scripts: merge_config: add strict mode to fail upon any redefinition

2021-08-09T23:23:39Z

When merging configuration fragments, it might be of interest to identify mismatches (redefinitions) programmatically. Hence add the option -s (strict mode) to instruct merge_config.sh to bail out in case any redefinition has been detected. With strict mode, warnings are emitted as before, but the script terminates with rc=1. If -y is set to define "builtin having precedence over modules", fragments are still allowed to set =m (while the base config has =y). Strict mode will tolerate that as demotions from =y to =m are ignored when setting -y. Signed-off-by: Matthias Maennich Reviewed-by: Lee Jones Signed-off-by: Masahiro Yamada

streamline_config.pl: add softtabstop=4 for vim users

2021-06-29T17:53:45Z

The tab stop for Perl files is by default (at least in emacs) to be 4 spaces, where a tab is used for all 8 spaces. Add a local variable comment to make vim do the same by default, and this will help keep the file consistent in the future when others edit it via vim and not emacs.

streamline_config.pl: make spacing consistent

2021-06-29T17:53:45Z

Patch series "streamline_config.pl: Fix Perl spacing". Talking with John Hawley about how vim and emacs deal with Perl files with respect to tabs and spaces, I found that some of my Perl code in the kernel had inconsistent spacing. The way emacs handles Perl by default is to use 4 spaces per indent, but make all 8 spaces into a single tab. Vim does not do this by default. But if you add the vim variable control: # vim: softtabstop=4 to a perl file, it makes vim behave the same way as emacs. The first patch is to change all 8 spaces into a single tab (mostly from people editing the file with vim). The next patch adds the softtabstop variable to make vim act like emacs by default. This patch (of 2): As Perl code tends to have 4 space indentation, but uses tabs for every 8 spaces, make that consistent in the streamline_config.pl code. Replace all 8 spaces with a single tab.

kconfig: refactor .gitignore

Add '/' prefix to clarify that the generated files exist right under scripts/kconfig/, but not in any sub-directory. Replace '*conf-cfg' with '[gmnq]conf-cfg' to make it explicit, and still short enough. Use '[gmnq]conf' to combine gconf, mconf, nconf, and qconf. Signed-off-by: Masahiro Yamada

kconfig: highlight xconfig 'comment' lines with '***'

2021-04-19T05:58:23Z

Mark Kconfig "comment" lines with "*** ***" so that it is clear that these lines are comments and not some kconfig item that cannot be modified. This is helpful in some menus to be able to provide a menu "sub-heading" for groups of similar config items. This also makes the comments be presented in a way that is similar to menuconfig and nconfig. Signed-off-by: Randy Dunlap Signed-off-by: Masahiro Yamada
