1# $FreeBSD: head/sys/conf/NOTES 176868 2008-03-06 08:09:45Z rink $ 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# 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 built-in 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 ext2fs module plus those parts of the sound system I need. 77#makeoptions MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3" 78makeoptions DESTDIR=/tmp 79 80# 81# FreeBSD processes are subject to certain limits to their consumption 82# of system resources. See getrlimit(2) for more details. Each 83# resource limit has two values, a "soft" limit and a "hard" limit. 84# The soft limits can be modified during normal system operation, but 85# the hard limits are set at boot time. Their default values are 86# in sys/<arch>/include/vmparam.h. There are two ways to change them: 87# 88# 1. Set the values at kernel build time. The options below are one 89# way to allow that limit to grow to 1GB. They can be increased 90# further by changing the parameters: 91# 92# 2. In /boot/loader.conf, set the tunables kern.maxswzone, 93# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz, 94# kern.dflssiz, kern.maxssiz and kern.sgrowsiz. 95# 96# The options in /boot/loader.conf override anything in the kernel 97# configuration file. See the function init_param1 in 98# sys/kern/subr_param.c for more details. 99# 100 101options MAXDSIZ=(1024UL*1024*1024) 102options MAXSSIZ=(128UL*1024*1024) 103options DFLDSIZ=(1024UL*1024*1024) 104 105# 106# BLKDEV_IOSIZE sets the default block size used in user block 107# device I/O.

These options 176# select which scheduler is compiled in. 177# 178# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run 179# queue and no CPU affinity which makes it suboptimal for SMP. It has very 180# good interactivity and priority selection. 181# 182# SCHED_ULE provides significant performance advantages over 4BSD on many 183# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues 184# and scheduler locks. It also has a stronger notion of interactivity 185# which leads to better responsiveness even on uniprocessor machines. This 186# will eventually become the default scheduler. 187# 188options SCHED_4BSD 189#options SCHED_ULE 190 191##################################################################### 192# SMP OPTIONS: 193# 194# SMP enables building of a Symmetric MultiProcessor Kernel. 195 196# Mandatory: 197options SMP # Symmetric MultiProcessor Kernel 198 199# ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin 200# if the thread that currently owns the mutex is executing on another 201# CPU.
