.Dd January 23, 2012 .Dt ISCI 4 .Os .Sh NAME .Nm isci .Nd Intel C600 Serial Attached SCSI driver .Sh SYNOPSIS To compile this driver into your kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device scbus" .Cd "device isci" .Ed
p Or, to load the driver as a module at boot, place the following line in .Xr loader.conf 5 : d -literal -offset indent isci_load="YES" .Ed .Sh HARDWARE The .Nm driver provides support for Intel C600 .Tn SAS controllers. .Sh CONFIGURATION To force legacy interrupts for all .Nm driver instances, set the following tunable value in .Xr loader.conf 5 : d -literal -offset indent hw.isci.force_legacy_interrupts=1 .Ed .Sh DEBUGGING To enable debugging prints from the .Nm driver, set the d -literal -offset indent hw.isci.debug_level .Ed
p variable to a value between 1 and 4 in .Xr loader.conf 5 .
p The hardware layer in the .Nm driver has extensive logging capabilities which are disabled by default for performance reasons. These can be enabled by adding d -literal -offset indent options ISCI_LOGGING .Ed
p to the kernel configuration file. .Sh SEE ALSO .Xr cd 4 , .Xr ch 4 , .Xr da 4 , .Xr pci 4 , .Xr sa 4 , .Xr scsi 4 .Sh HISTORY The .Nm driver first appeared in .Fx 8.3 and 9.1. .Sh AUTHORS .An -nosplit The .Nm driver was developed by Intel and originally written by .An Jim Harris Aq jimharris@FreeBSD.org with contributions from Sohaib Ahsan and input from .An Scott Long Aq scottl@FreeBSD.org .
