2009-03-15kconfig: improve seed in randconfigIngo Molnar
'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.)

2009-03-15kconfig: fix randconfig for choice blocksSam Ravnborg
Ingo Molnar reported that 'make randconfig' was not covering choice blocks properly, resulting in certain config options being left out of randconfig testing altogether. With the following patch we: - properly randomize choice value for normal choice blocks - properly randomize for multi choice blocks - added several comments to explain what is going on The root cause of the bug was that SYMBOL_VALID was set on the symbol representing the choice block so clearing this did the trick initially. But testign revealed a few more issues that is now fixed.

2008-10-26fix allmodconfig breakageAl Viro
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.

make defconfig generated a lot of output then noone actually read. Use conf_set_all_new_symbols() to generate the default configuration and avoid the chatty output.

2008-07-25kconfig: make oldconfig is now less chattySam Ravnborg
Previously when running "make oldconfig" we saw all the propmt lines from kconfig and noone actully read this. With this patch the user will only see output if there is new symbols. This will be seen as "make oldconfig" runs which does not generate any output. A typical run now looks like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig $ If a new symbol is found then we restart the config process like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig * * Restart config... * * * General setup * Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [Y/n/?] y Local version - append to kernel release (LOCALVERSION) [] ... The bahaviour is similar to what we know when running the implicit oldconfig target "make silentoldconfig". "make silentoldconfig" are run as part of the kernel build process if the configuration has changed. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

2008-02-13kconfig: fix select in combination with defaultRoman Zippel
> The attached .config (with current -git) results in a compile > error since it contains: > > CONFIG_X86=y > # CONFIG_EMBEDDED is not set > CONFIG_SERIO=m > CONFIG_SERIO_I8042=y > > Looking at drivers/input/serio/Kconfig I simply don't get how this > can happen. 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.

2008-02-03kconfig: ignore select of unknown symbolSam Ravnborg
We have had warnings for a long time about select of unknow symbol but the warnings does not really makes sense since we may select a symbol that is relevant and defined in one arch but not in another arch. And as long as we do not use a common set of Kconfig files for all archs lets just ignore this case. Previously we have used this to find bad uses of select but we need a more relaible method to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

2008-01-28kconfig: use getopt() in conf.c for handling command line argumentsAndres Salomon
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").
