# $FreeBSD$
#
# NOTES -- Lines that can be cut/pasted into kernel and hints configs.
#
# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
# 'makeoptions', 'hints', etc. go into the kernel configuration that you
# run config(8) with.
#
# Lines that begin with 'hint.' are NOT for config(8), they go into your
# hints file.  See /boot/device.hints and/or the 'hints' config(8) directive.
#
# Please use ``make LINT'' to create an old-style LINT file if you want to
# do kernel test-builds.
#
# This file contains machine independent kernel configuration notes.  For
# machine dependent notes, look in /sys/<arch>/conf/NOTES.
#

#
# NOTES conventions and style guide:
#
# Large block comments should begin and end with a line containing only a
# comment character.
#
# To describe a particular object, a block comment (if it exists) should
# come first.  Next should come device, options, and hints lines in that
# order.  All device and option lines must be described by a comment that
# doesn't just expand the device or option name.  Use only a concise
# comment on the same line if possible.  Very detailed descriptions of
# devices and subsystems belong in man pages.
#
# A space followed by a tab separates 'options' from an option name.  Two
# spaces followed by a tab separate 'device' from a device name.  Comments
# after an option or device should use one space after the comment character.
# To comment out a negative option that disables code and thus should not be
# enabled for LINT builds, precede 'options' with "#!".
#

#
# 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.
# Omitting this parameter or setting it to 0 will cause the system to
# auto-size based on physical memory.
#
maxusers	10

# To statically compile in device wiring instead of /boot/device.hints
#hints		"LINT.hints"		# Default places to look for devices.

# Use the following to compile in values accessible to the kernel
# through getenv() (or kenv(1) in userland). The format of the file
# is 'variable=value', see kenv(1)
#
#env		"LINT.env"

#
# 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 built-in 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.
#
makeoptions	CONF_CFLAGS=-fno-builtin  #Don't allow use of memcmp, etc.
#makeoptions	DEBUG=-g		#Build kernel with gdb(1) debug symbols
#makeoptions	KERNEL=foo		#Build kernel "foo" and install "/foo"
# Only build ext2fs module plus those parts of the sound system I need.
#makeoptions	MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3"
makeoptions	DESTDIR=/tmp

#
# FreeBSD processes are subject to certain limits to their consumption
# of system resources.  See getrlimit(2) for more details.  Each
# resource limit has two values, a "soft" limit and a "hard" limit.
# The soft limits can be modified during normal system operation, but
# the hard limits are set at boot time.  Their default values are
# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
# 
# 1.  Set the values at kernel build time.  The options below are one
#     way to allow that limit to grow to 1GB.  They can be increased
#     further by changing the parameters:
#	
# 2.  In /boot/loader.conf, set the tunables kern.maxswzone,
#     kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
#     kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
#
# The options in /boot/loader.conf override anything in the kernel
# configuration file.  See the function init_param1 in
# sys/kern/subr_param.c for more details.

#####################################################################
# Scheduler options:
#
# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory.  These options
# select which scheduler is compiled in.
#
# SCHED_4BSD is the historical, proven, BSD scheduler.  It has a global run
# queue and no CPU affinity which makes it suboptimal for SMP.  It has very
# good interactivity and priority selection.
#
# SCHED_ULE provides significant performance advantages over 4BSD on many
# workloads on SMP machines.  It supports cpu-affinity, per-cpu runqueues
# and scheduler locks.  It also has a stronger notion of interactivity 
# which leads to better responsiveness even on uniprocessor machines.  This
# is the default scheduler.
#
# SCHED_STATS is a debugging option which keeps some stats in the sysctl
# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions.

options 	SMP			# Symmetric MultiProcessor Kernel

# MAXCPU defines the maximum number of CPUs that can boot in the system.
# A default value should be already present, for every architecture.
options 	MAXCPU=32

# MAXMEMDOM defines the maximum number of memory domains that can boot in the
# system.  A default value should already be defined by every architecture.
options 	MAXMEMDOM=1

# ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin

# to disable it.
options 	NO_ADAPTIVE_MUTEXES

# ADAPTIVE_RWLOCKS changes the behavior of reader/writer locks to spin
# if the thread that currently owns the rwlock is executing on another

