AQUANTIA AVTP Pipeline Contribution Notes

General Status

AVTP Pipeline from https://github.com/AVnu/OpenAvnu/tree/master/lib/avtp_pipeline adapted for Aquantia’s AQC107/AQC113 Network Interface Card.

Integrated with OpenAvnu:

• gPTP
• MAAP
• MSRP
• Build system

Building Current OpenAvnu

Ubuntu 18.04LTS

Install dependencies

$ sudo apt update
$ sudo apt install build-essential cmake
$ sudo apt install linux-headers-generic libglib2.0-dev
$ sudo apt install libpcap-dev libpci-dev libsndfile1-dev libjack-dev
$ sudo apt install libasound2-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

Git Submodules

After checking out the OpenAvnu git repository submodules should be configured by going: git submodule init
git submodule update

Building everything Building from the repo root
$ make all

Binaries will be installed in lib/avtp_pipeline/build/bin. Build files will be in the lib/avtp_pipeline/build_avdecc directory, to avoid interfering with the AVTP Pipeline build files.

The openavb_avdecc binary needs to be run in addition to the AVTP pipeline binary (openavb_harness or openavb_host) for AVDECC to be supported.

Running OpenAvnu daemons

Helper scripts in the repo root.
$ sudo ./run_atl.sh eth1
Load the atl driver
$ sudo ./run_daemons.sh eth1
Start the gptp, msrp, maap, and shaper daemons. Supply the interface name (ethx) as parameter.
Daemons can also be started individually using the run_gptp.sh, run_srp.sh, run_maap.sh, and run_shaper.sh
$ sudo ./stop_daemons.sh
Stop the gptp, msrp, maap, and shaper daemons. Don’t use this command while AVTP Pipeline is running.

Running the OpenAvnu AVTP Pipeline example

$sudo ./run_avtp_pipeline.sh eth1
Run the current OpenAvnu AVTP Pipeline example. Supply the interface name (eth1) as parameter
$sudo ./stop_avtp_pipeline.sh eth1
Stop the current OpenAvnu AVTP Pipeline example. The script will also attempt to cleanly recover if the AVTP pipeline binaries crashed.
