On PPC_8xx, CRC32_SLICEBY4 is more efficient (almost twice) than CRC32_SLICEBY8, as shown below: With CRC32_SLICEBY8: [ 1.109204] crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64 [ 1.114401] crc32: self tests passed, processed 225944 bytes in 15118910 nsec [ 1.130655] crc32c: CRC_LE_BITS = 64 [ 1.134235] crc32c: self tests passed, processed 225944 bytes in 4479879 nsec With CRC32_SLICEBY4: [ 1.097129] crc32: CRC_LE_BITS = 32, CRC_BE BITS = 32 [ 1.101878] crc32: self tests passed, processed 225944 bytes in 8616242 nsec [ 1.116298] crc32c: CRC_LE_BITS = 32 [ 1.119607] crc32c: self tests passed, processed 225944 bytes in 3289576 nsec Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>
