hwrng: bcm74110 - Add Broadcom BCM74110 RNG driver

hwrng: airoha - add support for Airoha EN7581 TRNG

2024-10-28T10:33:10+00:00

Add support for Airoha TRNG. The Airoha SoC provide a True RNG module that can output 4 bytes of raw data at times. The module makes use of various noise source to provide True Random Number Generation. On probe the module is reset to operate Health Test and verify correct execution of it. The module can also provide DRBG function but the execution mode is mutually exclusive, running as TRNG doesn't permit to also run it as DRBG.

hwrng: rockchip - add hwrng driver for Rockchip RK3568 SoC

2024-08-10T04:25:34+00:00

Rockchip SoCs used to have a random number generator as part of their crypto device, and support for it has to be added to the corresponding driver. However newer Rockchip SoCs like the RK3568 have an independent True Random Number Generator device. This patch adds a driver for it, greatly inspired from the downstream driver. The TRNG device does not seem to have a signal conditionner and the FIPS 140-2 test returns a lot of failures. They can be reduced by increasing RK_RNG_SAMPLE_CNT, in a tradeoff between quality and speed. This value has been adjusted to get ~90% of successes and the quality value has been set accordingly.

hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.c

2023-05-12T10:48:01+00:00

Move to drivers/char/hw_random since histb-(t)rng does not provide cryptography pseudo rng. histb-rng is pretty like hisi-rng, but after investigation, we confirm there is no RNG_PHY_SEED register on histb-rng so a separate driver is needed. Still we rename relevant function names to match those in hisi-rng. Link: https://lore.kernel.org/r/20230401164448.1393336-1-mmyangfl@gmail.com Signed-off-by: David Yang Signed-off-by: Herbert Xu

hwrng: starfive - Add TRNG driver for StarFive SoC

hwrng: mpfs - add polarfire soc hwrng support

2022-04-15T08:34:28+00:00

Add a driver to access the hardware random number generator on the Polarfire SoC. The hwrng can only be accessed via the system controller, so use the mailbox interface the system controller exposes to access the hwrng. Signed-off-by: Conor Dooley Signed-off-by: Herbert Xu

hwrng: Add Arm SMCCC TRNG based driver

2021-08-06T11:45:26+00:00

The "Arm True Random Number Generator Firmware Interface"[1] provides an SMCCC based interface to a true hardware random number generator. So far we are using that in arch_get_random_seed(), but it might be useful to expose the entropy through the /dev/hwrng device as well. This allows to assess the quality of the implementation, by using "rngtest" from the rng-tools package, for example. Add a simple platform driver implementing the hw_random interface. The corresponding platform device is created by the SMCCC core code, we just match it here by name and provide a module alias. Since the firmware takes care about serialisation, this can happily coexist with the arch_get_random_seed() bits.
