Hardware Random Number Generator Core infrastructure.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called rng-core. This provides a device
|
|
that's usually called /dev/hw_random, and which exposes one
|
|
of possibly several hardware random number generators.
|
|
|
|
These hardware random number generators do not feed directly
|
|
into the kernel's random number generator. That is usually
|
|
handled by the "rngd" daemon. Documentation/hw_random.txt
|
|
has more information.
|
|
|
|
If unsure, say Y.
