kbuild-next content

[Sam Ravnborg]

I have been offline for a while - but found some time this weekend
to do some kbuild work.
This is the patches that has accumulated in kbuild-next so far.

I have almost everything applied that I had queued up.
So if there is something missing assume I deleted it by mistake
and resend it to me.

I have a number of patches sitting in my local trees but
I need to look over them once more before they are ready
for public review.
This is mostly related to generated headers and simplfied
vmlinux.lds scripts (Tim is eagerly await this...).

Patches will follow.

[PATCH 01/39] kconfig: handle comment entries within choice/endchoice

[Sam Ravnborg]

From: Peter Korsgaard <jacmet@sunsite.dk>

Implement support for comment entries within choice groups. Comment entries
are displayed visually distinct from normal configs, and selecting them is
a no-op.

Not all architectures prepend the $(boot) path in $(KBUILD_IMAGE).
Allow for that fact in the builddeb script. Example is arm.

[PATCH 05/39] kbuild, deb-pkg: pass Debian maintainer script parameters to packaging hook scripts

[Sam Ravnborg]

From: Frans Pop <elendil@planet.nl>

The Debian packaging scripts created by the deb-pkg target do not pass
on the standard Debian maintainer script parameters to hook scripts,
which means that those scripts cannot tell whether they are being called
during e.g. install vs. upgrade, or removal vs. purge of the package.

As there are several variantions in how hook scripts are called from
kernel packages, we pass the parameters in the environment variable
DEB_MAINT_PARAMS rather than as extra arguments.

Bump version of builddep script to 1.3.

[PATCH 10/39] kbuild, deb-pkg: improve maintainer identification

[Sam Ravnborg]

From: maximilian attems <max@stro.at>

Try harder to find email and maintainer name.
Debian's own devscripts all use DEBEMAIL or DEBFULLNAME prior to an
eventual EMAIL or NAME environment variable. Match their logic.

"Anonymous" sounds nicer then "Kernel Compiler" if no name is found.

[PATCH 17/39] kbuild: fix header export when __ASSEMBLY__ is used

[Sam Ravnborg]

unifdef got confused by:

Because it does not know __ASSEMBLY__ it does not
detect that htis is not for userspace.
This caused too much code to be exported, and headers_check barfed
over this code.

For arm this fixes following "make headers_check" warning:
/usr/include/asm/hwcap.h:29: extern's make no sense in userspace

Russell King suggested to undefine __ASSEMBLY__ to fix this warning.

Are you sure that this is safe for all user space? If a user application
for instance includes asm/signal.h or asm/types.h from assembly (for
whatever reason), it now breaks.

I can't think of a good reason why anyone would do such a thing,
but it used to be possible.

I also want to add :

__KERNEL__ and __ASSEMBLY__ is used for specific purpose, please do not
mix them otherwise it leads to confusion and people will start using
interchangeably. It seems to me that you are introducing Pink traffic
light for stoppage so my request is to respect the protocols.

I do not think it is safe and this will screw some user-space apps and
then later on kernel.

I had not thought about this implication.
I will drop the patch as this most likely
will break some userspace.

So now go back and re-read my original email.  I was not suggesting to
undefine __ASSEMBLY__ - I was more detailed in my _question_ which I
was making, and there were _two_ possibilities.

I still think this is pointless and should just be removed

[PATCH 19/39] kbuild: clean up scripts/headers.sh

[Sam Ravnborg]

From: Amerigo Wang <amwang@redhat.com>

'drop' variable is unused.

'ppc' and 'sparc64' directories don't exist in arch/,
and I think their headers can be well exported now, so
just remove them.

