Help text

CRC16 CRC algorithm used for the T10 (SCSI) Data Integrity Field (DIF)

Architecture: x86_64 using: - PCLMULQDQ (carry-less multiplication)

CRCT10DIF PCLMULQDQ hardware acceleration found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_CRCT10DIF_PCLMUL:

• prompt: CRCT10DIF PCLMULQDQ hardware acceleration
• type: tristate
• depends on: CONFIG_X86 && CONFIG_64BIT && CONFIG_CRC_T10DIF
• defined in crypto/Kconfig
• found in Linux kernels: 3.12–3.19, 4.0–4.20, 5.0–5.19, 6.0, 6.0+HEAD
• modules built: crct10dif-pclmul, crct10dif-pclmul

Help text

For x86_64 processors with SSE4.2 and PCLMULQDQ supported, CRC T10 DIF PCLMULQDQ computation can be hardware accelerated PCLMULQDQ instruction. This option will create 'crct10dif-pclmul' module, which is faster when computing the crct10dif checksum as compared with the generic table implementation.
