* kconfig: Add error handling to KCONFIG_ALLCONFIGEric W. Biederman2012-05-051-9/+9
| | | | | | | | | | | | | | | | | | | | - 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. Signed-off-by: Eric W.

* Documentation: mention scripts/diffconfig toolJavi Merino2012-03-301-5/+3
| | | | | | | | | | | The kconfig documentation suggests using plain 'diff' to compare config files and then adds "Yes, we need something better here". Commit a717417e7f96 ("kconfig: add diffconfig utility") added what that comment was looking for.

* | kconfig: add alldefconfigSam Ravnborg2010-08-031-1/+1
|/ | | | | | | | | | | | alldefconfig create a configuration with all values set to their default value (form the Kconfig files). This may be useful when we try to use more sensible default values and may also be used in combination with the minimal defconfigs.

* kbuild: generate modules.builtinMichal Marek2009-12-121-0/+5
| | | | | | | | | | | 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.

* kconfig: resort the documentation of the environment variablesMarkus Heidelberg2009-06-091-56/+60
| | | | | | | | | | | | | | | | | 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'".

* kbuild: make *config usage docsRandy Dunlap2009-01-021-0/+188
Create a kconfig user assistance guide, with a few tips and hints about using menuconfig, xconfig, and gconfig. Mostly contains user interface, environment variables, and search topics, along with mini.config/custom.config usage.
