9 | Hardware Random Number Generator Core infrastructure. | |
10 | ||
fed806f4 | 11 | To compile this driver as a module, choose M here: the |
537878d2 DB |
12 | module will be called rng-core. This provides a device |
13 | that's usually called /dev/hw_random, and which exposes one | |
14 | of possibly several hardware random number generators. | |
15 | ||
16 | These hardware random number generators do not feed directly | |
17 | into the kernel's random number generator. That is usually | |
18 | handled by the "rngd" daemon. Documentation/hw_random.txt | |
19 | has more information. | |
