When this is compiled in it is run too early to do anything useful: [ 6.052000] padlock: No VIA PadLock drivers have been loaded. [ 6.052000] padlock: Using VIA PadLock ACE for AES algorithm. [ 6.052000] padlock: Using VIA PadLock ACE for SHA1/SHA256 algorithms. When it's a module it isn't doing anything special, the same functionality can be provided in userspace by "probeall padlock padlock-aes padlock-sha" in modules.conf if it is required.

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.

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.
