68#
69# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
70# CPU if CPU supports it. The default is double-clock mode on
71# BlueLightning CPU box.
72#
73# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
74# BlueLightning CPU. It works only with Cyrix FPU, and this option
75# should not be used with Intel FPU.
76#
77# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
78#
79# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
80# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
81# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
82#
83# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
84# mapped mode. Default is 2-way set associative mode.
85#
86# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
87# reorder). This option should not be used if you use memory mapped
88# I/O device(s).
89#
90# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
91# machines. VmWare seems to emulate this instruction poorly, causing
92# the guest OS to run very slowly. Enabling this with an SMP kernel
93# will cause the kernel to be unusable.
94#
95# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
96#
97# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default
98# on I686_CPU and above.
99#
100# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
101#
102# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
103# for i386 machines.
104#
105# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
106# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
107# (no clock delay).
108#
109# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
110# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
111# The default value is 5.
112#
113# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
114# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
115# 1).
116#
117# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
118# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
119# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
120#
121# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
122#
123# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
124# enters suspend mode following execution of HALT instruction.
125#
126# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
127#
128# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
129# K5/K6/K6-2 CPUs.
130#
131# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
132# flush at hold state.
133#
134# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
135# without cache flush at hold state, and (2) write-back CPU cache on
136# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
137#
138# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
139# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
140# executed. This option is only needed if I586_CPU is also defined,
141# and should be included for any non-Pentium CPU that defines it.
142#
143# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
144# which indicates that the 15-16MB range is *definitely* not being

314# I586_CPU is an option
315# the cpu is an i586 (perhaps not a Pentium)
316# the probe for npx0 succeeds
317# INT 16 exception handling works.
