Make TUNE_1542 a new-style option, and enable this option in LINT. It has been disabled since 1994 by mistake (or at least I hope so :-)

# $Id: options.i386,v 1.74 1998/02/20 04:19:15 steve Exp $
Create a special option file "opt_global.h" which is included by all source files via a 'cc -include opt_global.h ...' type arrangement. This means we can untangle certain header files. options.i386 has a placeholder until it has a real member so we can avoid having to teach config about it just yet. Reviewed by: bde

DISABLE_PSE
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.)

MATH_EMULATE opt_math_emulate.h
GPL_MATH_EMULATE opt_math_emulate.h
Convert the VM86 option from a global option to an option only depended on by the files that use it. Changing the VM86 option now only causes a recompile of a dozen files or so rather than the entire kernel.

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.

teach sio how to attach to isa PnP cards. This is mainly for use with internal modems. Currently detects a USR modem, and a couple Supra modems... vendor id's for sio capabile cards welcomed... document new option EXTRA_SIO that will increase sio's internal data structures to support X more serial ports... these are used by the PnP part of sio for attaching... If you don't have it specified, it will default to 2... This is defaulted to 0 if you don't have PnP compiled into your kernel... also document that if you set the PnP flags (pnp x flags y) to 0x1 that the modem will be refused to be recognized by the sio driver... this is for people that want the traditional isa driver to probe and attach the modem... (for keeping legacy sio numbering)

I586_CTR_GUPROF opt_defunct.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

Round 1 of a long series of commits.. Move SMP and APIC_IO from opt_smp.h to opt_global.h
1997-05-07 19:39:16 +00:00
# These two SMP options have dramatic implications all over the kernel
SMP opt_global.h
APIC_IO opt_global.h
# Standard SMP options
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!

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.

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
