The default is double-clock mode on 57124795Snyan# BlueLightning CPU box. 58124795Snyan# 59111314Snyan# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 60111314Snyan# BlueLightning CPU. It works only with Cyrix FPU, and this option 61111314Snyan# should not be used with Intel FPU. 62111314Snyan# 63111314Snyan# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 64111314Snyan# 65111314Snyan# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 66111314Snyan# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 67111314Snyan# Otherwise, the NO_LOCK bit of CCR1 is cleared.

Default is 2-way set associative mode. 71124795Snyan# 72127520Snyan# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables 73111314Snyan# reorder). This option should not be used if you use memory mapped 74111314Snyan# I/O device(s). 75111314Snyan# 76125234Snyan# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 77137526Snyan# machines. VmWare 3.x seems to emulate this instruction poorly, causing 78137526Snyan# the guest OS to run very slowly. This problem appears to be fixed in 79137526Snyan# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 80137526Snyan# VmWare 4.x will result in locking operations to be 20-30 times slower. 81137526Snyan# Enabling this with an SMP kernel will cause the kernel to be unusable. 82124795Snyan# 83127520Snyan# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 84124795Snyan# 85111314Snyan# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 86111314Snyan# 87111314Snyan# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 88111314Snyan# for i386 machines. 89111314Snyan# 90111314Snyan# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 91111314Snyan# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 92111314Snyan# (no clock delay). 93111314Snyan# 94125234Snyan# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 95111314Snyan# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 96111314Snyan# The default value is 5. 97111314Snyan# 98111314Snyan# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 99111314Snyan# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 100111314Snyan# 1). 101111314Snyan# 102111314Snyan# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 103111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 104111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 105111314Snyan# 106111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 107111314Snyan# 108111314Snyan# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 109111314Snyan# enters suspend mode following execution of HALT instruction. 110111314Snyan# 111111314Snyan# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 112111314Snyan# 113111314Snyan# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 114125234Snyan# K5/K6/K6-2 CPUs. 115111314Snyan# 116111314Snyan# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 117111314Snyan# flush at hold state. 118111314Snyan# 119111314Snyan# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 120111314Snyan# without cache flush at hold state, and (2) write-back CPU cache on 121111314Snyan# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 122111314Snyan# 123111314Snyan# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 124111314Snyan# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 125111314Snyan# executed. This option is only needed if I586_CPU is also defined, 126111314Snyan# and should be included for any non-Pentium CPU that defines it. 127111314Snyan# 128111314Snyan# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 129111314Snyan# which indicates that the 15-16MB range is *definitely* not being 130111314Snyan# occupied by an ISA memory hole. 131111314Snyan# 132111314Snyan# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 133111314Snyan# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 134111314Snyan# These options may crash your system. 135111314Snyan# 136111314Snyan# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 137111314Snyan# in write-through mode when revision < 2.7.

The PGE feature allows pages 681111314Snyan# to be marked with the PG_G bit. TLB entries for these pages are not 682111314Snyan# flushed from the cache when %cr3 is reloaded. This can make context 683111314Snyan# switches less expensive. You should only disable this feature as a 684111314Snyan# temporary workaround if you are having problems with it enabled. 685111314Snyan# 686111314Snyan#options DISABLE_PG_G 687111314Snyan 688111314Snyan# KSTACK_PAGES is the number of memory pages to assign to the kernel 689111314Snyan# stack of each thread. 690111314Snyan 691111314Snyanoptions KSTACK_PAGES=3 692111314Snyan 693111314Snyan##################################################################### 694111314Snyan 695111314Snyan# More undocumented options for linting. 696111314Snyan# Note that documenting these are not considered an affront. 697111314Snyan 698111314Snyanoptions FB_INSTALL_CDEV # install a CDEV entry in /dev 699111314Snyan 700111314Snyan# PECOFF module (Win32 Execution Format) 701111314Snyanoptions PECOFF_SUPPORT 702111314Snyanoptions PECOFF_DEBUG 703111314Snyan 704111314Snyanoptions I4B_SMP_WORKAROUND 705111314Snyanoptions I586_PMC_GUPROF=0x70000 706111314Snyanoptions KBDIO_DEBUG=2 707111314Snyanoptions KBD_MAXRETRY=4 708111314Snyanoptions KBD_MAXWAIT=6 709111314Snyanoptions KBD_RESETDELAY=201 710111314Snyan 711111314Snyanoptions TIMER_FREQ=((14318182+6)/12) 712111314Snyan 713111314Snyanoptions VM_KMEM_SIZE 714111314Snyanoptions VM_KMEM_SIZE_MAX 715111314Snyanoptions VM_KMEM_SIZE_SCALE 716111314Snyan 717111500Sobrien 718132960Snyan# The I/O device 719132960Snyandevice io 720132960Snyan 721132960Snyan 722111500Sobrien##################################################################### 723111500Sobrien# Devices we don't want to deal with 724111500Sobrien 725111500Sobriennodevice atkbdc 726111500Sobriennodevice atkbd 727111500Sobriennodevice psm 728111500Sobriennodevice vga 729116382Snyannodevice bt 730116382Snyannodevice adw 731111500Sobriennodevice aha 732116382Snyannodevice ahb 733116382Snyannodevice ahd 734116382Snyannodevice mpt 735116382Snyannodevice trm 736111500Sobriennodevice wds 737111500Sobriennodevice asr 738111500Sobriennodevice dpt 739111500Sobriennodevice ciss 740111500Sobriennodevice iir 741111500Sobriennodevice mly 742111500Sobriennodevice ida # Compaq Smart RAID 743111500Sobriennodevice mlx # Mylex DAC960 744111500Sobriennodevice amr # AMI MegaRAID 745111500Sobriennodevice twe # 3ware ATA RAID 746125086Snyannodevice ataraid 747116382Snyannodevice cm 748116382Snyannodevice cs 749116382Snyannodevice ex 750116382Snyannodevice fea 751116382Snyannodevice intpm 752116382Snyannodevice alpm 753116382Snyannodevice ichsmb 754116382Snyannodevice viapm 755116382Snyannodevice amdpm 756116382Snyannodevice nfpm 757111582Sru 758111582Sru 759111582Sru##################################################################### 760111582Sru# Options we don't want to deal with 761111582Sru 762111582Srunooption VGA_DEBUG 763111582Srunooption VGA_WIDTH90 764111582Srunooption VGA_SLOW_IOACCESS 765111582Srunooption VGA_ALT_SEQACCESS 766111582Srunooption PSM_RESETAFTERSUSPEND 767111582Srunooption PSM_HOOKRESUME 768111582Srunooption ATKBD_DFLT_KEYMAP 769116382Snyannooption AHD_DEBUG 770116382Snyannooption AHD_DEBUG_OPTS 771116382Snyannooption AHD_REG_PRETTY_PRINT 772116382Snyannooption ADW_ALLOW_MEMIO 773111582Srunooption DPT_LOST_IRQ 774111582Srunooption DPT_RESET_HBA 775111582Srunooption DPT_TIMEOUT_FACTOR 776116382Snyannooption AAC_DEBUG 777116382Snyannooption ACPI_MAX_THREADS 778111582Sru 779111582Sru 780111582Sru##################################################################### 781111582Sru# Make options we don't want to deal with 782111582Sru 783111582Srunomakeoption ATKBD_DFLT_KEYMAP 784
