kconfig: Do not print status messages in make -s mode

2015-04-09T15:44:34Z

Add an -s option to the various frontends and pass it when make -s is used. Also, use $(kecho) instead of @echo in the Makefile. Signed-off-by: Michal Marek

kbuild: add generic mergeconfig target, %.config

2015-03-24T15:48:44Z

"scripts/kconfig/merge_config.sh && make oldconfig" works well enough for merging local config fragments, but Kbuild currently has the entry points only for "kvmconfig" and "tinyconfig". This commit provides the generic target for mergeconfig, so we can manage our own config fragments easily: put "foo.config" in arch/$(SRCARCH)/configs/ or kernel/configs/, and then run "make foo.config". Now "make kvmconfig" is just a shorthand of "make kvm_guest.config". Likewise, "make tinyconfig" is equivalent to "make allnoconfig tiny.config".

merge_config.sh: rename MAKE to RUNMAKE

2015-03-24T15:48:44Z

The variable "MAKE" is used to store the command name that has invoked the Makefile. (Actually, it is already set to "make" if you run this script from a Makefile.) In this script, however, it is used to determine if Make should be run or not. It is not what we usually expect.

merge_config.sh: improve indentation

2015-03-24T15:48:44Z

It is true that we do not want to move the code too far to the right, but something like below is not preferred: if [ "x$PREV_VAL" != "x$NEW_VAL" ] ; then echo Value of $CFG is redefined by fragment $MERGE_FILE: echo Previous value: $PREV_VAL echo New value: $NEW_VAL echo elif [ "$WARNREDUN" = "true" ]; then echo Value of $CFG is redundant by fragment $MERGE_FILE: fi To fix this, call "continue" if the "grep" command fails to find the given CONFIG.

kbuild: mergeconfig: remove redundant $(objtree)

2015-03-24T15:48:44Z

Kbuild always runs in $(objtree). Actually, $(objtree) is always set to "." by the top-level Makefile. We can omit "-O $(objtree)" and "$(objtree)/". Signed-off-by: Masahiro Yamada Reviewed-by: Josh Triplett Reviewed-by: Darren Hart Signed-off-by: Michal Marek

kbuild: mergeconfig: move an error check to merge_config.sh

2015-03-24T15:48:44Z

Currently, "make tinyconfig" does not work with "-j" option. $ make mrproper $ make -j8 tinyconfig HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf scripts/kconfig/conf --allnoconfig Kconfig # # configuration written to .config # scripts/kconfig/Makefile:122: *** You need an existing .config for this target. Stop. make: *** [tinyconfig] Error 2 As shown above, "allnoconfig" has created the .config file before mergeconfig is called, but Make still raises a false alarm because of some sort of race condition. We can fix this issue by moving the error check to the shell script. Anyway, scripts/kconfig/merge_config.sh always requires an existing .config as a base file. It is reasonable to check its existence in the shell script. Signed-off-by: Masahiro Yamada Reviewed-by: Josh Triplett Reviewed-by: Darren Hart Signed-off-by: Michal Marek
