The default is double-clock mode on 57# BlueLightning CPU box. 58# 59# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 60# BlueLightning CPU. It works only with Cyrix FPU, and this option 61# should not be used with Intel FPU. 62# 63# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 64# 65# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 66# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 67# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 68# 69# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 70# mapped mode. Default is 2-way set associative mode. 71# 72# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables 73# reorder). This option should not be used if you use memory mapped 74# I/O device(s). 75# 76# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 77# machines. VmWare 3.x seems to emulate this instruction poorly, causing 78# the guest OS to run very slowly. This problem appears to be fixed in 79# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 80# VmWare 4.x will result in locking operations to be 20-30 times slower. 81# Enabling this with an SMP kernel will cause the kernel to be unusable. 82# 83# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 84# 85# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 86# 87# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 88# for i386 machines. 89# 90# CPU_IORT defines I/O clock delay time (NOTE 1).

This option is used 95# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 96# The default value is 5. 97# 98# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 99# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 100# 1). 101# 102# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 103# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 104# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 105# 106# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 107# 108# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 109# enters suspend mode following execution of HALT instruction. 110# 111# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 112# 113# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 114# K5/K6/K6-2 CPUs. 115# 116# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 117# flush at hold state. 118# 119# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 120# without cache flush at hold state, and (2) write-back CPU cache on 121# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 122# 123# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 124# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 125# executed.
