ISCI(4) BSD 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 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.
