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.

168
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_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
222#
223# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
224# K5/K6/K6-2 cpus.
225#
226# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
227# flush at hold state.
228#
229# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
230# without cache flush at hold state, and (2) write-back CPU cache on
231# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
232#
233# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
234# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
235# executed.  This option is only needed if I586_CPU is also defined,
236# and should be included for any non-Pentium CPU that defines it.
237#
238# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
239# which indicates that the 15-16MB range is *definitely* not being
240# occupied by an ISA memory hole.
241#
242# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
243# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
244# These options may crash your system.
245#
246# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
247# in write-through mode when revision < 2.7.  If revision of Cyrix
248# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

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

370# source files (by changing the source file or specifying it on the
371# command line) if you have 'INVARIANT_SUPPORT' enabled.  Also, if you

845# SCSI DEVICES
846
847# SCSI DEVICE CONFIGURATION
848
849# The SCSI subsystem consists of the `base' SCSI code, a number of
850# high-level SCSI device `type' drivers, and the low-level host-adapter
851# device drivers.  The host adapters are listed in the ISA and PCI
852# device configuration sections below.
853#
854# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
855# that a given bus, target, and LUN always come on line as the same
856# device unit.  In earlier versions the unit numbers were assigned
857# in the order that the devices were probed on the SCSI bus.  This
858# means that if you removed a disk drive, you may have had to rewrite
859# your /etc/fstab file, and also that you had to be careful when adding
860# a new disk as it may have been probed earlier and moved your device
861# configuration around.
862
863# This old behavior is maintained as the default behavior.  The unit
864# assignment begins with the first non-wired down unit for a device
865# type.  For example, if you wire a disk as "da3" then the first
866# non-wired disk will be assigned da4.
867
868# The syntax for wiring down devices is:
869
870hint.scbus.0.at="ahc0"

1473# See src/sys/dev/dpt for debugging and other subtle options.
1474#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1475#                           instruments are enabled.  The tools in
1476#                           /usr/sbin/dpt_* assume these to be enabled.
1477#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1478#                           If you ant the driver to handle timeouts, enable
1479#                           this option.  If your system is very busy, this
1480#                           option will create more trouble than solve.
1481#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
1482#                           wait when timing out with the above option.
1483#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
1484#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
1485#                           any interrupt that got lost.  Seems to help in some
1486#                           DPT-firmware/Motherboard combinations.  Minimal
1487#                           cost, great benefit.
1488#  DPT_RESET_HBA            Make "reset" actually reset the controller
1489#                           instead of fudging it.  Only enable this if you

2076# Notes on the Specialix SI/XIO driver:
2077#  The host card is memory, not IO mapped.
2078#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2079#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2080#  The cards can use an IRQ of 11, 12 or 15.
2081
2082# Notes on the Sony Programmable I/O controller
2083#  This is a temporary driver that should someday be replaced by something
2084#  that hooks into the ACPI layer. The device is hooked to the PIIX4's
2085#  General Device 10 decoder, which means you have to fiddle with PCI
2086#  registers to map it in, even though it is otherwise treated here as
2087#  an ISA device. At the moment, the driver polls, although the device
2088#  is capable of generating interrupts. It largely undocumented.
2089#  The port location in the hint is where you WANT the device to be
2090#  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2091#  is the only thing truly supported, but aparently a fair percentage
2092#  of the Vaio extra features are controlled by this device.
2093
2094# Notes on the Stallion stl and stli drivers:
2095#  See src/i386/isa/README.stl for complete instructions.
2096#  This is version 0.0.5alpha, unsupported by Stallion.
2097#  The stl driver has a secondary IO port hard coded at 0x280.  You need
2098#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2099#  The "flags" and "msize" settings on the stli driver depend on the board:
