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.

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.

142# Options for CPU features.
143#
144# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
145# BlueLightning CPU.  It works only with Cyrix FPU, and this option
146# should not be used with Intel FPU.
147#
148# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
149# CPU if CPU supports it. The default is double-clock mode on
150# BlueLightning CPU box.
151#
152# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
153#
154# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
155# mapped mode.  Default is 2-way set associative mode.
156#
157# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
158# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
159# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
160#
161# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
162# reorder).  This option should not be used if you use memory mapped
163# I/O device(s).
164#
165# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
166#
167# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
168# for i386 machines.
169#
170# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
171# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
172# (no clock delay).
173#
174# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
175# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
176# 1).
177#
178# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
179#
180# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
181# enters suspend mode following execution of HALT instruction.
182#
183# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
184# K5/K6/K6-2 cpus.
185#
186# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
187# flush at hold state.
188#
189# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
190# without cache flush at hold state, and (2) write-back CPU cache on
191# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
192#
193# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
194# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
195# executed.  This should be included for ALL kernels that won't run
196# on a Pentium.
197#
198# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
199# which indicates that the 15-16MB range is *definitely* not being

204# These options may crash your system.
205#
206# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
207# in write-through mode when revision < 2.7.  If revision of Cyrix
208# 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# disk 		da0 at scbus0 target 0 unit 0
716# disk		da1 at scbus3 target 1
717# disk		da2 at scbus2 target 3
718# tape		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.

1011#	0x04	don't use the npx registers to optimize copyin or copyout.
1012#	0x08	use emulator even if hardware FPU is available.
1013# The npx registers are normally used to optimize copying and zeroing when
1014# all of the following conditions are satisfied:
1015#	I586_CPU is an option
1016#	the cpu is an i586 (perhaps not a Pentium)
1017#	the probe for npx0 succeeds
1018#	INT 16 exception handling works.
1019# Then copying and zeroing using the npx registers is normally 30-100% faster.
1020# The flags can be used to control cases where it doesn't work or is slower.
1021# Setting them at boot time using userconfig works right (the optimizations
1022# are not used until later in the bootstrap when npx0 is attached).

1089# The flags fields are used to enable the multi-sector I/O and
1090# the 32BIT I/O modes.  The flags may be used in either the controller
1091# definition or in the individual disk definitions.  The controller
1092# definition is supported for the boot configuration stuff.
1093#
1094# Each drive has a 16 bit flags value defined:
1095#	The low 8 bits are the maximum value for the multi-sector I/O,
1096#	where 0xff defaults to the maximum that the drive can handle.
1097#	The high bit of the 16 bit flags (0x8000) allows probing for
1098#	32 bit transfers.  Bit 14 (0x4000) enables a hack to wake
1099#	up powered-down laptop drives.  Bit 13 (0x2000) allows
1100#	probing for PCI IDE DMA controllers, such as Intel's PIIX
1101#	south bridges. Bit 12 (0x1000) sets LBA mode instead of the
1102#	default CHS mode for accessing the drive. See the wd.4 man page.
1103#
1104# The flags field for the drives can be specified in the controller
1105# specification with the low 16 bits for drive 0, and the high 16 bits
1106# for drive 1.
1107# e.g.:
1108#controller	wdc0	at isa? port IO_WD1 irq 14 flags 0x00ff8004
1109#
1110# specifies that drive 0 will be allowed to probe for 32 bit transfers and
1111# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
1112# allowed to probe for 32 bit transfers, but will allow multi-sector
1113# transfers up to the maximum that the drive supports.
1114#
1115# If you are using a PCI controller that is not running in compatibility
1116# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
1117# such as:
1118#
1119#controller	wdc2	at isa? port 0 irq ? flags 0xa0ffa0ff

1431#    0x0020  Statclock is broken.
1432#    0x0011  Limit APM protocol to 1.1 or 1.0
1433#    0x0010  Limit APM protocol to 1.0
1434#  If apm is omitted, some systems require sysctl -w kern.timecounter.method=1
1435#  for correct timekeeping.

1437# Notes on the spigot:
1438#  The video spigot is at 0xad6.  This port address can not be changed.
1439#  The irq values may only be 10, 11, or 15
1440#  I/O memory is an 8kb region.  Possible values are:
1441#    0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
1442#    The start address must be on an even boundary.
1443#  Add the following option if you want to allow non-root users to be able
1444#  to access the spigot.  This option is not secure because it allows users
1445#  direct access to the I/O page.

1448# Notes on the Comtrol Rocketport driver:
1449#
1450# The exact values used for rp0 depend on how many boards you have
1451# in the system.  The manufacturer's sample configs are listed as:
1452#
1453#   Comtrol Rocketport ISA single card
1454#               device  rp0     at isa? port 0x280
1455#
1456#   If instead you have two ISA cards, one installed at 0x100 and the
1457#   second installed at 0x180, then you should add the following to
1458#   your kernel configuration file:
1459#
1460#               device  rp0     at isa? port 0x100
1461#               device  rp1     at isa? port 0x180
1462#
1463#   For 4 ISA cards, it might be something like this:
1464#
1465#               device  rp0     at isa? port 0x180
1466#               device  rp1     at isa? port 0x100
1467#               device  rp2     at isa? port 0x340
1468#               device  rp3     at isa? port 0x240
1469#
1470#   And for PCI cards, you only need say:
1471#
1472#               device rp0
1473#               device rp1
1474#               ...
1475#   Note: Make sure that any Rocketport PCI devices are specified BEFORE the
1476#   ISA Rocketport devices.
1477
1478# Notes on the Digiboard driver:
1479#
1480# The following flag values have special meanings:
1481#	0x01 - alternate layout of pins (dgb & dgm)
1482#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1483
1484# Notes on the Specialix SI/XIO driver:
1485#  **This is NOT a Specialix supported Driver!**
1486#  The host card is memory, not IO mapped.
1487#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1488#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1489#  The cards can use an IRQ of 11, 12 or 15.

2189# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2190# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2191# The DPT controllers are commonly re-licensed under other brand-names -
2192# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2193# Compaq are actually DPT controllers.
2194#
2195# See sys/dev/dpt for debugging and other subtle options.
2196#   DPT_VERIFY_HINTR        Performs some strict hardware interrupts testing.
2197#                           Only use if you suspect PCI bus corruption problems
2198#   DPT_RESTRICTED_FREELIST Normally, the freelist used by the DPT for queue
2199#                           will grow to accommodate increased use. This growth
2200#                           will NOT shrink.  To restrict the number of queue
2201#                           slots to exactly what the DPT can hold at one time,
2202#                           enable this option.
2203#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2204#                           instruments are enabled.  The tools in
2205#                           /usr/sbin/dpt_* assume these to be enabled.
2206#   DPT_FREELIST_IS_STACK   For optimal L{1,2} CPU cache utilization, enable
2207#                           this option.  Otherwise, the transaction queue is
2208#                           a LIFO.  I cannot measure the performance gain.
2209#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
2210#                           If you ant the driver to handle timeouts, enable
2211#                           this option.  If your system is very busy, this
2212#                           option will create more trouble than solve.
2213#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
2214#                           wait when timing out with the above option.
2215#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
2216#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
2217#                           any interrupt that got lost.  Seems to help in some
2218#                           DPT-firmware/Motherboard combinations.  Minimal
2219#                           cost, great benefit.
2220#  DPT_RESET_HBA            Make "reset" actually reset the controller
2221#                           instead of fudging it.  Only enable this if you
2222#			    are 100% certain you need it.
2223#  DPT_SHUTDOWN_SLEEP       Reset controller if a request take more than
2224#                           this number of seconds.  Do NOT enable this
2225#			    unless you are really, really, really certain
2226#			    you need it.  You are advised to call Simon (the
2227#			    driver author) before setting it, and NEVER,
