Subject: [dpdk-dev] [PATCH v3 0/4] add new k32v64 hash table
Date: Wed, 15 Apr 2020 19:17:23 +0100	[thread overview]
Message-ID: <cover.1586974408.git.vladimir.medvedkin@intel.com> (raw)
In-Reply-To: <cover.1586369591.git.vladimir.medvedkin@intel.com>

Currently DPDK has a special implementation of a hash table for
4 byte keys which is called FBK hash. Unfortunately its main drawback
is that it only supports 2 byte values.
The new implementation called K32V64 hash
supports 4 byte keys and 8 byte associated values,
which is enough to store a pointer.

It would also be nice to get feedback on whether to leave the old FBK
and new k32v64 implementations or deprecate the old one?

v3:
- added bulk lookup
- avx512 key comparizon is removed from .h

v2:
- renamed from rte_dwk to rte_k32v64 as was suggested
- reworked lookup function, added inlined subroutines
- added avx512 key comparizon routine
- added documentation
- added statistic counters for total entries and extended entries(linked list)

Vladimir Medvedkin (4):
  hash: add k32v64 hash library
  hash: add documentation for k32v64 hash library
  test: add k32v64 hash autotests
  test: add k32v64 perf tests
