Jan Beulichfed806f2006-12-06 20:38:20 -080011 To compile this driver as a module, choose M here: the
David Brownell537878d2008-03-24 12:29:51 -070012 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.

27 This driver provides kernel-side support for a generic Random
28 Number Generator used by reading a 'dumb' iomem address that
