CONFIG_CRYPTO_DEV_NX: Support for IBM PowerPC Nest (NX) cryptographic acceleration

General informations

The Linux kernel configuration item CONFIG_CRYPTO_DEV_NX has multiple definitions:

Support for IBM PowerPC Nest (NX) cryptographic acceleration found in drivers/crypto/Kconfig

The configuration item CONFIG_CRYPTO_DEV_NX:

• prompt: Support for IBM PowerPC Nest (NX) cryptographic acceleration
• type: bool
• depends on: CONFIG_PPC64
• defined in drivers/crypto/Kconfig
• found in Linux kernels: 4.2–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: nx-crypto

Help text

This enables support for the NX hardware cryptographic accelerator coprocessor that is in IBM PowerPC P7+ or later processors. This does not actually enable any drivers, it only allows you to select which acceleration type (encryption and/or compression) to enable.

Support for IBM Power7+ in-Nest cryptographic acceleration found in drivers/crypto/Kconfig

The configuration item CONFIG_CRYPTO_DEV_NX:

• prompt: Support for IBM Power7+ in-Nest cryptographic acceleration
• type: bool
• depends on: CONFIG_PPC64 && CONFIG_IBMVIO && ! CONFIG_CPU_LITTLE_ENDIAN
• defined in drivers/crypto/Kconfig
• found in Linux kernels: 3.7–3.19, 4.0–4.1
• modules built: nx-crypto

Help text

Support for Power7+ in-Nest cryptographic acceleration.

Support for Power7+ in-Nest cryptographic acceleration found in drivers/crypto/Kconfig

The configuration item CONFIG_CRYPTO_DEV_NX:

• prompt: Support for Power7+ in-Nest cryptographic acceleration
• type: tristate
• depends on: CONFIG_PPC64 && CONFIG_IBMVIO
• defined in drivers/crypto/Kconfig
• found in Linux kernels: 3.6
• modules built: nx-crypto

Help text

Support for Power7+ in-Nest cryptographic acceleration. This module supports acceleration for AES and SHA2 algorithms. If you choose 'M' here, this module will be called nx_crypto.