# SMP Debugging Options:
#
# CALLOUT_PROFILING enables rudimentary profiling of the callwheel data
#	  structure used as backend in callout(9).
# PREEMPTION allows the threads that are in the kernel to be preempted by
#	  higher priority [interrupt] threads.  It helps with interactivity
#	  and allows interrupt threads to run sooner rather than waiting.
#	  WARNING! Only tested on amd64 and i386.
# FULL_PREEMPTION instructs the kernel to preempt non-realtime kernel
#	  threads.  Its sole use is to expose race conditions and other
#	  bugs during development.  Enabling this option will reduce
#	  performance and increase the frequency of kernel panics by
#	  design.  If you aren't sure that you need it then you don't.
#	  Relies on the PREEMPTION option.  DON'T TURN THIS ON.
# MUTEX_DEBUG enables various extra assertions in the mutex code.
# SLEEPQUEUE_PROFILING enables rudimentary profiling of the hash table
#	  used to hold active sleep queues as well as sleep wait message
#	  frequency.
# TURNSTILE_PROFILING enables rudimentary profiling of the hash table
#	  used to hold active lock queues.
# UMTX_PROFILING enables rudimentary profiling of the hash table used 
	  to hold active lock queues.
# WITNESS enables the witness code which detects deadlocks and cycles
#         during locking operations.
# WITNESS_KDB causes the witness code to drop into the kernel debugger if
#	  a lock hierarchy violation occurs or if locks are held when going to
#	  sleep.
# WITNESS_SKIPSPIN disables the witness checks on spin mutexes.

# MALLOC_DEBUG_MAXZONES enables multiple uma zones for malloc(9)

# malloc types in that hash class.  This is purely a debugging tool;
# by varying the hash function and tracking which hash class was
# corrupted, the intersection of the hash classes from each instance
# will point to a single malloc type that is being misused.  At this

# KTRACE enables the system-call tracing facility ktrace(2).  To be more

# before malloc(9) is functional.
# KTR_COMPILE defines the mask of events to compile into the kernel as

# what events to trace.  KTR_CPUMASK determines which CPU's log
# events, with bit X corresponding to CPU X.  The layout of the string
# passed as KTR_CPUMASK must match a series of bitmasks each of them
# separated by the "," character (ie:
# KTR_CPUMASK=0xAF,0xFFFFFFFFFFFFFFFF).  KTR_VERBOSE enables
# dumping of KTR events to the console by default.  This functionality
# can be toggled via the debug.ktr_verbose sysctl and defaults to off
# if KTR_VERBOSE is not defined.  See ktr(4) and ktrdump(8) for details.

# CLOCK OPTIONS

# The granularity of operation is controlled by the kernel option HZ whose
# default value (1000 on most architectures) means a granularity of 1ms
# (1s/HZ).  Historically, the default was 100, but finer granularity is
# required for DUMMYNET and other systems on modern hardware.  There are
# reasonable arguments that HZ should, in fact, be 100 still; consider,
# that reducing the granularity too much might cause excessive overhead in
# clock interrupt processing, potentially causing ticks to be missed and thus
# actually reducing the accuracy of operation.

# 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.
#
# It is possible to 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.  (See also option GEOM_VOL for a different solution to this
# problem.)

# 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:

hint.scbus.0.at="ahc0"
hint.scbus.1.at="ahc1"
hint.scbus.1.bus="0"
hint.scbus.3.at="ahc2"
hint.scbus.3.bus="0"
hint.scbus.2.at="ahc2"
hint.scbus.2.bus="1"
hint.da.0.at="scbus0"
hint.da.0.target="0"
hint.da.0.unit="0"
hint.da.1.at="scbus3"
hint.da.1.target="1"
hint.da.2.at="scbus2"
hint.da.2.target="3"
hint.sa.1.at="scbus1"
hint.sa.1.target="6"

# "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 ch driver drives SCSI Media Changer ("jukebox") devices.
#
# The da driver drives SCSI Direct Access ("disk") and Optical Media
# ("WORM") devices.
#
# The sa driver drives SCSI Sequential Access ("tape") devices.
#
# The cd driver drives SCSI Read Only Direct Access ("cd") devices.
#
# The ses driver drives SCSI Environment Services ("ses") and
# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices.
#
# The pt driver drives SCSI Processor devices.
#
# The sg driver provides a passthrough API that is compatible with the
# Linux SG driver.  It will work in conjunction with the COMPAT_LINUX
# option to run linux SG apps.  It can also stand on its own and provide
# source level API compatibility for porting apps to FreeBSD.
#
# Target Mode support is provided here but also requires that a SIM
# (SCSI Host Adapter Driver) provide support as well.
#
# The targ driver provides target mode support as a Processor type device.
# It exists to give the minimal context necessary to respond to Inquiry
# commands. There is a sample user application that shows how the rest
# of the command support might be done in /usr/share/examples/scsi_target.
#
# The targbh driver provides target mode support and exists to respond
# to incoming commands that do not otherwise have a logical unit assigned
# to them.
#
# The pass driver provides a passthrough API to access the CAM subsystem.

