isci — Intel C600 Serial Attached SCSI driver
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"
The isci driver provides support for Intel C600 SAS controllers.
To force legacy interrupts for all isci driver instances, set the following tunable value in loader.conf(5): hw.isci.force_legacy_interrupts=1
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.
The isci driver first appeared in FreeBSD 8.3 and 9.1.
The isci driver was developed by Intel and originally written by Jim Harris <jimharris@FreeBSD.org> with contributions from Sohaib Ahsan and input from Scott Long <scottl@FreeBSD.org>. This man page was written by Jim Harris <jimharris@FreeBSD.org>.
