The host adapters are listed in the ISA and PCI 692# device configuration sections below. 693# 694# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 695# that a given bus, target, and LUN always come on line as the same 696# device unit. In earlier versions the unit numbers were assigned 697# in the order that the devices were probed on the SCSI bus. This 698# means that if you removed a disk drive, you may have had to rewrite 699# your /etc/fstab file, and also that you had to be careful when adding 700# a new disk as it may have been probed earlier and moved your device 701# configuration around. 702 703# This old behavior is maintained as the default behavior. The unit 704# assignment begins with the first non-wired down unit for a device 705# type. For example, if you wire a disk as "da3" then the first 706# non-wired disk will be assigned da4. 707 708# The syntax for wiring down devices is: 709 710# controller scbus0 at ahc0 # Single bus device 711# controller scbus1 at ahc1 bus 0 # Single bus device 712# controller scbus3 at ahc2 bus 0 # Twin bus device 713# controller scbus2 at ahc2 bus 1 # Twin bus device 714# disk da0 at scbus0 target 0 unit 0 715# disk da1 at scbus3 target 1 716# disk da2 at scbus2 target 3 717# tape sa1 at scbus1 target 6 718# device cd0 at scbus? 719 720# "units" (SCSI logical unit number) that are not specified are 721# treated as if specified as LUN 0. 722 723# All SCSI devices allocate as many units as are required. 724 725# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 726# configuration and doesn't have to be explicitly configured. 727 728controller scbus0 #base SCSI code 729device ch0 #SCSI media changers 730device da0 #SCSI direct access devices (aka disks) 731device sa0 #SCSI tapes 732device cd0 #SCSI CD-ROMs 733device pass0 #CAM passthrough driver 734 735# The previous devices (ch, da, st, cd) are recognized by config. 736# config doesn't (and shouldn't) know about these newer ones, 737# so we have to specify that they are on a SCSI bus with the "at scbus?" 738# clause. 739 740device pt0 at scbus? # SCSI processor type 741 742# CAM OPTIONS: 743# debugging options: 744# -- NOTE -- If you specify one of the bus/target/lun options, you must 745# specify them all! 746# CAMDEBUG: When defined enables debugging macros 747# CAM_DEBUG_BUS: Debug the given bus.

Note that the RealTek driver defaults 1623# to using programmed I/O to do register accesses because memory mapped 1624# mode seems to cause severe lockups on SMP hardware. This driver also 1625# supports the Accton EN1207D `Cheetah' adapter, which uses a chip called 1626# the MPX 5030/5038, which is either a RealTek in disguise or a RealTek 1627# workalike. 1628# 1629# The 'sf' device provides support for Adaptec Duralink PCI fast 1630# ethernet adapters based on the Adaptec AIC-6915 "starfire" controller. 1631# This includes dual and quad port cards, as well as one 100baseFX card. 1632# Most of these are 64-bit PCI devices, except for one single port 1633# card which is 32-bit. 1634# 1635# The 'ste' device provides support for adapters based on the Sundance 1636# Technologies ST201 PCI fast ethernet controller.

This includes the SK-9841 and SK-9842 1645# single port cards (single mode and multimode fiber) and the 1646# SK-9843 and SK-9844 dual port cards (also single mode and multimode). 1647# The driver will autodetect the number of ports on the card and 1648# attach each one as a separate network interface. 1649# 1650# The 'ti' device provides support for PCI gigabit ethernet NICs based 1651# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the 1652# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others. 1653# Note that you will probably want to bump up NMBCLUSTERS a lot to use 1654# this driver. 1655# 1656# The 'tl' device provides support for the Texas Instruments TNETE100 1657# series 'ThunderLAN' cards and integrated ethernet controllers. This 1658# includes several Compaq Netelligent 10/100 cards and the built-in 1659# ethernet controllers in several Compaq Prosignia, Proliant and 1660# Deskpro systems. It also supports several Olicom 10Mbps and 10/100 1661# boards. 1662# 1663# The `tx' device provides support for the SMC 9432TX cards. 1664# 1665# The `vr' device provides support for various fast ethernet adapters 1666# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II' 1667# chips, including the D-Link DFE530TX, the Hawking Technologies PN102TX, 1668# and the AOpen/Acer ALN-320. 1669# 1670# The `vx' device provides support for the 3Com 3C590 and 3C595 1671# early support 1672# 1673# The `wb' device provides support for various fast ethernet adapters 1674# based on the Winbond W89C840F chip. Note: this is not the same as 1675# the Winbond W89C940F, which is an NE2000 clone. 1676# 1677# The `xl' device provides support for the 3Com 3c900, 3c905 and 1678# 3c905B (Fast) Etherlink XL cards and integrated controllers. This 1679# includes the integrated 3c905B-TX chips in certain Dell Optiplex and 1680# Dell Precision desktop machines and the integrated 3c905-TX chips 1681# in Dell Latitude laptop docking stations. 1682# 1683# The `fpa' device provides support for the Digital DEFPA PCI FDDI 1684# adapter. pseudo-device fddi is also needed. 1685# 1686# The `meteor' device is a PCI video capture board.

This growth 2197# will NOT shrink. To restrict the number of queue 2198# slots to exactly what the DPT can hold at one time, 2199# enable this option. 2200# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various 2201# instruments are enabled. The tools in 2202# /usr/sbin/dpt_* assume these to be enabled. 2203# DPT_FREELIST_IS_STACK For optimal L{1,2} CPU cache utilization, enable 2204# this option. Otherwise, the transaction queue is 2205# a LIFO. I cannot measure the performance gain. 2206# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT. 2207# If you ant the driver to handle timeouts, enable 2208# this option. If your system is very busy, this 2209# option will create more trouble than solve. 2210# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to 2211# wait when timing out with the above option. 2212# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h 2213# DPT_LOST_IRQ When enabled, will try, once per second, to catch 2214# any interrupt that got lost. Seems to help in some 2215# DPT-firmware/Motherboard combinations. Minimal 2216# cost, great benefit. 2217# DPT_RESET_HBA Make "reset" actually reset the controller 2218# instead of fudging it. Only enable this if you 2219# are 100% certain you need it. 2220# DPT_SHUTDOWN_SLEEP Reset controller if a request take more than 2221# this number of seconds. Do NOT enable this 2222# unless you are really, really, really certain 2223# you need it.
