menuconfig CRYPTO_HW bool "Hardware crypto devices" default y ---help--- Say Y here to get to see options for hardware crypto devices and processors. This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled. if CRYPTO_HW config CRYPTO_DEV_PADLOCK tristate "Support for VIA PadLock ACE" depends on X86_32 select CRYPTO_ALGAPI help Some VIA processors come with an integrated crypto engine (so called VIA PadLock ACE, Advanced Cryptography Engine) that provides instructions for very fast cryptographic operations with supported algorithms. The instructions are used only when the CPU supports them. Otherwise software encryption is used. config CRYPTO_DEV_PADLOCK_AES tristate "PadLock driver for AES algorithm" depends on CRYPTO_DEV_PADLOCK select CRYPTO_BLKCIPHER help Use VIA PadLock for AES algorithm. Available in VIA C3 and newer CPUs. If unsure say M. The compiled module will be called padlock-aes.ko config CRYPTO_DEV_PADLOCK_SHA tristate "PadLock driver for SHA1 and SHA256 algorithms" depends on CRYPTO_DEV_PADLOCK select CRYPTO_SHA1 select CRYPTO_SHA256 help Use VIA PadLock for SHA1/SHA256 algorithms. Available in VIA C7 and newer processors. If unsure say M. The compiled module will be called padlock-sha.ko source "arch/s390/crypto/Kconfig" config CRYPTO_DEV_GEODE tristate "Support for the Geode LX AES engine" depends on X86_32 && PCI select CRYPTO_ALGAPI select CRYPTO_BLKCIPHER help Say 'Y' here to use the AMD Geode LX processor on-board AES engine for the CryptoAPI AES algorithm. To compile this driver as a module, choose M here: the module will be called geode-aes. config ZCRYPT tristate "Support for PCI-attached cryptographic adapters" depends on S390 select ZCRYPT_MONOLITHIC if ZCRYPT="y" help Select this option if you want to use a PCI-attached cryptographic adapter like: + PCI Cryptographic Accelerator (PCICA) + PCI Cryptographic Coprocessor (PCICC) + PCI-X Cryptographic Coprocessor (PCIXCC) + Crypto Express2 Coprocessor (CEX2C) + Crypto Express2 Accelerator (CEX2A) config ZCRYPT_MONOLITHIC bool "Monolithic zcrypt module" depends on ZCRYPT="m" help Select this option if you want to have a single module z90crypt.ko that contains all parts of the crypto device driver (ap bus, request router and all the card drivers). config CRYPTO_DEV_HIFN_795X tristate "Driver HIFN 795x crypto accelerator chips" select CRYPTO_DES select CRYPTO_ALGAPI select CRYPTO_BLKCIPHER depends on PCI help This option allows you to have support for HIFN 795x crypto adapters. endif # CRYPTO_HW
