9 Some VIA processors come with an integrated crypto engine
10 (so called VIA PadLock ACE, Advanced Cryptography Engine)
Michal Ludvig1191f0a2006-08-06 22:46:20 +100011 that provides instructions for very fast cryptographic
12 operations with supported algorithms.
Linus Torvalds1da177e2005-04-16 15:20:36 -070013
14 The instructions are used only when the CPU supports them.
Michal Ludvig5644bda2006-08-06 22:50:30 +100015 Otherwise software encryption is used.

56 To compile this driver as a module, choose M here: the module
57 will be called geode-aes.
