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.

53# To statically compile in device wiring instead of /boot/device.hints
54#hints		"LINT.hints"		# Default places to look for devices.

56# Use the following to compile in values accessible to the kernel
57# through getenv() (or kenv(1) in userland). The format of the file
58# is 'variable=value', see kenv(1)
59#
60#env		"LINT.env"
61
62#
63# The `makeoptions' parameter allows variables to be passed to the
64# generated Makefile in the build area.
65#
66# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
67# after most other flags.  Here we use it to inhibit use of non-optimal
68# gcc built-in functions (e.g., memcmp).
69#
70# DEBUG happens to be magic.
71# The following is equivalent to 'config -g KERNELNAME' and creates
72# 'kernel.debug' compiled with -g debugging as well as a normal
73# 'kernel'.  Use 'make install.debug' to install the debug kernel
74# but that isn't normally necessary as the debug symbols are not loaded
75# by the kernel and are not useful there anyway.
76#
77# KERNEL can be overridden so that you can change the default name of your
78# kernel.
79#
80# MODULES_OVERRIDE can be used to limit modules built to a specific list.

90# FreeBSD processes are subject to certain limits to their consumption
91# of system resources.  See getrlimit(2) for more details.  Each
92# resource limit has two values, a "soft" limit and a "hard" limit.
93# The soft limits can be modified during normal system operation, but
94# the hard limits are set at boot time.  Their default values are
95# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
96#
97# 1.  Set the values at kernel build time.  The options below are one
98#     way to allow that limit to grow to 1GB.  They can be increased
99#     further by changing the parameters:
100#
101# 2.  In /boot/loader.conf, set the tunables kern.maxswzone,
102#     kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
103#     kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
104#
105# The options in /boot/loader.conf override anything in the kernel

195# Scheduler options:
196#
197# Specifying one of SCHED_4BSD or SCHED_ULE is mandatory.  These options
198# select which scheduler is compiled in.
199#
200# SCHED_4BSD is the historical, proven, BSD scheduler.  It has a global run
201# queue and no CPU affinity which makes it suboptimal for SMP.  It has very
202# good interactivity and priority selection.
203#
204# SCHED_ULE provides significant performance advantages over 4BSD on many
205# workloads on SMP machines.  It supports cpu-affinity, per-cpu runqueues
206# and scheduler locks.  It also has a stronger notion of interactivity
207# which leads to better responsiveness even on uniprocessor machines.  This
208# is the default scheduler.
209#
210# SCHED_STATS is a debugging option which keeps some stats in the sysctl
211# tree at 'kern.sched.stats' and is useful for debugging scheduling decisions.

1199# SCSI DEVICES
1200
1201# SCSI DEVICE CONFIGURATION
1202
1203# The SCSI subsystem consists of the `base' SCSI code, a number of
1204# high-level SCSI device `type' drivers, and the low-level host-adapter
1205# device drivers.  The host adapters are listed in the ISA and PCI
1206# device configuration sections below.
1207#
1208# It is possible to wire down your SCSI devices so that a given bus,
1209# target, and LUN always come on line as the same device unit.  In
1210# earlier versions the unit numbers were assigned in the order that
1211# the devices were probed on the SCSI bus.  This means that if you
1212# removed a disk drive, you may have had to rewrite your /etc/fstab
1213# file, and also that you had to be careful when adding a new disk
1214# as it may have been probed earlier and moved your device configuration
1215# around.  (See also option GEOM_VOL for a different solution to this
1216# problem.)
1217
1218# This old behavior is maintained as the default behavior.  The unit
1219# assignment begins with the first non-wired down unit for a device
1220# type.  For example, if you wire a disk as "da3" then the first
1221# non-wired disk will be assigned da4.
1222
1223# The syntax for wiring down devices is:

1256# The ses driver drives SCSI Environment Services ("ses") and
1257# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices.
1258#
1259# The pt driver drives SCSI Processor devices.
1260#
1261# The sg driver provides a passthrough API that is compatible with the
1262# Linux SG driver.  It will work in conjunction with the COMPAT_LINUX
1263# option to run linux SG apps.  It can also stand on its own and provide
1264# source level API compatibility for porting apps to FreeBSD.
1265#
1266# Target Mode support is provided here but also requires that a SIM
1267# (SCSI Host Adapter Driver) provide support as well.
1268#
1269# The targ driver provides target mode support as a Processor type device.
1270# It exists to give the minimal context necessary to respond to Inquiry
1271# commands. There is a sample user application that shows how the rest
1272# of the command support might be done in /usr/share/examples/scsi_target.
1273#
1274# The targbh driver provides target mode support and exists to respond
1275# to incoming commands that do not otherwise have a logical unit assigned
1276# to them.

2315#                              sanity checking and possible increase of
2316#                              verbosity.
2317#
2318# SND_DIAGNOSTIC               Similar in a spirit of INVARIANTS/DIAGNOSTIC,

2320#
2321# SND_FEEDER_MULTIFORMAT       By default, only 16/32 bit feeders are compiled
2322#                              in. This options enable most feeder converters
2323#                              except for 8bit. WARNING: May bloat the kernel.
2324#
2325# SND_FEEDER_FULL_MULTIFORMAT  Ditto, but includes 8bit feeders as well.

2328#                              as much as possible (the default trying to

2336# SND_OLDSTEREO                Only 2 channels are allowed, effectively
2337#                              disabling multichannel processing.
