.SH DESCRIPTION
.B smartpqi
is a SCSI driver for Microsemi Smart Family controllers.
-.SH OPTIONS
+.SS Supported \f[BI]ioctl\fP\/() operations
+For compatibility with applications written for the
+.BR cciss (4)
+and
+.BR hpsa (4)
+drivers, many, but not all of the
+.BR ioctl (2)
+operations supported by the
+.B hpsa
+driver are also supported by the
+.B smartpqi
+driver.
+The data structures used by these operations
+are described in the Linux kernel source file
+.IR include/linux/cciss_ioctl.h .
+.TP
+.BR CCISS_DEREGDISK ", " CCISS_REGNEWDISK ", " CCISS_REGNEWD
+These operations
+all do exactly the same thing, which is to cause the driver to re-scan
+for new devices.
+This does exactly the same thing as writing to the
+.BR smartpqi -specific
+host
+.I rescan
+attribute.
+.TP
+.B CCISS_GETPCIINFO
+This operation Returns the PCI domain, bus,
+device and function and "board ID" (PCI subsystem ID).
+.TP
+.B CCISS_GETDRIVVER
+This operation returns the driver version in four bytes, encoded as:
+.IP
+.in +4n
+.EX
+(major_version << 28) | (minor_version << 24) |
+ (release << 16) | revision
+.EE
+.in
+.TP
+.B CCISS_PASSTHRU
+Allows BMIC and CISS commands to be passed through to the controller.
+.SS Boot options
.TP
.BR disable_device_id_wildcards= { 0 | 1 }
Disables support for device ID wildcards.

-.SH CONFIGURATION
-To configure Microsemi Smart Family controllers, please refer to the
-controller's User Guide documentation.

-.\" Does this manual have a title? Is it freely available online?

.SS Device nodes
Logical drives are accessed via the SCSI disk driver
The
.I ssd_smart_path_enabled
attribute is read-only.
-.\" FIXME
-.\" What is "ioaccel"? This string appears nowhere in man-pages HEAD.
This attribute is for ioaccel-enabled volumes.
+(Ioaccel is an alternative driver submission path that allows the
+driver to send I/O requests directly to backend SCSI devices,
+bypassing the controller firmware.
+This results in an increase in performance.
+This method is used for HBA disks and for logical volumes comprised of SSDs.)
Contains 1 if ioaccel is enabled for the volume and 0 otherwise.
