The ahci driver always enables 64-bit DMA addressing for the data transfer and the communication system descriptors if the HBA supports. ahci-buf-64bit-dma ahci-commu-64bit-dmaĮnables 64-bit DMA support. The ahci driver always enables the MSI (Message Signaled Interrupt) if the HBA supports. ahci-msi-enabledĮnables the MSI interrupt. See the AHCI specification for more details. The number of PRDT in the command table can be from 1 toĦ5,535. The PRDT (Physical Region Descriptor Table) contains the scatter/gather list for the data transfer. Specifies the number of PRDT in the command table. The ahci driver supports following modifiable properties: ahci-dma-prdt-number The HBA might not work properly if above properties are not correctly configured. These properties override the default settings.Ĭontact the hardware vendor before modifying these properties. The ahci driver is configured by defining properties in nf. Dell RD1000), hotplug, NCQ (Native command queuing) and Port multipliers (Silicon Image 3726/4726). TheĪhci driver currently supports hard disk, ATAPI DVD, ATAPI tape, ATAPI disk (i.e. The Intel ICH6/7/8/9 and VIA vt8251 controllers support standard SATA features. The ahci driver currently supports the Intel ICH6/7/8/9/10, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host Controller Interface 1.0 specification. The AHCI 1.0 specification describes the interface between the system software and the host controller hardware.
#AHCI SERIAL ATA CONTROLLER DRIVER SERIAL#
AHCI is an Intel-developed protocol that describes the register-level interfaceįor host controllers for serial ATA 1.0a and Serial ATA II. 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.
