PKTGEN-DPDK Introduction

PKTGEN-DPDK is a 6wind outsourcing tool developed by Intel DPDK, which is used to test the packet forwarding capability of DPDK;

You can see its details in Https://github.com/Pktgen/Pktgen-DPDK;

My test environment is REHL6.2 system;

Download Source mode

Git  clone  http://github.com/Pktgen/Pktgen-DPDK.git

installation compiled source code;

Download the source code after entering the PKTGEN-DPDK/DPDK directory, the implementation of installation;

Make install T=X86_64-WR-LINUXAPP-GCC

If you encounter the following variable name duplicate definition error;

In file included from/home/linzh/repo/pktgen-dpdk/dpdk/lib/libwr_mcos/rte_mcos.c:81:
/home/linzh/repo/ Pktgen-dpdk/dpdk/lib/libwr_mcos/rte_mcos.h:321:error:redefinition of the typedef ' mcos_master_t '

/home/ linzh/repo/pktgen-dpdk/dpdk/lib/libwr_mcos/rte_mcos_debug.h:113:note:previous declaration of ' mInfo_t ' is here

Need to modify the file variable definition, I just temporarily made a change;

Vim/home/linzh/repo/pktgen-dpdk/dpdk/lib/libwr_mcos/rte_mcos_debug.h

%s/minfo_t/minfo_t_bak/g
%s/mcos_master_t/mcos_master_t_bak/g

Renaming the minfo_t in the Rte_mcos_debug.h file to Minfo_t_bak, renaming mcos_master_t to Mcos_master_t_bak;

setting environment variables;

Export rte_sdk= ' pwd '

export RTE_TARGET=X86_64-WR-LINUXAPP-GCC

Execute the script to install the configuration;

./tools/setup.sh

Run the scripts after running them separately

[6] Insert IGB UIO module
[7] Insert KNI module
[8] Setup hugepage mappings for Non-numa Systems

Install the new Intel NIC driver;

Set Hugepage information, I entered 1024, that is, allocating 1024 2M of memory, equal to 2G of memory space;

Run 11, take a DPDK test; in 11 if a core source, if the input F knock enter, that is, 0 to 3 of these core to test;

[One] Run TESTPMD application in interactive mode ($RTE _TARGET/APP/TESTPMD)

Option:11


  Enter hex bitmask of cores to execute TESTPMD app
  in example:to execute app on cores 0 to 7, Enter 0xf F
bitmask:f

Enter F after knocking in the carriage

Show some of the information below to indicate success

Then try running the start and stop commands separately;

Test Pktgen below

Enter Pktgen-dpdk/dpdk/wr-examples/pktgen catalogue;

Execute make to compile Pktgen;

Run the setup script to configure the environment, the script is actually configured Hugepage, and the new installation of the Intel network card driver;

./setup

Run doit to test pktgen;

./doit

If an error is found;

This should be the execution procedure is, the incoming test parameter error;

--socket-mem 128,128

There is a problem with this parameter, I do not have a solution for the moment, do not understand the specific use of this parameter, the following 128 removed and then run;

./app/build/pktgen-c e-n 3--proc-type Auto--SOCKET-MEM 128--file-prefix PG---p 0x14-p-M "2.0, 3.1"-F Test/set_se Q.cmd

-C refers to the selection of the core mask, E equals 1110 is the choice of 1, 2, 3rd core;

--proc-type selected Auto, if it is the current system first executed DPDK related program, select Primary mode, if the second is secondary mode;

--file-prefix PG Sets the filename prefix of the/mnt/huge/memory allocation module;

-P 0x14 0x14 equals 00010100, select one of the 2 Intel related network card ports in your current system;

-P enables network blending mode,

-M "2.0, 3.1" This refers to a matrix model, 2.0 refers to the 2nd Lcore bound Port 0, 3.1 refers to the lcore3 bound Port 1

-F Test/set_seq.cmd Finally imports the Pktgen execution configuration file and, when executing Pktgen, uses the configuration to generate the packet;

The

eventually appears with the following interface; You can have more official Readme.pktgen files, perform some configuration, and related tests;
