└─>Support for VIA PadLock ACE
In linux kernel since version 2.6.12  
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.
