22# SMP OPTIONS:
23#
24# The apic device enables the use of the I/O APIC for interrupt delivery.
25# The apic device can be used in both UP and SMP kernels, but is required
26# for SMP kernels. Thus, the apic device is not strictly an SMP option,
27# but it is a prerequisite for SMP.
28#
29# Notes:
30#
31# HTT CPUs should only be used if they are enabled in the BIOS. For
32# the ACPI case, ACPI only correctly tells us about any HTT CPUs if
33# they are enabled. However, most HTT systems do not list HTT CPUs
34# in the MP Table if they are enabled, thus we guess at the HTT CPUs
35# for the MP Table case. However, we shouldn't try to guess and use
36# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
37# for the MP Table if the user explicitly asks for it via the
38# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
39# disabled in your BIOS.
40#
41# IPI_PREEMPTION instructs the kernel to preempt threads running on other
42# CPUS if needed. Relies on the PREEMPTION option

64# CPU OPTIONS
65
66#
67# You must specify at least one CPU (the one you intend to run on);
68# deleting the specification for CPUs you don't need to use may make
69# parts of the system run faster.
70#
71cpu I486_CPU
72cpu I586_CPU # aka Pentium(tm)
73cpu I686_CPU # aka Pentium Pro(tm)
74
75#
76# Options for CPU features.
77#
78# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
79# forgotten to enable them.
80#
81# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
82# CPU if CPU supports it. The default is double-clock mode on
83# BlueLightning CPU box.
84#
85# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
86# BlueLightning CPU. It works only with Cyrix FPU, and this option
87# should not be used with Intel FPU.
88#
89# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
90#
91# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
92# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
93# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
94#
95# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
96# mapped mode. Default is 2-way set associative mode.
97#
98# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
99# reorder). This option should not be used if you use memory mapped
100# I/O device(s).
101#
102# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
103# machines. VmWare 3.x seems to emulate this instruction poorly, causing
104# the guest OS to run very slowly. This problem appears to be fixed in
105# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
106# VmWare 4.x will result in locking operations to be 20-30 times slower.
107# Enabling this with an SMP kernel will cause the kernel to be unusable.
108#
109# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
110#
111# CPU_ELAN enables support for AMDs ElanSC520 CPU.
112# CPU_ELAN_PPS enables precision timestamp code.
113# CPU_ELAN_XTAL sets the clock crystal frequency in Hz.
114#
115# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun
116# technology which allows to restrict power consumption of the CPU by
117# using group of hw.crusoe.* sysctls.
118#
119# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
120#
121# CPU_GEODE is for the SC1100 Geode embedded processor. This option
122# is necessary because the i8254 timecounter is toast.
123#
124# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
125# for i386 machines.
126#
127# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
128# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
129# (no clock delay).
130#
131# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
132# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
133# The default value is 5.
134#
135# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
136# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
137# 1).
138#
139# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
140# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
141# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
142#
143# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
144#
145# CPU_SOEKRIS enables support www.soekris.com hardware.
146#
147# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
148# enters suspend mode following execution of HALT instruction.
149#
150# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
151#
152# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
153# K5/K6/K6-2 CPUs.
154#
155# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
156# flush at hold state.
157#
158# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
159# without cache flush at hold state, and (2) write-back CPU cache on
160# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
161#
162# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
163# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
164# executed. This option is only needed if I586_CPU is also defined,
165# and should be included for any non-Pentium CPU that defines it.
166#
167# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
168# which indicates that the 15-16MB range is *definitely* not being
169# occupied by an ISA memory hole.
170#
171# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
172# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
173# These options may crash your system.
174#
175# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
176# in write-through mode when revision < 2.7. If revision of Cyrix
177# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
178#

180# locked cycles in order to operate correctly.

240#
241# DEVICE_POLLING adds support for mixed interrupt-polling handling
242# of network device drivers, which has significant benefits in terms
243# of robustness to overloads and responsivity, as well as permitting
244# accurate scheduling of the CPU time between kernel network processing
245# and other activities. The drawback is a moderate (up to 1/HZ seconds)
246# potential increase in response times.
247# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
248# to achieve smoother behaviour.
249# Additionally, you can enable/disable polling at runtime with help of
250# the ifconfig(8) utility, and select the CPU fraction reserved to
251# userland with the sysctl variable kern.polling.user_frac
252# (default 50, range 0..100).

307# This option breaks suspend/resume on some portables.
308#
309# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
310# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
311# Automatic EOI is documented not to work for for the slave with the

314#
315# MAXMEM specifies the amount of RAM on the machine; if this is not
316# specified, FreeBSD will first read the amount of memory from the CMOS
317# RAM, so the amount of memory will initially be limited to 64MB or 16MB
318# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
319# then attempt to detect the installed amount of RAM. If this probe

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

27# but it is a prerequisite for SMP.
28#
29# Notes:
30#
31# HTT CPUs should only be used if they are enabled in the BIOS. For
32# the ACPI case, ACPI only correctly tells us about any HTT CPUs if
33# they are enabled. However, most HTT systems do not list HTT CPUs
34# in the MP Table if they are enabled, thus we guess at the HTT CPUs
35# for the MP Table case. However, we shouldn't try to guess and use
36# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
37# for the MP Table if the user explicitly asks for it via the
38# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
39# disabled in your BIOS.

76# Options for CPU features.
77#
78# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
79# forgotten to enable them.
80#
81# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
82# CPU if CPU supports it. The default is double-clock mode on
83# BlueLightning CPU box.
84#
85# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
86# BlueLightning CPU. It works only with Cyrix FPU, and this option
87# should not be used with Intel FPU.
88#
89# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
90#
91# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
92# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
93# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
94#
95# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
96# mapped mode. Default is 2-way set associative mode.
97#
98# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
99# reorder). This option should not be used if you use memory mapped
100# I/O device(s).
101#
102# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
103# machines. VmWare 3.x seems to emulate this instruction poorly, causing
104# the guest OS to run very slowly. This problem appears to be fixed in
105# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
106# VmWare 4.x will result in locking operations to be 20-30 times slower.
107# Enabling this with an SMP kernel will cause the kernel to be unusable.
108#
109# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
110#
111# CPU_ELAN enables support for AMDs ElanSC520 CPU.
112# CPU_ELAN_PPS enables precision timestamp code.
113# CPU_ELAN_XTAL sets the clock crystal frequency in Hz.
114#
115# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun
116# technology which allows to restrict power consumption of the CPU by
117# using group of hw.crusoe.* sysctls.
118#
119# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
120#
121# CPU_GEODE is for the SC1100 Geode embedded processor. This option
122# is necessary because the i8254 timecounter is toast.
123#
124# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
125# for i386 machines.
126#
127# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
128# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
129# (no clock delay).
130#
131# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
132# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
133# The default value is 5.
134#
135# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
136# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
137# 1).
138#
139# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
140# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
141# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
142#
143# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
144#
145# CPU_SOEKRIS enables support www.soekris.com hardware.
146#
147# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
148# enters suspend mode following execution of HALT instruction.
149#
150# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
151#
152# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
153# K5/K6/K6-2 CPUs.
154#
155# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
156# flush at hold state.
157#
158# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
159# without cache flush at hold state, and (2) write-back CPU cache on
160# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
161#
162# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
163# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
164# executed. This option is only needed if I586_CPU is also defined,
165# and should be included for any non-Pentium CPU that defines it.
166#
167# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
168# which indicates that the 15-16MB range is *definitely* not being
