52# CPU OPTIONS

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.

65#
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#
94# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.  This is default
95# on I686_CPU and above.
96# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
97#
98# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
99#
100# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
101# for i386 machines.
102#
103# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
104# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
105# (no clock delay).
106#
107# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
108# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
109# The default value is 5.
110#
111# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
112# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
113# 1).
114#
115# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
116# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
117# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
118#
119# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
120#
121# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
122# enters suspend mode following execution of HALT instruction.
123#
124# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
125#
126# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
127# K5/K6/K6-2 cpus.
128#
129# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
130# flush at hold state.
131#
132# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
133# without cache flush at hold state, and (2) write-back CPU cache on
134# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
135#
136# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
137# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
138# executed.  This option is only needed if I586_CPU is also defined,
139# and should be included for any non-Pentium CPU that defines it.
140#
141# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
142# which indicates that the 15-16MB range is *definitely* not being
143# occupied by an ISA memory hole.
144#
145# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
146# machines.  VmWare seems to emulate this instruction poorly, causing
147# the guest OS to run very slowly.  Enabling this with a SMP kernel
148# will cause the kernel to be unusable.
149#
150# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
151# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
152# These options may crash your system.
153#
154# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
155# in write-through mode when revision < 2.7.  If revision of Cyrix
156# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
157#

207# DEVICE_POLLING adds support for mixed interrupt-polling handling
208# of network device drivers, which has significant benefits in terms
209# of robustness to overloads and responsivity, as well as permitting
210# accurate scheduling of the CPU time between kernel network processing
211# and other activities. The drawback is a moderate (up to 1/HZ seconds)
212# potential increase in response times.
213# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
214# to achieve smoother behaviour.
215# Additionally, you can enable/disable polling at runtime with the
216# sysctl variable kern.polling.enable (defaults off), and select
217# the CPU fraction reserved to userland with the sysctl variable
218# kern.polling.user_frac (default 50, range 0..100).

263# Options for `isa':
264#
265# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
266# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
267# This option breaks suspend/resume on some portables.
268#
269# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
270# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
271# Automatic EOI is documented not to work for for the slave with the
272# original i8259A, but it works for some clones and some integrated
273# versions.
274#
275# MAXMEM specifies the amount of RAM on the machine; if this is not
276# specified, FreeBSD will first read the amount of memory from the CMOS
277# RAM, so the amount of memory will initially be limited to 64MB or 16MB
278# depending on the BIOS.  If the BIOS reports 64MB, a memory probe will
279# then attempt to detect the installed amount of RAM.  If this probe
280# fails to detect >64MB RAM you will have to use the MAXMEM option.
281# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
282# be 131072 (128 * 1024).
283#

604#  to access the spigot.  This option is not secure because it allows users
605#  direct access to the I/O page.
606#  	options SPIGOT_UNSECURE

608# Notes on the Specialix SI/XIO driver:
609#  The host card is memory, not IO mapped.
610#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
611#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
612#  The cards can use an IRQ of 11, 12 or 15.
613
614# Notes on the Sony Programmable I/O controller
615#  This is a temporary driver that should someday be replaced by something
616#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
617#  General Device 10 decoder, which means you have to fiddle with PCI
618#  registers to map it in, even though it is otherwise treated here as
619#  an ISA device. At the moment, the driver polls, although the device
620#  is capable of generating interrupts. It largely undocumented.
621#  The port location in the hint is where you WANT the device to be
622#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
623#  is the only thing truly supported, but aparently a fair percentage
624#  of the Vaio extra features are controlled by this device.
625
626# Notes on the Stallion stl and stli drivers:
627#  See src/i386/isa/README.stl for complete instructions.
628#  This is version 0.0.5alpha, unsupported by Stallion.
629#  The stl driver has a secondary IO port hard coded at 0x280.  You need
630#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
631#  The "flags" and "msize" settings on the stli driver depend on the board:
632#	EasyConnection 8/64 ISA:     flags 23         msize 0x1000
633#	EasyConnection 8/64 EISA:    flags 24         msize 0x10000
634#	EasyConnection 8/64 MCA:     flags 25         msize 0x1000
635#	ONboard ISA:                 flags 4          msize 0x10000
636#	ONboard EISA:                flags 7          msize 0x10000
637#	ONboard MCA:                 flags 3          msize 0x10000

1047# map the kernel.  You should only disable this feature as a temporary
1048# workaround if you are having problems with it enabled.
