Recently there has been request for a number of new kconfig related targets. In general it boils down to the following: We need to be flexible in what configuration we start out from and how we apply it. We need to be able to apply it in following ways: 1) automated - select defaults for all new symbols => It is used for "make defconfig, make *_defconfig" today 2) interactive - asking user for all new symbols and error out if stdin is redirected 3) list unknown - list all new symbols and do not create a new config With oldconfig today we have two modes: -> One mode where we are very chatty and show all output. -> And the 'silent' mode where we only start being chatty when we see a new symbol. I plan to drop the 'very chatty' mode as I do not see it usefull. So in essense 'make oldconfig' and 'make silentoldconfig' become equal. The commands we have today for kconfig is: # Command line variants make oldconfig make silentoldconfig make defconfig make XXX_defconfig (The other frontends are left out on purpose). The challenge here is to come up with a syntax that allows us to select between the three behaviours, while keeping backward compatibility. The best suggestion I have so far is to say that: a) if defconfig is specified then we use method 1) b) if oldconfig is specified then we use method 2) c) if newconfig is specified then we use method 3) And we add support for a new 'commandline' parameter 'K' so I can say: make K=/proc/config.gz defconfig make K=i386_defconfig defconfig make K=i386_defconfig oldconfig make K=/proc/config.gz newconfig So K is used to specify what config file we use to start out from. Care should be taken to keep the known good targets working as before. Andres Salomon already did some preparational work for this but I need to find a good way to handle the K= parameter. Dave J also posted patches that is useful for 'newconfig'. But I wanted to ask for opinions before diving into implmenting this.
