NAME

6       ahci - Advanced Host Controller Interface SATA controller driver

SYNOPSIS

DESCRIPTION

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.
