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  following  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.
