<p class="Pp">This driver provides the <a class="Xr">CAM(4)</a> subsystem with
native access to the SATA ports of controller. Each SATA port is represented
to CAM as a separate bus with 16 targets. Most of the bus-management details
are handled by the SATA-specific transport of CAM. Connected ATA disks are
handled by the ATA protocol disk peripheral driver <a class="Xr">ada(4)</a>.
ATAPI devices are handled by the SCSI protocol peripheral drivers
<a class="Xr">cd(4)</a>, <a class="Xr">da(4)</a>, <a class="Xr">sa(4)</a>,
etc.</p>
<p class="Pp">Driver features include support for Serial ATA and ATAPI devices,
Port Multipliers (including FIS-based switching), hardware command queues
(31 command per port), Native Command Queuing, SATA interface Power
Management, device hot-plug and Message Signaled Interrupts.</p>
<p class="Pp">The activity LEDs of the adapters supported by the
<code class="Nm">siis</code> driver can be controlled via the
<a class="Xr">led(4)</a> API for localization or status reporting
purposes.</p>
