Subject: [dpdk-dev] [PATCH 0/3] add new Double Word Key hash table
Date: Mon, 16 Mar 2020 13:38:26 +0000 [thread overview]
Message-ID: <cover.1584360151.git.vladimir.medvedkin@intel.com> (raw)
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 DWK (double word key) hash
supports 8 byte 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 DWK implementations, or whether to deprecate the old one?
Vladimir Medvedkin (3):
hash: add dwk hash library
test: add dwk hash autotests
test: add dwk perf tests
