# $FreeBSD$ # # NOTES -- Lines that can be cut/pasted into kernel and hints configs. # # Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers', # 'makeoptions', 'hints', etc. go into the kernel configuration that you # run config(8) with. # # Lines that begin with 'hint.' are NOT for config(8), they go into your # hints file. See /boot/device.hints and/or the 'hints' config(8) directive. # # Please use ``make LINT'' to create an old-style LINT file if you want to # do kernel test-builds. # # This file contains machine independent kernel configuration notes. For # machine dependent notes, look in /sys//conf/NOTES. # # # NOTES conventions and style guide: # # Large block comments should begin and end with a line containing only a # comment character. # # To describe a particular object, a block comment (if it exists) should # come first. Next should come device, options, and hints lines in that # order. All device and option lines must be described by a comment that # doesn't just expand the device or option name. Use only a concise # comment on the same line if possible. Very detailed descriptions of # devices and subsystems belong in manpages. # # A space followed by a tab separates 'option' from an option name. Two # spaces followed by a tab separate 'device' from a device name. Comments # after an option or device should use one space after the comment character. # To comment out a negative option that disables code and thus should not be # enabled for LINT builds, precede 'option' with "#!". # # # This is the ``identification'' of the kernel. Usually this should # be the same as the name of your kernel. # ident LINT # # The `maxusers' parameter controls the static sizing of a number of # internal system tables by a formula defined in subr_param.c. # Omitting this parameter or setting it to 0 will cause the system to # auto-size based on physical memory. # maxusers 10 # # The `makeoptions' parameter allows variables to be passed to the # generated Makefile in the build area. # # CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} # after most other flags. Here we use it to inhibit use of non-optimal # gcc builtin functions (e.g., memcmp). # # DEBUG happens to be magic. # The following is equivalent to 'config -g KERNELNAME' and creates # 'kernel.debug' compiled with -g debugging as well as a normal # 'kernel'. Use 'make install.debug' to install the debug kernel # but that isn't normally necessary as the debug symbols are not loaded # by the kernel and are not useful there anyway. # # KERNEL can be overridden so that you can change the default name of your # kernel. # # MODULES_OVERRIDE can be used to limit modules built to a specific list. # makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. #makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols #makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" # Only build Linux API modules and plus those parts of the sound system I need. #makeoptions MODULES_OVERRIDE="linux sound/snd sound/pcm sound/driver/maestro3" makeoptions DESTDIR=/tmp # # Certain applications can grow to be larger than the 512M limit # that FreeBSD initially imposes.

In earlier versions the unit numbers were assigned # in the order that the devices were probed on the SCSI bus. This # means that if you removed a disk drive, you may have had to rewrite # your /etc/fstab file, and also that you had to be careful when adding # a new disk as it may have been probed earlier and moved your device # configuration around. # This old behavior is maintained as the default behavior.
