+
+Where a comma separated list of selectors is set, the list must not contain any
+whitespace.
+
+For example to re-bind ``ix2@pci0:2:0:0`` and ``ix3@pci0:2:0:1`` to the ``nic_uio`` module
+upon loading, use the following command::
+
+ kenv hw.nic_uio.bdfs="2:0:0,2:0:1"
+
+The variable can also be specified during boot by placing the following into
+``/boot/loader.conf``, before the previously-described ``nic_uio_load`` line - as
+shown::
+
+ hw.nic_uio.bdfs="2:0:0,2:0:1"
+ nic_uio_load="YES"
+
+Binding Network Ports Back to their Original Kernel Driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the original driver for a network port has been compiled into the kernel,
+it is necessary to reboot FreeBSD to restore the original device binding. Before
+doing so, update or remove the ``hw.nic_uio.bdfs`` in ``/boot/loader.conf``.
+
+If rebinding to a driver that is a loadable module, the network port binding can
+be reset without rebooting. To do so, unload both the target kernel module and the
+``nic_uio`` module, modify or clear the ``hw.nic_uio.bdfs`` kernel environment (kenv)
+value, and reload the two drivers - first the original kernel driver, and then
+the ``nic_uio driver``. Note: the latter does not need to be reloaded unless there are
+ports that are still to be bound to it.
+
+Example commands to perform these steps are shown below:
+
+.. code-block:: console
+
+ kldunload nic_uio
+ kldunload <original_driver>
+
+ # To clear the value completely:
+ kenv -u hw.nic_uio.bdfs
+
+ # To update the list of ports to bind:
+ kenv hw.nic_uio.bdfs="b:d:f,b:d:f,..."
+
+ kldload <original_driver>
+
+ kldload nic_uio # optional

+
+.. _compiling_sample_apps:
+
+Compiling and Running Sample Applications
+=========================================
+
+The chapter describes how to compile and run applications in a DPDK
+environment. It also provides a pointer to where sample applications are stored.
+
+Compiling a Sample Application
+------------------------------
+
+Once a DPDK target environment directory has been created (such as
+``x86_64-native-bsdapp-clang``), it contains all libraries and header files required
+to build an application.
+
+When compiling an application in the FreeBSD environment on the DPDK,
+the following variables must be exported:
+
+* ``RTE_SDK`` - Points to the DPDK installation directory.
+
+* ``RTE_TARGET`` - Points to the DPDK target environment directory.
+ For FreeBSD, this is the ``x86_64-native-bsdapp-clang`` or
+ ``x86_64-native-bsdapp-gcc`` directory.
+
+The following is an example of creating the ``helloworld`` application, which runs
+in the DPDK FreeBSD environment. While the example demonstrates compiling
+using gcc version 4.8, compiling with clang will be similar, except that the ``CC=``
+parameter can probably be omitted. The ``helloworld`` example may be found in the
+``${RTE_SDK}/examples`` directory.
+
+The directory contains the ``main.c`` file. This file, when combined with the
+libraries in the DPDK target environment, calls the various functions to
+initialize the DPDK environment, then launches an entry point (dispatch
+application) for each core to be utilized. By default, the binary is generated
+in the build directory.
+
+.. code-block:: console
+
+ setenv RTE_SDK /home/user/DPDK
+ cd $(RTE_SDK)
+ cd examples/helloworld/
+ setenv RTE_SDK $HOME/DPDK
+ setenv RTE_TARGET x86_64-native-bsdapp-gcc
+
+ gmake CC=gcc48
+ CC main.o
+ LD helloworld
+ INSTALL-APP helloworld
+ INSTALL-MAP helloworld.map
+
+ ls build/app
+ helloworld helloworld.map
+
+.. note::
+
+ In the above example, ``helloworld`` was in the directory structure of the
+ DPDK. However, it could have been located outside the directory
+ structure to keep the DPDK structure intact. In the following case,
+ the ``helloworld`` application is copied to a new directory as a new starting
+ point.
+
+.. code-block:: console
+
+ setenv RTE_SDK /home/user/DPDK
+ cp -r $(RTE_SDK)/examples/helloworld my_rte_app
+ cd my_rte_app/
+ setenv RTE_TARGET x86_64-native-bsdapp-gcc
+
+ gmake CC=gcc48
+ CC main.o
+ LD helloworld
+ INSTALL-APP helloworld
+ INSTALL-MAP helloworld.map
+
+.. _running_sample_app:
+
+Running a Sample Application
+----------------------------
+
+#. The ``contigmem`` and ``nic_uio`` modules must be set up prior to running an application.
+
+#. Any ports to be used by the application must be already bound to the ``nic_uio`` module,
+ as described in section :ref:`binding_network_ports`, prior to running the application.
+ The application is linked with the DPDK target environment's Environment
+ Abstraction Layer (EAL) library, which provides some options that are generic
+ to every DPDK application.
+
+The following is the list of options that can be given to the EAL:
+
+.. code-block:: console
+
+ ./rte-app -c COREMASK [-n NUM] [-b <domain:bus:devid.func>] \
+ [-r NUM] [-v] [--proc-type <primary|secondary|auto>]
+
+.. note::
+
+ EAL has a common interface between all operating systems and is based on the
+ Linux notation for PCI devices. For example, a FreeBSD device selector of
+ ``pci0:2:0:1`` is referred to as ``02:00.1`` in EAL.
+
+The EAL options for FreeBSD are as follows:
+
+* ``-c COREMASK``:
+ A hexadecimal bit mask of the cores to run on. Note that core numbering
+ can change between platforms and should be determined beforehand.
+
+* ``-n NUM``:
+ Number of memory channels per processor socket.
+
+* ``-b <domain:bus:devid.func>``:
+ Blacklisting of ports; prevent EAL from using specified PCI device
+ (multiple ``-b`` options are allowed).
+
+* ``--use-device``:
+ Use the specified Ethernet device(s) only. Use comma-separate
+ ``[domain:]bus:devid.func`` values. Cannot be used with ``-b`` option.
+
+* ``-r NUM``:
+ Number of memory ranks.
+
+* ``-v``:
+ Display version information on startup.
+
+* ``--proc-type``:
+ The type of process instance.
+
+Other options, specific to Linux and are not supported under FreeBSD are as follows:
+
+* ``socket-mem``:
+ Memory to allocate from hugepages on specific sockets.
+
+* ``--huge-dir``:
+ The directory where hugetlbfs is mounted.
+
+* ``--file-prefix``:
+ The prefix text used for hugepage filenames.
+
+* ``-m MB``:
+ Memory to allocate from hugepages, regardless of processor socket.
+ It is recommended that ``--socket-mem`` be used instead of this option.
+
+The ``-c`` option is mandatory; the others are optional.
+
+Copy the DPDK application binary to your target, then run the application
+as follows (assuming the platform has four memory channels, and that cores 0-3
+are present and are to be used for running the application)::
+
+ ./helloworld -c f -n 4
+
+.. note::
+
+ The ``--proc-type`` and ``--file-prefix`` EAL options are used for running multiple
+ DPDK processes. See the "Multi-process Sample Application" chapter
+ in the *DPDK Sample Applications User Guide and the DPDK
+ Programmers Guide* for more details.
+
+.. _running_non_root:
+
+Running DPDK Applications Without Root Privileges
+-------------------------------------------------
+
+Although applications using the DPDK use network ports and other hardware
+resources directly, with a number of small permission adjustments, it is possible
+to run these applications as a user other than "root". To do so, the ownership,
+or permissions, on the following file system objects should be adjusted to ensure
+that the user account being used to run the DPDK application has access
+to them:
+
+* The userspace-io device files in ``/dev``, for example, ``/dev/uio0``, ``/dev/uio1``, and so on
+
+* The userspace contiguous memory device: ``/dev/contigmem``
+
+.. note::
+
+ Please refer to the DPDK Release Notes for supported applications.

