3# NOTES -- Lines that can be cut/pasted into kernel and hints configs.
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.
11#
12# Please use ``make LINT'' to create an old-style LINT file if you want to
13# do kernel test-builds.

15# This file contains machine independent kernel configuration notes. For
16# machine dependent notes, look in /sys/<arch>/conf/NOTES.

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#
38
39#
40# This is the ``identification'' of the kernel. Usually this should
41# be the same as the name of your kernel.

46# The `maxusers' parameter controls the static sizing of a number of
47# internal system tables by a formula defined in subr_param.c.
48# Omitting this parameter or setting it to 0 will cause the system to
49# auto-size based on physical memory.

56# Use the following to compile in values accessible to the kernel
57# through getenv() (or kenv(1) in userland). The format of the file
58# is 'variable=value', see kenv(1)
59#
60#env "LINT.env"
61
62#
63# The `makeoptions' parameter allows variables to be passed to the
64# generated Makefile in the build area.
65#
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
73# 'kernel'. Use 'make install.debug' to install the debug kernel
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#
77# KERNEL can be overridden so that you can change the default name of your
78# kernel.

80# MODULES_OVERRIDE can be used to limit modules built to a specific list.

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
99# further by changing the parameters:
100#
101# 2. In /boot/loader.conf, set the tunables kern.maxswzone,
102# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
103# kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
104#
105# The options in /boot/loader.conf override anything in the kernel

186# Scheduler options:
187#
188# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory. These options
189# select which scheduler is compiled in.
190#
191# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
192# queue and no CPU affinity which makes it suboptimal for SMP. It has very
193# good interactivity and priority selection.
194#
195# SCHED_ULE provides significant performance advantages over 4BSD on many
196# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues
197# and scheduler locks. It also has a stronger notion of interactivity
198# which leads to better responsiveness even on uniprocessor machines. This
199# is the default scheduler.
200#
201# SCHED_STATS is a debugging option which keeps some stats in the sysctl
202# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions.

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

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

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

1207# SCSI DEVICES
1208
1209# SCSI DEVICE CONFIGURATION
1210
1211# The SCSI subsystem consists of the `base' SCSI code, a number of
1212# high-level SCSI device `type' drivers, and the low-level host-adapter
1213# device drivers. The host adapters are listed in the ISA and PCI
1214# device configuration sections below.
1215#
1216# It is possible to wire down your SCSI devices so that a given bus,
1217# target, and LUN always come on line as the same device unit. In
1218# earlier versions the unit numbers were assigned in the order that
1219# the devices were probed on the SCSI bus. This means that if you
1220# removed a disk drive, you may have had to rewrite your /etc/fstab
1221# file, and also that you had to be careful when adding a new disk
1222# as it may have been probed earlier and moved your device configuration
1223# around. (See also option GEOM_VOL for a different solution to this
1224# problem.)
1225
1226# This old behavior is maintained as the default behavior. The unit
1227# assignment begins with the first non-wired down unit for a device
1228# type. For example, if you wire a disk as "da3" then the first
1229# non-wired disk will be assigned da4.
1230
1231# The syntax for wiring down devices is:

1266#
1267# The pt driver drives SCSI Processor devices.
1268#
1269# The sg driver provides a passthrough API that is compatible with the
1270# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1271# option to run linux SG apps. It can also stand on its own and provide
1272# source level API compatibility for porting apps to FreeBSD.
1273#
1274# Target Mode support is provided here but also requires that a SIM
1275# (SCSI Host Adapter Driver) provide support as well.
1276#
1277# The targ driver provides target mode support as a Processor type device.
1278# It exists to give the minimal context necessary to respond to Inquiry
1279# commands. There is a sample user application that shows how the rest
1280# of the command support might be done in /usr/share/examples/scsi_target.
1281#
1282# The targbh driver provides target mode support and exists to respond
1283# to incoming commands that do not otherwise have a logical unit assigned
1284# to them.

1617# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1618# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1619# The DPT controllers are commonly re-licensed under other brand-names -
1620# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1621# Compaq are actually DPT controllers.
1622#
1623# See src/sys/dev/dpt for debugging and other subtle options.
1624# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1625# instruments are enabled. The tools in
1626# /usr/sbin/dpt_* assume these to be enabled.
1627# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1628# If you want the driver to handle timeouts, enable
1629# this option. If your system is very busy, this
1630# option will create more trouble than solve.
1631# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1632# wait when timing out with the above option.
1633# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1634# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1635# any interrupt that got lost. Seems to help in some
1636# DPT-firmware/Motherboard combinations. Minimal
1637# cost, great benefit.
1638# DPT_RESET_HBA Make "reset" actually reset the controller
1639# instead of fudging it. Only enable this if you

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#

39#
40# This is the ``identification'' of the kernel. Usually this should
41# be the same as the name of your kernel.

