40# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
41# after most other flags.  Here we use it to inhibit use of non-optimal

43#
44# DEBUG happens to be magic.
45# The following is equivalent to 'config -g KERNELNAME' and creates
46# 'kernel.debug' compiled with -g debugging as well as a normal
47# 'kernel'.  Use 'make install.debug' to install the debug kernel
48# but that isn't normally necessary as the debug symbols are not loaded
49# by the kernel and are not useful there anyway.
50#
51# KERNEL can be overridden so that you can change the default name of your

54# MODULES_OVERRIDE can be used to limit modules built to a specific list.

56# INSTALLSTRIPPED can be set to cause installkernel to install stripped
57# kernels and modules rather than a kernel and modules with debug symbols.

342#  The `bpf' pseudo-device enables the Berkeley Packet Filter.  Be

347#  which throws away all packets sent and never receives any.  It is

350#  The `gif' pseudo-device implements IPv6 over IP4 tunneling,
351#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and

355#  The `faith' pseudo-device captures packets sent to it and diverts them

691
692# SCSI DEVICE CONFIGURATION
693
694# The SCSI subsystem consists of the `base' SCSI code, a number of
695# high-level SCSI device `type' drivers, and the low-level host-adapter
696# device drivers.  The host adapters are listed in the ISA and PCI
697# device configuration sections below.
698#
699# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
700# that a given bus, target, and LUN always come on line as the same
701# device unit.  In earlier versions the unit numbers were assigned
702# in the order that the devices were probed on the SCSI bus.  This
703# means that if you removed a disk drive, you may have had to rewrite
704# your /etc/fstab file, and also that you had to be careful when adding
705# a new disk as it may have been probed earlier and moved your device
706# configuration around.
707
708# This old behavior is maintained as the default behavior.  The unit
709# assignment begins with the first non-wired down unit for a device
710# type.  For example, if you wire a disk as "da3" then the first
711# non-wired disk will be assigned da4.
712
713# The syntax for wiring down devices is:
714
715# device	scbus0 at ahc0		# Single bus device
716# device	scbus1 at ahc1 bus 0	# Single bus device
717# device	scbus3 at ahc2 bus 0	# Twin bus device
718# device	scbus2 at ahc2 bus 1	# Twin bus device
719# device 	da0 at scbus0 target 0 unit 0
720# device	da1 at scbus3 target 1
721# device	da2 at scbus2 target 3
722# device	sa1 at scbus1 target 6
723# device	cd
724
725# "units" (SCSI logical unit number) that are not specified are
726# treated as if specified as LUN 0.
727
728# All SCSI devices allocate as many units as are required.

1927# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1928# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1929# The DPT controllers are commonly re-licensed under other brand-names -
1930# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1931# Compaq are actually DPT controllers.
1932#
1933# See src/sys/dev/raid/dpt for debugging and other subtle options.
1934#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1935#                           instruments are enabled.  The tools in
1936#                           /usr/sbin/dpt_* assume these to be enabled.
1937#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
1938#                           If you ant the driver to handle timeouts, enable
1939#                           this option.  If your system is very busy, this
1940#                           option will create more trouble than solve.
1941#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
1942#                           wait when timing out with the above option.
1943#  DPT_DEBUG_xxxx           These are controllable from sys/dev/raid/dpt/dpt.h
1944#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
1945#                           any interrupt that got lost.  Seems to help in some
1946#                           DPT-firmware/Motherboard combinations.  Minimal
1947#                           cost, great benefit.
1948#  DPT_RESET_HBA            Make "reset" actually reset the controller
1949#                           instead of fudging it.  Only enable this if you
1950#			    are 100% certain you need it.
