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# ELAN_XTAL sets the clock crystal frequency in Hz 94# ELAN_PPS enables precision timestamp code. 95# 96# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 97# on I686_CPU and above. 98# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 99# 100# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 101# 102# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 103# for i386 machines. 104# 105# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 106# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 107# (no clock delay). 108# 109# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 110# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 111# The default value is 5. 112# 113# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 114# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 115# 1). 116# 117# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 118# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 119# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 120# 121# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 122# 123# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 124# enters suspend mode following execution of HALT instruction. 125# 126# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 127# 128# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 129# K5/K6/K6-2 cpus. 130# 131# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 132# flush at hold state. 133# 134# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 135# without cache flush at hold state, and (2) write-back CPU cache on 136# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 137# 138# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 139# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 140# executed. This option is only needed if I586_CPU is also defined, 141# and should be included for any non-Pentium CPU that defines it. 142# 143# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 144# which indicates that the 15-16MB range is *definitely* not being 145# occupied by an ISA memory hole. 146# 147# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 148# machines. VmWare seems to emulate this instruction poorly, causing 149# the guest OS to run very slowly. Enabling this with a SMP kernel 150# will cause the kernel to be unusable. 151# 152# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 153# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 154# These options may crash your system. 155# 156# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 157# in write-through mode when revision < 2.7. If revision of Cyrix 158# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 159# 160# NOTE 3: This option may cause failures for software that requires 161# locked cycles in order to operate correctly. 162# 163options CPU_ATHLON_SSE_HACK 164options CPU_BLUELIGHTNING_FPU_OP_CACHE 165options CPU_BLUELIGHTNING_3X 166options CPU_BTB_EN 167options CPU_DIRECT_MAPPED_CACHE 168options CPU_DISABLE_5X86_LSSER 169options CPU_ELAN 170options ELAN_XTAL=32768000 171options ELAN_PPS 172options CPU_ENABLE_SSE 173#options CPU_DISABLE_SSE 174options CPU_FASTER_5X86_FPU 175options CPU_I486_ON_386 176options CPU_IORT 177options CPU_L2_LATENCY=5 178options CPU_LOOP_EN 179options CPU_PPRO2CELERON 180options CPU_RSTK_EN 181options CPU_SUSP_HLT 182options CPU_UPGRADE_HW_CACHE 183options CPU_WT_ALLOC 184options CYRIX_CACHE_WORKS 185options CYRIX_CACHE_REALLY_WORKS 186#options NO_F00F_HACK 187options CPU_DISABLE_CMPXCHG 188 189# 190# A math emulator is mandatory if you wish to run on hardware which 191# does not have a floating-point processor.
