# 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
#
# 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.
#

# 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.

#
# 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 is a new scheduler that has been designed for SMP and has some
# advantages for UP as well. It is intended to replace the 4BSD scheduler
# over time. NOTE: SCHED_ULE is currently considered experimental and is
# not recommended for production use at this time.

# SMP OPTIONS:
#
# SMP enables building of a Symmetric MultiProcessor Kernel.
# Mandatory:
options SMP # Symmetric MultiProcessor Kernel
# ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin
# if the thread that currently owns the mutex is executing on another
# CPU. This behaviour is enabled by default, so this option can be used
# to disable it.
options NO_ADAPTIVE_MUTEXES
# ADAPTIVE_GIANT causes the Giant lock to also be made adaptive when
# running without NO_ADAPTIVE_MUTEXES. Normally, because Giant is assumed
# to be held for extended periods, contention on Giant will cause a thread
# to sleep rather than spinning.
options ADAPTIVE_GIANT
# MUTEX_NOINLINE forces mutex operations to call functions to perform each
# operation rather than inlining the simple cases. This can be used to
# shrink the size of the kernel text segment. Note that this behavior is
# already implied by the INVARIANT_SUPPORT, INVARIANTS, KTR, LOCK_PROFILING,
# and WITNESS options.
options MUTEX_NOINLINE
# MUTEX_WAKE_ALL changes the mutex unlock algorithm to wake all waiters
# when a contested mutex is released rather than just awaking the highest
# priority waiter.
options MUTEX_WAKE_ALL
# RWLOCK_NOINLINE forces rwlock operations to call functions to perform each
# operation rather than inlining the simple cases. This can be used to
# shrink the size of the kernel text segment. Note that this behavior is
# already implied by the INVARIANT_SUPPORT, INVARIANTS, KTR, LOCK_PROFILING,
# and WITNESS options.
options RWLOCK_NOINLINE
# SMP Debugging Options:
#
# PREEMPTION allows the threads that are in the kernel to be preempted
# by higher priority 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.
# TURNSTILE_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.

# 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. Note that some architectures that
# are supported by FreeBSD do not include support for certain important

# Enable FreeBSD4 compatibility syscalls
options COMPAT_FREEBSD4
# Enable FreeBSD5 compatibility syscalls
options COMPAT_FREEBSD5
# Enable FreeBSD6 compatibility syscalls

# DEBUGGING OPTIONS
#
# Compile with kernel debugger related code.
#
options KDB
#
# Print a stack trace of the current thread on the console for a panic.
#
options KDB_TRACE
#
# Don't enter the debugger for a panic. Intended for unattended operation
# where you may want to enter the debugger from the console, but still want

options DDB
#
# Print the numerical value of symbols in addition to the symbolic
# representation.
#

#
# Enable the remote gdb debugger backend.
#
options GDB
#
# SYSCTL_DEBUG enables a 'sysctl' debug tree that can be used to dump the
# contents of the registered sysctl nodes on the console. It is disabled by
# default because it generates excessively verbose console output that can
# interfere with serial console operation.
#
options SYSCTL_DEBUG
#
# DEBUG_MEMGUARD builds and enables memguard(9), a replacement allocator
# for the kernel used to detect modify-after-free scenarios. See the
# memguard(9) man page for more information on usage.
#
options DEBUG_MEMGUARD
#
# DEBUG_REDZONE enables buffer underflows and buffer overflows detection for
# malloc(9).
#
options DEBUG_REDZONE
#
# KTRACE enables the system-call tracing facility ktrace(2). To be more
# SMP-friendly, KTRACE uses a worker thread to process most trace events
# asynchronously to the thread generating the event. This requires a
# pre-allocated store of objects representing trace events. The
# KTRACE_REQUEST_POOL option specifies the initial size of this store.
# The size of the pool can be adjusted both at boottime and runtime via
# the kern.ktrace_request_pool tunable and sysctl.
#
options KTRACE #kernel tracing
options KTRACE_REQUEST_POOL=101
#
# KTR is a kernel tracing mechanism imported from BSD/OS. Currently
# it has no userland interface aside from a few sysctl's. It is
# enabled with the KTR option. KTR_ENTRIES defines the number of
# entries in the circular trace buffer; it must be a power of two.
# KTR_COMPILE defines the mask of events to compile into the kernel as
# defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the
# initial value of the ktr_mask variable which determines at runtime
# what events to trace. KTR_CPUMASK determines which CPU's log
# events, with bit X corresponding to CPU X. 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.

