- This patch set has the changes required for optimised hash library usage in
arm64 perspective
- Tested on Juno and Thunderx boards
- Tested and verified the changes with following DPDK unit test cases
hash_functions_autotest
hash_autotest
hash_perf_autotest
hash_scaling_autotes
- Created the new xgene1 machine target to address the difference
in optional armv8-a CRC extension availability compared to
default armv8-a machine target(enabled CRC extension by default)
- Supersededs the [dpdk-dev] [PATCH] hash: replace libc memcmp with
optimized memory compare functions for arm64 patch
Jerin Jacob (4):
hash: replace libc memcmp with optimized memory compare functions for
arm64
hash: implement rte_hash_crc_* based on armv8-a CRC32 instructions
hash: select hash function as CRC if armv8-a CRC extension available
mk: add xgene1 machine target based on armv8-a
