# 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 X86_64_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	pc64
machine		x86_64
machine_arch	x86_64

#
# This is the ``identification'' of the kernel.  Usually this should
# be the same as the name of your kernel.
#
ident		X86_64_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.

# 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.

#
# 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 	BLKDEV_IOSIZE=8192

# This allows you to actually store this configuration file into

#
options 	INCLUDE_CONFIG_FILE     # Include this file in kernel

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

#  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

#  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

# feature works properly.
#
# IPFIREWALL3 is based on a newer version of FreeBSD's ipfw2, along with
# some enhancements. See ipfw3(4).
#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to

# 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.

# HARDWARE DEVICE CONFIGURATION

# ISA devices:

#
# Mandatory ISA devices: isa
#
device		isa

#
# 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 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, DragonFly 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).
#
# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to

# Technologies PN102TX, and the AOpen/Acer ALN-320.
#
# The `wb' device provides support for various fast ethernet adapters
# based on the Winbond W89C840F chip. Note: this is not the same as
# the Winbond W89C940F, which is an NE2000 clone.
#
# The `xl' device provides support for the 3Com 3c900, 3c905 and
# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
# Dell Precision desktop machines and the integrated 3c905-TX chips
# in Dell Latitude laptop docking stations.
#
# The 'bktr' device is a PCI video capture device using the Brooktree
# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
# TV card, eg Miro PC/TV, Hauppauge WinCast/TV WinTV, VideoLogic Captivator,

# 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

# 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 src/sys/dev/raid/dpt for debugging and other subtle options.
#   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_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/raid/dpt/dpt.h
#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
