40# The apic device enables the use of the I/O APIC for interrupt delivery.
41# The apic device can be used in both UP and SMP kernels, but is required
42# for SMP kernels. Thus, the apic device is not strictly an SMP option,
43# but it is a prerequisite for SMP.
44#
45# Notes:
46#
47# HTT CPUs should only be used if they are enabled in the BIOS. For
48# the ACPI case, ACPI only correctly tells us about any HTT CPUs if
49# they are enabled. However, most HTT systems do not list HTT CPUs
50# in the MP Table if they are enabled, thus we guess at the HTT CPUs
51# for the MP Table case. However, we shouldn't try to guess and use
52# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
53# for the MP Table if the user explicitly asks for it via the
54# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
55# disabled in your BIOS.

92# Options for CPU features.
93#
94# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
95# forgotten to enable them.
96#
97# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
98# CPU if CPU supports it. The default is double-clock mode on
99# BlueLightning CPU box.
100#
101# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
102# BlueLightning CPU. It works only with Cyrix FPU, and this option
103# should not be used with Intel FPU.
104#
105# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
106#
107# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
108# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
109# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
110#
111# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
112# mapped mode. Default is 2-way set associative mode.
113#
114# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
115# reorder). This option should not be used if you use memory mapped
116# I/O device(s).
117#
118# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
119# machines. VmWare 3.x seems to emulate this instruction poorly, causing
120# the guest OS to run very slowly. This problem appears to be fixed in
121# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
122# VmWare 4.x will result in locking operations to be 20-30 times slower.
123# Enabling this with an SMP kernel will cause the kernel to be unusable.
124#
125# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
126#
127# CPU_ELAN enables support for AMDs ElanSC520 CPU.
128# CPU_ELAN_PPS enables precision timestamp code.
129# CPU_ELAN_XTAL sets the clock crystal frequency in Hz.
130#
131# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun
132# technology which allows to restrict power consumption of the CPU by
133# using group of hw.crusoe.* sysctls.
134#
135# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
136#
137# CPU_GEODE is for the SC1100 Geode embedded processor. This option
138# is necessary because the i8254 timecounter is toast.
139#
140# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
141# for i386 machines.
142#
143# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
144# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
145# (no clock delay).
146#
147# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
148# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
149# The default value is 5.
150#
151# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
152# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
153# 1).
154#
155# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
156# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
157# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
158#
159# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
160#
161# CPU_SOEKRIS enables support www.soekris.com hardware.
162#
163# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
164# enters suspend mode following execution of HALT instruction.
165#
166# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
167#
168# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
169# K5/K6/K6-2 CPUs.
170#
171# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
172# flush at hold state.
173#
174# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
175# without cache flush at hold state, and (2) write-back CPU cache on
176# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
177#
178# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
179# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
180# executed. This option is only needed if I586_CPU is also defined,
181# and should be included for any non-Pentium CPU that defines it.
182#
183# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
184# which indicates that the 15-16MB range is *definitely* not being
185# occupied by an ISA memory hole.
186#
187# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,

45# Notes:
46#
47# HTT CPUs should only be used if they are enabled in the BIOS. For
48# the ACPI case, ACPI only correctly tells us about any HTT CPUs if
49# they are enabled. However, most HTT systems do not list HTT CPUs
50# in the MP Table if they are enabled, thus we guess at the HTT CPUs
51# for the MP Table case. However, we shouldn't try to guess and use
52# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled

145# (no clock delay).
146#
147# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used

154#
155# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
156# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
157# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.

175# without cache flush at hold state, and (2) write-back CPU cache on
176# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
177#
178# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
179# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
180# executed. This option is only needed if I586_CPU is also defined,
181# and should be included for any non-Pentium CPU that defines it.
182#
183# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
184# which indicates that the 15-16MB range is *definitely* not being

258# of network device drivers, which has significant benefits in terms
259# of robustness to overloads and responsivity, as well as permitting
260# accurate scheduling of the CPU time between kernel network processing

862# Notes on the Sony Programmable I/O controller
863# This is a temporary driver that should someday be replaced by something
864# that hooks into the ACPI layer. The device is hooked to the PIIX4's
865# General Device 10 decoder, which means you have to fiddle with PCI
866# registers to map it in, even though it is otherwise treated here as
867# an ISA device. At the moment, the driver polls, although the device
868# is capable of generating interrupts. It largely undocumented.
869# The port location in the hint is where you WANT the device to be
870# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
871# is the only thing truly supported, but apparently a fair percentage
