Thus, the apic device is not strictly an SMP option, 29# but it is a prerequisite for SMP. 30# 31# Notes: 32# 33# Be sure to disable 'cpu I386_CPU' for SMP kernels. 34# 35# By default, mixed mode is used to route IRQ0 from the AT timer via 36# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 37# This can be disabled via the NO_MIXED_MODE option. In that case, 38# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 39# motherboards hook IRQ0 up to the first I/O APIC even though their 40# MP table or MADT may claim to do so. That is why mixed mode is 41# enabled by default. 42# 43 44# Mandatory: 45device apic # I/O apic 46options NO_MIXED_MODE # Disable use of mixed mode 47 48 49##################################################################### 50# CPU OPTIONS 51 52# 53# You must specify at least one CPU (the one you intend to run on); 54# deleting the specification for CPUs you don't need to use may make 55# parts of the system run faster. 56# I386_CPU is mutually exclusive with the other CPU types. 57# 58#cpu I386_CPU 59cpu I486_CPU 60cpu I586_CPU # aka Pentium(tm) 61cpu I686_CPU # aka Pentium Pro(tm) 62 63# 64# Options for CPU features. 65# 66# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 67# BlueLightning CPU. It works only with Cyrix FPU, and this option 68# should not be used with Intel FPU. 69# 70# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 71# CPU if CPU supports it. The default is double-clock mode on 72# BlueLightning CPU box. 73# 74# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 75# 76# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 77# mapped mode. Default is 2-way set associative mode. 78# 79# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 80# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 81# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 82# 83# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 84# reorder). This option should not be used if you use memory mapped 85# I/O device(s). 86# 87# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 88# on I686_CPU and above. 89# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 90# 91# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 92# 93# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 94# for i386 machines. 95# 96# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 97# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 98# (no clock delay). 99# 100# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 101# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 102# The default value is 5. 103# 104# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 105# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 106# 1). 107# 108# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 109# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 110# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 111# 112# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 113# 114# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 115# enters suspend mode following execution of HALT instruction. 116# 117# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 118# 119# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 120# K5/K6/K6-2 cpus. 121# 122# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 123# flush at hold state. 124# 125# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 126# without cache flush at hold state, and (2) write-back CPU cache on 127# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 128# 129# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 130# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 131# executed. This option is only needed if I586_CPU is also defined, 132# and should be included for any non-Pentium CPU that defines it. 133# 134# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 135# which indicates that the 15-16MB range is *definitely* not being 136# occupied by an ISA memory hole. 137# 138# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 139# machines. VmWare seems to emulate this instruction poorly, causing 140# the guest OS to run very slowly. Enabling this with a SMP kernel 141# will cause the kernel to be unusable. 142# 143# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 144# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 145# These options may crash your system. 146# 147# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 148# in write-through mode when revision < 2.7. If revision of Cyrix 149# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 150# 151# NOTE 3: This option may cause failures for software that requires 152# locked cycles in order to operate correctly. 153# 154options CPU_BLUELIGHTNING_FPU_OP_CACHE 155options CPU_BLUELIGHTNING_3X 156options CPU_BTB_EN 157options CPU_DIRECT_MAPPED_CACHE 158options CPU_DISABLE_5X86_LSSER 159options CPU_ENABLE_SSE 160#options CPU_DISABLE_SSE 161options CPU_FASTER_5X86_FPU 162options CPU_I486_ON_386 163options CPU_IORT 164options CPU_L2_LATENCY=5 165options CPU_LOOP_EN 166options CPU_PPRO2CELERON 167options CPU_RSTK_EN 168options CPU_SUSP_HLT 169options CPU_UPGRADE_HW_CACHE 170options CPU_WT_ALLOC 171options CYRIX_CACHE_WORKS 172options CYRIX_CACHE_REALLY_WORKS 173#options NO_F00F_HACK 174options CPU_DISABLE_CMPXCHG 175 176# Debug options 177options NPX_DEBUG # enable npx debugging (FPU/math emu) 178 #new math emulator 179 180# 181# PERFMON causes the driver for Pentium/Pentium Pro performance counters 182# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 196# potential increase in response times. 197# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 198# to achieve smoother behaviour. 199# Additionally, you can enable/disable polling at runtime with the 200# sysctl variable kern.polling.enable (defaults off), and select 201# the CPU fraction reserved to userland with the sysctl variable 202# kern.polling.user_frac (default 50, range 0..100). 203# 204# Only the "dc" "fxp" and "sis" devices support this mode of operation at 205# the time of this writing. 206 207options DEVICE_POLLING 208 209 210##################################################################### 211# CLOCK OPTIONS 212 213# The following options are used for debugging clock behavior only, and 214# should not be used for production systems. 215# 216# CLK_CALIBRATION_LOOP will run the clock calibration loop at startup 217# until the user presses a key. 218 219options CLK_CALIBRATION_LOOP 220 221# The following two options measure the frequency of the corresponding 222# clock relative to the RTC (onboard mc146818a). 223 224options CLK_USE_I8254_CALIBRATION 225options CLK_USE_TSC_CALIBRATION 226 227 228##################################################################### 229# MISCELLANEOUS DEVICES AND OPTIONS 230 231device speaker #Play IBM BASIC-style noises out your speaker 232hint.speaker.0.at="isa" 233hint.speaker.0.port="0x35" 234device gzip #Exec gzipped a.out's.

This saves about 0.7-1.25 usec for each interrupt. 251# This option breaks suspend/resume on some portables. 252# 253# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A 254# interrupt controller. This saves about 0.7-1.25 usec for each interrupt. 255# Automatic EOI is documented not to work for for the slave with the 256# original i8259A, but it works for some clones and some integrated 257# versions. 258# 259# MAXMEM specifies the amount of RAM on the machine; if this is not 260# specified, FreeBSD will first read the amount of memory from the CMOS 261# RAM, so the amount of memory will initially be limited to 64MB or 16MB 262# depending on the BIOS. If the BIOS reports 64MB, a memory probe will 263# then attempt to detect the installed amount of RAM. If this probe 264# fails to detect >64MB RAM you will have to use the MAXMEM option. 265# The amount is in kilobytes, so for a machine with 128MB of RAM, it would 266# be 131072 (128 * 1024). 267# 268# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to 269# reset the CPU for reboot.

In addition to this, you 315# may configure a math emulator (see above). If your machine has a 316# hardware FPU and the kernel configuration includes the npx device 317# *and* a math emulator compiled into the kernel, the hardware FPU 318# will be used, unless it is found to be broken or unless "flags" to 319# npx0 includes "0x08", which requests preference for the emulator. 320device npx 321 322# 323# `flags' for npx0: 324# 0x01 don't use the npx registers to optimize bcopy. 325# 0x02 don't use the npx registers to optimize bzero. 326# 0x04 don't use the npx registers to optimize copyin or copyout. 327# 0x08 use emulator even if hardware FPU is available. 328# The npx registers are normally used to optimize copying and zeroing when 329# all of the following conditions are satisfied: 330# I586_CPU is an option 331# the cpu is an i586 (perhaps not a Pentium) 332# the probe for npx0 succeeds 333# INT 16 exception handling works. 334# Then copying and zeroing using the npx registers is normally 30-100% faster. 335# The flags can be used to control cases where it doesn't work or is slower. 336# Setting them at boot time using userconfig works right (the optimizations 337# are not used until later in the bootstrap when npx0 is attached). 338# Flag 0x08 automatically disables the i586 optimized routines. 339# 340 341# 342# Optional devices: 343# 344 345# 3Dfx Voodoo Graphics, Voodoo II /dev/3dfx CDEV support.
