-.Sh NAME
-.Nm mpt
-.Nd LSI Fusion-MPT SCSI and FibreChannel host adapter driver
-.Sh SYNOPSIS
-.Cd "mpt* at pci?"
-.Cd "scsibus* at mpt?"
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support
-for the LSI Logic Fusion-MPT family of
-.Tn SCSI
-and
-.Tn Fibre Channel
-controllers:

-Emulated in VMWare ESX Server 2
-.El
-.Pp
-The LSI Logic SCSI and Fibre Channel controllers contain firmware that presents
-a multiprotocol service layer based on the LSI Logic Fusion-MPT architecture.
-The firmware isolates the host drivers from the hardware and controls the
-device side of the message passing interface to the host device drivers.
-The firmware manages all phases of an I/O request and optimizes the interrupt
-management for the system.
-For Fibre Channel, the firmware also manages all FC-2 through FC-4 services,
-which minimizes the amount of Fibre Channel unique services required with the
-host driver.
-.Pp
-The MPI (Message Passing Interface) definition includes a register-level
-transport mechanism and a messaging protocol.
-A system doorbell and message queues define the MPI transport interface.
-Inbound Message Frames (MF), allocated in host memory, identify I/O operations
-to be performed by the IO Controller (IOC).
-These operations are queued on the Request Queue by the host driver.
-Outbound Message Frames, also in host memory, track I/O operations as they
-complete.
-These frames are queued on the Reply Queue by the IOC.
-A doorbell mechanism is provided for IOC configuration, reset management,
-and IOC status.
