"make bzImage && sudo make install" had the problem that during
the "sudo make install" the build system would notice that the information
in include/linux/compile.h is not accurate (it says "compiled by <user>",
but we are root), thus causing compile.h to be updated and leading to
some recompiles.
We now only update "compile.h" if the current user is the owner of
include/linux/autoconf.h, i.e. the user who did the "make *config". So the
above sequence will correctly state "compiled by <user>".

Removed unused targets to CHMOD_FILES in scripts
This allow a fresh kernel to start the build process without
bailing about docgen.
|
|
This is the first patch in a serie to clean-up the DocBook
Makefile.
docproc is extented to include the functionality previously provided by
gen-all-syms and docgen. Furthermore the necessity to specify which
files to search for EXPORT_SYMBOL are removed, the information is now
read in the .tmpl files.
docproc is furthermore extended to generate dependency information.
gen-all-syms and docgen are deleted.

During processing of skbuff.h three warnings were issued,
because members of an enum within a struct were nor documented.
This patch fixes kernel-doc not to spit out these non-valid warnings.

The following trivial patch makes the patch-kernel script executable by
a bare bone POSIX shell like ash. Either that, or the interpreter line
has to be changed to /bin/bash.
The same patch applies to 2.4 (with some line offset).

Reduce the amount of output in verbose (default) mode and stop
immediately on error.

New and old way to handle dependencies would choke when a file
#include'd by other files was removed, since the dependency on it was
still recorded, but since it was gone, make has no idea what to do about
it (and would complain with "No rule to make <file> ...")
We now add targets for all the previously included files, so make will
just ignore them if they disappear.

fixdep does a sanity check to make sure that it got endianness
and sizeof(int) right. As opposed to the main loops, this sanity
check forgot to ensure proper alignment.

cpp -MD guesses the target name from the source file name, but not
always correctly, e.g. when compiling fixdep, it generates prequisites
for fixdep.o instead of fixdep.
fixdep now fixes up the -MD generated output to contain the right target,
which is the one we pass on the command line.
|
|
o Fix a bug in fixdep.c, which could cause segfaults
o Make sure that we build fixdep first of all, since
we need it to build host programs.
|
|
by Sam Ravnborg:
fixdep, when adding dependencies to config entires fails to take into account
the last part of a config entry, if it contains more than one underscore.
Example:
CONFIG_PROC_FS generates
$(wildcard include/config/proc.h)
but should generate
$(wildcard include/config/proc/fs.h)
Attached patch fixes this.

At a couple of places, we need to build programs which run on the
compile host during building the kernel.
Add a new variable "host-progs" to declare such programs. Rules.make will
automatically provide rules to compile these programs with appropriate
command lines etc.
Compared to having explicit rules spread around for doing so, this has
the following advantages:
o shorter
o automatically figures out dependencies and handles changing command
lines
o Nicer output in quiet mode ;-)
Compiling host programs from multiple sources is also possible, analogous
to multi-part objects. E.g. scripts/Makefile has
host-progs := tkparse
tkparse-objs := tkparse.o tkcond.o tkgen.o

Patch by Keith Owens, ported to 2.5.
If the length of $(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION)
exceeds 64 characters it silently corrupts the utsname data, resulting
in garbage for uname -r and problems running the kernel and modules.
Abort if KERNELRELEASE is too long. Truncation is not good enough, it
results in ambiguous /lib/modules/`uname -r` contents.
Ensure that the date/time in uname are always in LANG=C. Users with
other languages report that 8 bit values cause the boot messages to go
haywire.
|
|
Not that it matters, since it's only used with 7bit chars, but
anyway.

This patch adds the following targets, which generate some configs
useful for testing - which kind should be clear from the names:
o allyesconfig
o allmodconfig
o allnoconfig
o randconfig
It also adds
o defconfig
which does the same as make oldconfig but uses the defaults for all
new options without asking.
The actual patch was done by Ghozlane Toumi, maintained in kbuild-2.5
by Keith Owens, and extracted by Sam Ravnborg and patch@luckynet.dynu.com.

For some cases, we cannot decide if a target would change just by looking
at its prequisites, i.e. it's quite likely that it remains the same
even though a prequisite changed. The updated timestamp would cause
a lot of unnecessary recompiles. In this case, we actually generate
a temporary file, compare it to the old file and only the contents
are different do overwrite the old file.
The "update-if-changed" snippet remains always the same, so let's
put it into a macro instead of duplicating it. After that change,
scripts/mkversion_h is so small that we rather put the three remaining
lines directly into the Makefile.

