16 # SMP OPTIONS:
17 #
18 # The apic device enables the use of the I/O APIC for interrupt delivery.
19 # The apic device can be used in both UP and SMP kernels, but is required
20 # for SMP kernels. Thus, the apic device is not strictly an SMP option,
21 # but it is a prerequisite for SMP.
22 #
23 # Notes:
24 #
25 # HTT CPUs should only be used if they are enabled in the BIOS. For
26 # the ACPI case, ACPI only correctly tells us about any HTT CPUs if
27 # they are enabled. However, most HTT systems do not list HTT CPUs
28 # in the MP Table if they are enabled, thus we guess at the HTT CPUs
29 # for the MP Table case. However, we shouldn't try to guess and use
30 # these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
31 # for the MP Table if the user explicitly asks for it via the
32 # MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
33 # disabled in your BIOS.
34 #
35 # IPI_PREEMPTION instructs the kernel to preempt threads running on other
36 # CPUS if needed. Relies on the PREEMPTION option

63 # deleting the specification for CPUs you don't need to use may make
64 # parts of the system run faster.

68 cpu I686_CPU # aka Pentium Pro(tm)

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

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

782 # The host card is memory, not IO mapped.

788 # This is a temporary driver that should someday be replaced by something
789 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
790 # General Device 10 decoder, which means you have to fiddle with PCI

793 # is capable of generating interrupts. It largely undocumented.
794 # The port location in the hint is where you WANT the device to be
795 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
796 # is the only thing truly supported, but apparently a fair percentage
