1# 2# LINT -- config file for checking all the sources, tries to pull in 3# as much of the source tree as it can. 4# 5# $FreeBSD: head/sys/conf/NOTES 58236 2000-03-18 17:30:12Z asmodai $ 6# 7# NB: You probably don't want to try running a kernel built from this 8# file. Instead, you should start from GENERIC, and add options from 9# this file as required. 10# 11 12# 13# This directive is mandatory; it defines the architecture to be 14# configured for; in this case, the 386 family based IBM-PC and 15# compatibles. 16# 17machine i386 18 19# 20# This is the ``identification'' of the kernel. Usually this should 21# be the same as the name of your kernel. 22# 23ident LINT 24 25# 26# The `maxusers' parameter controls the static sizing of a number of 27# internal system tables by a complicated formula defined in param.c. 28# 29maxusers 10 30 31# 32# The `makeoptions' parameter allows variables to be passed to the 33# generated Makefile in the build area. 34# 35# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 36# after most other flags. Here we use it to inhibit use of non-optimal 37# gcc builtin functions (e.g., memcmp). 38# 39# DEBUG happens to be magic. 40# The following is equivalent to 'config -g KERNELNAME' and creates 41# 'kernel.debug' compiled with -g debugging as well as a normal 42# 'kernel'. Use 'make install.debug' to install the debug kernel 43# but that isn't normally necessary as the debug symbols are not loaded 44# by the kernel and are not useful there anyway. 45# 46# KERNEL can be overridden so that you can change the default name of your 47# kernel. 48# 49makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 50#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 51#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 52 53# 54# Certain applications can grow to be larger than the 128M limit 55# that FreeBSD initially imposes. Below are some options to 56# allow that limit to grow to 256MB, and can be increased further 57# with changing the parameters. MAXDSIZ is the maximum that the 58# limit can be set to, and the DFLDSIZ is the default value for 59# the limit. You might want to set the default lower than the 60# max, and explicitly set the maximum with a shell command for processes 61# that regularly exceed the limit like INND. 62# 63options MAXDSIZ="(256*1024*1024)" 64options DFLDSIZ="(256*1024*1024)" 65 66# 67# BLKDEV_IOSIZE sets the default block size used in user block 68# device I/O.

It works only with Cyrix FPU, and this option 148# should not be used with Intel FPU. 149# 150# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 151# CPU if CPU supports it. The default is double-clock mode on 152# BlueLightning CPU box. 153# 154# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 155# 156# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 157# mapped mode. Default is 2-way set associative mode. 158# 159# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 160# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 161# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 162# 163# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 164# reorder). This option should not be used if you use memory mapped 165# I/O device(s). 166# 167# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 168# 169# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 170# for i386 machines. 171# 172# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 173# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 174# (no clock delay). 175# 176# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 177# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 178# 1). 179# 180# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 181# 182# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 183# enters suspend mode following execution of HALT instruction. 184# 185# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 186# K5/K6/K6-2 cpus. 187# 188# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 189# flush at hold state. 190# 191# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 192# without cache flush at hold state, and (2) write-back CPU cache on 193# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 194# 195# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 196# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 197# executed. This should be included for ALL kernels that won't run 198# on a Pentium. 199# 200# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 201# which indicates that the 15-16MB range is *definitely* not being 202# occupied by an ISA memory hole. 203# 204# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 205# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 206# These options may crash your system. 207# 208# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 209# in write-through mode when revision < 2.7. If revision of Cyrix 210# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 211# 212# NOTE 3: This option may cause failures for software that requires 213# locked cycles in order to operate correctly. 214# 215options CPU_BLUELIGHTNING_FPU_OP_CACHE 216options CPU_BLUELIGHTNING_3X 217options CPU_BTB_EN 218options CPU_DIRECT_MAPPED_CACHE 219options CPU_DISABLE_5X86_LSSER 220options CPU_FASTER_5X86_FPU 221options CPU_I486_ON_386 222options CPU_IORT 223options CPU_LOOP_EN 224options CPU_RSTK_EN 225options CPU_SUSP_HLT 226options CPU_WT_ALLOC 227options CYRIX_CACHE_WORKS 228options CYRIX_CACHE_REALLY_WORKS 229#options NO_F00F_HACK 230 231# 232# A math emulator is mandatory if you wish to run on hardware which 233# does not have a floating-point processor.

It is a prerequisite for 311# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 312# called. The intent is that you can set 'INVARIANTS' for single 313# source files (by changing the source file or specifying it on the 314# command line) if you have 'INVARIANT_SUPPORT' enabled. 315# 316options INVARIANT_SUPPORT 317 318# 319# The DIAGNOSTIC option is used to enable extra debugging information 320# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 711# device configuration sections below. 712# 713# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 714# that a given bus, target, and LUN always come on line as the same 715# device unit. In earlier versions the unit numbers were assigned 716# in the order that the devices were probed on the SCSI bus. This 717# means that if you removed a disk drive, you may have had to rewrite 718# your /etc/fstab file, and also that you had to be careful when adding 719# a new disk as it may have been probed earlier and moved your device 720# configuration around. 721 722# This old behavior is maintained as the default behavior. The unit 723# assignment begins with the first non-wired down unit for a device 724# type. For example, if you wire a disk as "da3" then the first 725# non-wired disk will be assigned da4. 726 727# The syntax for wiring down devices is: 728 729# device scbus0 at ahc0 # Single bus device 730# device scbus1 at ahc1 bus 0 # Single bus device 731# device scbus3 at ahc2 bus 0 # Twin bus device 732# device scbus2 at ahc2 bus 1 # Twin bus device 733# device da0 at scbus0 target 0 unit 0 734# device da1 at scbus3 target 1 735# device da2 at scbus2 target 3 736# device sa1 at scbus1 target 6 737# device cd 738 739# "units" (SCSI logical unit number) that are not specified are 740# treated as if specified as LUN 0. 741 742# All SCSI devices allocate as many units as are required. 743 744# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 745# configuration and doesn't have to be explicitly configured. 746 747device scbus #base SCSI code 748device ch #SCSI media changers 749device da #SCSI direct access devices (aka disks) 750device sa #SCSI tapes 751device cd #SCSI CD-ROMs 752device pass #CAM passthrough driver 753device pt #SCSI processor type 754device ses #SCSI SES/SAF-TE driver 755 756# CAM OPTIONS: 757# debugging options: 758# -- NOTE -- If you specify one of the bus/target/lun options, you must 759# specify them all! 760# CAMDEBUG: When defined enables debugging macros 761# CAM_DEBUG_BUS: Debug the given bus.
