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

212# The default value is 5.
213#
214# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
215# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
216# 1).
217#
218# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
219# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
220# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
221#
222# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
223#
224# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
225# enters suspend mode following execution of HALT instruction.
226#
227# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
228#
229# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
230# K5/K6/K6-2 cpus.
231#
232# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
233# flush at hold state.
234#
235# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
236# without cache flush at hold state, and (2) write-back CPU cache on
237# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
238#
239# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
240# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
241# executed. This option is only needed if I586_CPU is also defined,
242# and should be included for any non-Pentium CPU that defines it.
243#
244# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
245# which indicates that the 15-16MB range is *definitely* not being

344# as a string from snprintf rather than as a string and up to 5 argument
345# pointers. KTR_ENTRIES defines the number of entries in the circular trace
346# buffer. KTR_COMPILE defines the mask of events to compile into the kernel
347# as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the

349# events to trace. KTR_CPUMASK determines which CPU's log events, with
350# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events

349# events to trace. KTR_CPUMASK determines which CPU's log events, with
350# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events

879# SCSI DEVICE CONFIGURATION
880
881# The SCSI subsystem consists of the `base' SCSI code, a number of
882# high-level SCSI device `type' drivers, and the low-level host-adapter
883# device drivers. The host adapters are listed in the ISA and PCI
884# device configuration sections below.
885#
886# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
887# that a given bus, target, and LUN always come on line as the same
888# device unit. In earlier versions the unit numbers were assigned
889# in the order that the devices were probed on the SCSI bus. This
890# means that if you removed a disk drive, you may have had to rewrite
891# your /etc/fstab file, and also that you had to be careful when adding
892# a new disk as it may have been probed earlier and moved your device
893# configuration around.
894
895# This old behavior is maintained as the default behavior. The unit
896# assignment begins with the first non-wired down unit for a device
897# type. For example, if you wire a disk as "da3" then the first
898# non-wired disk will be assigned da4.
899
900# The syntax for wiring down devices is:

2098# Notes on the Comtrol Rocketport driver:
2099#
2100# The exact values used for rp0 depend on how many boards you have
2101# in the system. The manufacturer's sample configs are listed as:
2102#
2103# device rp # core driver support
2104#
2105# Comtrol Rocketport ISA single card
2106# hints.rp.0.at="isa"
2107# hints.rp.0.port="0x280"
2108#
2109# If instead you have two ISA cards, one installed at 0x100 and the
2110# second installed at 0x180, then you should add the following to
2111# your kernel probe hints:
2112# hints.rp.0.at="isa"
2113# hints.rp.0.port="0x100"
2114# hints.rp.1.at="isa"
2115# hints.rp.1.port="0x180"
2116#
2117# For 4 ISA cards, it might be something like this:
2118# hints.rp.0.at="isa"
2119# hints.rp.0.port="0x180"
2120# hints.rp.1.at="isa"
2121# hints.rp.1.port="0x100"
2122# hints.rp.2.at="isa"
2123# hints.rp.2.port="0x340"
2124# hints.rp.3.at="isa"
2125# hints.rp.3.port="0x240"
2126#
2127# And for PCI cards, you need no hints.
2128
2129# Notes on the Digiboard driver:
2130#
2131# The following flag values have special meanings in dgb:
2132# 0x01 - alternate layout of pins
2133# 0x02 - use the windowed PC/Xe in 64K mode
2134
2135# Notes on the Specialix SI/XIO driver:
2136# The host card is memory, not IO mapped.
2137# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2138# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2139# The cards can use an IRQ of 11, 12 or 15.
2140
2141# Notes on the Sony Programmable I/O controller
2142# This is a temporary driver that should someday be replaced by something
2143# that hooks into the ACPI layer. The device is hooked to the PIIX4's
2144# General Device 10 decoder, which means you have to fiddle with PCI
2145# registers to map it in, even though it is otherwise treated here as
2146# an ISA device. At the moment, the driver polls, although the device
2147# is capable of generating interrupts. It largely undocumented.
2148# The port location in the hint is where you WANT the device to be
2149# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2150# is the only thing truly supported, but aparently a fair percentage
2151# of the Vaio extra features are controlled by this device.
2152
2153# Notes on the Stallion stl and stli drivers:
2154# See src/i386/isa/README.stl for complete instructions.
2155# This is version 0.0.5alpha, unsupported by Stallion.
2156# The stl driver has a secondary IO port hard coded at 0x280. You need
2157# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2158# The "flags" and "msize" settings on the stli driver depend on the board:
2159# EasyConnection 8/64 ISA: flags 23 msize 0x1000
2160# EasyConnection 8/64 EISA: flags 24 msize 0x10000

2107# Notes on the Comtrol Rocketport driver:
2108#
2109# The exact values used for rp0 depend on how many boards you have

2111#
2112# device rp # core driver support
2113#
2114# Comtrol Rocketport ISA single card
2115# hints.rp.0.at="isa"
2116# hints.rp.0.port="0x280"
2117#
2118# If instead you have two ISA cards, one installed at 0x100 and the

2123# hints.rp.1.at="isa"

2136# And for PCI cards, you need no hints.
2137
2138# Notes on the Digiboard driver:
2139#
2140# The following flag values have special meanings in dgb:
2141# 0x01 - alternate layout of pins
2142# 0x02 - use the windowed PC/Xe in 64K mode
2143
2144# Notes on the Specialix SI/XIO driver:
2145# The host card is memory, not IO mapped.
2146# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2147# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2148# The cards can use an IRQ of 11, 12 or 15.
2149
2150# Notes on the Sony Programmable I/O controller
2151# This is a temporary driver that should someday be replaced by something
2152# that hooks into the ACPI layer. The device is hooked to the PIIX4's
2153# General Device 10 decoder, which means you have to fiddle with PCI
2154# registers to map it in, even though it is otherwise treated here as
2155# an ISA device. At the moment, the driver polls, although the device
2156# is capable of generating interrupts. It largely undocumented.
2157# The port location in the hint is where you WANT the device to be
2158# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2159# is the only thing truly supported, but aparently a fair percentage
2160# of the Vaio extra features are controlled by this device.
2161

2163# See src/i386/isa/README.stl for complete instructions.
2164# This is version 0.0.5alpha, unsupported by Stallion.
2165# The stl driver has a secondary IO port hard coded at 0x280. You need
2166# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
2167# The "flags" and "msize" settings on the stli driver depend on the board:
