Ulrich Spörlein 9c398cc7e0 mdoc: drop redundant .Pp calls, kill EOL whitespace 2010-10-09 11:43:00 +00:00
Ed Maste cbb9ebd738 Allow a kernel config to specify a set but empty value via
'makeoptions OPTION=' for consistency with the make commandline.

Previously 'makeoptions WERROR=' would result in a syntax error; now
it produces the same effect as 'makeoptions WERROR'.  Both forms now
result in 'WERROR=' in the generated Makefile.

Warner Losh 2d8084397f 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.

Warner Losh e21944b6bd Turns out that it is a bad idea to have a missing compat option be a
fatal condition.  While it works out really well for diagnosing the
case where you want it, but don't have it, it works really badly for
the case where you don't have it and don't want it.  Remove the printf
and exit pair.  Replate it with simple return to silently ignore this
condition.

This is needed to fix the COMPAT_IA32 being required in options.* in
stable, but we need to run this change through -current first...

Nathan Whitehorn 9b047d4a9a 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.

Warner Losh 28a24ccfa9 style(9) fixes:
o make cmd scoped to the whole do_rules function, since it really is
  scoped to the whole fucnion.  Making it static was the wrong way to
  fix referencing it outside of the block in which it was declared
  (and conforms to the style of the rest of the file).
o remove a couple of meaningless blank lines
o properly wrap one line.

Warner Losh 02b9c3f52f sparc64, and possibly other architectures, pads the length of the
section holding the config file to sh_addralign bytes using NULs.
This bogusly triggers an assert.  Break out of the loop when we hit an
NUL within that many bytes of the end.

Warner Losh 4bc2b0b76d Require the option that's mapped be listed in the options file. This
will allow people with old config options to either have it just work
(if config is new enough), or get a version error (if their config is
about 7.0 or newer) rather than getting a cryptic error about
duplicated options in the options file, or getting an error about an
unknown option, at which point they'd update their config file only to
learn they need a new config, only to learn they didn't really need to
update their config file...  All this because our version checking was
in the wrong place for the past decade...

# hopefully this is the last change, and we'll be able to config with an
# 8.0 GENERIC file on stable/8 after I merge this change and add the
# compat options.

Warner Losh 012ead2f2c Redo how we add compat options so as to be compatible with old
versions of config.  Remove support for the syntax OLD = NEW form the
options file, and instead have a new file $S/conf/options-compat.
This file will be parsed as OLD NEW on each line.  Bump version of
config.  Since nothing in -current ever used this, there's no hazards
for current users, so I'm not bumping the version in the
Makefiles.$MACHINE.  No need, really, for this version bump in
-current, but this was introduced into -stable before I realized the
version check was ineffective there, so the verison bump doesn't hurt
here and keeps the two branches in sync, versionwise, after the MFC.

Warner Losh 90aa4f9e8c Move checking the version up from Makefile generation to just after
we've parsed the config file.  Makefile generation is too late if
we've introduce changes to the syntax of the metafiles to warn about
version skew, since we have to try to parse them and we get an parse
error that's rather baffling to the user rather than a 'your config is
too old, upgrade' which we should get.

We have to defer doing it until after we've read the user's config
file because we define machinename there.  The version required to
compile the kernel is encoded in Makefile.machinename.  There's no
real reason for this to be the case, but changing it now would
introduce some logistical issues that I'd rather avoid for the moment.
I intend to revisit this if we're still using config in FreeBSD 10.

This also means that we cannot introduce any config metafile changes
that result in a syntax error or other error for the user until 9.0 is
released.  Otherwise, we break the upgrade path, or at least reduce
the usefulness of the error messages we generate.

# This implies that the config file option mapping will need to be redone.

with all other corresponding CTF places by changing the corresponding

Warner Losh bd34cda61a Bump minor version of config to reflect the new option remapping
feature.  The kernel makefiles have specifically not been bumped
because nothing uses this new feature and doing so forces everybody to
recompile for no good reason.  This chnage will be MFC'd where the
kernel version numbers for amd64 and ia64 will be bumped, since those
are the only two that have use the option remapping feature.  Once
merged, this will give a better error message to folks that are using
buildkernel without buildworld or kernel-toolchain to update their
kernels.

Warner Losh 91998fc549 Spring forward into the late 1970's by following item 5 in the yacc
manual's Appendix D ("Old Features Supported but not Encouraged") in
the Seventh Edition Unix Programmer's Manual (January, 1979) by
retiring the " = {" method of of action specification in favor of a
plain "{".  It is no longer necessary for this bootstrap program to
be compatible with 6th Edition systems.  Some yaccs in the wild do not
support this old syntax any more, and compatibility with those systems
is more important these days (as there are easily 7 orders of magnitude
more of them than real v6 systems today).

Wojciech A. Koszek 744b947ef8 Improve INCLUDE_CONFIG_FILE support.
This change will let us to have full configuration of a running kernel

	sysctl -b kern.conftxt

The same configuration is also contained within the kernel image. It can be
obtained with:

	config -x <kernelfile>

Current functionality lets you to quickly recover kernel configuration, by
simply redirecting output from commands presented above and starting kernel
build procedure. "include" statements are also honored, which means options
and devices from included files are also included.

Please note that comments from configuration files are not preserved by
default. In order to preserve them, you can use -C flag for config(8). This
will bring configuration file and included files literally; however,
redirection to a file no longer works directly.
