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.
