50111314Snyan# You must specify at least one CPU (the one you intend to run on);
51111314Snyan# deleting the specification for CPUs you don't need to use may make

58111314Snyan#
59111314Snyan# Options for CPU features.
60111314Snyan#
61124795Snyan# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
62124795Snyan# CPU if CPU supports it.  The default is double-clock mode on
63124795Snyan# BlueLightning CPU box.
64124795Snyan#
65111314Snyan# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
66111314Snyan# BlueLightning CPU.  It works only with Cyrix FPU, and this option
67111314Snyan# should not be used with Intel FPU.
68111314Snyan#
69111314Snyan# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
70111314Snyan#
71111314Snyan# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
72111314Snyan# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
73111314Snyan# Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
74111314Snyan#
75124795Snyan# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
76124795Snyan# mapped mode.  Default is 2-way set associative mode.
77124795Snyan#
78127520Snyan# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
79111314Snyan# reorder).  This option should not be used if you use memory mapped
80111314Snyan# I/O device(s).
81111314Snyan#
82125234Snyan# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
83137526Snyan# machines.  VmWare 3.x seems to emulate this instruction poorly, causing
84137526Snyan# the guest OS to run very slowly.  This problem appears to be fixed in
85137526Snyan# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
86137526Snyan# VmWare 4.x will result in locking operations to be 20-30 times slower.
87137526Snyan# Enabling this with an SMP kernel will cause the kernel to be unusable.
88124795Snyan#
89127520Snyan# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
90124795Snyan#
91111314Snyan# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
92111314Snyan#
93111314Snyan# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
94111314Snyan# for i386 machines.
95111314Snyan#
96111314Snyan# CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
97111314Snyan# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
98111314Snyan# (no clock delay).
99111314Snyan#
100125234Snyan# CPU_L2_LATENCY specifies the L2 cache latency value.  This option is used
101111314Snyan# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
102111314Snyan# The default value is 5.
103111314Snyan#
104111314Snyan# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
105111314Snyan# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
106111314Snyan# 1).
107111314Snyan#
108111314Snyan# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
109111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
110111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
111111314Snyan#
112111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
113111314Snyan#
114111314Snyan# CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
115111314Snyan# enters suspend mode following execution of HALT instruction.
116111314Snyan#
117111314Snyan# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
118111314Snyan#
119111314Snyan# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
120125234Snyan# K5/K6/K6-2 CPUs.
121111314Snyan#
122111314Snyan# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
123111314Snyan# flush at hold state.
124111314Snyan#
125111314Snyan# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
126111314Snyan# without cache flush at hold state, and (2) write-back CPU cache on
127111314Snyan# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
128111314Snyan#
129111314Snyan# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
130111314Snyan# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
131111314Snyan# executed.  This option is only needed if I586_CPU is also defined,
132111314Snyan# and should be included for any non-Pentium CPU that defines it.
133111314Snyan#
134111314Snyan# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
135111314Snyan# which indicates that the 15-16MB range is *definitely* not being
136111314Snyan# occupied by an ISA memory hole.
137111314Snyan#
138111314Snyan# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
139111314Snyan# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
140111314Snyan# These options may crash your system.
141111314Snyan#
142111314Snyan# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
143111314Snyan# in write-through mode when revision < 2.7.  If revision of Cyrix
144111314Snyan# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
145111314Snyan#
146111314Snyan# NOTE 3: This option may cause failures for software that requires
147111314Snyan# locked cycles in order to operate correctly.

186111314Snyan# of robustness to overloads and responsivity, as well as permitting
187111314Snyan# accurate scheduling of the CPU time between kernel network processing
