8 ahci \- Advanced Host Controller Interface SATA controller driver
12 \fBsata@unit-address\fR
18 The \fBahci\fR driver is a SATA framework-compliant HBA driver that supports
19 SATA HBA controllers that are compatible with the \fIAdvanced Host Controller
20 Interface 1.0\fR specification. AHCI is an Intel-developed protocol that
21 describes the register-level interface for host controllers for serial ATA 1.0a
22 and Serial ATA II. The \fIAHCI 1.0\fR specification describes the interface
23 between the system software and the host controller hardware.
26 The \fBahci\fR driver currently supports the Intel ICH6/7/8/9/10, VIA vt8251
27 and JMicron AHCI controllers which are compliant with the Advanced Host
28 Controller Interface 1.0 specification. The Intel ICH6/7/8/9 and VIA vt8251
29 controllers support standard SATA features. The \fBahci\fR driver currently
30 supports hard disk, ATAPI DVD, ATAPI tape, ATAPI disk (i.e. Dell RD1000),
31 hotplug, NCQ (Native command queuing) and Port multipliers (Silicon Image
32 3726/4726). Power management is not yet supported.
36 The \fBahci\fR module contains no user configurable parameters.