# files based on a kernel event stream. Records are written asynchronously
# in a worker thread.
#
options ALQ
options KTR_ALQ
#
# 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. Also, if you
# wish to build a kernel module with 'INVARIANTS', then adding
# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary
# infrastructure without the added overhead.
#
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
#
# REGRESSION causes optional kernel interfaces necessary only for regression
# testing to be enabled. These interfaces may constitute security risks
# when enabled, as they permit processes to easily modify aspects of the
# run-time environment to reproduce unlikely or unusual (possibly normally
# impossible) scenarios.
#
options REGRESSION
#
# RESTARTABLE_PANICS allows one to continue from a panic as if it were
# a call to the debugger to continue from a panic as instead. It is only
# useful if a kernel debugger is present. To restart from a panic, reset
# the panicstr variable to NULL and continue execution. This option is
# for development use only and should NOT be used in production systems
# to "workaround" a panic.
#
#options RESTARTABLE_PANICS
#
# 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

# soon to have a new base RFC and many many more
# extensions. This release supports all the extensions
# including many drafts (most about to become RFC's).
# It is the premeier SCTP implementation in the NET
# and is quite well tested.
#
# Note YOU MUST have both INET and INET6 defined.
# you don't have to enable V6, but SCTP is
# dual stacked and so far we have not teased apart
# the V6 and V4.. since an association can span
# both a V6 and V4 address at the SAME time :-)
#
options SCTP
# There are bunches of options:
# this one turns on all sorts of
# nastly printing that you can
# do. Its all controled by a
# bit mask (settable by socket opt and
# by sysctl). Including will not cause
# logging until you set the bits.. but it
# can be quite verbose.. so without this
# option we don't do any of the tests for
# bits and prints.. which makes the code run
# faster.. if you are not debugging don't use.

# High speed enables sally floyds HS TCP optioin
# for congestion control increase, use only in
# very HS networks and with caution since I doubt

# internet its best NOT to enable.
#
options SCTP_HIGH_SPEED
#
# This option turns off the CRC32c checksum. Basically
# You will not be able to talk to anyone else that
# has not done this. Its more for expermentation to
# see how much CPU the CRC32c really takes. Most new
# cards for TCP support checksum offload.. so this
# option gives you a "view" into what SCTP would be
# like with such an offload (which only exists in
# high in iSCSI boards so far). With the new
# splitting 8's algorithm its not as bad as it used
# to be.. but it does speed things up try only
# for in a captured lab environment :-)
options SCTP_WITH_NO_CSUM
#
# Logging, this is another debug tool thats way

# IPFIREWALL enables support for IP firewall construction, in
# conjunction with the `ipfw' program. IPFIREWALL_VERBOSE sends
# logged packets to the system logger. IPFIREWALL_VERBOSE_LIMIT
# limits the number of times a matching entry can be logged.
#
# WARNING: IPFIREWALL defaults to a policy of "deny ip from any to any"
# and if you do not add other rules during startup to allow access,
# YOU WILL LOCK YOURSELF OUT. It is suggested that you set firewall_type=open
# in /etc/rc.conf when first enabling this feature, then refining the
# firewall rules in /etc/rc.firewall after you've tested that the new kernel
# feature works properly.
#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to
# allow everything. Use with care, if a cracker can crash your
# firewall machine, they can get to your protected machines. However,
# 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'
# means that you won't get stuck if the kernel and /sbin/ipfw binary get
# out of sync.
#
# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''. It
# depends on IPFIREWALL if compiled into the kernel.
#
# IPFIREWALL_FORWARD enables changing of the packet destination either
# to do some sort of policy routing or transparent proxying. Used by
# ``ipfw forward''. All redirections apply to locally generated
# packets too. Because of this great care is required when
# crafting the ruleset.
#
# IPSTEALTH enables code to support stealth forwarding (i.e., forwarding
# packets without touching the TTL). This can be useful to hide firewalls
# from traceroute and similar tools.

# 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.
#
#
# 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.

# configuration as the "pass" driver.

# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).

# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various

# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
# If you ant the driver to handle timeouts, enable

# 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.
