README for setting up Pktgen with DPDK on Ubuntu 10.04 to 16.10 desktop, it should work on most Linux systems as long as the kernel has hugeTLB page support.

Note: Tested with Ubuntu 13.10 and up to 16.10 kernel versions Linux 3.5.0-25-generic #39-Ubuntu SMP Mon Feb 25 18:26:58 UTC 2013 x86_64

I am using Ubuntu 16.10 x86_64 (64 bit support) for running Pktgen-DPDK on a Crownpass Dual socket board running at 2.4GHz with 32GB of ram 16GB per socket. The current kernel version is 4.4.0-66-generic (as of 2017-04-01) support, but should work on just about any new Linux kernel version.

Currently using as of 2017-04-01 Ubuntu 16.10 Kernel 4.4.0-66-generic system.

To get hugeTLB page support your Linux kernel must be at least 2.6.33 and in the DPDK documents it talks about how you can upgrade your Linux kernel.

Here is another document on how to upgrade your Linux kernel. Ubuntu 10.04 is 2.6.32 by default so upgraded to kernel 2.6.34 using this HOWTO: http://usablesoftware.wordpress.com/2010/05/26/switch-to-a-newer-kernel-in-ubuntu-10-04/

The pktgen output display needs 132 columns and about 42 lines to display currentlyt. I am using an xterm of 132x42, but you can have a larger display and maybe a bit smaller. If you are displaying more then 4-6 ports then you will need a wider display. Pktgen allows you to view a set of ports if they do not all fit on the screen at one time via the 'page' command.

Type 'help' at the 'Pktgen>' prompt to see the complete Pktgen command line commands. Pktgen uses VT100 control codes or escape codes to display the screens, which means your terminal must support VT100. The Hyperterminal in windows is not going to work for Pktgen as it has a few problems with VT100 codes.

Pktgen has a number of modes to send packets single, range, random, sequeue and PCAP modes. Each mode has its own set of packet buffers and you must configure each mode to work correctly. The single packet mode is the information displayed at startup screen or when using the 'page main or page 0' command. The other screens can be accessed using 'page seq|range|rnd|pcap|stats' command.

The pktgen program as built can send up to 16 packets per port in a sequence and you can configure a port using the 'seq' pktgen command. A script file can be loaded from the shell command line via the -f option and you can 'load' a script file from within pktgen as well.

In the BIOS make sure the HPET High Precision Event Timer is enabled. Also make sure hyper-threading is enabled.

** NOTE ** On a 10GB NIC if the transceivers are not attached the screen updates will go very slow.

cd

git clone git://dpdk.org/dpdk.git

cd

git clone git://dpdk.org/pktgen-dpdk.git

`` ** Note ** The site dpdk.org you must also pull down DPDK repo as well. git://dpdk.org/dpdk

Will create a directory called Pktgen-DPDK in the current directory location. Using the above clone commands you will get DPDK and pktgen source files.

Make sure you have HUGE TLB support in the kernel with the following commands: ``

grep -i huge /boot/config-2.6.35-24-generic

CONFIG_HUGETLBFS=y CONFIG_HUGETLB_PAGE=y

grep -i huge /proc/meminfo

HugePages_Total:128 HugePages_Free: 128 HugePages_Rsvd:0 HugePages_Surp:0 Hugepagesize: 2048 kB `` NOTE: The values in Total and Free maybe different until you reboot the machine.

Two files in /etc must be setup to support huge TLBs. If you do not have hugeTLB support then you most likely need a newer kernel. ``

vi /etc/sysctl.conf

Add to the bottom of the file for 2M hugepages: vm.nr_hugepages=256 If you need more or less hugeTLB pages then you can change the value to a number you need it to be. In some cases pktgen needs a fair number of pages and making it too small will effect performance or pktgen will terminate on startup looking for more pages.

