ISCI(4)		       FreeBSD Kernel Interfaces Manual		       ISCI(4)

NAME
     isci -- Intel C600	Serial Attached	SCSI driver

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

	   device scbus
	   device isci

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

	   isci_load="YES"

HARDWARE
     The isci driver provides support for Intel	C600 SAS controllers.

CONFIGURATION
     To	force legacy interrupts	for all	isci driver instances, set the follow-
     ing tunable value in loader.conf(5):

	   hw.isci.force_legacy_interrupts=1

DEBUGGING
     To	enable debugging prints	from the isci driver, set the

	   hw.isci.debug_level

     variable to a value between 1 and 4 in loader.conf(5).

     The hardware layer	in the isci driver has extensive logging capabilities
     which are disabled	by default for performance reasons.  These can be
     enabled by	adding

	   options ISCI_LOGGING

     to	the kernel configuration file.
