Subject: [dpdk-dev] [PATCH 0/3] regex/mlx5: support scattered mbuf
Date: Wed, 10 Mar 2021 01:57:29 +0200
Message-ID: <20210309235732.3952418-1-suanmingm@nvidia.com> (raw)

The scattered mbuf was not supported in mlx5 RegEx driver. This patch
set adds the support of scattered mbuf by UMR WQE.

UMR WQE can convert multiple mkey's memory sapce to contiguous space.
Take advantage of the UMR WQE, scattered mbuf in one operation can be
converted to an indirect mkey. The RegEx which only accepts one mkey
can now process the whole scattered mbuf.

The maximum scattered mbuf can be supported in one UMR WQE is now
defined as 64. Multiple operations scattered mbufs can be add to one
UMR WQE if there is enough space in the KLM array, since the operations
can address their own mbuf's content by the mkey's address and length.
However, one operation's scattered mbuf's can't be placed in two
different UMR WQE's KLM array, if the UMR WQE's KLM does not has enough
free space for one operation, a new UMR WQE will be required.

In case the UMR WQE's indirect mkey will be over wrapped by the SQ's
WQE move, the meky's index used by the UMR WQE should be the index of
last the RegEX WQE in the operations. As one operation consumes one
WQE set, build the RegEx WQE by reverse helps address the mkey more
efficiently. Once the operations in one burst consumes multiple mkeys,
when the mkey KLM array is full, the reverse WQE set index will always
be the last of the new mkey's for the new UMR WQE.

In GGA mode, the SQ WQE's memory layout becomes UMR/NOP and RegEx WQE by
interleave. The UMR and RegEx WQE can be called as WQE set. The SQ's pi
and ci will also be increased as WQE set not as WQE.

For operations don't have scattered mbuf, uses the mbuf's mkey directly,
the WQE set combination is NOP + RegEx.
For operations have scattered mubf but share the UMR WQE with others,
the WQE set combination is NOP + RegEx.
For operations complete the UMR WQE, the WQE set combination is UMR +
RegEx.
