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. (NOTE 3) 68111314Snyan# 69124795Snyan# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 70124795Snyan# mapped mode. 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 687111314Snyan# to be marked with the PG_G bit. TLB entries for these pages are not 688111314Snyan# flushed from the cache when %cr3 is reloaded. This can make context 689111314Snyan# switches less expensive. You should only disable this feature as a 690111314Snyan# temporary workaround if you are having problems with it enabled. 691111314Snyan# 692111314Snyan#options DISABLE_PG_G 693111314Snyan 694111314Snyan# KSTACK_PAGES is the number of memory pages to assign to the kernel 695111314Snyan# stack of each thread. 696111314Snyan 697111314Snyanoptions KSTACK_PAGES=3 698111314Snyan 699111314Snyan##################################################################### 700111314Snyan 701111314Snyan# More undocumented options for linting. 702111314Snyan# Note that documenting these are not considered an affront. 703111314Snyan 704111314Snyanoptions FB_INSTALL_CDEV # install a CDEV entry in /dev 705111314Snyan 706111314Snyan# PECOFF module (Win32 Execution Format) 707111314Snyanoptions PECOFF_SUPPORT 708111314Snyanoptions PECOFF_DEBUG 709111314Snyan 710111314Snyanoptions I4B_SMP_WORKAROUND 711111314Snyanoptions I586_PMC_GUPROF=0x70000 712111314Snyanoptions KBDIO_DEBUG=2 713111314Snyanoptions KBD_MAXRETRY=4 714111314Snyanoptions KBD_MAXWAIT=6 715111314Snyanoptions KBD_RESETDELAY=201 716111314Snyan 717111314Snyanoptions TIMER_FREQ=((14318182+6)/12) 718111314Snyan 719111314Snyanoptions VM_KMEM_SIZE 720111314Snyanoptions VM_KMEM_SIZE_MAX 721111314Snyanoptions VM_KMEM_SIZE_SCALE 722111314Snyan 723111500Sobrien 724132960Snyan# The I/O device 725132960Snyandevice io 726132960Snyan 727132960Snyan 728111500Sobrien##################################################################### 729111500Sobrien# Devices we don't want to deal with 730111500Sobrien 731111500Sobriennodevice atkbdc 732111500Sobriennodevice atkbd 733111500Sobriennodevice psm 734111500Sobriennodevice vga 735116382Snyannodevice bt 736116382Snyannodevice adw 737111500Sobriennodevice aha 738116382Snyannodevice ahb 739116382Snyannodevice ahd 740116382Snyannodevice mpt 741116382Snyannodevice trm 742111500Sobriennodevice wds 743111500Sobriennodevice asr 744111500Sobriennodevice dpt 745111500Sobriennodevice ciss 746111500Sobriennodevice iir 747111500Sobriennodevice mly 748111500Sobriennodevice ida # Compaq Smart RAID 749111500Sobriennodevice mlx # Mylex DAC960 750111500Sobriennodevice amr # AMI MegaRAID 751111500Sobriennodevice twe # 3ware ATA RAID 752125086Snyannodevice ataraid 753116382Snyannodevice cm 754116382Snyannodevice ex 755116382Snyannodevice fea 756116382Snyannodevice intpm 757116382Snyannodevice alpm 758116382Snyannodevice ichsmb 759116382Snyannodevice viapm 760116382Snyannodevice amdpm 761153643Snyannodevice amdsmb 762116382Snyannodevice nfpm 763153643Snyannodevice nfsmb 764111582Sru 765111582Sru 766111582Sru##################################################################### 767111582Sru# Options we don't want to deal with 768111582Sru 769111582Srunooption VGA_DEBUG 770111582Srunooption VGA_WIDTH90 771111582Srunooption VGA_SLOW_IOACCESS 772111582Srunooption VGA_ALT_SEQACCESS 773111582Srunooption PSM_RESETAFTERSUSPEND 774111582Srunooption PSM_HOOKRESUME 775111582Srunooption ATKBD_DFLT_KEYMAP 776116382Snyannooption AHD_DEBUG 777116382Snyannooption AHD_DEBUG_OPTS 778116382Snyannooption AHD_REG_PRETTY_PRINT 779116382Snyannooption ADW_ALLOW_MEMIO 780111582Srunooption DPT_LOST_IRQ 781111582Srunooption DPT_RESET_HBA 782111582Srunooption DPT_TIMEOUT_FACTOR 783116382Snyannooption AAC_DEBUG 784116382Snyannooption ACPI_MAX_THREADS 785111582Sru 786111582Sru 787111582Sru##################################################################### 788111582Sru# Make options we don't want to deal with 789111582Sru 790111582Srunomakeoption ATKBD_DFLT_KEYMAP 791
