63#
64# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
65# CPU if CPU supports it. The default is double-clock mode on
66# BlueLightning CPU box.
67#
68# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
69# BlueLightning CPU. It works only with Cyrix FPU, and this option
70# should not be used with Intel FPU.
71#
72# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
73#
74# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
75# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
76# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
77#
78# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
79# mapped mode. Default is 2-way set associative mode.
80#
81# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
82# reorder). This option should not be used if you use memory mapped
83# I/O device(s).
84#
85# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
86# machines. VmWare 3.x seems to emulate this instruction poorly, causing
87# the guest OS to run very slowly. This problem appears to be fixed in
88# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
89# VmWare 4.x will result in locking operations to be 20-30 times slower.
90# Enabling this with an SMP kernel will cause the kernel to be unusable.
91#
92# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
93#
94# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default

98#
99# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
100# for i386 machines.
101#
102# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
103# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
104# (no clock delay).
105#
106# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
107# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
108# The default value is 5.
109#
110# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
111# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
112# 1).
113#
114# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
115# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
116# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
117#
118# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
119#
120# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
121# enters suspend mode following execution of HALT instruction.
122#
123# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
124#
125# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
126# K5/K6/K6-2 CPUs.
127#
128# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
129# flush at hold state.
130#
131# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
132# without cache flush at hold state, and (2) write-back CPU cache on
133# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
134#
135# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
136# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
137# executed. This option is only needed if I586_CPU is also defined,
138# and should be included for any non-Pentium CPU that defines it.
139#
140# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
141# which indicates that the 15-16MB range is *definitely* not being

191# DEVICE_POLLING adds support for mixed interrupt-polling handling
192# of network device drivers, which has significant benefits in terms
193# of robustness to overloads and responsivity, as well as permitting
194# accurate scheduling of the CPU time between kernel network processing
195# and other activities. The drawback is a moderate (up to 1/HZ seconds)
196# potential increase in response times.
197# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
198# to achieve smoother behaviour.
199# Additionally, you can enable/disable polling at runtime with the
200# sysctl variable kern.polling.enable (defaults off), and select
201# the CPU fraction reserved to userland with the sysctl variable
202# kern.polling.user_frac (default 50, range 0..100).

196# DEVICE_POLLING adds support for mixed interrupt-polling handling
197# of network device drivers, which has significant benefits in terms
198# of robustness to overloads and responsivity, as well as permitting
199# accurate scheduling of the CPU time between kernel network processing
200# and other activities. The drawback is a moderate (up to 1/HZ seconds)
201# potential increase in response times.
202# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
203# to achieve smoother behaviour.
204# Additionally, you can enable/disable polling at runtime with the
205# sysctl variable kern.polling.enable (defaults off), and select
206# the CPU fraction reserved to userland with the sysctl variable
207# kern.polling.user_frac (default 50, range 0..100).
