168#
169# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
170# BlueLightning CPU. It works only with Cyrix FPU, and this option
171# should not be used with Intel FPU.
172#
173# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
174# CPU if CPU supports it. The default is double-clock mode on
175# BlueLightning CPU box.
176#
177# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
178#
179# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
180# mapped mode. Default is 2-way set associative mode.
181#
182# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
183# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
184# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
185#
186# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
187# reorder). This option should not be used if you use memory mapped
188# I/O device(s).
189#
190# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
191#
192# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
193# for i386 machines.
194#
195# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of

197# (no clock delay).
198#
199# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used
200# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
201# The default value is 5.
202#
203# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
204# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
205# 1).
206#
207# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
208# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
209# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
210#
211# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
212#
213# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
214# enters suspend mode following execution of HALT instruction.
215#
216# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
217# K5/K6/K6-2 cpus.
218#
219# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
220# flush at hold state.
221#
222# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
223# without cache flush at hold state, and (2) write-back CPU cache on
224# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
225#
226# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
227# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
228# executed. This option is only needed if I586_CPU is also defined,
229# and should be included for any non-Pentium CPU that defines it.
230#
231# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
232# which indicates that the 15-16MB range is *definitely* not being
233# occupied by an ISA memory hole.
234#

238#
239# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
240# in write-through mode when revision < 2.7. If revision of Cyrix
241# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

336# as a string from snprintf rather than as a string and up to 5 argument
337# pointers. KTR_ENTRIES defines the number of entries in the circular trace
338# buffer. KTR_COMPILE defines the mask of events to compile into the kernel
339# as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the
340# initial value of the ktr_mask variable which determines at runtime what
341# events to trace. KTR_CPUMASK determines which CPU's log events, with
342# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events
343# to the console by default. This functionality can be toggled via the

809
810# SCSI DEVICE CONFIGURATION
811
812# The SCSI subsystem consists of the `base' SCSI code, a number of
813# high-level SCSI device `type' drivers, and the low-level host-adapter
814# device drivers. The host adapters are listed in the ISA and PCI
815# device configuration sections below.
816#
817# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
818# that a given bus, target, and LUN always come on line as the same
819# device unit. In earlier versions the unit numbers were assigned
820# in the order that the devices were probed on the SCSI bus. This
821# means that if you removed a disk drive, you may have had to rewrite
822# your /etc/fstab file, and also that you had to be careful when adding
823# a new disk as it may have been probed earlier and moved your device
824# configuration around.
825
826# This old behavior is maintained as the default behavior. The unit
827# assignment begins with the first non-wired down unit for a device
828# type. For example, if you wire a disk as "da3" then the first
829# non-wired disk will be assigned da4.
830
831# The syntax for wiring down devices is:
832

2509# a KLD module.
2510# The STREAMS network emulation code can also be compiled statically or as a
2511# module. If loaded as a module, it must be loaded before the svr4 module
2512# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2513# the `streams' device must be configured into any kernel which also
2514# specifies COMPAT_SVR4. It is possible to have a statically-configured
2515# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2516# script understands that it doesn't need to load the `streams' module under
2517# those circumstances.
