Subject: [dpdk-dev] [PATCH v3 0/2] net: add CRC run-time checks and AVX512/VPCLMULQDQ based CRC
Date: Tue, 29 Sep 2020 16:35:59 +0100 [thread overview]
Message-ID: <1601393761-11588-1-git-send-email-mairtin.oloingsigh@intel.com> (raw)
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.
v2:
* Added support for run-time selection of optimal architecture-specific
CRC, based on v1 review comment.
* Added full working AVX512/VPCLMULDQD support for CRC32-Ethernet and
CRC16-CCITT.
v1:
* Initial version, with incomplete AVX512/VPCLMULDQD support for
CRC32-Ethernet only.
