It works only with Cyrix FPU, and this option 73# should not be used with Intel FPU. 74# 75# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 76# CPU if CPU supports it. The default is double-clock mode on 77# BlueLightning CPU box. 78# 79# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 80# 81# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 82# mapped mode. Default is 2-way set associative mode. 83# 84# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 85# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 86# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 87# 88# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 89# reorder). This option should not be used if you use memory mapped 90# I/O device(s). 91# 92# CPU_ELAN enables support for AMDs ElanSC520 CPU. 93# 94# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 95# on I686_CPU and above. 96# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 97# 98# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 99# 100# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 101# for i386 machines. 102# 103# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 104# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 105# (no clock delay). 106# 107# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 108# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 109# The default value is 5. 110# 111# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 112# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 113# 1). 114# 115# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 116# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 117# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 118# 119# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 120# 121# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 122# enters suspend mode following execution of HALT instruction. 123# 124# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 125# 126# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 127# K5/K6/K6-2 cpus. 128# 129# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 130# flush at hold state. 131# 132# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 133# without cache flush at hold state, and (2) write-back CPU cache on 134# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 135# 136# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 137# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 138# executed. This option is only needed if I586_CPU is also defined, 139# and should be included for any non-Pentium CPU that defines it. 140# 141# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 142# which indicates that the 15-16MB range is *definitely* not being 143# occupied by an ISA memory hole. 144# 145# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 146# machines. VmWare seems to emulate this instruction poorly, causing 147# the guest OS to run very slowly. Enabling this with a SMP kernel 148# will cause the kernel to be unusable. 149# 150# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 151# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 152# These options may crash your system. 153# 154# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 155# in write-through mode when revision < 2.7. If revision of Cyrix 156# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 157# 158# NOTE 3: This option may cause failures for software that requires 159# locked cycles in order to operate correctly. 160# 161options CPU_ATHLON_SSE_HACK 162options CPU_BLUELIGHTNING_FPU_OP_CACHE 163options CPU_BLUELIGHTNING_3X 164options CPU_BTB_EN 165options CPU_DIRECT_MAPPED_CACHE 166options CPU_DISABLE_5X86_LSSER 167options CPU_ELAN 168options CPU_ENABLE_SSE 169#options CPU_DISABLE_SSE 170options CPU_FASTER_5X86_FPU 171options CPU_I486_ON_386 172options CPU_IORT 173options CPU_L2_LATENCY=5 174options CPU_LOOP_EN 175options CPU_PPRO2CELERON 176options CPU_RSTK_EN 177options CPU_SUSP_HLT 178options CPU_UPGRADE_HW_CACHE 179options CPU_WT_ALLOC 180options CYRIX_CACHE_WORKS 181options CYRIX_CACHE_REALLY_WORKS 182#options NO_F00F_HACK 183options CPU_DISABLE_CMPXCHG 184 185# 186# A math emulator is mandatory if you wish to run on hardware which 187# does not have a floating-point processor.
