# 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 manpages.
#
# A space followed by a tab separates 'option' 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 'option' 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. 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.
#
makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc.

#
# Certain applications can grow to be larger than the 512M limit
# that FreeBSD initially imposes. Below are some options to
# allow that limit to grow to 1GB, 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 overriden by the label
# when specifying a block device from a label with a non-0
# partition blocksize. The default is PAGE_SIZE.

# 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 is a new experimental scheduler that has been designed for SMP,
# but will work just fine on UP too. Users of this scheduler should expect
# some hicups and be prepaired to provide feedback.

# 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.
options ADAPTIVE_MUTEXES
# SMP Debugging Options:
#
# MUTEX_DEBUG enables various extra assertions in the mutex code.
# WITNESS enables the witness code which detects deadlocks and cycles
# during locking operations.
# WITNESS_DDB causes the witness code to drop into the kernel debugger if
# a lock heirarchy violation occurs or if locks are held when going to
# sleep.
# WITNESS_SKIPSPIN disables the witness checks on spin mutexes.
options MUTEX_DEBUG
options WITNESS
options WITNESS_DDB
options WITNESS_SKIPSPIN
#
# MUTEX_PROFILING - Profiling mutual exclusion locks (mutexes). This
# records four numbers for each acquisition point (identified by
# source file name and line number): longest time held, total time held,
# number of non-recursive acquisitions, and average time held. Measurements
# are made and stored in nanoseconds (using nanotime(9)), but are presented
# in microseconds, which should be sufficient for the locks which actually
# want this (those that are held long and / or often). The MUTEX_PROFILING
# option has the following sysctl namespace for controlling and viewing its
# operation:
#
# debug.mutex.prof.enable - enable / disable profiling
# debug.mutex.prof.acquisitions - number of mutex acquisitions held
# debug.mutex.prof.records - number of acquisition points recorded
# debug.mutex.prof.maxrecords - max number of acquisition points
# debug.mutex.prof.rejected - number of rejections (due to full table)
# debug.mutex.prof.hashsize - hash size
# debug.mutex.prof.collisions - number of hash collisions
# debug.mutex.prof.stats - profiling statistics
#
options MUTEX_PROFILING

# 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
# Enable FreeBSD4 compatibility syscalls

#####################################################################
# DEBUGGING OPTIONS
#
# Enable the kernel debugger.
#
options DDB
#
# Use direct symbol lookup routines for ddb instead of the kernel linker
# ones, so that symbols (mostly) work before the kernel linker has been
# initialized. This is not the default because it breaks ddb's lookup of
# symbols in loaded modules.
#
#!options DDB_NOKLDSYM
#
# Print a stack trace of the current thread out on the console for a panic.
#
options DDB_TRACE
#
# 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). 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. 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.
#
options KTR
options KTR_ENTRIES=1024
options KTR_COMPILE=(KTR_INTR|KTR_PROC)
options KTR_MASK=KTR_INTR
options KTR_CPUMASK=0x3
options KTR_VERBOSE
#
# 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 consitute 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 via the Debugger() function 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
# quality assurance purposes (like this file, which the option takes it name
# from.)

# The `ppp' device implements the Point-to-Point Protocol.
# The `bpf' device enables the Berkeley Packet Filter. Be

# feature works properly.
#
# 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:
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.unit="0"

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 Envinronment Services ("ses") and
# SAF-TE ("SCSI Accessable 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.
#
# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
# configuration as the "pass" driver.
