NAME
armv8crypto – Armv8 Cryptographic Extension driver
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 cryptography instructions to accelerate AES, SHA-1, SHA-2, and finite field arithmetic.
The processor capability is reported as AES in the Instruction Set Attributes 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).
