# NB: You probably don't want to try running a kernel built from this
# file.  Instead, you should start from GENERIC, and add options from
# this file as required.

# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family based IBM-PC and
# compatibles.

machine		i386

#
# This is the ``identification'' of the kernel.  Usually this should
# be the same as the name of your kernel.
#
ident		LINT

#
# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a complicated formula defined in param.c.
#
maxusers	10

#
# The `makeoptions' parameter allows variables to be passed to the
# generated Makefile in the build area.  DEBUG happens to be magic.
# The following is equivalent to 'config -g KERNELNAME' and creates
# 'kernel.debug' compiled with -g debugging as well as a normal
# 'kernel'.  Use 'make install.debug' to install the debug kernel
# but that isn't normally necessary as the debug symbols are not loaded
# by the kernel and are not useful there anyway.
#
# KERNEL can be overridden so that you can change the default name of your
# kernel.
#
#makeoptions	DEBUG=-g		#Build kernel with gdb(1) debug symbols
#makeoptions	KERNEL=foo		#Build kernel "foo" and install "/foo"

#
# Certain applications can grow to be larger than the 128M limit
# that FreeBSD initially imposes.  Below are some options to
# allow that limit to grow to 256MB, and can be increased further
# with changing the parameters.  MAXDSIZ is the maximum that the
# limit can be set to, and the DFLDSIZ is the default value for
# the limit.  You might want to set the default lower than the
# max, and explicitly set the maximum with a shell command for processes
# that regularly exceed the limit like INND.
#
options 	MAXDSIZ="(256*1024*1024)"
options 	DFLDSIZ="(256*1024*1024)"

#
# BLKDEV_IOSIZE sets the default block size used in user block
# device I/O.  Note that this value will be overriden by the label
# when specifying a block device from a label with a non-0
# partition blocksize.  The default is PAGE_SIZE.
#
options		BLKDEV_IOSIZE=8192

# Options for the VM subsystem

options 	PQ_LARGECACHE		# color for 512k/16k cache
#options 	PQ_HUGECACHE		# color for 1024k/16k cache

# This allows you to actually store this configuration file into
# the kernel binary itself, where it may be later read by saying:
#    strings -aout -n 3 /kernel | grep ^___ | sed -e 's/^___//' > MYKERNEL

# CPU OPTIONS

#
# You must specify at least one CPU (the one you intend to run on);
# deleting the specification for CPUs you don't need to use may make
# parts of the system run faster.  This is especially true removing
# I386_CPU.
#
cpu		I386_CPU
cpu		I486_CPU
cpu		I586_CPU		# aka Pentium(tm)
cpu		I686_CPU		# aka Pentium Pro(tm)

#
# Options for CPU features.
#
# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
# BlueLightning CPU.  It works only with Cyrix FPU, and this option
# should not be used with Intel FPU.
#
# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
# CPU if CPU supports it. The default is double-clock mode on
# BlueLightning CPU box.
#
# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
#
# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
# mapped mode.  Default is 2-way set associative mode.
#
# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
#
# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
# reorder).  This option should not be used if you use memory mapped
# I/O device(s).
#
# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
#
# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
# for i386 machines.
#
# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
# (no clock delay).
#
# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
# 1).
#
# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
#
# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
# enters suspend mode following execution of HALT instruction.
#
# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
# K5/K6/K6-2 cpus.
#
# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
# flush at hold state.
#
# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
# without cache flush at hold state, and (2) write-back CPU cache on
# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
#
# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
# executed.  This should be included for ALL kernels that won't run
# on a Pentium.
#
# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
# which indicates that the 15-16MB range is *definitely* not being
# occupied by an ISA memory hole.
#
# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
# These options may crash your system.
#
# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
# in write-through mode when revision < 2.7.  If revision of Cyrix
# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
#
# NOTE 3: This option may cause failures for software that requires
# locked cycles in order to operate correctly.

