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 HTTT 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# 70#cpu I386_CPU 71cpu I486_CPU 72cpu I586_CPU # aka Pentium(tm) 73cpu I686_CPU # aka Pentium Pro(tm) 74 75# 76# Options for CPU features. 77# 78# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has 79# forgotten to enable them. 80# 81# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 82# CPU if CPU supports it. The default is double-clock mode on 83# BlueLightning CPU box. 84# 85# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 86# BlueLightning CPU. It works only with Cyrix FPU, and this option 87# should not be used with Intel FPU. 88# 89# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 90# 91# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 92# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 93# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 94# 95# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 96# mapped mode. Default is 2-way set associative mode. 97# 98# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 99# reorder). This option should not be used if you use memory mapped 100# I/O device(s). 101# 102# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 103# machines. VmWare seems to emulate this instruction poorly, causing 104# the guest OS to run very slowly. Enabling this with a SMP kernel 105# will cause the kernel to be unusable. 106# 107# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 108# 109# CPU_ELAN enables support for AMDs ElanSC520 CPU. 110# CPU_ELAN_PPS enables precision timestamp code. 111# CPU_ELAN_XTAL sets the clock crystal frequency in Hz 112# 113# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 114# on I686_CPU and above. 115# 116# CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some 117# Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected, 118# TCC allows to restrict power consumption by using machdep.cpuperf* 119# sysctls. This operates independently of SpeedStep and is useful on 120# systems where other mechanisms such as apm(4) or acpi(4) don't work. 121# 122# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 123# 124# CPU_GEODE is for the SC1100 Geode embedded processor. This option 125# is necessary because the i8254 timecounter is toast. 126# 127# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 128# for i386 machines. 129# 130# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 131# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 132# (no clock delay). 133# 134# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 135# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 136# The default value is 5. 137# 138# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 139# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 140# 1). 141# 142# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 143# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 144# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 145# 146# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 147# 148# CPU_SOEKRIS enables support www.soekris.com hardware. 149# 150# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 151# enters suspend mode following execution of HALT instruction. 152# 153# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 154# 155# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 156# K5/K6/K6-2 cpus. 157# 158# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 159# flush at hold state. 160# 161# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 162# without cache flush at hold state, and (2) write-back CPU cache on 163# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 164# 165# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 166# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 167# executed. This option is only needed if I586_CPU is also defined, 168# and should be included for any non-Pentium CPU that defines it. 169# 170# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 171# which indicates that the 15-16MB range is *definitely* not being 172# occupied by an ISA memory hole. 173# 174# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 175# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 176# These options may crash your system. 177# 178# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 179# in write-through mode when revision < 2.7. If revision of Cyrix 180# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 181# 182# NOTE 3: This option may cause failures for software that requires 183# locked cycles in order to operate correctly. 184# 185options CPU_ATHLON_SSE_HACK 186options CPU_BLUELIGHTNING_3X 187options CPU_BLUELIGHTNING_FPU_OP_CACHE 188options CPU_BTB_EN 189options CPU_DIRECT_MAPPED_CACHE 190options CPU_DISABLE_5X86_LSSER 191options CPU_DISABLE_CMPXCHG 192#options CPU_DISABLE_SSE 193options CPU_ELAN 194options CPU_ELAN_PPS 195options CPU_ELAN_XTAL=32768000 196options CPU_ENABLE_SSE 197options CPU_ENABLE_TCC 198options CPU_FASTER_5X86_FPU 199options CPU_GEODE 200options CPU_I486_ON_386 201options CPU_IORT 202options CPU_L2_LATENCY=5 203options CPU_LOOP_EN 204options CPU_PPRO2CELERON 205options CPU_RSTK_EN 206options CPU_SOEKRIS 207options CPU_SUSP_HLT 208options CPU_UPGRADE_HW_CACHE 209options CPU_WT_ALLOC 210options CYRIX_CACHE_WORKS 211options CYRIX_CACHE_REALLY_WORKS 212#options NO_F00F_HACK 213 214# Debug options 215options NPX_DEBUG # enable npx debugging 216 217# 218# PERFMON causes the driver for Pentium/Pentium Pro performance counters 219# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 233# potential increase in response times. 234# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 235# to achieve smoother behaviour. 236# Additionally, you can enable/disable polling at runtime with the 237# sysctl variable kern.polling.enable (defaults off), and select 238# the CPU fraction reserved to userland with the sysctl variable 239# kern.polling.user_frac (default 50, range 0..100). 240# 241# Not all device drivers support this mode of operation at the time of 242# this writing.
