51 # Options for CPU features.
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.
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.
61 # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
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)
67 # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
68 # mapped mode. Default is 2-way set associative mode.
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
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.
81 # CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
83 # CPU_FASTER_5X86_FPU enables faster FPU exception handler.
85 # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
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
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.
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
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.
104 # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
106 # CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
107 # enters suspend mode following execution of HALT instruction.
109 # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
111 # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
114 # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
115 # flush at hold state.
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).
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.
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.
130 # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
131 # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
132 # These options may crash your system.
134 # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
135 # in write-through mode when revision < 2.7. If revision of Cyrix
136 # 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

176 # DEVICE_POLLING adds support for mixed interrupt-polling handling
177 # of network device drivers, which has significant benefits in terms
178 # of robustness to overloads and responsivity, as well as permitting
