NOTES revision 97983
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 97983 2002-06-07 02:04:09Z mdodd $ 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- 213# standard and you're on your own if you enable it. See also the 214# "remotechat" variables in the FreeBSD specific version of gdb. 215# 216options GDB_REMOTE_CHAT 217 218# 219# KTRACE enables the system-call tracing facility ktrace(2). 220# 221options KTRACE #kernel tracing 222 223# 224# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 225# has no userland interface aside from a few sysctl's. It is enabled with 226# the KTR option. KTR_ENTRIES defines the number of entries in the circular 227# trace buffer. KTR_COMPILE defines the mask of events to compile into the 228# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 229# initial value of the ktr_mask variable which determines at runtime what 230# events to trace. KTR_CPUMASK determines which CPU's log events, with 231# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 232# to the console by default. This functionality can be toggled via the 233# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 234# 235options KTR 236options KTR_ENTRIES=1024 237options KTR_COMPILE="(KTR_INTR|KTR_PROC)" 238options KTR_MASK=KTR_INTR 239options KTR_CPUMASK=0x3 240options KTR_VERBOSE 241 242# 243# The INVARIANTS option is used in a number of source files to enable 244# extra sanity checking of internal structures. This support is not 245# enabled by default because of the extra time it would take to check 246# for these conditions, which can only occur as a result of 247# programming errors. 248# 249options INVARIANTS 250 251# 252# The INVARIANT_SUPPORT option makes us compile in support for 253# verifying some of the internal structures. It is a prerequisite for 254# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 255# called. The intent is that you can set 'INVARIANTS' for single 256# source files (by changing the source file or specifying it on the 257# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 258# wish to build a kernel module with 'INVARIANTS', then adding 259# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 260# infrastructure without the added overhead. 261# 262options INVARIANT_SUPPORT 263 264# 265# The DIAGNOSTIC option is used to enable extra debugging information 266# from some parts of the kernel.

These interfaces may consitute security risks 274# when enabled, as they permit processes to easily modify aspects of the 275# run-time environment to reproduce unlikely or unusual (possibly normally 276# impossible) scenarios. 277# 278options REGRESSION 279 280# 281# RESTARTABLE_PANICS allows one to continue from a panic as if it were 282# a call to the debugger via the Debugger() function instead. It is only 283# useful if a kernel debugger is present. To restart from a panic, reset 284# the panicstr variable to NULL and continue execution. This option is 285# for development use only and should NOT be used in production systems 286# to "workaround" a panic. 287# 288#options RESTARTABLE_PANICS 289 290# 291# This option let some drivers co-exist that can't co-exist in a running 292# system.

The host adapters are listed in the ISA and PCI 735# device configuration sections below. 736# 737# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 738# that a given bus, target, and LUN always come on line as the same 739# device unit. In earlier versions the unit numbers were assigned 740# in the order that the devices were probed on the SCSI bus. This 741# means that if you removed a disk drive, you may have had to rewrite 742# your /etc/fstab file, and also that you had to be careful when adding 743# a new disk as it may have been probed earlier and moved your device 744# configuration around. 745 746# This old behavior is maintained as the default behavior. The unit 747# assignment begins with the first non-wired down unit for a device 748# type. For example, if you wire a disk as "da3" then the first 749# non-wired disk will be assigned da4. 750 751# The syntax for wiring down devices is: 752 753hint.scbus.0.at="ahc0" 754hint.scbus.1.at="ahc1" 755hint.scbus.1.bus="0" 756hint.scbus.3.at="ahc2" 757hint.scbus.3.bus="0" 758hint.scbus.2.at="ahc2" 759hint.scbus.2.bus="1" 760hint.da.0.at="scbus0" 761hint.da.0.target="0" 762hint.da.0.unit="0" 763hint.da.1.at="scbus3" 764hint.da.1.target="1" 765hint.da.2.at="scbus2" 766hint.da.2.target="3" 767hint.sa.1.at="scbus1" 768hint.sa.1.target="6" 769 770# "units" (SCSI logical unit number) that are not specified are 771# treated as if specified as LUN 0. 772 773# All SCSI devices allocate as many units as are required. 774 775# The ch driver drives SCSI Media Changer ("jukebox") devices. 776# 777# The da driver drives SCSI Direct Access ("disk") and Optical Media 778# ("WORM") devices. 779# 780# The sa driver drives SCSI Sequential Access ("tape") devices. 781# 782# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 783# 784# The ses driver drives SCSI Envinronment Services ("ses") and 785# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 786# 787# The pt driver drives SCSI Processor devices. 788# 789# 790# Target Mode support is provided here but also requires that a SIM 791# (SCSI Host Adapter Driver) provide support as well. 792# 793# The targ driver provides target mode support as a Processor type device. 794# It exists to give the minimal context necessary to respond to Inquiry 795# commands.
