QAT(4)		       FreeBSD Kernel Interfaces Manual			QAT(4)

NAME
     qat -- Intel QuickAssist Technology (QAT) driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device crypto
	   device cryptodev
	   device qat

     Alternatively, to load the	driver as a module at boot time, place the
     following lines in	loader.conf(5):

	   qat_load="YES"
	   qat_c2xxxfw_load="YES"
	   qat_c3xxxfw_load="YES"
	   qat_c63xfw_load="YES"
	   qat_d15xxfw_load="YES"
	   qat_dh895xcc_load="YES"

DESCRIPTION
     The qat driver implements crypto(4) support for some of the cryptographic
     acceleration functions of the Intel QuickAssist device.  The qat driver
     supports the QAT devices integrated with Atom C2000 and C3000 and Xeon
     C620 and D-1500 chipsets, and the Intel QAT Adapter 8950.	It can accel-
     erate AES in CBC, CTR, XTS	(except	for the	C2000) and GCM modes, and can
     perform authenticated encryption combining	the CBC, CTR and XTS modes
     with SHA1-HMAC and	SHA2-HMAC.  The	qat driver can also compute SHA1 and
     SHA2 digests.

SEE ALSO
     crypto(4),	ipsec(4), pci(4), random(4), crypto(7),	crypto(9)

HISTORY
     The qat driver first appeared in FreeBSD 13.0.

AUTHORS
     The qat driver was	written	for NetBSD by Hikaru Abe <hikaru@iij.ad.jp>
     and ported	to FreeBSD by
     Mark Johnston <markj@FreeBSD.org>.

BUGS
     Some Atom C2000 QAT devices have two acceleration engines instead of one.
     The qat driver currently misbehaves when both are enabled and thus	does
     not enable	the second acceleration	engine if one is present.
