Man the liferafts! Here comes the long awaited SMP -> -current merge! There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code!

# $Id: options.i386,v 1.39 1997/04/05 13:21:08 bde Exp $
Convert BOUNCE_BUFFERS and BOUNCEPAGES to new option scheme.
1996-01-05 20:12:53 +00:00
BOUNCEPAGES opt_bounce.h
Converted two options over to the new scheme: USER_LDT and KTRACE.
1996-01-03 21:42:35 +00:00
USER_LDT
Choose a different name to hold the option definition.. The original one was overlapping with another file, and making some undesirable behavior a little worse - it's triggering a bug in config that appears to have been there for some time (before the options files, anyway.)
1996-01-06 23:10:57 +00:00
MATH_EMULATE opt_math_emulate.h
GPL_MATH_EMULATE opt_math_emulate.h
Hide options for emulators and static file systems in opt_dontuse.h. These options only apply at config time. Using them at compile time would break the corresponding lkms.
1996-05-11 04:39:53 +00:00
IBCS2 opt_dontuse.h
COMPAT_LINUX opt_dontuse.h
Add more options into the conf/options and i386/conf/options.i386 files and the #include hooks so that 'make depend' is more useful. This covers most of the options I regularly use (but not all) and some other easy ones.
1996-03-02 18:24:13 +00:00
SHOW_BUSYBUFS opt_machdep.h
PANIC_REBOOT_WAIT_TIME opt_machdep.h
MAXMEM opt_machdep.h
Add support for Pentium and Pentium Pro performance counters. (This code is as yet untested; to come after man page is written.) This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC instructions. The user-mode interface is via a subdevice of mem.c; there is also a kernel-size interface which might be used to aid profiling.
1996-03-26 19:57:56 +00:00
PERFMON opt_perfmon.h
Moved AUTO_EOI_[12] and most sio and pcvt options out of the makefile.
1996-04-11 21:18:49 +00:00
AUTO_EOI_1 opt_auto_eoi.h
AUTO_EOI_2 opt_auto_eoi.h
BREAK_TO_DEBUGGER opt_comconsole.h
Moved COMCONSOLE, CONADDR and CONUNIT to defunct options.
1997-04-05 13:21:08 +00:00
COMCONSOLE opt_defunct.h
CONADDR opt_defunct.h
CONUNIT opt_defunct.h
add in CONSPEED option
1996-11-02 02:25:22 +00:00
CONSPEED opt_comconsole.h
Moved AUTO_EOI_[12] and most sio and pcvt options out of the makefile.
1996-04-11 21:18:49 +00:00
COM_ESP opt_sio.h
COM_MULTIPORT opt_sio.h
DSI_SOFT_MODEM opt_sio.h
Improved non-statistical (GUPROF) profiling: - use a more accurate and more efficient method of compensating for overheads. The old method counted too much time against leaf functions. - normally use the Pentium timestamp counter if available. On Pentiums, the times are now accurate to within a couple of cpu clock cycles per function call in the (unlikely) event that there are no cache misses in or caused by the profiling code. - optionally use an arbitrary Pentium event counter if available. - optionally regress to using the i8254 counter. - scaled the i8254 counter by a factor of 128. Now the i8254 counters overflow slightly faster than the TSC counters for a 150MHz Pentium :-) (after about 16 seconds). This is to avoid fractional overheads. files.i386: permon.c temporarily has to be classified as a profiling-routine because a couple of functions in it may be called from profiling code. options.i386: - I586_CTR_GUPROF is currently unused (oops). - I586_PMC_GUPROF should be something like 0x70000 to enable (but not use unless prof_machdep.c is changed) support for Pentium event counters. 7 is a control mode and the counter number 0 is somewhere in the 0000 bits (see perfmon.h for the encoding). profile.h: - added declarations. - cleaned up separation of user mode declarations. prof_machdep.c: Mostly clock-select changes. The default clock can be changed by editing kmem. There should be a sysctl for this. subr_prof.c: - added copyright. - calibrate overheads for the new method. - documented new method. - fixed races and and machine dependencies in start/stop code. mcount.c: Use the new overhead compensation method. gmon.h: - changed GPROF4 counter type from unsigned to int. Oops, this should be machine-dependent and/or int32_t. - reorganized overhead counters. Submitted by: Pentium event counter changes mostly by wollman

I586_CTR_GUPROF opt_i586_guprof.h

FAT_CURSOR opt_pcvt.h
Fixed `PCVT_FREEBSD=210'.

