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

The drawback is a moderate (up to 1/HZ seconds) 213# potential increase in response times. 214# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 215# to achieve smoother behaviour. 216# Additionally, you can enable/disable polling at runtime with the 217# sysctl variable kern.polling.enable (defaults off), and select 218# the CPU fraction reserved to userland with the sysctl variable 219# kern.polling.user_frac (default 50, range 0..100). 220# 221# Only the "dc" "fxp" and "sis" devices support this mode of operation at 222# the time of this writing. 223 224options DEVICE_POLLING 225 226 227##################################################################### 228# CLOCK OPTIONS 229 230# The following options are used for debugging clock behavior only, and 231# should not be used for production systems. 232# 233# CLK_CALIBRATION_LOOP will run the clock calibration loop at startup 234# until the user presses a key. 235 236options CLK_CALIBRATION_LOOP 237 238# The following two options measure the frequency of the corresponding 239# clock relative to the RTC (onboard mc146818a). 240 241options CLK_USE_I8254_CALIBRATION 242options CLK_USE_TSC_CALIBRATION 243 244 245##################################################################### 246# MISCELLANEOUS DEVICES AND OPTIONS 247 248device speaker #Play IBM BASIC-style noises out your speaker 249hint.speaker.0.at="isa" 250hint.speaker.0.port="0x35" 251device gzip #Exec gzipped a.out's.

This saves about 0.7-1.25 usec for each interrupt. 268# This option breaks suspend/resume on some portables. 269# 270# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A 271# interrupt controller. This saves about 0.7-1.25 usec for each interrupt. 272# Automatic EOI is documented not to work for for the slave with the 273# original i8259A, but it works for some clones and some integrated 274# versions. 275# 276# MAXMEM specifies the amount of RAM on the machine; if this is not 277# specified, FreeBSD will first read the amount of memory from the CMOS 278# RAM, so the amount of memory will initially be limited to 64MB or 16MB 279# depending on the BIOS. If the BIOS reports 64MB, a memory probe will 280# then attempt to detect the installed amount of RAM. If this probe 281# fails to detect >64MB RAM you will have to use the MAXMEM option. 282# The amount is in kilobytes, so for a machine with 128MB of RAM, it would 283# be 131072 (128 * 1024). 284# 285# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to 286# reset the CPU for reboot.

In addition to this, you 332# may configure a math emulator (see above). If your machine has a 333# hardware FPU and the kernel configuration includes the npx device 334# *and* a math emulator compiled into the kernel, the hardware FPU 335# will be used, unless it is found to be broken or unless "flags" to 336# npx0 includes "0x08", which requests preference for the emulator. 337device npx 338 339# 340# `flags' for npx0: 341# 0x01 don't use the npx registers to optimize bcopy. 342# 0x02 don't use the npx registers to optimize bzero. 343# 0x04 don't use the npx registers to optimize copyin or copyout. 344# 0x08 use emulator even if hardware FPU is available. 345# The npx registers are normally used to optimize copying and zeroing when 346# all of the following conditions are satisfied: 347# I586_CPU is an option 348# the cpu is an i586 (perhaps not a Pentium) 349# the probe for npx0 succeeds 350# INT 16 exception handling works. 351# Then copying and zeroing using the npx registers is normally 30-100% faster. 352# The flags can be used to control cases where it doesn't work or is slower. 353# Setting them at boot time using userconfig works right (the optimizations 354# are not used until later in the bootstrap when npx0 is attached). 355# Flag 0x08 automatically disables the i586 optimized routines. 356# 357 358# 359# Optional devices: 360# 361 362# 3Dfx Voodoo Graphics, Voodoo II /dev/3dfx CDEV support.

The device is hooked to the PIIX4's 564# General Device 10 decoder, which means you have to fiddle with PCI 565# registers to map it in, even though it is otherwise treated here as 566# an ISA device. At the moment, the driver polls, although the device 567# is capable of generating interrupts.
