Many modern NICs have built-in packet processing capabilities that can
effectively perform the type of use case that XDP is often used for.
Stephan Diestelhorst, Neil Turton, Kieran Mansley, Kimon Karras, Rip
Sohan , Thomas Calvert  and Steven Pope say that being able to
seamlessly offload this XDP code to the NIC – under the control of the
Linux networking subsystem and tooling – would increase server
efficiency and performance without affecting the user experience.

Stephan Diestelhorst et al will discuss Nanotube: an open-source
compiler that consumes standard XDP code and produces a tailor-made,
application-specific dataflow pipeline suitable for execution on FPGA
NIC platforms. They have demonstrated generated Katran on AMD/Xilinx
FPGA-based NICs to offload with throughput at line rate (100 Gbps) on
AMD NICs!

In this talk they will describe (i) the structure of the compiler;
(ii) performance of typical workloads; and (iii) how map accesses by
host software are supported using specially annotated packets over the
normal host data path. And last but not least they will discuss
requirements to allow better integration and support by the Linux
kernel, in particular the validator, map handling, and vendor-neutral
support requirements.

cheers,
jamal
