As shown above, "allnoconfig" has created the .config file before

We can fix this issue by moving the error check to the shell script.
Anyway, scripts/kconfig/merge_config.sh always requires an existing

Currently, Kconfig descriptions that use multi-byte UTF-8 characters
(such as MTD_NAND_CAFE) will have their menu entries dropped from the
'make nconfig' ncurses menu, and all subsequent entries in the same
window will be omitted. This seems to be due to the ncurses 'menu'
library, which does not traditionally handle UTF-8 >8-bit characters
properly.
The ncursesw library ('w' is for "wide") is written to handle these
UTF-8 characters, and is practically a drop-in replacement at the source
level. Use it by default, if available.

Since commit 5d2acfc7b9 ("kconfig: make

"make allnoconfig" disables every possible config option.
However, a few configuration options (CC_OPTIMIZE_FOR_SIZE,
OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few
choices exist (compression, highmem, allocator) for which a non-default
option produces a smaller kernel.
Add a "tinyconfig" option, which starts from allnoconfig and then sets
these options to configure the tiniest possible kernel. This provides a
better baseline for embedded systems or efforts to reduce kernel size.

"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.
However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.
To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT). allnoconfig will then disable all the
symbols hidden behind those.

Previously, it was possible to have more than one symbol with the

in fact control tristates.
Since this does not make much sense, only allow at most one symbol to
control tristates.
Note: it is still possible to have more than one symbol that control
tristates, but indirectly:
config MOD1
bool "mod1"
select MODULES
config MOD2
bool "mod2"

Currently, the 'MODULES' symbol is hard-coded to be the default symbol
that enables/disables tristates, if no other symbol was declared with
'option modules'.
While this used to be needed for the Linux kernel, we now have an
explicit 'option modules' attached to the 'MODULES' symbol (since
cset 11097a036), so we no longer need to special-case it in the
kconfig code.
Furthermore, kconfig is extensively used out of the Linux kernel, and
other projects may have another meaning for a symbol named 'MODULES'.
This patch changes the way we enable/disable tristates: if a symbol was
found with 'option modules' attached to it, then that symbol controls
enabling tristates. Otherwise, tristates are disabled, even if a symbol
named 'MODULES' exists.

When a symbol changes type from tristate to bool, and was previously set to
'm', a subsequent silentoldconfig would warn about inconsistency, such as:
include/config/auto.conf:3014:warning: symbol value 'm' invalid for
HOTPLUG_PCI_PCIE
Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal):
git checkout 1fe0135
make mrproper
make allmodconfig
make silentoldconfig
git checkout aa8032b
make allmodconfig
make silentoldconfig
Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was
previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig,
but then was set to 'y' by the second allmodconfig. Then the second
silentoldconfig prints the warning.
The warning in this case is a spurious warning, which happens at the time
kconfig tries to detect symbols that have changed, to touch the empty
header files in include/config used for dependency-tracking by make.
Silence the warning when we read the old auto.conf file, since it is
perfectly legit that a symbol changed type since the previous call.

For example, given those two files (Thomas' test-case):
---8<--- Config.test.in
config OPTIONA
bool "Option A"
choice
prompt "This is a choice"
config CHOICE_OPTIONA
bool "Choice Option A"
config CHOICE_OPTIONB
bool "Choice Option B"
endchoice
config OPTIONB
bool "Option B"
---8<--- Config.test.in
---8<--- config.defaults
CONFIG_OPTIONA=y
---8<--- config.defaults
And running:
./scripts/kconfig/conf --randconfig Config.test.in
does properly randomise the two choice symbols (and the two booleans).
However, running:
KCONFIG_ALLCONFIG=config.defaults \
./scripts/kconfig/conf --randconfig Config.test.in
does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)
This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.

