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

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.

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.

614 # Network interfaces:
615 # The `loop' device is MANDATORY when networking is enabled.
616 # The `ether' device provides generic code to handle
617 # Ethernets; it is MANDATORY when an Ethernet device driver is
618 # configured or token-ring is enabled.
619 # The `vlan' device implements the VLAN tagging of Ethernet frames
620 # according to IEEE 802.1Q. It requires `device miibus'.
621 # The `wlan' device provides generic code to support 802.11
622 # drivers, including host AP mode; it is MANDATORY for the wi,
623 # ath, and awi drivers and will eventually be required by all 802.11 drivers.
624 # The `wlan_wep', `wlan_tkip', and `wlan_ccmp' devices provide
625 # support for WEP, TKIP, and AES-CCMP crypto protocols optionally
626 # used with 802.11 devices that depend on the `wlan' module.
627 # The `wlan_xauth' device provides support for external (i.e. user-mode)
628 # authenticators for use with 802.11 drivers that use the `wlan'
629 # module and support 802.1x and/or WPA security protocols.
630 # The `wlan_acl' device provides a MAC-based access control mechanism
631 # for use with 802.11 drivers operating in ap mode and using the
632 # `wlan' module.
633 # The `fddi' device provides generic code to support FDDI.
634 # The `arcnet' device provides generic code to support Arcnet.
635 # The `sppp' device serves a similar role for certain types
636 # of synchronous PPP links (like `cx', `ar').
637 # The `sl' device implements the Serial Line IP (SLIP) service.
638 # The `ppp' device implements the Point-to-Point Protocol.
639 # The `bpf' device enables the Berkeley Packet Filter. Be
640 # aware of the legal and administrative consequences of enabling this
641 # option. The number of devices determines the maximum number of
642 # simultaneous BPF clients programs runnable. DHCP requires bpf.
643 # The `disc' device implements a minimal network interface,
644 # which throws away all packets sent and never receives any. It is
645 # included for testing and benchmarking purposes.
646 # The `edsc' device implements a minimal Ethernet interface,
647 # which discards all packets sent and receives none.
648 # The `tap' device is a pty-like virtual Ethernet interface
649 # The `tun' device implements (user-)ppp and nos-tun
650 # The `gif' device implements IPv6 over IP4 tunneling,
651 # IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
652 # IPv6 over IPv6 tunneling.
653 # The `gre' device implements two types of IP4 over IP4 tunneling:
654 # GRE and MOBILE, as specified in the RFC1701 and RFC2004.
655 # The XBONEHACK option allows the same pair of addresses to be configured on
656 # multiple gif interfaces.
657 # The `faith' device captures packets sent to it and diverts them
658 # to the IPv4/IPv6 translation daemon.
659 # The `stf' device implements 6to4 encapsulation.
660 # The `ef' device provides support for multiple ethernet frame types
661 # specified via ETHER_* options. See ef(4) for details.
662 #
663 # The pf packet filter consists of three devices:
664 # The `pf' device provides /dev/pf and the firewall code itself.
665 # The `pflog' device provides the pflog0 interface which logs packets.
666 # The `pfsync' device provides the pfsync0 interface used for
667 # synchronization of firewall state tables (over the net).
668 #
669 # The PPP_BSDCOMP option enables support for compress(1) style entire
670 # packet compression, the PPP_DEFLATE is for zlib/gzip style compression.
671 # PPP_FILTER enables code for filtering the ppp data stream and selecting

1052 # SCSI DEVICES
1053
1054 # SCSI DEVICE CONFIGURATION
1055
1056 # The SCSI subsystem consists of the `base' SCSI code, a number of
1057 # high-level SCSI device `type' drivers, and the low-level host-adapter
1058 # device drivers. The host adapters are listed in the ISA and PCI
1059 # device configuration sections below.
1060 #
1061 # It is possible to wire down your SCSI devices so that a given bus,
1062 # target, and LUN always come on line as the same device unit. In
1063 # earlier versions the unit numbers were assigned in the order that
1064 # the devices were probed on the SCSI bus. This means that if you
1065 # removed a disk drive, you may have had to rewrite your /etc/fstab
1066 # file, and also that you had to be careful when adding a new disk
1067 # as it may have been probed earlier and moved your device configuration
1068 # around. (See also option GEOM_VOL for a different solution to this
1069 # problem.)
1070
1071 # This old behavior is maintained as the default behavior. The unit
1072 # assignment begins with the first non-wired down unit for a device
1073 # type. For example, if you wire a disk as "da3" then the first
1074 # non-wired disk will be assigned da4.
1075
1076 # The syntax for wiring down devices is:
1077
1078 hint.scbus.0.at="ahc0"
