-System Requirements
-===================
-
-This chapter describes the packages required to compile the Intel® DPDK.
-
-Compilationofthe Intel® DPDK
-----------------------------
-
-.. note::
-
- The Intel® DPDK and its applications requires the GNU make system (gmake)
- and the GNU Compiler Collection (gcc) to build on FreeBSD*. The
- installation of these tools is covered in this section.
-
-**Required Tools:**
-
-.. note::
-
- Testing has been performed using FreeBSD* 9.2-RELEASE (x86_64), FreeBSD*
- 10.0-RELEASE (x86_64) and requires the installation of the kernel sources,
- which should be included during the installation of FreeBSD*. The Intel®
- 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
-
- root@host:~ # portsnap fetch
- root@host:~ # portsnap extract
-
-If the environment requires proxies for external communication, these can be set
-using:
-
-.. code-block:: console
-
- root@host:~ # setenv http_proxy <my_proxy_host>:<port>
- root@host:~ # setenv ftp_proxy <my_proxy_host>:<port>
-
-The FreeBSD* ports below need to be installed prior to building the Intel® 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:
-
-.. code-block:: console
-
- user@host:~ # whereis <port_name>
-
-The ports required and their locations are as follows:
-
-* dialog4ports
-
-* /usr/ports/ports-mgmt/dialog4ports
-
-* gcc: version 4.8 is recommended
-
-* /usr/ports/lang/gcc48
-
-* Ensure that CPU_OPTS is selected (default is OFF)
-
-* GNU make(gmake)
-
-* Installed automatically with gcc48
-
-* coreutils
-
-* /usr/ports/sysutils/coreutils
-
-* libexecinfo (Not required for FreeBSD* 10)
-
-* /usr/src/contrib/libexecinfo
-
-When running the make config-recursive command, a dialog may be presented to the
-user. For the installation of the Intel® 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.
-
-Running Intel® DPDK Applications
---------------------------------
-
-To run an Intel® 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 Intel® DPDK to use. Section 3.4, “Loading the Intel® DPDK
-Contigmem Module” on page 8 for details on the loading of this module.
-
-Using Intel® DPDK Contigmem Module
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The amount of physically contiguous memory along with the number of physically
-contiguous blocks can be set at runtime and prior to module loading using:
-
-.. code-block:: console
-
- root@host:~ # kenv hw.contigmem.num_buffers=n
- root@host:~ # 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
-
- root@host:~ # 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.
-
-.. note::
-
- The /boot/loader.conf file may not exist, but can be created as a root user
- and should be given permissions as follows:
-
-.. code-block:: console
-
- root@host:~ # chmod 644 /boot/loader.conf
