Ahci driver specification

Defines functional behavior and Advanced Host Controller Interface software for moving data between system memory and serial ATA devices.  · Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable advanced Serial ATA (SATA) features like Native Command Queuing and hot swap. AHCI is built into chipsets with the following controller hubs: Intel® PCHM RAID/AHCI controller hub; Intel® PCH RAID/AHCI controller hub.  · AHCI (Advance Host Controller Interface) is developed by Intel to facilitate handling SATA devices. The AHCI specification emphasizes that an AHCI controller (referred to as host bus adapter, or HBA) is designed to be a data movement engine between system memory and SATA devices. It encapsulates SATA devices and provides a standard PCI interface to the host.

It encapsulates SATA devices and provides a standard PCI interface to the host. AHCI was an important part of building momentum for SATA II technology, providing a standard controller interface that optimizes advanced SATA features that weren't available with the older Integrated Drive Electronics standard interface. Version is the most recent iteration of the AHCI specification. How AHCI works. Most motherboards have AHCI enabled by default in the Unified Extensible Firmware Interface or BIOS. Older motherboards may have IDE mode enabled by default and would need.

ahci* at jmb? DESCRIPTION. The ahci driver provides support for Serial ATA controllers conforming to the Advanced Host Controller Interface specification. 29 thg 8, Starting with ESXi and Hardware Version 10, VMware introduces a new AHCI/SATA Controller. What is AHCI? AHCI is a specification that. This specification defines the functional behavior and software interface of the Advanced Host Controller Interface (ACHI), which is a hardware mechanism that.
