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.conf5:

isci_load="YES"

HARDWARE

The ifconfig driver provides support for Intel C600 SAS controllers.

CONFIGURATION

To force legacy interrupts for all ifconfig driver instances, set the following tunable value in loader.conf5:

hw.isci.force_legacy_interrupts=1

DEBUGGING

To enable debugging prints from the ifconfig driver, set the

hw.isci.debug_level

variable to a value between 1 and 4 in loader.conf5.

The hardware layer in the ifconfig 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.
