[PATCH v3 0/4] Patchset to use PCLMULQDQ to accelerate CRC-T10DIF checksum computation

2013-05-01 Thread Tim Chen
Currently the CRC-T10DIF checksum is computed using a generic table lookup algorithm. By switching the checksum to PCLMULQDQ based computation, we can speedup the computation by 8x for checksumming 512 bytes and even more for larger buffer size. This will improve performance of SCSI drivers turni