+
+Installing DPDK from the Ports Collection
+=========================================
+
+The easiest way to get up and running with the DPDK on FreeBSD is to
+install it from the ports collection. Details of getting and using the ports
+collection are documented in the
+`FreeBSD Handbook <http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html>`_.
+
+.. note::
+
+ Testing has been performed using FreeBSD 10.0-RELEASE (x86_64) and requires the
+ installation of the kernel sources, which should be included during the
+ installation of FreeBSD.
+
+Installing the DPDK FreeBSD Port
+--------------------------------
+
+On a system with the ports collection installed in ``/usr/ports``, the DPDK
+can be installed using the commands:
+
+.. code-block:: console
+
+ cd /usr/ports/net/dpdk
+
+ make install
+
+After the installation of the DPDK port, instructions will be printed on
+how to install the kernel modules required to use the DPDK. A more
+complete version of these instructions can be found in the sections
+:ref:`loading_contigmem` and :ref:`loading_nic_uio`. Normally, lines like
+those below would be added to the file ``/boot/loader.conf``.
+
+.. code-block:: console
+
+ # Reserve 2 x 1G blocks of contiguous memory using contigmem driver:
+ hw.contigmem.num_buffers=2
+ hw.contigmem.buffer_size=1073741824
+ contigmem_load="YES"
+
+ # Identify NIC devices for DPDK apps to use and load nic_uio driver:
+ hw.nic_uio.bdfs="2:0:0,2:0:1"
+ nic_uio_load="YES"
+
+Compiling and Running the Example Applications
+----------------------------------------------
+
+When the DPDK has been installed from the ports collection it installs
+its example applications in ``/usr/local/share/dpdk/examples`` - also accessible via
+symlink as ``/usr/local/share/examples/dpdk``. These examples can be compiled and
+run as described in :ref:`compiling_sample_apps`. In this case, the required
+environmental variables should be set as below:
+
+* ``RTE_SDK=/usr/local/share/dpdk``
+
+* ``RTE_TARGET=x86_64-native-bsdapp-clang``
+
+.. note::
+
+ To install a copy of the DPDK compiled using gcc, please download the
+ official DPDK package from http://dpdk.org/ and install manually using
+ the instructions given in the next chapter, :ref:`building_from_source`
+
+An example application can therefore be copied to a user's home directory and
+compiled and run as below:
+
+.. code-block:: console
+
+ export RTE_SDK=/usr/local/share/dpdk
+
+ export RTE_TARGET=x86_64-native-bsdapp-clang
+
+ cp -r /usr/local/share/dpdk/examples/helloworld .
+
+ cd helloworld/
+
+ gmake
+ CC main.o
+ LD helloworld
+ INSTALL-APP helloworld
+ INSTALL-MAP helloworld.map
+
+ sudo ./build/helloworld -c F -n 2

+Introduction
+============
+
+This document contains instructions for installing and configuring the
+Data Plane Development Kit (DPDK) software. It is designed to get customers
+up and running quickly and describes how to compile and run a
+DPDK application in a FreeBSD application (bsdapp) environment, without going
+deeply into detail.
+
+For a comprehensive guide to installing and using FreeBSD, the following
+handbook is available from the FreeBSD Documentation Project:
+`FreeBSD Handbook <http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html>`_.
+
+.. note::
+
+ The DPDK is now available as part of the FreeBSD ports collection.
+ Installing via the ports collection infrastructure is now the recommended
+ way to install the DPDK on FreeBSD, and is documented in the
+ next chapter, :ref:`install_from_ports`.