[Sam Ravnborg]

From: Jiri Slaby <jirislaby@gmail.com>

- getcwd returns path without a slash at the end, add the slash
- add KBUILD_SRC env support, so that we can specify path for
  kernel (to know where scripts/kernel-doc resides) and SRCTREE
  (for searching files referenced in .tmpl) separately

[v2]
- use KBUILD_SRC instead of a newly introduced environment variable

[PATCH 22/39] kbuild: remove extra ifdef/endif of top Makefile

[Sam Ravnborg]

From: Cheng Renquan <crq@kernel.org>

The GNU make's origin function know undefined variable well,
so the outer ifdef/endif conditional checking is unneeded.

>From `info make` documentation, origin will return

  `undefined'
     if VARIABLE was never defined.
  `command line'
     if VARIABLE was defined on the command line.
   ...

Therefore, $(origin V) will get a value anyway, killing ifdef/endif is
viable and safe.

Furthermore, I've checked the minimal requirements from
Documentation/Changes is GNU make 3.79.1, and that version of GNU make
has support of origin function well already, so now it's safe to kill
the outer conditional checking, without upgrading the minimal
requirements.

From: Markus Heidelberg <markus.heidelberg@web.de>

All the KCONFIG_ environment variables were previously located in a
section "Environment variables in 'menuconfig'", but neither are they
restricted to 'menuconfig' nor are they all used by 'menuconfig'.

Introduce the following three sections for these variables:
  * Environment variables for '*config'
  * Environment variables for '{allyes/allmod/allno/rand}config'
  * Environment variables for 'silentoldconfig'

Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a
common section "User interface options for 'menuconfig'".

[PATCH 27/39] kconfig qconf: fix -Wall compiler warnings

[PATCH 28/39] kconfig qconf: fix namespace for Horizontal and Vertical enum values

[Sam Ravnborg]

From: Markus Heidelberg <markus.heidelberg@web.de>

They were used as QSplitter::Horizontal resp. QSplitter::Vertical, but
are defined in the 'Qt' namespace.

Fixes the following compiler errors after a quick conversion with 'qt3to4',
which occured with g++ 3.4.6 and 4.1.2, but not anymore with 4.3.2.

[PATCH 31/39] kconfig: do not hardcode ".config" filename

[Sam Ravnborg]

From: Markus Heidelberg <markus.heidelberg@web.de>

Rather than hardcoding ".config" use conf_get_configname(), which also
respects the environment variable KCONFIG_CONFIG.

This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also
suggests the given filename for "Load" and "Save as" in qconf.

[PATCH 32/39] kconfig: do not hardcode "include/config/auto.conf" filename

[Sam Ravnborg]

From: Markus Heidelberg <markus.heidelberg@web.de>

Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target
into "include/config/auto.conf.cmd" was always the default one.

Of course this doesn't make it work for the Kernel kbuild system, since
there the filename is hardcoded at several places in the Makefiles.

[PATCH 34/39] scripts/headers_check.pl: correct RE in header CONFIG leak check

[Sam Ravnborg]

From: Robert P. J. Day <rpjday@crashcourse.ca>

Correct the regular expression in scripts/headers_check.pl to include '_'
as a valid character in the class; otherwise, the check will report a
"leaked" symbol of CONFIG_A_B_C as merely CONFIG_A.

This patch will make no difference whatsoever in the current kernel tree
as the call to the perl routine that does that check is currently
commented out:

                &check_include();
                &check_asm_types();
                &check_sizetypes();
                &check_prototypes();
                # Dropped for now. Too much noise &check_config();

However, I noticed that problem when I was building the yum downloadable
kernel source rpm for fedora 11 (beta), which *does* run that check, and
that's where the problem became obvious.

[PATCH 36/39] menu: fix embedded menu presentation

[Sam Ravnborg]

From: Randy Dunlap <randy.dunlap@oracle.com>

The STRIP_ASM_SYMS kconfig symbol mucks up the embedded menu because
STRIP_ASM_SYMS is in the middle of the embedded menu items but it does not
depend on EMBEDDED.  Move it to beyond the end of the embedded menu so
that the menu is presented correctly.

Or if STRIP_ASM_SYMS should depend on EMBEDDED, that can also be fixed.