On Ubuntu 15.10 I noticed mounting /mnt/huge is not required as /dev/hugepages

is already mounted. Check your system and verify that /mnt/huge is required.

vi /etc/fstab

Add to the bottom of the file: huge /mnt/huge hugetlbfs defaults 0 0

mkdir /mnt/huge

chmod 777 /mnt/huge

`` Reboot your machine as the huge pages must be setup just after boot to make sure you have contiguous memory for the 2Meg pages, setting up 1G pages can also be done.

** Note: If you startup Eclipse or WR Workbench before starting pktgen the first time after reboot, pktgen will fail to load because it can not get all of the huge pages as eclipse has consumed some of the huge pages. If you did start eclipse or WR Workbench then you need to close that application first.

This is my current machine you will have a few different numbers depending on how your system was booted and if you had hugeTLB support enabled.

At the pktgen-DPDK level directory we have the 'tools/setup.sh' script, which needs to be run as root once per boot. The script contains a commands to setup the environment.

Make sure you run the setup script as root via './tools/setup.sh'. The setup script is a bash script and tries to setup the system correctly, but you may have to change the script to match your number of huge pages you configured above and ports.

The modprobe uio command, in the setup script, loads the UIO support module into the kernel plus it loads the igb-uio.ko module into the kernel. The two echo commands, in the setup script, finish setting up the huge pages one for each socket. If you only have a single socket system then comment out the second echo command. The last command is to display the huge TLB setup.

Edit your .bashrc or .profile or .cshrc to add the environment variables. I am using bash: # vi ~/.bashrc Add the following lines: Change the $RTE_SDK to the location of the DPDK version directory. Your SDK directory maybe named differently, but should point to the DPDK SDK directory.

Make sure you have the Linux kernel headers installed as DPDK requires them to build the kernel modules. On Ubuntu I run the following:

# sudo apt-get install linux-headers-uname -r``

You will need to adjust the version number to match your current kernel version. If you upgrade your system or kernel version you will need to install the correct headers and rebuild the RTE_TARGET directory.

``

sudo apt-get install libpcap-dev

export RTE_SDK= export RTE_TARGET=x86_64-native-linuxapp-gcc or use clang if you have it installed export RTE_TARGET=x86_64-native-linuxapp-clang Create the DPDK build tree:

cd $RTE_SDK

make install T=x86_64-native-linuxapp-gcc -j

`` This above command will create the x86_64-native-linuxapp-gcc directory in the top level of the current-dkdp directory. The above command will build the basic DPDK libraries and build tree.

Next we build pktgen: ``

cd

make

You should now have pktgen built and to run pktgen type 'sudo -E ./tools/run.sh', which is a script to help with the command line options of pktgen. You may need to modify this script for your system and configuration.

cat ./tools/run.sh

The '--socket-mem 256,156' DPDK command will allocate 256M from each CPU (two in this case). Do not use the '-m NNN' and '--socket-mem NN,NN' commands on the same command line.

The pktgen program follows the same format as a standard DPDK linuxapp, meaning the first set of arguments '-l 0-4' are the standard DPDK arguments. This option defines the number of logical cores to be used by pktgen. The 1f states 5 lcores are used and the '3c' is just a bit array for each lcore to be used. The '-P' enables promiscuous mode on all ports if you need that support. The '-m "..."' sets up the port to lcore mapping for pktgen.

The second half of the command line followed by the '--' is pktgen specific options.

The pktgen requires 2 logical cores for a minimum system. The first lcore 0 used for pktgen command line and is used for timers also displaying the text on the screen and lcores 1-n are used to do the packet receive and transmits along with anything else related to packets. You do not need to start at lcore zero, but the first lcore in the bitmap from in the least signification bit location is the display and timer lcore used by pktgen.

The -m format now allows the developer to have different lcores for rx and tx instead of rx/tx on the same lcore. The above format of {1:3}.0 states to use lcore 1 for rx and lcore 3 for tx on port 0. Make sure you select different lcores for the rx and tx so that only a single rx or tx function is on a single physical core. If you pick the rx/tx functions on different lcores, but on the same physical core you will not be able to get the performance you want as the single physical core will be trying to do both Rx/Tx functions.

