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.

63# Certain applications can grow to be larger than the 128M limit
64# that FreeBSD initially imposes.  Below are some options to
65# allow that limit to grow to 256MB, 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.

76# BLKDEV_IOSIZE sets the default block size used in user block
77# device I/O.  Note that this value will be overriden by the label
78# when specifying a block device from a label with a non-0
79# partition blocksize.  The default is PAGE_SIZE.

153# CPU OPTIONS
154
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.  This is especially true removing
159# I386_CPU.

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.

333# KTR is a kernel tracing mechanism imported from BSD/OS.  Currently it
334# has no userland interface aside from a few sysctl's.  It is enabled with
335# the KTR option.  The KTR_EXTEND option causes trace events to be generated
336# as a string from snprintf rather than as a string and up to 5 argument
337# pointers.  KTR_ENTRIES defines the number of entries in the circular trace
338# buffer.  KTR_COMPILE defines the mask of events to compile into the kernel
339# as defined by the KTR_* constants in <sys/ktr.h>.  KTR_MASK defines the
340# initial value of the ktr_mask variable which determines at runtime what
341# events to trace.  KTR_CPUMASK determines which CPU's log events, with
342# bit X corresponding to cpu X.

805# SCSI DEVICES
806
807# SCSI DEVICE CONFIGURATION
808
809# The SCSI subsystem consists of the `base' SCSI code, a number of
810# high-level SCSI device `type' drivers, and the low-level host-adapter
811# device drivers.  The host adapters are listed in the ISA and PCI
812# device configuration sections below.
813#
814# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
815# that a given bus, target, and LUN always come on line as the same
816# device unit.  In earlier versions the unit numbers were assigned
817# in the order that the devices were probed on the SCSI bus.  This
818# means that if you removed a disk drive, you may have had to rewrite
819# your /etc/fstab file, and also that you had to be careful when adding
820# a new disk as it may have been probed earlier and moved your device
821# configuration around.
822
823# This old behavior is maintained as the default behavior.  The unit
824# assignment begins with the first non-wired down unit for a device
825# type.  For example, if you wire a disk as "da3" then the first
826# non-wired disk will be assigned da4.
827
828# The syntax for wiring down devices is:
829
830hint.scbus.0.at="ahc0"

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

1902#  The flags takes the following meaning for apm0:
1903#    0x0020  Statclock is broken.
1904#  If apm is omitted, some systems require sysctl -w kern.timecounter.method=1

1907# Notes on the spigot:
1908#  The video spigot is at 0xad6.  This port address can not be changed.

1917
1918# Notes on the Comtrol Rocketport driver:
1919#
1920# The exact values used for rp0 depend on how many boards you have
1921# in the system.  The manufacturer's sample configs are listed as:
1922#
1923#               device  rp	# core driver support
1924#
1925#   Comtrol Rocketport ISA single card
1926#		hints.rp.0.at="isa"
1927#		hints.rp.0.port="0x280"
1928#
1929#   If instead you have two ISA cards, one installed at 0x100 and the
1930#   second installed at 0x180, then you should add the following to
1931#   your kernel probe hints:
1932#		hints.rp.0.at="isa"
1933#		hints.rp.0.port="0x100"
1934#		hints.rp.1.at="isa"
1935#		hints.rp.1.port="0x180"
1936#
1937#   For 4 ISA cards, it might be something like this:
1938#		hints.rp.0.at="isa"
1939#		hints.rp.0.port="0x180"
1940#		hints.rp.1.at="isa"
1941#		hints.rp.1.port="0x100"
1942#		hints.rp.2.at="isa"
1943#		hints.rp.2.port="0x340"
1944#		hints.rp.3.at="isa"
1945#		hints.rp.3.port="0x240"
1946#
1947#   And for PCI cards, you need no hints.
1948
1949# Notes on the Digiboard driver:
1950#
1951# The following flag values have special meanings:
1952#	0x01 - alternate layout of pins (dgb & dgm)
1953#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1954
1955# Notes on the Specialix SI/XIO driver:
1956#  The host card is memory, not IO mapped.
1957#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1958#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1959#  The cards can use an IRQ of 11, 12 or 15.
1960
1961# Notes on the Stallion stl and stli drivers:
1962#  See src/i386/isa/README.stl for complete instructions.
1963#  This is version 0.0.5alpha, unsupported by Stallion.
1964#  The stl driver has a secondary IO port hard coded at 0x280.  You need
1965#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1966#  The "flags" and "msize" settings on the stli driver depend on the board:
1967#	EasyConnection 8/64 ISA:     flags 23         msize 0x1000
1968#	EasyConnection 8/64 EISA:    flags 24         msize 0x10000
