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.
14#
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.
50#

53#
54# The `makeoptions' parameter allows variables to be passed to the
55# generated Makefile in the build area.
56#
57# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
58# after most other flags.  Here we use it to inhibit use of non-optimal
59# gcc built-in functions (e.g., memcmp).
60#
61# DEBUG happens to be magic.
62# The following is equivalent to 'config -g KERNELNAME' and creates
63# 'kernel.debug' compiled with -g debugging as well as a normal
64# 'kernel'.  Use 'make install.debug' to install the debug kernel
65# but that isn't normally necessary as the debug symbols are not loaded
66# by the kernel and are not useful there anyway.
67#
68# KERNEL can be overridden so that you can change the default name of your
69# kernel.
70#
71# MODULES_OVERRIDE can be used to limit modules built to a specific list.

81# FreeBSD processes are subject to certain limits to their consumption
82# of system resources.  See getrlimit(2) for more details.  Each
83# resource limit has two values, a "soft" limit and a "hard" limit.
84# The soft limits can be modified during normal system operation, but
85# the hard limits are set at boot time.  Their default values are
86# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
87#
88# 1.  Set the values at kernel build time.  The options below are one
89#     way to allow that limit to grow to 1GB.  They can be increased
90#     further by changing the parameters:
91#
92# 2.  In /boot/loader.conf, set the tunables kern.maxswzone,
93#     kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
94#     kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
95#
96# The options in /boot/loader.conf override anything in the kernel
97# configuration file.  See the function init_param1 in
98# sys/kern/subr_param.c for more details.

174# Scheduler options:
175#
176# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory.  These options
177# select which scheduler is compiled in.
178#
179# SCHED_4BSD is the historical, proven, BSD scheduler.  It has a global run
180# queue and no CPU affinity which makes it suboptimal for SMP.  It has very
181# good interactivity and priority selection.
182#
183# SCHED_ULE provides significant performance advantages over 4BSD on many
184# workloads on SMP machines.  It supports cpu-affinity, per-cpu runqueues
185# and scheduler locks.  It also has a stronger notion of interactivity
186# which leads to better responsiveness even on uniprocessor machines.  This
187# will eventually become the default scheduler.
188#
189# SCHED_STATS is a debugging option which keeps some stats in the sysctl
190# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions.

248#	  WARNING! Only tested on amd64 and i386.
249# FULL_PREEMPTION instructs the kernel to preempt non-realtime kernel
250#	  threads.  Its sole use is to expose race conditions and other

547# SCTP is a NEW transport protocol defined by

549# soon to have a new base RFC and many many more
550# extensions. This release supports all the extensions
551# including many drafts (most about to become RFC's).
552# It is the premeier SCTP implementation in the NET
553# and is quite well tested.
554#
555# Note YOU MUST have both INET and INET6 defined.
556# you don't have to enable V6, but SCTP is
557# dual stacked and so far we have not teased apart
558# the V6 and V4.. since an association can span
559# both a V6 and V4 address at the SAME time :-)

562# There are bunches of options:
563# this one turns on all sorts of
564# nastly printing that you can
565# do. Its all controled by a
566# bit mask (settable by socket opt and
567# by sysctl). Including will not cause
568# logging until you set the bits.. but it
569# can be quite verbose.. so without this
570# option we don't do any of the tests for
571# bits and prints.. which makes the code run
572# faster.. if you are not debugging don't use.
573options SCTP_DEBUG
574#
575# This option turns off the CRC32c checksum. Basically
576# You will not be able to talk to anyone else that
577# has not done this. Its more for expermentation to
578# see how much CPU the CRC32c really takes. Most new
579# cards for TCP support checksum offload.. so this
580# option gives you a "view" into what SCTP would be
581# like with such an offload (which only exists in
582# high in iSCSI boards so far). With the new
583# splitting 8's algorithm its not as bad as it used

