Subject: [dpdk-dev] [PATCH v5 0/7] rte_hash_crc reworked to be platform-independent
Date: Thu, 20 Nov 2014 11:15:44 +0600	[thread overview]
Message-ID: <cover.1416459284.git.e_zhumabekov@sts.kz> (raw)
In-Reply-To: <1409724351-23786-1-git-send-email-e_zhumabekov@sts.kz>

These patches bring a fallback mechanism to ensure that CRC32 hash is calculated regardless of hardware support from CPU (i.e. SSE4.2 intrinsics).
Performance is also improved by slicing data in 8 bytes.

Patches were tested on machines either with and without SSE4.2 support.

Software implementation seems to be about 4-5 times slower than SSE4.2-enabled one. Of course, they return identical results.

Summary of changes:
* added CRC32 software implementation, which is used as a fallback in case SSE4.2 is not available, or if SSE4.2 is intentionally disabled.
* added rte_hash_crc_set_alg() function to control availability of SSE4.2.
* added rte_hash_crc_8byte() function to calculate CRC32 on 8-byte operand.
* reworked rte_hash_crc() function which leverages both versions of CRC32 hash calculation functions with 4 and 8-byte operands.
* removed compile-time checks from test_hash_perf and test_hash.
* setting default algorithm implementation as a constructor while application startup.
* SSE4.2 intrinsics are implemented through inline assembly code.
* added additional run-time check for 64-bit support.

Yerden Zhumabekov (7):
  hash: add software CRC32 implementation
  hash: add assembly implementation of CRC32 intrinsics
  hash: replace built-in functions implementing SSE4.2
  hash: add rte_hash_crc_8byte function
  hash: add fallback to software CRC32 implementation
  hash: rte_hash_crc() slices data into 8-byte pieces
  test: remove redundant compile checks
