3# NOTES -- Lines that can be cut/pasted into kernel and hints configs.
4#
5# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
6# 'makeoptions', 'hints', etc. go into the kernel configuration that you
7# run config(8) with.
8#
9# Lines that begin with 'hint.' are NOT for config(8), they go into your
10# hints file. See /boot/device.hints and/or the 'hints' config(8) directive.
11#
12# Please use ``make LINT'' to create an old-style LINT file if you want to
13# do kernel test-builds.
14#
15# This file contains machine independent kernel configuration notes. For
16# machine dependent notes, look in /sys/<arch>/conf/NOTES.

20# NOTES conventions and style guide:
21#
22# Large block comments should begin and end with a line containing only a
23# comment character.
24#
25# To describe a particular object, a block comment (if it exists) should
26# come first. Next should come device, options, and hints lines in that
27# order. All device and option lines must be described by a comment that
28# doesn't just expand the device or option name. Use only a concise
29# comment on the same line if possible. Very detailed descriptions of
30# devices and subsystems belong in man pages.
31#
32# A space followed by a tab separates 'options' from an option name. Two
33# spaces followed by a tab separate 'device' from a device name. Comments
34# after an option or device should use one space after the comment character.
35# To comment out a negative option that disables code and thus should not be
36# enabled for LINT builds, precede 'options' with "#!".
37#
38
39#
40# This is the ``identification'' of the kernel. Usually this should
41# be the same as the name of your kernel.

46# The `maxusers' parameter controls the static sizing of a number of
47# internal system tables by a formula defined in subr_param.c.
48# Omitting this parameter or setting it to 0 will cause the system to
49# auto-size based on physical memory.
50#
51maxusers 10
52
53#
54# The `makeoptions' parameter allows variables to be passed to the
55# generated Makefile in the build area.
56#
57# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
58# after most other flags. Here we use it to inhibit use of non-optimal
59# gcc builtin functions (e.g., memcmp).
60#
61# DEBUG happens to be magic.
62# The following is equivalent to 'config -g KERNELNAME' and creates
63# 'kernel.debug' compiled with -g debugging as well as a normal
64# 'kernel'. Use 'make install.debug' to install the debug kernel
65# but that isn't normally necessary as the debug symbols are not loaded
66# by the kernel and are not useful there anyway.
67#
68# KERNEL can be overridden so that you can change the default name of your
69# kernel.
70#
71# MODULES_OVERRIDE can be used to limit modules built to a specific list.

82# Certain applications can grow to be larger than the 512M limit
83# that FreeBSD initially imposes. Below are some options to
84# allow that limit to grow to 1GB, and can be increased further
85# with changing the parameters. MAXDSIZ is the maximum that the
86# limit can be set to, and the DFLDSIZ is the default value for
87# the limit. MAXSSIZ is the maximum that the stack limit can be
88# set to. You might want to set the default lower than the max,
89# and explicitly set the maximum with a shell command for processes
90# that regularly exceed the limit like INND.

98# device I/O. Note that this value will be overridden by the label
99# when specifying a block device from a label with a non-0

149# Scheduler options:
150#
151# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory. These options
152# select which scheduler is compiled in.
153#
154# SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
155# queue and no cpu affinity which makes it suboptimal for SMP. It has very
156# good interactivity and priority selection.
157#
158# SCHED_ULE is a new scheduler that has been designed for SMP and has some
159# advantages for UP as well. It is intended to replace the 4BSD scheduler
160# over time.

