The device is split * into two parts. The first part implements the register interface for the * guest and the second one does the data transfer. * * The guest can access the controller in two ways. The first one is the native * way implementing the registers described in the AHCI specification and is * the preferred one. The second implements the I/O ports used for booting from * the hard disk and for guests which don't have an AHCI SATA driver. * * The data is transferred in an asynchronous way using one thread per implemented * port or using the new async completion interface which is still under * development.
