It works only with Cyrix FPU, and this option 67111314Snyan# should not be used with Intel FPU. 68111314Snyan# 69111314Snyan# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 70111314Snyan# 71111314Snyan# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 72111314Snyan# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 73111314Snyan# Otherwise, the NO_LOCK bit of CCR1 is cleared.

This problem appears to be fixed in 85137526Snyan# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 86137526Snyan# VmWare 4.x will result in locking operations to be 20-30 times slower. 87137526Snyan# Enabling this with an SMP kernel will cause the kernel to be unusable. 88124795Snyan# 89127520Snyan# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 90124795Snyan# 91111314Snyan# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 92111314Snyan# 93111314Snyan# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 94111314Snyan# for i386 machines. 95111314Snyan# 96111314Snyan# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 97111314Snyan# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 98111314Snyan# (no clock delay). 99111314Snyan# 100125234Snyan# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 101111314Snyan# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 102111314Snyan# The default value is 5. 103111314Snyan# 104111314Snyan# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 105111314Snyan# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 106111314Snyan# 1). 107111314Snyan# 108111314Snyan# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 109111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 110111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 111111314Snyan# 112111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 113111314Snyan# 114111314Snyan# CPU_SUSP_HLT enables suspend on HALT.

The PGE feature allows pages 701111314Snyan# to be marked with the PG_G bit. TLB entries for these pages are not 702111314Snyan# flushed from the cache when %cr3 is reloaded. This can make context 703111314Snyan# switches less expensive. You should only disable this feature as a 704111314Snyan# temporary workaround if you are having problems with it enabled. 705111314Snyan# 706111314Snyan#options DISABLE_PG_G 707111314Snyan 708111314Snyan# KSTACK_PAGES is the number of memory pages to assign to the kernel 709111314Snyan# stack of each thread. 710111314Snyan 711111314Snyanoptions KSTACK_PAGES=3 712111314Snyan 713111314Snyan##################################################################### 714111314Snyan 715111314Snyan# More undocumented options for linting. 716111314Snyan# Note that documenting these are not considered an affront. 717111314Snyan 718111314Snyanoptions FB_INSTALL_CDEV # install a CDEV entry in /dev 719111314Snyan 720111314Snyan# PECOFF module (Win32 Execution Format) 721111314Snyanoptions PECOFF_SUPPORT 722111314Snyanoptions PECOFF_DEBUG 723111314Snyan 724111314Snyanoptions I4B_SMP_WORKAROUND 725111314Snyanoptions I586_PMC_GUPROF=0x70000 726111314Snyanoptions KBDIO_DEBUG=2 727111314Snyanoptions KBD_MAXRETRY=4 728111314Snyanoptions KBD_MAXWAIT=6 729111314Snyanoptions KBD_RESETDELAY=201 730111314Snyan 731111314Snyanoptions TIMER_FREQ=((14318182+6)/12) 732111314Snyan 733111314Snyanoptions VM_KMEM_SIZE 734111314Snyanoptions VM_KMEM_SIZE_MAX 735111314Snyanoptions VM_KMEM_SIZE_SCALE 736111314Snyan 737111500Sobrien 738132960Snyan# The I/O device 739132960Snyandevice io 740132960Snyan 741132960Snyan 742111500Sobrien##################################################################### 743111500Sobrien# Devices we don't want to deal with 744111500Sobrien 745111500Sobriennodevice atkbdc 746111500Sobriennodevice atkbd 747111500Sobriennodevice psm 748111500Sobriennodevice vga 749116382Snyannodevice bt 750116382Snyannodevice adw 751111500Sobriennodevice aha 752116382Snyannodevice ahb 753116382Snyannodevice ahd 754116382Snyannodevice mpt 755116382Snyannodevice trm 756111500Sobriennodevice wds 757111500Sobriennodevice asr 758111500Sobriennodevice dpt 759111500Sobriennodevice ciss 760111500Sobriennodevice iir 761111500Sobriennodevice mly 762111500Sobriennodevice ida # Compaq Smart RAID 763111500Sobriennodevice mlx # Mylex DAC960 764111500Sobriennodevice amr # AMI MegaRAID 765111500Sobriennodevice twe # 3ware ATA RAID 766125086Snyannodevice ataraid 767116382Snyannodevice cm 768116382Snyannodevice cs 769116382Snyannodevice ex 770116382Snyannodevice fea 771111500Sobriennodevice cbb 772111500Sobriennodevice pccard 773111500Sobriennodevice cardbus 774116382Snyannodevice intpm 775116382Snyannodevice alpm 776116382Snyannodevice ichsmb 777116382Snyannodevice viapm 778116382Snyannodevice amdpm 779116382Snyannodevice nfpm 780111582Sru 781111582Sru 782111582Sru##################################################################### 783111582Sru# Options we don't want to deal with 784111582Sru 785111582Srunooption VGA_DEBUG 786111582Srunooption VGA_WIDTH90 787111582Srunooption VGA_SLOW_IOACCESS 788111582Srunooption VGA_ALT_SEQACCESS 789111582Srunooption PSM_RESETAFTERSUSPEND 790111582Srunooption PSM_HOOKRESUME 791111582Srunooption ATKBD_DFLT_KEYMAP 792116382Snyannooption AHD_DEBUG 793116382Snyannooption AHD_DEBUG_OPTS 794116382Snyannooption AHD_REG_PRETTY_PRINT 795116382Snyannooption ADW_ALLOW_MEMIO 796111582Srunooption DPT_LOST_IRQ 797111582Srunooption DPT_RESET_HBA 798111582Srunooption DPT_TIMEOUT_FACTOR 799116382Snyannooption AAC_DEBUG 800116382Snyannooption ACPI_MAX_THREADS 801111582Sru 802111582Sru 803111582Sru##################################################################### 804111582Sru# Make options we don't want to deal with 805111582Sru 806111582Srunomakeoption ATKBD_DFLT_KEYMAP 807
