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

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 #
71 cpu I486_CPU
72 cpu I586_CPU # aka Pentium(tm)
73 cpu 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.

224 # DEVICE_POLLING adds support for mixed interrupt-polling handling
225 # of network device drivers, which has significant benefits in terms
226 # of robustness to overloads and responsivity, as well as permitting
227 # accurate scheduling of the CPU time between kernel network processing
228 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
229 # potential increase in response times.
230 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
231 # to achieve smoother behaviour.
232 # Additionally, you can enable/disable polling at runtime with help of
233 # the ifconfig(8) utility, and select the CPU fraction reserved to
