83# resource limit has two values, a "soft" limit and a "hard" limit.
84# The soft limits can be modified during normal system operation, but
85# the hard limits are set at boot time. Their default values are
86# in sys/<arch>/include/vmparam.h. There are two ways to change them:

88# 1. Set the values at kernel build time. The options below are one
89# way to allow that limit to grow to 1GB. They can be increased
90# further by changing the parameters:

92# 2. In /boot/loader.conf, set the tunables kern.maxswzone,
93# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
94# kern.dflssiz, kern.maxssiz and kern.sgrowsiz.

715# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''. It
716# depends on IPFIREWALL if compiled into the kernel.

1036# SCSI DEVICES
1037
1038# SCSI DEVICE CONFIGURATION
1039
1040# The SCSI subsystem consists of the `base' SCSI code, a number of
1041# high-level SCSI device `type' drivers, and the low-level host-adapter
1042# device drivers. The host adapters are listed in the ISA and PCI
1043# device configuration sections below.
1044#
1045# It is possible to wire down your SCSI devices so that a given bus,
1046# target, and LUN always come on line as the same device unit. In
1047# earlier versions the unit numbers were assigned in the order that
1048# the devices were probed on the SCSI bus. This means that if you
1049# removed a disk drive, you may have had to rewrite your /etc/fstab
1050# file, and also that you had to be careful when adding a new disk
1051# as it may have been probed earlier and moved your device configuration
1052# around. (See also option GEOM_VOL for a different solution to this
1053# problem.)
1054
1055# This old behavior is maintained as the default behavior. The unit
1056# assignment begins with the first non-wired down unit for a device
1057# type. For example, if you wire a disk as "da3" then the first
1058# non-wired disk will be assigned da4.

2052# Notes on the Comtrol Rocketport driver:
2053#
2054# The exact values used for rp0 depend on how many boards you have
2055# in the system. The manufacturer's sample configs are listed as:
2056#

2062#
2063# If instead you have two ISA cards, one installed at 0x100 and the
2064# second installed at 0x180, then you should add the following to
2065# your kernel probe hints:

2068# hint.rp.1.at="isa"
2069# hint.rp.1.port="0x180"
2070#
2071# For 4 ISA cards, it might be something like this:
2072# hint.rp.0.at="isa"
2073# hint.rp.0.port="0x180"

584# Network interfaces:
585# The `loop' device is MANDATORY when networking is enabled.
586# The `ether' device provides generic code to handle
587# Ethernets; it is MANDATORY when an Ethernet device driver is
588# configured or token-ring is enabled.
589# The `vlan' device implements the VLAN tagging of Ethernet frames
590# according to IEEE 802.1Q. It requires `device miibus'.
591# The `wlan' device provides generic code to support 802.11
592# drivers, including host AP mode; it is MANDATORY for the wi,
593# ath, and awi drivers and will eventually be required by all 802.11 drivers.
594# The `wlan_wep', `wlan_tkip', and `wlan_ccmp' devices provide
595# support for WEP, TKIP, and AES-CCMP crypto protocols optionally
596# used with 802.11 devices that depend on the `wlan' module.
597# The `wlan_xauth' device provides support for external (i.e. user-mode)
598# authenticators for use with 802.11 drivers that use the `wlan'
599# module and support 802.1x and/or WPA security protocols.
600# The `wlan_acl' device provides a MAC-based access control mechanism
601# for use with 802.11 drivers operating in ap mode and using the
602# `wlan' module.
603# The `fddi' device provides generic code to support FDDI.
604# The `arcnet' device provides generic code to support Arcnet.

606# of synchronous PPP links (like `cx', `ar').
607# The `sl' device implements the Serial Line IP (SLIP) service.
608# The `ppp' device implements the Point-to-Point Protocol.
609# The `bpf' device enables the Berkeley Packet Filter. Be
610# aware of the legal and administrative consequences of enabling this
611# option. The number of devices determines the maximum number of
612# simultaneous BPF clients programs runnable. DHCP requires bpf.
613# The `disc' device implements a minimal network interface,
614# which throws away all packets sent and never receives any. It is
615# included for testing purposes. This shows up as the `ds' interface.
616# The `tap' device is a pty-like virtual Ethernet interface
617# The `tun' device implements (user-)ppp and nos-tun
618# The `gif' device implements IPv6 over IP4 tunneling,
619# IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
620# IPv6 over IPv6 tunneling.
621# The `gre' device implements two types of IP4 over IP4 tunneling:
622# GRE and MOBILE, as specified in the RFC1701 and RFC2004.
623# The XBONEHACK option allows the same pair of addresses to be configured on
624# multiple gif interfaces.
625# The `faith' device captures packets sent to it and diverts them
626# to the IPv4/IPv6 translation daemon.
627# The `stf' device implements 6to4 encapsulation.
628# The `ef' device provides support for multiple ethernet frame types
629# specified via ETHER_* options. See ef(4) for details.
630#
631# The pf packet filter consists of three devices:
632# The `pf' device provides /dev/pf and the firewall code itself.
633# The `pflog' device provides the pflog0 interface which logs packets.
634# The `pfsync' device provides the pfsync0 interface used for
635# synchronization of firewall state tables (over the net).
636#
637# The PPP_BSDCOMP option enables support for compress(1) style entire
638# packet compression, the PPP_DEFLATE is for zlib/gzip style compression.

710# means that you won't get stuck if the kernel and /sbin/ipfw binary get
711# out of sync.

713# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''. It
714# depends on IPFIREWALL if compiled into the kernel.
715#

1034# SCSI DEVICES
1035
1036# SCSI DEVICE CONFIGURATION
1037
1038# The SCSI subsystem consists of the `base' SCSI code, a number of
1039# high-level SCSI device `type' drivers, and the low-level host-adapter
1040# device drivers. The host adapters are listed in the ISA and PCI
1041# device configuration sections below.
1042#
1043# It is possible to wire down your SCSI devices so that a given bus,
1044# target, and LUN always come on line as the same device unit. In
1045# earlier versions the unit numbers were assigned in the order that
1046# the devices were probed on the SCSI bus. This means that if you
1047# removed a disk drive, you may have had to rewrite your /etc/fstab
1048# file, and also that you had to be careful when adding a new disk
1049# as it may have been probed earlier and moved your device configuration
1050# around. (See also option GEOM_VOL for a different solution to this
1051# problem.)
1052
1053# This old behavior is maintained as the default behavior. The unit
1054# assignment begins with the first non-wired down unit for a device
1055# type. For example, if you wire a disk as "da3" then the first
1056# non-wired disk will be assigned da4.
1057
1058# The syntax for wiring down devices is:

1480# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
1481# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1482# The DPT controllers are commonly re-licensed under other brand-names -
1483# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1484# Compaq are actually DPT controllers.
1485#
1486# See src/sys/dev/dpt for debugging and other subtle options.
1487# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1488# instruments are enabled. The tools in
1489# /usr/sbin/dpt_* assume these to be enabled.
1490# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1491# If you ant the driver to handle timeouts, enable
1492# this option. If your system is very busy, this
1493# option will create more trouble than solve.
1494# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1495# wait when timing out with the above option.
1496# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1497# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1498# any interrupt that got lost. Seems to help in some
1499# DPT-firmware/Motherboard combinations. Minimal
1500# cost, great benefit.
1501# DPT_RESET_HBA Make "reset" actually reset the controller
