General informations

The Linux kernel configuration item CONFIG_CRYPTO_CRC32_PCLMUL:

Help text

From Intel Westmere and AMD Bulldozer processor with SSE4.2 and PCLMULQDQ supported, the processor will support CRC32 PCLMULQDQ implementation using hardware accelerated PCLMULQDQ instruction. This option will create 'crc32-plcmul' module, which will enable any routine to use the CRC-32-IEEE 802.3 checksum and gain better performance as compared with the table implementation.
