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.

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

67# Certain applications can grow to be larger than the 512M limit
68# that FreeBSD initially imposes.  Below are some options to
69# allow that limit to grow to 1GB, and can be increased further
70# with changing the parameters.  MAXDSIZ is the maximum that the
71# limit can be set to, and the DFLDSIZ is the default value for
72# the limit.  MAXSSIZ is the maximum that the stack limit can be
73# set to.  You might want to set the default lower than the max,
74# and explicitly set the maximum with a shell command for processes
75# that regularly exceed the limit like INND.

83# device I/O.  Note that this value will be overriden by the label
84# when specifying a block device from a label with a non-0

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

172
173#
174# Options for CPU features.
175#
176# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
177# BlueLightning CPU.  It works only with Cyrix FPU, and this option
178# should not be used with Intel FPU.
179#
180# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
181# CPU if CPU supports it. The default is double-clock mode on
182# BlueLightning CPU box.
183#
184# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
185#
186# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
187# mapped mode.  Default is 2-way set associative mode.
188#
189# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
190# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
191# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
192#
193# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
194# reorder).  This option should not be used if you use memory mapped
195# I/O device(s).
196#
197# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.
198#
199# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
200#
201# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
202# for i386 machines.
203#
204# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
205# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
206# (no clock delay).
207#
208# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
209# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
210# The default value is 5.
211#
212# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
213# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
214# 1).
215#
216# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
217# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
218# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
219#
220# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
221#
222# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
223# enters suspend mode following execution of HALT instruction.
224#
225# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
226#
227# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
228# K5/K6/K6-2 cpus.
229#
230# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
231# flush at hold state.
232#
233# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
234# without cache flush at hold state, and (2) write-back CPU cache on
235# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
236#
237# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
238# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
239# executed.  This option is only needed if I586_CPU is also defined,
240# and should be included for any non-Pentium CPU that defines it.
241#
242# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
243# which indicates that the 15-16MB range is *definitely* not being
244# occupied by an ISA memory hole.
245#
246# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
247# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
248# These options may crash your system.
249#
250# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
251# in write-through mode when revision < 2.7.  If revision of Cyrix
252# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
253#

339# KTR is a kernel tracing mechanism imported from BSD/OS.  Currently it
340# has no userland interface aside from a few sysctl's.  It is enabled with
341# the KTR option.  The KTR_EXTEND option causes trace events to be generated
342# as a string from snprintf rather than as a string and up to 5 argument
343# pointers.  KTR_ENTRIES defines the number of entries in the circular trace
344# buffer.  KTR_COMPILE defines the mask of events to compile into the kernel
345# as defined by the KTR_* constants in <sys/ktr.h>.  KTR_MASK defines the
346# initial value of the ktr_mask variable which determines at runtime what
347# events to trace.  KTR_CPUMASK determines which CPU's log events, with
348# bit X corresponding to cpu X.  KTR_VERBOSE enables dumping of KTR events
349# to the console by default.  This functionality can be toggled via the
350# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined.

373# called.  The intent is that you can set 'INVARIANTS' for single
374# source files (by changing the source file or specifying it on the
375# command line) if you have 'INVARIANT_SUPPORT' enabled.  Also, if you
376# wish to build a kernel module with 'INVARIANTS', then adding

850# SCSI DEVICES
851
852# SCSI DEVICE CONFIGURATION
853
854# The SCSI subsystem consists of the `base' SCSI code, a number of
855# high-level SCSI device `type' drivers, and the low-level host-adapter
856# device drivers.  The host adapters are listed in the ISA and PCI
857# device configuration sections below.
858#
859# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
860# that a given bus, target, and LUN always come on line as the same
861# device unit.  In earlier versions the unit numbers were assigned
862# in the order that the devices were probed on the SCSI bus.  This
863# means that if you removed a disk drive, you may have had to rewrite
864# your /etc/fstab file, and also that you had to be careful when adding
865# a new disk as it may have been probed earlier and moved your device
866# configuration around.
867
868# This old behavior is maintained as the default behavior.  The unit
869# assignment begins with the first non-wired down unit for a device
870# type.  For example, if you wire a disk as "da3" then the first
871# non-wired disk will be assigned da4.
872
873# The syntax for wiring down devices is:
874

1476# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1477# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1478# The DPT controllers are commonly re-licensed under other brand-names -
1479# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1480# Compaq are actually DPT controllers.
1481#
1482# See src/sys/dev/dpt for debugging and other subtle options.
1483#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1484#                           instruments are enabled.  The tools in
1485#                           /usr/sbin/dpt_* assume these to be enabled.
1486#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1487#                           If you ant the driver to handle timeouts, enable
1488#                           this option.  If your system is very busy, this
1489#                           option will create more trouble than solve.
1490#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
1491#                           wait when timing out with the above option.
1492#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
1493#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
1494#                           any interrupt that got lost.  Seems to help in some
1495#                           DPT-firmware/Motherboard combinations.  Minimal
1496#                           cost, great benefit.
1497#  DPT_RESET_HBA            Make "reset" actually reset the controller
1498#                           instead of fudging it.  Only enable this if you

2105#	0x02 - use the windowed PC/Xe in 64K mode
2106
2107# Notes on the Specialix SI/XIO driver:
2108#  The host card is memory, not IO mapped.
2109#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2110#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2111#  The cards can use an IRQ of 11, 12 or 15.
2112
2113# Notes on the Sony Programmable I/O controller
2114#  This is a temporary driver that should someday be replaced by something
2115#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
2116#  General Device 10 decoder, which means you have to fiddle with PCI
2117#  registers to map it in, even though it is otherwise treated here as
2118#  an ISA device. At the moment, the driver polls, although the device
2119#  is capable of generating interrupts. It largely undocumented.
2120#  The port location in the hint is where you WANT the device to be
2121#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2122#  is the only thing truly supported, but aparently a fair percentage
2123#  of the Vaio extra features are controlled by this device.
2124
2125# Notes on the Stallion stl and stli drivers:
2126#  See src/i386/isa/README.stl for complete instructions.
2127#  This is version 0.0.5alpha, unsupported by Stallion.
2128#  The stl driver has a secondary IO port hard coded at 0x280.  You need
2129#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2130#  The "flags" and "msize" settings on the stli driver depend on the board:
