Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs. If somebody knows how to create a minimal .config with a certain kconfig symbol (and its dependencies) set, I'd love to hear about it.

If you find this out, please, share!

Are you guys looking for "make savedefconfig" ??

No. It is more like:

I have changed this strange driver.

I want to compile-test my changes.

I need a defconfig which would have this driver enabled. I also want to know <arch> for my "make ARCH=<arch>" command.

Not quite the same thing, but I sent this a while ago:

http://lkml.indiana.edu/hypermail/linux/kernel/1304.3/02847.html

My "softdepends" feature is probably not needed, as pointed out in the thread, as the behavior can be implemented with the current Kconfig language just fine.

I had a quick look at fbdev drivers, and some of them compile fine on all (well, arm and x86) archs. But many do have real arch dependencies.

I think it'd be a good long term goal to make drivers arch-independent, and add CONFIG_SHOW_ALL_DRIVERS or such, which would allow compiling drivers that are not used on your arch, but still compile fine.
