NetBSD 6.1.5 - man page for isp (netbsd section 4)

ISP(4)				   BSD Kernel Interfaces Manual 			   ISP(4)

NAME
     isp -- Qlogic based SCSI and FibreChannel SCSI Host Adapters

SYNOPSIS
     isp* at pci? dev? function? (PCI)
     isp* at sbus? slot ? offset ? (SBus)
     scsibus* at isp?

DESCRIPTION
     This driver provides access to SCSI or FibreChannel devices.

     SCSI features include support for Ultra SCSI and wide mode transactions for SCSI, and LVD
     (for the ISP1080 and ISP1280),

     Fibre Channel support uses FCP SCSI profile for FibreChannel.  and uses Class 3 connections
     only.  Support is available for Public and Private loops.	Command tagging is supported for
     all (in fact, FibreChannel requires tagging).

CONFIGURATION
     An optional flags 0x80 appended to the above isp* declarations will disable the download of
     driver firmware, which means you use whatever firmware is running on the card.  If no
     firmware is running on the card, the driver cannot operate the card.

     An optional flags 0x40 appended to the above isp* declarations (can be OR'd in with the
     other config flags option) will keep the driver from looking at device or bus NVRAM settings
     (this is in case NVRAM is just wrong and you have the card in a platform where it is incon-
     venient to change NVRAM settings on the card).

AUTHORS
     The isp driver was written by Matthew Jacob for NASA/Ames Research Center.

BUGS
     The driver currently ignores some NVRAM settings.

     The driver currently doesn't do error recovery for timed out commands very gracefully.

     Sometimes, when booting, the driver gets stuck waiting for the Fibre Channel firmware to
     tell it that the loop port database is ready.  In this case you'll see an announcement that
     the loop state has a value of 0x1.  To unwedge the system, unplug and replug the fibre chan-
     nel connection, or otherwise cause a LIP (Loop Initialization Primitive sequence) - this
     will kick the firmware into getting unstuck.
