This repository contains eBPF XDP demo applications.
Most demos can be run on XDP compatible drivers or hardware. Each subdirectory provides instructions for loading the programs in “driver” and/or in “offload” mode. “Driver mode” loads the XDP program into the kernel where the processing is carried out by the host CPU, whilst “offloaded XDP” allows for the program to be run on hardware, such as with the Netronome Agilio® CX SmartNIC.
To enable XDP offload on a Agilio CX, please refer to Netronome eBPF user guides.
The sources for each demo are located in a specific subdirectory.
| Application | Kernel Required |
|---|---|
| Layer 4 Load Balancer | 4.17 |
| Programmable RSS | 4.18 |
| xdpdump | 4.18 |
The tools directory does not actually contain tools for end users, but
gathers various libraries and kernel files coming from the kernel tree and
required for compiling the samples.
- These applications are prototypes and are not suitable for production use.
