3 # NOTES -- Lines that can be cut/pasted into kernel and hints configs.
5 # Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
6 # 'makeoptions', 'hints', etc. go into the kernel configuration that you
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.
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:
22 # Large block comments should begin and end with a line containing only a
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.
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 "#!".
40 # This is the ``identification'' of the kernel. Usually this should
41 # be the same as the name of your kernel.
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.
54 # The `makeoptions' parameter allows variables to be passed to the
55 # generated Makefile in the build area.
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).
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.

71 # MODULES_OVERRIDE can be used to limit modules built to a specific list.

1037 # SCSI DEVICE CONFIGURATION
1039 # The SCSI subsystem consists of the `base' SCSI code, a number of
1040 # high-level SCSI device `type' drivers, and the low-level host-adapter
1041 # device drivers. The host adapters are listed in the ISA and PCI
1042 # device configuration sections below.
1044 # It is possible to wire down your SCSI devices so that a given bus,
1045 # target, and LUN always come on line as the same device unit. In
1046 # earlier versions the unit numbers were assigned in the order that
1047 # the devices were probed on the SCSI bus. This means that if you
1048 # removed a disk drive, you may have had to rewrite your /etc/fstab
1049 # file, and also that you had to be careful when adding a new disk
1050 # as it may have been probed earlier and moved your device configuration
1051 # around. (See also option GEOM_VOL for a different solution to this
1054 # This old behavior is maintained as the default behavior. The unit
1055 # assignment begins with the first non-wired down unit for a device
1056 # type. For example, if you wire a disk as "da3" then the first
1057 # non-wired disk will be assigned da4.
1059 # The syntax for wiring down devices is:
