NOTES revision 91895
1# 2# NOTES -- Lines that can be cut/pasted into kernel and hints configs. 3# 4# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers', 5# 'makeoptions', 'hints' etc go into the kernel configuration that you 6# run config(8) with. 7# 8# Lines that begin with 'hints.' are NOT for config(8), they go into your 9# hints file. See /boot/device.hints and/or the 'hints' config(8) directive. 10# 11# Please use ``make LINT'' to create an old-style LINT file if you want to 12# do kernel test-builds. 13# 14# $FreeBSD: head/sys/conf/NOTES 91895 2002-03-08 15:34:23Z rwatson $ 15# 16 17# 18# This directive is mandatory; it defines the architecture to be 19# configured for; in this case, the 386 family based IBM-PC and 20# compatibles. 21# 22machine i386 23 24# 25# This is the ``identification'' of the kernel. Usually this should 26# be the same as the name of your kernel. 27# 28ident LINT 29 30# 31# The `maxusers' parameter controls the static sizing of a number of 32# internal system tables by a formula defined in subr_param.c. Setting 33# maxusers to 0 will cause the system to auto-size based on physical 34# memory. 35# 36maxusers 10 37 38# 39# We want LINT to cover profiling as well 40profile 2 41 42# 43# The `makeoptions' parameter allows variables to be passed to the 44# generated Makefile in the build area. 45# 46# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 47# after most other flags. Here we use it to inhibit use of non-optimal 48# gcc builtin functions (e.g., memcmp). 49# 50# DEBUG happens to be magic. 51# The following is equivalent to 'config -g KERNELNAME' and creates 52# 'kernel.debug' compiled with -g debugging as well as a normal 53# 'kernel'. Use 'make install.debug' to install the debug kernel 54# but that isn't normally necessary as the debug symbols are not loaded 55# by the kernel and are not useful there anyway. 56# 57# KERNEL can be overridden so that you can change the default name of your 58# kernel. 59# 60# MODULES_OVERRIDE can be used to limit modules built to a specific list. 61# 62makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 63#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 64#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 65# Only build Linux API modules and plus those parts of the sound system I need. 66#makeoptions MODULES_OVERRIDE="linux sound/snd sound/pcm sound/driver/maestro3" 67 68# 69# Certain applications can grow to be larger than the 512M limit 70# that FreeBSD initially imposes.

MAXDSIZ is the maximum that the 73# limit can be set to, and the DFLDSIZ is the default value for 74# the limit. MAXSSIZ is the maximum that the stack limit can be 75# set to. You might want to set the default lower than the max, 76# and explicitly set the maximum with a shell command for processes 77# that regularly exceed the limit like INND. 78# 79options MAXDSIZ="(1024UL*1024*1024)" 80options MAXSSIZ="(128UL*1024*1024)" 81options DFLDSIZ="(1024UL*1024*1024)" 82 83# 84# BLKDEV_IOSIZE sets the default block size used in user block 85# device I/O.

It works only with Cyrix FPU, and this option 183# should not be used with Intel FPU. 184# 185# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 186# CPU if CPU supports it. The default is double-clock mode on 187# BlueLightning CPU box. 188# 189# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 190# 191# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 192# mapped mode. Default is 2-way set associative mode. 193# 194# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 195# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 196# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 197# 198# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 199# reorder). This option should not be used if you use memory mapped 200# I/O device(s). 201# 202# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. 203# 204# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 205# 206# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 207# for i386 machines. 208# 209# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 210# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 211# (no clock delay). 212# 213# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 214# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 215# The default value is 5. 216# 217# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 218# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 219# 1). 220# 221# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 222# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 223# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 224# 225# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 226# 227# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 228# enters suspend mode following execution of HALT instruction. 229# 230# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 231# 232# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 233# K5/K6/K6-2 cpus. 234# 235# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 236# flush at hold state. 237# 238# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 239# without cache flush at hold state, and (2) write-back CPU cache on 240# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 241# 242# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 243# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 244# executed. This option is only needed if I586_CPU is also defined, 245# and should be included for any non-Pentium CPU that defines it. 246# 247# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 248# which indicates that the 15-16MB range is *definitely* not being 249# occupied by an ISA memory hole. 250# 251# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 252# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 253# These options may crash your system. 254# 255# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 256# in write-through mode when revision < 2.7. If revision of Cyrix 257# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 258# 259# NOTE 3: This option may cause failures for software that requires 260# locked cycles in order to operate correctly. 261# 262options CPU_ATHLON_SSE_HACK 263options CPU_BLUELIGHTNING_FPU_OP_CACHE 264options CPU_BLUELIGHTNING_3X 265options CPU_BTB_EN 266options CPU_DIRECT_MAPPED_CACHE 267options CPU_DISABLE_5X86_LSSER 268options CPU_ENABLE_SSE 269options CPU_FASTER_5X86_FPU 270options CPU_I486_ON_386 271options CPU_IORT 272options CPU_L2_LATENCY=5 273options CPU_LOOP_EN 274options CPU_PPRO2CELERON 275options CPU_RSTK_EN 276options CPU_SUSP_HLT 277options CPU_UPGRADE_HW_CACHE 278options CPU_WT_ALLOC 279options CYRIX_CACHE_WORKS 280options CYRIX_CACHE_REALLY_WORKS 281#options NO_F00F_HACK 282 283# 284# A math emulator is mandatory if you wish to run on hardware which 285# does not have a floating-point processor.

Currently it 346# has no userland interface aside from a few sysctl's. It is enabled with 347# the KTR option. The KTR_EXTEND option causes trace events to be generated 348# as a string from snprintf rather than as a string and up to 5 argument 349# pointers. KTR_ENTRIES defines the number of entries in the circular trace 350# buffer. KTR_COMPILE defines the mask of events to compile into the kernel 351# as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 352# initial value of the ktr_mask variable which determines at runtime what 353# events to trace. KTR_CPUMASK determines which CPU's log events, with 354# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 355# to the console by default. This functionality can be toggled via the 356# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 357# 358options KTR 359options KTR_EXTEND 360options KTR_ENTRIES=1024 361options KTR_COMPILE="(KTR_INTR|KTR_PROC)" 362options KTR_MASK=KTR_INTR 363options KTR_CPUMASK=0x3 364options KTR_VERBOSE 365 366# 367# The INVARIANTS option is used in a number of source files to enable 368# extra sanity checking of internal structures.

It is a prerequisite for 378# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 379# called. The intent is that you can set 'INVARIANTS' for single 380# source files (by changing the source file or specifying it on the 381# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 382# wish to build a kernel module with 'INVARIANTS', then adding 383# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 384# infrastructure without the added overhead. 385# 386options INVARIANT_SUPPORT 387 388# 389# The DIAGNOSTIC option is used to enable extra debugging information 390# from some parts of the kernel.