# The following 3 hints are used when the UART is a system device (i.e., a
# console or debug port), but only on platforms that don't have any other
# means to pass the information to the kernel.  The unit number of the hint
# is only used to bundle the hints together.  There is no relation to the
# unit number of the probed UART.
hint.uart.0.port="0x3f8"
hint.uart.0.flags="0x10"
hint.uart.0.baud="115200"

# `flags' for serial drivers that support consoles like sio(4) and uart(4):
#	0x10	enable console support for this unit.  Other console flags
#		(if applicable) are ignored unless this is set.  Enabling
#		console support does not make the unit the preferred console.
#		Boot with -h or set boot_serial=YES in the loader.  For sio(4)
#		specifically, the 0x20 flag can also be set (see above).
#		Currently, at most one unit can have console support; the
#		first one (in config file order) with this flag set is
#		preferred.  Setting this flag for sio0 gives the old behavior.
#	0x80	use this port for serial line gdb support in ddb.  Also known
#		as debug port.
#

# Options for serial drivers that support consoles:
options 	BREAK_TO_DEBUGGER	# A BREAK/DBG on the console goes to
					# ddb, if available.

# Solaris implements a new BREAK which is initiated by a character
# sequence CR ~ ^b which is similar to a familiar pattern used on
# Sun servers by the Remote Console.  There are FreeBSD extensions:
# CR ~ ^p requests force panic and CR ~ ^r requests a clean reboot.
options 	ALT_BREAK_TO_DEBUGGER

# MII bus support is required for many PCI Ethernet NICs,
# namely those which use MII-compliant transceivers or implement
# transceiver control interfaces that operate like an MII.  Adding
# "device miibus" to the kernel config pulls in support for the generic
# miibus API, the common support for for bit-bang'ing the MII and all
# of the PHY drivers, including a generic one for PHYs that aren't
# specifically handled by an individual driver.  Support for specific
# PHYs may be built by adding "device mii", "device mii_bitbang" if
# needed by the NIC driver and then adding the appropriate PHY driver.

# SND_DEBUG                    Enable extra debugging code that includes
#                              sanity checking and possible increase of
#                              verbosity.
#
# SND_DIAGNOSTIC               Similar in a spirit of INVARIANTS/DIAGNOSTIC,
#                              zero tolerance against inconsistencies.
#
# SND_FEEDER_MULTIFORMAT       By default, only 16/32 bit feeders are compiled
#                              in. This options enable most feeder converters
#                              except for 8bit. WARNING: May bloat the kernel.
#
# SND_FEEDER_FULL_MULTIFORMAT  Ditto, but includes 8bit feeders as well.
#
# SND_FEEDER_RATE_HP           (feeder_rate) High precision 64bit arithmetic
#                              as much as possible (the default trying to
#                              avoid it). Possible slowdown.
#
# SND_PCM_64                   (Only applicable for i386/32bit arch)
#                              Process 32bit samples through 64bit
#                              integer/arithmetic. Slight increase of dynamic
#                              range at a cost of possible slowdown.
#
# SND_OLDSTEREO                Only 2 channels are allowed, effectively
#                              disabling multichannel processing.

# 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, e.g. Miro PC/TV, Hauppauge WinCast/TV WinTV, VideoLogic Captivator,
# Intel Smart Video III, AverMedia, IMS Turbo, FlyVideo.
#
# options 	OVERRIDE_CARD=xxx
# options 	OVERRIDE_TUNER=xxx
# options 	OVERRIDE_MSP=1
# options 	OVERRIDE_DBX=1
# These options can be used to override the auto detection
# The current values for xxx are found in src/sys/dev/bktr/bktr_card.h
# Using sysctl(8) run-time overrides on a per-card basis can be made
#
# options 	BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
# or
# options 	BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_NTSC
# Specifies the default video capture mode.
# This is required for Dual Crystal (28&35MHz) boards where PAL is used
# to prevent hangs during initialization, e.g. VideoLogic Captivator PCI.
#
# options 	BKTR_USE_PLL
# This is required for PAL or SECAM boards with a 28MHz crystal and no 35MHz
# crystal, e.g. some new Bt878 cards.
#
# options 	BKTR_GPIO_ACCESS
# This enables IOCTLs which give user level access to the GPIO port.
#
# options 	BKTR_NO_MSP_RESET
# Prevents the MSP34xx reset. Good if you initialize 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.

#
# options 	BKTR_USE_FREEBSD_SMBUS
# Compile with FreeBSD SMBus implementation
#
# Brooktree driver has been ported to the new I2C framework. Thus,
# you'll need to have the following 3 lines in the kernel config.
