1# $FreeBSD: stable/11/sys/conf/NOTES 309377 2016-12-01 23:37:17Z shurd $ 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 199# select which scheduler is compiled in. 200# 201# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run 202# queue and no CPU affinity which makes it suboptimal for SMP. It has very 203# good interactivity and priority selection. 204# 205# SCHED_ULE provides significant performance advantages over 4BSD on many 206# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues 207# and scheduler locks. It also has a stronger notion of interactivity 208# which leads to better responsiveness even on uniprocessor machines. This 209# is the default scheduler. 210# 211# SCHED_STATS is a debugging option which keeps some stats in the sysctl 212# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions. 213# 214options SCHED_4BSD 215options SCHED_STATS 216#options SCHED_ULE 217 218##################################################################### 219# SMP OPTIONS: 220# 221# SMP enables building of a Symmetric MultiProcessor Kernel. 222 223# Mandatory: 224options SMP # Symmetric MultiProcessor Kernel 225 226# EARLY_AP_STARTUP releases the Application Processors earlier in the 227# kernel startup process (before devices are probed) rather than at the 228# end.
