23# Notes:
24#
25#  An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard.
26#
27#  Be sure to disable 'cpu I386_CPU' && 'cpu I486_CPU' for SMP kernels.

48# CPU OPTIONS

50#
51# You must specify at least one CPU (the one you intend to run on);
52# deleting the specification for CPUs you don't need to use may make
53# parts of the system run faster.
54# I386_CPU is mutually exclusive with the other CPU types.

61#
62# Options for CPU features.
63#
64# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
65# forgotten to enable them.
66#
67# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
68# BlueLightning CPU.  It works only with Cyrix FPU, and this option
69# should not be used with Intel FPU.
70#
71# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
72# CPU if CPU supports it. The default is double-clock mode on
73# BlueLightning CPU box.
74#
75# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
76#
77# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
78# mapped mode.  Default is 2-way set associative mode.
79#
80# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
81# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
82# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
83#
84# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
85# reorder).  This option should not be used if you use memory mapped
86# I/O device(s).
87#
88# CPU_ELAN enables support for AMDs ElanSC520 CPU.
89#
90# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.  This is default
91# on I686_CPU and above.
92# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
93#
94# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
95#
96# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
97# for i386 machines.
98#
99# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
100# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
101# (no clock delay).
102#
103# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
104# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
105# The default value is 5.
106#
107# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
108# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
109# 1).
110#
111# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
112# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
113# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
114#
115# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
116#
117# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
118# enters suspend mode following execution of HALT instruction.
119#
120# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
121#
122# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
123# K5/K6/K6-2 cpus.
124#
125# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
126# flush at hold state.
127#
128# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
129# without cache flush at hold state, and (2) write-back CPU cache on
130# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
131#
132# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
133# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
134# executed.  This option is only needed if I586_CPU is also defined,
135# and should be included for any non-Pentium CPU that defines it.
136#
137# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
138# which indicates that the 15-16MB range is *definitely* not being
139# occupied by an ISA memory hole.
140#
141# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
142# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
143# These options may crash your system.
144#
145# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
146# in write-through mode when revision < 2.7.  If revision of Cyrix
147# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
148#

150# locked cycles in order to operate correctly.

194# NETWORKING OPTIONS
195
196#
197# DEVICE_POLLING adds support for mixed interrupt-polling handling
198# of network device drivers, which has significant benefits in terms
199# of robustness to overloads and responsivity, as well as permitting
200# accurate scheduling of the CPU time between kernel network processing
201# and other activities. The drawback is a moderate (up to 1/HZ seconds)
202# potential increase in response times.
203# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
204# to achieve smoother behaviour.
205# Additionally, you can enable/disable polling at runtime with the
206# sysctl variable kern.polling.enable (defaults off), and select
207# the CPU fraction reserved to userland with the sysctl variable
208# kern.polling.user_frac (default 50, range 0..100).

253# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
254# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
255# This option breaks suspend/resume on some portables.
256#
257# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
258# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
259# Automatic EOI is documented not to work for for the slave with the
260# original i8259A, but it works for some clones and some integrated
261# versions.
262#
263# MAXMEM specifies the amount of RAM on the machine; if this is not
264# specified, FreeBSD will first read the amount of memory from the CMOS
265# RAM, so the amount of memory will initially be limited to 64MB or 16MB
266# depending on the BIOS.  If the BIOS reports 64MB, a memory probe will
267# then attempt to detect the installed amount of RAM.  If this probe
268# fails to detect >64MB RAM you will have to use the MAXMEM option.
269# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
270# be 131072 (128 * 1024).
271#
272# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to

530#  The host card is memory, not IO mapped.
531#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.

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

547# Notes on the Stallion stl and stli drivers:
548#  See src/i386/isa/README.stl for complete instructions.
549#  This is version 0.0.5alpha, unsupported by Stallion.
550#  The stl driver has a secondary IO port hard coded at 0x280.  You need
551#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
552#  The "flags" and "msize" settings on the stli driver depend on the board:

554#	EasyConnection 8/64 EISA:    flags 24         msize 0x10000
