2016-04-20crypto4xx: integrate ppc4xx-rng into crypto4xxChristian Lamparter1-1/+0
This patch integrates the ppc4xx-rng driver into the existing crypto4xx. This is because the true random number generator is controlled and part of the security core. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Add support for STMicroelectronics STM32 random number generator. The config value defaults to N, reflecting the fact that STM32 is a very low resource microcontroller platform and unlikely to be targeted by any "grown up" defconfigs.

2014-04-16hwrng: picoxcell - remove unbuildable picoxcell TRNGPaul Bolle1-1/+0
The driver for the "Picochip picoXcell true random number generator" was added in v2.6.39. Its Kconfig symbol has always depended on PICOXCELL_PC3X3. But that Kconfig symbol has never been part of the tree. This means this driver has never been buildable. Let's remove it. It can be re-added if its dependencies are actually part of the tree.

2013-10-11hwrng: Add a driver for the hwrng found in power7+ systemsMichael Ellerman1-0/+1
Add a driver for the hwrng found in power7+ systems, based on the existing code for the arch_get_random_long() hook. We only register a single instance of the driver, not one per device, because we use the existing per_cpu array of devices in the arch code. This means we always read from the "closest" device, avoiding inter-chip memory traffic.

2009-02-22hwrng: timeriomem - New driverAlexander Clouter1-0/+1
Some hardware platforms, the TS-7800[1] is one for example, can supply the kernel with an entropy source, albeit a slow one for TS-7800 users, by just reading a particular IO address. This source must not be read above a certain rate otherwise the quality suffers. The driver is then hooked into by calling platform_device_(register|add|del) passing a structure similar to: ------ static struct timeriomem_rng_data ts78xx_ts_rng_data = { .address = (u32 *__iomem) TS_RNG, .period = 1000000, /* one second */ }; static struct platform_device ts78xx_ts_rng_device = { .name = "timeriomem_rng", .id = -1, .dev = { .platform_data = &ts78xx_ts_rng_data, }, .num_resources = 0, }; ------ [1] http://www.embeddedarm.com/products/board-detail.php?product=TS-7800 Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-05-30virtio: An entropy device, as suggested by hpa.Rusty Russell1-0/+1
Note that by itself, having a "hardware" random generator does very little: you should probably run "rngd" in your guest to feed this into the kernel entropy pool. Included: virtio_rng: dont use vmalloced addresses for virtio If virtio_rng is build as a module, random_data is an address in vmalloc space. As virtio expects guest real addresses, this can cause any kind of funny behaviour, so lets allocate random_data dynamically with kmalloc.