Changes v3 -> v4
- fix previous issue where some choices would not be set, which would
cause silentoldconfig to ask for them and was then breaking this
workflow (as reported by Arnd and Sedat):
KCONFIG_ALLCONFIG=foo.defconfig make randconfig
make silentoldconfig </dev/nullo
which I have tested (3h28min!) with:
touch defconfig
for(( i=0; i<10000; i++ )); do
KCONFIG_ALLCONFIG=$(pwd)/defconfig make randconfig >/dev/null 2>&1
make silentoldconfig </dev/null >/dev/null 2>&1 || break
done
which did not break at all.
- change done in v3 (below) is already fixed by a previous patch
Changes v2 -> v3
- ensure only one symbol is set in a choice
Changes v1 -> v2:
- further postpone setting that a choice has a value until
one is indeed set
- do not print symbols that are part of an invisible choice
Because of choice-in-a-choice constructs, it can happen that not all
symbols are assigned a value during randconfig, leading in rare cases
to this situation:
---8<--- choice-in-choice.in
choice
bool "A/B/C"
config A
bool "A"
config B
bool "B"
if B
choice
bool "E/F"
config E
bool "E"
config F
bool "F"
endchoice
endif # B
config C
bool "C"
endchoice
---8<---
$ ./scripts/kconfig/conf --randconfig choice-in-choice.in
[--SNIP--]
$ ./scripts/kconfig/conf --silentoldconfig choice-in-choice.in </dev/null
[--SNIP--]
A/B/C
1. A (A)
> 2. B (B)
3. C (C)
choice[1-3]: 2
E/F
> 1. E (E) (NEW)
2. F (F) (NEW)
choice[1-2]: aborted!
Console input/output is redirected. Run 'make oldconfig' to update
configuration.
Fix this by looping in randconfig for as long as some symbol gets assigned
a value.
Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP),
which uses this choice-in-a-choice construct, and exhibits this problem.
The example above is just a stripped-down minimalist test-case.

When searching for symbols, return the symbols sorted by relevance.
Sorting is done as thus:
- first, symbols that match exactly
- then, alphabetical sort
Since the search can be a regexp, it is possible that more than one symbol
matches exactly. In this case, we can't decide which to sort first, so we
fallback to alphabeticall sort.
Explain this (new!) sorting heuristic in the documentation.

Changes v1->v2:
- drop the previous, complex heuristic in favour of a simpler heuristic
that is both easier to understand, *and* to maintain (Jean)
- explain sorting heuristic in the doc (Jean)
Currently, randconfig may set more than one symbol in a given choice.
Given this config file:
config A
bool "A"
if A
choice
bool "B/C/D"
config B
bool "B"
config C
bool "C"
config D
bool "D"
endchoice
endif # A
Then randconfig generates such .config files (case where A is not set is not
shown below for brevity), and where only the right-most .config is valid:
CONFIG_A=y CONFIG_A=y CONFIG_A=y
CONFIG_B=y CONFIG_B=y CONFIG_B=y
CONFIG_C=y # CONFIG_C is not set # CONFIG_C is not set
# CONFIG_D is not set CONFIG_D=y # CONFIG_D is not set
That is, in a randomised choice, the first symbol is always selected,
and at most one other symbol may be selected.
This is due to symbol randomised in a choice not being properly flagged
as having a value.
Fix that by flagging those symbols adequately: have a user-defined value,
and be not valid (to force recalculation of the symbol).
Note: if the choice is not conditional, then the randomisation is properly
done.

Yann had some more ideas on improvements:
"What would be nice is an improvement that scales the choice window to
the number of entries in the choice. If there are a lot of choice
entries, then the choice popup grows in height (but does not overflow
the screen of course). So, instead of seeing only 6 entries, we'd see
as much as possible in the current screen.
Ditto for the width: the popup adapts to the longest prompt (but does
not overflow the screen either, of course), so prompts are not
truncated."

menu_add_prop() applies upper menus' visibilities to actual prompts
by AND-ing the prompts visibilities with the upper menus ones.
This creates a further reference to the menu's visibilities and when
the expression reduction functions do their work, they may remove or
modify expressions that have multiple references, thus causing
unpredictable side-effects.
The following example Kconfig constructs a case where this causes
problems: a menu and a prompt which's visibilities depend on the same
symbol. When invoking mconf with this Kconfig and pressing "Z" we
see a problem caused by a free'd expression still referenced by the
menu's visibility:
------------------------------------------------------------------------
mainmenu "Kconfig Testing Configuration"
config VISIBLE
def_bool n
config Placeholder
bool "Place holder"
menu "Invisible"
visible if VISIBLE
config TEST_VAR
bool "Test option" if VISIBLE
endmenu
------------------------------------------------------------------------
This patch fixes this problem by creating copies of the menu's
visibility expressions before AND-ing them with the prompt's one.

