       NAME
             sony - Sony CDU31A, CDU33A and CDU535 non-SCSI host bus
             adapter

       DESCRIPTION
             The sony host adapter subsystem enables the SCSI target
             drivers sc01 to communicate with target controllers and
             logical units. This driver implements the Portable Device
             Interface (PDI) for the sc01 PDI target driver.

             It is also possible to access the SCSI-bus subsystem directly
             using the pass-through driver interface.  This allows you to
             issue sb control blocks directly to the target controller.  To
             find the appropriate device to use, while any device is being
             accessed through the target driver, use the B_GETDEV ioctl to
             get the major and minor numbers of the pass-through node.
             This node may be created and opened for pass-through use
             (SDI_SEND ioctl).

          ioctl Calls
             The following ioctl(2) commands are supported by this driver:

             SDI_SEND
                   Sends a pass-through command (SCSI control block) to a
                   target controller, bypassing the associated target
                   driver.

             B_GETTYPE
                   Returns the bus name and device driver name of a
                   specific device.

             HA_VER
                   For a 80386-based computer, used to determine the Driver
                   Interface Version supported by the driver.  It returns
                   the structure ver_no defined in sdi.h.
