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#    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.
159#

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

261#
262# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
263# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
264# This option breaks suspend/resume on some portables.
265#
266# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
267# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
268# Automatic EOI is documented not to work for for the slave with the
269# original i8259A, but it works for some clones and some integrated
270# versions.
271#
272# MAXMEM specifies the amount of RAM on the machine; if this is not
273# specified, FreeBSD will first read the amount of memory from the CMOS
274# RAM, so the amount of memory will initially be limited to 64MB or 16MB
275# depending on the BIOS.  If the BIOS reports 64MB, a memory probe will
276# then attempt to detect the installed amount of RAM.  If this probe
277# fails to detect >64MB RAM you will have to use the MAXMEM option.
278# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
279# be 131072 (128 * 1024).

598#  The flags takes the following meaning for apm0:
599#    0x0020  Statclock is broken.
600#  If apm is omitted, some systems require sysctl kern.timecounter.method=1
601#  for correct timekeeping.
602
603# Notes on the spigot:
604#  The video spigot is at 0xad6.  This port address can not be changed.
605#  The irq values may only be 10, 11, or 15
606#  I/O memory is an 8kb region.  Possible values are:
607#    0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
608#    The start address must be on an even boundary.
609#  Add the following option if you want to allow non-root users to be able
610#  to access the spigot.  This option is not secure because it allows users
611#  direct access to the I/O page.
612#  	options SPIGOT_UNSECURE
613
614# Notes on the Specialix SI/XIO driver:
615#  The host card is memory, not IO mapped.
616#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
617#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
618#  The cards can use an IRQ of 11, 12 or 15.
619
620# Notes on the Sony Programmable I/O controller
621#  This is a temporary driver that should someday be replaced by something
622#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
623#  General Device 10 decoder, which means you have to fiddle with PCI
624#  registers to map it in, even though it is otherwise treated here as
625#  an ISA device. At the moment, the driver polls, although the device
626#  is capable of generating interrupts. It largely undocumented.
627#  The port location in the hint is where you WANT the device to be
628#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
629#  is the only thing truly supported, but aparently a fair percentage
630#  of the Vaio extra features are controlled by this device.
631
632# Notes on the Stallion stl and stli drivers:
633#  See src/i386/isa/README.stl for complete instructions.
634#  This is version 0.0.5alpha, unsupported by Stallion.
635#  The stl driver has a secondary IO port hard coded at 0x280.  You need
636#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
637#  The "flags" and "msize" settings on the stli driver depend on the board:
638#	EasyConnection 8/64 ISA:     flags 23         msize 0x1000
639#	EasyConnection 8/64 EISA:    flags 24         msize 0x10000
640#	EasyConnection 8/64 MCA:     flags 25         msize 0x1000
641#	ONboard ISA:                 flags 4          msize 0x10000
642#	ONboard EISA:                flags 7          msize 0x10000
643#	ONboard MCA:                 flags 3          msize 0x10000
644#	Brumby:                      flags 2          msize 0x4000
645#	Stallion:                    flags 1          msize 0x10000
646
647# Notes on the Digiboard PC/Xi and PC/Xe series driver
648#
649# The NDGBPORTS option specifies the number of ports controlled by the
650# dgb(4) driver.  The default value is 16 ports per device.
651#
652# The following flag values have special meanings in dgb:
