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.
The uk driver appeared in 386BSD 0.1.
