2005-09-11kbuild: fix silentoldconfig with make O=Sam Ravnborg
Al Viro reported that sometimes silentoldconfig failed because output directory was missing. So create it unconditionally before executing conf Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-09-11kbuild: rename prepare to archprepare to fix dependency chainSam Ravnborg
When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

2005-09-10[PATCH] kbuild: fix split-include dependencyJan Beulich
Splitting of autoconf.h requires that split-include was built before, and needs to be-re-done when split-include changes. This dependency was previously missing. Additionally, since autoconf.h is (suppoosed to be) generated as a side effect of executing config targets, include/linux should be created prior to running the respective sub-make.

2005-09-10[PATCH] kbuild: adjust .version updatingJan Beulich
In order to maintain a more correct build number, updates to the version number should only be commited after a successful link of vmlinux, not before (so that errors in the link process don't lead to pointless increments).

2005-09-09kbuild: full dependency check on asm-offsets.hSam Ravnborg
Building asm-offsets.h has been moved to a seperate Kbuild file located in the top-level directory. This allow us to share the functionality across the architectures. The old rules in architecture specific Makefiles will die in subsequent patches. Furhtermore the usual kbuild dependency tracking is now used when deciding to rebuild asm-offsets.s. So we no longer risk to fail a rebuild caused by asm-offsets.c dependencies being touched. With this common rule-set we now force the same name across all architectures. Following patches will fix the rest. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2005-08-10[PATCH] kbuild: automatically append a short string to the version based ↵Ryan Anderson
upon the git commit If CONFIG_AUTO_LOCALVERSION is set, the user is using a git-based tree, and the current HEAD is not referred to by any tags in .git/refs/tags/, append -g and the first 8 characters of the commit to the version string. This makes it easier to use git-bisect, and/or to do a daily build, without trampling on your older, working builds, or accidentally setting up conflicting sets of modules.

2005-07-27kbuild: silence mystery messageSam Ravnborg
During last phase of the build the following message were displayed: /bin/sh: +@: command not found This message appears due to slightly changed semantics of cmd and if_changed_rule. The easy fix was to insert a dummy command first in rule_ksym_ld. The alternative was to redo part of this processing in the top-level Makefile - a volatile area that I try to avoid.

2005-07-14kbuild: Don't fail if include/asm symlink existsSam Ravnborg
From: Andreas Gruenbacher <agruen@suse.de> We're having the following situation: There are user-space applications that include kernel headers directly. With a completely unconfigured /usr/src/linux tree, including most headers fails because essential files are not there: include/asm include/linux/autoconf.h include/linux/version.h So we create these files. On the other hand, we want to use /usr/src/linux as read-only source for building kernels or additional modules. Now when building a kernel with a separate output directory (O=), there is a check in the main makefile for the include/asm symlink. There is no real need for this check: if we ensure that $(objdir)/include/asm is always created as the patch does, $(srctree)/include/asm becomes irrelevant.

2005-07-13[PATCH] kbuild: allow cscope to index multiple architecturesIan Campbell
I have a single source tree which I cross compile for a couple of different architectures using ARHC=foo O=blah etc. The existing cscope target is very handy but only indexes the current $(ARCH), which is a pain since inevitably I'm interested in the other one at any given time ;-). This patch allows me to pass a list of architectures for cscope to index. e.g. make ALLSOURCE_ARCHS="i386 arm" cscope This change also works for etags etc, and I presume it is just as useful there.

2005-07-13[PATCH] kbuild: make 'cscope -q' play well with cscope.elKarl Hegbloom
I tried the Linux Makefile 'make cscope' target, and found that the generated database is not compatible with 'cscope.el' under XEmacs. The thing is that 'cscope.el' does not allow setting the command line options to the 'cscope' commands it runs, and it errors with a message about the options not matching the ones used to generate the index. It turns out the cscope designers already thought of this. The options can be written into the "cscope.files". The included patch moves the "-q" and "-k" options from the 'cmd_cscope' to the 'cmd_cscope-file', echoing them into the top of the files listing. Now the index is generated with the "-q" option, and when 'cscope.el' performs it's search, it uses that argument as well. Lookups are fast and everyone is happy.

The arch Makefile may override the include path order, which is used by Xen (and UML?) to make sure include/asm-xen is searched before include/asm-i386.

I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the "cmd_tags" variable has been changed in a way incompatible with *emacs ctags.

2005-04-30[PATCH] kbuild: Set NOSTDINC_FLAGS late to speed up compile (a little)Sam Ravnborg
Move definition of NOSTDINC_FLAGS below inclusion of arch Makefile, so any arch specific settings to $(CC) takes effect before looking up the compiler include directory.

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!
