Previous message: John Alvord: "Re: Linux, the microkernel (was Re: latest linus-2.5 BK broken)"

I suppose we won't see any official / -dj releases any time soon, since
everybody is at OLS, so I figured it may make sense to publish my
current tree, which fixes some outstanding build problems and adds more
cleanup.

Most notably:

make KBUILD_VERBOSE= bzImage

(or export KBUILD_VERBOSE=0 / setenv KBUILD_VERBOSE 0; make bzImage)

looks certainly improved now.

Fixes include:
o the defkeymap/loadkeys issue
o calling host programs for khttpd / soundmodem
o make net_dev_init() a subsys_initcall, to make sure it's called
before any net device registers.

Patch is available from

http://www.tp1.ruhr-uni-bochum.de/~kai/kbuild/patch-2.5.24-kg1.gz

bk pull http://linux-isdn.bkbits.net/linux-2.5.make

Feedback is very welcome, of course ;)

ChangeSet@1.490.1.62, 2002-06-20 11:57:34-05:00, kai@tp1.ruhr-uni-bochum.de
kbuild: Assorted cleanups

o Provide $(obj),$(objtree) and friends in the top-level Makefile as well
for consistency (Sam Ravnborg)
o Make $(call cmd,whatever) consistent with $(call if_changed,whatever),
i.e. both will execute $(cmd_whatever)
o Add $(echo_target), which will print the current target in a suitable
way for the quiet output format (i.e. target name relative to the
top-level directory)
o Fix the dependencies for host compiled programs to work for files in
subdirectories (missed converting them when introducing $(depfile))
o Add commands which will be useful when generating boot images.

kbuild: Prepare LDFLAGS for general use

Some arch Makefiles use LDFLAGS to keep special flags for the final
vmlinux link. However, we'd rather use LDFLAGS along the lines of
CFLAGS, AFLAGS etc, so get rid of these special cases.

-----------------------------------------------------------------------------
ChangeSet@1.490.1.64, 2002-06-20 12:25:11-05:00, kai@tp1.ruhr-uni-bochum.de
kbuild: Rename ld flags for vmlinux to LDFLAGS_vmlinux

Everywhere else we use CFLAGS_<target> etc to designate special flags
for an object, so handle vmlinux the same way.

ChangeSet@1.490.1.65, 2002-06-20 12:50:29-05:00, kai@tp1.ruhr-uni-bochum.de
kbuild: Put flags for ld into LDFLAGS

Some archs sneaked additional flags for ld into $(LD). This can be done
cleaner now, by just using $(LDFLAGS).

-----------------------------------------------------------------------------
ChangeSet@1.490.1.66, 2002-06-20 13:35:15-05:00, kai@tp1.ruhr-uni-bochum.de
kbuild: Put flags for objcopy into OBJCOPYFLAGS

Again, don't just add flags into $(OBJCOPY), but use the
variable $(OBJCOPYFLAGS) instead.

kbuild: clean up arch/i386/boot, part 1

Use the Rules.make provided objcopy command and untangle piggy.o
generation.

Unify zImage and bzImage generation.

kbuild: clean up arch/i386/boot, part 4

Use the provided rule for linking files and final polish.
Apart from being internally more logically structured,
"make KBUILD_VERBOSE= bzImage" output looks much improved now as
well.

kbuild: Add "make help" support

Added the new target "help" that list the most common targets
Calls down to Documentation/Makefile to list documentation targets.
Furthermore calls down to the architecture specific Makefile
to list architecture specific targets.
So far only i386 is supporting this.

kbuild: Fix calling of make_times_h and gentbl

make did normalize away the "./", so we better put the command
explicitly.

kbuild: Provide shipped versions of the keymap files

The keyboard maps are generated from appropriate .map files by running
loadkeys --mktable. However, there are two reasons to provide shipped
versions and use those by default

1) Not everybody has loadkeys installed.
2) As pointed out by Andries Brouwer, if changes to the tables occur in
the kernel tree, that may require a new/recompiled version of loadkeys,
so that the version of loadkeys required for the kernel build is
often ahead of the installed base.

For these reasons, we provide shipped versions of the generated files and
use them unless the user explicitly asks for regenerating by uncommenting
the appropriate line in the Makefile.

kbuild: Distribute "make clean" knowledge

Currently, the top-level Makefile needs to know about all generated
files in the sub directories in order to clean them up.

This patch adds the variable "clean-files" which can be used in the
subdir Makefiles instead, to list files which should be removed by
"make clean".

ChangeSet@1.609, 2002-06-23 12:40:50-05:00, kai@tp1.ruhr-uni-bochum.de
Make net_dev_init() a subsys_initcall()

This does make sure that net_dev_init() has been called before any
driver calls register_netdev().

Since net_dev_init() calls net_device_init() which in turn will initialize
old style built-in network drivers, it is important that the other
subsystems, PCI in particular are already initialized at this point.
This is currently guaranteed by the link order.
