41 .Nd Intel C600 Serial Attached SCSI driver
43 To compile this driver into your kernel,
44 place the following lines in your kernel configuration file:
45 .Bd -ragged -offset indent
50 Or, to load the driver as a module at boot, place the following line in
52 .Bd -literal -offset indent
58 driver provides support for Intel C600
62 To force legacy interrupts for all
64 driver instances, set the following tunable value in
66 .Bd -literal -offset indent
67 hw.isci.force_legacy_interrupts=1
70 To enable debugging prints from the
73 .Bd -literal -offset indent
77 variable to a value between 1 and 4 in
80 The hardware layer in the
82 driver has extensive logging capabilities
83 which are disabled by default for performance reasons.
84 These can be enabled by adding
85 .Bd -literal -offset indent
89 to the kernel configuration file.
