32# The `makeoptions' parameter allows variables to be passed to the
33# generated Makefile in the build area.
34#
35# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
36# after most other flags.  Here we use it to inhibit use of non-optimal
37# gcc builtin functions (e.g., memcmp).
38#
39# DEBUG happens to be magic.
40# The following is equivalent to 'config -g KERNELNAME' and creates
41# 'kernel.debug' compiled with -g debugging as well as a normal
42# 'kernel'.  Use 'make install.debug' to install the debug kernel
43# but that isn't normally necessary as the debug symbols are not loaded
44# by the kernel and are not useful there anyway.
45#
46# KERNEL can be overridden so that you can change the default name of your
47# kernel.

54# Certain applications can grow to be larger than the 128M limit
55# that FreeBSD initially imposes.  Below are some options to
56# allow that limit to grow to 256MB, and can be increased further
57# with changing the parameters.  MAXDSIZ is the maximum that the
58# limit can be set to, and the DFLDSIZ is the default value for
59# the limit.  You might want to set the default lower than the
60# max, and explicitly set the maximum with a shell command for processes
61# that regularly exceed the limit like INND.

67# BLKDEV_IOSIZE sets the default block size used in user block
68# device I/O.  Note that this value will be overriden by the label
69# when specifying a block device from a label with a non-0

144# Options for CPU features.
145#
146# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
147# BlueLightning CPU.  It works only with Cyrix FPU, and this option
148# should not be used with Intel FPU.
149#
150# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
151# CPU if CPU supports it. The default is double-clock mode on
152# BlueLightning CPU box.
153#
154# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
155#
156# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
157# mapped mode.  Default is 2-way set associative mode.
158#
159# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
160# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
161# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
162#
163# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
164# reorder).  This option should not be used if you use memory mapped
165# I/O device(s).
166#
167# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
168#
169# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
170# for i386 machines.
171#
172# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
173# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
174# (no clock delay).
175#
176# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
177# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
178# 1).
179#
180# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
181#
182# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
183# enters suspend mode following execution of HALT instruction.
184#
185# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
186# K5/K6/K6-2 cpus.
187#
188# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
189# flush at hold state.
190#
191# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
192# without cache flush at hold state, and (2) write-back CPU cache on
193# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
194#
195# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
196# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
197# executed.  This should be included for ALL kernels that won't run
198# on a Pentium.
199#
200# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
201# which indicates that the 15-16MB range is *definitely* not being
202# occupied by an ISA memory hole.
203#
204# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
205# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
206# These options may crash your system.
207#
208# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
209# in write-through mode when revision < 2.7.  If revision of Cyrix
210# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

686# SCSI DEVICES
687
688# SCSI DEVICE CONFIGURATION
689
690# The SCSI subsystem consists of the `base' SCSI code, a number of
691# high-level SCSI device `type' drivers, and the low-level host-adapter
692# device drivers.  The host adapters are listed in the ISA and PCI
693# device configuration sections below.
694#
695# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
696# that a given bus, target, and LUN always come on line as the same
697# device unit.  In earlier versions the unit numbers were assigned
698# in the order that the devices were probed on the SCSI bus.  This
699# means that if you removed a disk drive, you may have had to rewrite
700# your /etc/fstab file, and also that you had to be careful when adding
701# a new disk as it may have been probed earlier and moved your device
702# configuration around.
703
704# This old behavior is maintained as the default behavior.  The unit
705# assignment begins with the first non-wired down unit for a device
706# type.  For example, if you wire a disk as "da3" then the first
707# non-wired disk will be assigned da4.
708
709# The syntax for wiring down devices is:
710
711# controller	scbus0 at ahc0		# Single bus device
712# controller	scbus1 at ahc1 bus 0	# Single bus device
713# controller	scbus3 at ahc2 bus 0	# Twin bus device
714# controller	scbus2 at ahc2 bus 1	# Twin bus device
715# device 	da0 at scbus0 target 0 unit 0
716# device	da1 at scbus3 target 1
717# device	da2 at scbus2 target 3
718# device	sa1 at scbus1 target 6
719# device	cd0 at scbus?
720
721# "units" (SCSI logical unit number) that are not specified are
722# treated as if specified as LUN 0.
723
724# All SCSI devices allocate as many units as are required.

