20/** @page pg_dev_ahci AHCI - Advanced Host Controller Interface Emulation.
21 *
22 * This component implements an AHCI serial ATA controller. The device is split
23 * into two parts. The first part implements the register interface for the
24 * guest and the second one does the data transfer.
25 *
26 * The guest can access the controller in two ways. The first one is the native
27 * way implementing the registers described in the AHCI specification and is
28 * the preferred one. The second implements the I/O ports used for booting from
29 * the hard disk and for guests which don't have an AHCI SATA driver.
30 *
31 * The data is transfered using the extended media interface, asynchronously if
32 * it is supported by the driver below otherwise it weill be done synchronous.
33 * Either way a thread is used to process new requests from the guest.
