18. ICE PF Enable Buffer Split¶
18.1. Description¶
Protocol based buffer split consists of splitting a received packet into two separate regions based on the packet content. It is useful in some scenarios, such as GPU acceleration. The splitting will help to enable true zero copy and hence improve the performance significantly.
It supports protocol split based on current buffer split. When Rx queue is configured with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT offload and corresponding protocol, packets received will be directly split into two different mempools with expected hdr and payload length/content.
For validation, we will focus on: 1. Configuration of protocol based buffer split is applied. Setup buffer split: Per port: testpmd>port config 0 rx_offload buffer_split on Per queue: testpmd>port 0 rxq 0 rx_offload buffer_split on
Set the protocol type of buffer split: testpmd>set rxhdrs (eth|ipv4|ipv6|ipv4-tcp|ipv6-tcp|ipv4-udp|ipv6-udp| ipv4-sctp|ipv6-sctp|grenat|inner-eth|inner-ipv4|inner-ipv6| inner-ipv4-tcp|inner-ipv6-tcp|inner-ipv4-udp|inner-ipv6-udp| inner-ipv4-sctp|inner-ipv6-sctp)
2. Packets received in ice scalar path(–force-max-simd-bitwidth=64) can be devided into two mempools with expected hdr and payload length/content specified by protocol type.
Note
Currently, it supports 6 kinds segmentation of buffer split: * Outer mac: set rxhdrs eth * Inner mac: set rxhdrs inner-eth * Inner l3: set rxhdrs ipv4|ipv6|inner-ipv4|inner-ipv6 * Inner l4: set rxhdrs ipv4-udp|ipv4-tcp|ipv6-udp|ipv6-tcp|inner-ipv4-udp|inner-ipv4-tcp|inner-ipv6-udp|inner-ipv6-tcp * Inner sctp: set rxhdrs ipv4-sctp|ipv6-sctp|inner-ipv4-sctp|inner-ipv6-sctp * Tunnel: set rxhdrs grenat
