4#
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#

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
72# 'kernel.debug' compiled with -g debugging as well as a normal

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
91# of system resources. See getrlimit(2) for more details. Each
92# resource limit has two values, a "soft" limit and a "hard" limit.
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
95# in sys/<arch>/include/vmparam.h. There are two ways to change them:
96#
97# 1. Set the values at kernel build time. The options below are one
98# way to allow that limit to grow to 1GB. They can be increased

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# nastily 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

1210# SCSI DEVICES
1211
1212# SCSI DEVICE CONFIGURATION
1213
1214# The SCSI subsystem consists of the `base' SCSI code, a number of
1215# high-level SCSI device `type' drivers, and the low-level host-adapter
1216# device drivers. The host adapters are listed in the ISA and PCI
1217# device configuration sections below.
1218#
1219# It is possible to wire down your SCSI devices so that a given bus,
1220# target, and LUN always come on line as the same device unit. In
1221# earlier versions the unit numbers were assigned in the order that
1222# the devices were probed on the SCSI bus. This means that if you
1223# removed a disk drive, you may have had to rewrite your /etc/fstab
1224# file, and also that you had to be careful when adding a new disk
1225# as it may have been probed earlier and moved your device configuration
1226# around. (See also option GEOM_VOL for a different solution to this
1227# problem.)
1228
1229# This old behavior is maintained as the default behavior. The unit
1230# assignment begins with the first non-wired down unit for a device
1231# type. For example, if you wire a disk as "da3" then the first
1232# non-wired disk will be assigned da4.
1233
1234# The syntax for wiring down devices is:

1268# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices.
1269#
1270# The pt driver drives SCSI Processor devices.
1271#
1272# The sg driver provides a passthrough API that is compatible with the
1273# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1274# option to run linux SG apps. It can also stand on its own and provide
1275# source level API compatibility for porting apps to FreeBSD.
1276#
1277# Target Mode support is provided here but also requires that a SIM
1278# (SCSI Host Adapter Driver) provide support as well.
1279#
1280# The targ driver provides target mode support as a Processor type device.
1281# It exists to give the minimal context necessary to respond to Inquiry
1282# commands. There is a sample user application that shows how the rest
1283# of the command support might be done in /usr/share/examples/scsi_target.
1284#
1285# The targbh driver provides target mode support and exists to respond
1286# to incoming commands that do not otherwise have a logical unit assigned
1287# to them.

1620# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1621# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1622# The DPT controllers are commonly re-licensed under other brand-names -
1623# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1624# Compaq are actually DPT controllers.
1625#
1626# See src/sys/dev/dpt for debugging and other subtle options.
1627# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1628# instruments are enabled. The tools in
1629# /usr/sbin/dpt_* assume these to be enabled.
1630# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1631# If you want the driver to handle timeouts, enable
1632# this option. If your system is very busy, this
1633# option will create more trouble than solve.
1634# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1635# wait when timing out with the above option.
1636# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1637# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1638# any interrupt that got lost. Seems to help in some
1639# DPT-firmware/Motherboard combinations. Minimal
1640# cost, great benefit.

2444# This also allows Bt878/879 chips to work on old OPTi (<1997) chipset
