179# forgotten to enable them.
180#
181# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
182# BlueLightning CPU. It works only with Cyrix FPU, and this option
183# should not be used with Intel FPU.
184#
185# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
186# CPU if CPU supports it. The default is double-clock mode on
187# BlueLightning CPU box.
188#
189# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
190#
191# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
192# mapped mode. Default is 2-way set associative mode.
193#
194# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
195# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
196# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
197#
198# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables

202# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.

204# CPU_FASTER_5X86_FPU enables faster FPU exception handler.

216#
217# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
218# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
219# 1).
220#
221# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
222# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
223# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
224#
225# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

227# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
228# enters suspend mode following execution of HALT instruction.
229#
230# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
231#
232# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
233# K5/K6/K6-2 cpus.
234#
235# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
236# flush at hold state.
237#
238# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
239# without cache flush at hold state, and (2) write-back CPU cache on
240# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
241#
242# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
243# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
244# executed. This option is only needed if I586_CPU is also defined,
245# and should be included for any non-Pentium CPU that defines it.
246#
247# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
248# which indicates that the 15-16MB range is *definitely* not being

348# as a string from snprintf rather than as a string and up to 5 argument
349# pointers. KTR_ENTRIES defines the number of entries in the circular trace

354# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events

882
883# SCSI DEVICE CONFIGURATION
884
885# The SCSI subsystem consists of the `base' SCSI code, a number of
886# high-level SCSI device `type' drivers, and the low-level host-adapter
887# device drivers. The host adapters are listed in the ISA and PCI
888# device configuration sections below.
889#
890# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
891# that a given bus, target, and LUN always come on line as the same
892# device unit. In earlier versions the unit numbers were assigned
893# in the order that the devices were probed on the SCSI bus. This
894# means that if you removed a disk drive, you may have had to rewrite
895# your /etc/fstab file, and also that you had to be careful when adding
896# a new disk as it may have been probed earlier and moved your device
897# configuration around.
898
899# This old behavior is maintained as the default behavior. The unit
900# assignment begins with the first non-wired down unit for a device
901# type. For example, if you wire a disk as "da3" then the first
902# non-wired disk will be assigned da4.
903
904# The syntax for wiring down devices is:

2114# Notes on the Comtrol Rocketport driver:

2118#

2121# Comtrol Rocketport ISA single card
2122# hints.rp.0.at="isa"

2124#
2125# If instead you have two ISA cards, one installed at 0x100 and the

2127# your kernel probe hints:
2128# hints.rp.0.at="isa"

2130# hints.rp.1.at="isa"
2131# hints.rp.1.port="0x180"

2141# hints.rp.3.port="0x240"
2142#
2143# And for PCI cards, you need no hints.
2144
2145# Notes on the Digiboard driver:
2146#
2147# The following flag values have special meanings in dgb:
2148# 0x01 - alternate layout of pins
2149# 0x02 - use the windowed PC/Xe in 64K mode
2150
2151# Notes on the Specialix SI/XIO driver:
2152# The host card is memory, not IO mapped.
2153# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2154# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2155# The cards can use an IRQ of 11, 12 or 15.
2156
2157# Notes on the Sony Programmable I/O controller
2158# This is a temporary driver that should someday be replaced by something
2159# that hooks into the ACPI layer. The device is hooked to the PIIX4's
2160# General Device 10 decoder, which means you have to fiddle with PCI
2161# registers to map it in, even though it is otherwise treated here as
2162# an ISA device. At the moment, the driver polls, although the device
2163# is capable of generating interrupts. It largely undocumented.
2164# The port location in the hint is where you WANT the device to be
2165# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2166# is the only thing truly supported, but aparently a fair percentage
2167# of the Vaio extra features are controlled by this device.
2168

2170# See src/i386/isa/README.stl for complete instructions.
2171# This is version 0.0.5alpha, unsupported by Stallion.
2172# The stl driver has a secondary IO port hard coded at 0x280. You need
2173# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2174# The "flags" and "msize" settings on the stli driver depend on the board:
