I've set: CONFIG_CRYPTO_DEV_HIFN_795X=m CONFIG_CRYPTO_DEV_HIFN_795X_RNG=y and after loading the module, dmesg shows: Driver for HIFN 795x crypto accelerator chip has been successfully registered. Somehow this message sounds to me, as if this MacMini does have such a chip. This would be surprising, as I thought the chip is a highly specialized one, and expensive too. Also there's no ../devices/ symlink in /sys/bus/pci/drivers/hifn795x. Still, why would the driver load into the kernel when there's no such chip? Thanks, Christian.
