1# $FreeBSD: head/sys/conf/NOTES 103214 2002-09-11 05:33:15Z njl $ 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# We want LINT to cover profiling as well 55profile 2 56 57# 58# The `makeoptions' parameter allows variables to be passed to the 59# generated Makefile in the build area. 60# 61# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 62# after most other flags. Here we use it to inhibit use of non-optimal 63# gcc builtin functions (e.g., memcmp). 64# 65# DEBUG happens to be magic. 66# The following is equivalent to 'config -g KERNELNAME' and creates 67# 'kernel.debug' compiled with -g debugging as well as a normal 68# 'kernel'. Use 'make install.debug' to install the debug kernel 69# but that isn't normally necessary as the debug symbols are not loaded 70# by the kernel and are not useful there anyway. 71# 72# KERNEL can be overridden so that you can change the default name of your 73# kernel. 74# 75# MODULES_OVERRIDE can be used to limit modules built to a specific list. 76# 77makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 78#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 79#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 80# Only build Linux API modules and plus those parts of the sound system I need. 81#makeoptions MODULES_OVERRIDE="linux sound/snd sound/pcm sound/driver/maestro3" 82 83# 84# Certain applications can grow to be larger than the 512M limit 85# that FreeBSD initially imposes. Below are some options to 86# allow that limit to grow to 1GB, and can be increased further 87# with changing the parameters. MAXDSIZ is the maximum that the 88# limit can be set to, and the DFLDSIZ is the default value for 89# the limit. MAXSSIZ is the maximum that the stack limit can be 90# set to. You might want to set the default lower than the max, 91# and explicitly set the maximum with a shell command for processes 92# that regularly exceed the limit like INND. 93# 94options MAXDSIZ="(1024UL*1024*1024)" 95options MAXSSIZ="(128UL*1024*1024)" 96options DFLDSIZ="(1024UL*1024*1024)" 97 98# 99# BLKDEV_IOSIZE sets the default block size used in user block 100# device I/O.

See also the 234# "remotechat" variables in the FreeBSD specific version of gdb. 235# 236options GDB_REMOTE_CHAT 237 238# 239# KTRACE enables the system-call tracing facility ktrace(2). To be more 240# SMP-friendly, KTRACE uses a worker thread to process most trace events 241# asynchronously to the thread generating the event. This requires a 242# pre-allocated store of objects representing trace events. The 243# KTRACE_REQUEST_POOL option specifies the initial size of this store. 244# The size of the pool can be adjusted both at boottime and runtime via 245# the kern.ktrace_request_pool tunable and sysctl. 246# 247options KTRACE #kernel tracing 248options KTRACE_REQUEST_POOL=101 249 250# 251# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 252# has no userland interface aside from a few sysctl's. It is enabled with 253# the KTR option. KTR_ENTRIES defines the number of entries in the circular 254# trace buffer. KTR_COMPILE defines the mask of events to compile into the 255# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 256# initial value of the ktr_mask variable which determines at runtime what 257# events to trace. KTR_CPUMASK determines which CPU's log events, with 258# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 259# to the console by default. This functionality can be toggled via the 260# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 261# 262options KTR 263options KTR_ENTRIES=1024 264options KTR_COMPILE="(KTR_INTR|KTR_PROC)" 265options KTR_MASK=KTR_INTR 266options KTR_CPUMASK=0x3 267options KTR_VERBOSE 268 269# 270# The INVARIANTS option is used in a number of source files to enable 271# extra sanity checking of internal structures.

It is a prerequisite for 281# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 282# called. The intent is that you can set 'INVARIANTS' for single 283# source files (by changing the source file or specifying it on the 284# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 285# wish to build a kernel module with 'INVARIANTS', then adding 286# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 287# infrastructure without the added overhead. 288# 289options INVARIANT_SUPPORT 290 291# 292# The DIAGNOSTIC option is used to enable extra debugging information 293# from some parts of the kernel.

These interfaces may consitute security risks 301# when enabled, as they permit processes to easily modify aspects of the 302# run-time environment to reproduce unlikely or unusual (possibly normally 303# impossible) scenarios. 304# 305options REGRESSION 306 307# 308# RESTARTABLE_PANICS allows one to continue from a panic as if it were 309# a call to the debugger via the Debugger() function instead. It is only 310# useful if a kernel debugger is present. To restart from a panic, reset 311# the panicstr variable to NULL and continue execution.

The host adapters are listed in the ISA and PCI 797# device configuration sections below. 798# 799# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 800# that a given bus, target, and LUN always come on line as the same 801# device unit. In earlier versions the unit numbers were assigned 802# in the order that the devices were probed on the SCSI bus. This 803# means that if you removed a disk drive, you may have had to rewrite 804# your /etc/fstab file, and also that you had to be careful when adding 805# a new disk as it may have been probed earlier and moved your device 806# configuration around. 807 808# This old behavior is maintained as the default behavior. The unit 809# assignment begins with the first non-wired down unit for a device 810# type. For example, if you wire a disk as "da3" then the first 811# non-wired disk will be assigned da4. 812 813# The syntax for wiring down devices is: 814 815hint.scbus.0.at="ahc0" 816hint.scbus.1.at="ahc1" 817hint.scbus.1.bus="0" 818hint.scbus.3.at="ahc2" 819hint.scbus.3.bus="0" 820hint.scbus.2.at="ahc2" 821hint.scbus.2.bus="1" 822hint.da.0.at="scbus0" 823hint.da.0.target="0" 824hint.da.0.unit="0" 825hint.da.1.at="scbus3" 826hint.da.1.target="1" 827hint.da.2.at="scbus2" 828hint.da.2.target="3" 829hint.sa.1.at="scbus1" 830hint.sa.1.target="6" 831 832# "units" (SCSI logical unit number) that are not specified are 833# treated as if specified as LUN 0. 834 835# All SCSI devices allocate as many units as are required. 836 837# The ch driver drives SCSI Media Changer ("jukebox") devices. 838# 839# The da driver drives SCSI Direct Access ("disk") and Optical Media 840# ("WORM") devices. 841# 842# The sa driver drives SCSI Sequential Access ("tape") devices. 843# 844# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 845# 846# The ses driver drives SCSI Envinronment Services ("ses") and 847# SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. 848# 849# The pt driver drives SCSI Processor devices. 850# 851# 852# Target Mode support is provided here but also requires that a SIM 853# (SCSI Host Adapter Driver) provide support as well. 854# 855# The targ driver provides target mode support as a Processor type device. 856# It exists to give the minimal context necessary to respond to Inquiry 857# commands.
