doc: add freebsd ports
Since the DPDK is now part of the BSD ports collection, we should recommend installing from ports as the best way to get it up and running. In order to achieve this, while still keeping the document readable, the chapter on system requirements has been moved to instead be a section within the chapter on compiling the DPDK outside of the ports collection. This move is necessary, since it covered a lot of detail on installing other ports required to build DPDK. These steps are not needed when installing DPDK itself from ports.

Compiling the Intel® DPDK Target from Source
|
||||
============================================
|
||||
|
||||
.. 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*. The Intel® DPDK also requires the use of FreeBSD*
|
||||
ports to compile and function.
|
||||
|
||||
System Requirements
|
||||
-------------------
|
||||
|
||||
The Intel® 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 Intel® DPDK, in which case it too must be installed prior to
|
||||
compiling the Intel® DPDK. The installation of these tools is covered in this
|
||||
section.
|
||||
|
||||
Compiling the Intel® DPDK requires the FreeBSD kernel sources, which should be
|
||||
included during the installation of FreeBSD* on the development platform.
|
||||
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
|
||||
|
||||
GNU make(gmake)
|
||||
/usr/ports/devel/gmake
|
||||
|
||||
coreutils
|
||||
/usr/ports/sysutils/coreutils
|
||||
|
||||
For compiling and using the Intel® DPDK with gcc, it too 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 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 kernel before any Intel® DPDK is run. The module is found in the kmod
|
||||
sub-directory of the Intel® DPDK target directory.

|
||||
|

||||
value, and reload the two drivers - first the original kernel driver, and then
|
||||
the nic_uio driver. [The latter does not need to be reloaded unless there are
|
||||
ports that are still to be bound to it].
|
||||
|
||||
Update or remove the hw.nic_uio.bdfs entry from /boot/loader.conf if specified

Installing Intel® DPDK from the Ports Collection
|
||||
================================================
|
||||
|
||||
The easiest way to get up and running with the Intel® 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 at:
|
||||
|
||||
https://www.freebsd.org/doc/handbook/ports-using.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 Intel® DPDK FreeBSD Port
|
||||
---------------------------------------
|
||||
|
||||
On a system with the ports collection installed in /usr/ports, the Intel® DPDK
|
||||
can be installed using the commands:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
root@host:~ # cd /usr/ports/net/dpdk
|
||||
|
||||
root@host:~ # make install
|
||||
|
||||
After the installation of the Intel® DPDK port, instructions will be printed on
|
||||
how to install the kernel modules required to use the Intel® 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 Intel® 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 Intel® 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 Intel® DPDK compiled using gcc, please download the
|
||||
official Intel® 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
|
||||
|
||||
user@host:~$ export RTE_SDK=/usr/local/share/dpdk
|
||||
|
||||
user@host:~$ export RTE_TARGET=x86_64-native-bsdapp-clang

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
|
||||
