config: Add no-ctfconvert support.

Bump CONFIGVERS to 600018 for this support.

Some files may purposely have debug info disabled or are *source files*
that attempt to run ctfconvert on them. Currently ctfconvert ignores
these errors but I have a change to make the errors real so we can
catch real problems like exceeding type limits.

Bump CONFIGVERS to 600017.

This change reflects the ability to change machine_arch in a config file. This

in the second one.

config(8): Add compatibility shims for r335998

Plumb the %VERSREQ from Makefile.<arch> through to the rest of config(8).
We've recorded the config(8) version that we're calling "the end of
envmode and hintmode," and we'll write them out for earlier versions. Later
kernel version bumps will remove envmode/hintmode from the kernel as needed,
which is OK since the current kernel does not use them at all.

These compatibility shims really need to go away when the major version
rolls over...

config(8): Bump major version after r335998

config-generated hints.c/env.c from r335998 and later are incompatible with
earlier kernels due to no longer setting envmode/hintmode. A minor bump for
this is insufficient, as matching major version with a later minor version
is still viewed as backwards-compatible.

This was an MI kernel change, soo all VERSREQ's are bumped.

Fix 'local' to not look in the source tree for the file.

Usually 'local' is used along with other rules such as 'no-implicit-rule' or
'dependency' which avoids this problem. It's possible to need to use 'local'
while relying on the default rules though for a file which is not in the source
tree nor generated in the kernel.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Given the lag between introducing the options-compat and fixing the
bug in the config file was long, and merged to stable, we have to bump
the version here so that stable/8 kernels can have their required
version number bumped to make sure the right config is used.

Enhance config to handle MACHINEs with multiple architectures:

- Passing -m to config will now print the MACHINE and MACHINE_ARCH
given in the passed kernel configuration file and then exit.
- If an option is defined in options.MACHINE with the same name as the
architecture of the kernel being configured, that option will be
considered set. This allows conditional compilation based on CPU
architecture.

Config version is now 600010.

600004 is a better new version than 700000 based on some future commits to

had to bump the version because the old parser would choke on | in the new

Minor comment tweak to prevent gcc from being upset about the substring

Add some rationale about when to bump and not bump the config version.
Clarify that it is not like the shlib versions, and not like param.h's

When config(8) was actively changing a while back, the interface between
config and the build system (eg: /sys/conf/files.* and Makefile.*) was
changing rapidly. configvers is a version number of that interface.

User specified config files do not have a version number. The decision
about whether a user supplied config file is syntactically valid or not
belongs to the parser and sanity checks, not an arbitary number.

since nocpu isn't used in the kernel config base, we don't need to
bump the version. Peter Wemm, John Baldwin and I hammered this out
after the last time I needlessly incremented the version.

Implement the "nocpu" directive.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed

device snd_maestro
device "snd_maestro3"
device snd_mss

I believe everything will still compile and work after this.

Add a new "files" directive, which allows to include a files.foo file directly

Bump the config version to force people to upgrade their config(8)

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

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

Bump configvers for different handling of maxusers.

Enable hardwiring of things like tunables from embedded enironments

Bump config version in config.

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.

Make the xxxFILES= list generation generic. This makes it easier to add

The kernel side of this is to come shortly.

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!

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.

Use Ns and Sx. -current is 4 not 3.

Bump configvers.h as a precaution. Although existing config files will
work unmodified still, new config files won't work on the old ones.

Bump configversion. The controller/device changes are upwards but not

Corresponding minimal changes for kernel configuration after new-bus
commit.

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.

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"

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.

* Change 'struct resource' to 'struct config_resource'.
* Bump config version.

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

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.
