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.
42 #
43 ident LINT
44
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 # To statically compile in device wiring instead of /boot/device.hints
54 #hints "LINT.hints" # Default places to look for devices.
55
56 # Use the following to compile in values accessible to the kernel
57 # through getenv() (or kenv(1) in userland). The format of the file
58 # is 'variable=value', see kenv(1)
59 #
60 #env "LINT.env"
61
62 #
63 # The `makeoptions' parameter allows variables to be passed to the
64 # generated Makefile in the build area.
65 #
66 # CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
67 # after most other flags. Here we use it to inhibit use of non-optimal
68 # gcc built-in functions (e.g., memcmp).
69 #
70 # DEBUG happens to be magic.
71 # The following is equivalent to 'config -g KERNELNAME' and creates
72 # 'kernel.debug' compiled with -g debugging as well as a normal
73 # 'kernel'. Use 'make install.debug' to install the debug kernel
74 # but that isn't normally necessary as the debug symbols are not loaded
75 # by the kernel and are not useful there anyway.
76 #
77 # KERNEL can be overridden so that you can change the default name of your
78 # kernel.
79 #
80 # MODULES_OVERRIDE can be used to limit modules built to a specific list.
81 #

90 # FreeBSD processes are subject to certain limits to their consumption
91 # of system resources. See getrlimit(2) for more details. Each
92 # resource limit has two values, a "soft" limit and a "hard" limit.
93 # The soft limits can be modified during normal system operation, but
94 # the hard limits are set at boot time. Their default values are
95 # in sys/<arch>/include/vmparam.h. There are two ways to change them:
96 #
97 # 1. Set the values at kernel build time. The options below are one
98 # way to allow that limit to grow to 1GB. They can be increased
99 # further by changing the parameters:
100 #
101 # 2. In /boot/loader.conf, set the tunables kern.maxswzone,
102 # kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
103 # kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
104 #
105 # The options in /boot/loader.conf override anything in the kernel
106 # configuration file. See the function init_param1 in

196 # Scheduler options:
197 #
198 # Specifying one of SCHED_4BSD or SCHED_ULE is mandatory. These options
199 # select which scheduler is compiled in.
200 #
201 # SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
202 # queue and no CPU affinity which makes it suboptimal for SMP. It has very
203 # good interactivity and priority selection.
204 #
205 # SCHED_ULE provides significant performance advantages over 4BSD on many
206 # workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues
207 # and scheduler locks. It also has a stronger notion of interactivity
208 # which leads to better responsiveness even on uniprocessor machines. This
209 # is the default scheduler.
210 #
211 # SCHED_STATS is a debugging option which keeps some stats in the sysctl

1213 # SCSI DEVICE CONFIGURATION
1214
1215 # The SCSI subsystem consists of the `base' SCSI code, a number of
1216 # high-level SCSI device `type' drivers, and the low-level host-adapter
1217 # device drivers. The host adapters are listed in the ISA and PCI
1218 # device configuration sections below.
1219 #
1220 # It is possible to wire down your SCSI devices so that a given bus,
1221 # target, and LUN always come on line as the same device unit. In
1222 # earlier versions the unit numbers were assigned in the order that
1223 # the devices were probed on the SCSI bus. This means that if you
1224 # removed a disk drive, you may have had to rewrite your /etc/fstab
1225 # file, and also that you had to be careful when adding a new disk
1226 # as it may have been probed earlier and moved your device configuration
1227 # around. (See also option GEOM_VOL for a different solution to this
1228 # problem.)
1229
1230 # This old behavior is maintained as the default behavior. The unit
1231 # assignment begins with the first non-wired down unit for a device
1232 # type. For example, if you wire a disk as "da3" then the first
1233 # non-wired disk will be assigned da4.
1234
1235 # The syntax for wiring down devices is:
