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.

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 built-in 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.

81 # FreeBSD processes are subject to certain limits to their consumption
82 # of system resources. See getrlimit(2) for more details. Each
83 # resource limit has two values, a "soft" limit and a "hard" limit.
84 # The soft limits can be modified during normal system operation, but
85 # the hard limits are set at boot time. Their default values are
86 # in sys/<arch>/include/vmparam.h. There are two ways to change them:
87 #
88 # 1. Set the values at kernel build time. The options below are one
89 # way to allow that limit to grow to 1GB. They can be increased
90 # further by changing the parameters:
91 #
92 # 2. In /boot/loader.conf, set the tunables kern.maxswzone,
93 # kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
94 # kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
95 #
96 # The options in /boot/loader.conf override anything in the kernel
97 # configuration file. See the function init_param1 in
98 # sys/kern/subr_param.c for more details.

178 # Specifying one of SCHED_4BSD or SCHED_ULE is mandatory. These options
179 # select which scheduler is compiled in.

181 # SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run

183 # good interactivity and priority selection.
184 #
185 # SCHED_ULE provides significant performance advantages over 4BSD on many
186 # workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues
187 # and scheduler locks. It also has a stronger notion of interactivity
188 # which leads to better responsiveness even on uniprocessor machines. This
189 # will eventually become the default scheduler.
190 #

569 # SCTP is a NEW transport protocol defined by
570 # RFC2960 updated by RFC3309 and RFC3758.. and
571 # soon to have a new base RFC and many many more
572 # extensions. This release supports all the extensions
573 # including many drafts (most about to become RFC's).
574 # It is the premeier SCTP implementation in the NET
575 # and is quite well tested.
576 #
577 # Note YOU MUST have both INET and INET6 defined.
578 # you don't have to enable V6, but SCTP is
579 # dual stacked and so far we have not teased apart
580 # the V6 and V4.. since an association can span
581 # both a V6 and V4 address at the SAME time :-)

583 options SCTP
584 # There are bunches of options:
585 # this one turns on all sorts of
586 # nastly printing that you can
587 # do. Its all controled by a
588 # bit mask (settable by socket opt and
589 # by sysctl). Including will not cause
590 # logging until you set the bits.. but it
591 # can be quite verbose.. so without this
592 # option we don't do any of the tests for
593 # bits and prints.. which makes the code run
594 # faster.. if you are not debugging don't use.
595 options SCTP_DEBUG
596 #
597 # This option turns off the CRC32c checksum. Basically
598 # You will not be able to talk to anyone else that
599 # has not done this. Its more for expermentation to
600 # see how much CPU the CRC32c really takes. Most new
601 # cards for TCP support checksum offload.. so this
602 # option gives you a "view" into what SCTP would be
603 # like with such an offload (which only exists in
604 # high in iSCSI boards so far). With the new
605 # splitting 8's algorithm its not as bad as it used
606 # to be.. but it does speed things up try only

619 # the logs, I will do that eventually .. before then
620 # if you want them send me an email rrs@freebsd.org

622 # and you then set the sysctl to turn on/off various

1154 # SCSI DEVICES
1155
1156 # SCSI DEVICE CONFIGURATION
1157
1158 # The SCSI subsystem consists of the `base' SCSI code, a number of
1159 # high-level SCSI device `type' drivers, and the low-level host-adapter
1160 # device drivers. The host adapters are listed in the ISA and PCI
1161 # device configuration sections below.
1162 #
1163 # It is possible to wire down your SCSI devices so that a given bus,
1164 # target, and LUN always come on line as the same device unit. In
1165 # earlier versions the unit numbers were assigned in the order that
1166 # the devices were probed on the SCSI bus. This means that if you
1167 # removed a disk drive, you may have had to rewrite your /etc/fstab
1168 # file, and also that you had to be careful when adding a new disk
1169 # as it may have been probed earlier and moved your device configuration
1170 # around. (See also option GEOM_VOL for a different solution to this
1171 # problem.)
1172
1173 # This old behavior is maintained as the default behavior. The unit
1174 # assignment begins with the first non-wired down unit for a device
1175 # type. For example, if you wire a disk as "da3" then the first
1176 # non-wired disk will be assigned da4.
1177
1178 # The syntax for wiring down devices is:
