Subject: [PATCH v7 0/4] support protocol based buffer split
Date: Sun,  2 Oct 2022 05:05:17 +0800	[thread overview]
Message-ID: <20221001210521.15955-1-yuanx.wang@intel.com> (raw)
In-Reply-To: <20220812181552.2908067-1-yuanx.wang@intel.com>

Protocol type based buffer split consists of splitting a received packet
into several separate segments 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.

This patchset aims to support protocol header 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 different mempools.

Change log:
v7:
ice: Fix CI issue.

v6:
ice: Fix proto_hdr mappings to NIC configuration.

v5:
Define proto_hdr to use mask instead of single protocol type.
Define PMD to return protocol header mask.
Refine the doc and commit log.
Remove deprecated RTE_FUNC_PTR_OR_ERR_RET.

v4:
Change proto_hdr to a bit mask of RTE_PTYPE_*.
Add the description on how to put the unsplit packages.
Use proto_hdr to determine whether to use protocol based split.

v3:
Fix mail thread.

v2:
Add mbuf dump to the driver's buffer split path.
Add buffer split to the driver feature list.
Remove unsupported header protocols from the driver.

Yuan Wang (4):
  ethdev: introduce protocol header API
  ethdev: introduce protocol hdr based buffer split
  app/testpmd: add rxhdrs commands and parameters
  net/ice: support buffer split in Rx path
