Subject: [dpdk-dev] [PATCH v4 0/2] net: add CRC run-time checks and AVX512/VPCLMULQDQ based CRC
Date: Tue,  6 Oct 2020 17:23:17 +0100
Message-ID: <20201006162319.7981-1-mairtin.oloingsigh@intel.com> (raw)
In-Reply-To: <1601393761-11588-1-git-send-email-mairtin.oloingsigh@intel.com>

This patchset makes two significant enhancements to the CRC modules of
the rte_net library:

1) Adds run-time selection of the optimal architecture-specific CRC path.
   Previously the selection was solely made at compile-time, meaning it
   could only be built and run on the same generation of CPU. Adding
   run-time selection ability means this can be used from distro packages
   and/or DPDK can be compiled on an older CPU and run on a newer CPU.
2) Adds an optimized CRC implementation based on the AVX512 and
   VPCLMULQDQ instruction sets.
   
For further details, please see the commit messages of the individual
patches.

v4:
* Fixed build issue when older version of meson is used (0.47.1)
* Addressed review comments
  * remove Intel copyright header from neon CRC file
  * tidy-up of register initialisation

v3:
* Re-submitted v2 as encountered problems when originally submitting it.

v2:
* Added support for run-time selection of optimal architecture-specific
  CRC, based on v1 review comment.
* Added full working AVX512/VPCLMULQDQ support for CRC32-Ethernet and
  CRC16-CCITT.

v1:
* Initial version, with incomplete AVX512/VPCLMULQDQ support for
  CRC32-Ethernet only.
