2 # Hardware Random Number Generator (RNG) configuration
6 tristate "Hardware Random Number Generator Core support"
9 Hardware Random Number Generator Core infrastructure.
11 To compile this driver as a module, choose M here: the
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.
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

29 Generator hardware found on Intel i8xx-based motherboards.
31 To compile this driver as a module, choose M here: the
32 module will be called intel-rng.
37 tristate "AMD HW Random Number Generator support"
38 depends on HW_RANDOM && X86 && PCI
41 This driver provides kernel-side support for the Random Number
42 Generator hardware found on AMD 76x-based motherboards.

50 tristate "AMD Geode HW Random Number Generator support"
51 depends on HW_RANDOM && X86_32 && PCI
54 This driver provides kernel-side support for the Random Number
55 Generator hardware found on the AMD Geode LX.
57 To compile this driver as a module, choose M here: the
58 module will be called geode-rng.
62 config HW_RANDOM_N2RNG
63 tristate "Niagara2 Random Number Generator support"
64 depends on HW_RANDOM && SPARC64
67 This driver provides kernel-side support for the Random Number

89 tristate "Intel IXP4xx NPU HW Random Number Generator support"
90 depends on HW_RANDOM && ARCH_IXP4XX
93 This driver provides kernel-side support for the Random
94 Number Generator hardware found on the Intel IXP4xx NPU.
96 To compile this driver as a module, choose M here: the
97 module will be called ixp4xx-rng.
101 config HW_RANDOM_OMAP
102 tristate "OMAP Random Number Generator support"

117 depends on HW_RANDOM && PPC_PASEMI
120 This driver provides kernel-side support for the Random Number
121 Generator hardware found on PA Semi PWRficient SoCs.
123 To compile this driver as a module, choose M here: the
124 module will be called pasemi-rng.
128 config HW_RANDOM_VIRTIO
129 tristate "VirtIO Random Number Generator support"
