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#
83# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
84#
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
128# occupied by an ISA memory hole.

331# 0x04 don't use the npx registers to optimize copyin or copyout.
332# The npx registers are normally used to optimize copying and zeroing when
333# all of the following conditions are satisfied:
334# I586_CPU is an option
335# the cpu is an i586 (perhaps not a Pentium)
336# the probe for npx0 succeeds
337# INT 16 exception handling works.
338# Then copying and zeroing using the npx registers is normally 30-100% faster.
339# The flags can be used to control cases where it doesn't work or is slower.
340# Setting them at boot time using hints works right (the optimizations
341# are not used until later in the bootstrap when npx0 is attached).
