DPDK - PCIe Steering Tags Meeting on 10/23/24

DPDK - PCIe Steering Tags Meeting on 10/23/24

[Wathsala Wathawana Vithanage]

Hi all,
 
This is an invitation to discuss adding PCIe steering tags support to DPDK.
We have had brief conversations over the idea at the DPDK summit.
Steering tags allows stashing of descriptors and packet data closer to the CPUs, possibly allowing for lower latency and higher throughput. 
This feature requires contributions from CPU vendors and NIC vendors. 
The goal of the meeting is to present the next version of the API and seek support for implementation from other participants in the community. 

I will be sending out the RFC some time this week, so there will be a plenty of time before the meeting to go over it.

Agenda:
- Brief introduction to the feature
- Introduce the APIs from RFC v2 (this will be submitted to the community before the call)
- Dependencies on kernel support - API for reading steering tags
- Addressing ABI in advance as patches will not be ready by 24.11

Please join the call if you are interested in the topic.

Thanks.
