2006-02-19kbuild: make cc-version available in kbuild filesSam Ravnborg
Move $(CC) support functions to Kbuild.include so they are available in the kbuild files. In addition the following was done: o as-option documented in Documentation/kbuild/makefiles.txt o Moved documentation to new section to match new scope of functions o added cc-ifversion used to conditionally select a text string dependent on actual $(CC) version o documented cc-ifversion o change so Kbuild.include is read before the kbuild file Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-02-19kbuild: support building individual files for external modulesSam Ravnborg
Support building individual files when dealing with separate modules. So say you have a module named "foo" which consist of two .o files bar.o and fun.o. You can then do: make -C $KERNELSRC M=`pwd` bar.o make -C $KERNELSRC M=`pwd` bar.lst make -C $KERNELSRC M=`pwd` bar.i make -C $KERNELSRC M=`pwd` / <= will build all .o files and link foo.o make -C $KERNELSRC M=`pwd` foo.ko <= will build the module and do the modpost step to create foo.ko The above will also work if the external module is placed in a subdirectory using a hirachy of kbuild files.

2006-01-16[PATCH] sh: Move CPU subtype configuration to its own KconfigPaul Mundt
Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat. Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things like cache configuration are also moved to this new location. This also adds support for strict CPU tuning on newer cores, which requires the addition of as-option.

2006-01-16kbuild: fix 'make all install_modules install'Sam Ravnborg
The command 'make all modules_install install' would fail in a virgin tree - pointing at a non-existing directory under /lib/modules/xxx KERNELRELEASE is part of MODLIB and we need to create .kernelrelease before we can properly evaluate KERNELRELEASE, Changing MODLIB to the recursively expanded flavor let it pick up the correct KERNELRELEASE value.

2006-01-16kbuild: create .kernelrelease at *config stepSam Ravnborg
To enable 'make kernelrelease' earlier now create .kernelrelease when one of the *config targets are used. Also introduce KERNELVERSION - only user is kconfig. KERNELVERSION was needed to display kernel version in menuconfig - KERNELRELEASE is not valid until configuration has completed. kconfig files modified to use KERNELVERSION.

2006-01-15powerpc: Make ARCH=powerpc the default for 32-bit ppcPaul Mackerras
This makes ARCH=powerpc the default on 32-bit powerpc machines, where uname -m returns ppc, as well as on 64-bit powerpc machines. Most people who would be likely to build their own kernels on 32-bit powerpc machines would be using powermacs or CHRP machines, both of which are supported with ARCH=powerpc now. Embedded ppc developers whose ports haven't been moved over to arch/powerpc yet will have to explicitly set ARCH=ppc now. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-01-09kbuild: KERNELRELEASE is only re-defined when buiding the kernelSam Ravnborg
To avoid running setlocalversion as root no longer (re-)define KERNELRELEASE for each run. With this patch KERNELRELEASE is only re-read when we do an actual kernel build. Rationale behind this is "do as little as possible" when executing make install - as root! A new file named .kernelrelease is strored in the root of the kernel tree containing the actual version string. So when we use do a kernel build the .kernelrelease file will be updated. But in all other situations it is left as-is. To make it more visible the kernel now prints out the version being build. Sample: Building kernel 2.6.15-g63b794bf-dirty ... ... The patch also un-exports VERSION PATCHLEVEL SUBLEVEL EXTRAVERSION LOCALVERSION since all users of these are anyway broken - and none is left in the tree.

2005-12-26kbuild: always run 'make silentoldconfig' when tree is cleanedSam Ravnborg
If the file .kconfig.d is missing then make sure to run 'make silentoldconfig', since we have no way to detect if a Kconfig file has been updated. -kconfig.d is created by kconfig and is removed as part of 'make clean' so the situation is likely to occur in reality.

2005-11-13[PATCH] Kbuild: index asm-$(SUBARCH) headers for UMLPaolo 'Blaisorblade' Giarrusso
In Uml, many definitions are borrowed from underlying subarch headers (with #include <asm/arch/stuff.h>). And it has become annoying to keep switching tag files all time, so by default index the underlying subarch headers too. Btw, it adds negligible space to the tags file (less than 1M surely, IIRC it was around 500k over 40M). Finally, preserve the ALLSOURCE_ARCHS command line option (I hope) - if it is set, it is used for headers too as before. But check my construct please, I didn't test this.

2005-11-11ppc64: default build as the merged 'powerpc' architectureLinus Torvalds
After the last merge of the new unified 'powerpc' architecture, ppc64 no longer compiles cleanly as a standalone architecture. Some bits and pieces still exist as files under the old ppc64 hierarchy, but the old "ARCH=ppc64" is dead. So if "uname" says ppc64, that now implies that the default architecture should be "powerpc".

2005-11-10[PATCH] kbuild: build breaks after -imacros was introducedZachary Amsden
I have to revert the recent addition of -imacros to the Makefile to get my tool chain to build. Without the change, below, I get: Note that this looks entirely like a toolchain bug. Here is the offending command: [pid 12163] execve("/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", ["/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", "-lang-asm", "-nostdinc", "-Iinclude", "-Iinclude/asm-i386/mach-default", "-D__GNUC__=3", "-D__GNUC_MINOR__=2", "-D__GNUC_PATCHLEVEL__=2", "-D__GXX_ABI_VERSION=102", "-D__ELF__", "-Dunix", "-D__gnu_linux__", "-Dlinux", "-D__ELF__", "-D__unix__", "-D__gnu_linux__", "-D__linux__", "-D__unix", "-D__linux", "-Asystem=posix", "-D__NO_INLINE__", "-D__STDC_HOSTED__=1", "-Acpu=i386", "-Amachine=i386", "-Di386", "-D__i386", "-D__i386__", "-D__tune_i386__", "-D__KERNEL__", "-D__ASSEMBLY__", "-isystem", "/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include", "-imacros", "include/linux/autoconf.h", "-MD", "arch/i386/kernel/.entry.o.d", "arch/i386/kernel/entry.S", "-o", "/tmp/ccOlsFJR.s"] Which should execute properly, I think. But it does not: zach-dev:linux-2.6.14-zach-work $ make CHK include/linux/version.h CHK include/linux/compile.h CHK usr/initramfs_list AS arch/i386/kernel/entry.o /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0: output filename specified twice make[1]: *** [arch/i386/kernel/entry.o] Error 1 make: *** [arch/i386/kernel] Error 2 gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) Deprecating the -imacros fixes the build for me. It does not appear to be a simple argument overflow problem in trapcpp0, since deprecating all the defines reproduces the problem as well. Also, switching -imacros to -include fixes the problem.

2005-11-06[PATCH] kbuild: permanently fix kernel configuration include messRussell King
Include autoconf.h into every kernel compilation via the gcc command line using -imacros. This ensures that we have the kernel configuration included from the start, rather than relying on each file having #include <linux/config.h> as appropriate. History has shown that this is something which is difficult to get right. Since we now include the kernel configuration automatically, make configcheck becomes meaningless, so remove it.
