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.

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#
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 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.

176# Scheduler options:
177#
178# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory.  These options
179# select which scheduler is compiled in.
180#
181# SCHED_4BSD is the historical, proven, BSD scheduler.  It has a global run
182# queue and no CPU affinity which makes it suboptimal for SMP.  It has very
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#
191# SCHED_STATS is a debugging option which keeps some stats in the sysctl
192# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions.

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

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

1160# SCSI DEVICES
1161
1162# SCSI DEVICE CONFIGURATION
1163
1164# The SCSI subsystem consists of the `base' SCSI code, a number of
1165# high-level SCSI device `type' drivers, and the low-level host-adapter
1166# device drivers.  The host adapters are listed in the ISA and PCI
1167# device configuration sections below.
1168#
1169# It is possible to wire down your SCSI devices so that a given bus,
1170# target, and LUN always come on line as the same device unit.  In
1171# earlier versions the unit numbers were assigned in the order that
1172# the devices were probed on the SCSI bus.  This means that if you
1173# removed a disk drive, you may have had to rewrite your /etc/fstab
1174# file, and also that you had to be careful when adding a new disk
1175# as it may have been probed earlier and moved your device configuration
1176# around.  (See also option GEOM_VOL for a different solution to this
1177# problem.)
1178
1179# This old behavior is maintained as the default behavior.  The unit
1180# assignment begins with the first non-wired down unit for a device
1181# type.  For example, if you wire a disk as "da3" then the first
1182# non-wired disk will be assigned da4.
1183
1184# The syntax for wiring down devices is:

1219#
1220# The pt driver drives SCSI Processor devices.
1221#
1222# The sg driver provides a passthrough API that is compatible with the
1223# Linux SG driver.  It will work in conjunction with the COMPAT_LINUX
1224# option to run linux SG apps.  It can also stand on its own and provide
1225# source level API compatiblity for porting apps to FreeBSD.
1226#
1227# Target Mode support is provided here but also requires that a SIM
1228# (SCSI Host Adapter Driver) provide support as well.
1229#
1230# The targ driver provides target mode support as a Processor type device.
1231# It exists to give the minimal context necessary to respond to Inquiry
1232# commands. There is a sample user application that shows how the rest
1233# of the command support might be done in /usr/share/examples/scsi_target.
1234#
1235# The targbh driver provides target mode support and exists to respond
1236# to incoming commands that do not otherwise have a logical unit assigned
1237# to them.

1569# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1570# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1571# The DPT controllers are commonly re-licensed under other brand-names -
1572# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1573# Compaq are actually DPT controllers.
1574#
1575# See src/sys/dev/dpt for debugging and other subtle options.
1576#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1577#                           instruments are enabled.  The tools in
1578#                           /usr/sbin/dpt_* assume these to be enabled.
1579#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1580#                           If you ant the driver to handle timeouts, enable
1581#                           this option.  If your system is very busy, this
1582#                           option will create more trouble than solve.

1586#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
1587#                           any interrupt that got lost.  Seems to help in some
