Ubuntu 16.04 & Amazon Linux 2 install DPDK

Ubuntu 16.04

Ubuntu is VMware workstation virtual machine. 4G memory, 2 Cores.

Please add one or more network adapter for the virtual.

Open the virtual machine file(xxx.vmx), then replace this line for each interface(DPDK interface):

ethernet1.virtualDev = "e1000" -> ethernet1.virtualDev = "vmxnet3"

Because vmxnet3 supports Multiqueue and DPDK [1]
Run this command, if the output like this, that means interface support Multiqueue:

  root@sdn:/home/sdn# cat /proc/interrupts  | grep ens160
  56:         29        139   PCI-MSI 1572864-edge      ens160-rxtx-0
  57:         14         13   PCI-MSI 1572865-edge      ens160-rxtx-1
  58:          0          0   PCI-MSI 1572866-edge      ens160-event-2

Then shutdown the DPDK interface to allow DPDK to use them.

ifconfig ens160 down

Download DPDK from http://core.dpdk.org/download/

wget http://fast.dpdk.org/rel/dpdk-19.08.2.tar.xz
tar -xvf dpdk-19.08.2.tar.xz

Setup environment variable for DPDK

root@sdn:/home/sdn# cd dpdk-stable-19.08.2/
export RTE_SDK=/home/sdn/dpdk-stable-19.08.2/
export RTE_TARGET=x86_64-native-linux-gcc

Update OS and install library

apt update
apt install  libnuma-dev -y

Add UIO modules

modprobe uio

Enter the DPDK directory and run dpdk-setup.sh script

./usertools/dpdk-setup.sh

Do these things during the setup.

• Set hugepages(For example 512)
• Build the DPDK environment(For example x86_64-native-linux-gcc)
• Insert IGB UIO module
• Bind the interface with DPDK(make sure you already shutdown them before do it)

Run helloworld for test

cd /examples/helloworld
make
./build/helloworld

You should be able to see this kind of output.

****
hello from core 1
hello from core 0

Now DPDK has been installed to the Ubuntu.

Amazon Linux 2

For Amazon EC2, you need use Nitro-based instance because it supports ENA driver. DPDK support ENA. Just add one or more interface to the EC2 and shutdown them.
Other procedures remains the same.