AHC_TAGENABLE opt_aic7xxx.h
AHC_SCBPAGING_ENABLE opt_aic7xxx.h
Since there have been so many reports of the Memory Mapped I/O to the aic7xxx cards failing on certain motherboards, reverse the logic used to control this feature. AHC_FORCE_PIO is replaced with AHC_ALLOW_MEMIO. GENERIC no longer needs to specify the AHC_FORCE_PIO option since this is the default.
1996-11-16 01:09:20 +00:00
AHC_ALLOW_MEMIO opt_aic7xxx.h
Add two new aic7xxx driver options: AHC_FORCE_PIO - This forces the driver to use PIO even on systems that say they have memory mapped the controller's registers. This seems to fix Ken Lam's problems. I've also placed this option in the GENERIC kernel file so that we are guaranteed to install even on these flakey machines. AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on the 398X controllers allowing a totoll of 255 non-paged SCBs. This doesn't work quite yet, so this option is mostly here to help 398X owners to experiment and give me feedback until this works properly.

Improved CPU identification and initialization routines. This supports All Cyrix CPUs, IBM Blue Lightning CPU and NexGen (now AMD) Nx586 CPU, and initialize special registers of Cyrix CPU and msr of IBM Blue Lightning CPU. If revision of Cyrix 6x86 CPU < 2.7, CPU cache is enabled in write-through mode. This can be disabled by kernel configuration options. Reviewed by: Bruce Evans <bde@freebsd.org> and Jordan K.

add SC_SPLASH_SCREEN to opt_syscons.h (sigh)

SC_SPLASH_SCREEN opt_syscons.h
Fixed spelling of new SC_KBD_PROBE_WORKS option in options.i386. It worked because it is spelled correctly in LINT. Added old obscure syscons options MAXCONS, SLOW_VGA and XT_KEYBOARD. This file should be sorted both alphabetically and on the module name by using a consistent prefix for each module, but there is no consistency in the old options. E.g., MAXCONS is spelled PCVT_NSCREENS for pcvt.

USERCONFIG opt_userconfig.h
VISUAL_USERCONFIG opt_userconfig.h
Multiple changes stacked as one commit since they all depend on one another. First, change sysinstall and the Makefile rules to not build the kernel nlist directly into sysinstall now. Instead, spit it out as an ascii file in /stand and parse it from sysinstall later. This solves the chicken-n- egg problem of building sysinstall into the fsimage before BOOTMFS is built and can have its symbols extracted. Now we generate the symbol file in release.8. Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two effects: 1. Userconfig is always entered, rather than only after a -c (don't scream yet, it's not as bad as it sounds). 2. Userconfig reads a message string which can optionally be written just past the boot blocks. This string "preloads" the userconfig input buffer and is parsed as user input. If the first command is not "USERCONFIG", userconfig will treat this as an implied "quit" (which is why you don't need to scream - you never even know you went through userconfig and back out again if you don't specifically ask for it), otherwise it will read and execute the following commands until a "quit" is seen or the end is reached, in which case the normal userconfig command prompt will then be presented. How to create your own startup sequences, using any boot.flp image from the next snap forward (not yet, but soon): % dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO USERCONFIG irq ed0 10 iomem ed0 0xcc000 disable ed1 quit WAKKA_WAKKA_DOO Third, add an intro screen to UserConfig so that users aren't just thrown into this strange screen if userconfig is auto-launched. The default boot.flp startup sequence is now, in fact, this: USERCONFIG intro visual (Since visual never returns, we don't need a following "quit"). Submitted-By: phk & jkh

USERCONFIG_BOOT opt_userconfig.h
