30/** @page pg_dev_ahci AHCI - Advanced Host Controller Interface Emulation.
31 *
32 * This component implements an AHCI serial ATA controller. The device is split
33 * into two parts. The first part implements the register interface for the
34 * guest and the second one does the data transfer.
35 *
36 * The guest can access the controller in two ways. The first one is the native
37 * way implementing the registers described in the AHCI specification and is
38 * the preferred one. The second implements the I/O ports used for booting from
39 * the hard disk and for guests which don't have an AHCI SATA driver.
40 *
41 * The data is transfered using the extended media interface, asynchronously if
42 * it is supported by the driver below otherwise it weill be done synchronous.
43 * Either way a thread is used to process new requests from the guest.
