54 * Implement each SATA port as its own SCSI bus on CAM. This way we can
55 * implement future port multiplier features as individual devices on the
56 * bus.
57 *
58 * Much of the cdb<->xa conversion code was taken from OpenBSD, the rest
59 * was written natively for DragonFly.

60 *
61 * NOTE-1: I was temporarily unlocking the port while making the CCB
62 * callback, to reduce the chance of a deadlock and to improve
63 * performance by allowing new commands to be queued.
64 *
65 * However, this also creates an opening where another AHCI
66 * interrupt can come in and execute the ahci_port_intr()
67 * function, creating a huge mess in the sequencing of the
68 * chipset.
69 *
70 * So for now we don't do this. XXX
