Thus, the apic device is not strictly an SMP option, 28# but it is a prerequisite for SMP. 29# 30# Notes: 31# 32# Be sure to disable 'cpu I386_CPU' for SMP kernels. 33# 34# By default, mixed mode is used to route IRQ0 from the AT timer via 35# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 36# This can be disabled via the NO_MIXED_MODE option. In that case, 37# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 38# motherboards hook IRQ0 up to the first I/O APIC even though their 39# MP table or MADT may claim to do so. That is why mixed mode is 40# enabled by default. 41# 42# HTT CPUs should only be used if they are enabled in the BIOS. For 43# the ACPI case, ACPI only correctly tells us about any HTT CPUs if 44# they are enabled. However, most HTT systems do not list HTT CPUs 45# in the MP Table if they are enabled, thus we guess at the HTT CPUs 46# for the MP Table case. However, we shouldn't try to guess and use 47# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled 48# for the MP Table if the user explicitly asks for it via the 49# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT 50# disabled in your BIOS. 51# 52 53# Mandatory: 54device apic # I/O apic 55 56# Optional: 57options MPTABLE_FORCE_HTT # Enable HTT CPUs with the MP Table 58options NO_MIXED_MODE # Disable use of mixed mode 59 60 61##################################################################### 62# CPU OPTIONS 63 64# 65# You must specify at least one CPU (the one you intend to run on); 66# deleting the specification for CPUs you don't need to use may make 67# parts of the system run faster. 68# I386_CPU is mutually exclusive with the other CPU types. 69# I386_CPU is deprecated and will be removed in 6.0-RELEASE. 70# 71#cpu I386_CPU 72cpu I486_CPU 73cpu I586_CPU # aka Pentium(tm) 74cpu I686_CPU # aka Pentium Pro(tm) 75 76# 77# Options for CPU features. 78# 79# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has 80# forgotten to enable them. 81# 82# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 83# CPU if CPU supports it. The default is double-clock mode on 84# BlueLightning CPU box. 85# 86# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 87# BlueLightning CPU. It works only with Cyrix FPU, and this option 88# should not be used with Intel FPU. 89# 90# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 91# 92# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 93# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 94# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 95# 96# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 97# mapped mode. Default is 2-way set associative mode. 98# 99# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables 100# reorder). This option should not be used if you use memory mapped 101# I/O device(s). 102# 103# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 104# machines. VmWare 3.x seems to emulate this instruction poorly, causing 105# the guest OS to run very slowly. This problem appears to be fixed in 106# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 107# VmWare 4.x will result in locking operations to be 20-30 times slower. 108# Enabling this with an SMP kernel will cause the kernel to be unusable. 109# 110# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 111# 112# CPU_ELAN enables support for AMDs ElanSC520 CPU. 113# CPU_ELAN_PPS enables precision timestamp code. 114# CPU_ELAN_XTAL sets the clock crystal frequency in Hz. 115# 116# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun 117# technology which allows to restrict power consumption of the CPU by 118# using group of hw.crusoe.* sysctls. 119# 120# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 121# on I686_CPU and above. 122# 123# CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some 124# Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected, 125# TCC supports restricting power consumption using the hw.p4tcc.* 126# sysctls. This operates independently of SpeedStep and is useful on 127# systems where other mechanisms such as apm(4) or acpi(4) don't work. 128# 129# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 130# 131# CPU_GEODE is for the SC1100 Geode embedded processor. This option 132# is necessary because the i8254 timecounter is toast. 133# 134# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 135# for i386 machines. 136# 137# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 138# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 139# (no clock delay). 140# 141# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 142# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 143# The default value is 5. 144# 145# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 146# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 147# 1). 148# 149# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 150# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 151# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 152# 153# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 154# 155# CPU_SOEKRIS enables support www.soekris.com hardware. 156# 157# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 158# enters suspend mode following execution of HALT instruction. 159# 160# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 161# 162# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 163# K5/K6/K6-2 CPUs. 164# 165# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 166# flush at hold state. 167# 168# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 169# without cache flush at hold state, and (2) write-back CPU cache on 170# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 171# 172# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 173# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 174# executed. This option is only needed if I586_CPU is also defined, 175# and should be included for any non-Pentium CPU that defines it. 176# 177# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 178# which indicates that the 15-16MB range is *definitely* not being 179# occupied by an ISA memory hole. 180# 181# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 182# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 183# These options may crash your system. 184# 185# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 186# in write-through mode when revision < 2.7. If revision of Cyrix 187# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 188# 189# NOTE 3: This option may cause failures for software that requires 190# locked cycles in order to operate correctly. 191# 192options CPU_ATHLON_SSE_HACK 193options CPU_BLUELIGHTNING_3X 194options CPU_BLUELIGHTNING_FPU_OP_CACHE 195options CPU_BTB_EN 196options CPU_DIRECT_MAPPED_CACHE 197options CPU_DISABLE_5X86_LSSER 198options CPU_DISABLE_CMPXCHG 199#options CPU_DISABLE_SSE 200options CPU_ELAN 201options CPU_ELAN_PPS 202options CPU_ELAN_XTAL=32768000 203options CPU_ENABLE_LONGRUN 204options CPU_ENABLE_SSE 205options CPU_ENABLE_TCC 206options CPU_FASTER_5X86_FPU 207options CPU_GEODE 208options CPU_I486_ON_386 209options CPU_IORT 210options CPU_L2_LATENCY=5 211options CPU_LOOP_EN 212options CPU_PPRO2CELERON 213options CPU_RSTK_EN 214options CPU_SOEKRIS 215options CPU_SUSP_HLT 216options CPU_UPGRADE_HW_CACHE 217options CPU_WT_ALLOC 218options CYRIX_CACHE_WORKS 219options CYRIX_CACHE_REALLY_WORKS 220#options NO_F00F_HACK 221 222# Debug options 223options NPX_DEBUG # enable npx debugging 224 225# 226# PERFMON causes the driver for Pentium/Pentium Pro performance counters 227# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 241# potential increase in response times. 242# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 243# to achieve smoother behaviour. 244# Additionally, you can enable/disable polling at runtime with the 245# sysctl variable kern.polling.enable (defaults off), and select 246# the CPU fraction reserved to userland with the sysctl variable 247# kern.polling.user_frac (default 50, range 0..100). 248# 249# Not all device drivers support this mode of operation at the time of 250# this writing.
