9 Some VIA processors come with an integrated crypto engine
10 (so called VIA PadLock ACE, Advanced Cryptography Engine)
11 that provides instructions for very fast cryptographic
12 operations with supported algorithms.
13
14 The instructions are used only when the CPU supports them.
15 Otherwise software encryption is used.
16
17 Selecting M for this option will compile a helper module
18 padlock.ko that should autoload all below configured
19 algorithms. Don't worry if your hardware does not support
20 some or all of them. In such case padlock.ko will
21 simply write a single line into the kernel log informing
22 about its failure but everything will keep working fine.
23
24 If you are unsure, say M. The compiled module will be
25 called padlock.ko

61 Say 'Y' here to use the AMD Geode LX processor on-board AES
62 engine for the CryptoAPI AES alogrithm.
63
64 To compile this driver as a module, choose M here: the module
65 will be called geode-aes.
