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.

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

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

179#
180# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

186# K5/K6/K6-2 cpus.

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

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.

727# SCSI DEVICES
728
729# SCSI DEVICE CONFIGURATION
730
731# The SCSI subsystem consists of the `base' SCSI code, a number of
732# high-level SCSI device `type' drivers, and the low-level host-adapter
733# device drivers.  The host adapters are listed in the ISA and PCI
734# device configuration sections below.
735#
736# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
737# that a given bus, target, and LUN always come on line as the same
738# device unit.  In earlier versions the unit numbers were assigned
739# in the order that the devices were probed on the SCSI bus.  This
740# means that if you removed a disk drive, you may have had to rewrite
741# your /etc/fstab file, and also that you had to be careful when adding
742# a new disk as it may have been probed earlier and moved your device
743# configuration around.
744
745# This old behavior is maintained as the default behavior.  The unit
746# assignment begins with the first non-wired down unit for a device
747# type.  For example, if you wire a disk as "da3" then the first
748# non-wired disk will be assigned da4.
749
750# The syntax for wiring down devices is:
751
752# device	scbus0 at ahc0		# Single bus device
753# device	scbus1 at ahc1 bus 0	# Single bus device
754# device	scbus3 at ahc2 bus 0	# Twin bus device
755# device	scbus2 at ahc2 bus 1	# Twin bus device
756# device 	da0 at scbus0 target 0 unit 0
757# device	da1 at scbus3 target 1
758# device	da2 at scbus2 target 3
759# device	sa1 at scbus1 target 6
760# device	cd
761
762# "units" (SCSI logical unit number) that are not specified are
763# treated as if specified as LUN 0.
764
765# All SCSI devices allocate as many units as are required.

1448# Notes on the Digiboard driver:
1449#
1450# The following flag values have special meanings:
1451#	0x01 - alternate layout of pins (dgb & dgm)
1452#	0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1453
1454# Notes on the Specialix SI/XIO driver:
1455#  **This is NOT a Specialix supported Driver!**
1456#  The host card is memory, not IO mapped.
1457#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1458#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1459#  The cards can use an IRQ of 11, 12 or 15.
