Virtio RNG support (CONFIG_DRIVERS_VIRTIO_RNG=y) selects CONFIG_ARCH_HAVE_RNG. On the other hand, if CONFIG_DEV_URANDOM=y, it defaults to CONFIG_DEV_URANDOM_ARCH if CONFIG_ARCH_HAVE_RNG=y. DEV_URANDOM_ARCH definition states that the implementation of the /dev/urandom should be provided by the architecture-specifig logic, including the function devurandom_register(). In this case, the /dev/urandom may refer to the same driver as /dev/random that is provided by the Virtio RNG driver, which is implemented by this commit. |
