from .c files. Actually, this is overkill, as the .ln file targets
are assumed from .? (any) files. This is not a problem in practice,
merely a bit untidy, as the linting rules DTRT. See the sys/conf/*
and sys/mk/* files for usage.
and due to buffering they would sometimes come out after the actual
error message when mkheaders() failed due to an unknown device, so you'd
get an error messages followed by 20 or 30 lines of harmless warnings.
There are lots of other warning messages in config(8) that are printed
on stdout, but these were the most egregious (at least with LINT).
Fixed memory leak in the "nodevice" option implementation.
Use these instead of sed(1) in MD NOTES.
Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures. (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)
Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):
- i386 LINT lost "device pst".
- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
options, and got needless DPT_* options.
- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
to sparc64 LINT so that it has a chance to config(8).
This basically returns us to where we were before.
(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.
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.
stealth hints loading. 'make release' has been fixed to not need this

Hey! Why did it suddenly get so dark??
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.

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.
for your /usr/obj/path/to/my/files path to the kernel, then weird
things happened. make buildkernel would fail because config was
dumping core or generating bad file names (depending on the lenght of
the path).
While I was here, also use strlcpy, strlcat and snprintf (or asprintf)
as necessary. Minor format policing for the snprintf calls as well.
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!

the need to specify the unit number of unwired devices. ie: instead
of saying "device fxp0" we can say "device fxp" which is much closer
to what it actually means. The former (fxp0) implied something about
reserving the 0th unit, but it does not and never did - it was a
figment of config(8)'s imagination that we had to work around..
"device fxp0" simply means "compile in the fxp device driver", so we
may as well just write it as "device fxp" which is closer to what it
really means.
Doing this also saves us from filling up the ioconf.c tables with
meaningless entries.

This would mean that we could move files.alpha, files.i386, files.pc98
etc all next to conf/files, and the various Makefiles next to each
other. This should go a long way towards committers "seeing" the
Alpha etc stuff and remembering to update that too as it would be
right next to the i386 config files. Note this does not include
the GENERIC etc files as they can't be shared. I haven't actually
moved the files, but the support is here for it. It still supports
the per-machine conf directories so that folks working on a new arch
can just distribute a subdir of files.
- 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.

files in a 'files.XXX' file, config allows non-FreeBSD source files
with the same name as a FreeBSD source file to override the latter,
and in this situation it issues a warning.
However, if one of the user-specified files is actually a FreeBSD
source file (perhaps your kernel has some custom option that requires
that file), config mistakenly thinks it's a completely new file
and goes ahead and overrides all previous information for that file
(and issues the warning).
Fix this.
