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
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 #
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.
72 #

80 #
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.

166 # SCHED_4BSD is the historical, proven, BSD scheduler. It has a global run
167 # queue and no cpu affinity which makes it suboptimal for SMP. It has very
168 # good interactivity and priority selection.
169 #
170 # SCHED_ULE is a new scheduler that has been designed for SMP and has some
171 # advantages for UP as well. It is intended to replace the 4BSD scheduler

216 # FULL_PREEMPTION instructs the kernel to preempt non-realtime kernel
217 # threads. Its sole use is to expose race conditions and other
218 # bugs during development. Enabling this option will reduce
219 # performance and increase the frequency of kernel panics by
220 # design. If you aren't sure that you need it then you don't.
221 # Relies on the PREEMPTION option. DON'T TURN THIS ON.
222 # MUTEX_DEBUG enables various extra assertions in the mutex code.
223 # SLEEPQUEUE_PROFILING enables rudimentary profiling of the hash table
224 # used to hold active sleep queues.
225 # TURNSTILE_PROFILING enables rudimentary profiling of the hash table
226 # used to hold active lock queues.
227 # WITNESS enables the witness code which detects deadlocks and cycles
228 # during locking operations.
229 # WITNESS_KDB causes the witness code to drop into the kernel debugger if
230 # a lock hierarchy violation occurs or if locks are held when going to

577 # Network interfaces:
578 # The `loop' device is MANDATORY when networking is enabled.
579 # The `ether' device provides generic code to handle
580 # Ethernets; it is MANDATORY when an Ethernet device driver is
581 # configured or token-ring is enabled.
582 # The `vlan' device implements the VLAN tagging of Ethernet frames
583 # according to IEEE 802.1Q. It requires `device miibus'.
584 # The `wlan' device provides generic code to support 802.11
585 # drivers, including host AP mode; it is MANDATORY for the wi,
586 # ath, and awi drivers and will eventually be required by all 802.11 drivers.
587 # The `wlan_wep', `wlan_tkip', and `wlan_ccmp' devices provide
588 # support for WEP, TKIP, and AES-CCMP crypto protocols optionally
589 # used with 802.11 devices that depend on the `wlan' module.
590 # The `wlan_xauth' device provides support for external (i.e. user-mode)
591 # authenticators for use with 802.11 drivers that use the `wlan'
592 # module and support 802.1x and/or WPA security protocols.
593 # The `wlan_acl' device provides a MAC-based access control mechanism
594 # for use with 802.11 drivers operating in ap mode and using the
595 # `wlan' module.
596 # The `fddi' device provides generic code to support FDDI.
597 # The `arcnet' device provides generic code to support Arcnet.
598 # The `sppp' device serves a similar role for certain types
599 # of synchronous PPP links (like `cx', `ar').
600 # The `sl' device implements the Serial Line IP (SLIP) service.
601 # The `ppp' device implements the Point-to-Point Protocol.
602 # The `bpf' device enables the Berkeley Packet Filter. Be
603 # aware of the legal and administrative consequences of enabling this
604 # option. The number of devices determines the maximum number of
605 # simultaneous BPF clients programs runnable. DHCP requires bpf.
606 # The `disc' device implements a minimal network interface,
607 # which throws away all packets sent and never receives any. It is
608 # included for testing purposes. This shows up as the `ds' interface.
609 # The `tap' device is a pty-like virtual Ethernet interface
610 # The `tun' device implements (user-)ppp and nos-tun
611 # The `gif' device implements IPv6 over IP4 tunneling,
612 # IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
613 # IPv6 over IPv6 tunneling.
614 # The `gre' device implements two types of IP4 over IP4 tunneling:
615 # GRE and MOBILE, as specified in the RFC1701 and RFC2004.
616 # The XBONEHACK option allows the same pair of addresses to be configured on
617 # multiple gif interfaces.
618 # The `faith' device captures packets sent to it and diverts them
619 # to the IPv4/IPv6 translation daemon.
620 # The `stf' device implements 6to4 encapsulation.
621 # The `ef' device provides support for multiple ethernet frame types
622 # specified via ETHER_* options. See ef(4) for details.
623 #
624 # The pf packet filter consists of three devices:
625 # The `pf' device provides /dev/pf and the firewall code itself.
626 # The `pflog' device provides the pflog0 interface which logs packets.
627 # The `pfsync' device provides the pfsync0 interface used for
628 # synchronization of firewall state tables (over the net).
629 #
630 # The PPP_BSDCOMP option enables support for compress(1) style entire
631 # packet compression, the PPP_DEFLATE is for zlib/gzip style compression.
632 # PPP_FILTER enables code for filtering the ppp data stream and selecting
633 # events for resetting the demand dial activity timer - requires bpf.

1029 # device drivers. The host adapters are listed in the ISA and PCI
1030 # device configuration sections below.
1031 #
1032 # It is possible to wire down your SCSI devices so that a given bus,
1033 # target, and LUN always come on line as the same device unit. In
1034 # earlier versions the unit numbers were assigned in the order that
1035 # the devices were probed on the SCSI bus. This means that if you
1036 # removed a disk drive, you may have had to rewrite your /etc/fstab
1037 # file, and also that you had to be careful when adding a new disk
1038 # as it may have been probed earlier and moved your device configuration
1039 # around. (See also option GEOM_VOL for a different solution to this
1040 # problem.)
1041
1042 # This old behavior is maintained as the default behavior. The unit
