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.

DEBUG happens to be magic. 34# The following is equivalent to 'config -g KERNELNAME' and creates 35# 'kernel.debug' compiled with -g debugging as well as a normal 36# 'kernel'. Use 'make install.debug' to install the debug kernel 37# but that isn't normally necessary as the debug symbols are not loaded 38# by the kernel and are not useful there anyway. 39# 40#makeoptions DEBUG="-g" #Build kernel with gdb(1) debug symbols 41 42# 43# Certain applications can grow to be larger than the 128M limit 44# that FreeBSD initially imposes. Below are some options to 45# allow that limit to grow to 256MB, and can be increased further 46# with changing the parameters. MAXDSIZ is the maximum that the 47# limit can be set to, and the DFLDSIZ is the default value for 48# the limit. You might want to set the default lower than the 49# max, and explicitly set the maximum with a shell command for processes 50# that regularly exceed the limit like INND. 51# 52options "MAXDSIZ=(256*1024*1024)" 53options "DFLDSIZ=(256*1024*1024)" 54 55# When this is set, be extra conservative in various parts of the kernel 56# and choose functionality over speed (on the widest variety of systems). 57options FAILSAFE 58 59# Options for the VM subsystem 60#options PQ_NOOPT # No coloring 61options PQ_LARGECACHE # color for 512k/16k cache 62#options PQ_HUGECACHE # color for 1024k/16k cache 63 64# This allows you to actually store this configuration file into 65# the kernel binary itself, where it may be later read by saying: 66# strings -aout -n 3 /kernel | grep ^___ | sed -e 's/^___//' > MYKERNEL 67# 68options INCLUDE_CONFIG_FILE # Include this file in kernel 69 70# 71# This directive defines a number of things: 72# - The compiled kernel is to be called `kernel' 73# - The root filesystem might be on partition wd0a 74# - Crash dumps will be written to wd0b, if possible.

It works only with Cyrix FPU, and this option 140# should not be used with Intel FPU. 141# 142# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 143# CPU if CPU supports it. The default is double-clock mode on 144# BlueLightning CPU box. 145# 146# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 147# 148# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 149# mapped mode. Default is 2-way set associative mode. 150# 151# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 152# of Cyrix 6x86 and 6x86MX CPUs. If this option is not set and 153# FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared. (NOTE 3) 154# 155# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 156# reorder). This option should not be used if you use memory mapped 157# I/O device(s). 158# 159# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 160# 161# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 162# for i386 machines. 163# 164# CPU_IORT defines I/O clock delay time (NOTE 1). Default vaules of 165# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 166# (no clock delay). 167# 168# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 169# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 170# 1). 171# 172# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 173# 174# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 175# enters suspend mode following execution of HALT instruction. 176# 177# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 178# K5/K6/K6-2 cpus. 179# 180# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 181# flush at hold state. 182# 183# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 184# without cache flush at hold state, and (2) write-back CPU cache on 185# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 186# 187# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 188# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 189# executed.

See also the 295# "remotechat" variables in the FreeBSD specific version of gdb. 296# 297options GDB_REMOTE_CHAT 298 299# 300# KTRACE enables the system-call tracing facility ktrace(2). 301# 302options KTRACE #kernel tracing 303 304# 305# The INVARIANTS option is used in a number of source files to enable 306# extra sanity checking of internal structures. This support is not 307# enabled by default because of the extra time it would take to check 308# for these conditions, which can only occur as a result of 309# programming errors. 310# 311options INVARIANTS 312 313# 314# The INVARIANT_SUPPORT option makes us compile in support for 315# verifying some of the internal structures. It is a prerequisite for 316# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 317# called. The intent is that you can set 'INVARIANTS' for single 318# source files (by changing the source file or specifying it on the 319# command line) if you have 'INVARIANT_SUPPORT' enabled. 320# 321options INVARIANT_SUPPORT 322 323# 324# The DIAGNOSTIC option is used to enable extra debugging information 325# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 673# device configuration sections below. 674# 675# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 676# that a given bus, target, and LUN always come on line as the same 677# device unit. In earlier versions the unit numbers were assigned 678# in the order that the devices were probed on the SCSI bus. This 679# means that if you removed a disk drive, you may have had to rewrite 680# your /etc/fstab file, and also that you had to be careful when adding 681# a new disk as it may have been probed earlier and moved your device 682# configuration around. 683 684# This old behavior is maintained as the default behavior. The unit 685# assignment begins with the first non-wired down unit for a device 686# type. For example, if you wire a disk as "da3" then the first 687# non-wired disk will be assigned da4. 688 689# The syntax for wiring down devices is: 690 691# controller scbus0 at ahc0 # Single bus device 692# controller scbus1 at ahc1 bus 0 # Single bus device 693# controller scbus3 at ahc2 bus 0 # Twin bus device 694# controller scbus2 at ahc2 bus 1 # Twin bus device 695# disk da0 at scbus0 target 0 unit 0 696# disk da1 at scbus3 target 1 697# disk da2 at scbus2 target 3 698# tape st1 at scbus1 target 6 699# device cd0 at scbus? 700 701# "units" (SCSI logical unit number) that are not specified are 702# treated as if specified as LUN 0. 703 704# All SCSI devices allocate as many units as are required. 705 706# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 707# configuration and doesn't have to be explicitly configured. 708 709controller scbus0 #base SCSI code 710device ch0 #SCSI media changers 711device da0 #SCSI direct access devices (aka disks) 712device sa0 #SCSI tapes 713device cd0 #SCSI CD-ROMs 714#device od0 #SCSI optical disk 715device pass0 #CAM passthrough driver 716 717# The previous devices (ch, da, st, cd) are recognized by config. 718# config doesn't (and shouldn't) know about these newer ones, 719# so we have to specify that they are on a SCSI bus with the "at scbus?" 720# clause. 721 722device pt0 at scbus? # SCSI processor type 723device sctarg0 at scbus? # SCSI target 724 725# CAM OPTIONS: 726# debugging options: 727# -- NOTE -- If you specify one of the bus/target/lun options, you must 728# specify them all! 729# CAMDEBUG: When defined enables debugging macros 730# CAM_DEBUG_BUS: Debug the given bus.
