Transparent eBPF Offload: Playing Nice with the Linux Kernel

By Nic Viljoen and Jakub Kicinski, Netronome

Netronome is developing transparent kernel acceleration based on XDP and eBPF. This allows bytecode intended for kernel applications to be directly offloaded using the upstreamed nfp_bpf_jit. The talk will focus on the basics of getting an XDP environment up and running, a couple of use cases and a simple demo of Netronome’s eBPF offload in action.

Transparent HW Acceleration Using eBPF

By Nic Viljoen, Netronome

To enable SmartNICs to be used in a way that is transparent in an in-tree hyperscale environment requires the reuse of programmable infrastructure within the kernel, the most suitable candidate is eBPF. This talk will explain how this offload is achieved, the next steps in development and show a very basic demo of the offload in acton.

P4, eBPF and Linux TC offload

By Dinan Gunawardena, Netronome

In this talk we discuss the mechanisms of utilizing the eBPF language to perform hardware accelerated network packet manipulation and filtering. P4 programs can be compiled into eBPF scripts for offload in the Linux kernel using the Traffic Classifier (TC) subsystem. We demonstrate how, using eBPF as an intermediate language, it has been possible to extend the TC to either Just In Time (JIT) compile eBPF code to x86 assembler for software offload or to IXP byte code for execution in a trusted hardware environment within the Netronome Agilio intelligent server adapter. We finish by encouraging the audience to experiment with their own eBPF applications within the TC hardware accelerated system. The TC kernel patches are available on the Linux Kernel Networking mailing list as a Request For Comment (RFC) contribution.
