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

The drawback is a moderate (up to 1/HZ seconds) 222# potential increase in response times. 223# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 224# to achieve smoother behaviour. 225# Additionally, you can enable/disable polling at runtime with the 226# sysctl variable kern.polling.enable (defaults off), and select 227# the CPU fraction reserved to userland with the sysctl variable 228# kern.polling.user_frac (default 50, range 0..100). 229# 230# Only the "dc" "fxp" and "sis" devices support this mode of operation at 231# the time of this writing. 232 233options DEVICE_POLLING 234 235 236##################################################################### 237# CLOCK OPTIONS 238 239# The following options are used for debugging clock behavior only, and 240# should not be used for production systems. 241 242# CLK_CALIBRATION_LOOP causes clock calibration to be run in a loop at 243# startup until the user presses a key.

This saves about 0.7-1.25 usec for each interrupt. 280# Automatic EOI is documented not to work for for the slave with the 281# original i8259A, but it works for some clones and some integrated 282# versions. 283# 284# MAXMEM specifies the amount of RAM on the machine; if this is not 285# specified, FreeBSD will first read the amount of memory from the CMOS 286# RAM, so the amount of memory will initially be limited to 64MB or 16MB 287# depending on the BIOS. If the BIOS reports 64MB, a memory probe will 288# then attempt to detect the installed amount of RAM. If this probe 289# fails to detect >64MB RAM you will have to use the MAXMEM option. 290# The amount is in kilobytes, so for a machine with 128MB of RAM, it would 291# be 131072 (128 * 1024). 292# 293# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to 294# reset the CPU for reboot.
