# # 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 ppc4xx-rng. If unsure, say N. config UML_RANDOM depends on UML tristate "Hardware random number generator" help This option enables UML's "hardware" random number generator. It attaches itself to the host's /dev/random, supplying as much entropy as the host has, rather than the small amount the UML gets from its own drivers. It registers itself as a standard hardware random number generator, major 10, minor 183, and the canonical device name is /dev/hwrng. The way to make use of this is to install the rng-tools package (check your distro, or download from http://sourceforge.net/projects/gkernel/). rngd periodically reads /dev/hwrng and injects the entropy into /dev/random. config HW_RANDOM_PSERIES tristate "pSeries HW Random Number Generator support" depends on HW_RANDOM && PPC64 && IBMVIO default HW_RANDOM ---help--- This driver provides kernel-side support for the Random Number Generator hardware found on POWER7+ machines and above To compile this driver as a module, choose M here: the module will be called pseries-rng.
