* crypto: arm64/crc32 - bring in line with generic CRC32Ard Biesheuvel2015-05-06
| | | | | | | | | The arm64 CRC32 (not CRC32c) implementation was not quite doing the same thing as the generic one. Fix that. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Steve Capper <steve.capper@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crc32 - Add ARM64 CRC32 hw accelerated moduleYazen Ghannam2014-11-20
This module registers a crc32 algorithm and a crc32c algorithm that use the optional CRC32 and CRC32C instructions in ARMv8. Tested on AMD Seattle. Improvement compared to crc32c-generic algorithm: TCRYPT CRC32C speed test shows ~450% speedup. Simple dd write tests to btrfs filesystem show ~30% speedup.
