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. 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# KERNEL can be overridden so that you can change the default name of your 41# kernel. 42# 43#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 44#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 45 46# 47# Certain applications can grow to be larger than the 128M limit 48# that FreeBSD initially imposes. Below are some options to 49# allow that limit to grow to 256MB, and can be increased further 50# with changing the parameters. MAXDSIZ is the maximum that the 51# limit can be set to, and the DFLDSIZ is the default value for 52# the limit.

This is especially true removing 119# I386_CPU. 120# 121cpu I386_CPU 122cpu I486_CPU 123cpu I586_CPU # aka Pentium(tm) 124cpu I686_CPU # aka Pentium Pro(tm) 125 126# 127# Options for CPU features. 128# 129# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 130# BlueLightning CPU. It works only with Cyrix FPU, and this option 131# should not be used with Intel FPU. 132# 133# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 134# CPU if CPU supports it. The default is double-clock mode on 135# BlueLightning CPU box. 136# 137# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 138# 139# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 140# mapped mode. Default is 2-way set associative mode. 141# 142# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 143# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 144# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 145# 146# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 147# reorder). This option should not be used if you use memory mapped 148# I/O device(s). 149# 150# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 151# 152# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 153# for i386 machines. 154# 155# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 156# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 157# (no clock delay). 158# 159# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 160# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 161# 1). 162# 163# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 164# 165# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 166# enters suspend mode following execution of HALT instruction. 167# 168# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 169# K5/K6/K6-2 cpus. 170# 171# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 172# flush at hold state. 173# 174# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 175# without cache flush at hold state, and (2) write-back CPU cache on 176# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 177# 178# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 179# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 180# executed. This should be included for ALL kernels that won't run 181# on a Pentium. 182# 183# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 184# which indicates that the 15-16MB range is *definitely* not being 185# occupied by an ISA memory hole. 186# 187# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 188# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 189# These options may crash your system. 190# 191# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 192# in write-through mode when revision < 2.7. If revision of Cyrix 193# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 194# 195# NOTE 3: This option may cause failures for software that requires 196# locked cycles in order to operate correctly. 197# 198options CPU_BLUELIGHTNING_FPU_OP_CACHE 199options CPU_BLUELIGHTNING_3X 200options CPU_BTB_EN 201options CPU_DIRECT_MAPPED_CACHE 202options CPU_DISABLE_5X86_LSSER 203options CPU_FASTER_5X86_FPU 204options CPU_I486_ON_386 205options CPU_IORT 206options CPU_LOOP_EN 207options CPU_RSTK_EN 208options CPU_SUSP_HLT 209options CPU_WT_ALLOC 210options CYRIX_CACHE_WORKS 211options CYRIX_CACHE_REALLY_WORKS 212#options NO_F00F_HACK 213 214# 215# A math emulator is mandatory if you wish to run on hardware which 216# does not have a floating-point processor.

See also the 279# "remotechat" variables in the FreeBSD specific version of gdb. 280# 281options GDB_REMOTE_CHAT 282 283# 284# KTRACE enables the system-call tracing facility ktrace(2). 285# 286options KTRACE #kernel tracing 287 288# 289# The INVARIANTS option is used in a number of source files to enable 290# extra sanity checking of internal structures. This support is not 291# enabled by default because of the extra time it would take to check 292# for these conditions, which can only occur as a result of 293# programming errors. 294# 295options INVARIANTS 296 297# 298# The INVARIANT_SUPPORT option makes us compile in support for 299# verifying some of the internal structures. It is a prerequisite for 300# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 301# called. The intent is that you can set 'INVARIANTS' for single 302# source files (by changing the source file or specifying it on the 303# command line) if you have 'INVARIANT_SUPPORT' enabled. 304# 305options INVARIANT_SUPPORT 306 307# 308# The DIAGNOSTIC option is used to enable extra debugging information 309# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 654# device configuration sections below. 655# 656# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 657# that a given bus, target, and LUN always come on line as the same 658# device unit. In earlier versions the unit numbers were assigned 659# in the order that the devices were probed on the SCSI bus. This 660# means that if you removed a disk drive, you may have had to rewrite 661# your /etc/fstab file, and also that you had to be careful when adding 662# a new disk as it may have been probed earlier and moved your device 663# configuration around. 664 665# This old behavior is maintained as the default behavior. The unit 666# assignment begins with the first non-wired down unit for a device 667# type. For example, if you wire a disk as "da3" then the first 668# non-wired disk will be assigned da4. 669 670# The syntax for wiring down devices is: 671 672# controller scbus0 at ahc0 # Single bus device 673# controller scbus1 at ahc1 bus 0 # Single bus device 674# controller scbus3 at ahc2 bus 0 # Twin bus device 675# controller scbus2 at ahc2 bus 1 # Twin bus device 676# disk da0 at scbus0 target 0 unit 0 677# disk da1 at scbus3 target 1 678# disk da2 at scbus2 target 3 679# tape sa1 at scbus1 target 6 680# device cd0 at scbus? 681 682# "units" (SCSI logical unit number) that are not specified are 683# treated as if specified as LUN 0. 684 685# All SCSI devices allocate as many units as are required. 686 687# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 688# configuration and doesn't have to be explicitly configured. 689 690controller scbus0 #base SCSI code 691device ch0 #SCSI media changers 692device da0 #SCSI direct access devices (aka disks) 693device sa0 #SCSI tapes 694device cd0 #SCSI CD-ROMs 695device pass0 #CAM passthrough driver 696 697# The previous devices (ch, da, st, cd) are recognized by config. 698# config doesn't (and shouldn't) know about these newer ones, 699# so we have to specify that they are on a SCSI bus with the "at scbus?" 700# clause. 701 702device pt0 at scbus? # SCSI processor type 703 704# CAM OPTIONS: 705# debugging options: 706# -- NOTE -- If you specify one of the bus/target/lun options, you must 707# specify them all! 708# CAMDEBUG: When defined enables debugging macros 709# CAM_DEBUG_BUS: Debug the given bus.
