##odp4vpp:

odp4vpp project aims to provide VPP with an additional vnet device based on OpenDataPlane (ODP is similar yet different from DPDK), with provisions for hardwareacceleration of packet paths. It envisions three deployment scenarios:

-Server + NICs -Systems on a Chip -SmartNIC with low to very high core count

The source code add support to build VPP with either odp-linux or odp-dpdk.

1. Build vpp with odp-linux:

Build the odp linux package by compiling odp from odp git repository:

git clone https://git.linaro.org/lng/odp.git

Follow the README steps for complete build.

cd odp ./bootstrap ./configure --prefix= make install

Set the environment variables with ODP config:

export PLATFORM=odp export ODP_INST_PATH=

Build vpp:

Follow the README steps for complete build.

cd vpp make install-dep make build make run

2. Build vpp with odp-dpdk:

Build the odp-dpdk package by compiling odp-dpdk from odp-dpdk git repository:

git clone https://git.linaro.org/lng/odp-dpdk.git

Follow the README.DPDK steps for complete build with dpdk.

cd odp-dpdk ./bootstrap ./configure --prefix= --with-sdk-install-path=/x86_64-native-linuxapp-gcc make install

Set the environment variables with ODP config:

export PLATFORM=odp export ODP_INST_PATH=

Note : Also check and copy dpdk/odp-dpdk libraries to default /usr/lib path for linking with vpp.

Build vpp:

Follow the README steps for complete build.

cd vpp make install-dep make build make run

Below is a basic verification test.

Note :For odp-dpdk the port has to bound with dpdk driver prior to test and interface name is passed as 0,1..etc.

1)Configure odp packet interface with mode ie (0-burst,1-queue,2-schedule) default mode is 0.

-create pktio-interface name hw-addr mode <0/1/2> -set int ip address odp- X.X.X.X/24 -set int state odp- up

2)Check the interface state: -sh int

3)Ping the configured interface from host machine and check the ARP and ipv4 FIB table: -sh ip arp -sh ip fib

4)Check the interface counters: -sh int

5)Check the statistics: -show run

6)Packet trace can be enabled using : -trace add odp-packet-input 10 -show trace

7)Delete the interface: -delete pktio-interface name

Below is example config logs:
