642 # SCSI DEVICE CONFIGURATION
644 # The SCSI subsystem consists of the `base' SCSI code, a number of
645 # high-level SCSI device `type' drivers, and the low-level host-adapter
646 # device drivers. The host adapters are listed in the ISA and PCI
647 # device configuration sections below.
649 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
650 # that a given bus, target, and LUN always come on line as the same
651 # device unit. In earlier versions the unit numbers were assigned
652 # in the order that the devices were probed on the SCSI bus. This
653 # means that if you removed a disk drive, you may have had to rewrite
654 # your /etc/fstab file, and also that you had to be careful when adding
655 # a new disk as it may have been probed earlier and moved your device
656 # configuration around.
658 # This old behavior is maintained as the default behavior. The unit
659 # assignment begins with the first non-wired down unit for a device
660 # type. For example, if you wire a disk as "da3" then the first
661 # non-wired disk will be assigned da4.
663 # The syntax for wiring down devices is:
665 # controller scbus0 at ahc0 # Single bus device
666 # controller scbus1 at ahc1 bus 0 # Single bus device
667 # controller scbus3 at ahc2 bus 0 # Twin bus device
668 # controller scbus2 at ahc2 bus 1 # Twin bus device
669 # disk da0 at scbus0 target 0 unit 0
670 # disk da1 at scbus3 target 1

1897 # The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1898 # These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1899 # The DPT controllers are commonly re-licensed under other brand-names -
1900 # some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1901 # Compaq are actually DPT controllers.
1903 # See sys/dev/dpt for debugging and other subtle options.
1904 # DPT_VERIFY_HINTR Performs some strict hardware interrupts testing.
1905 # Only use if you suspect PCI bus corruption problems
1906 # DPT_RESTRICTED_FREELIST Normally, the freelisat used by the DPT for queue
1907 # will grow to accomodate increased use. This growth
1908 # will NOT shrink. To restrict the number of queue
1909 # slots to exactly what the DPT can hold at one time,
1910 # enable this option.
1911 # DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1912 # instruments are enabled. The tools in
1913 # /usr/sbin/dpt_* assume these to be enabled.
1914 # DPT_FREELIST_IS_STACK For optimal L{1,2} CPU cache utilization, enable
1915 # this option. Otherwise, the transaction queue is
1916 # a LIFO. I cannot measure the performance gain.
1917 # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1918 # If you ant the driver to handle timeouts, enable
1919 # this option. If your system is very busy, this
1920 # option will create more trouble than solve.
1921 # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1922 # wait when timing out with the above option.
1923 # DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1924 # DPT_LOST_IRQ When enabled, will try, once per second, to catch
1925 # any interrupt that got lost. Seems to help in some
1926 # DPT-firmware/Motherboard combinations. Minimal
1927 # cost, great benefit.
1928 # DPT_RESET_HBA Make "reset" actually reset the controller
1929 # instead of fudging it. Only enable this if you
1930 # are 100% certain you need it.
1931 # DPT_SHUTDOWN_SLEEP Reset controller if a request take more than
1932 # this number of seconds. Do NOT enable this
1933 # unless you are really, really, really certain
1934 # you need it. You are advised to call Simon (the
1935 # driver author) before setting it, and NEVER,
1936 # EVER set it to less than 300s (5 minutes).
