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.

64#
65# You must specify at least one CPU (the one you intend to run on);
66# deleting the specification for CPUs you don't need to use may make
67# parts of the system run faster.

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_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#    ELAN_XTAL sets the clock crystal frequency in Hz
104#    ELAN_PPS enables precision timestamp code.
105#
106# CPU_SOEKRIS enables support www.soekris.com hardware.
107#    For the 45xx series you can also use ELAN_XTAL and ELAN_PPS options.
108#
109# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.  This is default
110# on I686_CPU and above.
111# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
112#
113# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
114#
115# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
116# for i386 machines.
117#
118# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
119# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
120# (no clock delay).
121#
122# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
123# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
124# The default value is 5.
125#
126# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
127# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
128# 1).
129#
130# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
131# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
132# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
133#
134# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
135#
136# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
137# enters suspend mode following execution of HALT instruction.
138#
139# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
140#
141# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
142# K5/K6/K6-2 cpus.
143#
144# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
145# flush at hold state.
146#
147# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
148# without cache flush at hold state, and (2) write-back CPU cache on
149# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
150#
151# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
152# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
153# executed.  This option is only needed if I586_CPU is also defined,
154# and should be included for any non-Pentium CPU that defines it.
155#
156# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
157# which indicates that the 15-16MB range is *definitely* not being
158# occupied by an ISA memory hole.
159#
160# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
161# machines.  VmWare seems to emulate this instruction poorly, causing
162# the guest OS to run very slowly.  Enabling this with a SMP kernel
163# will cause the kernel to be unusable.
164#
165# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
166# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
167# These options may crash your system.
168#
169# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
170# in write-through mode when revision < 2.7.  If revision of Cyrix
171# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
172#
173# NOTE 3: This option may cause failures for software that requires
174# locked cycles in order to operate correctly.

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

274# Options for `isa':
275#
276# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
277# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
278# This option breaks suspend/resume on some portables.
279#
280# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
281# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
282# Automatic EOI is documented not to work for for the slave with the
283# original i8259A, but it works for some clones and some integrated
284# versions.
285#
286# MAXMEM specifies the amount of RAM on the machine; if this is not
287# specified, FreeBSD will first read the amount of memory from the CMOS
288# RAM, so the amount of memory will initially be limited to 64MB or 16MB
289# depending on the BIOS.  If the BIOS reports 64MB, a memory probe will
290# then attempt to detect the installed amount of RAM.  If this probe
291# fails to detect >64MB RAM you will have to use the MAXMEM option.
292# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
293# be 131072 (128 * 1024).

622# Notes on APM
623#  The flags takes the following meaning for apm0:
624#    0x0020  Statclock is broken.
625#  If apm is omitted, some systems require sysctl kern.timecounter.method=1
626#  for correct timekeeping.
627
628# Notes on the spigot:
629#  The video spigot is at 0xad6.  This port address can not be changed.
630#  The irq values may only be 10, 11, or 15
631#  I/O memory is an 8kb region.  Possible values are:
632#    0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
633#    The start address must be on an even boundary.
634#  Add the following option if you want to allow non-root users to be able
635#  to access the spigot.  This option is not secure because it allows users
636#  direct access to the I/O page.
637#  	options SPIGOT_UNSECURE
638
639# Notes on the Specialix SI/XIO driver:
640#  The host card is memory, not IO mapped.
641#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
642#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
643#  The cards can use an IRQ of 11, 12 or 15.
644
645# Notes on the Sony Programmable I/O controller
646#  This is a temporary driver that should someday be replaced by something
647#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
648#  General Device 10 decoder, which means you have to fiddle with PCI
649#  registers to map it in, even though it is otherwise treated here as
650#  an ISA device. At the moment, the driver polls, although the device
651#  is capable of generating interrupts. It largely undocumented.
652#  The port location in the hint is where you WANT the device to be
653#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
654#  is the only thing truly supported, but aparently a fair percentage
655#  of the Vaio extra features are controlled by this device.
656
657# Notes on the Stallion stl and stli drivers:
658#  See src/i386/isa/README.stl for complete instructions.
659#  This is version 0.0.5alpha, unsupported by Stallion.
660#  The stl driver has a secondary IO port hard coded at 0x280.  You need
661#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
662#  The "flags" and "msize" settings on the stli driver depend on the board:
663#	EasyConnection 8/64 ISA:     flags 23         msize 0x1000
664#	EasyConnection 8/64 EISA:    flags 24         msize 0x10000
665#	EasyConnection 8/64 MCA:     flags 25         msize 0x1000
666#	ONboard ISA:                 flags 4          msize 0x10000
667#	ONboard EISA:                flags 7          msize 0x10000
668#	ONboard MCA:                 flags 3          msize 0x10000
669#	Brumby:                      flags 2          msize 0x4000
670#	Stallion:                    flags 1          msize 0x10000
671
672# Notes on the Digiboard PC/Xi and PC/Xe series driver
673#
674# The NDGBPORTS option specifies the number of ports controlled by the
675# dgb(4) driver.  The default value is 16 ports per device.
676#
677# The following flag values have special meanings in dgb:
678#	0x01 - alternate layout of pins
679#	0x02 - use the windowed PC/Xe in 64K mode

1056# STREAMS device and a dynamically loadable svr4 emulator;  the /usr/sbin/svr4
1057# script understands that it doesn't need to load the `streams' module under
1058# those circumstances.
