2# 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. 17# 18 19# 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 manpages. 31# 32# A space followed by a tab separates 'option' 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 'option' 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. 42# 43ident LINT 44 45# 46# The `maxusers' parameter controls the static sizing of a number of 47# internal system tables by a formula defined in subr_param.c. Setting 48# maxusers to 0 will cause the system to auto-size based on physical 49# memory. 50# 51maxusers 10 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 builtin 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. 72# 73makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 74#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 75#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 76# Only build Linux API modules and plus those parts of the sound system I need. 77#makeoptions MODULES_OVERRIDE="linux sound/snd sound/pcm sound/driver/maestro3" 78makeoptions DESTDIR=/tmp 79 80 81# 82# Certain applications can grow to be larger than the 512M limit 83# that FreeBSD initially imposes.

MAXDSIZ is the maximum that the 86# limit can be set to, and the DFLDSIZ is the default value for 87# the limit. MAXSSIZ is the maximum that the stack limit can be 88# set to.

To be more 267# SMP-friendly, KTRACE uses a worker thread to process most trace events 268# asynchronously to the thread generating the event. This requires a 269# pre-allocated store of objects representing trace events. The 270# KTRACE_REQUEST_POOL option specifies the initial size of this store. 271# The size of the pool can be adjusted both at boottime and runtime via 272# the kern.ktrace_request_pool tunable and sysctl. 273# 274options KTRACE #kernel tracing 275options KTRACE_REQUEST_POOL=101 276 277# 278# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 279# has no userland interface aside from a few sysctl's. It is enabled with 280# the KTR option. KTR_ENTRIES defines the number of entries in the circular 281# trace buffer. KTR_COMPILE defines the mask of events to compile into the 282# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 283# initial value of the ktr_mask variable which determines at runtime what 284# events to trace. KTR_CPUMASK determines which CPU's log events, with 285# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 286# to the console by default. This functionality can be toggled via the 287# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 288# 289options KTR 290options KTR_ENTRIES=1024 291options KTR_COMPILE=(KTR_INTR|KTR_PROC) 292options KTR_MASK=KTR_INTR 293options KTR_CPUMASK=0x3 294options KTR_VERBOSE 295 296# 297# The INVARIANTS option is used in a number of source files to enable 298# extra sanity checking of internal structures.

It is a prerequisite for 308# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 309# called. The intent is that you can set 'INVARIANTS' for single 310# source files (by changing the source file or specifying it on the 311# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 312# wish to build a kernel module with 'INVARIANTS', then adding 313# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 314# infrastructure without the added overhead. 315# 316options INVARIANT_SUPPORT 317 318# 319# The DIAGNOSTIC option is used to enable extra debugging information 320# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 850# device configuration sections below. 851# 852# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 853# that a given bus, target, and LUN always come on line as the same 854# device unit. In earlier versions the unit numbers were assigned 855# in the order that the devices were probed on the SCSI bus. This 856# means that if you removed a disk drive, you may have had to rewrite 857# your /etc/fstab file, and also that you had to be careful when adding 858# a new disk as it may have been probed earlier and moved your device 859# configuration around. 860 861# This old behavior is maintained as the default behavior. The unit 862# assignment begins with the first non-wired down unit for a device 863# type. For example, if you wire a disk as "da3" then the first 864# non-wired disk will be assigned da4. 865 866# The syntax for wiring down devices is: 867 868hint.scbus.0.at="ahc0" 869hint.scbus.1.at="ahc1" 870hint.scbus.1.bus="0" 871hint.scbus.3.at="ahc2" 872hint.scbus.3.bus="0" 873hint.scbus.2.at="ahc2" 874hint.scbus.2.bus="1" 875hint.da.0.at="scbus0" 876hint.da.0.target="0" 877hint.da.0.unit="0" 878hint.da.1.at="scbus3" 879hint.da.1.target="1" 880hint.da.2.at="scbus2" 881hint.da.2.target="3" 882hint.sa.1.at="scbus1" 883hint.sa.1.target="6" 884 885# "units" (SCSI logical unit number) that are not specified are 886# treated as if specified as LUN 0. 887 888# All SCSI devices allocate as many units as are required. 889 890# The ch driver drives SCSI Media Changer ("jukebox") devices. 891# 892# The da driver drives SCSI Direct Access ("disk") and Optical Media 893# ("WORM") devices. 894# 895# The sa driver drives SCSI Sequential Access ("tape") devices. 896# 897# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 898# 899# The ses driver drives SCSI Envinronment Services ("ses") and 900# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 901# 902# The pt driver drives SCSI Processor devices. 903# 904# 905# Target Mode support is provided here but also requires that a SIM 906# (SCSI Host Adapter Driver) provide support as well. 907# 908# The targ driver provides target mode support as a Processor type device. 909# It exists to give the minimal context necessary to respond to Inquiry 910# commands.

The host adapters are listed in the ISA and PCI 850# device configuration sections below. 851# 852# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 853# that a given bus, target, and LUN always come on line as the same 854# device unit. In earlier versions the unit numbers were assigned 855# in the order that the devices were probed on the SCSI bus. This 856# means that if you removed a disk drive, you may have had to rewrite 857# your /etc/fstab file, and also that you had to be careful when adding 858# a new disk as it may have been probed earlier and moved your device 859# configuration around. 860 861# This old behavior is maintained as the default behavior. The unit 862# assignment begins with the first non-wired down unit for a device 863# type. For example, if you wire a disk as "da3" then the first 864# non-wired disk will be assigned da4. 865 866# The syntax for wiring down devices is: 867 868hint.scbus.0.at="ahc0" 869hint.scbus.1.at="ahc1" 870hint.scbus.1.bus="0" 871hint.scbus.3.at="ahc2" 872hint.scbus.3.bus="0" 873hint.scbus.2.at="ahc2" 874hint.scbus.2.bus="1" 875hint.da.0.at="scbus0" 876hint.da.0.target="0" 877hint.da.0.unit="0" 878hint.da.1.at="scbus3" 879hint.da.1.target="1" 880hint.da.2.at="scbus2" 881hint.da.2.target="3" 882hint.sa.1.at="scbus1" 883hint.sa.1.target="6" 884 885# "units" (SCSI logical unit number) that are not specified are 886# treated as if specified as LUN 0. 887 888# All SCSI devices allocate as many units as are required. 889 890# The ch driver drives SCSI Media Changer ("jukebox") devices. 891# 892# The da driver drives SCSI Direct Access ("disk") and Optical Media 893# ("WORM") devices. 894# 895# The sa driver drives SCSI Sequential Access ("tape") devices. 896# 897# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 898# 899# The ses driver drives SCSI Envinronment Services ("ses") and 900# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 901# 902# The pt driver drives SCSI Processor devices. 903# 904# 905# Target Mode support is provided here but also requires that a SIM 906# (SCSI Host Adapter Driver) provide support as well. 907# 908# The targ driver provides target mode support as a Processor type device. 909# It exists to give the minimal context necessary to respond to Inquiry 910# commands.
