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.
