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#

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#

52
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.

170# Scheduler options:
171#
172# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory. These options
173# select which scheduler is compiled in.
174#
175# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
176# queue and no CPU affinity which makes it suboptimal for SMP. It has very
177# good interactivity and priority selection.
178#
179# SCHED_ULE provides significant performance advantages over 4BSD on many
180# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues
181# and scheduler locks. It also has a stronger notion of interactivity
182# which leads to better responsiveness even on uniprocessor machines. This
183# will eventually become the default scheduler.

195
196# ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin
197# if the thread that currently owns the mutex is executing on another

206options NO_ADAPTIVE_RWLOCKS
207
208# ADAPTIVE_GIANT causes the Giant lock to also be made adaptive when

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

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

811# WARNING: IPFIREWALL defaults to a policy of "deny ip from any to any"

814# in /etc/rc.conf when first enabling this feature, then refining the

821# if you are using it as an as-needed filter for specific problems as
822# they arise, then this may be for you. Changing the default to 'allow'
823# means that you won't get stuck if the kernel and /sbin/ipfw binary get
824# out of sync.
825#
826# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''. It
827# depends on IPFIREWALL if compiled into the kernel.
828#
829# IPFIREWALL_FORWARD enables changing of the packet destination either
830# to do some sort of policy routing or transparent proxying. Used by
831# ``ipfw forward''. All redirections apply to locally generated
832# packets too. Because of this great care is required when
833# crafting the ruleset.

1129# SCSI DEVICES
1130
1131# SCSI DEVICE CONFIGURATION
1132
1133# The SCSI subsystem consists of the `base' SCSI code, a number of
1134# high-level SCSI device `type' drivers, and the low-level host-adapter
1135# device drivers. The host adapters are listed in the ISA and PCI
1136# device configuration sections below.
1137#
1138# It is possible to wire down your SCSI devices so that a given bus,
1139# target, and LUN always come on line as the same device unit. In
1140# earlier versions the unit numbers were assigned in the order that
1141# the devices were probed on the SCSI bus. This means that if you
1142# removed a disk drive, you may have had to rewrite your /etc/fstab
1143# file, and also that you had to be careful when adding a new disk
1144# as it may have been probed earlier and moved your device configuration
1145# around. (See also option GEOM_VOL for a different solution to this
1146# problem.)
1147
1148# This old behavior is maintained as the default behavior. The unit
1149# assignment begins with the first non-wired down unit for a device
1150# type. For example, if you wire a disk as "da3" then the first
1151# non-wired disk will be assigned da4.
1152
1153# The syntax for wiring down devices is:

1188#
1189# The pt driver drives SCSI Processor devices.
1190#
1191# The sg driver provides a passthrough API that is compatible with the
1192# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
1193# option to run linux SG apps. It can also stand on its own and provide
1194# source level API compatiblity for porting apps to FreeBSD.
1195#
1196# Target Mode support is provided here but also requires that a SIM
1197# (SCSI Host Adapter Driver) provide support as well.
1198#
1199# The targ driver provides target mode support as a Processor type device.
1200# It exists to give the minimal context necessary to respond to Inquiry
1201# commands. There is a sample user application that shows how the rest
1202# of the command support might be done in /usr/share/examples/scsi_target.
1203#
1204# The targbh driver provides target mode support and exists to respond
1205# to incoming commands that do not otherwise have a logical unit assigned
1206# to them.
