Driver Drone

If the contents of either the name property or the compatible property match a driver on the system, then that driver is bound to the device node. Upon completion of the command, the HBA driver should call the pkt completion routine. There are two possible values:. A proper disk controller only allows a disk to talk to the same bus. In addition to incorporating SCSA HBA entry points, structures, and functions into a driver, HBA driver developers must also concern themselves with issues surrounding driver dependency and configuration. The target driver can request the current setting of the capability for a particular target by setting the whom parameter to nonzero.

Target device refers to a device on a SCSI bus, such as a disk or a tape drive. The disk property can be used to define the type of disk supported by cmdk. The binding name is the name that links a driver to a unique device node in the device information tree.

Finally, the driver should report that this instance of the device is attached and return success.
