25#
26# The apic device enables the use of the I/O APIC for interrupt delivery.
27# The apic device can be used in both UP and SMP kernels, but is required
28# for SMP kernels. 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

62# Options for CPU features.
63#
64# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
65# CPU if CPU supports it. 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.

250# This option breaks suspend/resume on some portables.

252# MAXMEM specifies the amount of RAM on the machine; if this is not
253# specified, FreeBSD will first read the amount of memory from the CMOS
254# RAM, so the amount of memory will initially be limited to 64MB or 16MB
255# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
256# then attempt to detect the installed amount of RAM. If this probe
257# fails to detect >64MB RAM you will have to use the MAXMEM option.
