1# $FreeBSD: stable/10/sys/conf/NOTES 322744 2017-08-21 10:07:12Z ae $ 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 man pages. 31# 32# A space followed by a tab separates 'options' 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 'options' 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. 48# Omitting this parameter or setting it to 0 will cause the system to 49# auto-size based on physical memory. 50# 51maxusers 10 52 53# To statically compile in device wiring instead of /boot/device.hints 54#hints "LINT.hints" # Default places to look for devices. 55 56# Use the following to compile in values accessible to the kernel 57# through getenv() (or kenv(1) in userland). The format of the file 58# is 'variable=value', see kenv(1) 59# 60#env "LINT.env" 61 62# 63# The `makeoptions' parameter allows variables to be passed to the 64# generated Makefile in the build area. 65# 66# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 67# after most other flags. Here we use it to inhibit use of non-optimal 68# gcc built-in functions (e.g., memcmp). 69# 70# DEBUG happens to be magic. 71# The following is equivalent to 'config -g KERNELNAME' and creates 72# 'kernel.debug' compiled with -g debugging as well as a normal 73# 'kernel'. Use 'make install.debug' to install the debug kernel 74# but that isn't normally necessary as the debug symbols are not loaded 75# by the kernel and are not useful there anyway. 76# 77# KERNEL can be overridden so that you can change the default name of your 78# kernel. 79# 80# MODULES_OVERRIDE can be used to limit modules built to a specific list. 81# 82makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 83#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 84#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 85# Only build ext2fs module plus those parts of the sound system I need. 86#makeoptions MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3" 87makeoptions DESTDIR=/tmp 88 89# 90# FreeBSD processes are subject to certain limits to their consumption 91# of system resources. See getrlimit(2) for more details. Each 92# resource limit has two values, a "soft" limit and a "hard" limit. 93# The soft limits can be modified during normal system operation, but 94# the hard limits are set at boot time. Their default values are 95# in sys/<arch>/include/vmparam.h. There are two ways to change them: 96# 97# 1. Set the values at kernel build time. The options below are one 98# way to allow that limit to grow to 1GB. They can be increased 99# further by changing the parameters: 100# 101# 2. In /boot/loader.conf, set the tunables kern.maxswzone, 102# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz, 103# kern.dflssiz, kern.maxssiz and kern.sgrowsiz. 104# 105# The options in /boot/loader.conf override anything in the kernel 106# configuration file. See the function init_param1 in 107# sys/kern/subr_param.c for more details. 108# 109 110options MAXDSIZ=(1024UL*1024*1024) 111options MAXSSIZ=(128UL*1024*1024) 112options DFLDSIZ=(1024UL*1024*1024) 113 114# 115# BLKDEV_IOSIZE sets the default block size used in user block 116# device I/O.

These options 200# select which scheduler is compiled in. 201# 202# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run 203# queue and no CPU affinity which makes it suboptimal for SMP. It has very 204# good interactivity and priority selection. 205# 206# SCHED_ULE provides significant performance advantages over 4BSD on many 207# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues 208# and scheduler locks. It also has a stronger notion of interactivity 209# which leads to better responsiveness even on uniprocessor machines. This 210# is the default scheduler. 211# 212# SCHED_STATS is a debugging option which keeps some stats in the sysctl 213# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions. 214# 215options SCHED_4BSD 216options SCHED_STATS 217#options SCHED_ULE 218 219##################################################################### 220# SMP OPTIONS: 221# 222# SMP enables building of a Symmetric MultiProcessor Kernel. 223 224# Mandatory: 225options SMP # Symmetric MultiProcessor Kernel 226 227# MAXCPU defines the maximum number of CPUs that can boot in the system. 228# A default value should be already present, for every architecture. 229options MAXCPU=32 230 231# MAXMEMDOM defines the maximum number of memory domains that can boot in the 232# system.

The host adapters are listed in the ISA and PCI 1229# device configuration sections below. 1230# 1231# It is possible to wire down your SCSI devices so that a given bus, 1232# target, and LUN always come on line as the same device unit. In 1233# earlier versions the unit numbers were assigned in the order that 1234# the devices were probed on the SCSI bus. This means that if you 1235# removed a disk drive, you may have had to rewrite your /etc/fstab 1236# file, and also that you had to be careful when adding a new disk 1237# as it may have been probed earlier and moved your device configuration 1238# around. (See also option GEOM_VOL for a different solution to this 1239# problem.) 1240 1241# This old behavior is maintained as the default behavior. The unit 1242# assignment begins with the first non-wired down unit for a device 1243# type. For example, if you wire a disk as "da3" then the first 1244# non-wired disk will be assigned da4. 1245 1246# The syntax for wiring down devices is: 1247 1248hint.scbus.0.at="ahc0" 1249hint.scbus.1.at="ahc1" 1250hint.scbus.1.bus="0" 1251hint.scbus.3.at="ahc2" 1252hint.scbus.3.bus="0" 1253hint.scbus.2.at="ahc2" 1254hint.scbus.2.bus="1" 1255hint.da.0.at="scbus0" 1256hint.da.0.target="0" 1257hint.da.0.unit="0" 1258hint.da.1.at="scbus3" 1259hint.da.1.target="1" 1260hint.da.2.at="scbus2" 1261hint.da.2.target="3" 1262hint.sa.1.at="scbus1" 1263hint.sa.1.target="6" 1264 1265# "units" (SCSI logical unit number) that are not specified are 1266# treated as if specified as LUN 0. 1267 1268# All SCSI devices allocate as many units as are required. 1269 1270# The ch driver drives SCSI Media Changer ("jukebox") devices. 1271# 1272# The da driver drives SCSI Direct Access ("disk") and Optical Media 1273# ("WORM") devices. 1274# 1275# The sa driver drives SCSI Sequential Access ("tape") devices. 1276# 1277# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 1278# 1279# The ses driver drives SCSI Environment Services ("ses") and 1280# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. 1281# 1282# The pt driver drives SCSI Processor devices. 1283# 1284# The sg driver provides a passthrough API that is compatible with the 1285# Linux SG driver.
