Host Adapter Facilities
The principal difference between a SCSI driver and other kernel-level drivers is that, while other kinds of drivers are expected to control devices directly using PIO and DMA, a SCSI driver operates its devices indirectly, by making function calls to the host adapter driver. This section documents the functional interface to the host adapter driver.
