| 9 | Some VIA processors come with an integrated crypto engine | |
| 10 | (so called VIA PadLock ACE, Advanced Cryptography Engine) | |
| 1191f0a4 ML |
11 | that provides instructions for very fast cryptographic |
| 12 | operations with supported algorithms. | |
| 1da177e4 LT |
13 | |
| 14 | The instructions are used only when the CPU supports them. | |
| 5644bda5 ML |
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 | |
