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.

5e06480c9f Introduce an "include" directive. It takes one argument, a filename
to be included into this one.  This works the same way as #include
does in C; as far as the user is concerned, the included file is
inlined into the current one.

Since config(8) is no longer limited to working on one user-supplied
file, printing just a line number in an error message is not
sufficient.  The new global variable yyfile represents the file
currently being parsed, and must be printed as well.

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.

9414269597 Apply the axe to some more cruft in config(8). In particular:
- redo the "at" configuration system so that it just syntax checks
  to make sure the device you're configuring something "at" appears to
  exist.  Nuke a bunch of complexity that was responsible for creating
  "clones" of wildcard devices and some wierd stuff in a few places
  including the scbus config tables etc.
- merge "controller" and "device" - there is no difference as far as
  the kernel is concernend, it's just something there to make life
  difficult for config file writers.  "controller" is now an alias for
  "device".
- emit full scsi config into the resource tables.  We could trivially
  change cam to use that rather than it's own "special" table for wiring
  and static configuration.  ATA could use this too for static wiring.
- try and emulate some of the quirks of the old system where it made
  sense.  Some were too strange though and I'd be very suprised if they
  were features and not outright bugs.  nexus handling is still strange.
  One thing in particular is that some of the wierd entries in the
  newbus devtables is now gone as it was a quirk side effect of the
  wildcard/question-mark cloning above.

GENERIC and LINT still build etc.

output of config is exactly as before. Only when an alternate output

6d41b96fd7 Implement support for conf/options and i386/conf/options.i386
Note that this code is dormant unless the options files exist.
Also, parsing of quoted options in the config files is improved.

What this allows, is all the options in LINT to be specified to be
configured as #defines in a file rather than on the CC command line at
kernel build time.  This means that 'make depend' will catch dependencies
on actual *options*, meaning that you can run 'config' and 'make depend'
in complete safety WITHOUT removing the compile directory each time.

Unfortunately, this requires a pass over the source to get the individual
files to #include the new .h files that would be generated by config.
This has a small compile time penalty (appears up to about 2% slower)
from a "fresh" build.  Of course, you should not be needing to do complete
rebuilds very often once this was completed, so it would be an overall
win for most people.

Since this code is dormant and we've got a lot of other things happening
on the kernel tree at the moment (prototypes, devfs, static declarations
etc) I am not planning on doing any changes to activate this feature just
yet.

babb4e927f Add a new `conflicts' flag for telling when a device is in conflict with
others.  The flag can be put in descriptive locations, e.g.:

device sb0      at isa? port 0x220 irq 7 conflicts drq 1 vector sbintr
or
device psm0	at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr

But is nonetheless boolean only.  You can't turn conflict checking off for
only a given type of conflict.  I didn't deem it worth the trouble at this
stage, and it's far better than the ALLOW_CONFLICT_* that preceeded it.

528486881b Allow config to fully handle the aic7770 driver dependancies. 1994-12-31 19:23:10 +00:00
Justin T. Gibbs
80785c507b Add new keywords to config. The options availible in file.i386 are now:
/*
         * filename     [ standard | optional ] [ config-dependent ]
         *      [ dev* | profiling-routine ] [ device-driver] [ no-obj ]
         *      [ compile-with "compile rule" [no-implicit-rule] ]
         *                     [ dependancy "dependancy-list"]
         */

I added

no-obj -  This entry does not create anything linkable to the kernel.
dependancy - Add additional dependancy rules to a target.
no-implicit-rule - Don't assume .c -> .o type rules.  Config is really
             dumb in this area and assumes that everything is a .c file
	     irregarless of extention.  This was the best choice really
	     since there may even be .c file that you don't want to follow
	     the standard rules.

This was all done so that the building to the aic7770 assembler and using
the aic7770 assembler in the building of the aic7770 driver could be config
dependant.  I can now have an entry like this for the driver:

aic7770                         optional        ahc     device-driver   \
        compile-with    "${CC} $> -o $@"                                \
        dependancy      "$S/gnu/misc/aic7770/aic7770.c"                 \
        no-obj no-implicit-rule
aic7770_seq.h                   optional        ahc     device-driver          \
        compile-with "${.CURDIR}/aic7770 -o $@ $S/gnu/misc/aic7770/aic7770.seq"\
        dependancy "$S/gnu/misc/aic7770/aic7770.seq aic7770"                   \
        no-obj no-implicit-rule
i386/isa/aic7770.c              optional        ahc     device-driver   \
        dependancy "aic7770_seq.h"

I also added '\' escaping to newlines so that this doesn't look as gross as
it could have.
