5# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
6# 'makeoptions', 'hints', etc. go into the kernel configuration that you
7# run config(8) with.
8#
9# Lines that begin with 'hint.' are NOT for config(8), they go into your
10# hints file. See /boot/device.hints and/or the 'hints' config(8) directive.

20# NOTES conventions and style guide:
21#
22# Large block comments should begin and end with a line containing only a
23# comment character.
24#
25# To describe a particular object, a block comment (if it exists) should
26# come first. Next should come device, options, and hints lines in that
27# order. All device and option lines must be described by a comment that
28# doesn't just expand the device or option name. Use only a concise
29# comment on the same line if possible. Very detailed descriptions of
30# devices and subsystems belong in man pages.
31#
32# A space followed by a tab separates 'options' from an option name. Two
33# spaces followed by a tab separate 'device' from a device name. Comments
34# after an option or device should use one space after the comment character.
35# To comment out a negative option that disables code and thus should not be
36# enabled for LINT builds, precede 'options' with "#!".
37#

41# be the same as the name of your kernel.

46# The `maxusers' parameter controls the static sizing of a number of

66# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
67# after most other flags. Here we use it to inhibit use of non-optimal
68# gcc built-in functions (e.g., memcmp).
69#
70# DEBUG happens to be magic.
71# The following is equivalent to 'config -g KERNELNAME' and creates

74# but that isn't normally necessary as the debug symbols are not loaded
75# by the kernel and are not useful there anyway.
76#

90# FreeBSD processes are subject to certain limits to their consumption

93# The soft limits can be modified during normal system operation, but
94# the hard limits are set at boot time. Their default values are

593# soon to have a new base RFC and many many more
594# extensions. This release supports all the extensions
595# including many drafts (most about to become RFC's).
596# It is the reference implementation of SCTP
597# and is quite well tested.
598#
599# Note YOU MUST have both INET and INET6 defined.
600# You don't have to enable V6, but SCTP is
601# dual stacked and so far we have not torn apart
602# the V6 and V4.. since an association can span
603# both a V6 and V4 address at the SAME time :-)

606# There are bunches of options:
607# this one turns on all sorts of
608# nastly printing that you can
609# do. It's all controlled by a
610# bit mask (settable by socket opt and
611# by sysctl). Including will not cause
612# logging until you set the bits.. but it
613# can be quite verbose.. so without this
614# option we don't do any of the tests for
615# bits and prints.. which makes the code run
616# faster.. if you are not debugging don't use.

621# has not done this. Its more for experimentation to
622# see how much CPU the CRC32c really takes. Most new
623# cards for TCP support checksum offload.. so this
624# option gives you a "view" into what SCTP would be
625# like with such an offload (which only exists in
626# high in iSCSI boards so far). With the new

1187# SCSI DEVICES
1188
1189# SCSI DEVICE CONFIGURATION
1190
1191# The SCSI subsystem consists of the `base' SCSI code, a number of
1192# high-level SCSI device `type' drivers, and the low-level host-adapter
1193# device drivers. The host adapters are listed in the ISA and PCI
1194# device configuration sections below.
1195#
1196# It is possible to wire down your SCSI devices so that a given bus,
1197# target, and LUN always come on line as the same device unit. In
1198# earlier versions the unit numbers were assigned in the order that
1199# the devices were probed on the SCSI bus. This means that if you
1200# removed a disk drive, you may have had to rewrite your /etc/fstab
1201# file, and also that you had to be careful when adding a new disk
1202# as it may have been probed earlier and moved your device configuration
1203# around. (See also option GEOM_VOL for a different solution to this
1204# problem.)
1205
1206# This old behavior is maintained as the default behavior. The unit
1207# assignment begins with the first non-wired down unit for a device
1208# type. For example, if you wire a disk as "da3" then the first
1209# non-wired disk will be assigned da4.
1210
1211# The syntax for wiring down devices is:

1246#
1247# The pt driver drives SCSI Processor devices.
1248#
1249# The sg driver provides a passthrough API that is compatible with the
1250# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1251# option to run linux SG apps. It can also stand on its own and provide
1252# source level API compatiblity for porting apps to FreeBSD.
1253#
1254# Target Mode support is provided here but also requires that a SIM
1255# (SCSI Host Adapter Driver) provide support as well.
1256#
1257# The targ driver provides target mode support as a Processor type device.
1258# It exists to give the minimal context necessary to respond to Inquiry
1259# commands. There is a sample user application that shows how the rest
1260# of the command support might be done in /usr/share/examples/scsi_target.
1261#
1262# The targbh driver provides target mode support and exists to respond
1263# to incoming commands that do not otherwise have a logical unit assigned
1264# to them.