Searching for PPC_EFIKA results in a segmentation fault, and it's
because get_symbol_prop() returns NULL.
In this case CONFIG_PPC_EFIKA is defined in arch/powerpc/platforms/

this symbol when it parses sound/soc/fsl/Kconfig:

A bug was reported that caused localmodconfig to not keep all the
dependencies of ATH9K. This was caused by the kconfig file:
In drivers/net/wireless/ath/Kconfig:
---
if ATH_CARDS
config ATH_DEBUG
bool "Atheros wireless debugging"
---help---
Say Y, if you want to debug atheros wireless drivers.
Right now only ath9k makes use of this.
source "drivers/net/wireless/ath/ath5k/Kconfig"
source "drivers/net/wireless/ath/ath9k/Kconfig"
source "drivers/net/wireless/ath/carl9170/Kconfig"
source "drivers/net/wireless/ath/ath6kl/Kconfig"
source "drivers/net/wireless/ath/ar5523/Kconfig"
source "drivers/net/wireless/ath/wil6210/Kconfig"
endif
---
The current way kconfig works, it processes new source files after the
first file is completed. It creates an array of new source config files
and when the one file is finished, it continues with the next file.
Unfortunately, this means that it loses the fact that the source file is
within an "if" statement, and this means that each of these source file's
configs will not have the proper dependencies set.
As ATH9K requires ATH_CARDS set, the localmodconfig did not see that
dependency, and did not enable ATH_CARDS. When the oldconfig was run, it
forced ATH9K to be disabled.

Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG
is specified.
For example, given those two files (Thomas' test-case):
---8<--- Config.test.in
config OPTIONA
bool "Option A"
choice
prompt "This is a choice"
config CHOICE_OPTIONA
bool "Choice Option A"
config CHOICE_OPTIONB
bool "Choice Option B"
endchoice
config OPTIONB
bool "Option B"
---8<--- Config.test.in
---8<--- config.defaults
CONFIG_OPTIONA=y
---8<--- config.defaults
And running:
./scripts/kconfig/conf --randconfig Config.test.in
does properly randomise the two choice symbols (and the two booleans).
However, running:
KCONFIG_ALLCONFIG=config.defaults \
./scripts/kconfig/conf --randconfig Config.test.in
does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)
This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.
Also, as a side-efect, this patch fixes the following case:
---8<---
choice
config OPTION_A
bool "Option A"
config OPTION_B
bool "Option B"
config OPTION_C
bool "Option C"
endchoice
---8<---
which could previously generate such .config files:
---8<--- ---8<---
CONFIG_OPTION_A=y CONFIG_OPTION_A=y
CONFIG_OPTION_B=y # CONFIG_OPTION_B is not set
# CONFIG_OPTION_C is not set CONFIG_OPTION_C=y
---8<--- ---8<---
Ie., the first entry in a choice is always set, plus zero or one of
the other options may be set.
This patch ensures that only one option may be set for a choice.

Because the modules' symbole (CONFIG_MODULES) may not yet be set when
we check a symbol's tristate capabilty, we'll always find that tristate
symbols are booleans, even if we randomly decided that to enable modules:
sym_get_type(sym) always return boolean for tristates when modules_sym
has not been previously set to 'y' *and* its value calculated *and* its
visibility calculated, both of which only occur after we randomly assign
values to symbols.
Fix that by looking at the raw type of symbols. Tristate set to 'm' will
be promoted to 'y' when their values will be later calculated.

