Adding\n run-time selection ability means this can be used from distro packages\n and/or DPDK can be compiled on an older CPU and run on a newer CPU.\n2) Adds an optimized CRC implementation based on the AVX512 and\n VPCLMULQDQ instruction sets.\n \nFor further details, please see the commit messages of the individual\npatches.\n\nv4:\n* Fixed build issue when older version of meson is used (0.47.1)\n* Addressed review comments\n * remove Intel copyright header from neon CRC file\n * tidy-up of register initialisation\n\nv3:\n* Re-submitted v2 as encountered problems when originally submitting it.\n\nv2:\n* Added support for run-time selection of optimal architecture-specific\n CRC, based on v1 review comment.\n* Added full working AVX512/VPCLMULQDQ support for CRC32-Ethernet and\n CRC16-CCITT.\n\nv1:\n* Initial version, with incomplete AVX512/VPCLMULQDQ support for\n CRC32-Ethernet only.\n\nMairtin o Loingsigh (2):\n net: add run-time architecture specific CRC selection\n net: add support for AVX512/VPCLMULQDQ based CRC\n\n app/test/test_crc.c | 11 +-\n config/x86/meson.build | 6 +-\n doc/guides/rel_notes/release_20_11.rst | 6 +\n lib/librte_net/meson.build | 89 ++++-\n lib/librte_net/net_crc.h | 45 +++\n lib/librte_net/net_crc_avx512.c | 423 ++++++++++++++++++++++\n lib/librte_net/{net_crc_neon.h => net_crc_neon.c} | 26 +-\n lib/librte_net/{net_crc_sse.h => net_crc_sse.c} | 34 +-\n lib/librte_net/rte_net_crc.c | 100 +++--\n lib/librte_net/rte_net_crc.h | 4 +-\n 10 files changed, 672 insertions(+), 72 deletions(-)\n create mode 100644 lib/librte_net/net_crc.h\n create mode 100644 lib/librte_net/net_crc_avx512.c\n rename lib/librte_net/{net_crc_neon.h => net_crc_neon.c} (95%)\n rename lib/librte_net/{net_crc_sse.h => net_crc_sse.c} (94%)" }
