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.

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.
42 #
43 ident LINT

45 #
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 #
51 maxusers 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.

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.

154 #
155 # SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
156 # queue and no cpu affinity which makes it suboptimal for SMP. It has very
157 # good interactivity and priority selection.

173
174 # ADAPTIVE_MUTEXES changes the behavior of blocking mutexes to spin
175 # if the thread that currently owns the mutex is executing on another
176 # CPU. This behaviour is enabled by default, so this option can be used
177 # to disable it.
178 options NO_ADAPTIVE_MUTEXES
179
180 # ADAPTIVE_GIANT causes the Giant lock to also be made adaptive when
181 # running without NO_ADAPTIVE_MUTEXES. Normally, because Giant is assumed
182 # to be held for extended periods, contention on Giant will cause a thread
183 # to sleep rather than spinning.
184 options ADAPTIVE_GIANT

186 # MUTEX_NOINLINE forces mutex operations to call functions to perform each
187 # operation rather than inlining the simple cases. This can be used to

190 # and WITNESS options.

202 # allows interrupt threads to run sooner rather than waiting.
203 # WARNING! Only tested on alpha, amd64, and i386.
204 # FULL_PREEMPTION instructs the kernel to preempt non-realtime kernel
205 # threads. It sole use is to expose race conditions and other
206 # bugs during development. Enabling this option will reduce
207 # performance and increase the frequency of kernel panics by
208 # design. If you aren't sure that you need it then you don't.
209 # Relies on the PREEMPTION option. DON'T TURN THIS ON.
210 # MUTEX_DEBUG enables various extra assertions in the mutex code.
211 # SLEEPQUEUE_PROFILING enables rudimentary profiling of the hash table
212 # used to hold active sleep queues.
213 # TURNSTILE_PROFILING enables rudimentary profiling of the hash table
214 # used to hold active lock queues.
215 # WITNESS enables the witness code which detects deadlocks and cycles
216 # during locking operations.
217 # WITNESS_KDB causes the witness code to drop into the kernel debugger if
218 # a lock hierarchy violation occurs or if locks are held when going to

314 # asynchronously to the thread generating the event. This requires a
315 # pre-allocated store of objects representing trace events. The

327 # trace buffer. KTR_COMPILE defines the mask of events to compile into the

329 # initial value of the ktr_mask variable which determines at runtime what
330 # events to trace. KTR_CPUMASK determines which CPU's log events, with
331 # bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events
332 # to the console by default. This functionality can be toggled via the

355 # called. The intent is that you can set 'INVARIANTS' for single
356 # source files (by changing the source file or specifying it on the
357 # command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you
358 # wish to build a kernel module with 'INVARIANTS', then adding

554 # to the IPv4/IPv6 translation daemon.

557 # specified via ETHER_* options. See ef(4) for details.

559 # The pf packet filter consists of three devices:
560 # The `pf' device provides /dev/pf and the firewall code itself.

565 # The PPP_BSDCOMP option enables support for compress(1) style entire
566 # packet compression, the PPP_DEFLATE is for zlib/gzip style compression.

943 # SCSI DEVICE CONFIGURATION
944
945 # The SCSI subsystem consists of the `base' SCSI code, a number of
946 # high-level SCSI device `type' drivers, and the low-level host-adapter
947 # device drivers. The host adapters are listed in the ISA and PCI
948 # device configuration sections below.
949 #
950 # It is possible to wire down your SCSI devices so that a given bus,
951 # target, and LUN always come on line as the same device unit. In
952 # earlier versions the unit numbers were assigned in the order that
953 # the devices were probed on the SCSI bus. This means that if you
954 # removed a disk drive, you may have had to rewrite your /etc/fstab
955 # file, and also that you had to be careful when adding a new disk
956 # as it may have been probed earlier and moved your device configuration
957 # around. (See also option GEOM_VOL for a different solution to this
958 # problem.)
959
960 # This old behavior is maintained as the default behavior. The unit
961 # assignment begins with the first non-wired down unit for a device
962 # type. For example, if you wire a disk as "da3" then the first
963 # non-wired disk will be assigned da4.