The current code does this:
if [ -f /usr/include/ncursesw/curses.h ]; then

elif [ -f /usr/include/ncurses/ncurses.h ]; then

elif [ -f /usr/include/ncurses/curses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
[...]
This is merely inconsistent:
- adding the full path to the directory in the -I directive,
- especially since that path is already a sub-path of the system
include path,
- and then repeating the sub-path in the #include directive.
Rationalise each include directive:
- only use the filename in the #include directive,
- keep the -I directives: they are always searched for before the
system include path; this ensures the correct header is used.
Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
$ pkg-config --cflags ncursesw
-I/usr/include/ncursesw
This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.

Viresh noticed when using merge_config.sh that a source softlink

The problem arises due to the previous commit 409f117e2d

we still pass '-O=.' to the make command, which then generates
a source softlink to ./
This patch adds an extra check so if there is no -O specified
to merge_config.sh, we don't pass one on to make.

When building ncurses with --with-termlib several symbols get moved from
libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one
additionally needs to link with libtinfo.so.
The ncurses pkg-config module will be used to detect the necessary libs for
linking. If not available the old way of directly specifying libs will be

The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).
The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.
This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

"Here are two fixes I intended to send after v3.6-rc7, but failed to do
so. So please pull them for v3.7-rc1 and they will be picked up by
stable.
The first one fixes gcc -x <language> syntax in various build-time
tests, which icecream and possible other gcc wrappers did not
understand (and yes, icecream is going to be fixed as well).
The second one fixes make tar-pkg so that unpacking the tarball does
not replace the /lib -> /usr/lib symlink on recent Fedora releases."
* 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kbuild: Fix gcc -x syntax
kbuild: Do not package /boot and /lib in make tar-pkg
The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

The make target 'oldnoconfig' is a misnomer. It doesn't set new symbols
to 'n', but instead sets it to their default values.
Unfortunately, assuming that it actually did this, broke ktest in some
of its tests. For example, the tests to create a minimum config and even
a config bisect, depends on removing various configs and using
oldnoconfig to get rid of other configs that may have depended on it.
But because some configs that it was trying to disable, were in fact
default enabled, this caused those configs to re-enable and corrupt the
test.
I thought about fixing oldnoconfig, but I'm afraid that people are
already dependent on its current behavior. Instead, I'm just updating
the documentation to state that it sets the new symbols to their default
values and not to 'n'.
Ideally, this would be called, 'olddefconfig' and we have an
'oldnoconfig' that actually disables the new symbols. But it's useless
for me now. If it changed, ktest would need to be consistent between
each version, and that would be to difficult to detect. I'll handle this
issue with ktest with other means.

There are some cases that a required module does not have a prompt
and needs to have another module enabled that selects it to be set.
As localmodconfig is conservative and tries to make the minimum config
without breaking the user's kernel, or keeping the user from using
devices that were loaded when the lsmod was done, all modules that
select this module will also be enabled.
If you needed module A, but module A did not have a prompt but needed
module B to be selected, localmodconfig would make sure B was still
enabled. If not only B selected A, but C, D, E, F, and G also
selected A, then all of those would also be included, as well as the
modules they depend on. This ballooned the number of configs that
localmodconfig would keep.
The fix here is to process the depends first, and then record those
configs that did not have a prompt and needed to be selected.
After the depends are done, check what configs are needed to select
the configs in the list, and if a config that selects it is already
set, then we don't need to do anything else.
If no config that selects the config is set, then just pick one and
try again.
This change brought down the number of selected modules from 290
to 67! Both before and after were run against a config that had 3095
modules enabled.

