Thus, the apic device is not strictly an SMP option, 29# but it is a prerequisite for SMP. 30# 31# Notes: 32# 33# By default, mixed mode is used to route IRQ0 from the AT timer via 34# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 35# This can be disabled via the NO_MIXED_MODE option. In that case, 36# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 37# motherboards hook IRQ0 up to the first I/O APIC even though their 38# MP table or MADT may claim to do so.

The default is double-clock mode on 66# BlueLightning CPU box. 67# 68# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 69# BlueLightning CPU. It works only with Cyrix FPU, and this option 70# should not be used with Intel FPU. 71# 72# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 73# 74# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 75# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 76# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 77# 78# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 79# mapped mode. Default is 2-way set associative mode. 80# 81# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables 82# reorder). This option should not be used if you use memory mapped 83# I/O device(s). 84# 85# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 86# machines. VmWare 3.x seems to emulate this instruction poorly, causing 87# the guest OS to run very slowly. This problem appears to be fixed in 88# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 89# VmWare 4.x will result in locking operations to be 20-30 times slower. 90# Enabling this with an SMP kernel will cause the kernel to be unusable. 91# 92# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 93# 94# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 95# on I686_CPU and above. 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 specifies 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# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 145# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 146# These options may crash your system. 147# 148# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 149# in write-through mode when revision < 2.7. If revision of Cyrix 150# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 151# 152# NOTE 3: This option may cause failures for software that requires 153# locked cycles in order to operate correctly. 154# 155options CPU_BLUELIGHTNING_3X 156options CPU_BLUELIGHTNING_FPU_OP_CACHE 157options CPU_BTB_EN 158options CPU_DIRECT_MAPPED_CACHE 159options CPU_DISABLE_5X86_LSSER 160options CPU_DISABLE_CMPXCHG 161#options CPU_DISABLE_SSE 162options CPU_ENABLE_SSE 163options CPU_FASTER_5X86_FPU 164options CPU_I486_ON_386 165options CPU_IORT 166options CPU_L2_LATENCY=5 167options CPU_LOOP_EN 168options CPU_PPRO2CELERON 169options CPU_RSTK_EN 170options CPU_SUSP_HLT 171options CPU_UPGRADE_HW_CACHE 172options CPU_WT_ALLOC 173options CYRIX_CACHE_WORKS 174options CYRIX_CACHE_REALLY_WORKS 175#options NO_F00F_HACK 176 177# Debug options 178options NPX_DEBUG # enable npx debugging 179 180# 181# PERFMON causes the driver for Pentium/Pentium Pro performance counters 182# to be compiled.
