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 manpages.
31#
32# A space followed by a tab separates 'option' 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 'option' with "#!".
37#

39#
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. Setting
48# maxusers to 0 will cause the system to auto-size based on physical
49# memory.
50#
51maxusers 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.

83# that FreeBSD initially imposes. Below are some options to

85# with changing the parameters. MAXDSIZ is the maximum that the
86# limit can be set to, and the DFLDSIZ is the default value for
87# the limit. MAXSSIZ is the maximum that the stack limit can be
88# set to. You might want to set the default lower than the max,
89# and explicitly set the maximum with a shell command for processes

281# trace buffer. KTR_COMPILE defines the mask of events to compile into the
282# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the
283# initial value of the ktr_mask variable which determines at runtime what
284# events to trace. KTR_CPUMASK determines which CPU's log events, with
285# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events
286# to the console by default. This functionality can be toggled via the
287# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined.

843# SCSI DEVICES
844
845# SCSI DEVICE CONFIGURATION
846
847# The SCSI subsystem consists of the `base' SCSI code, a number of
848# high-level SCSI device `type' drivers, and the low-level host-adapter
849# device drivers. The host adapters are listed in the ISA and PCI
850# device configuration sections below.
851#
852# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
853# that a given bus, target, and LUN always come on line as the same
854# device unit. In earlier versions the unit numbers were assigned
855# in the order that the devices were probed on the SCSI bus. This
856# means that if you removed a disk drive, you may have had to rewrite
857# your /etc/fstab file, and also that you had to be careful when adding
858# a new disk as it may have been probed earlier and moved your device
859# configuration around.
860
861# This old behavior is maintained as the default behavior. The unit
862# assignment begins with the first non-wired down unit for a device
863# type. For example, if you wire a disk as "da3" then the first
864# non-wired disk will be assigned da4.
865
866# The syntax for wiring down devices is:
867
868hint.scbus.0.at="ahc0"
869hint.scbus.1.at="ahc1"
870hint.scbus.1.bus="0"

843# SCSI DEVICES
844
845# SCSI DEVICE CONFIGURATION
846
847# The SCSI subsystem consists of the `base' SCSI code, a number of
848# high-level SCSI device `type' drivers, and the low-level host-adapter
849# device drivers. The host adapters are listed in the ISA and PCI
850# device configuration sections below.
851#
852# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
853# that a given bus, target, and LUN always come on line as the same
854# device unit. In earlier versions the unit numbers were assigned
855# in the order that the devices were probed on the SCSI bus. This
856# means that if you removed a disk drive, you may have had to rewrite
857# your /etc/fstab file, and also that you had to be careful when adding
858# a new disk as it may have been probed earlier and moved your device
859# configuration around.
860
861# This old behavior is maintained as the default behavior. The unit
862# assignment begins with the first non-wired down unit for a device
863# type. For example, if you wire a disk as "da3" then the first
864# non-wired disk will be assigned da4.
865
866# The syntax for wiring down devices is:
867
