13 The ahci driver is a SATA framework-compliant HBA driver that supports
14 SATA HBA controllers that are compatible with the Advanced Host Con‐
15 troller Interface 1.0 specification. AHCI is an Intel-developed proto‐
16 col that describes the register-level interface for host controllers
17 for serial ATA 1.0a and Serial ATA II. The AHCI 1.0 specification
18 describes the interface between the system software and the host con‐
19 troller hardware.

22 The ahci driver currently supports the Intel ICH6/7/8/9/10, VIA vt8251
23 and JMicron AHCI controllers which are compliant with the Advanced Host
24 Controller Interface 1.0 specification. The Intel ICH6/7/8/9 and VIA
25 vt8251 controllers support standard SATA features. The ahci driver cur‐
26 rently supports hard disk, ATAPI DVD, ATAPI tape, ATAPI disk (i.e. Dell
27 RD1000), hotplug, NCQ (Native command queuing) and Port multipliers
28 (Silicon Image 3726/4726). Power management is not yet supported.