Making dependencies once up front is not ideal. For one, you don't need
them initially, since when you don't have the .o file, you bet you have
to build it no matter what the dependencies say - dependencies are about
deciding when to *re*build.
There's more reasons, like:
o you don't even know which files you'll build, so you have to go over
all files (even over drivers/{sbus,s390,...} on i386)
o generated files don't exist yet, so you cannot pick up dependencies
on them
o even if dependencies are right initially, they change when you work on
your tree or patch it, and nobody will notice unless you run "make dep"
explicitly again
Anyway, gcc knows hows to emit a correct dependency list, so we just use
that. Well, a little bit of hacking is necessary to remove the dependency
on autoconf.h and put in individual CONFIG_WHAT_EVER dependencies instead,
since otherwise changing one config option would cause everything to be
rebuilt.
I should add that I didn't come up with this all by myself, most work
is actually done in gcc and there were discussions about using -MD on
kbuild-devel way back, so I should mention Keith Owens and Michael
Elizabeth Chastain, and probably others that I forgot, so I apologize
just in case.

We source some scripts, but still pass parameters to them, e.g.
. mk_version_h $@ $(KERNELRELEASE) $(VERSION) ...
This does not work for all kinds of /bin/sh (it does for bash, that's
why I did not notice).
The fix is easy: Just mark the scripts executable and call instead of
source them.
Unfortunately, patch(1) doesn't understand about propagating chmod.
bk does, so changing the tree isn't hard, and we introduce an explicit
chmod a+x executed during the build for propagating this change into
those trees which get "traditionally" patched up.

Just use 'make some/dir/foo.lst' to produce mixed source code and
assembly for debugging. (If the object gets linked in and you have
a System.map, it'll relocate appropriately)
Apart from the needed Makefile bits, also clean up the script
"makelst".
|
|
Suppress echoing of commands when using "make -s", so that make -s
does indeed have the effect one would expect.
Add a quiet mode, which will print not the entire command but only
one line per rule. To turn it on, use
make KBUILD_VERBOSE=0 vmlinux/whatever
or set KBUILD_VERBOSE=0 in your environment.
For now, the verbose mode is default, which gives you the old behavior
of printing all commands.
The output in quiet mode is based on what Keith Owens' kbuild-2.5 does,
I like, I did not want to invent yet another output format.

Targets should always be built from the Makefile local to the subdir
they are in. So build scripts/* from scripts/Makefile.
Clean up scripts/Makefile as we go.
|
|
FORCE is the de-facto standard name for a prequisite to force
recompilation, so instead of using a mix of 'dummy','FORCE' and
'FORCE_RECOMPILE' use 'FORCE' everywhere.
Also, move figuring out the path relative to the top level dir
into Rules.make, instead of calling an external script.
|
|
|
|
Before overwriting version.h, check if it actually changed - otherwise
we will unnecessarily rebuild a lot of files, as e.g. module.h depends
on version.h, and many files include module.h
|
|
There's no good reason to build the objects in init/ explicitly from
the top-level Makefile. Instead, handle init/ like every other
subdir, which also provides the automatic checks for a changed
command line etc.
|
|
init/version.o includes include/linux/compile.h. As compile.h was
regenerated each time make was run, init/version.o was recompiled each
time.
To avoid this, use the following solution: Generate a temporary new
compile.h, and only replace the old one if the new one is different.
We consider the files different if more than just date/time changed, since
otherwise we would have to rebuild every time anyway.
Still, the two files turned out to be different all the time, as we put
a generation number into them which is incremented at each invocation of
"make". The generation number update is now only done when the kernel
config changes, which makes more sense, anyway.
So, the UTS_VERSION and generation number now relate to the time the
kernel was configured, not the time the actual "make vmlinux" was run,
which should be fine.
|
|
Also, put the #define UTS_MACHINE ... from the command line into
the header as well.
|
|
Try to get config file distro placed in boot.
|
|
We now have so many CONFIG_ options we overflow a buffer in xconfig.
Doubling the size should see us until someone either writes a replacement,
or can be bothered to make it dynamically allocate.

in /etc/kernel-config, and only if that fails in the architecture-
specific defconfig.

- install .config in /boot
- provide kernel-drm package if drm is compiled
- handle extra '-' marks so that linux-2.5.8-dj3-voon works.
