CONFIG_CRYPTO_GHASH_ARM_CE: PMULL-accelerated GHASH using NEON/ARMv8 Crypto Extensions

General informations

The Linux kernel configuration item CONFIG_CRYPTO_GHASH_ARM_CE has multiple definitions:

PMULL-accelerated GHASH using ARMv8 Crypto Extensions found in arch/arm/crypto/Kconfig

The configuration item CONFIG_CRYPTO_GHASH_ARM_CE:

• prompt: PMULL-accelerated GHASH using ARMv8 Crypto Extensions
• type: tristate
• depends on: CONFIG_KERNEL_MODE_NEON
• defined in arch/arm/crypto/Kconfig
• found in Linux kernels: 4.1–4.13, 4.13+HEAD
• modules built: ghash-arm-ce

Help text

Use an implementation of GHASH (used by the GCM AEAD chaining mode) that uses the 64x64 to 128 bit polynomial multiplication (vmull.p64) that is part of the ARMv8 Crypto Extensions

Help text

Use an implementation of GHASH (used by the GCM AEAD chaining mode) that uses the 64x64 to 128 bit polynomial multiplication (vmull.p64) that is part of the ARMv8 Crypto Extensions, or a slower variant that uses the vmull.p8 instruction that is part of the basic NEON ISA.
