savedefconfig will save a minimal config to a file
named "defconfig".
The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.
The implementation was tested against several minimal
configs for arm which was created using brute-force.
There was one regression related to default numbers
which had their valid range further limited by another symbol.
Sample:
config FOO
int "foo"
default 4
config BAR
int "bar"
range 0 FOO
If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.
This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

Consider following kconfig file:
config TEST1
bool "test 1"
depends on TEST2
config TEST2
bool "test 2"
depends on TEST1
Previously kconfig would report:
foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2
With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5: symbol TEST2 depends on TEST1
foo:1: symbol TEST1 depends on TEST2
Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving
several files.
Patch is originally from Roman Zippel with a few adjustments by Sam.

When we add a new config symbol save the file/line
so we later can refer to their location.
The information is saved as a property to a config symbol
because we may have multiple definitions of the same symbol.
This has the side-effect that a symbol always has
at least one property.

Rename to a name that better match the other kconfig targets.
listnewconfig shall read as:
- list new options compared to current configuration
New options are now written to stdout so one can redirect the output.
Do not exit with an error code if there is new options.
These are feature changes compared to the original
nonint_oldconfig - but as this feature has not yet been in a
released kernel it should not matter.
It is still possible to do:
make listnewconfig

The list of options supported by conf is growing
and their abbreviation did not resemble anything usefull.
So drop the single letter options in favour of long options.
The long options are named equal to what we know from
the make target.
The internal implmentation was changed to match this,
resulting in much more readable code.
Support for short options is dropped - no one is supposed
to call this program direct anyway.

There seems to be a kconfig bug due to MODULES not always being
evaluated if no .config is found. Take the following Kconfig as an
example:
config MODULES
def_bool y
config FOO
def_tristate m
With no .config, the following configuration is generated:
CONFIG_MODULES=y
CONFIG_FOO=y
With an empty .config, the following:
CONFIG_MODULES=y
CONFIG_FOO=m
Tristate choice statements can also exhibit the problem, due to having an
implicit rev_dep (select) containing "m".
The problem is that MODULES is never evaluted in conf_read_simple() unless
there's a .config. The following patch fixes this.

nconfig segfaults when help text contains the character '%'. For a quick
example, navigate to the kernel compression options and get the help for
bzip2. Doing so triggers a call to mvwprintw() with a string containing
'%' and no extra arguments to fill in the specifier's value. Fix this
case by printing the literal string retrieved from the kconfig.

The "select" statement in Kconfig files allows the enabling of options
even if they have unmet direct dependencies (i.e. "depends on" expands
to "no"). Currently, the "depends on" clauses are used in calculating
the visibility but they do not affect the reverse dependencies in any
way.
The patch introduces additional tracking of the "depends on" statements
and prints a warning on selecting an option if its direct dependencies
are not met.

You can also notice this bug when using gconfig/xconfig.
It's because the SYMBOL_DEF_USER bit of an invisible symbol is cleared
when the config file is read:
int conf_read(const char *name)
{
...
for_all_symbols(i, sym) {
if (sym_has_value(sym) && !sym_is_choice_value(sym)) {
/* Reset values of generates values, so they'll appear
* as new, if they should become visible, but that
* doesn't quite work if the Kconfig and the saved
* configuration disagree.
*/
if (sym->visible == no && !conf_unsaved)
sym->flags &= ~SYMBOL_DEF_USER;
...
}
But a menu item which represents an invisible symbol is still
visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER
bit should be set to indicate it's not NEW.

This patch has been around for a long time in Fedora and Red Hat Enterprise
Linux kernels and it may be useful for others. The nonint_oldconfig target
will fail and print the unset config options while loose_nonint_oldconfig will
simply let the config option unset. They're useful in distro kernel packages
where the config files are built using a combination of smaller config files.
Arjan van de Ven wrote the initial nonint_config and Roland McGrath added the
loose_nonint_oldconfig.

