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).

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.

This release supports all the extensions 629# including many drafts (most about to become RFC's). 630# It is the reference implementation of SCTP 631# and is quite well tested. 632# 633# Note YOU MUST have both INET and INET6 defined. 634# You don't have to enable V6, but SCTP is 635# dual stacked and so far we have not torn apart 636# the V6 and V4.. since an association can span 637# both a V6 and V4 address at the SAME time :-) 638# 639options SCTP 640# There are bunches of options: 641# this one turns on all sorts of 642# nastily printing that you can 643# do. It's all controlled by a 644# bit mask (settable by socket opt and 645# by sysctl). Including will not cause 646# logging until you set the bits.. but it 647# can be quite verbose.. so without this 648# option we don't do any of the tests for 649# bits and prints.. which makes the code run 650# faster.. if you are not debugging don't use. 651options SCTP_DEBUG 652# 653# This option turns off the CRC32c checksum. Basically, 654# you will not be able to talk to anyone else who 655# has not done this. Its more for experimentation to 656# see how much CPU the CRC32c really takes. Most new 657# cards for TCP support checksum offload.. so this 658# option gives you a "view" into what SCTP would be 659# like with such an offload (which only exists in 660# high in iSCSI boards so far). With the new 661# splitting 8's algorithm its not as bad as it used 662# to be.. but it does speed things up try only 663# for in a captured lab environment :-) 664options SCTP_WITH_NO_CSUM 665# 666 667# 668# All that options after that turn on specific types of 669# logging. You can monitor CWND growth, flight size 670# and all sorts of things. Go look at the code and 671# see. I have used this to produce interesting 672# charts and graphs as well :-> 673# 674# I have not yet committed the tools to get and print 675# the logs, I will do that eventually .. before then 676# if you want them send me an email rrs@freebsd.org 677# You basically must have ktr(4) enabled for these 678# and you then set the sysctl to turn on/off various 679# logging bits.

Details of the exact nature of the bug are sketchy, but some can be 2112# found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 2113# 6. This option enables this workaround. There is a performance penalty 2114# for this work around, but without it things don't work at all. The DMA 2115# from the card usually bursts 128 bytes, but on the affected CPUs, only 2116# 4 are safe. 2117options AH_RXCFG_SDMAMW_4BYTES 2118#device ath_ar9160 # AR9160 chips 2119#device ath_ar9280 # AR9280 chips 2120#device ath_ar9285 # AR9285 chips 2121device ath_rate_sample # SampleRate tx rate control for ath 2122device bwi # Broadcom BCM430* BCM431* 2123device bwn # Broadcom BCM43xx 2124device malo # Marvell Libertas wireless NICs. 2125device mwl # Marvell 88W8363 802.11n wireless NICs. 2126device mwlfw 2127device ral # Ralink Technology RT2500 wireless NICs. 2128 2129# Use sf_buf(9) interface for jumbo buffers on ti(4) controllers. 2130#options TI_SF_BUF_JUMBO 2131# Turn on the header splitting option for the ti(4) driver firmware.