# COMPATIBILITY OPTIONS

#
# Implement system calls compatible with 4.3BSD and older versions of
# FreeBSD.  You probably do NOT want to remove this as much current code
# still relies on the 4.3 emulation.
#
options 	COMPAT_43

#
# Allow user-mode programs to manipulate their local descriptor tables.
# This option is required for the WINE Windows(tm) emulator, and is
# not used by anything else (that we know of).
#
options 	USER_LDT		#allow user-level control of i386 ldt

#
# These three options provide support for System V Interface
# Definition-style interprocess communication, in the form of shared
# memory, semaphores, and message queues, respectively.
#
options 	SYSVSHM
options 	SYSVSEM
options 	SYSVMSG

#
# This option includes a MD5 routine in the kernel, this is used for

#####################################################################
# DEBUGGING OPTIONS

#
# Enable the kernel debugger.
#
options 	DDB

#
# Don't drop into DDB for a panic. Intended for unattended operation
# where you may want to drop to DDB from the console, but still want
# the machine to recover from a panic
#
options 	DDB_UNATTENDED

#
# If using GDB remote mode to debug the kernel, there's a non-standard
# extension to the remote protocol that can be used to use the serial
# port as both the debugging port and the system console.  It's non-
# standard and you're on your own if you enable it.  See also the
# "remotechat" variables in the FreeBSD specific version of gdb.
#
options 	GDB_REMOTE_CHAT

#
# KTRACE enables the system-call tracing facility ktrace(2).
#
options 	KTRACE			#kernel tracing

#
# The INVARIANTS option is used in a number of source files to enable
# extra sanity checking of internal structures.  This support is not
# enabled by default because of the extra time it would take to check
# for these conditions, which can only occur as a result of
# programming errors.
#
options 	INVARIANTS

#
# The INVARIANT_SUPPORT option makes us compile in support for
# verifying some of the internal structures.  It is a prerequisite for
# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be
# called.  The intent is that you can set 'INVARIANTS' for single
# source files (by changing the source file or specifying it on the
# command line) if you have 'INVARIANT_SUPPORT' enabled.
#
options 	INVARIANT_SUPPORT

#
# The DIAGNOSTIC option is used to enable extra debugging information
# from some parts of the kernel.  As this makes everything more noisy,
# it is disabled by default.
#
options 	DIAGNOSTIC

#
# PERFMON causes the driver for Pentium/Pentium Pro performance counters
# to be compiled.  See perfmon(4) for more information.
#
options 	PERFMON


#
# This option let some drivers co-exist that can't co-exist in a running
# system.  This is used to be able to compile all kernel code in one go for
# quality assurance purposes (like this file, which the option takes it name
# from.)
#
options COMPILING_LINT


# XXX - this doesn't belong here.
# Allow ordinary users to take the console - this is useful for X.

#  The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
#  The `ppp' pseudo-device implements the Point-to-Point Protocol.
#  The `bpf' pseudo-device enables the Berkeley Packet Filter.  Be

# limits the number of times a matching entry can be logged.
#
# WARNING:  IPFIREWALL defaults to a policy of "deny ip from any to any"

#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to

# if you are using it as an as-needed filter for specific problems as
# they arise, then this may be for you.  Changing the default to 'allow'

# SCSI DEVICES

# SCSI DEVICE CONFIGURATION

# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers.  The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit.  In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus.  This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.

# This old behavior is maintained as the default behavior.  The unit
# assignment begins with the first non-wired down unit for a device
# type.  For example, if you wire a disk as "da3" then the first
# non-wired disk will be assigned da4.

# The syntax for wiring down devices is:

# controller	scbus0 at ahc0		# Single bus device
# controller	scbus1 at ahc1 bus 0	# Single bus device
# controller	scbus3 at ahc2 bus 0	# Twin bus device
# controller	scbus2 at ahc2 bus 1	# Twin bus device
# disk 		da0 at scbus0 target 0 unit 0
# disk		da1 at scbus3 target 1
# disk		da2 at scbus2 target 3
# tape		sa1 at scbus1 target 6
# device	cd0 at scbus?

# "units" (SCSI logical unit number) that are not specified are

# HARDWARE DEVICE CONFIGURATION

# ISA and EISA devices:
# EISA support is available for some device, so they can be auto-probed.
# Micro Channel is not supported at all.

