It works only with Cyrix FPU, and this option 69# should not be used with Intel FPU. 70# 71# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 72# CPU if CPU supports it. The default is double-clock mode on 73# BlueLightning CPU box. 74# 75# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 76# 77# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 78# mapped mode. Default is 2-way set associative mode. 79# 80# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 81# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 82# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 83# 84# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 85# reorder). This option should not be used if you use memory mapped 86# I/O device(s). 87# 88# CPU_ELAN enables support for AMDs ElanSC520 CPU. 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# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 142# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 143# These options may crash your system. 144# 145# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 146# in write-through mode when revision < 2.7. If revision of Cyrix 147# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 148# 149# NOTE 3: This option may cause failures for software that requires 150# locked cycles in order to operate correctly. 151# 152options CPU_ATHLON_SSE_HACK 153options CPU_BLUELIGHTNING_FPU_OP_CACHE 154options CPU_BLUELIGHTNING_3X 155options CPU_BTB_EN 156options CPU_DIRECT_MAPPED_CACHE 157options CPU_DISABLE_5X86_LSSER 158options CPU_ELAN 159options CPU_ENABLE_SSE 160#options CPU_DISABLE_SSE 161options CPU_FASTER_5X86_FPU 162options CPU_I486_ON_386 163options CPU_IORT 164options CPU_L2_LATENCY=5 165options CPU_LOOP_EN 166options CPU_PPRO2CELERON 167options CPU_RSTK_EN 168options CPU_SUSP_HLT 169options CPU_UPGRADE_HW_CACHE 170options CPU_WT_ALLOC 171options CYRIX_CACHE_WORKS 172options CYRIX_CACHE_REALLY_WORKS 173#options NO_F00F_HACK 174 175# 176# A math emulator is mandatory if you wish to run on hardware which 177# does not have a floating-point processor.
