55 # You must specify at least one CPU (the one you intend to run on);
56 # deleting the specification for CPUs you don't need to use may make
57 # parts of the system run faster.
58 # I386_CPU is mutually exclusive with the other CPU types.

66 # Options for CPU features.
67 #
68 # CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
69 # forgotten to enable them.
70 #
71 # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
72 # BlueLightning CPU. It works only with Cyrix FPU, and this option
73 # should not be used with Intel FPU.
74 #
75 # CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
76 # CPU if CPU supports it. The default is double-clock mode on
77 # BlueLightning CPU box.
78 #
79 # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
80 #
81 # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
82 # mapped mode. Default is 2-way set associative mode.
83 #
84 # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
85 # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
86 # Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
87 #
88 # CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
89 # reorder). This option should not be used if you use memory mapped
90 # I/O device(s).
91 #
92 # CPU_ELAN enables support for AMDs ElanSC520 CPU.
93 # ELAN_XTAL sets the clock crystal frequency in Hz
94 # ELAN_PPS enables precision timestamp code.
95 #
96 # CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default
97 # on I686_CPU and above.
98 # CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
99 #
100 # CPU_FASTER_5X86_FPU enables faster FPU exception handler.
101 #
102 # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
103 # for i386 machines.
104 #
105 # CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
106 # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
107 # (no clock delay).
108 #
109 # CPU_L2_LATENCY specifed the L2 cache latency value. This option is used
110 # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
111 # The default value is 5.
112 #
113 # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
114 # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
115 # 1).
116 #
117 # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
118 # is useful when you use Socket 8 to Socket 370 converter, because most Pentium
119 # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
120 #
121 # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
122 #
123 # CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
124 # enters suspend mode following execution of HALT instruction.
125 #
126 # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
127 #
128 # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
129 # K5/K6/K6-2 cpus.
130 #
131 # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
132 # flush at hold state.
133 #
134 # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
135 # without cache flush at hold state, and (2) write-back CPU cache on
136 # Cyrix 6x86 whose revision < 2.7 (NOTE 2).
137 #
138 # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
139 # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
140 # executed. This option is only needed if I586_CPU is also defined,
141 # and should be included for any non-Pentium CPU that defines it.
142 #
143 # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
144 # which indicates that the 15-16MB range is *definitely* not being
145 # occupied by an ISA memory hole.
146 #
147 # CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
148 # machines. VmWare seems to emulate this instruction poorly, causing
149 # the guest OS to run very slowly. Enabling this with a SMP kernel
150 # will cause the kernel to be unusable.
151 #
152 # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
153 # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
154 # These options may crash your system.
155 #
156 # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
157 # in write-through mode when revision < 2.7. If revision of Cyrix
158 # 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

215 # of network device drivers, which has significant benefits in terms
216 # of robustness to overloads and responsivity, as well as permitting
217 # accurate scheduling of the CPU time between kernel network processing
218 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
219 # potential increase in response times.
220 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
221 # to achieve smoother behaviour.
222 # Additionally, you can enable/disable polling at runtime with the
223 # sysctl variable kern.polling.enable (defaults off), and select

273 # interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
274 # This option breaks suspend/resume on some portables.
275 #
276 # AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
277 # interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
278 # Automatic EOI is documented not to work for for the slave with the

280 # versions.
281 #
282 # MAXMEM specifies the amount of RAM on the machine; if this is not
283 # specified, FreeBSD will first read the amount of memory from the CMOS
284 # RAM, so the amount of memory will initially be limited to 64MB or 16MB
285 # depending on the BIOS. If the BIOS reports 64MB, a memory probe will
286 # then attempt to detect the installed amount of RAM. If this probe

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

635 # See src/i386/isa/README.stl for complete instructions.
636 # This is version 0.0.5alpha, unsupported by Stallion.
637 # The stl driver has a secondary IO port hard coded at 0x280. You need
638 # to change src/i386/isa/stallion.c if you reconfigure this on the boards.
639 # The "flags" and "msize" settings on the stli driver depend on the board:
640 # EasyConnection 8/64 ISA: flags 23 msize 0x1000
641 # EasyConnection 8/64 EISA: flags 24 msize 0x10000

649 # Notes on the Digiboard PC/Xi and PC/Xe series driver
650 #
651 # The NDGBPORTS option specifies the number of ports controlled by the
652 # dgb(4) driver. The default value is 16 ports per device.
