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 # Be sure to disable 'cpu I386_CPU' for SMP kernels.
33 #
34 # By default, mixed mode is used to route IRQ0 from the AT timer via
35 # the 8259A master PIC through the ExtINT pin on the first I/O APIC.
36 # This can be disabled via the NO_MIXED_MODE option. In that case,
37 # IRQ0 will be routed via an intpin on the first I/O APIC. Not all
38 # motherboards hook IRQ0 up to the first I/O APIC even though their
39 # MP table or MADT may claim to do so. That is why mixed mode is
40 # enabled by default.
41 #
42 # HTT CPUs should only be used if they are enabled in the BIOS. For
43 # the ACPI case, ACPI only correctly tells us about any HTT CPUs if
44 # they are enabled. However, most HTT systems do not list HTT CPUs
45 # in the MP Table if they are enabled, thus we guess at the HTT CPUs
46 # for the MP Table case. However, we shouldn't try to guess and use
47 # these CPUs if HTTT is disabled. Thus, HTT guessing is only enabled
48 # for the MP Table if the user explicitly asks for it via the
49 # MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
50 # disabled in your BIOS.
51 #
52
53 # Mandatory:

78 # CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
79 # forgotten to enable them.
80 #
81 # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
82 # BlueLightning CPU. It works only with Cyrix FPU, and this option
83 # should not be used with Intel FPU.
84 #
85 # CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
86 # CPU if CPU supports it. The default is double-clock mode on
87 # BlueLightning CPU box.
88 #
89 # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
90 #
91 # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
92 # mapped mode. Default is 2-way set associative mode.
93 #
94 # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
95 # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
96 # Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
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_ELAN enables support for AMDs ElanSC520 CPU.
103 # CPU_ELAN_XTAL sets the clock crystal frequency in Hz
104 # CPU_ELAN_PPS enables precision timestamp code.
105 #
106 # CPU_SOEKRIS enables support www.soekris.com hardware.
107 #
108 # CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default
109 # on I686_CPU and above.
110 # CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
111 #
112 # CPU_FASTER_5X86_FPU enables faster FPU exception handler.
113 #
114 # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
115 # for i386 machines.
116 #
117 # CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
118 # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
119 # (no clock delay).
120 #
121 # CPU_L2_LATENCY specifed the L2 cache latency value. This option is used
122 # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
123 # The default value is 5.
124 #
125 # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
126 # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
127 # 1).
128 #
129 # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
130 # is useful when you use Socket 8 to Socket 370 converter, because most Pentium
131 # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
132 #
133 # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
134 #
135 # CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
136 # enters suspend mode following execution of HALT instruction.
137 #
138 # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
139 #
140 # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
141 # K5/K6/K6-2 cpus.
142 #
143 # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
144 # flush at hold state.
145 #
146 # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
147 # without cache flush at hold state, and (2) write-back CPU cache on
148 # Cyrix 6x86 whose revision < 2.7 (NOTE 2).
149 #
150 # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
151 # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
152 # executed. This option is only needed if I586_CPU is also defined,
153 # and should be included for any non-Pentium CPU that defines it.
154 #
155 # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
156 # which indicates that the 15-16MB range is *definitely* not being
157 # occupied by an ISA memory hole.
158 #
159 # CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
160 # machines. VmWare seems to emulate this instruction poorly, causing
161 # the guest OS to run very slowly. Enabling this with a SMP kernel
162 # will cause the kernel to be unusable.
163 #
164 # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
165 # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
166 # These options may crash your system.
167 #
168 # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
169 # in write-through mode when revision < 2.7. If revision of Cyrix
170 # 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

217 # DEVICE_POLLING adds support for mixed interrupt-polling handling
218 # of network device drivers, which has significant benefits in terms
219 # of robustness to overloads and responsivity, as well as permitting
220 # accurate scheduling of the CPU time between kernel network processing
221 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
222 # potential increase in response times.
223 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
224 # to achieve smoother behaviour.

277 # This option breaks suspend/resume on some portables.
278 #
279 # AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

628 # The video spigot is at 0xad6. This port address can not be changed.
629 # The irq values may only be 10, 11, or 15
630 # I/O memory is an 8kb region. Possible values are:
631 # 0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff

638 # Notes on the Specialix SI/XIO driver:

644 # Notes on the Sony Programmable I/O controller
645 # This is a temporary driver that should someday be replaced by something
646 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
647 # General Device 10 decoder, which means you have to fiddle with PCI
648 # registers to map it in, even though it is otherwise treated here as
649 # an ISA device. At the moment, the driver polls, although the device
650 # is capable of generating interrupts. It largely undocumented.
651 # The port location in the hint is where you WANT the device to be
652 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
653 # is the only thing truly supported, but aparently a fair percentage
654 # of the Vaio extra features are controlled by this device.

656 # Notes on the Stallion stl and stli drivers:
657 # See src/i386/isa/README.stl for complete instructions.
658 # This is version 0.0.5alpha, unsupported by Stallion.
659 # The stl driver has a secondary IO port hard coded at 0x280. You need
660 # to change src/i386/isa/stallion.c if you reconfigure this on the boards.
661 # The "flags" and "msize" settings on the stli driver depend on the board:
662 # EasyConnection 8/64 ISA: flags 23 msize 0x1000