1082# The flags fields are used to enable the multi-sector I/O and
1083# the 32BIT I/O modes.  The flags may be used in either the controller
1084# definition or in the individual disk definitions.  The controller
1085# definition is supported for the boot configuration stuff.
1086#
1087# Each drive has a 16 bit flags value defined:
1088#	The low 8 bits are the maximum value for the multi-sector I/O,
1089#	where 0xff defaults to the maximum that the drive can handle.
1090#	The high bit of the 16 bit flags (0x8000) allows probing for
1091#	32 bit transfers.  Bit 14 (0x4000) enables a hack to wake
1092#	up powered-down laptop drives.  Bit 13 (0x2000) allows
1093#	probing for PCI IDE DMA controllers, such as Intel's PIIX
1094#	south bridges. Bit 12 (0x1000) sets LBA mode instead of the
1095#	default CHS mode for accessing the drive. See the wd.4 man page.
1096#
1097# The flags field for the drives can be specified in the controller
1098# specification with the low 16 bits for drive 0, and the high 16 bits
1099# for drive 1.
1100# e.g.:
1101#controller	wdc0	at isa? port IO_WD1 irq 14 flags 0x00ff8004
1102#
1103# specifies that drive 0 will be allowed to probe for 32 bit transfers and
1104# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
1105# allowed to probe for 32 bit transfers, but will allow multi-sector
1106# transfers up to the maximum that the drive supports.
1107#
1108# If you are using a PCI controller that is not running in compatibility
1109# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
1110# such as:
1111#
1112#controller	wdc2	at isa? port 0 irq ? flags 0xa0ffa0ff

1441# Notes on the Comtrol Rocketport driver:
1442#
1443# The exact values used for rp0 depend on how many boards you have
1444# in the system.  The manufacturer's sample configs are listed as:
1445#
1446#   Comtrol Rocketport ISA single card
1447#               device  rp0     at isa? port 0x280
1448#
1449#   If instead you have two ISA cards, one installed at 0x100 and the
1450#   second installed at 0x180, then you should add the following to
1451#   your kernel configuration file:
1452#
1453#               device  rp0     at isa? port 0x100
1454#               device  rp1     at isa? port 0x180
1455#
1456#   For 4 ISA cards, it might be something like this:
1457#
1458#               device  rp0     at isa? port 0x180
1459#               device  rp1     at isa? port 0x100
1460#               device  rp2     at isa? port 0x340
1461#               device  rp3     at isa? port 0x240
1462#
1463#   And for PCI cards, you only need say:
1464#
1465#               device rp0
1466#               device rp1
1467#               ...
1468#   Note: Make sure that any Rocketport PCI devices are specified BEFORE the
1469#   ISA Rocketport devices.

1471# Notes on the Digiboard driver:
1472#
1473# The following flag values have special meanings:
1474#	0x01 - alternate layout of pins (dgb & dgm)
1475#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1476
1477# Notes on the Specialix SI/XIO driver:
1478#  **This is NOT a Specialix supported Driver!**
1479#  The host card is memory, not IO mapped.
1480#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1481#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1482#  The cards can use an IRQ of 11, 12 or 15.

2213# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2214# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2215# The DPT controllers are commonly re-licensed under other brand-names -
2216# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2217# Compaq are actually DPT controllers.
2218#
2219# See sys/dev/dpt for debugging and other subtle options.
2220#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2221#                           instruments are enabled.  The tools in
2222#                           /usr/sbin/dpt_* assume these to be enabled.
2223#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
2224#                           If you ant the driver to handle timeouts, enable
2225#                           this option.  If your system is very busy, this
2226#                           option will create more trouble than solve.
2227#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
2228#                           wait when timing out with the above option.
2229#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
2230#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
2231#                           any interrupt that got lost.  Seems to help in some
2232#                           DPT-firmware/Motherboard combinations.  Minimal
2233#                           cost, great benefit.
2234#  DPT_RESET_HBA            Make "reset" actually reset the controller
2235#                           instead of fudging it.  Only enable this if you
2236#			    are 100% certain you need it.
