It works only with Cyrix FPU, and this option 74# should not be used with Intel FPU. 75# 76# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 77# CPU if CPU supports it. The default is double-clock mode on 78# BlueLightning CPU box. 79# 80# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 81# 82# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 83# mapped mode. Default is 2-way set associative mode. 84# 85# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 86# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 87# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 88# 89# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 90# reorder). This option should not be used if you use memory mapped 91# I/O device(s). 92# 93# CPU_ELAN enables support for AMDs ElanSC520 CPU. 94# ELAN_XTAL sets the clock crystal frequency in Hz 95# ELAN_PPS enables precision timestamp code. 96# 97# CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default 98# on I686_CPU and above. 99# CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE. 100# 101# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 102# 103# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 104# for i386 machines. 105# 106# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 107# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 108# (no clock delay). 109# 110# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used 111# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 112# The default value is 5. 113# 114# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 115# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 116# 1). 117# 118# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 119# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 120# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 121# 122# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 123# 124# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 125# enters suspend mode following execution of HALT instruction. 126# 127# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 128# 129# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 130# K5/K6/K6-2 cpus. 131# 132# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 133# flush at hold state. 134# 135# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 136# without cache flush at hold state, and (2) write-back CPU cache on 137# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 138# 139# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 140# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 141# executed. This option is only needed if I586_CPU is also defined, 142# and should be included for any non-Pentium CPU that defines it. 143# 144# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 145# which indicates that the 15-16MB range is *definitely* not being 146# occupied by an ISA memory hole. 147# 148# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 149# machines. VmWare seems to emulate this instruction poorly, causing 150# the guest OS to run very slowly. Enabling this with a SMP kernel 151# will cause the kernel to be unusable. 152# 153# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 154# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 155# These options may crash your system. 156# 157# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 158# in write-through mode when revision < 2.7. If revision of Cyrix 159# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 160# 161# NOTE 3: This option may cause failures for software that requires 162# locked cycles in order to operate correctly. 163# 164options CPU_ATHLON_SSE_HACK 165options CPU_BLUELIGHTNING_FPU_OP_CACHE 166options CPU_BLUELIGHTNING_3X 167options CPU_BTB_EN 168options CPU_DIRECT_MAPPED_CACHE 169options CPU_DISABLE_5X86_LSSER 170options CPU_ELAN 171options ELAN_XTAL=32768000 172options ELAN_PPS 173options CPU_ENABLE_SSE 174#options CPU_DISABLE_SSE 175options CPU_FASTER_5X86_FPU 176options CPU_I486_ON_386 177options CPU_IORT 178options CPU_L2_LATENCY=5 179options CPU_LOOP_EN 180options CPU_PPRO2CELERON 181options CPU_RSTK_EN 182options CPU_SUSP_HLT 183options CPU_UPGRADE_HW_CACHE 184options CPU_WT_ALLOC 185options CYRIX_CACHE_WORKS 186options CYRIX_CACHE_REALLY_WORKS 187#options NO_F00F_HACK 188options CPU_DISABLE_CMPXCHG 189 190# 191# A math emulator is mandatory if you wish to run on hardware which 192# does not have a floating-point processor.

The PGE feature allows pages 1066# to be marked with the PG_G bit. TLB entries for these pages are not 1067# flushed from the cache when %cr3 is reloaded. This can make context 1068# switches less expensive. You should only disable this feature as a 1069# temporary workaround if you are having problems with it enabled. 1070# 1071#options DISABLE_PG_G 1072 1073# KSTACK_PAGES is the number of memory pages to assign to the kernel 1074# stack of each thread. 1075 1076options KSTACK_PAGES=3 1077 1078##################################################################### 1079 1080# More undocumented options for linting. 1081# Note that documenting these are not considered an affront. 1082 1083options FB_INSTALL_CDEV # install a CDEV entry in /dev 1084 1085# PECOFF module (Win32 Execution Format) 1086options PECOFF_SUPPORT 1087options PECOFF_DEBUG 1088 1089options ENABLE_ALART 1090options I4B_SMP_WORKAROUND 1091options I586_PMC_GUPROF=0x70000 1092options KBDIO_DEBUG=2 1093options KBD_MAXRETRY=4 1094options KBD_MAXWAIT=6 1095options KBD_RESETDELAY=201 1096 1097options PSM_DEBUG=1 1098 1099options TIMER_FREQ=((14318182+6)/12) 1100 1101options VM_KMEM_SIZE 1102options VM_KMEM_SIZE_MAX 1103options VM_KMEM_SIZE_SCALE 1104 1105# Yet more undocumented options for linting. 1106options COMPAT_SUNOS 1107
