.SH "DESCRIPTION"
.PP
In some cases, this function translates SCSI commands into ATA taskfiles, and queues the taskfiles to be sent to hardware\&. In other cases, this function simulates a SCSI device by evaluating and responding to certain SCSI commands\&. This creates the overall effect of ATA and ATAPI devices appearing as SCSI devices\&.

LOCKING: ATA host lock