Quote Tim Bird:

| completely missing until I disable CC_OPTIMIZE_FOR_SIZE.
|
| Is there any way to have the menu item appear, but be
| unsettable unless the SIZE option is disabled? I'm
| not a Kconfig guru...
I myself found this useful too. For example, I need to test
ftrace/tracing and want to be sure all the tracing features are
enabled, so I enter the "Tracers" menu, and press <Z> to
see if there is any config hidden.
I also noticed gconfig and xconfig have a button "Show all options",
but that's a bit too much, and I think normally what we are not
interested in those configs which have no prompt thus can't be
changed by users.
Exmaple:
--- Tracers

- - Kernel Function Graph Tracer
[*] Interrupts-off Latency Tracer
- - Preemption-off Latency Tracer
[*] Sysprof Tracer
Here you can see 2 tracers are not selectable, and then can find

Doing the following:
make LSMOD=file localmodconfig
Will make the streamline-config code use the given file instead of
lsmod. If the file is an executable, it will execute it, otherwise
it will read it as text.
make LSMOD=/my/local/path/lsmod localmodconfig
The above will execute the lsmod in /my/local/path instead of the
lsmods that may be located elsewhere.
make LSMOD=embedded_board_lsmod localmodconfig
The above will read the "embedded_board_lsmod" as a text file. This
is useful if you are doing a cross compile and need to run the
config against modules that exist on an embedded device.
Note, if the LSMOD= file does is not a path, it will add the
path to the object directory. That is, the above example will look
for "embedded_board_lsmod" in the directory that the binary will
be built in (the O=dir directory).

If lsmod is not found in any of those paths, it defaults to use
just lsmod and hopes that it lies in the path of the user.

While looking for something else I noticed that the symbol
hash function used by kconfig is quite poor. It doesn't
use any of the standard hash techniques but simply
adds up the string and then uses power of two masking,
which is both known to perform poorly.
The current x86 kconfig has over 7000 symbols.
When I instrumented it showed that the minimum hash chain
length was 16 and a significant number of them was over
30.
It didn't help that the hash table size was only 256 buckets.
This patch increases the hash table size to a larger prime
and switches to a FNV32 hash. I played around with a couple of hash
functions, but that one seemed to perform best with reasonable
hash table sizes.
Increasing the hash table size even further didn't
seem like a good idea, because there are a couple of global
walks which walk the complete hash table.
I also moved the unnamed bucket to 0. It's still the longest
of all the buckets (44 entries), but hopefully it's not
often hit except for the global walk which doesn't care.
The result is a much nicer distribution:
(first column bucket length, second number of buckets with that length)
1: 3505
2: 1236
3: 294
4: 52
5: 3
47: 1 <--- this is the unnamed symbols bucket
There are still some 5+ buckets, but increasing the hash table
even more would be likely not worth it.
This also cleans up the code slightly by removing hard coded
magic numbers.
I didn't notice a big performance difference either way
on my Nehalem system, but I presume it'll help somewhat
on slower systems.

replacement for menuconfig was mentioned (by Sam Ravnborg).
Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.

Help text for certain config options is very extensive (the text
includes the names of all other options the option in question depends
on). Long lines are not wrapped, making it impossible to see the list
without scrolling horizontally.
This patch adds some logic which wraps help screen lines at word
boundaries to prevent truncating.
Tested by running
ARCH=powerpc make menuconfig O=/tmp/build
which shows that the long lines are now wrapped, and
ARCH=powerpc make xconfig O=/tmp/build
to demonstrate that it still compiles and operates as expected.

The streamline_config.pl misses the if conditions for checking
dependencies. For Kconfigs with the following construct:
if MEDIA_SUPPORT
config VIDEO_DEV
[...]
If VIDEO_DEV was enabled, the script will miss the fact that MEDIA_SUPPORT
is also needed.
This patch changes streamline_config.pl to include if conditions into
the dependencies of configs.