The '-n 2' is a required argument for DPDK and denotes the number of memory channels.

*** New setup and run python script with config files ***

Using the new tools/run.py script to setup and run pktgen with different configurations. The configuration files are located in the cfg directory with filenames ending in .cfg.

To use a configuration file; `` $ ./tools/run.py -s default # to setup the ports and attach them to DPDK (only needed once per boot)

$ ./tools/run.py default # Run the default configuration `` The configuration files are python scritps or a set of variables that run.py uses to initialize and run pktgen. Here is an example of the default.cfg file:

A command line passing in a pktgen/test/set_seq.pkt file to help initialize pktgen with some default values and configurations. You can also replace the filename using the '-f' command with a Lua script file ending in .lua instead of .pkt. BTW, if the filename ends in anything other then .lua it is treated as a .pkt file.

./app/pktgen -l 0-4 -n 3 --proc-type auto --socket-mem 128,128 -- -P -m "[1:3].0, [2:4].1" -f test/set_seq.pkt

-- test/set_seq.lua The Lua version is easier to remember the layout of the agruments if you want to use that one instead of set_seq.pkt file.

-- Two Pktgens running on the same machine with connected via a loopback ports

Look at the two new files pktgen-master.sh and pktgen-slave.sh for some help on the configuration to run two pktgens at the same time on the same machine.


-- Socket Support for Pktgen.

Pktgen has a TCP socket connection to allow you to control Pktgen from a remote program or console. The TCP connection is using port 0x5606 or 22022 and presents a Lua command shell interface. If you telnet to the machine running Pktgen on port 22022 you will get a lua command shell like interface. This interface does not have a command line prompt, but you can issue Lua code or load script files from the local disk of the machine. You can also send programs to the remote Pktgen machine to load scripts from a remote location.

One method to connect to Pktgen is using telnet, but another method would be to use 'socat' program on a Linux machine. The socat program is very powerfull application and can do a lot of things. I used socat to debug Pktgen using the following command, which gives me a readline inteface to Pktgen's socket interface.

$ socat -d -d READLINE TCP4:localhost:22022

'You will see socat create the connection and then wait for Lua command scripts for you' To exit this command type Control-D to exit and close the connection.

You can also just send Pktgen a script file and display the ouptut.


$ socat - TCP4:localhost:22022 < test/hello-world.lua

Lua Vesrion: Lua 5.2 Pktgen Version : 2.9.x Pktgen Copyright : Copyright (c) <2010-2016>, Intel Corporation Pktgen Authors : Keith Wiles @ Intel Corporation

Hello World!!!!

Here is the program I sent Pktgen:

$ cat test/hello-world.lua package.path = package.path ..";?.lua;test/?.lua;app/?.lua;"

printf("Lua Vesrion: %s\n", pktgen.info.Lua_Version); printf("Pktgen Version : %s\n", pktgen.info.Pktgen_Version); printf("Pktgen Copyright : %s\n", pktgen.info.Pktgen_Copyright); printf("Pktgen Authors : %s\n", pktgen.info.Pktgen_Authors);

printf("\nHello World!!!!\n");

Here is a command from my Mac Book pro laptop, which loads a file from the local disk where Pktgen is running and then we execute the file with 'f()'.


$ socat READLINE TCP4:172.25.40.163:22022 f,e = loadfile("test/hello-world.lua") f() Lua Version: Lua 5.2 Pktgen Version : 2.9.x Pktgen Copyright : Copyright (c) <2010-2016>, Intel Corporation Pktgen Authors : Keith Wiles @ Intel Corporation

Hello World!!!!

You can also just send it commands via echo.


$ echo "f,e = loadfile('test/hello-world.lua'); f();"| socat - TCP4:172.25.40.163:22022 Lua Version: Lua 5.2 Pktgen Version : 2.9.x Pktgen Copyright : Copyright (c) <2010-2016>, Intel Corporation Pktgen Authors : Keith Wiles @ Intel Corporation
