NAME

ahci - Advanced Host Controller Interface SATA controller driver
 

SYNOPSIS

sata@unit-address 

DESCRIPTION

The ahci driver is a SATA framework-compliant HBA driver that supports SATA HBA controllers that are compatible with the Advanced Host Controller Interface 1.0 specification. AHCI is an Intel-developed protocol that describes the register-level interface for host controllers for serial ATA 1.0a and Serial ATA II. The AHCI 1.0 specification describes the interface between the system software and the host controller hardware.

The ahci driver currently supports the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host Controller Interface 1.0 specification. Note that while the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers support standard SATA features, the ahci driver currently only supports hard disk, ATAPI SATA DVD, hotplug and NCQ (Native command queuing). Port multiplier and power management are not yet supported.  

CONFIGURATION

The ahci module contains no user configurable parameters.
