15 # These directives are mandatory. The machine directive specifies the
16 # platform and the machine_arch directive specifies the cpu architecture.
23 # This is the ``identification'' of the kernel. Usually this should
24 # be the same as the name of your kernel.
29 # The `maxusers' parameter controls the static sizing of a number of
30 # internal system tables by a formula defined in subr_param.c. Setting
31 # maxusers to 0 will cause the system to auto-size based on physical
37 # The `makeoptions' parameter allows variables to be passed to the
38 # generated Makefile in the build area.
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
42 # gcc builtin functions (e.g., memcmp).
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.
51 # KERNEL can be overridden so that you can change the default name of your

57 # kernels and modules rather than a kernel and modules with debug symbols.

619 # SCSI DEVICE CONFIGURATION
621 # The SCSI subsystem consists of the `base' SCSI code, a number of
622 # high-level SCSI device `type' drivers, and the low-level host-adapter
623 # device drivers. The host adapters are listed in the ISA and PCI
624 # device configuration sections below.
626 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
627 # that a given bus, target, and LUN always come on line as the same
628 # device unit. In earlier versions the unit numbers were assigned
629 # in the order that the devices were probed on the SCSI bus. This
630 # means that if you removed a disk drive, you may have had to rewrite
631 # your /etc/fstab file, and also that you had to be careful when adding
632 # a new disk as it may have been probed earlier and moved your device
633 # configuration around.
635 # This old behavior is maintained as the default behavior. The unit
636 # assignment begins with the first non-wired down unit for a device
637 # type. For example, if you wire a disk as "da3" then the first
638 # non-wired disk will be assigned da4.
640 # The syntax for wiring down devices is:
642 # device scbus0 at ahc0 # Single bus device
643 # device scbus1 at ahc1 bus 0 # Single bus device
644 # device scbus3 at ahc2 bus 0 # Twin bus device
645 # device scbus2 at ahc2 bus 1 # Twin bus device
646 # device da0 at scbus0 target 0 unit 0
647 # device da1 at scbus3 target 1
648 # device da2 at scbus2 target 3
649 # device sa1 at scbus1 target 6
652 # "units" (SCSI logical unit number) that are not specified are
653 # treated as if specified as LUN 0.
655 # All SCSI devices allocate as many units as are required.

1877 # The 'asr' driver provides support for current DPT/Adaptec SCSI RAID
1878 # controllers (SmartRAID V and VI and later).
1879 # These controllers require the CAM infrastructure.
1883 # The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1884 # These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1885 # The DPT controllers are commonly re-licensed under other brand-names -
1886 # some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1887 # Compaq are actually DPT controllers.
1889 # See src/sys/dev/raid/dpt for debugging and other subtle options.
1890 # DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1891 # instruments are enabled. The tools in
1892 # /usr/sbin/dpt_* assume these to be enabled.
1893 # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1894 # If you ant the driver to handle timeouts, enable
1895 # this option. If your system is very busy, this
1896 # option will create more trouble than solve.
1897 # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1898 # wait when timing out with the above option.
1899 # DPT_DEBUG_xxxx These are controllable from sys/dev/raid/dpt/dpt.h
1900 # DPT_LOST_IRQ When enabled, will try, once per second, to catch
1901 # any interrupt that got lost. Seems to help in some
1902 # DPT-firmware/Motherboard combinations. Minimal
1903 # cost, great benefit.
1904 # DPT_RESET_HBA Make "reset" actually reset the controller
1905 # instead of fudging it. Only enable this if you
1906 # are 100% certain you need it.