#
# Mandatory ISA devices: isa, npx
#
controller	isa0

#
# Options for `isa':
#
# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
# This option breaks suspend/resume on some portables.
#
# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller.  This saves about 0.7-1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated
# versions.
#
# MAXMEM specifies the amount of RAM on the machine; if this is not
# specified, FreeBSD will first read the amount of memory from the CMOS
# RAM, so the amount of memory will initially be limited to 64MB or 16MB
# depending on the BIOS.  If the BIOS reports 64MB, a memory probe will
# then attempt to detect the installed amount of RAM.  If this probe
# fails to detect >64MB RAM you will have to use the MAXMEM option.
# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
# be 131072 (128 * 1024).
#
# TUNE_1542 enables the automatic ISA bus speed selection for the
# Adaptec 1542 boards. Does not work for all boards, use it with caution.
#
# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
# reset the CPU for reboot.  This is needed on some systems with broken
# keyboard controllers.

# The Numeric Processing eXtension driver.  In addition to this, you

# will be used, unless it is found to be broken or unless "flags" to
# npx0 includes "0x08", which requests preference for the emulator.
device		npx0	at nexus? port IO_NPX flags 0x0 irq 13

#	0x04	don't use the npx registers to optimize copyin or copyout.
#	0x08	use emulator even if hardware FPU is available.
# The npx registers are normally used to optimize copying and zeroing when
# all of the following conditions are satisfied:
#	I586_CPU is an option
#	the cpu is an i586 (perhaps not a Pentium)
#	the probe for npx0 succeeds
#	INT 16 exception handling works.
# Then copying and zeroing using the npx registers is normally 30-100% faster.
# The flags can be used to control cases where it doesn't work or is slower.
# Setting them at boot time using userconfig works right (the optimizations
# are not used until later in the bootstrap when npx0 is attached).

#
# ST-506, ESDI, and IDE hard disks: `wdc' and `wd'
#
# The flags fields are used to enable the multi-sector I/O and
# the 32BIT I/O modes.  The flags may be used in either the controller
# definition or in the individual disk definitions.  The controller
# definition is supported for the boot configuration stuff.
#
# Each drive has a 16 bit flags value defined:
#	The low 8 bits are the maximum value for the multi-sector I/O,
#	where 0xff defaults to the maximum that the drive can handle.
#	The high bit of the 16 bit flags (0x8000) allows probing for
#	32 bit transfers.  Bit 14 (0x4000) enables a hack to wake
#	up powered-down laptop drives.  Bit 13 (0x2000) allows
#	probing for PCI IDE DMA controllers, such as Intel's PIIX
#	south bridges. Bit 12 (0x1000) sets LBA mode instead of the
#	default CHS mode for accessing the drive. See the wd.4 man page.
#
# The flags field for the drives can be specified in the controller
# specification with the low 16 bits for drive 0, and the high 16 bits
# for drive 1.
# e.g.:
#controller	wdc0	at isa? port IO_WD1 irq 14 flags 0x00ff8004
#
# specifies that drive 0 will be allowed to probe for 32 bit transfers and
# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
# allowed to probe for 32 bit transfers, but will allow multi-sector
# transfers up to the maximum that the drive supports.
#
# If you are using a PCI controller that is not running in compatibility
# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
# such as:
#
#controller	wdc2	at isa? port 0 irq ? flags 0xa0ffa0ff
#disk		wd4	at wdc2 drive 0
#disk		wd5	at wdc2 drive 1
#
#controller	wdc3	at isa? port 0 irq ? flags 0xa0ffa0ff
#disk		wd6	at wdc3 drive 0
#disk		wd7	at wdc3 drive 1
#
# Note that the above config would be useful for a Promise card, when used
# on a MB that already has a PIIX controller.  Note the bogus irq and port
# entries.  These are automatically filled in by the IDE/PCI support.

#  The flags takes the following meaning for apm0:
#    0x0020  Statclock is broken.
#    0x0011  Limit APM protocol to 1.1 or 1.0
#    0x0010  Limit APM protocol to 1.0
#  If apm is omitted, some systems require sysctl -w kern.timcounter.method=1
#  for correct timekeeping.