701# Network interfaces:
702#  The `loop' device is MANDATORY when networking is enabled.
703#  The `ether' device provides generic code to handle
704#  Ethernets; it is MANDATORY when an Ethernet device driver is
705#  configured or token-ring is enabled.
706#  The `vlan' device implements the VLAN tagging of Ethernet frames
707#  according to IEEE 802.1Q.  It requires `device miibus'.
708#  The `wlan' device provides generic code to support 802.11
709#  drivers, including host AP mode; it is MANDATORY for the wi,
710#  and ath drivers and will eventually be required by all 802.11 drivers.
711#  The `wlan_wep', `wlan_tkip', and `wlan_ccmp' devices provide
712#  support for WEP, TKIP, and AES-CCMP crypto protocols optionally
713#  used with 802.11 devices that depend on the `wlan' module.
714#  The `wlan_xauth' device provides support for external (i.e. user-mode)
715#  authenticators for use with 802.11 drivers that use the `wlan'
716#  module and support 802.1x and/or WPA security protocols.
717#  The `wlan_acl' device provides a MAC-based access control mechanism
718#  for use with 802.11 drivers operating in ap mode and using the
719#  `wlan' module.
720#  The `fddi' device provides generic code to support FDDI.
721#  The `arcnet' device provides generic code to support Arcnet.
722#  The `sppp' device serves a similar role for certain types
723#  of synchronous PPP links (like `cx', `ar').
724#  The `sl' device implements the Serial Line IP (SLIP) service.
725#  The `ppp' device implements the Point-to-Point Protocol.
726#  The `bpf' device enables the Berkeley Packet Filter.  Be
727#  aware of the legal and administrative consequences of enabling this
728#  option.  The number of devices determines the maximum number of
729#  simultaneous BPF clients programs runnable.  DHCP requires bpf.
730#  The `disc' device implements a minimal network interface,
731#  which throws away all packets sent and never receives any.  It is
732#  included for testing and benchmarking purposes.
733#  The `edsc' device implements a minimal Ethernet interface,
734#  which discards all packets sent and receives none.
735#  The `tap' device is a pty-like virtual Ethernet interface
736#  The `tun' device implements (user-)ppp and nos-tun
737#  The `gif' device implements IPv6 over IP4 tunneling,
738#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
739#  IPv6 over IPv6 tunneling.
740#  The `gre' device implements two types of IP4 over IP4 tunneling:
741#  GRE and MOBILE, as specified in the RFC1701 and RFC2004.
742#  The XBONEHACK option allows the same pair of addresses to be configured on
743#  multiple gif interfaces.
744#  The `faith' device captures packets sent to it and diverts them
745#  to the IPv4/IPv6 translation daemon.
746#  The `stf' device implements 6to4 encapsulation.
747#  The `ef' device provides support for multiple ethernet frame types
748#  specified via ETHER_* options. See ef(4) for details.
749#
750# The pf packet filter consists of three devices:
751#  The `pf' device provides /dev/pf and the firewall code itself.
752#  The `pflog' device provides the pflog0 interface which logs packets.
753#  The `pfsync' device provides the pfsync0 interface used for
754#   synchronization of firewall state tables (over the net).
755#
756# The PPP_BSDCOMP option enables support for compress(1) style entire
757# packet compression, the PPP_DEFLATE is for zlib/gzip style compression.
758# PPP_FILTER enables code for filtering the ppp data stream and selecting
759# events for resetting the demand dial activity timer - requires bpf.

815# logged packets to the system logger.  IPFIREWALL_VERBOSE_LIMIT
816# limits the number of times a matching entry can be logged.

818# WARNING:  IPFIREWALL defaults to a policy of "deny ip from any to any"
819# and if you do not add other rules during startup to allow access,

825# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to

830# means that you won't get stuck if the kernel and /sbin/ipfw binary get
831# out of sync.

833# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''.  It
834# depends on IPFIREWALL if compiled into the kernel.

1136# SCSI DEVICES
1137
1138# SCSI DEVICE CONFIGURATION
1139
1140# The SCSI subsystem consists of the `base' SCSI code, a number of
1141# high-level SCSI device `type' drivers, and the low-level host-adapter
1142# device drivers.  The host adapters are listed in the ISA and PCI
1143# device configuration sections below.
1144#
1145# It is possible to wire down your SCSI devices so that a given bus,
1146# target, and LUN always come on line as the same device unit.  In
1147# earlier versions the unit numbers were assigned in the order that
1148# the devices were probed on the SCSI bus.  This means that if you
1149# removed a disk drive, you may have had to rewrite your /etc/fstab
1150# file, and also that you had to be careful when adding a new disk
1151# as it may have been probed earlier and moved your device configuration
1152# around.  (See also option GEOM_VOL for a different solution to this
1153# problem.)
1154
1155# This old behavior is maintained as the default behavior.  The unit
1156# assignment begins with the first non-wired down unit for a device
1157# type.  For example, if you wire a disk as "da3" then the first
1158# non-wired disk will be assigned da4.
1159
1160# The syntax for wiring down devices is:

1195#
1196# The pt driver drives SCSI Processor devices.
1197#
1198# The sg driver provides a passthrough API that is compatible with the
1199# Linux SG driver.  It will work in conjunction with the COMPAT_LINUX
1200# option to run linux SG apps.  It can also stand on its own and provide
1201# source level API compatiblity for porting apps to FreeBSD.
1202#
1203# Target Mode support is provided here but also requires that a SIM
1204# (SCSI Host Adapter Driver) provide support as well.
1205#
1206# The targ driver provides target mode support as a Processor type device.
1207# It exists to give the minimal context necessary to respond to Inquiry
1208# commands. There is a sample user application that shows how the rest
1209# of the command support might be done in /usr/share/examples/scsi_target.
1210#
1211# The targbh driver provides target mode support and exists to respond
1212# to incoming commands that do not otherwise have a logical unit assigned
1213# to them.

1551# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and

1553#
1554# See src/sys/dev/dpt for debugging and other subtle options.
1555#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1556#                           instruments are enabled.  The tools in

1558#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1559#                           If you ant the driver to handle timeouts, enable
1560#                           this option.  If your system is very busy, this
1561#                           option will create more trouble than solve.
