ARMV8CRYPTO(4) Kernel Interfaces Manual ARMV8CRYPTO(4) NAME armv8crypto -- driver for the AES accelerator on ARM CPUs SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device crypto device armv8crypto Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): armv8crypto_load="YES" DESCRIPTION Starting with the ARMv8 architecture ARM Limited has added optional cryp- tography instructions to accelerate AES, SHA-1, SHA-2, and finite field arithmetic. The processor capability is reported as AES in the Instruction Set Attrib- utes 0 line at boot. The armv8crypto driver does not attach on systems that lack the required CPU capability. The armv8crypto driver registers itself to accelerate AES operations for crypto(4). SEE ALSO crypt(3), crypto(4), intro(4), ipsec(4), random(4), crypto(7), crypto(9) HISTORY The armv8crypto driver first appeared in FreeBSD 11.0. AUTHORS The armv8crypto driver was written by Andrew Turner <andrew@FreeBSD.org>. FreeBSD 15.1 July 29, 2020 ARMV8CRYPTO(4)
