Subject: [dpdk-dev] [PATCH v2 0/5] optimized Toeplitz hash implementation
Date: Fri, 15 Oct 2021 10:30:01 +0100 [thread overview]
Message-ID: <1634290206-251913-1-git-send-email-vladimir.medvedkin@intel.com> (raw)
In-Reply-To: <1630944239-363648-1-git-send-email-vladimir.medvedkin@intel.com>
This patch series adds a new optimized implementation for the Toeplitz hash
function using Galois Fields New instruction (GFNI).
The main use case of this function is to calculate the hash value for a single
data, so there is no bulk implementation.
For performance reasons, the implementation was placed in a public header.
It is the responsibility of the user to ensure the platform supports GFNI
(by doing runtime checks of rte_thash_gfni_supported variable) before calling
these functions.
v2:
- fixed typos
- made big_rss_key static const and indented
- addressed Konstantin's comments
Vladimir Medvedkin (5):
hash: add new toeplitz hash implementation
hash: enable gfni thash implementation
doc/hash: update documentation for the thash library
test/thash: add tests for a new Toeplitz hash function
test/thash: add performance tests for the Toeplitz hash
