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:

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).
