uk4
Scsi user-level driver
Usage
uk* at scsibus?
Overview
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.
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
Diagnostics
All scsi(4) debug ioctls work on uk devices.
