6c205e59db Delete the 'device-driver' suffix. It's been meaningless for a long time.
On the VAX, it used to be used for special compilation to avoid the
optimizer which would mess with memory mapped devices etc.  These days
we use 'volatile'.

37558b0171 Move a couple of bits of (now) static content from config(8) (ie: %LOAD)
directly into the Makefile.  Remove references to swapkernel.c, it's
not generated by config(8) now.  (The previous config commits had
generated it, but they had an unused 'char *' in them).

b307e58fc7 Major lobotomy of config(8). The
config kernel mumble mumble

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.

ALPHA/PC98 people:  You will have to adapt a few simple changes
(defining rootdev and dumpdev somewhere else) before config works
for you again, sorry, but it's all in the name of progress.

6d04a6cb97 I'm sick of the automatic rename of /kernel to /kernel.old while doing
development that leads to lots of crashes during boot.

I have made a 'reinstall' target (like in ports, and reinstall.debug)
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
for development, not general users.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
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.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

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.

2005b07aa8 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.

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

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).
