8365569883 Moved the setting of all profiling-related variables except the key one
(PROFLEVEL) to kern.pre.mk so that it is easier to manage.  Bumped config
version to match.

Moved the check for cputype being configured to a less bogus place in
mkmakefile.c.

7a2eb19dbf Commit some infrastructure for turning on -Werror for kernel compiles.
It doesn't actually do it yet though.  This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on.  make -DNO_WERROR would also bypass all of it.

10ca19cf93 Implement option strings that we can use in #ifdefs (where unavoidable)
as a replacement for the evil #define NFOO.  If 'device npx' is in the
static kernel, a synthetic option '#define DEV_NPX 1' will be available
to stick in an opt_xxx.h file.  "#if NNPX > 0" can be replaced with
"#ifdef DEV_NPX" and we can get rid of the overloaded meaning of the
device count mechanism.

596feda554 If a ${KERNEL}.hints file exists, and no hints are specified explicitly,
then include the hints with a marker indicating that it is a fallback.

f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

3f664fc689 A checkpoint of a part of a work-in-progress. Some more cleanups for
config(8).  This commit allows control of the creation of the
#include "foo.h" files.  We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices.  eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.

58fa7951a2 Bump configversion. The controller/device changes are upwards but not
downwards compatable.  If you try and config a s/controller/device/ kernel
with an old config(8), the results will be less than satisfactory.

e05da2e941 Made booting with -a work for all configurations. Previously it
only worked for configurations with "swap on generic".

usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
  warning about them.  They haven't done anything related to swap
  for almost 4 years, and were previously silently ignored,
  except for "swap on generic" which stopped swap${KERNEL}.c
  from being generated.  Code to support swapping is now deader
  than before.

usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.

sys/i386/conf/files.i386:
- swapgeneric.c is now standard.  It should be merged into autoconf.c
  so that it doesn't conflict with swap${KERNEL}.c for kernels named
  "generic".

sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots.  Since setroot() doesn't do anything
  harmful, this was just a waste of time, except possibly for booting with
  -a it may have helped prevent an undesireable call to setconf() by
  finding a bogus rootdev.
- honor -a for ffs roots.  -a now overrides all other ways of specifying
  the root device.  Previously, -r had precedence over -a, and the -a
  handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
  the way of a clean panic.

sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
  Don't decide things that are now decided in autoconf.c.  Code to
  support the "generic" case is now dead instead of useless.

b282e6c130 Clean up the -g/DEBUG handling. This logic can go in the Makefile
so that config -g can work the same as:  makeoptions DEBUG="-g"

84676b86e6 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same
    name).

4.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
    work if a kernel name other than 'kernel' is specified.  This is
    not absolutely necessary, but useful, and it was relatively easy.
    I now have a kernel called /crapshit :-)

5.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
    to remove both the debug and normal kernel.

6.  Modify all to install the stripped kernel by default and the debug
    kernel if you enter "make install.debug".

7.  Update version number of Makefiles and config.

4af4007dbb Ignore `vector xxxintr' specifications except for checking their syntax.
Interrupt handlers are now configured in drivers.

Didn't update config/SMM.doc.  It doesn't have any i386 examples (not
even `isa').

Bumped CONFIGVERS.  This is not necessary for -current yet, but using
the new config with old system sources gives null pointers for all
vectors.

2f8aad8b31 Bump config version. Also mention that even after rebuilding a new

or name changes documented in GENERIC or LINT.

784c3c3465 Removed all traces of PARAM in Makefile.i386. Incremented CONFIGVERS
to reflect the dependency of Makefile.i386 on nothing being put in
PARAM.

Config versioning is too closely coupled with the Makefile.i386.

afafca8bcb Don't generate declarations for isa device structs in "ioconf.h".
Don't generate declarations for isa interrupt handlers at all.
Isa interrupt handlers are now declared in <i386/isa/isa_device.h>
but should be converted take a `void *' arg and staticized as
soon as possible.

Updated CONFIGVERS.  New configs are very incompatible with
previous versions.

463fb43b0a Recognize a %VERSREQ=nnnnn string in the system Makefile. Both config(8)
and the kernel will have a 'config interface version number'.  If an
incompatable change is made to the kernel that requires a rebuild of
config(8) (such as the cam devtab stuff), then the version number would be
bumped in both places.  If a user neglects to rebuild config, then they
will get a nagging (but non-fatal) warning that they need to rebuild
config.