To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

If a config does not have a prompt, it must be selected.
streamline_config.pl keeps track of all configs that select other configs.
If a config that does not have a prompt needs to be set to enable a
current module, it will include all configs that select it.
Note, streamline_config.pl does not enable modules that are not already
enabled. It only keeps enabled those that were enabled and might be
needed to compile the current modules.
The code to find the selects of a config is after the code that
adds the depends. But if a config needed selects but had no dependencies,
it would not be set. Because the code would stop before getting to
the select.

Running the streamline_config.pl script manually can still be confusing

streamline_config.pl is a very powerful tool. For those that install
a kernel to a new box using the config file from the distribution know that
it can take forever to compile the kernel.
Making a custom config file that will still boot your box, but bring
down the compile time of the kernel can be quit painful, and to ask
someone that reported a bug to do this can be a large burdon since that
person may not even know how to build a kernel.
This script will perform "lsmod" to find all the modules loaded on the
current running system. It will read all the Makefiles to map which
CONFIG enables a module. It will read the Kconfig files to find the
dependencies and selects that may be needed to support a CONFIG.
Finally, it reads the .config file and removes any module "=m" that is
not needed to enable the currently loaded modules. The output goes to
standard out.
Here's a way to run the script. From the Linux directory that holds
a distribution .config.
$ scripts/kconfig/streamline_config.pl arch/x86/Kconfig > config-sl
$ mv .config config-save
$ mv config-sl .config
$ make oldconfig
Now you have a .config that will still build all your modules, but also
take much less time to build the kernel.

The offending string is the following, and it's located in
drivers/staging/panel/Kconfig:72:
"'\e[L' which are specific to the LCD, and a few ANSI codes. The"
looks to me like gettext expects strings in printf format, so in
this case it thinks "\e" is a control sequence but doesn't recognise
it as a valid one.
A valid solution would be to tell kxgettext to automatically
escape this kind of strings in the */config.pot he produces, so that
msguniq would not complain.

'make randconfig' uses glibc's rand function, and the seed of
that PRNG is set via:
srand(time(NULL));
But 'time()' only increases once every second - freezing the
randconfig result within a single second.
My Nehalem testbox does randconfig much faster than 1 second
and i have a few scripts that do 'randconfig until condition X'
loops.
Those scripts currently waste a lot of CPU time due to randconfig
changing its seed only once per second currently.
Change the seed to be micrseconds based. (I checked the statistical
spread of the seed - the now.tv_sec*now.tv_usec multiplication
there further improves it.)

If you use KCONFIG_ALLCONFIG (even with empty file) you get broken
allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious
massive fallout.
Breakage had been introduced when conf_set_all_new_symbols() got used
for allmodconfig et.al.
What happens is that sym_calc_value(modules_sym) done in
conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES.
When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER]
on everything, but it has no effect on sym->curr for the symbols that
already have SYMBOL_VALID - these are stuck.
Solution: use sym_clear_all_valid() in there. Note that it makes
reevaluation of modules_sym redundant - sym_clear_all_valid() will do
that itself.

As choice dependency are now fully checked, it's quite easy to add support
for named choices. This lifts the restriction that a choice value can only
appear once, although it still has to be within the same group,
but multiple choices can be joined by giving them a name.
While at it I cleaned up a little the choice type logic to simplify it a

You've hit the rather subtle rules of select vs default. What happened is
that SERIO is selected to m, but SERIO_I8042 isn't selected so the default
of y is used instead.
We already had the problem in the past that select and default don't work
well together, so this patch cleans this up and makes the rule hopefully
more straightforward. Basically now the value is calculated like this:
(value && dependency) || select
where the value is the user choice (if available and the symbol is
visible) or default.
In this case it means SERIO and SERIO_I8042 are both set to y due to their
default and if SERIO didn't had the default, then the SERIO_I8042 value
would be limited to m due to the dependency.
I tested this patch with more 10000 random configs and above case is the
only the difference that showed up, so I hope there is nothing that
depended on the old more complex and subtle rules.

either. PTXdist menuconfig now works on Windows linked with PDCurses and

Switch from doing our own parsing of command line arguments to
using getopt(3) to do it. Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).
Note some subtle changes:
- The argument '-?' is no longer supported.
- '-h' is not treated as an error, so output goes to stdout, and we
exit with '0'.
- There is no compatibility checking amongst arguments; the last option
will simply override earlier options. For example, 'conf -n -y foo'
is perfectly valid now (input_mode will be set_yes). Previously, that
would have been an error ("can't find file -y").

