| * Documentation/kconfig: more concise and straightforward search explanationYann E. MORIN2013-07-161-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Re-phrase the explanations on the sorting of search results, in a more concise and complete way. Drop reference to the user's locale when sorting alphabetically, since this is implicit. Reported-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: "Yann E.

| * kconfig: sort found symbols by relevanceYann E. MORIN2013-06-241-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Finally eradicate CONFIG_HOTPLUGStephen Rothwell2013-06-031-1/+1
|/ | | | | | | | | | | | | | | | | | | Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"), it has been basically impossible to build a kernel with CONFIG_HOTPLUG turned off. Remove all the remaining references to it.

* kconfig: implement KCONFIG_PROBABILITY for randconfigYann E. MORIN2013-04-251-0/+27
| | | | | | | | | | | | | | | | | | | | | | | Currently the odds to set each symbol is (rounded): booleans: y: 50% n: 50% tristates: y: 33% m: 33% n: 33% Introduce a KCONFIG_PROBABILITY environment variable to tweak the probabilities (in percentage), as such: KCONFIG_PROBABILITY y:n split y:m:n split ----------------------------------------------------------------- [1] unset or empty 50 : 50 33 : 33 : 34 [2] N N : 100-N N/2 : N/2 : 100-N N:M N+M : 100-(N+M) N : M : 100-(N+M) N:M:L N : 100-N M : L : 100-(M+L) [1] The current behaviour is kept as default, for backward compatibility [2] The solution initially implemented by Peter for Buildroot, see: http://git.buildroot.org/buildroot/commit/?id=3435c1afb5 Signed-off-by: Peter Korsgaard <jacmet@uclibc.org> [yann.morin.1998@free.fr: add to Documentation/] Signed-off-by: "Yann E.

* kconfig: allow specifying the seed for randconfigYann E. MORIN2013-04-251-0/+9
| | | | | | | | | | | | | | | | | | For reproducibility, it can be useful to be able to specify the seed to use to seed the RNG. Add a new KCONFIG_SEED environment variable which can be set to the seed to use: $ make KCONFIG_SEED=42 randconfig $ sha1sum .config 70a128c8dcc61303069e1be352cce64114dfcbca .config $ make KCONFIG_SEED=42 randconfig $ sha1sum .config 70a128c8dcc61303069e1be352cce64114dfcbca .config It's very usefull for eg. debugging the kconfig parser.

* 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 Merino2012-03-311-5/+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.

* 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.

| | | | | | | | | | | | | | | | | 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'".