Read in the entire config file. If there's a config that we depend on
that happens to be in the core set (not a module) then we do not need
to process it as a module.
Currently, we follow the entire depend and selects even if they
are enabled as core and not modules. By checking to make sure that we
only look at modules we can drop the count a little.
From one of my tests, localmodconfig went from taking 3095 set modules
down to 356 before this patch, and down to 290 modules after the change.

carrying this any further into the future.
One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

Prevent subtle surprises to both people working on the kconfig code
and people using make allnoconfig allyesconfig allmoconfig and
randconfig by only attempting to read a config file if
KCONFIG_ALLCONFIG is set.
Common sense suggests attempting to read the extra config files does
not make sense unless requested. The documentation says the code
won't attempt to read the extra config files unless requested.
Current usage does not appear to include people depending on the code
reading the config files without the variable being set So do the
simple thing and stop reading config files when passed
all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment
variable is set.

- Only try to read the file specified if KCONFIG_ALL_CONFIG is set to
something other than the empty string or "1".
- Don't use stat to check the name passed to conf_read_simple so that
zconf_fopen can find the file in the current directory or in SRCTREE
removing a extremely source of confusing failure, where KCONFIG_ALL_CONFIG
was not interpreted with respect to the directory make was called in.
- If conf_read_simple fails complain clearly and stop processing.
Allowing the simple debugging of typos.
- Clearly document the behavior so it is clear to users which
values are treated as flags and which values are treated as
filenames.

We've now fixed IS_ENABLED() and friends to not require any special
"__enabled_" prefixed versions of the normal Kconfig options, so delete
the last traces of them being generated.

This reverts commit 953742c8fe.
Dumping two lines into autoconf.h for all existing Kconfig options
results in a giant file (~16k lines) we have to process each time we
compile something. We've weaned IS_ENABLED() and similar off of
requiring the __enabled_ definitions so now we can revert the change
which caused all the extra lines.

Provide a -r option to display when fragments contain redundant
options. This is really useful when breaking apart a config into
fragments, as well as cleaning up older fragments.

Take the first config fragment and use it verbatim as the initial config
set. This avoids running the verification loop for the first file, as
nothing has actually been merged at this point. This significantly
increases performance for large config fragments.

Running `oldconfig' after any of the following configuration change:
either trivial addition, such as:
config A
bool "A"
choice
prompt "Choice ?"
depends on A
config CHOICE_B
bool "Choice B"
config CHOICE_C
bool "Choice C"
endchoice
or more tricky change:
OLD KCONFIG | NEW KCONFIG
|
| config A
| bool "A"
|
choice | choice
prompt "Choice ?" | prompt "Choice ?"
|
config CHOICE_C | config CHOICE_C
bool "Choice C" | bool "Choice C"
|
config CHOICE_D | config CHOICE_D
bool "Choice D" | bool "Choice D"
endchoice |
| config CHOICE_E
| bool "Choice E"
| depends on A
| endchoice
will not cause the choice to be considered as NEW, and thus not be
asked. The cause of this behavior is that choice's novelty are computed
statically right after the saved configuration has been read. At this
point, the new dependency's value is still unknown and asserted to be
`no'. Moreover, no update to this decision is made afterward.
Correct this by dynamically evaluating a choice's novelty, and removing the
static evaluation.

menuconfig: let make not report error when not save configuration
Pressing ESC should cancel the yes/no dialog and return back to
the main menu, but not exit from menuconfig.

Reinhard Tartler discovered a corner case of calling xfwrite() where the
length of the string is zero.
Arnaud Lacombe suggested to use assertion for the corner case, as
fwrite(3) is currently used:
1) in comment printers. Empty comment are not allowed.
2) in a callback passed to expr_print(), where the string printed is
either NULL OR non-empty.
3) in the lexer, auto-generated, and unused.
I feel using assertion is a good solution:
1) It cleanly takes care of the above-mentioned corner case.
2) It can be easily disabled by defining NDEBUG.
3) It asserts xfwrite() is simply a wrapper for fwrite().

I find every time when I choice the 'NO' button at the dialog
which let me choice whether to save the configuration before exit
menuconfig, it always report the blow:
" GEN /mnt/sda7/home/build/test/Makefile
HOSTCC scripts/kconfig/mconf.o
HOSTLD scripts/kconfig/mconf
scripts/kconfig/mconf Kconfig
Your configuration changes were NOT saved.
