NOTES revision 96755
1# 2# NOTES -- Lines that can be cut/pasted into kernel and hints configs. 3# 4# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers', 5# 'makeoptions', 'hints' etc go into the kernel configuration that you 6# run config(8) with. 7# 8# Lines that begin with 'hints.' are NOT for config(8), they go into your 9# hints file. See /boot/device.hints and/or the 'hints' config(8) directive. 10# 11# Please use ``make LINT'' to create an old-style LINT file if you want to 12# do kernel test-builds. 13# 14# This file contains machine independent kernel configuration notes. For 15# machine dependent notes, look in /sys/<arch>/conf/NOTES. 16# 17# $FreeBSD: head/sys/conf/NOTES 96755 2002-05-16 21:28:32Z trhodes $ 18# 19 20# 21# This is the ``identification'' of the kernel. Usually this should 22# be the same as the name of your kernel. 23# 24ident LINT 25 26# 27# The `maxusers' parameter controls the static sizing of a number of 28# internal system tables by a formula defined in subr_param.c. Setting 29# maxusers to 0 will cause the system to auto-size based on physical 30# memory. 31# 32maxusers 10 33 34# 35# We want LINT to cover profiling as well 36profile 2 37 38# 39# The `makeoptions' parameter allows variables to be passed to the 40# generated Makefile in the build area. 41# 42# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 43# after most other flags. Here we use it to inhibit use of non-optimal 44# gcc builtin functions (e.g., memcmp). 45# 46# DEBUG happens to be magic. 47# The following is equivalent to 'config -g KERNELNAME' and creates 48# 'kernel.debug' compiled with -g debugging as well as a normal 49# 'kernel'. Use 'make install.debug' to install the debug kernel 50# but that isn't normally necessary as the debug symbols are not loaded 51# by the kernel and are not useful there anyway. 52# 53# KERNEL can be overridden so that you can change the default name of your 54# kernel. 55# 56# MODULES_OVERRIDE can be used to limit modules built to a specific list. 57# 58makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 59#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 60#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 61# Only build Linux API modules and plus those parts of the sound system I need. 62#makeoptions MODULES_OVERRIDE="linux sound/snd sound/pcm sound/driver/maestro3" 63 64# 65# Certain applications can grow to be larger than the 512M limit 66# that FreeBSD initially imposes. Below are some options to 67# allow that limit to grow to 1GB, and can be increased further 68# with changing the parameters. MAXDSIZ is the maximum that the 69# limit can be set to, and the DFLDSIZ is the default value for 70# the limit. MAXSSIZ is the maximum that the stack limit can be 71# set to. You might want to set the default lower than the max, 72# and explicitly set the maximum with a shell command for processes 73# that regularly exceed the limit like INND. 74# 75options MAXDSIZ="(1024UL*1024*1024)" 76options MAXSSIZ="(128UL*1024*1024)" 77options DFLDSIZ="(1024UL*1024*1024)" 78 79# 80# BLKDEV_IOSIZE sets the default block size used in user block 81# device I/O.

