Subject: [PATCH 0/2] rewritten rte_hash_crc() call
Date: Wed, 3 Sep 2014 12:05:49 +0600 [thread overview]
Message-ID: <1409724351-23786-1-git-send-email-e_zhumabekov@sts.kz> (raw)
As SSE4.2 provides CRC32 instructions with either 32 and 64 bit operands,
new rte_hash_crc_8byte() call assisted with _mm_crc32_u64 intrinsic may be
useful.
Then, rte_hash_crc() function is redesigned to take advantage of both 32
and 64 bit operands. This improves the function's performance significantly.
Results of my test run on a single CPU core are below.

hash: add new rte_hash_crc_8byte call