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:
- 0f855aa64b ("kconfig: add helper to set
config symbol from environment variable")
- 2a113281f5 ("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.

After unification of the Kconfig files and

it required only trivial changes to enable

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.

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.

This reverts commit a5bf3d891a.
David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'. Unfortunately the same
notation is used for comments. If the implied option is module capable,
user can still switch between Y and M, all without any feedback until she
visits option's help. (try saying M to MAC80211 and then toggling
CFG80211)
This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.
The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.

Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).
The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.
The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.

Run "make xconfig" on a freshly untarred kernel-tree. Look at the floppy disk
icon of the qt application, that has just started: Its in a normal, active

Mouse click on it: .config is being saved.
This patch series changes things so taht
after the mouse click on the floppy disk icon, the icon is greyed out.
If you mouse click on it now, nothing happens.
If you change some CONFIG_*, the floppy disk icon returns to "active state",
that is, if you mouse click it now, .config is written.
This patch:
Returns sym_change_count to reflect the .config's change state.

o menubox now uses parameters to save scroll state (avoids temp file)
o textbox now get text to be displayed as parameter and not a file
o make sure to properly delete subwin's before main windows
o killed unused files: lxdialog.c msgbox.c
o modified return value for ESC to match direct calling
o in a few places the code has been adjusted to 80 char wide
o in textbox a small refactoring was made to make code remotely readable
o in mconf removed all unused stuff (functions/variables)
Following is a list of know short comings:
a) pressing ESC twice will be interpreted as two ESC presses
b) resize does not work. menuconfig needs to be restarted to be adjusted

This fixes one of the worst kbuild warts left - the broken dependencies used
to check and regenerate the .config file. This was done via an indirect
dependency and the .config itself had an empty command, which can cause make
not to reread the changed .config file.
Instead of this we generate now a new file include/config/auto.conf from
.config, which is used for kbuild and has the proper dependencies. It's also
the main make target now for all files generated during this step (and thus
replaces include/linux/autoconf.h).
This also means we can now relax the syntax requirements for the .config file
and we don't have to rewrite it all the time, i.e. silentoldconfig only
writes .config now when it's necessary to keep it in sync with the Kconfig
files and even this can be suppressed by setting the environment variable
KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

The kbuild system takes advantage of an incorrect behavior in GNU make.
Once this behavior is fixed, all files in the kernel rebuild every time,

the incorrect and correct behaviors of GNU make.
For more details on the incorrect behavior, see:

Changes in this patch:

'allnoconfig' is described by 'make help' as a "minimal config", that's not

EMBEDDED was set to Y and most things therein disabled etc. Simply
answering 'no' to all options does not give a minimal config.

While running "make menuconfig" and "make mrproper"
some people experienced that /dev/null suddenly changed
permissions or suddenly became a regular file.
The main reason was that /dev/null was used as output
to gcc in the check-lxdialog.sh script and gcc did
some strange things with the output file; in this
case /dev/null when it errorred out.
Following patch implements a suggestion
from Bryan O'Sullivan <bos@serpentine.com> to
use gcc -print-file-name=libxxx.so.
Also the Makefile is adjusted to not resolve value of
HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.
This prevents us from calling gcc when running make *clean/mrproper

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.

scripts/kconfig/lxdialog/check-lxdialog.sh uses gcc to check for
what libraries are present. Redirect output to /dev/null
so we do not generate an a.out.
Also included support for ncursesw - so if present prefer that
instead of ncurses.
The order is now (first is preferred):
1) ncursesw
2) ncurses
3) curses
The latter is to support SunOS.

Cleaning up the lxdialog Makefile by factoring out the
ncurses compatibility checks.
This made the checks much more obvious and easier to extend.
