Subject: [dpdk-dev] RFC: Enahancements to Rx adapter for DPDK 21.11
Hi dpdk-dev,
We would like to submit series of patches to Rx adapters that will enhance the configuration and performance.
Please find the details below.
(1) Configure Rx event buffer at run time
Add new api to configure the size of the Rx event buffer at run time.
This api allows setting the size of the event buffer at adapter level.
(2) Change packet enqueue buffer in Rx adapter to circular buffer
Rx adapter uses memmove() to move unprocessed events to the begining
of packet enqueue buffer which consumes good amount of CPU cycles.
(3) Add API to retrieve the Rx queue info
Rx queue info containining flags for handling received packets,
event queue identifier, schedular type, event priority,
polling frequence of the receive queue and flow identifier
(4) Add adapter_stats cli to retrive Rx/Tx adapter stats and rxq info
This cli displays Rx and Tx adapter stats containing recieved packet count,
eventdev enqueue count, enqueue retry count, event buffer size, queue poll count,
transmitted packet count, packet dropped count, transmit fail count etc and rx queue info.
(5) Update Rx timestamp in mbuf using mbuf dynamic field
Add support to register timestamp dynamic field in mbuf
Update the timestamp in mbuf for each packet before eventdev enqueue
We look forward to feedback on this proposal. Once we have initial feedback, patches will be submitted for review.
Thanks,
Ganapati
