Thus, the apic device is not strictly an SMP option, 27# but it is a prerequisite for SMP. 28# 29# Notes: 30# 31# HTT CPUs should only be used if they are enabled in the BIOS. For 32# the ACPI case, ACPI only correctly tells us about any HTT CPUs if 33# they are enabled. However, most HTT systems do not list HTT CPUs 34# in the MP Table if they are enabled, thus we guess at the HTT CPUs 35# for the MP Table case. However, we shouldn't try to guess and use 36# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled 37# for the MP Table if the user explicitly asks for it via the 38# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT 39# disabled in your BIOS. 40# 41# IPI_PREEMPTION instructs the kernel to preempt threads running on other 42# CPUS if needed.

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 3.x seems to emulate this instruction poorly, causing 104# the guest OS to run very slowly. This problem appears to be fixed in 105# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 106# VmWare 4.x will result in locking operations to be 20-30 times slower. 107# Enabling this with an SMP kernel will cause the kernel to be unusable. 108# 109# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 110# 111# CPU_ELAN enables support for AMDs ElanSC520 CPU. 112# CPU_ELAN_PPS enables precision timestamp code. 113# CPU_ELAN_XTAL sets the clock crystal frequency in Hz. 114# 115# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun 116# technology which allows to restrict power consumption of the CPU by 117# using group of hw.crusoe.* sysctls. 118# 119# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 120# 121# CPU_GEODE is for the SC1100 Geode embedded processor. This option 122# is necessary because the i8254 timecounter is toast. 123# 124# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 125# for i386 machines. 126# 127# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 128# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 129# (no clock delay). 130# 131# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 132# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 133# The default value is 5. 134# 135# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 136# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 137# 1). 138# 139# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 140# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 141# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 142# 143# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 144# 145# CPU_SOEKRIS enables support www.soekris.com hardware. 146# 147# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 148# enters suspend mode following execution of HALT instruction. 149# 150# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 151# 152# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 153# K5/K6/K6-2 CPUs. 154# 155# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 156# flush at hold state. 157# 158# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 159# without cache flush at hold state, and (2) write-back CPU cache on 160# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 161# 162# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 163# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 164# executed. This option is only needed if I586_CPU is also defined, 165# and should be included for any non-Pentium CPU that defines it. 166# 167# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 168# which indicates that the 15-16MB range is *definitely* not being 169# occupied by an ISA memory hole. 170# 171# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 172# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 173# These options may crash your system. 174# 175# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 176# in write-through mode when revision < 2.7. If revision of Cyrix 177# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 178# 179# NOTE 3: This option may cause failures for software that requires 180# locked cycles in order to operate correctly. 181# 182options CPU_ATHLON_SSE_HACK 183options CPU_BLUELIGHTNING_3X 184options CPU_BLUELIGHTNING_FPU_OP_CACHE 185options CPU_BTB_EN 186options CPU_DIRECT_MAPPED_CACHE 187options CPU_DISABLE_5X86_LSSER 188options CPU_DISABLE_CMPXCHG 189#options CPU_DISABLE_SSE 190options CPU_ELAN 191options CPU_ELAN_PPS 192options CPU_ELAN_XTAL=32768000 193options CPU_ENABLE_LONGRUN 194options CPU_FASTER_5X86_FPU 195options CPU_GEODE 196options CPU_I486_ON_386 197options CPU_IORT 198options CPU_L2_LATENCY=5 199options CPU_LOOP_EN 200options CPU_PPRO2CELERON 201options CPU_RSTK_EN 202options CPU_SOEKRIS 203options CPU_SUSP_HLT 204options CPU_UPGRADE_HW_CACHE 205options CPU_WT_ALLOC 206options CYRIX_CACHE_WORKS 207options CYRIX_CACHE_REALLY_WORKS 208#options NO_F00F_HACK 209 210# Debug options 211options NPX_DEBUG # enable npx debugging 212 213# 214# PERFMON causes the driver for Pentium/Pentium Pro performance counters 215# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 246# potential increase in response times. 247# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 248# to achieve smoother behaviour. 249# Additionally, you can enable/disable polling at runtime with help of 250# the ifconfig(8) utility, and select the CPU fraction reserved to 251# userland with the sysctl variable kern.polling.user_frac 252# (default 50, range 0..100). 253# 254# Not all device drivers support this mode of operation at the time of 255# this writing.
