menu "Hardware crypto devices" config CRYPTO_DEV_PADLOCK tristate "Support for VIA PadLock ACE" depends on X86_32 select CRYPTO_ALGAPI default m 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. Selecting M for this option will compile a helper module padlock.ko that should autoload all below configured algorithms. Don't worry if your hardware does not support some or all of them. In such case padlock.ko will simply write a single line into the kernel log informing about its failure but everything will keep working fine. If you are unsure, say M. The compiled module will be called padlock.ko config CRYPTO_DEV_PADLOCK_AES tristate "PadLock driver for AES algorithm" depends on CRYPTO_DEV_PADLOCK select CRYPTO_BLKCIPHER default m 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 default m 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 CRYPTO && X86_32 && PCI select CRYPTO_ALGAPI select CRYPTO_BLKCIPHER default m help Say 'Y' here to use the AMD Geode LX processor on-board AES engine for the CryptoAPI AES alogrithm. To compile this driver as a module, choose M here: the module will be called geode-aes. endmenu
