wei xiao b0ae5ae2ad crc32c: optimize aarch64 crc32c implementation ... ARMv8 defines PMULL crypto instruction. This patch optimizes crc32c calculate with the instruction when available rather than original linear crc instructions. ceph crc32c performance unit test shows that the optimization get ~ x3.90 speedups on ThunderX ARM Core@2.0GHz (Cavium) ~ x1.45 speedups on ARM Cortex-A57@2.1GHz (Huaiwei) ~ x1.16 speedups on ARM Cortex-A57@2.0GHz (Softiron) Jira: ENTLLT-358 Change-Id: I657422cd20c9ca78237cd060210a5383f4122575 Signed-off-by: wei xiao <wei.xiao@linaro.org>		2017-02-04 06:20:50 +00:00
