Thus, the apic device is not strictly an SMP option, 29122755Snyan# but it is a prerequisite for SMP. 30111314Snyan# 31111314Snyan# Notes: 32111314Snyan# 33122755Snyan# By default, mixed mode is used to route IRQ0 from the AT timer via 34122755Snyan# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 35122755Snyan# This can be disabled via the NO_MIXED_MODE option. In that case, 36122755Snyan# IRQ0 will be routed via an intpin on the first I/O APIC.

It works only with Cyrix FPU, and this option 75111314Snyan# should not be used with Intel FPU. 76111314Snyan# 77111314Snyan# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 78111314Snyan# 79111314Snyan# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 80111314Snyan# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 81111314Snyan# Otherwise, the NO_LOCK bit of CCR1 is cleared.

This option should not be used if you use memory mapped 88111314Snyan# I/O device(s). 89111314Snyan# 90125234Snyan# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 91137526Snyan# machines. VmWare 3.x seems to emulate this instruction poorly, causing 92137526Snyan# the guest OS to run very slowly. This problem appears to be fixed in 93137526Snyan# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 94137526Snyan# VmWare 4.x will result in locking operations to be 20-30 times slower. 95137526Snyan# Enabling this with an SMP kernel will cause the kernel to be unusable. 96124795Snyan# 97127520Snyan# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 98124795Snyan# 99111314Snyan# CPU_ENABLE_SSE enables SSE/MMX2 instructions support.

Default values of 108111314Snyan# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 109111314Snyan# (no clock delay). 110111314Snyan# 111125234Snyan# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 112111314Snyan# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 113111314Snyan# The default value is 5. 114111314Snyan# 115111314Snyan# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 116111314Snyan# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 117111314Snyan# 1). 118111314Snyan# 119111314Snyan# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 120111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 121111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 122111314Snyan# 123111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 124111314Snyan# 125111314Snyan# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 126111314Snyan# enters suspend mode following execution of HALT instruction. 127111314Snyan# 128111314Snyan# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 129111314Snyan# 130111314Snyan# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 131125234Snyan# K5/K6/K6-2 CPUs. 132111314Snyan# 133111314Snyan# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 134111314Snyan# flush at hold state. 135111314Snyan# 136111314Snyan# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 137111314Snyan# without cache flush at hold state, and (2) write-back CPU cache on 138111314Snyan# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 139111314Snyan# 140111314Snyan# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 141111314Snyan# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 142111314Snyan# executed. This option is only needed if I586_CPU is also defined, 143111314Snyan# and should be included for any non-Pentium CPU that defines it. 144111314Snyan# 145111314Snyan# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 146111314Snyan# which indicates that the 15-16MB range is *definitely* not being 147111314Snyan# occupied by an ISA memory hole. 148111314Snyan# 149111314Snyan# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 150111314Snyan# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 151111314Snyan# These options may crash your system. 152111314Snyan# 153111314Snyan# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 154111314Snyan# in write-through mode when revision < 2.7.

The PGE feature allows pages 728111314Snyan# to be marked with the PG_G bit. TLB entries for these pages are not 729111314Snyan# flushed from the cache when %cr3 is reloaded. This can make context 730111314Snyan# switches less expensive. You should only disable this feature as a 731111314Snyan# temporary workaround if you are having problems with it enabled. 732111314Snyan# 733111314Snyan#options DISABLE_PG_G 734111314Snyan 735111314Snyan# KSTACK_PAGES is the number of memory pages to assign to the kernel 736111314Snyan# stack of each thread. 737111314Snyan 738111314Snyanoptions KSTACK_PAGES=3 739111314Snyan 740111314Snyan##################################################################### 741111314Snyan 742111314Snyan# More undocumented options for linting. 743111314Snyan# Note that documenting these are not considered an affront. 744111314Snyan 745111314Snyanoptions FB_INSTALL_CDEV # install a CDEV entry in /dev 746111314Snyan 747111314Snyan# PECOFF module (Win32 Execution Format) 748111314Snyanoptions PECOFF_SUPPORT 749111314Snyanoptions PECOFF_DEBUG 750111314Snyan 751111314Snyanoptions I4B_SMP_WORKAROUND 752111314Snyanoptions I586_PMC_GUPROF=0x70000 753111314Snyanoptions KBDIO_DEBUG=2 754111314Snyanoptions KBD_MAXRETRY=4 755111314Snyanoptions KBD_MAXWAIT=6 756111314Snyanoptions KBD_RESETDELAY=201 757111314Snyan 758111314Snyanoptions TIMER_FREQ=((14318182+6)/12) 759111314Snyan 760111314Snyanoptions VM_KMEM_SIZE 761111314Snyanoptions VM_KMEM_SIZE_MAX 762111314Snyanoptions VM_KMEM_SIZE_SCALE 763111314Snyan 764111500Sobrien 765132960Snyan# The I/O device 766132960Snyandevice io 767132960Snyan 768132960Snyan 769111500Sobrien##################################################################### 770111500Sobrien# Devices we don't want to deal with 771111500Sobrien 772111500Sobriennodevice atkbdc 773111500Sobriennodevice atkbd 774111500Sobriennodevice psm 775111500Sobriennodevice vga 776116382Snyannodevice bt 777116382Snyannodevice adw 778111500Sobriennodevice aha 779116382Snyannodevice ahb 780116382Snyannodevice ahd 781116382Snyannodevice mpt 782116382Snyannodevice trm 783111500Sobriennodevice wds 784111500Sobriennodevice asr 785111500Sobriennodevice dpt 786111500Sobriennodevice ciss 787111500Sobriennodevice iir 788111500Sobriennodevice mly 789111500Sobriennodevice ida # Compaq Smart RAID 790111500Sobriennodevice mlx # Mylex DAC960 791111500Sobriennodevice amr # AMI MegaRAID 792111500Sobriennodevice twe # 3ware ATA RAID 793125086Snyannodevice ataraid 794116382Snyannodevice cm 795116382Snyannodevice cs 796116382Snyannodevice ex 797116382Snyannodevice fea 798111500Sobriennodevice cbb 799111500Sobriennodevice pccard 800111500Sobriennodevice cardbus 801116382Snyannodevice intpm 802116382Snyannodevice alpm 803116382Snyannodevice ichsmb 804116382Snyannodevice viapm 805116382Snyannodevice amdpm 806116382Snyannodevice nfpm 807111582Sru 808111582Sru 809111582Sru##################################################################### 810111582Sru# Options we don't want to deal with 811111582Sru 812111582Srunooption VGA_DEBUG 813111582Srunooption VGA_WIDTH90 814111582Srunooption VGA_SLOW_IOACCESS 815111582Srunooption VGA_ALT_SEQACCESS 816111582Srunooption PSM_RESETAFTERSUSPEND 817111582Srunooption PSM_HOOKRESUME 818111582Srunooption ATKBD_DFLT_KEYMAP 819116382Snyannooption AHD_DEBUG 820116382Snyannooption AHD_DEBUG_OPTS 821116382Snyannooption AHD_REG_PRETTY_PRINT 822116382Snyannooption ADW_ALLOW_MEMIO 823111582Srunooption DPT_LOST_IRQ 824111582Srunooption DPT_RESET_HBA 825111582Srunooption DPT_TIMEOUT_FACTOR 826116382Snyannooption AAC_DEBUG 827116382Snyannooption ACPI_MAX_THREADS 828111582Sru 829111582Sru 830111582Sru##################################################################### 831111582Sru# Make options we don't want to deal with 832111582Sru 833111582Srunomakeoption ATKBD_DFLT_KEYMAP 834
