# Hardware Random Number Generator (RNG) configuration

config HW_RANDOM
tristate "Hardware Random Number Generator Core support"
default m
---help---
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.
config HW_RANDOM_TIMERIOMEM
tristate "Timer IOMEM HW Random Number Generator support"
depends on HW_RANDOM && HAS_IOMEM
---help---
This driver provides kernel-side support for a generic Random
Number Generator used by reading a 'dumb' iomem address that
is to be read no faster than, for example, once a second;
the default FPGA bitstream on the TS-7800 has such functionality.
To compile this driver as a module, choose M here: the
module will be called timeriomem-rng.
If unsure, say Y.
config HW_RANDOM_INTEL
tristate "Intel HW Random Number Generator support"
depends on HW_RANDOM && (X86 || IA64) && PCI
default HW_RANDOM
---help---
This driver provides kernel-side support for the Random Number
Generator hardware found on Intel i8xx-based motherboards.
To compile this driver as a module, choose M here: the
module will be called intel-rng.
If unsure, say Y.
config HW_RANDOM_AMD
tristate "AMD HW Random Number Generator support"
depends on HW_RANDOM && X86 && PCI
default HW_RANDOM
---help---
This driver provides kernel-side support for the Random Number
Generator hardware found on AMD 76x-based motherboards.
To compile this driver as a module, choose M here: the
module will be called amd-rng.
If unsure, say Y.
config HW_RANDOM_GEODE
tristate "AMD Geode HW Random Number Generator support"
depends on HW_RANDOM && X86_32 && PCI
default HW_RANDOM
---help---
This driver provides kernel-side support for the Random Number
Generator hardware found on the AMD Geode LX.
To compile this driver as a module, choose M here: the
module will be called geode-rng.
If unsure, say Y.
config HW_RANDOM_N2RNG
tristate "Niagara2 Random Number Generator support"

Generator hardware found on OMAP16xx and OMAP24xx multimedia
processors.
