The host adapters are listed in the ISA and PCI 668# device configuration sections below. 669# 670# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 671# that a given bus, target, and LUN always come on line as the same 672# device unit. In earlier versions the unit numbers were assigned 673# in the order that the devices were probed on the SCSI bus. This 674# means that if you removed a disk drive, you may have had to rewrite 675# your /etc/fstab file, and also that you had to be careful when adding 676# a new disk as it may have been probed earlier and moved your device 677# configuration around. 678 679# This old behavior is maintained as the default behavior. The unit 680# assignment begins with the first non-wired down unit for a device 681# type. For example, if you wire a disk as "da3" then the first 682# non-wired disk will be assigned da4. 683 684# The syntax for wiring down devices is: 685 686# controller scbus0 at ahc0 # Single bus device 687# controller scbus1 at ahc1 bus 0 # Single bus device 688# controller scbus3 at ahc2 bus 0 # Twin bus device 689# controller scbus2 at ahc2 bus 1 # Twin bus device 690# disk da0 at scbus0 target 0 unit 0 691# disk da1 at scbus3 target 1 692# disk da2 at scbus2 target 3 693# tape st1 at scbus1 target 6 694# device cd0 at scbus? 695 696# "units" (SCSI logical unit number) that are not specified are 697# treated as if specified as LUN 0. 698 699# All SCSI devices allocate as many units as are required. 700 701# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 702# configuration and doesn't have to be explicitly configured. 703 704controller scbus0 #base SCSI code 705device ch0 #SCSI media changers 706device da0 #SCSI direct access devices (aka disks) 707device sa0 #SCSI tapes 708device cd0 #SCSI CD-ROMs 709#device od0 #SCSI optical disk 710device pass0 #CAM passthrough driver 711 712# The previous devices (ch, da, st, cd) are recognized by config. 713# config doesn't (and shouldn't) know about these newer ones, 714# so we have to specify that they are on a SCSI bus with the "at scbus?" 715# clause. 716 717device pt0 at scbus? # SCSI processor type 718device sctarg0 at scbus? # SCSI target 719 720# CAM OPTIONS: 721# debugging options: 722# -- NOTE -- If you specify one of the bus/target/lun options, you must 723# specify them all! 724# CAMDEBUG: When defined enables debugging macros 725# CAM_DEBUG_BUS: Debug the given bus.

This growth 2054# will NOT shrink. To restrict the number of queue 2055# slots to exactly what the DPT can hold at one time, 2056# enable this option. 2057# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various 2058# instruments are enabled. The tools in 2059# /usr/sbin/dpt_* assume these to be enabled. 2060# DPT_FREELIST_IS_STACK For optimal L{1,2} CPU cache utilization, enable 2061# this option. Otherwise, the transaction queue is 2062# a LIFO. I cannot measure the performance gain. 2063# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT. 2064# If you ant the driver to handle timeouts, enable 2065# this option. If your system is very busy, this 2066# option will create more trouble than solve. 2067# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to 2068# wait when timing out with the above option. 2069# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h 2070# DPT_LOST_IRQ When enabled, will try, once per second, to catch 2071# any interrupt that got lost. Seems to help in some 2072# DPT-firmware/Motherboard combinations. Minimal 2073# cost, great benefit. 2074# DPT_RESET_HBA Make "reset" actually reset the controller 2075# instead of fudging it. Only enable this if you 2076# are 100% certain you need it. 2077# DPT_SHUTDOWN_SLEEP Reset controller if a request take more than 2078# this number of seconds. Do NOT enable this 2079# unless you are really, really, really certain 2080# you need it. You are advised to call Simon (the 2081# driver author) before setting it, and NEVER, 2082# EVER set it to less than 300s (5 minutes). 2083 2084controller dpt0 2085 2086# DPT options 2087options DPT_VERIFY_HINTR 2088options DPT_RESTRICTED_FREELIST 2089#!CAM# options DPT_MEASURE_PERFORMANCE 2090options DPT_FREELIST_IS_STACK 2091#!CAM# options DPT_HANDLE_TIMEOUTS 2092options DPT_TIMEOUT_FACTOR=4 2093options DPT_INTR_DELAY=200 # Some motherboards need that 2094options DPT_LOST_IRQ 2095options DPT_RESET_HBA 2096 2097# Don't EVER set this without having talked to Simon Shapiro on the phone 2098# first. 2099options DPT_SHUTDOWN_SLEEP=500 2100 2101# USB support 2102# UHCI controller 2103controller uhci0 2104# OHCI controller 2105controller ohci0 2106# General USB code (mandatory for USB) 2107controller usb0 2108# 2109# for the moment we have to specify the priorities of the device 2110# drivers explicitly by the ordering in the list below.
