7684b08b56 Add back "NO_MODULES" as using ``make -DMODULES_WITH_WORLD'' in the
kernel build dir doesn't really say what your intentions are.

f94a3783cf If "MODULES_WITH_WORLD" is defined, sys/modules will be built with the
world as was our old way, rather than when building a kernel.

Some people do not like the new way, and the release building still assumes
modules are built with the world.

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.

f47f0edde4 Use "nm | awk ..." instead of genassym(1) to generate symbol value headers.
Symbol values are now represented using array sizes (4 arrays per symbol
so that 16-bit machines can represent 64-bit values) instead of being raw
binary values.

10ae1068e5 Cause modules to build with the kernel build. Modules are removed
from the sys Makefile's SUBDIRs.  This is conditioned in make.conf by the
NO_MODULES variable and the existence of the modules directory.  The
actual location of the modules is not modified.  Changes in Makefiles
only, this does not affect Peter's recent changes.

f7b7769172 * Factor out the object system from new-bus so that it can be used by
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

d2b1bc7312 Put on my asbestos suit and move $mach/conf/*.$mach to conf/*.$mach as
hinted at in the previous config(8) commits.  I've spoken about this with
a few people and after the initial suprise wore off they thought it wasn't
a bad idea.  The upshot of it is that all the files*, Makefile*, options*
files are all right next to each other in the hope that people making
changes to one set will remember the others.

Note, config(8) looks to sys/conf first, and falls back to sys/$mach/conf
still, so this doesn't stop people working in subdirs for new platforms.
But once it's in the tree it can be moved next to the other files so that
the non-i386 platforms are (hopefully) treated a little better than as if
they were "second class" ports.

This does not change any user editable files.  the config program is
still run in the same directory as before, the per-platform files
(GENERIC, LINT etc) are still in the same place.

574b36f9b7 Be more consistant in using perl vs. perl5. We were using perl5 in the
kernel builds so as not to confuse with perl4 when bootstrapping from old
systems.  I don't know if this is still applicable but it shouldn't hurt
to be consistant at least.

Also copy vnode_if.sh to vnode_if.pl.  Doing a 'sh vnode_if.sh' when it
was a perl script was kinda silly.

6f77b2defc Use a seperate -c and -h mode. The vnode_if.c file is compiled only into
the kernel while the vnode_if.h header is a bunch of inlines to call the
code that is in the kernel. Generating the .h file on the fly is kinda
bogus because it has to match the one compiled into the kernel.

IMHO we should have kern/vnode_if.c and sys/vnode_if.h committed in the
tree but that's another battle.

b307e58fc7 Major lobotomy of config(8). The
config kernel mumble mumble

line has been obsoleted and removed and with it went all knowledge of
devices on the part of config.

You can still configure a root device (which is used if you give
the "-r" flag) but now with an option:

        options         ROOTDEVNAME=\"da0s2e\"

The string is parsed by the same code as at the "boot -a" prompt.

At the same time, make the "boot -a" prompt both more able and more
informative.

ALPHA/PC98 people:  You will have to adapt a few simple changes
(defining rootdev and dumpdev somewhere else) before config works
for you again, sorry, but it's all in the name of progress.

6d04a6cb97 I'm sick of the automatic rename of /kernel to /kernel.old while doing
development that leads to lots of crashes during boot.

I have made a 'reinstall' target (like in ports, and reinstall.debug)
This is most useful if you want to keep /kernel.old as a known bootable
kernel.  If you test a new kernel and have to reboot for a fix, a
'make reinstall' will install the new kernel over the top of the old
non-viable one, leaving the old one untouched.  This is mainly meant
for development, not general users.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.
