It works only with Cyrix FPU, and this option 71# should not be used with Intel FPU. 72# 73# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 74# CPU if CPU supports it. The default is double-clock mode on 75# BlueLightning CPU box. 76# 77# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 78# 79# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 80# mapped mode. Default is 2-way set associative mode. 81# 82# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 83# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 84# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 85# 86# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 87# reorder). This option should not be used if you use memory mapped 88# I/O device(s). 89# 90# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 91# on I686_CPU and above. 92# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 93# 94# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 95# 96# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 97# for i386 machines. 98# 99# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 100# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 101# (no clock delay). 102# 103# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 104# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 105# The default value is 5. 106# 107# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 108# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 109# 1). 110# 111# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 112# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 113# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 114# 115# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 116# 117# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 118# enters suspend mode following execution of HALT instruction. 119# 120# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 121# 122# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 123# K5/K6/K6-2 cpus. 124# 125# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 126# flush at hold state. 127# 128# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 129# without cache flush at hold state, and (2) write-back CPU cache on 130# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 131# 132# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 133# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 134# executed. This option is only needed if I586_CPU is also defined, 135# and should be included for any non-Pentium CPU that defines it. 136# 137# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 138# which indicates that the 15-16MB range is *definitely* not being 139# occupied by an ISA memory hole. 140# 141# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 142# machines. VmWare seems to emulate this instruction poorly, causing 143# the guest OS to run very slowly. Enabling this with a SMP kernel 144# will cause the kernel to be unusable. 145# 146# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 147# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 148# These options may crash your system. 149# 150# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 151# in write-through mode when revision < 2.7. If revision of Cyrix 152# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 153# 154# NOTE 3: This option may cause failures for software that requires 155# locked cycles in order to operate correctly. 156# 157options CPU_BLUELIGHTNING_FPU_OP_CACHE 158options CPU_BLUELIGHTNING_3X 159options CPU_BTB_EN 160options CPU_DIRECT_MAPPED_CACHE 161options CPU_DISABLE_5X86_LSSER 162options CPU_ENABLE_SSE 163#options CPU_DISABLE_SSE 164options CPU_FASTER_5X86_FPU 165options CPU_I486_ON_386 166options CPU_IORT 167options CPU_L2_LATENCY=5 168options CPU_LOOP_EN 169options CPU_PPRO2CELERON 170options CPU_RSTK_EN 171options CPU_SUSP_HLT 172options CPU_UPGRADE_HW_CACHE 173options CPU_WT_ALLOC 174options CYRIX_CACHE_WORKS 175options CYRIX_CACHE_REALLY_WORKS 176#options NO_F00F_HACK 177options CPU_DISABLE_CMPXCHG 178 179# Debug options 180options NPX_DEBUG # enable npx debugging (FPU/math emu) 181 #new math emulator 182 183# 184# PERFMON causes the driver for Pentium/Pentium Pro performance counters 185# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 199# potential increase in response times. 200# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 201# to achieve smoother behaviour. 202# Additionally, you can enable/disable polling at runtime with the 203# sysctl variable kern.polling.enable (defaults off), and select 204# the CPU fraction reserved to userland with the sysctl variable 205# kern.polling.user_frac (default 50, range 0..100). 206# 207# Only the "dc" "fxp" and "sis" devices support this mode of operation at 208# the time of this writing. 209 210options DEVICE_POLLING 211 212 213##################################################################### 214# CLOCK OPTIONS 215 216# The following options are used for debugging clock behavior only, and 217# should not be used for production systems. 218# 219# CLK_CALIBRATION_LOOP will run the clock calibration loop at startup 220# until the user presses a key. 221 222options CLK_CALIBRATION_LOOP 223 224# The following two options measure the frequency of the corresponding 225# clock relative to the RTC (onboard mc146818a). 226 227options CLK_USE_I8254_CALIBRATION 228options CLK_USE_TSC_CALIBRATION 229 230 231##################################################################### 232# MISCELLANEOUS DEVICES AND OPTIONS 233 234device speaker #Play IBM BASIC-style noises out your speaker 235hint.speaker.0.at="isa" 236hint.speaker.0.port="0x35" 237device gzip #Exec gzipped a.out's.

This saves about 0.7-1.25 usec for each interrupt. 254# This option breaks suspend/resume on some portables. 255# 256# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A 257# interrupt controller. This saves about 0.7-1.25 usec for each interrupt. 258# Automatic EOI is documented not to work for for the slave with the 259# original i8259A, but it works for some clones and some integrated 260# versions. 261# 262# MAXMEM specifies the amount of RAM on the machine; if this is not 263# specified, FreeBSD will first read the amount of memory from the CMOS 264# RAM, so the amount of memory will initially be limited to 64MB or 16MB 265# depending on the BIOS. If the BIOS reports 64MB, a memory probe will 266# then attempt to detect the installed amount of RAM. If this probe 267# fails to detect >64MB RAM you will have to use the MAXMEM option. 268# The amount is in kilobytes, so for a machine with 128MB of RAM, it would 269# be 131072 (128 * 1024). 270# 271# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to 272# reset the CPU for reboot.

In addition to this, you 318# may configure a math emulator (see above). If your machine has a 319# hardware FPU and the kernel configuration includes the npx device 320# *and* a math emulator compiled into the kernel, the hardware FPU 321# will be used, unless it is found to be broken or unless "flags" to 322# npx0 includes "0x08", which requests preference for the emulator. 323device npx 324 325# 326# `flags' for npx0: 327# 0x01 don't use the npx registers to optimize bcopy. 328# 0x02 don't use the npx registers to optimize bzero. 329# 0x04 don't use the npx registers to optimize copyin or copyout. 330# 0x08 use emulator even if hardware FPU is available. 331# The npx registers are normally used to optimize copying and zeroing when 332# all of the following conditions are satisfied: 333# I586_CPU is an option 334# the cpu is an i586 (perhaps not a Pentium) 335# the probe for npx0 succeeds 336# INT 16 exception handling works. 337# Then copying and zeroing using the npx registers is normally 30-100% faster. 338# The flags can be used to control cases where it doesn't work or is slower. 339# Setting them at boot time using userconfig works right (the optimizations 340# are not used until later in the bootstrap when npx0 is attached). 341# Flag 0x08 automatically disables the i586 optimized routines. 342# 343 344# 345# Optional devices: 346# 347 348# 3Dfx Voodoo Graphics, Voodoo II /dev/3dfx CDEV support.