168# SMP enables building of a Symmetric MultiProcessor Kernel.
169
170# Mandatory:
171options SMP # Symmetric MultiProcessor Kernel
172
173# ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin
174# if the thread that currently owns the mutex is executing on another
175# CPU. This behaviour is enabled by default, so this option can be used
176# to disable it.
177options NO_ADAPTIVE_MUTEXES
178
179# ADAPTIVE_GIANT causes the Giant lock to also be made adaptive when
180# running without NO_ADAPTIVE_MUTEXES. Normally, because Giant is assumed
181# to be held for extended periods, contention on Giant will cause a thread
182# to sleep rather than spinning.
183options ADAPTIVE_GIANT
184
185# MUTEX_NOINLINE forces mutex operations to call functions to perform each
186# operation rather than inlining the simple cases. This can be used to
187# shrink the size of the kernel text segment. Note that this behavior is
188# already implied by the INVARIANT_SUPPORT, INVARIANTS, MUTEX_PROFILING,
189# and WITNESS options.
190options MUTEX_NOINLINE
191
192# MUTEX_WAKE_ALL changes the mutex unlock algorithm to wake all waiters
193# when a contested mutex is released rather than just awaking the highest
194# priority waiter.
195options MUTEX_WAKE_ALL
196
197# SMP Debugging Options:
198#
199# FULL_PREEMPTION instructs the kernel to preempt non-realtime kernel
200# threads. It sole use is to expose race conditions and other
201# bugs during development. Enabling this option will reduce
202# performance and increase the frequency of kernel panics by
203# design. If you aren't sure that you need it then you don't.
204# DON'T TURN THIS ON.
205# MUTEX_DEBUG enables various extra assertions in the mutex code.
206# SLEEPQUEUE_PROFILING enables rudimentary profiling of the hash table
207# used to hold active sleep queues.
208# TURNSTILE_PROFILING enables rudimentary profiling of the hash table
209# used to hold active lock queues.
210# WITNESS enables the witness code which detects deadlocks and cycles
211# during locking operations.
212# WITNESS_KDB causes the witness code to drop into the kernel debugger if
213# a lock hierarchy violation occurs or if locks are held when going to
214# sleep.
215# WITNESS_SKIPSPIN disables the witness checks on spin mutexes.

239# Implement system calls compatible with 4.3BSD and older versions of
240# FreeBSD. You probably do NOT want to remove this as much current code
241# still relies on the 4.3 emulation. Note that some architectures that

298# KTRACE enables the system-call tracing facility ktrace(2). To be more
299# SMP-friendly, KTRACE uses a worker thread to process most trace events
300# asynchronously to the thread generating the event. This requires a
301# pre-allocated store of objects representing trace events. The
302# KTRACE_REQUEST_POOL option specifies the initial size of this store.
303# The size of the pool can be adjusted both at boottime and runtime via
304# the kern.ktrace_request_pool tunable and sysctl.

309#
310# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it
311# has no userland interface aside from a few sysctl's. It is enabled with
312# the KTR option. KTR_ENTRIES defines the number of entries in the circular
313# trace buffer. KTR_COMPILE defines the mask of events to compile into the
314# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the
315# initial value of the ktr_mask variable which determines at runtime what
316# events to trace. KTR_CPUMASK determines which CPU's log events, with
317# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events
318# to the console by default. This functionality can be toggled via the
319# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined.

329# The INVARIANTS option is used in a number of source files to enable
330# extra sanity checking of internal structures. This support is not

338# The INVARIANT_SUPPORT option makes us compile in support for
339# verifying some of the internal structures. It is a prerequisite for
340# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be
341# called. The intent is that you can set 'INVARIANTS' for single
342# source files (by changing the source file or specifying it on the
343# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you
344# wish to build a kernel module with 'INVARIANTS', then adding
345# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary
346# infrastructure without the added overhead.

362# impossible) scenarios.

367# RESTARTABLE_PANICS allows one to continue from a panic as if it were
368# a call to the debugger via the Debugger() function instead. It is only
369# useful if a kernel debugger is present. To restart from a panic, reset
370# the panicstr variable to NULL and continue execution. This option is
371# for development use only and should NOT be used in production systems
372# to "workaround" a panic.

917# SCSI DEVICES
918
919# SCSI DEVICE CONFIGURATION
920
921# The SCSI subsystem consists of the `base' SCSI code, a number of
922# high-level SCSI device `type' drivers, and the low-level host-adapter
923# device drivers. The host adapters are listed in the ISA and PCI
924# device configuration sections below.
925#
926# It is possible to wire down your SCSI devices so that a given bus,
927# target, and LUN always come on line as the same device unit. In
928# earlier versions the unit numbers were assigned in the order that
929# the devices were probed on the SCSI bus. This means that if you
930# removed a disk drive, you may have had to rewrite your /etc/fstab
931# file, and also that you had to be careful when adding a new disk
932# as it may have been probed earlier and moved your device configuration
933# around. (See also option GEOM_VOL for a different solution to this
934# problem.)
935
936# This old behavior is maintained as the default behavior. The unit
937# assignment begins with the first non-wired down unit for a device
938# type. For example, if you wire a disk as "da3" then the first
939# non-wired disk will be assigned da4.
940
941# The syntax for wiring down devices is:
942