46# The `maxusers' parameter controls the static sizing of a number of
47# internal system tables by a formula defined in subr_param.c.
48# Omitting this parameter or setting it to 0 will cause the system to
49# auto-size based on physical memory.

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
73# 'kernel'. Use 'make install.debug' to install the debug kernel
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#
77# KERNEL can be overridden so that you can change the default name of your
78# kernel.

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
99# further by changing the parameters:

101# 2. In /boot/loader.conf, set the tunables kern.maxswzone,
102# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,

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

602options SCTP
603# There are bunches of options:
604# this one turns on all sorts of
605# nastily printing that you can
606# do. It's all controlled by a
607# bit mask (settable by socket opt and
608# by sysctl). Including will not cause
609# logging until you set the bits.. but it
610# can be quite verbose.. so without this
611# option we don't do any of the tests for
612# bits and prints.. which makes the code run
613# faster.. if you are not debugging don't use.
614options SCTP_DEBUG
615#
616# This option turns off the CRC32c checksum. Basically,
617# you will not be able to talk to anyone else who
618# has not done this. Its more for experimentation to
619# see how much CPU the CRC32c really takes. Most new
620# cards for TCP support checksum offload.. so this
621# option gives you a "view" into what SCTP would be
622# like with such an offload (which only exists in
623# high in iSCSI boards so far). With the new
624# splitting 8's algorithm its not as bad as it used

1207# SCSI DEVICES
1208
1209# SCSI DEVICE CONFIGURATION
1210
1211# The SCSI subsystem consists of the `base' SCSI code, a number of
1212# high-level SCSI device `type' drivers, and the low-level host-adapter
1213# device drivers. The host adapters are listed in the ISA and PCI
1214# device configuration sections below.
1215#
1216# It is possible to wire down your SCSI devices so that a given bus,
1217# target, and LUN always come on line as the same device unit. In
1218# earlier versions the unit numbers were assigned in the order that
1219# the devices were probed on the SCSI bus. This means that if you
1220# removed a disk drive, you may have had to rewrite your /etc/fstab
1221# file, and also that you had to be careful when adding a new disk
1222# as it may have been probed earlier and moved your device configuration
1223# around. (See also option GEOM_VOL for a different solution to this
1224# problem.)
1225
1226# This old behavior is maintained as the default behavior. The unit
1227# assignment begins with the first non-wired down unit for a device
1228# type. For example, if you wire a disk as "da3" then the first
1229# non-wired disk will be assigned da4.
1230
1231# The syntax for wiring down devices is:

1266#
1267# The pt driver drives SCSI Processor devices.
1268#
1269# The sg driver provides a passthrough API that is compatible with the
1270# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1271# option to run linux SG apps. It can also stand on its own and provide
1272# source level API compatibility for porting apps to FreeBSD.
1273#
1274# Target Mode support is provided here but also requires that a SIM
1275# (SCSI Host Adapter Driver) provide support as well.
1276#
1277# The targ driver provides target mode support as a Processor type device.
1278# It exists to give the minimal context necessary to respond to Inquiry
1279# commands. There is a sample user application that shows how the rest
1280# of the command support might be done in /usr/share/examples/scsi_target.
1281#
1282# The targbh driver provides target mode support and exists to respond
1283# to incoming commands that do not otherwise have a logical unit assigned
1284# to them.

1617# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1618# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1619# The DPT controllers are commonly re-licensed under other brand-names -
1620# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1621# Compaq are actually DPT controllers.
1622#
1623# See src/sys/dev/dpt for debugging and other subtle options.
1624# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1625# instruments are enabled. The tools in
1626# /usr/sbin/dpt_* assume these to be enabled.
1627# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1628# If you want the driver to handle timeouts, enable
1629# this option. If your system is very busy, this
1630# option will create more trouble than solve.
1631# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1632# wait when timing out with the above option.
1633# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1634# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1635# any interrupt that got lost. Seems to help in some
1636# DPT-firmware/Motherboard combinations. Minimal
1637# cost, great benefit.
1638# DPT_RESET_HBA Make "reset" actually reset the controller
1639# instead of fudging it. Only enable this if you
1640# are 100% certain you need it.
