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.

12# Please use ``make LINT'' to create an old-style LINT file if you want to
13# do kernel test-builds.

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 manpages.
31#
32# A space followed by a tab separates 'option' 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 'option' with "#!".

255# trace buffer. KTR_COMPILE defines the mask of events to compile into the
256# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the
257# initial value of the ktr_mask variable which determines at runtime what
258# events to trace. KTR_CPUMASK determines which CPU's log events, with
259# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events
260# to the console by default. This functionality can be toggled via the
261# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined.

792# SCSI DEVICES
793
794# SCSI DEVICE CONFIGURATION
795
796# The SCSI subsystem consists of the `base' SCSI code, a number of
797# high-level SCSI device `type' drivers, and the low-level host-adapter
798# device drivers. The host adapters are listed in the ISA and PCI
799# device configuration sections below.
800#
801# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
802# that a given bus, target, and LUN always come on line as the same
803# device unit. In earlier versions the unit numbers were assigned
804# in the order that the devices were probed on the SCSI bus. This
805# means that if you removed a disk drive, you may have had to rewrite
806# your /etc/fstab file, and also that you had to be careful when adding
807# a new disk as it may have been probed earlier and moved your device
808# configuration around.
809
810# This old behavior is maintained as the default behavior. The unit
811# assignment begins with the first non-wired down unit for a device
812# type. For example, if you wire a disk as "da3" then the first
813# non-wired disk will be assigned da4.
814
815# The syntax for wiring down devices is:

261# initial value of the ktr_mask variable which determines at runtime what
262# events to trace. KTR_CPUMASK determines which CPU's log events, with
263# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events

796# SCSI DEVICES
797
798# SCSI DEVICE CONFIGURATION
799
800# The SCSI subsystem consists of the `base' SCSI code, a number of
801# high-level SCSI device `type' drivers, and the low-level host-adapter
802# device drivers. The host adapters are listed in the ISA and PCI
803# device configuration sections below.
804#
805# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
806# that a given bus, target, and LUN always come on line as the same
807# device unit. In earlier versions the unit numbers were assigned
808# in the order that the devices were probed on the SCSI bus. This
809# means that if you removed a disk drive, you may have had to rewrite
810# your /etc/fstab file, and also that you had to be careful when adding
811# a new disk as it may have been probed earlier and moved your device
812# configuration around.
813
814# This old behavior is maintained as the default behavior. The unit
815# assignment begins with the first non-wired down unit for a device
816# type. For example, if you wire a disk as "da3" then the first
817# non-wired disk will be assigned da4.
818
819# The syntax for wiring down devices is:

856#
857#
858# Target Mode support is provided here but also requires that a SIM
859# (SCSI Host Adapter Driver) provide support as well.
860#
861# The targ driver provides target mode support as a Processor type device.
862# It exists to give the minimal context necessary to respond to Inquiry
863# commands. There is a sample user application that shows how the rest
864# of the command support might be done in /usr/share/examples/scsi_target.
865#
866# The targbh driver provides target mode support and exists to respond
867# to incoming commands that do not otherwise have a logical unit assigned
868# to them.
