2# NOTES -- Lines that can be cut/pasted into kernel and hints configs.
3#
4# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
5# 'makeoptions', 'hints' etc go into the kernel configuration that you
6# run config(8) with.
7#
8# Lines that begin with 'hints.' are NOT for config(8), they go into your
9# hints file.  See /boot/device.hints and/or the 'hints' config(8) directive.
10#
11# Please use ``make LINT'' to create an old-style LINT file if you want to
12# do kernel test-builds.

31# The `maxusers' parameter controls the static sizing of a number of
32# internal system tables by a formula defined in subr_param.c.  Setting
33# maxusers to 0 will cause the system to auto-size based on physical
34# memory.

43# The `makeoptions' parameter allows variables to be passed to the
44# generated Makefile in the build area.
45#
46# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
47# after most other flags.  Here we use it to inhibit use of non-optimal
48# gcc builtin functions (e.g., memcmp).
49#
50# DEBUG happens to be magic.
51# The following is equivalent to 'config -g KERNELNAME' and creates
52# 'kernel.debug' compiled with -g debugging as well as a normal
53# 'kernel'.  Use 'make install.debug' to install the debug kernel
54# but that isn't normally necessary as the debug symbols are not loaded
55# by the kernel and are not useful there anyway.
56#
57# KERNEL can be overridden so that you can change the default name of your
58# kernel.
59#
60# MODULES_OVERRIDE can be used to limit modules built to a specific list.

70# that FreeBSD initially imposes.  Below are some options to
71# allow that limit to grow to 1GB, and can be increased further
72# with changing the parameters.  MAXDSIZ is the maximum that the
73# limit can be set to, and the DFLDSIZ is the default value for
74# the limit.  MAXSSIZ is the maximum that the stack limit can be
75# set to.  You might want to set the default lower than the max,
76# and explicitly set the maximum with a shell command for processes
77# that regularly exceed the limit like INND.

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

175#
176# Options for CPU features.
177#
178# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
179# BlueLightning CPU.  It works only with Cyrix FPU, and this option
180# should not be used with Intel FPU.
181#
182# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
183# CPU if CPU supports it. The default is double-clock mode on
184# BlueLightning CPU box.
185#
186# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
187#
188# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
189# mapped mode.  Default is 2-way set associative mode.
190#
191# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
192# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
193# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
194#
195# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
196# reorder).  This option should not be used if you use memory mapped
197# I/O device(s).
198#
199# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.
200#
201# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
202#
203# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
204# for i386 machines.
205#
206# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
207# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
208# (no clock delay).
209#
210# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
211# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
212# The default value is 5.
213#
214# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
215# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
216# 1).
217#
218# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
219# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
220# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
221#
222# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
223#
224# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
225# enters suspend mode following execution of HALT instruction.
226#
227# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
228#
229# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
230# K5/K6/K6-2 cpus.
231#
232# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
233# flush at hold state.
234#
235# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
236# without cache flush at hold state, and (2) write-back CPU cache on
237# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
238#
239# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
240# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
241# executed.  This option is only needed if I586_CPU is also defined,
242# and should be included for any non-Pentium CPU that defines it.
243#
244# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
245# which indicates that the 15-16MB range is *definitely* not being
246# occupied by an ISA memory hole.
247#
248# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
249# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
250# These options may crash your system.
251#
252# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
253# in write-through mode when revision < 2.7.  If revision of Cyrix
254# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

343# the KTR option.  The KTR_EXTEND option causes trace events to be generated
344# as a string from snprintf rather than as a string and up to 5 argument
345# pointers.  KTR_ENTRIES defines the number of entries in the circular trace
346# buffer.  KTR_COMPILE defines the mask of events to compile into the kernel
347# as defined by the KTR_* constants in <sys/ktr.h>.  KTR_MASK defines the
348# initial value of the ktr_mask variable which determines at runtime what
349# events to trace.  KTR_CPUMASK determines which CPU's log events, with
350# bit X corresponding to cpu X.  KTR_VERBOSE enables dumping of KTR events
351# to the console by default.  This functionality can be toggled via the
352# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined.

376# source files (by changing the source file or specifying it on the
377# command line) if you have 'INVARIANT_SUPPORT' enabled.  Also, if you
378# wish to build a kernel module with 'INVARIANTS', then adding

878
879# SCSI DEVICE CONFIGURATION
880
881# The SCSI subsystem consists of the `base' SCSI code, a number of
882# high-level SCSI device `type' drivers, and the low-level host-adapter
883# device drivers.  The host adapters are listed in the ISA and PCI
884# device configuration sections below.
885#
886# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
887# that a given bus, target, and LUN always come on line as the same
888# device unit.  In earlier versions the unit numbers were assigned
889# in the order that the devices were probed on the SCSI bus.  This
890# means that if you removed a disk drive, you may have had to rewrite
891# your /etc/fstab file, and also that you had to be careful when adding
892# a new disk as it may have been probed earlier and moved your device
893# configuration around.
894
895# This old behavior is maintained as the default behavior.  The unit
896# assignment begins with the first non-wired down unit for a device
897# type.  For example, if you wire a disk as "da3" then the first
898# non-wired disk will be assigned da4.
899
900# The syntax for wiring down devices is:

1507# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1508# Compaq are actually DPT controllers.
1509#
1510# See src/sys/dev/dpt for debugging and other subtle options.
1511#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1512#                           instruments are enabled.  The tools in
1513#                           /usr/sbin/dpt_* assume these to be enabled.
1514#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1515#                           If you ant the driver to handle timeouts, enable
1516#                           this option.  If your system is very busy, this
1517#                           option will create more trouble than solve.

2135# Notes on the Specialix SI/XIO driver:
2136#  The host card is memory, not IO mapped.
2137#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2138#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.

2141# Notes on the Sony Programmable I/O controller
2142#  This is a temporary driver that should someday be replaced by something
2143#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
2144#  General Device 10 decoder, which means you have to fiddle with PCI
2145#  registers to map it in, even though it is otherwise treated here as
2146#  an ISA device. At the moment, the driver polls, although the device
2147#  is capable of generating interrupts. It largely undocumented.
2148#  The port location in the hint is where you WANT the device to be
2149#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2150#  is the only thing truly supported, but aparently a fair percentage
2151#  of the Vaio extra features are controlled by this device.
2152
2153# Notes on the Stallion stl and stli drivers:
2154#  See src/i386/isa/README.stl for complete instructions.
2155#  This is version 0.0.5alpha, unsupported by Stallion.
2156#  The stl driver has a secondary IO port hard coded at 0x280.  You need
2157#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2158#  The "flags" and "msize" settings on the stli driver depend on the board:
