51# Options for CPU features.
52#
53# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
54# CPU if CPU supports it. The default is double-clock mode on
55# BlueLightning CPU box.
56#
57# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
58# BlueLightning CPU. It works only with Cyrix FPU, and this option
59# should not be used with Intel FPU.
60#
61# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
62#
63# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
64# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
65# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
66#
67# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
68# mapped mode. Default is 2-way set associative mode.
69#
70# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
71# reorder). This option should not be used if you use memory mapped
72# I/O device(s).
73#
74# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
75# machines. VmWare 3.x seems to emulate this instruction poorly, causing
76# the guest OS to run very slowly. This problem appears to be fixed in
77# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
78# VmWare 4.x will result in locking operations to be 20-30 times slower.
79# Enabling this with an SMP kernel will cause the kernel to be unusable.
80#
81# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
82#

85# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
86# for i386 machines.
87#
88# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
89# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
90# (no clock delay).
91#
92# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
93# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
94# The default value is 5.
95#
96# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
97# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
98# 1).
99#
100# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
101# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
102# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
103#
104# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
105#
106# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
107# enters suspend mode following execution of HALT instruction.
108#
109# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
110#
111# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
112# K5/K6/K6-2 CPUs.
113#
114# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
115# flush at hold state.
116#
117# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
118# without cache flush at hold state, and (2) write-back CPU cache on
119# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
120#
121# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
122# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
123# executed. This option is only needed if I586_CPU is also defined,
124# and should be included for any non-Pentium CPU that defines it.
125#
126# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
127# which indicates that the 15-16MB range is *definitely* not being

176# DEVICE_POLLING adds support for mixed interrupt-polling handling
177# of network device drivers, which has significant benefits in terms
178# of robustness to overloads and responsivity, as well as permitting
179# accurate scheduling of the CPU time between kernel network processing
180# and other activities. The drawback is a moderate (up to 1/HZ seconds)
181# potential increase in response times.
182# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
183# to achieve smoother behaviour.
184# Additionally, you can enable/disable polling at runtime with help of
185# the ifconfig(8) utility, and select the CPU fraction reserved to
186# userland with the sysctl variable kern.polling.user_frac
187# (default 50, range 0..100).

213# 0x10 enable console support for this unit. Other console flags
214# (if applicable) are ignored unless this is set. Enabling
215# console support does not make the unit the preferred console.
216# Boot with -h or set boot_serial=YES in the loader. For sio(4)
217# specifically, the 0x20 flag can also be set (see above).
218# Currently, at most one unit can have console support; the
219# first one (in config file order) with this flag set is
220# preferred. Setting this flag for sio0 gives the old behaviour.
221# 0x20 force this unit to be the console (unless there is another
222# higher priority console). This replaces the COMCONSOLE option.
223# 0x40 reserve this unit for low level console operations. Do not
224# access the device in any normal way.
225# 0x80 use this port for serial line gdb support in ddb. Also known
226# as debug port.
227# PnP `flags'
228# 0x1 disable probing of this device. Used to prevent your modem
229# from being attached as a PnP modem.

535# The svr4 ABI emulator can be statically compiled into the kernel or loaded as
536# a KLD module.
537# The STREAMS network emulation code can also be compiled statically or as a
538# module. If loaded as a module, it must be loaded before the svr4 module
539# (the /usr/sbin/svr4 script does this for you). If compiling statically,
540# the `streams' device must be configured into any kernel which also
541# specifies COMPAT_SVR4. It is possible to have a statically-configured
542# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
543# script understands that it doesn't need to load the `streams' module under
544# those circumstances.
545# Caveat: At this time, `options KTRACE' is required for the svr4 emulator
546# (whether static or dynamic).

554# VM OPTIONS

556# Disable the 4 MByte page PSE CPU feature. The PSE feature allows the
557# kernel to use 4 MByte pages to map the kernel instead of 4k pages.
558# This saves on the amount of memory needed for page tables needed to
559# map the kernel. You should only disable this feature as a temporary
560# workaround if you are having problems with it enabled.
561#
562#options DISABLE_PSE
563
564# Disable the global pages PGE CPU feature. The PGE feature allows pages
565# to be marked with the PG_G bit. TLB entries for these pages are not
566# flushed from the cache when %cr3 is reloaded. This can make context
567# switches less expensive. You should only disable this feature as a
568# temporary workaround if you are having problems with it enabled.
