32# The `makeoptions' parameter allows variables to be passed to the
33# generated Makefile in the build area.  DEBUG happens to be magic.
34# The following is equivalent to 'config -g KERNELNAME' and creates
35# 'kernel.debug' compiled with -g debugging as well as a normal
36# 'kernel'.  Use 'make install.debug' to install the debug kernel
37# but that isn't normally necessary as the debug symbols are not loaded
38# by the kernel and are not useful there anyway.

48# that FreeBSD initially imposes.  Below are some options to
49# allow that limit to grow to 256MB, and can be increased further
50# with changing the parameters.  MAXDSIZ is the maximum that the
51# limit can be set to, and the DFLDSIZ is the default value for
52# the limit.  You might want to set the default lower than the
53# max, and explicitly set the maximum with a shell command for processes
54# that regularly exceed the limit like INND.

115#
116# You must specify at least one CPU (the one you intend to run on);
117# deleting the specification for CPUs you don't need to use may make
118# parts of the system run faster.  This is especially true removing

126#
127# Options for CPU features.
128#
129# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
130# BlueLightning CPU.  It works only with Cyrix FPU, and this option
131# should not be used with Intel FPU.
132#
133# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 
134# CPU if CPU supports it. The default is double-clock mode on
135# BlueLightning CPU box.  
136#
137# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
138#
139# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
140# mapped mode.  Default is 2-way set associative mode.
141#
142# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
143# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
144# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
145#
146# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
147# reorder).  This option should not be used if you use memory mapped
148# I/O device(s). 
149#
150# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
151#
152# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
153# for i386 machines. 
154#
155# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
156# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
157# (no clock delay).
158#
159# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
160# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
161# 1). 
162#
163# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
164#
165# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
166# enters suspend mode following execution of HALT instruction.
167#
168# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
169# K5/K6/K6-2 cpus.
170#
171# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
172# flush at hold state.
173#
174# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
175# without cache flush at hold state, and (2) write-back CPU cache on
176# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
177#
178# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
179# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
180# executed.  This should be included for ALL kernels that won't run
181# on a Pentium.
182#
183# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
184# which indicates that the 15-16MB range is *definitely* not being 
185# occupied by an ISA memory hole.
186#
187# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
188# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
189# These options may crash your system. 
190#
191# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
192# in write-through mode when revision < 2.7.  If revision of Cyrix
193# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

653# SCSI DEVICES
654
655# SCSI DEVICE CONFIGURATION
656
657# The SCSI subsystem consists of the `base' SCSI code, a number of
658# high-level SCSI device `type' drivers, and the low-level host-adapter
659# device drivers.  The host adapters are listed in the ISA and PCI
660# device configuration sections below.
661#
662# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
663# that a given bus, target, and LUN always come on line as the same
664# device unit.  In earlier versions the unit numbers were assigned
665# in the order that the devices were probed on the SCSI bus.  This
666# means that if you removed a disk drive, you may have had to rewrite
667# your /etc/fstab file, and also that you had to be careful when adding
668# a new disk as it may have been probed earlier and moved your device
669# configuration around.
670
671# This old behavior is maintained as the default behavior.  The unit
672# assignment begins with the first non-wired down unit for a device
673# type.  For example, if you wire a disk as "da3" then the first
674# non-wired disk will be assigned da4.
675
676# The syntax for wiring down devices is:
677
678# controller	scbus0 at ahc0		# Single bus device
679# controller	scbus1 at ahc1 bus 0	# Single bus device
680# controller	scbus3 at ahc2 bus 0	# Twin bus device
681# controller	scbus2 at ahc2 bus 1	# Twin bus device
682# disk 		da0 at scbus0 target 0 unit 0
683# disk		da1 at scbus3 target 1
684# disk		da2 at scbus2 target 3
685# tape		sa1 at scbus1 target 6
686# device	cd0 at scbus?
687
688# "units" (SCSI logical unit number) that are not specified are
689# treated as if specified as LUN 0.
690
691# All SCSI devices allocate as many units as are required.

1045# The flags fields are used to enable the multi-sector I/O and
1046# the 32BIT I/O modes.  The flags may be used in either the controller
1047# definition or in the individual disk definitions.  The controller
1048# definition is supported for the boot configuration stuff.
1049#
1050# Each drive has a 16 bit flags value defined:
1051#	The low 8 bits are the maximum value for the multi-sector I/O,
1052#	where 0xff defaults to the maximum that the drive can handle.
1053#	The high bit of the 16 bit flags (0x8000) allows probing for
1054#	32 bit transfers.  Bit 14 (0x4000) enables a hack to wake
1055#	up powered-down laptop drives.  Bit 13 (0x2000) allows
1056#	probing for PCI IDE DMA controllers, such as Intel's PIIX
1057#	south bridges. Bit 12 (0x1000) sets LBA mode instead of the
1058#	default CHS mode for accessing the drive. See the wd.4 man page.
1059#
1060# The flags field for the drives can be specified in the controller
1061# specification with the low 16 bits for drive 0, and the high 16 bits
1062# for drive 1.
1063# e.g.:
1064#controller	wdc0	at isa? port IO_WD1 irq 14 flags 0x00ff8004
1065#
1066# specifies that drive 0 will be allowed to probe for 32 bit transfers and
1067# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
1068# allowed to probe for 32 bit transfers, but will allow multi-sector
1069# transfers up to the maximum that the drive supports.
1070#
1071# If you are using a PCI controller that is not running in compatibility
1072# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
1073# such as:
1074#
1075#controller	wdc2	at isa? port 0 irq ? flags 0xa0ffa0ff

1434# Notes on the Digiboard driver:
1435#
1436# The following flag values have special meanings:
1437#	0x01 - alternate layout of pins (dgb & dgm)
1438#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1439
1440# Notes on the Specialix SI/XIO driver:
1441#  **This is NOT a Specialix supported Driver!**
1442#  The host card is memory, not IO mapped.
1443#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1444#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.

2144# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2145# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2146# The DPT controllers are commonly re-licensed under other brand-names -
2147# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2148# Compaq are actually DPT controllers.
2149#
2150# See sys/dev/dpt for debugging and other subtle options.
2151#   DPT_VERIFY_HINTR        Performs some strict hardware interrupts testing.
2152#                           Only use if you suspect PCI bus corruption problems
2153#   DPT_RESTRICTED_FREELIST Normally, the freelist used by the DPT for queue
2154#                           will grow to accommodate increased use. This growth
2155#                           will NOT shrink.  To restrict the number of queue
2156#                           slots to exactly what the DPT can hold at one time,
2157#                           enable this option.
2158#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2159#                           instruments are enabled.  The tools in 
2160#                           /usr/sbin/dpt_* assume these to be enabled.
2161#   DPT_FREELIST_IS_STACK   For optimal L{1,2} CPU cache utilization, enable
2162#                           this option.  Otherwise, the transaction queue is
2163#                           a LIFO.  I cannot measure the performance gain.
2164#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
2165#                           If you ant the driver to handle timeouts, enable
2166#                           this option.  If your system is very busy, this
2167#                           option will create more trouble than solve.
2168#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
2169#                           wait when timing out with the above option.
2170#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
2171#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
2172#                           any interrupt that got lost.  Seems to help in some
2173#                           DPT-firmware/Motherboard combinations.  Minimal
2174#                           cost, great benefit.
2175#  DPT_RESET_HBA            Make "reset" actually reset the controller
2176#                           instead of fudging it.  Only enable this if you
2177#			    are 100% certain you need it.
2178#  DPT_SHUTDOWN_SLEEP       Reset controller if a request take more than
2179#                           this number of seconds.  Do NOT enable this
2180#			    unless you are really, really, really certain
2181#			    you need it.  You are advised to call Simon (the
2182#			    driver author) before setting it, and NEVER,
2183#			    EVER set it to less than 300s (5 minutes).
