Bump config(8) version and build requirement for config(8) to 600006. This

The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers. This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
(all tw_cl* files), which is a consolidation of all OS-independent
parts of the driver. The FreeBSD OS specific portions of the
driver go into an "OS Layer" (all tw_osl* files).
This re-architecture is to achieve better maintainability, consistency
of behavior across OS's, and better portability to new OS's (drivers
for new OS's can be written by just adding an OS Layer that's specific
to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
include Online Capacity Expansion and multi-lun support, among others.
More details about 3ware's 9.2 release can be found here:
http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files. For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.

Move machine link creation from genassym to kernel-depend, per nyan@

Arrgh. A clean pc98 build failed due to bogons on my part :-(.

Fix it by putting back the link of machine to sys/i386/include rather

on my first test.

Not sure what the "right" fix is, but this unbreaks things.

Factor the common parts of the Makefile.foo files. This introduces two
new files: kern.pre.mk, which contains most of the definitions, and

With this commit, I hereby pronounce gensetdefs past its use-by date.

Replace the a.out emulation of 'struct linker_set' with something
a little more flexible. <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set. They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated. This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

The kernel is now known as `kernel.ko' and it and its matching modules

* Create entire directory path for modules.
* Don't ignore error returns.

-mkdir the ${DESTDIR}/modules directory upon modules-install in case it

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!

supports All Cyrix CPUs, IBM Blue Lightning CPU and NexGen (now AMD)
Nx586 CPU, and initialize special registers of Cyrix CPU and msr of
IBM Blue Lightning CPU.

If revision of Cyrix 6x86 CPU < 2.7, CPU cache is enabled in
write-through mode. This can be disabled by kernel configuration
options.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Synchronize with Makefile.i386 revison 1.91.

Re-sync with -current. Should be in 2.2.

Another round of merge.

(1) Bug fix (pass boot drive):

pc98/boot/biosboot/boot2.S

(2) Delete code for unsupported high-resolution modes and move old
Epson notebook code to epsonio.h:

pc98/boot/biosboot/io.c
pc98/i386/vm_machdep.c
pc98/pc98/fd.c
pc98/pc98/pc98.c
pc98/pc98/pc98.h
pc98/pc98/epsonio.h (new)

(3) Change aic driver so that PCMCIA cards (I/O port same as PC/AT)
and PC-9801-100 cards can be selected with a flag in kernel config
file:

pc98/pc98/aic6360.c
pc98/pc98/aic_98.h (new)

(4) Fix wcd entry (it was broken). Delete mcd, it doesn't work on

(9) Enable workaround for Cyrix bug for 5x86 also:

pc98/i386/machdep.c
pc98/i386/trap.c

All the above deletes this file too:

pc98/i386/pmap.c
