Thus, the apic device is not strictly an SMP option, 29122755Snyan# but it is a prerequisite for SMP. 30111314Snyan# 31111314Snyan# Notes: 32111314Snyan# 33122755Snyan# Be sure to disable 'cpu I386_CPU' for SMP kernels. 34111314Snyan# 35122755Snyan# By default, mixed mode is used to route IRQ0 from the AT timer via 36122755Snyan# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 37122755Snyan# This can be disabled via the NO_MIXED_MODE option. In that case, 38122755Snyan# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 39122755Snyan# motherboards hook IRQ0 up to the first I/O APIC even though their 40122755Snyan# MP table or MADT may claim to do so.

It works only with Cyrix FPU, and this option 68111314Snyan# should not be used with Intel FPU. 69111314Snyan# 70111314Snyan# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 71111314Snyan# CPU if CPU supports it. The default is double-clock mode on 72111314Snyan# BlueLightning CPU box. 73111314Snyan# 74111314Snyan# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 75111314Snyan# 76111314Snyan# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 77111314Snyan# mapped mode. Default is 2-way set associative mode. 78111314Snyan# 79111314Snyan# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 80111314Snyan# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 81111314Snyan# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 82111314Snyan# 83111314Snyan# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 84111314Snyan# reorder). This option should not be used if you use memory mapped 85111314Snyan# I/O device(s). 86111314Snyan# 87111314Snyan# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 88111314Snyan# on I686_CPU and above. 89111314Snyan# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 90111314Snyan# 91111314Snyan# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 92111314Snyan# 93111314Snyan# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 94111314Snyan# for i386 machines. 95111314Snyan# 96111314Snyan# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 97111314Snyan# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 98111314Snyan# (no clock delay). 99111314Snyan# 100111314Snyan# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 101111314Snyan# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 102111314Snyan# The default value is 5. 103111314Snyan# 104111314Snyan# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 105111314Snyan# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 106111314Snyan# 1). 107111314Snyan# 108111314Snyan# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 109111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 110111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 111111314Snyan# 112111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 113111314Snyan# 114111314Snyan# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 115111314Snyan# enters suspend mode following execution of HALT instruction. 116111314Snyan# 117111314Snyan# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 118111314Snyan# 119111314Snyan# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 120111314Snyan# K5/K6/K6-2 cpus. 121111314Snyan# 122111314Snyan# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 123111314Snyan# flush at hold state. 124111314Snyan# 125111314Snyan# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 126111314Snyan# without cache flush at hold state, and (2) write-back CPU cache on 127111314Snyan# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 128111314Snyan# 129111314Snyan# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 130111314Snyan# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 131111314Snyan# executed. This option is only needed if I586_CPU is also defined, 132111314Snyan# and should be included for any non-Pentium CPU that defines it. 133111314Snyan# 134111314Snyan# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 135111314Snyan# which indicates that the 15-16MB range is *definitely* not being 136111314Snyan# occupied by an ISA memory hole. 137111314Snyan# 138111314Snyan# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 139111314Snyan# machines. VmWare seems to emulate this instruction poorly, causing 140111314Snyan# the guest OS to run very slowly. Enabling this with a SMP kernel 141111314Snyan# will cause the kernel to be unusable. 142111314Snyan# 143111314Snyan# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 144111314Snyan# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 145111314Snyan# These options may crash your system. 146111314Snyan# 147111314Snyan# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 148111314Snyan# in write-through mode when revision < 2.7.

The drawback is a moderate (up to 1/HZ seconds) 196111314Snyan# potential increase in response times. 197111314Snyan# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 198111314Snyan# to achieve smoother behaviour. 199111314Snyan# Additionally, you can enable/disable polling at runtime with the 200111314Snyan# sysctl variable kern.polling.enable (defaults off), and select 201111314Snyan# the CPU fraction reserved to userland with the sysctl variable 202111314Snyan# kern.polling.user_frac (default 50, range 0..100). 203111314Snyan# 204124408Snyan# Not all device drivers support this mode of operation at the time of 205124408Snyan# this writing.