1597# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1598# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1599# The DPT controllers are commonly re-licensed under other brand-names -
1600# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1601# Compaq are actually DPT controllers.
1602#
1603# See src/sys/dev/dpt for debugging and other subtle options.
1604# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1605# instruments are enabled. The tools in
1606# /usr/sbin/dpt_* assume these to be enabled.
1607# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1608# If you want the driver to handle timeouts, enable
1609# this option. If your system is very busy, this
1610# option will create more trouble than solve.
1611# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1612# wait when timing out with the above option.
1613# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1614# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1615# any interrupt that got lost. Seems to help in some
1616# DPT-firmware/Motherboard combinations. Minimal
1617# cost, great benefit.
1618# DPT_RESET_HBA Make "reset" actually reset the controller
1619# instead of fudging it. Only enable this if you
1620# are 100% certain you need it.

20# NOTES conventions and style guide:
21#
22# Large block comments should begin and end with a line containing only a
23# comment character.
24#
25# To describe a particular object, a block comment (if it exists) should
26# come first. Next should come device, options, and hints lines in that
27# order. All device and option lines must be described by a comment that
28# doesn't just expand the device or option name. Use only a concise
29# comment on the same line if possible. Very detailed descriptions of
30# devices and subsystems belong in man pages.
31#
32# A space followed by a tab separates 'options' from an option name. Two
33# spaces followed by a tab separate 'device' from a device name. Comments
34# after an option or device should use one space after the comment character.
35# To comment out a negative option that disables code and thus should not be
36# enabled for LINT builds, precede 'options' with "#!".
37#

1187# SCSI DEVICES

1189# SCSI DEVICE CONFIGURATION
1190
1191# The SCSI subsystem consists of the `base' SCSI code, a number of
1192# high-level SCSI device `type' drivers, and the low-level host-adapter
1193# device drivers. The host adapters are listed in the ISA and PCI
1194# device configuration sections below.
1195#
1196# It is possible to wire down your SCSI devices so that a given bus,
1197# target, and LUN always come on line as the same device unit. In
1198# earlier versions the unit numbers were assigned in the order that
1199# the devices were probed on the SCSI bus. This means that if you
1200# removed a disk drive, you may have had to rewrite your /etc/fstab
1201# file, and also that you had to be careful when adding a new disk
1202# as it may have been probed earlier and moved your device configuration
1203# around. (See also option GEOM_VOL for a different solution to this
1204# problem.)
1205
1206# This old behavior is maintained as the default behavior. The unit
1207# assignment begins with the first non-wired down unit for a device
1208# type. For example, if you wire a disk as "da3" then the first
1209# non-wired disk will be assigned da4.
1210
1211# The syntax for wiring down devices is:

1235# The ch driver drives SCSI Media Changer ("jukebox") devices.

1238# ("WORM") devices.

1243#
1244# The ses driver drives SCSI Environment Services ("ses") and
1245# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices.
1246#
1247# The pt driver drives SCSI Processor devices.
1248#
1249# The sg driver provides a passthrough API that is compatible with the
1250# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1251# option to run linux SG apps. It can also stand on its own and provide
1252# source level API compatiblity for porting apps to FreeBSD.
1253#
1254# Target Mode support is provided here but also requires that a SIM
1255# (SCSI Host Adapter Driver) provide support as well.
1256#
1257# The targ driver provides target mode support as a Processor type device.
1258# It exists to give the minimal context necessary to respond to Inquiry
1259# commands. There is a sample user application that shows how the rest
1260# of the command support might be done in /usr/share/examples/scsi_target.
1261#
1262# The targbh driver provides target mode support and exists to respond
1263# to incoming commands that do not otherwise have a logical unit assigned
1264# to them.
1265#
1266# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
1267# configuration as the "pass" driver.
