2006-07-03kbuild: introduce utsrelease.hSam Ravnborg1-12/+18
include/linux/version.h contained both actual KERNEL version and UTS_RELEASE that contains a subset from git SHA1 for when kernel was compiled as part of a git repository. This had the unfortunate side-effect that all files including version.h would be recompiled when some git changes was made due to changes SHA1. Split it out so we keep independent parts in separate files. Also update checkversion.pl script to no longer check for UTS_RELEASE. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-07-01kbuild: fix ia64 breakage after introducing make -rRSam Ravnborg1-1/+1
kbuild used $ยค(*F to get filename of target without extension. This was used in several places all over kbuild, but introducing make -rR broke his for all cases where we specified full path to target/prerequsite. It is assumed that make -rR disables old style suffix-rules which is why is suddenly failed. ia64 was impacted by this change because several div* routines in arch/ia64/lib are build using explicit paths and then kbuild failed. Thanks to David Mosberger-Tang <David.Mosberger@acm.org> for an explanation what was the root-cause and for testing on ia64. This patch also fixes two uses of $(*F) in arch/um Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-06-24kbuild: adding symbols in Kconfig and defconfig to TAGSMasatake YAMATO1-9/+25
I'm using TAGS generated from "make TAGS" to read the kernel source code. When I met a ifdef block #ifdef CONFIG_FOO ... #endif in the soruce code I would like to know the meaning CONFIG_FOO to decide whether I should read inside the ifdef block or not. meaning CONFIG_FOO is well documented in Kconfig. So it is nice if I can jump to CONFIG_FOO entry in Kconfig from "#ifdef CONFIG_FOO" with the tag jump. Here is the patch to add symbols in Kconfig and defconfig to TAGS in "make TAGS" operation.

2006-06-24kbuild: support for %.symtypes filesAndreas Gruenbacher1-1/+4
Here is a patch that adds a new -T option to genksyms for generating dumps of the type definition that makes up the symbol version hashes. This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes.

2006-06-24kbuild: fix silentoldconfig recursionRoman Zippel1-0/+4
kconfig-fix-config-dependencies causes this: make CC=cc KBUILD_VERBOSE=1 -C /usr/src/25 SUBDIRS=/home/akpm/NVIDIA-Linux-x86_64-1.0-8762-pkg2/usr/src/nv modules make -f /usr/src/devel/Makefile silentoldconfig make -f /usr/src/devel/Makefile silentoldconfig make -f /usr/src/devel/Makefile silentoldconfig The basic problem is if we compile external modules, config-targets isn't set which can cause recursive calls to silentoldconfig to update the kernel configuration.

2006-06-24kbuild: add option for stripping modules while installing themTheodore Ts'o1-0/+17
Add option for stripping modules while installing them. This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds. This patch allows such users to request modules_install to strip the modules as they are installed. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-06-18Basic implementation of 'make headers_check'David Woodhouse1-0/+4

2006-06-18Basic implementation of 'make headers_install'David Woodhouse1-0/+13
This adds a make target which exports a subset of headers which contain definitions which are useful for system libraries and tools. It uses the BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses sed to remove markers like __user.

2006-06-10kbuild: ignore make's built-in rules & variablesSam Ravnborg1-4/+3
kbuild does explicitly specify what to do in all cases, and each time make's built-in rules & variables has been used it has been a bug. So to speed up things and to avoid the hard-to-debug error situations ignore the built-in definitions. If any part of the kernel uses the built-in definitions the build will just stop there and it should be trivial to fix. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-06-09kbuild: add dependency on kernel.release to the package targetsZach Brown1-2/+2
The binrpm-pkg target uses KERNELRELEASE when generated its .spec file. When binrpm-pkg was the first build target run in a tree it generated the .spec before kernel.release so the Version: tag in the .spec was empty. I don't know if this is the best fix, but binrpm-pkg works when we explicitly build kernel.release before descending into package-dir.

2006-06-09kconfig: move .kernelreleaseRoman Zippel1-11/+10
This moves the .kernelrelease file into include/config directory.

2006-06-09kconfig: integrate split config into silentoldconfigRoman Zippel1-9/+2
Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

2006-06-09kconfig: fix .config dependenciesRoman Zippel1-16/+11
This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

2006-04-06kbuild: modules_install for external modules must not remove existing modulesAndreas Gruenbacher1-1/+0
When installing external modules with `make modules_install', the first thing that happens is a rm -rf of the target directory. This works only once, and breaks when installing more than one (set of) external module(s).

gcc should handle this anyways, and it causes problems when sprintf is turned into strcpy by gcc behind our backs and the C fallback version of strcpy is actually defining __builtin_strcpy Then drop -ffreestanding from the main Makefile because it isn't needed anymore and implies -fno-builtin, which is wrong now.
