kconfig: obey KCONFIG_ALLCONFIG choices with randconfig.

2007-12-23T20:54:37+00:00

Currently when using KCONFIG_ALLCONFIG with randconfig the choice options
are clobbered.  As recommended by Roman, this adds an is_new test to see
whether to select a new option or obey the existing one.

This is a resend of the earlier patch a couple of weeks ago, since there
was no reply.  Original thread is at http://lkml.org/lkml/2007/11/28/94

x86: simplify "make ARCH=x86" and fix kconfig all.config

2007-11-17T16:35:43+00:00

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
all.config.

For a fix the diffstat is nice:
 6 files changed, 3 insertions(+), 36 deletions(-)

The patch reverts these commits:
 - 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set
   config symbol from environment variable")
 - 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to
   set 64BIT with all*config targets")

Roman Zippel pointed out that kconfig supported string compares so
the additional complexity introduced by the above two patches were
not needed.

With this patch we have following behaviour:

  # make {allno,allyes,allmod,rand}config [ARCH=...]
  option \ host arch      | 32bit         | 64bit
  =====================================================
  ./.                     | 32bit         | 64bit
  ARCH=x86                | 32bit         | 32bit
  ARCH=i386               | 32bit         | 32bit
  ARCH=x86_64             | 64bit         | 64bit

The general rule are that ARCH= and native architecture takes
precedence over the configuration.

So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says.  The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.

This behaviour is consistent with previous behaviour so no
suprises here.

make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

x86: enable "make ARCH=x86"

2007-11-12T20:02:20+00:00

After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".

With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
   => select 64-bit

Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.

kconfig: use $K64BIT to set 64BIT with all*config targets

2007-11-12T20:02:20+00:00

The variable K64BIT can now be used to select the
value of CONFIG_64BIT.

This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n

To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.

kconfig: add helper to set config symbol from environment variable

2007-11-12T20:02:20+00:00

Add conf_set_env_sym() that can set an already defined symbol
based on the value of an environment variable.

Unknown symbols are silently ignored.
A warning is printed if the value of the environment variable
is unexpected.

x86: move i386 and x86_64 Kconfig files to x86 directory

2007-10-25T20:37:02+00:00

After a small change in kconfig Makefile we could
move all x86 Kconfig files to x86 directory.

x86: move defconfig files for i386 and x86_64 to x86

2007-10-25T20:27:41+00:00

With some small changes to kconfig makefile we can now
locate the defconfig files for i386 and x86_64 in
the configs/ subdirectory under x86.
make ARCH=i386 defconfig and make defconfig
works as expected also after this change.
But arch maintainers shall now update a defconfig file in
the configs/ directory.

kconfig: set title bar in xconfig

2007-10-20T18:16:50+00:00

Put kernel version info on title bar in xconfig (qconf) instead of
defaulting to "qconf".
