This repository puts together all the necessary pieces to generate Limago.
Make sure you are using Vivado 2018.3 IP Build 2404404. It seems to be a bug in Vivado 2018.3.1 IP Build 2486929 that produces combinational loops in the synthesized HLS.
Before generating any project check each submodule's README.md to verify that everything is set properly
So far VCU118 and Alveo U200 are supported.
In order to support Alveo U280 you must change the part for the HLS designs, run
cd submodules/fpga-network-stack-core/scripts; sed -i 's/xcvu9p-flga2104-2l-e/xcu280-fsvh2892-2L-e/g' $(ls); cd -
In order to clone this repository you need git lfs installed.
This repository uses submodules and git lfs, check Installing Git Large File Storage to install it.
git clone git@github.com:hpcn-uam/Limago.git --recursive
The process is fully automated.
1.The first part consist on generating the necessary IP-Cores
make ips
a. Check available projects
make help
b. Create Project
make create_prj_vcu118-fns-single-toe-iperf
Once the project is create you can open it. The projects are created under the folder projects/<project_name>
For instance, you can open the project with Vivado:
vivado projects/vcu118-fns-single-toe-iperf/vcu118-fns-single-toe-iperf.xpr
You can either launch it manually from the GUI or using the following command:
make implement_prj_vcu118-fns-single-toe-iperf
It is suggested to close the GUI when launching this command.
Once the FPGA has been programmed you can check if the link is up using the VIO (vio_cmac_synq_0) within Interfaces hierarchy , the signal cmac_sync_0_cmac_aligned_sync must value '1'.
If the board is attached through PCIe, the link can be checked using the cmac_stats program within the Software folder. In order to perform this, after programming the FPGA a host reboot is mandatory so as to enumerate the PCIe devices to detect the XDMA (PCIe rescan has not been tested). Check README.md to download and install the driver. Execute cmac_stats and you will get the stats of the CMAC and the Tx and Rx status.
By default Limago IP address is 192.168.0.5, network mask 255.255.255.0 and its MAC address is 00:0a:35:02:9d:e5
Once you have configured your HOST with a proper IP address in the same subnetwork as Limago you can use arping and ping to reach Limago.
arping -I <interface_name> 192.168.0.5
ping 192.168.0.5
This section describes how to test the echo application, valid for the project(s): vcu118-fns-single-toe-echo
In this case the Limago only echoes the payload of the connection to the port 15000, therefore you can use telnet or ncat to test it.
This section describes how to test the iperf (version 2) application, valid for the project(s): vcu118-fns-single-toe-iperf and alveou200-fns-single-toe-iperf
In this case, the FPGA can work both as a client and as a server. Make sure that you have installed iperf (version 2) in the server machine.
iperf -c 192.168.0.5 -t 10 -i 1 -p 5011 --mss 1408 -e
First of all, the server machine must run iperf (version 2) a as server iperf -s -i 1. After that, you you can run the iperf application from the FPGA as a client.
sudo ./bin/hw_iperf2 -c <server_ip_address> -t 10 -p 5001 -e