# Notes on the spigot:
#  The video spigot is at 0xad6.  This port address can not be changed.
#  The irq values may only be 10, 11, or 15
#  I/O memory is an 8kb region.  Possible values are:
#    0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
#    The start address must be on an even boundary.
#  Add the following option if you want to allow non-root users to be able
#  to access the spigot.  This option is not secure because it allows users
#  direct access to the I/O page.
#  	options SPIGOT_UNSECURE

# Notes on the Comtrol Rocketport driver:
#
# The exact values used for rp0 depend on how many boards you have
# in the system.  The manufacturer's sample configs are listed as:
#
#   Comtrol Rocketport ISA single card
#               device  rp0     at isa? port 0x280
#
#   If instead you have two ISA cards, one installed at 0x100 and the
#   second installed at 0x180, then you should add the following to
#   your kernel configuration file:
#
#               device  rp0     at isa? port 0x100
#               device  rp1     at isa? port 0x180
#
#   For 4 ISA cards, it might be something like this:
#
#               device  rp0     at isa? port 0x180
#               device  rp1     at isa? port 0x100
#               device  rp2     at isa? port 0x340
#               device  rp3     at isa? port 0x240
#
#   And for PCI cards, you only need say:
#
#               device rp0
#               device rp1
#               ...
#   Note: Make sure that any Rocketport PCI devices are specified BEFORE the
#   ISA Rocketport devices.

# Notes on the Digiboard driver:
#
# The following flag values have special meanings:
#	0x01 - alternate layout of pins (dgb & dgm)
#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)

# Notes on the Specialix SI/XIO driver:
#  **This is NOT a Specialix supported Driver!**
#  The host card is memory, not IO mapped.
#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
#  The cards can use an IRQ of 11, 12 or 15.

# Notes on the Stallion stl and stli drivers:
#  See src/i386/isa/README.stl for complete instructions.
#  This is version 0.0.5alpha, unsupported by Stallion.
#  The stl driver has a secondary IO port hard coded at 0x280.  You need
#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
#  The "flags" and "iosiz" settings on the stli driver depend on the board:
#	EasyConnection 8/64 ISA:     flags 23         iosiz 0x1000
#	EasyConnection 8/64 EISA:    flags 24         iosiz 0x10000
#	EasyConnection 8/64 MCA:     flags 25         iosiz 0x1000

# Enable extra debugging code for locks.  This stores the filename and
# line of whatever acquired the lock in the lock itself, and change a
# number of function calls to pass around the relevant data.  This is
# not at all useful unless you are debugging lock code.  Also note

# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
# The DPT controllers are commonly re-licensed under other brand-names -
# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
# Compaq are actually DPT controllers.
#
# See sys/dev/dpt for debugging and other subtle options.
#   DPT_VERIFY_HINTR        Performs some strict hardware interrupts testing.
#                           Only use if you suspect PCI bus corruption problems
#   DPT_RESTRICTED_FREELIST Normally, the freelist used by the DPT for queue
#                           will grow to accommodate increased use. This growth
#                           will NOT shrink.  To restrict the number of queue
#                           slots to exactly what the DPT can hold at one time,
#                           enable this option.
#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
#                           instruments are enabled.  The tools in
#                           /usr/sbin/dpt_* assume these to be enabled.
#   DPT_FREELIST_IS_STACK   For optimal L{1,2} CPU cache utilization, enable
#                           this option.  Otherwise, the transaction queue is
#                           a LIFO.  I cannot measure the performance gain.
#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
#                           If you ant the driver to handle timeouts, enable
#                           this option.  If your system is very busy, this
#                           option will create more trouble than solve.
#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
#                           wait when timing out with the above option.
#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
#                           any interrupt that got lost.  Seems to help in some
#                           DPT-firmware/Motherboard combinations.  Minimal
#                           cost, great benefit.
#  DPT_RESET_HBA            Make "reset" actually reset the controller
#                           instead of fudging it.  Only enable this if you
#			    are 100% certain you need it.
#  DPT_SHUTDOWN_SLEEP       Reset controller if a request take more than
#                           this number of seconds.  Do NOT enable this
#			    unless you are really, really, really certain
#			    you need it.  You are advised to call Simon (the
#			    driver author) before setting it, and NEVER,
#			    EVER set it to less than 300s (5 minutes).
