2007-07-25kbuild: use LDFLAGS_MODULE only for .ko linksRoland McGrath
Sam Ravnborg pointed out that Documentation/kbuild/makefiles.txt already says this is what it's for. This patch makes the reality live up to the documentation. This fixes the problem of LDFLAGS_BUILD_ID getting into too many places. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-07-25kbuild: do not do section mismatch checks on vmlinux in 2nd passSam Ravnborg
We already check and warn about section mismatches from vmlinux (build as vmlinux.o) during first pass so skip the checks during the 2nd pass where we process modules. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-07-17kbuild: do section mismatch check on full vmlinuxSam Ravnborg
Previously we did do the check on the .o files used to link vmlinux but that failed to find questionable references across the .o files. Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only. For a defconfig build this is instant but for an allyesconfig this add two minutes to a full build (that anyways takes ~2 hours). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-02kbuild: fix section mismatch check for vmlinuxSam Ravnborg
vmlinux does not contain relocation entries which is used by the section mismatch checks. Reported by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Use the individual objects as inputs to overcome this limitation. In modpost check the .o files and skip non-ELF files.

2006-10-17[PATCH] kbuild: allow multi-word $M in Makefile.modpostGreg Banks
Some people want to do crazy things like pass multiple directories as the value of $(SUBDIRS) or $M. Mostly this kinda works, except that Makefile.modpost constructs a modpost commandline which fails modpost's argument parsing. This patch fixes that little wrinkle.

2006-10-01kbuild: make modpost processing configurableSam Ravnborg
On request from Al Viro make modpost processing configurable. KBUILD_MODPOST_WARN can be set to make modpost warn instead of error out in case on unresolved symbols in final module link. KBUILD_MODPOST_NOFINAL can be set to avoid the final and timeconsuming .c file generation and link of .ko files. This is solely useful for speeding up when doing compile checks with for example allmodconfig Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-25kbuild: fail kernel compilation in case of unresolved module symbolsKirill Korotaev
At stage 2 modpost utility is used to check modules. In case of unresolved symbols modpost only prints warning. IMHO it is a good idea to fail compilation process in case of unresolved symbols (at least in modules coming with kernel), since usually such errors are left unnoticed, but kernel modules are broken. - new option '-w' is added to modpost: if option is specified, modpost only warns about unresolved symbols - modpost is called with '-w' for external modules in Makefile.modpost Signed-off-by: Andrey Mirkin <amirkin@sw.ru> Signed-off-by: Kirill Korotaev <dev@openvz.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-25kbuild: modpost on vmlinux regardless of CONFIG_MODULESSam Ravnborg
Based on patch from: Magnus Damm <magnus@valinux.co.jp> This has the advantage that all section mismatch checks are run regardless of modules being enabled or not. When running modpost on vmlinux output: MODPOST vmlinux When running modpost on modules output count of modules like this: MODPOST 5 modules Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-07-01kbuild: fix ia64 breakage after introducing make -rRSam Ravnborg
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>
2006-06-26Revert "kbuild: fix make -rR breakage"Linus Torvalds
This reverts commit e5c44fd88c146755da6941d047de4d97651404a9. Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem. Daniel says: "[The] reason is a recent change that made modules always shows as module.mod. it breaks modprobe and probably many scripts..besides lsmod looking horrible stuff like this in modprobe.conf: install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia makes modprobe fork/exec endlessly calling itself...until oom interrupts it" Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-24kbuild: fix make -rR breakageSam Ravnborg
make failed to supply the filename when using make -rR and using $(*F) to get target filename without extension. This bug was not reproduceable in small scale but using: $(basename $(notdir $@)) fixes it with same functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-06-09kconfig: fix .config dependenciesRoman Zippel
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.

2006-03-05kbuild: change kbuild to not rely on incorrect GNU make behaviorPaul Smith
The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

2006-02-19kbuild: improved modversioning support for external modulesSam Ravnborg
With following patch a second option is enabled to obtain symbol information from a second external module when a external module is build. The recommended approach is to use a common kbuild file but that may be impractical in certain cases. With this patch one can copy over a Module.symvers from one external module to make symbols (and symbol versions) available for another external module. Updated documentation in Documentation/kbuild/modules.txt Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2005-07-25kbuild: introduce Kbuild.includeSam Ravnborg
Kbuild.include is a placeholder for definitions originally present in both the top-level Makefile and scripts/Makefile.build. There were a slight difference in the filechk definition, so the most videly used version was kept and usr/Makefile was adopted for this syntax. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> ---
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
