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.

11# Please use ``make LINT'' to create an old-style LINT file if you want to
12# do kernel test-builds.

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.

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

155#
156# You must specify at least one CPU (the one you intend to run on);
157# deleting the specification for CPUs you don't need to use may make
158# parts of the system run faster.
159# I386_CPU is mutually exclusive with the other CPU types.

165
166#
167# Options for CPU features.
168#
169# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
170# BlueLightning CPU.  It works only with Cyrix FPU, and this option
171# should not be used with Intel FPU.
172#
173# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
174# CPU if CPU supports it. The default is double-clock mode on
175# BlueLightning CPU box.
176#
177# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
178#
179# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
180# mapped mode.  Default is 2-way set associative mode.
181#
182# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
183# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
184# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
185#
186# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
187# reorder).  This option should not be used if you use memory mapped
188# I/O device(s).
189#
190# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
191#
192# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
193# for i386 machines.
194#
195# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
196# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
197# (no clock delay).
198#
199# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
200# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
201# The default value is 5.
202#
203# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
204# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
205# 1).
206#
207# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
208# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
209# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
210#
211# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
212#
213# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
214# enters suspend mode following execution of HALT instruction.
215#
216# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
217# K5/K6/K6-2 cpus.
218#
219# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
220# flush at hold state.
221#
222# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
223# without cache flush at hold state, and (2) write-back CPU cache on
224# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
225#
226# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
227# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
228# executed.  This option is only needed if I586_CPU is also defined,
229# and should be included for any non-Pentium CPU that defines it.
230#
231# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
232# which indicates that the 15-16MB range is *definitely* not being
233# occupied by an ISA memory hole.
234#
235# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
236# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
237# These options may crash your system.
238#
239# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
240# in write-through mode when revision < 2.7.  If revision of Cyrix
241# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

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

348# The INVARIANTS option is used in a number of source files to enable
349# extra sanity checking of internal structures.  This support is not

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

811# SCSI DEVICES
812
813# SCSI DEVICE CONFIGURATION
814
815# The SCSI subsystem consists of the `base' SCSI code, a number of
816# high-level SCSI device `type' drivers, and the low-level host-adapter
817# device drivers.  The host adapters are listed in the ISA and PCI
818# device configuration sections below.
819#
820# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
821# that a given bus, target, and LUN always come on line as the same
822# device unit.  In earlier versions the unit numbers were assigned
823# in the order that the devices were probed on the SCSI bus.  This
824# means that if you removed a disk drive, you may have had to rewrite
825# your /etc/fstab file, and also that you had to be careful when adding
826# a new disk as it may have been probed earlier and moved your device
827# configuration around.
828
829# This old behavior is maintained as the default behavior.  The unit
830# assignment begins with the first non-wired down unit for a device
831# type.  For example, if you wire a disk as "da3" then the first
832# non-wired disk will be assigned da4.
833
834# The syntax for wiring down devices is:
835
836hint.scbus.0.at="ahc0"
837hint.scbus.1.at="ahc1"

879# of the command support might be done in /usr/share/examples/scsi_target.

1979#   If instead you have two ISA cards, one installed at 0x100 and the

2002#	0x01 - alternate layout of pins (dgb & dgm)
2003#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
2004
2005# Notes on the Specialix SI/XIO driver:
2006#  The host card is memory, not IO mapped.
2007#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2008#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.

2010
2011# Notes on the Sony Programmable I/O controller
2012#  This is a temporary driver that should someday be replaced by something
2013#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
2014#  General Device 10 decoder, which means you have to fiddle with PCI
2015#  registers to map it in, even though it is otherwise treated here as
2016#  an ISA device. At the moment, the driver polls, although the device
2017#  is capable of generating interrupts. It largely undocumented.
2018#  The port location in the hint is where you WANT the device to be
2019#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2020#  is the only thing truly supported, but aparently a fair percentage
2021#  of the Vaio extra features are controlled by this device.

2025#  This is version 0.0.5alpha, unsupported by Stallion.

2027#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2028#  The "flags" and "msize" settings on the stli driver depend on the board:
