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).

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.

The host adapters are listed in the ISA and PCI 1244# device configuration sections below. 1245# 1246# It is possible to wire down your SCSI devices so that a given bus, 1247# target, and LUN always come on line as the same device unit. In 1248# earlier versions the unit numbers were assigned in the order that 1249# the devices were probed on the SCSI bus. This means that if you 1250# removed a disk drive, you may have had to rewrite your /etc/fstab 1251# file, and also that you had to be careful when adding a new disk 1252# as it may have been probed earlier and moved your device configuration 1253# around. (See also option GEOM_VOL for a different solution to this 1254# problem.) 1255 1256# This old behavior is maintained as the default behavior. The unit 1257# assignment begins with the first non-wired down unit for a device 1258# type. For example, if you wire a disk as "da3" then the first 1259# non-wired disk will be assigned da4. 1260 1261# The syntax for wiring down devices is: 1262 1263hint.scbus.0.at="ahc0" 1264hint.scbus.1.at="ahc1" 1265hint.scbus.1.bus="0" 1266hint.scbus.3.at="ahc2" 1267hint.scbus.3.bus="0" 1268hint.scbus.2.at="ahc2" 1269hint.scbus.2.bus="1" 1270hint.da.0.at="scbus0" 1271hint.da.0.target="0" 1272hint.da.0.unit="0" 1273hint.da.1.at="scbus3" 1274hint.da.1.target="1" 1275hint.da.2.at="scbus2" 1276hint.da.2.target="3" 1277hint.sa.1.at="scbus1" 1278hint.sa.1.target="6" 1279 1280# "units" (SCSI logical unit number) that are not specified are 1281# treated as if specified as LUN 0. 1282 1283# All SCSI devices allocate as many units as are required. 1284 1285# The ch driver drives SCSI Media Changer ("jukebox") devices. 1286# 1287# The da driver drives SCSI Direct Access ("disk") and Optical Media 1288# ("WORM") devices. 1289# 1290# The sa driver drives SCSI Sequential Access ("tape") devices. 1291# 1292# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 1293# 1294# The ses driver drives SCSI Environment Services ("ses") and 1295# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. 1296# 1297# The pt driver drives SCSI Processor devices. 1298# 1299# The sg driver provides a passthrough API that is compatible with the 1300# Linux SG driver.