It's non- 207# standard and you're on your own if you enable it. See also the 208# "remotechat" variables in the FreeBSD specific version of gdb. 209# 210options GDB_REMOTE_CHAT 211 212# 213# KTRACE enables the system-call tracing facility ktrace(2). 214# 215options KTRACE #kernel tracing 216 217# 218# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 219# has no userland interface aside from a few sysctl's. It is enabled with 220# the KTR option. KTR_ENTRIES defines the number of entries in the circular 221# trace buffer. KTR_COMPILE defines the mask of events to compile into the 222# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 223# initial value of the ktr_mask variable which determines at runtime what 224# events to trace. KTR_CPUMASK determines which CPU's log events, with 225# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 226# to the console by default. This functionality can be toggled via the 227# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 228# 229options KTR 230options KTR_ENTRIES=1024 231options KTR_COMPILE="(KTR_INTR|KTR_PROC)" 232options KTR_MASK=KTR_INTR 233options KTR_CPUMASK=0x3 234options KTR_VERBOSE 235 236# 237# The INVARIANTS option is used in a number of source files to enable 238# extra sanity checking of internal structures. This support is not 239# enabled by default because of the extra time it would take to check 240# for these conditions, which can only occur as a result of 241# programming errors. 242# 243options INVARIANTS 244 245# 246# The INVARIANT_SUPPORT option makes us compile in support for 247# verifying some of the internal structures. It is a prerequisite for 248# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 249# called. The intent is that you can set 'INVARIANTS' for single 250# source files (by changing the source file or specifying it on the 251# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 252# wish to build a kernel module with 'INVARIANTS', then adding 253# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 254# infrastructure without the added overhead. 255# 256options INVARIANT_SUPPORT 257 258# 259# The DIAGNOSTIC option is used to enable extra debugging information 260# from some parts of the kernel.

These interfaces may consitute security risks 268# when enabled, as they permit processes to easily modify aspects of the 269# run-time environment to reproduce unlikely or unusual (possibly normally 270# impossible) scenarios. 271# 272options REGRESSION 273 274# 275# RESTARTABLE_PANICS allows one to continue from a panic as if it were 276# a call to the debugger via the Debugger() function instead. It is only 277# useful if a kernel debugger is present. To restart from a panic, reset 278# the panicstr variable to NULL and continue execution. This option is 279# for development use only and should NOT be used in production systems 280# to "workaround" a panic. 281# 282#options RESTARTABLE_PANICS 283 284# 285# This option let some drivers co-exist that can't co-exist in a running 286# system.

The host adapters are listed in the ISA and PCI 732# device configuration sections below. 733# 734# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 735# that a given bus, target, and LUN always come on line as the same 736# device unit. In earlier versions the unit numbers were assigned 737# in the order that the devices were probed on the SCSI bus. This 738# means that if you removed a disk drive, you may have had to rewrite 739# your /etc/fstab file, and also that you had to be careful when adding 740# a new disk as it may have been probed earlier and moved your device 741# configuration around. 742 743# This old behavior is maintained as the default behavior. The unit 744# assignment begins with the first non-wired down unit for a device 745# type. For example, if you wire a disk as "da3" then the first 746# non-wired disk will be assigned da4. 747 748# The syntax for wiring down devices is: 749 750hint.scbus.0.at="ahc0" 751hint.scbus.1.at="ahc1" 752hint.scbus.1.bus="0" 753hint.scbus.3.at="ahc2" 754hint.scbus.3.bus="0" 755hint.scbus.2.at="ahc2" 756hint.scbus.2.bus="1" 757hint.da.0.at="scbus0" 758hint.da.0.target="0" 759hint.da.0.unit="0" 760hint.da.1.at="scbus3" 761hint.da.1.target="1" 762hint.da.2.at="scbus2" 763hint.da.2.target="3" 764hint.sa.1.at="scbus1" 765hint.sa.1.target="6" 766 767# "units" (SCSI logical unit number) that are not specified are 768# treated as if specified as LUN 0. 769 770# All SCSI devices allocate as many units as are required. 771 772# The ch driver drives SCSI Media Changer ("jukebox") devices. 773# 774# The da driver drives SCSI Direct Access ("disk") and Optical Media 775# ("WORM") devices. 776# 777# The sa driver drives SCSI Sequential Access ("tape") devices. 778# 779# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 780# 781# The ses driver drives SCSI Envinronment Services ("ses") and 782# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 783# 784# The pt driver drives SCSI Processor devices. 785# 786# 787# Target Mode support is provided here but also requires that a SIM 788# (SCSI Host Adapter Driver) provide support as well. 789# 790# The targ driver provides target mode support as a Processor type device. 791# It exists to give the minimal context necessary to respond to Inquiry 792# commands.
