1# $FreeBSD: stable/10/sys/conf/NOTES 268091 2014-07-01 13:29:17Z ae $ 2# 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. 17# 18 19# 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# 43ident LINT 44 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# 51maxusers 10 52 53# To statically compile in device wiring instead of /boot/device.hints 54#hints "LINT.hints" # Default places to look for devices. 55 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. 81# 82makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 83#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 84#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 85# Only build ext2fs module plus those parts of the sound system I need. 86#makeoptions MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3" 87makeoptions DESTDIR=/tmp 88 89# 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 106# configuration file.

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. 212# 213options SCHED_4BSD 214options SCHED_STATS 215#options SCHED_ULE 216 217##################################################################### 218# SMP OPTIONS: 219# 220# SMP enables building of a Symmetric MultiProcessor Kernel. 221 222# Mandatory: 223options SMP # Symmetric MultiProcessor Kernel 224 225# MAXCPU defines the maximum number of CPUs that can boot in the system. 226# A default value should be already present, for every architecture. 227options MAXCPU=32 228 229# MAXMEMDOM defines the maximum number of memory domains that can boot in the 230# system.

Including will not cause 644# logging until you set the bits.. but it 645# can be quite verbose.. so without this 646# option we don't do any of the tests for 647# bits and prints.. which makes the code run 648# faster.. if you are not debugging don't use. 649options SCTP_DEBUG 650# 651# This option turns off the CRC32c checksum. Basically, 652# you will not be able to talk to anyone else who 653# has not done this. Its more for experimentation to 654# see how much CPU the CRC32c really takes. Most new 655# cards for TCP support checksum offload.. so this 656# option gives you a "view" into what SCTP would be 657# like with such an offload (which only exists in 658# high in iSCSI boards so far). With the new 659# splitting 8's algorithm its not as bad as it used 660# to be.. but it does speed things up try only 661# for in a captured lab environment :-) 662options SCTP_WITH_NO_CSUM 663# 664 665# 666# All that options after that turn on specific types of 667# logging. You can monitor CWND growth, flight size 668# and all sorts of things. Go look at the code and 669# see. I have used this to produce interesting 670# charts and graphs as well :-> 671# 672# I have not yet committed the tools to get and print 673# the logs, I will do that eventually .. before then 674# if you want them send me an email rrs@freebsd.org 675# You basically must have ktr(4) enabled for these 676# and you then set the sysctl to turn on/off various 677# logging bits.

The DMA 2126# from the card usually bursts 128 bytes, but on the affected CPUs, only 2127# 4 are safe. 2128options AH_RXCFG_SDMAMW_4BYTES 2129#device ath_ar9160 # AR9160 chips 2130#device ath_ar9280 # AR9280 chips 2131#device ath_ar9285 # AR9285 chips 2132device ath_rate_sample # SampleRate tx rate control for ath 2133device bwi # Broadcom BCM430* BCM431* 2134device bwn # Broadcom BCM43xx 2135device malo # Marvell Libertas wireless NICs. 2136device mwl # Marvell 88W8363 802.11n wireless NICs. 2137device mwlfw 2138device ral # Ralink Technology RT2500 wireless NICs. 2139 2140# Use sf_buf(9) interface for jumbo buffers on ti(4) controllers. 2141#options TI_SF_BUF_JUMBO 2142# Turn on the header splitting option for the ti(4) driver firmware.
