53# Options for CPU features.
54#
55# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
56# CPU if CPU supports it. The default is double-clock mode on
57# BlueLightning CPU box.
58#
59# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
60# BlueLightning CPU. It works only with Cyrix FPU, and this option
61# should not be used with Intel FPU.
62#
63# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
64#
65# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
66# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
67# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
68#
69# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
70# mapped mode. Default is 2-way set associative mode.
71#
72# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
73# reorder). This option should not be used if you use memory mapped
74# I/O device(s).
75#
76# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
77# machines. VmWare 3.x seems to emulate this instruction poorly, causing
78# the guest OS to run very slowly. This problem appears to be fixed in
79# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
80# VmWare 4.x will result in locking operations to be 20-30 times slower.
81# Enabling this with an SMP kernel will cause the kernel to be unusable.
82#
83# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
84#
85# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
86#
87# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
88# for i386 machines.
89#
90# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
91# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
92# (no clock delay).
93#
94# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
95# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
96# The default value is 5.
97#
98# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
99# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
100# 1).
101#
102# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
103# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
104# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
105#
106# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
107#
108# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
109# enters suspend mode following execution of HALT instruction.
110#
111# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
112#
113# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
114# K5/K6/K6-2 CPUs.
115#
116# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
117# flush at hold state.
118#
119# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
120# without cache flush at hold state, and (2) write-back CPU cache on
121# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
122#
123# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
124# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
125# executed. This option is only needed if I586_CPU is also defined,
126# and should be included for any non-Pentium CPU that defines it.
127#
128# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
129# which indicates that the 15-16MB range is *definitely* not being
130# occupied by an ISA memory hole.
131#
132# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
133# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
134# These options may crash your system.
135#
136# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
137# in write-through mode when revision < 2.7. If revision of Cyrix
138# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
