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" 78 79# 80# Certain applications can grow to be larger than the 512M limit 81# that FreeBSD initially imposes. Below are some options to 82# allow that limit to grow to 1GB, and can be increased further 83# with changing the parameters. MAXDSIZ is the maximum that the 84# limit can be set to, and the DFLDSIZ is the default value for 85# the limit. MAXSSIZ is the maximum that the stack limit can be 86# set to. You might want to set the default lower than the max, 87# and explicitly set the maximum with a shell command for processes 88# that regularly exceed the limit like INND. 89# 90options MAXDSIZ="(1024UL*1024*1024)" 91options MAXSSIZ="(128UL*1024*1024)" 92options DFLDSIZ="(1024UL*1024*1024)" 93 94# 95# BLKDEV_IOSIZE sets the default block size used in user block 96# device I/O.

It's non- 229# standard and you're on your own if you enable it. See also the 230# "remotechat" variables in the FreeBSD specific version of gdb. 231# 232options GDB_REMOTE_CHAT 233 234# 235# KTRACE enables the system-call tracing facility ktrace(2). To be more 236# SMP-friendly, KTRACE uses a worker thread to process most trace events 237# asynchronously to the thread generating the event. This requires a 238# pre-allocated store of objects representing trace events. The 239# KTRACE_REQUEST_POOL option specifies the initial size of this store. 240# The size of the pool can be adjusted both at boottime and runtime via 241# the kern.ktrace_request_pool tunable and sysctl. 242# 243options KTRACE #kernel tracing 244options KTRACE_REQUEST_POOL=101 245 246# 247# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 248# has no userland interface aside from a few sysctl's. It is enabled with 249# the KTR option. KTR_ENTRIES defines the number of entries in the circular 250# trace buffer. KTR_COMPILE defines the mask of events to compile into the 251# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 252# initial value of the ktr_mask variable which determines at runtime what 253# events to trace. KTR_CPUMASK determines which CPU's log events, with 254# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 255# to the console by default. This functionality can be toggled via the 256# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 257# 258options KTR 259options KTR_ENTRIES=1024 260options KTR_COMPILE="(KTR_INTR|KTR_PROC)" 261options KTR_MASK=KTR_INTR 262options KTR_CPUMASK=0x3 263options KTR_VERBOSE 264 265# 266# The INVARIANTS option is used in a number of source files to enable 267# extra sanity checking of internal structures. This support is not 268# enabled by default because of the extra time it would take to check 269# for these conditions, which can only occur as a result of 270# programming errors. 271# 272options INVARIANTS 273 274# 275# The INVARIANT_SUPPORT option makes us compile in support for 276# verifying some of the internal structures. It is a prerequisite for 277# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 278# called. The intent is that you can set 'INVARIANTS' for single 279# source files (by changing the source file or specifying it on the 280# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 281# wish to build a kernel module with 'INVARIANTS', then adding 282# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 283# infrastructure without the added overhead. 284# 285options INVARIANT_SUPPORT 286 287# 288# The DIAGNOSTIC option is used to enable extra debugging information 289# from some parts of the kernel. As this makes everything more noisy, 290# it is disabled by default. 291# 292options DIAGNOSTIC 293 294# 295# REGRESSION causes optional kernel interfaces necessary only for regression 296# testing to be enabled. These interfaces may consitute security risks 297# when enabled, as they permit processes to easily modify aspects of the 298# run-time environment to reproduce unlikely or unusual (possibly normally 299# impossible) scenarios. 300# 301options REGRESSION 302 303# 304# RESTARTABLE_PANICS allows one to continue from a panic as if it were 305# a call to the debugger via the Debugger() function instead. It is only 306# useful if a kernel debugger is present. To restart from a panic, reset 307# the panicstr variable to NULL and continue execution. This option is 308# for development use only and should NOT be used in production systems 309# to "workaround" a panic. 310# 311#options RESTARTABLE_PANICS 312 313# 314# This option let some drivers co-exist that can't co-exist in a running 315# system.

The host adapters are listed in the ISA and PCI 794# device configuration sections below. 795# 796# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 797# that a given bus, target, and LUN always come on line as the same 798# device unit. In earlier versions the unit numbers were assigned 799# in the order that the devices were probed on the SCSI bus. This 800# means that if you removed a disk drive, you may have had to rewrite 801# your /etc/fstab file, and also that you had to be careful when adding 802# a new disk as it may have been probed earlier and moved your device 803# configuration around. 804 805# This old behavior is maintained as the default behavior. The unit 806# assignment begins with the first non-wired down unit for a device 807# type. For example, if you wire a disk as "da3" then the first 808# non-wired disk will be assigned da4. 809 810# The syntax for wiring down devices is: 811 812hint.scbus.0.at="ahc0" 813hint.scbus.1.at="ahc1" 814hint.scbus.1.bus="0" 815hint.scbus.3.at="ahc2" 816hint.scbus.3.bus="0" 817hint.scbus.2.at="ahc2" 818hint.scbus.2.bus="1" 819hint.da.0.at="scbus0" 820hint.da.0.target="0" 821hint.da.0.unit="0" 822hint.da.1.at="scbus3" 823hint.da.1.target="1" 824hint.da.2.at="scbus2" 825hint.da.2.target="3" 826hint.sa.1.at="scbus1" 827hint.sa.1.target="6" 828 829# "units" (SCSI logical unit number) that are not specified are 830# treated as if specified as LUN 0. 831 832# All SCSI devices allocate as many units as are required. 833 834# The ch driver drives SCSI Media Changer ("jukebox") devices. 835# 836# The da driver drives SCSI Direct Access ("disk") and Optical Media 837# ("WORM") devices. 838# 839# The sa driver drives SCSI Sequential Access ("tape") devices. 840# 841# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 842# 843# The ses driver drives SCSI Envinronment Services ("ses") and 844# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 845# 846# The pt driver drives SCSI Processor devices. 847# 848# 849# Target Mode support is provided here but also requires that a SIM 850# (SCSI Host Adapter Driver) provide support as well. 851# 852# The targ driver provides target mode support as a Processor type device. 853# It exists to give the minimal context necessary to respond to Inquiry 854# commands.
