ISCI(4)			    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  fol-
       lowing 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 capabili-
       ties which are disabled by default for performance reasons.  These  can
       be enabled by adding

	     options ISCI_LOGGING

       to the kernel configuration file.
