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. SEE ALSO
ioctl(2), cd(4), ch(4), scsi(4), sd(4), ss(4), st(4) HISTORY
The uk driver appeared in 386BSD 0.1. BSD
October 11, 1993 BSD
