+.Sh NAME
+.Nm smartpqi
+.Nd Microsemi smartpqi SCSI driver for PQI controllers
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd device pci
+.Cd device scbus
+.Cd device smartpqi
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+smartpqi_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+SCSI driver provides support for the new generation of PQI controllers from
+Microsemi.
+The
+.Nm
+driver is the first SCSI driver to implement the PQI queuing model.
+.Pp
+The
+.Nm
+driver will replace the aacraid driver for Adaptec Series 9 controllers.
+.Pp
+The
+.Pa /dev/smartpqi?
+device nodes provide access to the management interface of the controller.
+One node exists per installed card.
+.Sh HARDWARE
+Controllers supported by the
+.Nm
+driver include:
+.Pp
+.Bl -bullet -compact
+.It
+HPE Gen10 Smart Array Controller Family
+.It
+OEM Controllers based on the Microsemi Chipset
+.El
+.Sh FILES
+.Bl -tag -width /boot/kernel/aac.ko -compact

+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Fx 11.1 .
+.Sh AUTHOR

+.Aq murthy.bhat@microsemi.com
+.Sh BUGS
+The controller is not actually paused on suspend/resume.
