kbuild: Support split debug info v4

2014-07-30T20:54:52+00:00

This is an alternative approach to lower the overhead of debug info
(as we discussed a few days ago)

gcc 4.7+ and newer binutils have a new "split debug info" debug info
model where the debug info is only written once into central ".dwo" files.

This avoids having to copy it around multiple times, from the object
files to the final executable. It lowers the disk space
requirements. In addition it defaults to compressed debug data.

More details here: http://gcc.gnu.org/wiki/DebugFission

This patch adds a new option to enable it. It has to be an option,
because it'll undoubtedly break everyone's debuginfo packaging scheme.
gdb/objdump/etc. all still work, if you have new enough versions.

I don't see big compile wins (maybe a second or two faster or so), but the
object dirs with debuginfo get significantly smaller. My standard kernel
config (slightly bigger than defconfig) shrinks from 2.9G disk space
to 1.1G objdir (with non reduced debuginfo). I presume if you are IO limited
the compile time difference will be larger.

Only problem I've seen so far is that it doesn't play well with older
versions of ccache (apparently fixed, see
https://bugzilla.samba.org/show_bug.cgi?id=10005)

v2: various fixes from Dirk Gouders. Improve commit message slightly.
v3: Fix clean rules and improve Kconfig slightly
v4: Fix merge error in last version (Sam Ravnborg)
    Clarify description that it mainly helps disk size.

.gitignore: ignore Module.symvers in all directories

2014-04-16T21:11:39+00:00

When using `make M=/path/to/driver modules` to build a module, file
Module.symvers will be created in that directory, so it's better to
ignore it in all directories.

Slightly reordered, let specific file names behind general ones.

gitignore: add all.config

This is used by kbuild to load preset Kconfig options.  We need to
ignore it, otherwise git clean kills it.

.gitignore: remove stale entry for generated version.h

2012-12-18T01:15:13+00:00

Since userspace headers were moved to generated/uapi it possible to have a
stale copy of linux/version.h at that file's old location.  This causes
confusion after building an older kernel version, then checking out and
building a new one; the old (stale) version header will still get picked
up until it is manually removed.  This upsets the C library.

Since the uapi changes, include/linux/version.h is no longer generated and
should not be ignored, so this patch removes it from .gitignore.

MODSIGN: Cleanup .gitignore

The module build process no longer creates intermediate files for module
signing, so remove them from .gitignore.

MODSIGN: Provide gitignore and make clean rules for extra files

2012-10-10T09:31:19+00:00

Provide gitignore and make clean rules for extra files to hide and clean up the
extra files produced by module signing stuff once it is added.  Also add a
clean up rule for the module content extractor program used to extract the data
to be signed.

kbuild: asm-generic support

2011-04-28T16:01:41+00:00

There is an increasing amount of header files
shared between individual architectures in asm-generic.
To avoid a lot of dummy wrapper files that just
include the corresponding file in asm-generic provide
some basic support in kbuild for this.

With the following patch an architecture can maintain
a list of files in the file arch/$(ARCH)/include/asm/Kbuild

To use a generic file just add:

        generic-y += 

For each file listed kbuild will generate the necessary
wrapper in arch/$(ARCH)/include/generated/asm.

When installing userspace headers a wrapper is likewise created.

The original inspiration for this came from the unicore32
patchset - although a different method is used.

The patch includes several improvements from Arnd Bergmann.
Michael Marek contributed Makefile.asm-generic.

Remis Baima did an intial implementation along to achive
the same - see https://patchwork.kernel.org/patch/13352/

.gitignore: ignore *.xz files

2011-02-22T16:18:53+00:00

Building with CONFIG_KERNEL_XZ results in the following:

 # Untracked files:
 #   (use "git add ..." to include in what will be committed)
 #
 #       arch/x86/boot/compressed/vmlinux.bin.xz

So ignore xz-compressed files at the top level like we already do for
other compression types.
