The Airoha SoC provide a True RNG modulethat can output 4 bytes of raw data at times.The module makes use of various noise source to provide True RandomNumber Generation.On probe the module is reset to operate Health Test and verify correctexecution of it.The module can also provide DRBG function but the execution mode ismutually exclusive, running as TRNG doesn't permit to also run it asDRBG.Signed-off-by: Christian Marangi Reviewed-by: Martin Kaiser Signed-off-by: Herbert Xu List of files: /linux/drivers/char/hw_random/Makefile

Tue, 30 Jul 2024 18:11:04 +0200

hwrng: rockchip - add hwrng driver for Rockchip RK3568 SoCRockchip SoCs used to have a random number generator as part of theircrypto device, and support for it has to be added to the correspondingdriver. However newer Rockchip SoCs like the RK3568 have an independentTrue 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 FIPS140-2 test returns a lot of failures. They can be reduced by increasingRK_RNG_SAMPLE_CNT, in a tradeoff between quality and speed. This valuehas been adjusted to get ~90% of successes and the quality value hasbeen set accordingly.Signed-off-by: Aurelien Jarno [daniel@makrotpia.org: code style fixes]Signed-off-by: Daniel Golle Acked-by: Krzysztof Kozlowski Signed-off-by: Herbert Xu List of files: /linux/drivers/char/hw_random/Makefile

hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.cMove to drivers/char/hw_random since histb-(t)rng does not providecryptography pseudo rng.histb-rng is pretty like hisi-rng, but after investigation, we confirmthere is no RNG_PHY_SEED register on histb-rng so a separate driver isneeded.Still we rename relevant function names to match those in hisi-rng.Link: https://lore.kernel.org/r/20230401164448.1393336-1-mmyangfl@gmail.comSigned-off-by: David Yang Signed-off-by: Herbert Xu List of files: /linux/drivers/char/hw_random/Makefile

Sat, 31 Jul 2021 22:48:45 +0200

hwrng: Add Arm SMCCC TRNG based driverThe "Arm True Random Number Generator Firmware Interface"[1] providesan SMCCC based interface to a true hardware random number generator.So far we are using that in arch_get_random_seed(), but it might beuseful to expose the entropy through the /dev/hwrng device as well. Thisallows 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 happilycoexist with the arch_get_random_seed() bits.[1] https://developer.arm.com/documentation/den0098/latest/Signed-off-by: Andre Przywara Reviewed-by: Ard Biesheuvel Reviewed-by: Mark Brown Signed-off-by: Herbert Xu List of files: /linux/drivers/char/hw_random/Makefile
