# LINT -- config file for checking all the sources, tries to pull in
#       as much of the source tree as it can.

# See the kernconf(5) manual page for more information on the format of
# this file.
#
# 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.
#

# These directives are mandatory.  The machine directive specifies the
# platform and the machine_arch directive specifies the cpu architecture.
#
platform        pc32
machine         i386
machine_arch    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 formula defined in subr_param.c.  Setting
# maxusers to 0 will cause the system to auto-size based on physical
# memory.
#
maxusers        10

#
# The `makeoptions' parameter allows variables to be passed to the
# generated Makefile in the build area.
#
# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
# after most other flags.  Here we use it to inhibit use of non-optimal
# gcc builtin functions (e.g., memcmp).
#
# 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.
#
# MODULES_OVERRIDE can be used to limit modules built to a specific list.
#
# INSTALLSTRIPPED can be set to cause installkernel to install stripped
# kernels and modules rather than a kernel and modules with debug symbols.
#
# INSTALLSTRIPPEDMODULES can be set to allow a full debug kernel to be
# installed, but to strip the installed modules.
#
makeoptions     CONF_CFLAGS=-fno-builtin  #Don't allow use of memcmp, etc.
#makeoptions    DEBUG=-g                #Build kernel with gdb(1) debug symbols

# Certain applications can grow to be larger than the 128M limit
# that DragonFly 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.  MAXSSIZ is the maximum that the stack limit can be
# set to.  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         DFLDSIZ="(256*1024*1024)"

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

# Options for the VM subsystem.
options         PQ_CACHESIZE=512        # color for 512k/16k cache

#
options         INCLUDE_CONFIG_FILE     # Include this file in kernel

#
# The root device and filesystem type can be compiled in;

# SMP enables building of a Symmetric MultiProcessor Kernel.
# APIC_IO enables the use of the IO APIC for Symmetric I/O.

#
#  An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard.
#
#  Be sure to disable 'cpu I486_CPU' for SMP kernels.
#
#  Check the 'Rogue SMP hardware' section to see if additional options
#   are required by your hardware.
#

# To make an SMP kernel both SMP and APIC_IO are usually

# 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.
#
cpu             I486_CPU
cpu             I586_CPU                # aka Pentium(tm)
cpu             I686_CPU                # aka Pentium Pro(tm)

#
# Options for CPU features.
#
# CPU_AMD64X2_INTR_SPAM tries to route HyperTransport EXTINT and NMI
# messages to LINT0 on the local APIC when the BIOS has forgotten to
# do that.  If this is not done on a multi-core cpu, EXTINT and NMI
# get routed to the INTR/NMI pins on *BOTH* cores simultaneously, causing
# two INTA ack cycles one of which will almost certainly result in a
# spurious interrupt vector being presented.  This is often visible as 
# an unmaskable IRQ 7 which occurs for every normal interrupt that occurs
# on a system.
#
# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
# forgotten to enable them.
#
# 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_DISABLE_SSE disables SSE/MMX2 instructions support.
#
# CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some
# Pentium(tm) 4 and (possibly) later CPUs.  When enabled and detected,
# TCC supports restricting power consumption using the hw.p4tcc.*
# sysctls.  This operates independently of SpeedStep and is useful on
# systems where other mechanisms such as apm(4) or acpi(4) don't work.
#
# CPU_ENABLE_EST enables support for Enhanced SpeedStep technology
# found in Pentium(tm) M processors.
#
# 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_L2_LATENCY specified the L2 cache latency value.  This option is used
# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
# The default value is 5.
#
# CPU_ELAN enables support for AMDs ElanSC520 CPU.
#
# CPU_GEODE enables support for AMD Geode LX, Geode SC1100 and AMD CS5536
#
# 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_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
#
# 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 option is only needed if I586_CPU is also defined,
# and should be included for any non-Pentium CPU that defines it.
#
# 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.

#  The `loop' pseudo-device is MANDATORY when networking is enabled.
#  The `ether' pseudo-device provides generic code to handle
#  Ethernets; it is MANDATORY when a Ethernet device driver is

#  The `sppp' pseudo-device serves a similar role for certain types
#  of synchronous PPP links (like `ar').
#  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
#  aware of the legal and administrative consequences of enabling this
#  option.  The number of devices determines the maximum number of
#  simultaneous BPF clients programs runnable.
#  The `disc' pseudo-device implements a minimal network interface,
#  which throws away all packets sent and never receives any.  It is
#  included for testing purposes.  This shows up as the 'ds' interface.
#  The `tun' pseudo-device implements (user-)ppp and nos-tun
#  The `gif' pseudo-device implements IPv6 over IP4 tunneling,
#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
#  IPv6 over IPv6 tunneling.
#  The `gre' device implements two types of IP4 over IP4 tunneling:
#  GRE and MOBILE, as specified in the RFC1701 and RFC2004.
#  The `faith' pseudo-device captures packets sent to it and diverts them
#  to the IPv4/IPv6 translation daemon.
#  The `stf' device implements 6to4 encapsulation.
#  The `ef' pseudo-device provides support for multiple ethernet frame types
#  specified via ETHER_* options. See ef(4) for details.
#
# The PPP_BSDCOMP option enables support for compress(1) style entire

# 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:

# device        scbus0 at ahc0          # Single bus device
# device        scbus1 at ahc1 bus 0    # Single bus device
# device        scbus3 at ahc2 bus 0    # Twin bus device
# device        scbus2 at ahc2 bus 1    # Twin bus device
# device        da0 at scbus0 target 0 unit 0
# device        da1 at scbus3 target 1
# device        da2 at scbus2 target 3
# device        sa1 at scbus1 target 6
# device        cd

# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.

# All SCSI devices allocate as many units as are required.

# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
# configuration and doesn't have to be explicitly configured.

# Notes on APM
#  The flags takes the following meaning for apm0:
#    0x0020  Statclock is broken.
#  If apm is omitted, some systems require sysctl -w kern.timecounter.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 rp

# 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/sys/platform/pc32/isa/README.stl for complete instructions.
#  This is version 2.0.0, unsupported by Stallion.
#  The stl driver has a secondary IO port hard coded at 0x280.  You need
#     to change src/sys/dev/serial/stl/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
#       ONboard ISA:                 flags 4          iosiz 0x10000
#       ONboard EISA:                flags 7          iosiz 0x10000
#       Brumby:                      flags 2          iosiz 0x4000
#       Stallion:                    flags 1          iosiz 0x10000
#  For the PCI cards, "device stl" will suffice.

# Prevents the MSP34xx reset. Good if you initialise the MSP in another OS first
#
# options       BKTR_430_FX_MODE
# Switch Bt878/879 cards into Intel 430FX chipset compatibility mode.
#
# options       BKTR_SIS_VIA_MODE
# Switch Bt878/879 cards into SIS/VIA chipset compatibility mode which is
# needed for some old SiS and VIA chipset motherboards.
# This also allows Bt878/879 chips to work on old OPTi (<1997) chipset
# motherboards and motherboards with bad or incomplete PCI 2.1 support.
# As a rough guess, old = before 1998
#
# options       BKTR_NEW_MSP34XX_DRIVER
# Use new, more complete initialization scheme for the msp34* soundchip.
# Should fix stereo autodetection if the old driver does only output
# mono sound.

#                           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/raid/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.
