1# $FreeBSD: head/sys/conf/NOTES 134383 2004-08-27 15:16:24Z andre $ 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# 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. 70# 71# MODULES_OVERRIDE can be used to limit modules built to a specific list. 72# 73makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 74#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 75#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 76# Only build Linux API modules and plus those parts of the sound system I need. 77#makeoptions MODULES_OVERRIDE="linux sound/sound sound/driver/maestro3" 78makeoptions DESTDIR=/tmp 79 80 81# 82# Certain applications can grow to be larger than the 512M limit 83# that FreeBSD initially imposes. Below are some options to 84# allow that limit to grow to 1GB, and can be increased further 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 90# that regularly exceed the limit like INND. 91# 92options MAXDSIZ=(1024UL*1024*1024) 93options MAXSSIZ=(128UL*1024*1024) 94options DFLDSIZ=(1024UL*1024*1024) 95 96# 97# BLKDEV_IOSIZE sets the default block size used in user block 98# device I/O.

To be more 299# SMP-friendly, KTRACE uses a worker thread to process most trace events 300# asynchronously to the thread generating the event. This requires a 301# pre-allocated store of objects representing trace events. The 302# KTRACE_REQUEST_POOL option specifies the initial size of this store. 303# The size of the pool can be adjusted both at boottime and runtime via 304# the kern.ktrace_request_pool tunable and sysctl. 305# 306options KTRACE #kernel tracing 307options KTRACE_REQUEST_POOL=101 308 309# 310# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 311# has no userland interface aside from a few sysctl's. It is enabled with 312# the KTR option. KTR_ENTRIES defines the number of entries in the circular 313# trace buffer. KTR_COMPILE defines the mask of events to compile into the 314# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 315# initial value of the ktr_mask variable which determines at runtime what 316# events to trace. KTR_CPUMASK determines which CPU's log events, with 317# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 318# to the console by default. This functionality can be toggled via the 319# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 320# 321options KTR 322options KTR_ENTRIES=1024 323options KTR_COMPILE=(KTR_INTR|KTR_PROC) 324options KTR_MASK=KTR_INTR 325options KTR_CPUMASK=0x3 326options KTR_VERBOSE 327 328# 329# The INVARIANTS option is used in a number of source files to enable 330# extra sanity checking of internal structures. This support is not 331# enabled by default because of the extra time it would take to check 332# for these conditions, which can only occur as a result of 333# programming errors. 334# 335options INVARIANTS 336 337# 338# The INVARIANT_SUPPORT option makes us compile in support for 339# verifying some of the internal structures. It is a prerequisite for 340# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 341# called. The intent is that you can set 'INVARIANTS' for single 342# source files (by changing the source file or specifying it on the 343# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 344# wish to build a kernel module with 'INVARIANTS', then adding 345# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 346# infrastructure without the added overhead. 347# 348options INVARIANT_SUPPORT 349 350# 351# The DIAGNOSTIC option is used to enable extra debugging information 352# from some parts of the kernel.
