Our friends at Intel and AMD will share their thoughts on how to integrate P4TC[1] into their drivers.

In this talk Anjali Singhai, Neha Singh, James Choi, Namrata Limaye, Sridhar Samudrala, Mahesh Shirshyad and Vipin Jain will discuss enhancements to existing TC offload interfaces to accommodate multiple P4 pipeline and runtime control. They will elaborate on the association of the s/w and h/w datapaths, hardware P4 dataplane loading and initialization as well as runtime control (using the classical skip_sw/hw flagging). These details will include describing the kernel infrastructures and any extension to current TC offload. Anjali et all will discuss potential enable shimming of legacy kernel offloads such as tc-flower on to P4TC interfaces. Additionally, they will talk about interfaces to support legacy hooks (switchdev ops, FDB ops) and coexistence of these with P4TC compatible driver. They will make the infrastructure code at the conference.

cheers, jamal
