uk -- SCSI user-level driver
uk* at scsibus? target ? lun ?
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.
If a count is given, that number of uk devices will be configured into the NetBSD kernel.
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>.
/dev/uk[0-255] unknown SCSI devices.
All scsi(4) debug ioctls work on uk devices.
ioctl(2), cd(4), ch(4), scsi(4), sd(4), ss(4), st(4)
The uk driver appeared in 386BSD 0.1. NetBSD 8.1 October 11, 1993 NetBSD 8.1
