UK(4)                   NetBSD Kernel Interfaces Manual                  UK(4)


NAME

     uk - SCSI user-level driver


SYNOPSIS

     uk* at scsibus? target ? lun ?


DESCRIPTION

     The uk driver provides support for a process to address devices on the
     SCSI bus for which there is no configured driver.

     A SCSI adapter must also be separately configured into the system before
     this driver makes sense.


KERNEL CONFIGURATION

     If a count is given, that number of uk devices will be configured into
     the NetBSD kernel.


IOCTLS

     The uk driver has no ioctls of its own but rather acts as a medium for
     the generic scsi(4) ioctls.  These are described in <sys/scsiio.h>.


FILES

     /dev/uk[0-255]  unknown SCSI devices.


DIAGNOSTICS

     All scsi(4) debug ioctls work on uk devices.
