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.

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

f7b7769172 * Factor out the object system from new-bus so that it can be used by

* 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

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

to be consistant at least.

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.

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.

(defining rootdev and dumpdev somewhere else) before config works

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

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.)

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.

2907af2a96 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

43482c407d Force the order of the setdefs* so that make -jN doesn't build the
setdefs* multiple times at the same time that it's compiling setdefs[0].c.
I think this was leading to unterminated linker sets etc.

f7dd86c147 Use the gensetdefs that is now in /usr/bin, it's a superset of the
one in the kernel source, and that one is already used for modules.

I don't _think_ this will hurt releases, aout-to-elf, etc, but it is
possible.  In all the cases I've looked at, config(8) has been
generated straight after a make world, so if /usr/sbin/config exists and
is the right version for the kernel, then we can pretty much count on
/usr/bin/gensetdefs being there too.

f92bdbd010 Switch to using ".So" as the extension for PIC object files rather

3d89c2cdb2 Regrettably, you can't take setdef0.c out of order, or, surprise,
linker sets don't work and thus neither does the kernel.

This should stop being a problem with an improved linker set mechanism in
the pipeline (see the bootloader) but for now this has to stay like this.

f7c9e34bea If there is no .depends file, use the standard ad-hoc way of ensuring
that the generated files are generated before any of the object files.
Also minor cleanup of dependencies in conf/files that I bogusly added
before.

This should fix the requirement that make depend be done starting from
a clean config directory.  If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.

6b7a14ce57 Make the ELF kernel build produce a dynamic executable (!). This enables
the in-kernel linker to access the _DYNAMIC data for doing loadable elf
modules.  The alpha kernel is already done this way, I've borrowed some of
the hacks from there.

This is primarily aimed at the 3-stage boot process which is intended to
be able to do pre-loading of kernel modules.

Note that the entry point isn't 0xf0100000 any more, it'll be a little
further on - but this value is stored in the headers.  I don't think this
will be a problem, but I'm sure somebody will tell me if it is. :-)

I'm not sure if btxboot is going to like this, it doesn't do proper ELF
header checking and assumes that there are exactly two program header
entries and that they are both PT_LOAD entries - a bad assumption.

5b036e2b3c Fixed missing dependencies of genassym.o, gensetdefs.o and vers.o
on opt_global.h.  This actually matters for genassym.o (it depends
on at least SMP).

Don't undefine KERNEL for compiling genassym.c.  genassym.o really
depends on KERNEL, and the prototype mismatches that required
undefining KERNEL in rev.1.49 no longer exist.

Compile gensetdefs* with the same flags as genassym*.  External
`gen' programs such linux_genassym should also use these flags
(${GEN_CFLAGS}).

Fixed missing dependency generation for gensetdefs.o.  C sources
for external `gen' programs should be added to GEN_CFILES to get
their dependencies generated.

Cleaned up flags definitions and use.  All of ${CFLAGS} is now
passed to mkdep and the assembler (both are actually variants of
${CC} and will ignore the irrelevant flags).

Give an explicit rule for building vnode_if.o.  This fixes building
it without ${PROF}.

Use .ORDER instead of a stamp file to avoid building vnode_if.[ch]
concurrently.
