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.

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.

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.  MAXSSIZ is the maximum that the stack limit can be
69# set to.  You might want to set the default lower than the max, 
70# and explicitly set the maximum with a shell command for processes
71# that regularly exceed the limit like INND.

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

169#
170# Options for CPU features.
171#
172# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
173# BlueLightning CPU.  It works only with Cyrix FPU, and this option
174# should not be used with Intel FPU.
175#
176# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
177# CPU if CPU supports it. The default is double-clock mode on
178# BlueLightning CPU box.
179#
180# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
181#
182# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
183# mapped mode.  Default is 2-way set associative mode.
184#
185# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
186# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
187# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
188#
189# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
190# reorder).  This option should not be used if you use memory mapped
191# I/O device(s).
192#
193# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.
194#
195# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
196#
197# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
198# for i386 machines.
199#
200# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
201# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
202# (no clock delay).
203#
204# CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
205# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
206# The default value is 5.
207#
208# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
209# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
210# 1).
211#
212# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
213# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
214# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
215#
216# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
217#
218# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
219# enters suspend mode following execution of HALT instruction.
220#
221# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
222# K5/K6/K6-2 cpus.
223#
224# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
225# flush at hold state.
226#
227# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
228# without cache flush at hold state, and (2) write-back CPU cache on
229# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
230#
231# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
232# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
233# executed.  This option is only needed if I586_CPU is also defined,
234# and should be included for any non-Pentium CPU that defines it.
235#
236# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
237# which indicates that the 15-16MB range is *definitely* not being
238# occupied by an ISA memory hole.
239#
240# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
241# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
242# These options may crash your system.
243#
244# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
245# in write-through mode when revision < 2.7.  If revision of Cyrix
246# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

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

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

841# SCSI DEVICES
842
843# SCSI DEVICE CONFIGURATION
844
845# The SCSI subsystem consists of the `base' SCSI code, a number of
846# high-level SCSI device `type' drivers, and the low-level host-adapter
847# device drivers.  The host adapters are listed in the ISA and PCI
848# device configuration sections below.
849#
850# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
851# that a given bus, target, and LUN always come on line as the same
852# device unit.  In earlier versions the unit numbers were assigned
853# in the order that the devices were probed on the SCSI bus.  This
854# means that if you removed a disk drive, you may have had to rewrite
855# your /etc/fstab file, and also that you had to be careful when adding
856# a new disk as it may have been probed earlier and moved your device
857# configuration around.
858
859# This old behavior is maintained as the default behavior.  The unit
860# assignment begins with the first non-wired down unit for a device
861# type.  For example, if you wire a disk as "da3" then the first
862# non-wired disk will be assigned da4.
863
864# The syntax for wiring down devices is:
865

2066# Notes on the Specialix SI/XIO driver:
2067#  The host card is memory, not IO mapped.
2068#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2069#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2070#  The cards can use an IRQ of 11, 12 or 15.
2071
2072# Notes on the Sony Programmable I/O controller
2073#  This is a temporary driver that should someday be replaced by something
2074#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
2075#  General Device 10 decoder, which means you have to fiddle with PCI
2076#  registers to map it in, even though it is otherwise treated here as
2077#  an ISA device. At the moment, the driver polls, although the device
2078#  is capable of generating interrupts. It largely undocumented.
2079#  The port location in the hint is where you WANT the device to be
2080#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2081#  is the only thing truly supported, but aparently a fair percentage
2082#  of the Vaio extra features are controlled by this device.
2083
2084# Notes on the Stallion stl and stli drivers:
2085#  See src/i386/isa/README.stl for complete instructions.
2086#  This is version 0.0.5alpha, unsupported by Stallion.
2087#  The stl driver has a secondary IO port hard coded at 0x280.  You need
2088#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2089#  The "flags" and "msize" settings on the stli driver depend on the board:
2090#	EasyConnection 8/64 ISA:     flags 23         msize 0x1000
